openimageio now uses qt5, not qt4.
This was causing blender to fail to build in bulk builds and on systems
where qt4 was not preinstalled.
XXX needs pullup?
Changelog:

-------------------------------------------------
* Change to internal thread pool to fix rare crash when lowering number of
threads. #2013

comment data. #2001
* JPEG write: robust to accidentally setting the "density" metadata to
values larger than JPEG's 16 bit integer field will accommodate. #2002
* ImageSpec::erase_attribute() fix bug where it got case-sensitivity of the
search backwards when built using std::regex rather than boost::regex.
#2003
Release 1.8.13 (1 Aug 2018) -- compared to 1.8.12
-------------------------------------------------
* Improved finding LibRaw on Windows #1959
* Ensure FFMPEG (if found) is the minimum supported version 2.6. #1963
* Developer goodies: `intrusive_ptr<>` given a dangerous `release()`
method (use with caution). #1986
Release 1.8.12 (1 Jun 2018) -- compared to 1.8.11
-------------------------------------------------
* Build fix for 32 bit Windows -- disable SSE that was making trouble. #1933
* Improved UTF-8 filename support for OpenEXR filenames. #1941

* ImageCache and TextureSystem now have close(filename) and close_all()
methods, which for one file or all files will close the files and release
any open file handles (also unlocking write access to those files on
Windows), but without invalidating anything it knows about the ImageSpec
or any pixel tiles already read from the files, as would happen with a
call to the much more drastic invalidate() or invalidate_all(). #1950

-------------------------------------------------
* oiiotool frame sequence wildcard improvements: fix handling of negative
frame numbers and ranges, also the `--frames` command line option is not
enough to trigger a loop over those frame numbers, even if no other
arguments appear to have wildcard structure. #1894
* TIFF bug fix: read_tile() and read_tiles() input of un-premultiplied tiles
botched the "shape" of the tile data array. #1907
* Windows/MSVC build fix: use the `/bigobj` option on some large modules
that need it. #1900, #1902

* Bug fix in IBA::copy where uninitialized dst image botched its ROI. #1876
* RAW: Important bug fix when dealing with rotated (and vertical) images,
which were not being re-oriented properly and could get strangely
scrambled. #1854
Release 1.8.8 (1 Feb 2018) -- compared to 1.8.7
-------------------------------------------------
* OpenEXR: gracefully detect and reject files with subsampled channels,
which is a rarely-to-never-used OpenEXR feature that we don't support
properly. #1849
* Field3d: Prevent crashes when open fails. #1848
* RAW: Add "raw:HighlightMode" configuration hint to control libraw's
handling of highlight mode processing. #1851

version we suport is 3.6.1. #1843
* simd.h: Minor fixes especially for avx512. #1846
* iv: Drop GLEW and obsolete GL stuff from iv in favor of QOpenGLFunctions,
and fix broken pixelview text rendering. #1834
* On Unix/Linux, add explicit DL library dependency to libOpenImageIO.so
itself instead of only to the binaries and test utilities. #1860
* Build fixes for Hurd OS. #1850
Release 1.8.7 (1 Jan 2018) -- compared to 1.8.6
-------------------------------------------------
* All string->numeric parsing and numeric->string formatting is now
locale-independent and always uses '.' as decimal marker. #1796
* oiiotool outputs are now written to temporary files, then atomically moved
to the specified filename at the end. This makes it safe for oiiotool
to "overwrite" a file (i.e. `oiiotool in.tif ... -o out.tif`) without
problematic situations where the file is truncated or overwritten
before the reading is complete. #1797
* Python bindings for ImageBuf.get_pixels and set_pixels fixed some bugs
when passed an ROI without a channel range specified. #1802
* More robust parsing of XMP metadata for unknown metadata names. #1816
* strutil.h now includes a to_string<> utility template. #1814
Release 1.8.6 (1 Nov 2017) -- compared to 1.8.5
-------------------------------------------------
* oiiotool: Improved logic for propagating the pixel data format through
multiple operations, especially for files with multiple subimages.
#1769
* ImageCache/TextureSystem: improved stats on how long we wait for
ImageInput mutexes. #1779
* Build: Fix build bug where if the makefile wrapper got CODECOV=0, it would
force a "Debug" build (required for code coverage tests) even though code
coverage is instructed to be off. (It would be fine if you didn't specify
CODECOV at all.) #1792
* Build: minor fixes for Windows build. #1793, #1794
* Developers: The ParamValue class has added get_int_indexed() and
get_float_indexed() methods. #1773
* Developers: array_view added begin(), end(), cbegin(), cend() methods,
and new constructors from pointer pairs and from std::array.
* Developers: Fixed build break in simd.h when AVX512VL is enabled. #1781
* Developers: fmath.h now defined OIIO_FMATH_H so other files can easily
detect if it has been included.
* Build: Fix broken build when Freetype was not found or disabled. #1800
* Python: fixed missing exposure of RATIONAL enum value. #1799
Release 1.8 (1.8.5 - 1 Oct 2017) -- compared to 1.7.x
----------------------------------------------
New minimum dependencies:
* **C++11** (should also build with C++14 and C++17)
* **Compilers**: gcc 4.8.2 - gcc 7, clang 3.3 - 5.0, or MSVS 2013 - 2017
* **Boost >= 1.53** (tested up through 1.65)
* **CMake >= 3.2.2** (tested up through 3.9)
* **OpenEXR >= 2.0** (recommended: 2.2)
* (optional) **Qt >= 5.6**
* (optional) **Python >= 2.7** (3.x is also ok)
**Changes to install layout**: fonts now get installed to
`PREFIX/share/fonts/OpenImageIO`, OIIO docs now get installed to
`PREFIX/share/doc/OpenImageIO`, and the Python module gets installed to
`PREFIX/lib/pythonMAJ.MIN/site-packages`. #1747#1760 (1.8.5)
Major new features and improvements:
* New oiiotool features:
* `--info:format=xml` format option requests what format the info
is printed. Current choices: `"text"`, `"xml"`. #1504 (1.8.0)
* `--info:verbose=1` verbose option make file info print full metadata,
but without needing to make other oiiotool operations verbose as would
happen with `--info -v`. #1504 (1.8.0)
* `--colormap` applies a color map based on the input values; the
map can be one of several named ones, or given explicitly with
numerical values. #1552 (1.8.1)
* `-i:type=...` lets you override the internal buffer type that will be
used for an input image. #1541 (1.8.1)
* `-i:ch=a,...` lets you restrict the input to only the listed channels.
This is semantically equivalent to following the input with a `--ch`
command, but by integrating into the input itself, it can sometimes
avoid using memory and I/O for unneeded channels. #1541 (1.8.1)
* `--echo STRING` prints the string to the console. This can contain
expressions! So you can do something like
oiiotool file.exr -echo "Size is {TOP.width}x{TOP.height}"
#1633 (1.8.3)
* `--eraseattrib REGEX` erases all metadata attributes from the top image
whose names match the regular expression. #1638 (1.8.3)
* `--text` takes new optional modifiers: `xalign=` (left, right, center)
and `yalign=` (baseline, top, bottom, center) to control how the text
is aligned to the (x,y) position specified, `shadow=` (default = 0)
than when nonzero controls the width of a "drop shadow" that makes the
text clearer when rendered on a background image of similar color.
#1646 (1.8.3)
* `--deepholdout` culls all samples that are farther away than the
opaque depth of a second holdout image. #1691 (1.8.4)
* New ImageBufAlgo functionality:
* `color_map()` applies a color map based on the input values; the
map can be one of several named ones, or given explicitly with
numerical values. #1552 (1.8.1)
* Added implementation of ImageBufAlgo::to_IplImage(). #1461 (1.7.9/1.8.1)
* `render_text()` has added parameters controlling text alignment and
drop shadows. #1646 (1.8.3)
* `deep_holdout()` culls all samples that are farther away than the
opaque depth of a second holdout image. #1691 (1.8.4)
* DICOM file format support (currently read-only). DICOM is the standard for
medical imaging data. Will only build if dependency "dcmtk" is found at
build time. #1534 (1.8.1)
* Experimental: The TextureSystem API has been extended to support batches
of texture lookups in a SIMD fashion. At present, only the new API was
added, a full implementation is in progress and may not be forthcoming
or reliable until 1.9. Even the API is experimental, and may change for
future releases. #1733 (1.8.5)
Public API changes:
* TypeDesc:
* Rational support: new 'semantic' hint RATIONAL and TypeDesc::Rational.
A rational is an int of aggregate VEC2 and hint RATIONAL, and should
be interpreted as val[0]/val[1]. #1698 (1.8.5)
* Added OIIO-scoped `static constexpr` versions of preconstructed
TypeDescs (e.g., `TypeFloat`). We are deprecating the ones that were
static data members of TypeDesc (e.g., TypeDesc::TypeFloat), they will
be removed in some future release. (1.8.5)
* ImageSpec:
* New `ImageSpec::serialize()` returns a string with a serialized version
of the contents of the ImageSpec. It may be text (human readable, like
is printed by `oiiotool -info -v`) or XML. #1504 (1.8.0)
* `ImageSpec` has a new constructor that accepts a `ROI` for image
dimensions and channels. #1646 (1.8.3)
* New `ImageSpec::channelspec()` retrieves the index of a named channel.
#1691 (1.8.4)
* New `ImageSpec::channelname(int)` safely retrieves the index of a named
channel. #1706 (1.8.5)
* ColorConig::createLookTransform() and createDisplayTransform() have been
extended to allow multiple key/value context pairs, by making them
comma-separated lists. The createColorProcessor() method has also been
extended to take context key/value pairs. #1542 (1.7.8, 1.8.0)
* `ImageBuf::read()` now has a variety that takes a channel range, allowing
you to populate an ImageBuf with a subset of channels in a file,
potentially saving memory and I/O for the unneeded channels. #1541 (1.8.1)
* Python: Fix unimplemented ImageBufAlgo.computePixelStats. #1596
(1.8.2/1.7.11)
* imageio.h: Fix incorrect declaration of declare_imageio_format().
#1609 (1.8.2/1.7.11)
* `ImageBuf::wrap_mode_from_string()` converts string wrap mode names
(such as "black") into `ImageBuf::WrapMode` enum values. #1615 (1.8.3)
* New `OIIO::getattribute()` queries:
* `"input_format_list"` and `"output_format_list"` return comma-separated
lists of all formats that support input and output, respectively.
#1577 (1.8.3)
* `"oiio:simd"` returns a comma-separated list of SIMD capabilities that
were enabled at build time, and `"hw:simd"` returns the list of
capabilities available on the currently running hardware. #1719 (1.8.5)
* `ImageBufAlgo::render_text()` API call has been overhauled, in addition
to new alignment and shadow aprameters, the color has changed from a raw
pointer to an `array_view<const float>` for better memory safety. Also,
it is now valid for the destination image to be uninitialized, in which
case it will be initialized to be just big enough for the text.
#1646 (1.8.3)
* DeepData:
* New `DeepData::opaque_z()` returns the depth value at which a pixel
becomes fully opaque. #1691 (1.8.4)
* New `DeepData::initialized()` and `allocated()` return whether the
DD is initialized and allocated, respectively. #1691 (1.8.4)
* `DeepData::split()` has been changed to return a `bool` indicating
whether any split occurred. #1691 (1.8.4)
* Remove some long-deprecated varieties of `ImageBufAlgo::colorconvert()`,
`ociolook()`, and `ociodisplay()`. #1695 (1.8.4)
* TypeDesc now allows specification of "rational" values, using a vec2i
(aggregate 2-vector of int) with a semantic hint of RATIONAL, i.e.,
`TypeDesc(INT, VEC2, RATIONAL)`, which is also aliased as
`TypeDesc::TypeRational`. The value is understood to be val[0]/val[1].
#1698 (1.8.5)
* ParamValueList::get_float will automatically convert rational values to
float. #1698 (1.8.5)
* The standard metadata "FramesPerSecond" has had its definition changed
from `float` to `rational`. Retrieving it as `float` should still work
as always. But apps and plugins that wish to treat it as a true rational
with no loss of precision are able to do so. This is only known to
directly affect the OpenEXR, GIF, and FFMPEG metadata. #1698 (1.8.5)
Fixes, minor enhancements, and performance improvements:
* oiiotool:
* `--chappend` resolves redundant channel names by using the subimage
name, if available. #1498 (1.8.0/1.7.8)
* `--mosaic` now gracefully handles the case of not having enough
images to completely fill the MxN matrix, with "left over" slots
black. #1501 (1.8.0/1.7.8)
* When command line arguments fail to parse properly, `oiiotool` will
exit with a non-zero shell status. #1540 (1.8.0)
* `--colorconvert`, `--ociodisplay`, and `--ociolook` can now take
multiple context key/value pairs (by allowing `key=` and `value=`
optional paramters be comma-separated lists). #1504 (1.8.0)
* Handle 'oiiotool --colorconvert X X' (transform from and to spaces that
are the same) without considering it an error. #1550 (1.8.0/1.7.8)
* Expression substitution now recognizes the following new metadata
names: MINCOLOR, MAXCOLOR, AVGCOLOR. An example use is to stretch
the value range of an image to fill the full [0-1] range:
oiiotool in.exr -subc {TOP.MINCOLOR} -divc {TOP.MAXCOLOR} -o out.exr
#1553 (1.8.1)
* `--fit:exact=1` use of the new `exact=1' option will perform the resize
to preserve exact aspect ratio and centering of the fit image to true
sub-pixel precision (at the possible risk of slight blurring,
especially of the edges), whereas the default (`exact=0`) will keep
the image sharper but round the size and offset to the nearest whole
pixel values. (1.8.1).
* `-i:type=...` optional modifier to `-i` forces a read of the input
file into a particular data type. #1541 (1.8.1)
* `-i:ch=...` optional modifier to `-i` specifies that only certain named
channels should be read from the file. Under extreme circumstances
when only a small subset of channels is needed from an image file with
many channels, this may improve speed and I/O. #1541 (1.8.1)
* Improved logic governing output data formats: non-cached inputs didn't
set default output data format correctly, and per-channel output
formats updated defaults when they shouldn't have. #1541 (1.8.1)
* `--diff` : in addition to the pixel coordinates and differences of the
biggest differing pixel, it now also prints the full values of all
channels of that pixel for both images. #1570 (1.8.1)
* `oiiotool -d` giving per-channel formats is no longer confused by
channel renaming with `--chnames`. #1563 (1.8.1/1.7.9)
* `--debug` nor prints the total runtime and peak memory use after each
individual op. #1583 (1.8.1)
* `-iconfig` not in all cases correctly propagate the input config
attribute to the file read. #1605 (1.8.2/1.7.11)
* Fixed `--crop`: it did not honor the `-a` flag to apply the crop to
all subimages. #1613 (1.8.2/1.7.11)
* In the case of runtime errors, `oiiotool` now echoes the entire command
line. This is helpful for debugging mangled oiiotool command lines
assembled by scripts. #1614 (1.8.3)
* Improved error reporting of file open errors when -iconfig is used.
#1626 (1.8.3/1.7.13)
* Expression evaluation now substitutes `FRAME_NUMBER` with the numeric
frame number for frame sequence wildcards, and `FRAME_NUMBER_PAD`
with the frame number 0-padded to the number of total digits specified
by the command line `--framepadding` argument. #1648 (1.8.3)
* `--resize` and `--resample` now have more intuitive behavior for images
where the display and pixel data windows are not the same, especially if
the data window had a nonzero origin (such as with crop or overscan).
#1667 (1.8.4/1.7.14)
* `--resample` has been extended to work for "deep" images. #1668
(1.8.4/1.7.14)
* `--deepmerge` now will give a useful error message when the image do
not have the same number of channels. #1675 (1.8.4/1.7.14)
* `--autocc` more gracefully handles unknown color spaces with a warning,
rather than a full error and termination. #1681 (1.8.4)
* `--resample` now takes an optional modifier `interp=0` to control
whether bilinear sample is used (default) or true closest-pixel point
sampling. #1694 (1.8.4)
* You can set rational metadata on the command line like this:
`oiiotool foo.exr --attrib:type=rational onehalf "50/100" -o rat.exr`
#1698 (1.8.5)
* `--fillholes` fixed a bug where, if asked to operate on an image with
nonzero origin (crop, overscan, shrink-wrap), it would incorrectly
move the pixels to the origin. #1768 (1.8.5)
* ImageBufAlgo:
* `channel_append()` resolves redundant channel names by using the
subimage name, if available. #1498 (1.8.0/1.7.8)
* `colorconvert()`, `ociodisplay()`, and `ociolook()` can now take
multiple context key/value pairs (by allowing they `context_key` and
`context_value` paramters be comma-separated lists). #1504 (1.8.0)
* `draw_rectangle()` (and `oiiotool --box`) wasn't drawing properly for
the degenerate case of a rectangle that takes up just one
pixel. #1601 (1.8.2)
* `resample()` has been extended to work for "deep" images.
#1668 (1.8.4/1.7.14)
* `deep_merge()` now will give a useful error message when the images do
not have the same number of channels. #1675 (1.8.4/1.7.14)
* `deep_merge()` performance has been greatly improved. #1739 (1.8.5)
* `resample()` fixed a subtle 1/2 pixel shift, now it more closely
aligns with `resize()`. #1694 (1.8.4)
* `fillholes_pushpull()` fixed a bug where, if asked to operate on an
image with nonzero origin (crop, overscan, shrink-wrap), it would
incorrectly move the pixels to the origin. #1768 (1.8.5)
* ImageBuf:
* Fix broken threads(n) method, which didn't correctly pass the right
number of threads along. #1622. (1.8.3/1.7.12)
* Copy constructor from another ImageBuf was previously broken for
IB's that wrap application buffers. #1665 (1.8.4/1.7.13)
* TextureSystem / ImageCache / maketx:
* `IC::get_image_info` (or `TS::get_texture_info`) queries for "channels"
on UDIM file patterns now succeed, returning the value for the first
matching file it finds. (N.B.: Relies on all textures within the same
UDIM set having the same nchannels.) #1502, #1519, #1530 (1.8.0/1.7.8)
* maketx: multiple simultaneous maketx process trying to create the same
texture will no longer clobber each other's output. #1525 (1.8.0/1.7.8)
* ImageCache: make robust to changes in autotile after opening and reading
from untiled files. #1566 (1.8.1/1.7.9)
* ImageCache: fix initialization bug that made the reported stats output
nonsensical in the numbers it gave for "redundant reads". #1567
(1.8.1/1.7.9)
* get_image_info queries of "displaywindow" and "datawindow" did not
correctly return a 'true' value when the data was found.
#1574 (1.8.1/1.7.9)
* maketx fix: two textures that had identical source pixels but differed
in whether they resized with "highlight compensation" incorrectly
ended up with identical hashes, and thus could be confused by the
TextureSystem at runtime into thinking they were duplicates. The hash
is now fixed. #1599 (1.8.2/1.7.11)
* Statistics no longer list as "BROKEN" files which were invalidated, or
files that were initialized with an ImageCacheFile but never opened.
#1655 (1.8.4)
* ImageCache::get_image_info() will now return a proper error (and not
hig an assertion) if asked for information about a subimage or MIP
level that does not exist in the file. #1672 (1.8.4/1.7.14)
* TextureSystem::get_texels fixes crashing behavior. #1669 (1.8.4/1.7.14)
* Big performance improvement on Windows with MSVC by removing certain
empty destructors in simd.h that was preventing MSVC from fully inlining
those classes. #1685 (1.8.4/1.7.15)
* maketx now supports `--colorconfig` option to explicitly point it to
an OpenColorIO config file, just like `oiiotool `--colorconfig`.
#1692 (1.8.4)
* Fix rare edge case crash in ImageCache. #1696 (1.8.4/1.7.15)
* Improved error messages for broken files. Specifically, it's much more
clear now when a file is broken because it's being rejected as a
texture because it's untiled or not MIP-mapped. #1751 (1.8.5)
* The maketx-generated metadata "oiio:SHA-1", "oiio:ConstantColor" and
"oiio:AverageColor" are ignored if the file has signs that it was not
directly generated by `maketx` or `oiiotool -otex` (specifically, if
it's not tiled, has no "textureformat" tag, or if its "software" tag
doesn't mention maketx or oiiotool). This helps for the case where a
maketx-generated file is loaded into PhotoShop (or otherwise altered),
saved with different pixel values but the old SHA-1, which would no
longer be valid and therefore cause the new file to be misidentified
as a duplicate texture even though it's not. #1762 (1.8.5)
* Bug fix to possible crashes when adding dither to tiled file output
(buffer size miscalculation). #1518 (1.8.0/1.7.8)
* Make sure that sRGB<->linear color transform still work (in the obvious
way) even when OpenColorIO is present but that its configuration for some
reason doesn't know about "sRGB" space. #1554 (1.8.1)
* Improved performance of input of many-channel files with differing
per-channel data formats. #1541 (1.8.1)
* `idiff` : in addition to the pixel coordinates and differences of the
biggest differing pixel, it now also prints the full values of all
channels of that pixel for both images. #1570 (1.8.1)
* ImageInput::read_tiles when only a channel subset is read, fixed case
with certain data sizes where the copy to user buffer got mangled.
#1595 (1.8.2/1.7.11)
* BMP:
* Add support for version 5 of the BMP format header. $1616 (1.8.3/1.7.12)
* FFMpeg/movies:
* "FramesPerSecond" metadata has had its type changed to rational.
#1709 (1.8.5)
* GIF:
* "FramesPerSecond" metadata has had its type changed to rational.
#1709 (1.8.5)
* IFF:
* Fix IFF output that didn't correctly save the "Author" and "Date"
metadata. #1549 (1.8.1/1.7.8)
* JPEG:
* Be more reslient to malformed Exif data blocks with bogus offsets
#1585 (1.8.1/1.7.10) and #1639 (1.8.3/1.7.13).
* When you ask the JPEG writer to output files with unsupported channel
counts (JFIF files only allow 1 or 3 channels), it will just silently
drop extra channels, rather than having a hard error. #1643 (1.8.3)
* OpenEXR:
* Fix global attribute "exr_threads" value, -1 should disable IlmImf's
thread pools as advertised. #1582 (1.8.1)
* Allow compression "none" for deep exr files. (1.8.2/1.7.11)
* Fixed input problem with sorting order of spectral alpha channels (RA,
GA, BA, or AR, AG, AB). #1674 (1.8./1.7.14)
* Can handle true rational metadata, including FramesPerSecond and
captureRate. #1698 (1.8.5)
* Fix problem with 2-channel images putting the channels in the wrong
order. #1717 (1.8.5/1.7.16)
* PNG: Better extraction of XMP from PNG files. #1689 (1.8.4)
* PSD:
* Support has been added for "cmyk", "multichannel", and "grayscale"
color modes. And support was fixed for rgb and grayscale 32 bit per
sample bit depth. #1641 (1.8.3/1.7.13)
* Fix issue for layer mask channels. #1714 (1.8.5)
* RAW:
* Fix possible crash when reading certain raw metadata. #1547 (1.7.8/1.8.0)
* The default value for missing "raw:use_camera_matrix" has been changed
to 1 (not 0) to better match default behavior of libraw/dcraw.
#1629 (1.8.3/1.7.13)
* Add support for selecting new demosaicing algorithms: "DMT" (mode 11)
and "AAHD" (mode 12). Renamed the "Modified AHD" to "AHD-Mod" to
simplify and match libraw terminology. Made matching of demosaicing
algorithms case-insensitive. #1629 (1.8.3/1.7.13)
* Support "ACES" color space for direct conversion while reading RAW
images (supported in libraw 0.18 or newer). #1626 (1.8.3/1.7.13)
* Add "raw:user_sat" configuration attribute to the reader.
#1666 (1.7.15/1.8.4)
* The pixels are now decoded (expensive) only when they are read, not
when the file is first opened. This makes raw reading much faster for
apps that are only interested in the metadata and not the pixel data.
#1741 (1.8.5)
* Unpack pixels when they are needed, not when the file is opened. This
makes it much faster to read RAW file only to extract the metadata,
if you don't need the pixel values. #1741 (1.8.5)
* RLA:
* Fix RLA reading and writing with certain channel orders and mixded data
formats. #1499 (1.8.0/1.7.8)
* TIFF:
* Fix to TIFF handling of certain unusual tags. #1547 (1.7.8/1.8.0)
* Now has a way to read raw pixel values from CMYK files, without
the automatic conversion to RGB (pass configuration attribute
"oiio:RawColor" set to nonzero). #1605 (1.8.2/1.7.11)
* Improved I/O of color separation images, particularly those with
custom InkSet attributes. #1658 (1.8.4/1.7.15)
* Fix typo that prevented correct reading of some Exif fields. #1625
(1.8.3/1.7.12)
* TIFF output omitted setting the "Make" and "Model" metadata tags.
#1642 (1.8.3/1.7.13)
* Images with fewer than 4 channels, but one of those channels was alpha,
were not correctly marking spec.alpha_channel. #1718 (1.8.5/1.7.16)
* The XPOSITION and YPOSITION tags are now interpreted as relative to
the RESOLUTIONUNIT, whereas before it was assumed to be measured in
pixels. We are confident that the new way is more in line with the
intent of the TIFF spec. #1631 (1.8.5)
* webp:
* Several new sanity checks prevent the webp reader from spending too
much I/O time and memory reading bogus files (malformed, corrupted,
or not a webp after all). #1640 (1.8.3/1.7.13)
* Nuke plugin: Fix txReader to properly restore saved MIP level knob value.
#1531 (1.8.0)
* Fixed several (so far unnoticed) buffer overruns and memory leaks.
#1591 (1.8.2)
* TIFF, JPEG, others: Improved reading Exif meatdata from XMP blocks, now it
does a better job of discerning the proper data types. #1627 (1.8.3/1.7.13)
* In several places, the formatting of date metadata has been changed to
have a leading zero rather than leading space for hours < 10, i.e.,
"02:00:00" rather than " 2:00:00". #1630 (1.8.3)
* Improve XMP parsing (for any format): for malformed XMP, still honor the
parts that could be parsed properly; recognize additinoal tags for
GPano (Google's Photo Sphere metadata schema) and camera raw (crs: prefix)
metadata; improve speed of XMP parsing. #1679 (1.8.4)
* Improved handling and color conversion of gamma-corrected images (DPX,
HDR, PNG, RLA, Targa) by supporting linearization correctly even in the
presence of OCIO configs that don't know about it. #1684 (1.8.4)
* Fixed static initialization order fiasco error involving interaction
between ColorConfig and Strutil. #1757 (1.8.5)
Build/test system improvements:
* **Changes to install layout**: fonts now get installed to
`prefix/share/fonts/OpenImageIO`, OIIO docs now get installed to
`prefix/share/doc/OpenImageIO`, and the Python module gets installed to
`prefix/lib/pythonMAJ.MIN/site-packages`. #1747#1760 (1.8.5)

now use C++11 std::regex rather than boost regex. #1620,#1644 (1.8.3)
* Support for clang-tidy using build time flags CLANG_TIDY=1,
CLANG_TIDY_ARGS=..., and optionally CLANG_TIDY_FIX=1. #1649 (1.8.4)
* Fix Windows warnings about SIMD types as function arguments
and about bool vs int. #1659 (1.8.4)
* Changed the way namespaces work. Instead of a 2-level namespace, make a
one-level namespace, and automatically embed the major and minor version
in it. (Can stll override the basename.) #1662 (1.8.4)
* Fixes to OSX rpath behavior of linked binaries. #1671
* Upgraded the local PugiXML (when not using an external system version)
to release 1.8.1. #1679 (1.8.4)

* Simplify CMake scripts by using GNUInstallDirs to set standard installation
paths. #1747 (1.8.5)
Developer goodies / internals:
* Sysutil::Term formatting now works properly in Windows (though is only
functional for Windows 10 or above). (1.8.0/1.7.8) #1527
* C++11 idioms:
* We now eschew BOOST_FOREACH, in favor of C++11 "range for". #1535
* We now use std::unique_ptr, no longer use boost::scoped_ptr or
boost::scoped_array. #1543 (1.8.0) #1586 (1.8.1)
* Instead of the various boost components, we now use `std::` versions of
unordered_map, unordered_set, shared_ptr, hash, bind. #1586 (1.8.1)
* Change deprecated C headers (such as `<ctype.h>`) to C++ (`<cctype>`).
#1649 (1.8.4)
* Use `std::vector<>::emplace_back()` where applicable. #1657 (1.8.4)
* Mark ImageInput/ImageOutput derived classes as 'final'. (1.8.5)

* Simplified array_view template to be 1D only. #1734 (1.8.5)
* atomic.h:
* Added atomic_min and atomic_max. #1661 (1.8.4)
* Added atomic_fetch_add for `std::atomic<float>` and double. #1661 (1.8.4)
* Assume std::atomic is available, remove all code that is only needed
for pre-C++11. #1661 (1.8.4)
* benchmark.h:
* New `Benchmarker` class utility for micro-benchmarking. #1577 (1.8.5)
* Moved time_trial, timed_thead_wedge, DoNotOptimize, clobber_all_memory
to benchmark.h. #1577 (1.8.5)

* Better exception safety for Filesystem::searchpath_find. #1680 (1.8.4/1.7.15)
* fmath.h:
* Fixed typo in fmath.h that made bitcast_to_float incorrect. #1543 (1.8.0)
* Templatize round_to_multiple() so it works with types other than `int`.
#1548 (1.8.0)
* `interpolate_linear()` utility linearly interpolates from a list of
evenly-spaced knots. #1552 (1.8.1)
* Slight reformulation of clamp() ensures sane results even with NaN
parameters. #1617 (1.8.3)
* Bug fixes to `ifloor()` and `floorfrac()`, which turned out to give
incorrect results for exact negative integer values. Also added
simd vector-based versions of `floorfrac`. #1766 (1.8.5)
* paramlist.h:
* ParamValueList has been refactored and now inherets from, rather than
containts, a `std::vector<ParamValue>`. This removes most of the
additional code from the class. #1677 (1.8.4)
* ParamValue new methods: `get<>()`, `get_int()`, `get_float()`,
`get_string()`, `get_ustring()` retrieve and convert. #1686 (1.8.4)
* ParamValueList new methods: `get_int()`, `get_float()`, `get_string()`,
`get_ustring()` search, retrieve, and convert (much like the
equivalent versions in ImageSpec did). #1686 (1.8.4)
* Remove the pointless typedefs `ImageIOParameter` and
`ImageIOParameterList` in favor of `ParamValue` and `ParamValueList`,
respectively. #1690 (1.8.4)
* platform.h:
* More `cpu_has_...()` tests for newer CPU capabilties. #1719 (1.8.5)
* Remove deprecated OIIO_NOTHROW macro, which should now simply be
C++11 `noexcept`. #1736 (1.8.5)
* strutil.h / Strutil:
* Add `Strutil::printf()` and `Strutil::fprintf()`, typesafe and
non-thread-jumbled replacements for C versions. #1579, #1656 (1.8.1, 1.8.4)
* `from_string<>` has been extended to 'unsigned int'. (1.8.3/1.7.13)
* `Strutil::parse_identifier_if` #1647 (1.8.3)
* safe_strcpy now takes a string_view, and more closely conforms to the
behavior of strncpy by filling in the extra space with 0 padding.
(1.8.5)
* simd.h:
* Add a matrix44 constructor from 16 floats. #1552 (1.8.1)

confusion with bit lengths of scalars. #1719 (1.8.5)
* Overhaul to support AVX-512 via vfloat16, vint16, vbool16 classes.
#1719 (1.8.5)
* load_mask, store_mask, and scatter/gather added for all types.
#1732 (1.8.5)
* Renamed `floori()` to `ifloor()` to match the analogous scalar function
in fmath.h. #1766 (1.8.5)
* strided_ptr.h: The `strided_ptr<>` template is now also templated on
the stride units -- the default is to measure strides in units of
sizeof(T), but it's possible to override and measure in bytes (the old
behavior). #1758 (1.8.5)
* thread.h:
* thread_pool class offers true persistent thread pool.
#1556, #1581 (1.8.1)
* Lots of C++ modernization of thread_group and spin_mutex. #1556 (1.8.1)
* Environment variable `OPENIMAGEIO_THREADS` can artificially raise or
lower the default number of threads (otherwise, it defaults to the
number of processor cores available). #1581 (1.8.1)
* timer.h: added timed_thread_widge() that benchmark code and prints
statistics about thread scaling. #1660 (1.8.4)
* typedesc.h:
* Modernized TypeDesc with C++11 constexpr where applicable. #1684 (1.8.4)
* New `TypeDesc::basevalues()` method. #1688 (1.8.4)
* unittest.h:
* Colored error messages and auto error return on completion. #1731 (1.8.5)
* *NEW* parallel.h:
* parallel_for, parallel_for_chunked, parallel_for_each offer simple
thread_pool-based parallel looping in 1 and 2 dimensions.
#1556, #1581 (1.8.1)
* Internal `OIIO::debugmsg()` call has been renamed to `OIIO::debug()`,
and setting env variable OPENIMAGEIO_DEBUG_FILE can redirect the debug
messages to a file. #1580 (1.8.1)
* Upgraded tinyformat to the latest master, also changed all the places
where we used TINYFORMAT_WRAP_FORMAT to use of C++11 variadic templates.
#1618 (1.8.3)
* *NEW* function_view.h : function_view<> is a very lightweight, non-owning,
generic callable object view. Cheaper than std::function, but the view
is not allowed to outlive the callable object it references. #1660 (1.8.4)
* Deprecate the pre-C++11 macros OIIO_CONSTEXPR, OIIO_CONSTEXPR_OR_CONST,
and OIIO_NOEXCEPT. #1678 (1.8.4)
Docs:
* Improve docs about deep IBA functions. (1.8.1)

* ImageCache and TextureSystem now have close(filename) and close_all()
methods, which for one file or all files will close the files and release
any open file handles (also unlocking write access to those files on
Windows), but without invalidating anything it knows about the ImageSpec
or any pixel tiles already read from the files, as would happen with a
call to the much more drastic invalidate() or invalidate_all(). #1950
Release 1.7.18 (1 May 2018) -- compared to 1.7.17
-------------------------------------------------
* Update to build against ffmpeg 4.0
Release 1.7.17 (1 Sep 2017) -- compared to 1.7.16

* Fix rare case TextureSystem crash. #1685
Release 1.7.14 (1 May 2017) -- compared to 1.7.13
-------------------------------------------------
* oiiotool expression substitution now recognizes FRAME_NUMBER and
FRAME_NUMBER_PAD. #1648
* oiiotool -resize and -resample now have more intuitive behavior for images
where the display and pixel data windows are not the same, especially if
the data window had a nonzero origin (such as with crop or overscan).
#1667
* oiiotool --resample and ImageBufAlgo::resample() have been extended to
work for "deep" images. #1668
* ImageCache::get_image_info() will now return a proper error (and not hit
an assertion) if asked for information about a subimage or MIP level that
does not exist in the file. #1672
* ImageBuf copy constructor from another ImageBuf was previously broken for
IB's that wrap application buffers. #1665
* TextureSystem::get_texels fixes crashing behavior. #1669
* Fixes to OSX rpath behavior of linked binaries. #1671
* OpenEXR file input: fixed problem with sorting order of spectral alpha
channels (RA, GA, BA, or AR, AG, AB). #1674
* ImageBufAlgo::deep_merge() (and oiiotool --deepmerge) now will give a
useful error message if you try to merge two deep images that do not have
the same number of channels. #1675
* ImageCache/TextureSystem statistics no longer list as "BROKEN" files which
were invalidated, or files that were initialized with an ImageCacheFile
but never opened. #1655
* Fix Windows warnings about SIMD types as function args, and about
int vs bool. #1659
Release 1.7.13 (1 Apr 2017) -- compared to 1.7.12
----------------------------------------------
* TIFF, JPEG, others: Improved reading Exif meatdata from XMP blocks, now it
does a better job of discerning the proper data types. #1627
* RAW: The default value for missing "raw:use_camera_matrix" has been changed
to 1 (not 0) to better match default behavior of libraw/dcraw. #1629

and "AAHD" (mode 12). Renamed the "Modified AHD" to "AHD-Mod" to
simplify and match libraw terminology. Made matching of demosaicing
algorithms case-insensitive. #1629
* RAW: Support "ACES" color space for direct conversion while reading RAW
images (supported in libraw 0.18 or newer). #1626
* oiiotool: Improved error reporting of file open errors when -iconfig is
used. #1626
* oiiotool `--echo STRING` prints the string to the console. This can contain
expressions! So you can do something like
oiiotool file.exr -echo "Size is {TOP.width}x{TOP.height}"
#1633
* JPEG: Be more reslient to malformed Exif data blocks with bogus offsets.
#1585, #1639
* TIFF output omitted setting the "Make" and "Model" metadata tags. #1642
* webp: Several new sanity checks prevent the webp reader from spending too
much I/O time and memory reading bogus files (malformed, corrupted,
or not a webp after all). #1640
* PSD: Support has been added for "cmyk", "multichannel", and "grayscale"
color modes. And support was fixed for rgb and grayscale 32 bit per
sample bit depth. #1641
Release 1.7.12 (1 Mar 2017) -- compared to 1.7.11
----------------------------------------------
* BMP: add support for version 5 headers. #1616
* TIFF: Fix typo that prevented correct reading of some Exif fields. #1625
* ImageBuf: Fix broken threads(n) method, which didn't correctly pass the
right number of threads along. #1622.

Release 1.7.11 (1 Feb 2017) -- compared to 1.7.10
----------------------------------------------
* maketx fix: two textures that had identical source pixels but differed
in whether they resized with "highlight compensation" incorrectly
ended up with identical hashes, and thus could be confused by the
TextureSystem at runtime into thinking they were duplicates. The hash
is now fixed. (1599)
* OpenEXR: Allow compression "none" for deep exr files.
* Fix unimplemented python ImageBufAlgo.computePixelStats. (1596)
* IBA::draw_rectangle (and oiiotool --box) wasn't drawing properly for
the degenerate case of a rectangle that takes up just one
pixel. (1601)
* Fixed several (so far unnoticed) buffer overruns and memory leaks. (1591)
* ImageInput::read_tiles when only a channel subset is read, fixed case
with certain data sizes where the copy to user buffer got mangled. (1595)
* oiiotool -iconfig fixed, did not in all cases correctly propagate the
input config attribute to the file read. (1605)
* TIFF: now has a way to read raw pixel values from CMYK files, without
the automatic conversion to RGB (pass configuration attribute
"oiio:RawColor" set to nonzero). (1605)
* imageio.h: Fix incorrect declaration of declare_imageio_format(). (1609)
* `oiiotool --crop` did not properly honor the `-a` flag and apply the crop
to all subimages. (1613)
Release 1.7.10 (1 Jan 2017) -- compared to 1.7.9
----------------------------------------------
* Fix "exr_threads" value, -1 should disable IlmImf's thread pools. #1582

* Docs: fix 'Building OIIO on Windows' link. #1590
Release 1.7.9 (1 Dec 2016) -- compared to 1.7.8
----------------------------------------------
* Make sure that sRGB<->linear color transform still work (in the obvious
way) even when OpenColorIO is present but that its configuration for some
reason doesn't know about "sRGB" space. #1554
* ImageCache: make robust to changes in autotile after opening and reading
from untiled files. #1566
* ImageCache: fix initialization bug that made the reported stats output
nonsensical in the numbers it gave for "redundant reads". #1567
* IC/TS get_image_info queries of "displaywindow" and "datawindow" did not
correctly return a 'true' value when the data was found. #1574
* oiiotool -d giving per-channel formats is no longer confused by channel
renaming with --chnames. #1563
* Added implementation of ImageBufAlgo::to_IplImage(). #1461
Release 1.7.8 (1 Nov 2016) -- compared to 1.7.7
----------------------------------------------
* Fix gcc warnings when compiling for AVX2. #1511
* Fix a variety of Windows warnings and breaks. #1512, #1523
* Added support for new API introduced with ffmpeg 3.1. #1515
* Improve oiiotool --mosaic, wasn't reliably clearing the blank spaces
for missing images.
* Smarter channel_append channel renaming: try to resolve redundant
channel names by using the subimage name, if available. #1498
* Texture: get_image_info queries for "channels" on UDIM file patterns
now succeeds, returning the value for the first matching file it finds.
(Relies on all textures within the same UDIM set having the same
nchannels.) #1502, #1519
* Bug fix to possible crashes when adding dither to tiled file output
(buffer size miscalculation). #1518
* maketx: multiple simultaneous maketx process trying to create the same
texture will no longer clobber each other's output. #1525
* Build no longer gets confused about include files from older installations
of OIIO elsewhere on the system. #1524
* Improvements in finding OpenJPEG. #1520
* Sysutil::Term formatting now works properly in Windows (though is only
functional for Windows 10 or above). #1527
* Fix RLA reading and writing with certain channel orders and mixded data
formats. #1499
* Improved finding of OCIO headers. #1528
* Better recognition of C++11 features in MSVS.
* Fix compile warnings with Clang 3.9. #1529

(like size_t). #1548
* Fix IFF output that didn't correctly save the "Author" and "Date"
metadata. #1549
* Handle 'oiiotool --colorconvert X X' (transform from and to spaces that
are the same) without considering it an error. #1550
Release 1.7 (1 Oct 2016) -- compared to 1.6.x
----------------------------------------------
Major new features and improvements:
* New oiiotool commands:
* `-otex` and `-oenv` allow oiiotool to directly output proper texture
maps, and it can now do everything that maketx can do. #1351 (1.7.2)
* `--line` can draw polylines into an image. #1319 (1.7.1)
* `--box` can draw a filled or unfilled box into an image. #1319 (1.7.1)
* `--laplacian` computes the Laplacian. #1332 (1.7.1)
* `--deep_merge` does a full merge/composite of deep images. #1388 (1.7.2)
* `-i` inputs a file. Options `autocc=`, `now=`, `info=` control aspects
of reading that one file. #1389 (1.7.2)
* `--dilate` and `--erode` perform the basic morphological operations
of dilation and erosion. #1486 (1.7.5)
* New ImageBufAlgo functions: render_point(), render_line(), render_box()
#1319 (1.7.1); laplacian() #1332 (1.7.2); copy() #1388 (1.7.2);
deep_merge() #1388,1393 (1.7.2); dilate() and erode() (1.7.5).
* UDIM support for textures: filenames like `"tex_<UDIM>.exr"` will
automatically be resolved to the correct UTIM tile based on the s,t
coordinates. #1426 (1.7.3)
* Behavior change: When reading files without explicit channel names,
single channel images now name their channel "Y" (no longer "A",
which was confusing to algorithms that treat alpha in special ways).
Similarly, 2-channel images name their channels "R" and "G". #1434 (1.7.3)
Public API changes:
* DeepData internals and API overhaul: struct internals hidden, now you
must use the API; DeepData declaration is now in deepdata.h, not in
imageio.h; DD methods now allow insertion and erasure of individual
samples. #1289 (1.7.0) New DeepData methods: split, sort, merge_overlaps,
merge_deep_pixels, occlusion_cull. #1388,1393 (1.7.2)
* imageio.h: Removed items deprecated since 1.4: a version of convert_types()
that took alpha and z channel indices (but never used them). #1291
* fmath.h: Removed safe_sqrtf, safe_acosf, fast_expf, which have been
deprecated since 1.5. (1.7.0) #1291
* Removed ImageBufAlgo::flipflop(), which was deprecated since 1.5 and
is now called rotate180. #1291 (1.7.0)
* Several varieties of ImageCache and TextureSystem getattribute methods
were noticed to not be properly declared 'const'. This was fixed.
#1300 (1.7.0/1.6.9)
* For API calls that are deprecated but not yet removed, we now mark
them with deprecated attributes for compilers that support it,
meaning that you will get compile warnings and explanations when you
use deprecated OIIO API functions. #1313,#1318 (1.7.1)
* ImageBuf::contains_roi() reveals whether an ROI is completely contained
in the data region of the IB. #1310 (1.7.1)
* TypeDesc::is_signed() return true of the TypeDesc returns a type that
can represent negative values. #1320
* Python: improve: reading with request for type UNKNOWN returns native
data in an unsigned char array. Also, requesting HALF returns the half
bits in an unsigned short array (since there is no 'half' type in Python).
#1362 (1.7.2/1.6.11)
* Deprecate ImageCache/TextureSystem clear() methods, which never did
anything useful. #1347 (1.7.3)
* ImageSpec::set_format() clears any per-channel format information. #1446
(1.7.4)
* OIIO::getattribute("library_list", ...) can retrieve a list of all the
dependent libraries used when OIIO was built. #1458 (1.7.5)
* simd::mask4 class has been renamed simd::bool4 (though the old name
is still typedef'ed to work for now). #1484 (1.7.5)
* Python bindings for ImageBuf.reset() now properly understands the
argument names and default values. #1492 (1.7.6)
Fixes, minor enhancements, and performance improvements:
* oiiotool:
* oiiotool --subimage now takes as an argument either the subimage
numeric index, or a subimage name. #1287 (1.7.0)
* oiiotool's image cache was smaller than intended because of typo.
(1.7.0/1.6.9)
* Allow command-line expression metadata names to contain ':'. #1321
(1.7.1/1.6.10)
* --info more clearly prints info about subimage formats. #1320 (1.7.1)
* --ch: when the channels were only renamed, not reordered, the
renaming didn't happen properly. #1326 (1.7.1/1.6.10)
* Improved error message propagation from the underlying IBA functions
and from errors encounered during --stats. #1338 (1.7.2)
* --dumpdata:empty=0 now does something for non-deep files: skips
reporting of pixels where all channels are black. Also fixed errors
for dumpdata of deep, but non-float, files. #1355 (1.7.2/1.6.11)
* '--attrib:type=t name value' lets you explicitly name the top of
the attribute you're seting. This helps for ambiguous cases, and also
lets you create aggregate types (such as 'matrix' or 'int[2]' --
the value can be a comma-separated list in those cases). #1351 (1.7.2)
* --fixnan can now take option "error", meaning that upon finding a
NaN, the program considers it an error (rather than fixing).
#1351 (1.7.2)
* -o now takes optional arguments that control the output of just that
one file, including :datatype=, :bits=, :dither=, :autocc=,
:autocrop=, :autotrim=, :separate=, :contig=. #1351 (1.7.2)
* --resize and --fit sped up by approximately 2x. #1372 (1.7.2)
* --runstats not tracks and reports max memory usage. #1385 (1.7.2)
* New --cache and --autotile options let you set the ImageCache size and
autotile options. #1385 (1.7.2)
* --native results in slightly different behavior: does not force float,
but still uses the ImageCache as backing if the native data type
is one of the types directly supported by IC. #1385 (1.7.2)
* --fixnan now works with deep images. #1397 (1.7.3)
* --stats when used with deep images, if it encounters any nonfinite
values, will print the location of a representative one. #1397 (1.7.3)
* --add, --sub, and --absdiff, when its two image operands have differing
number of channels, now try to do the "correct" thing and have the
result have the larger number of channels, treating any "missing"
channels in either input as if they were 0-valued. #1402 (1.7.3)
* --attrib:type-timecode lets you set timecodes in "human-readable" form:
oiiotool in.exr -attrib:type=timecode TimeCode 11:34:03:00 -o out.exr
#1415 (1.7.3)
* -info -v will print timecodes in human-readable form. #1415 (1.7.3)
* Bug fix: --fullsize didn't work properly when followed by --attrib.
#1418 (1.7.3/1.6.14)
* Easily understandable warnings for common mistakes: no output specified,
an image that's modified but never output, or when -autocc causes
output to be a data format that overrides a previous -d directive.
#1419 (1.7.3)
* --origin, --croptofull, and --trim all do their thing to all subimages,
if the image at the top of the stack has multiple subimages.
#1440 (1.7.3)
* --crop operates on all subimages if either the -a flag was used, or
if the specific optinoal override `--crop:allsubimages=1` is used.
#1440 (1.7.3)
* --trim will trim all subimages to the same region, containing the
union of all nonzero pixels in all subimages. #1440 (1.7.3)
* --help now prints all of the dependent libraries for individual
formats. #1458 (1.7.5)
* Bug fix: make sure to propagate per-channel formats from input
to output. #1491 (1.7.6)
* -o:all=n will output all images currently on the stack, and the
filename argument will be assumed to be a pattern containing a %d,
which will be substituted with the index of the image (beginning with
n). For example, to take a multi-image TIFF and extract all the
subimages separately,
oiiotool multi.tif -sisplit -o:all=1 sub%04d.tif
will output the subimges as sub0001.tif, sub0002.tif, and so on.
#1494 (1.7.6)
* --mosaic MxN would fail mysteriously if the number of images on the
stack was less then M*N. This has been fixed to handle too-few images
gracefully and just leave blank spaces as needed. #1501 (1.7.7)
* ImageBuf:
* ImageBuf::iterator performance is improved -- roughly cutting in half
the overhead of iterating over pixels. #1308 (1.7.1/1.6.10)
* ImageBuf reads from disk have been improved substantially (in some
cases cutting read time in half) in many cases. #1328 (1.7.1)
* ImageBuf::copy_pixels() has been sped up. #1358 (1.7.2)
* ImageBufAlgo:
* The varieties of add(), sub(), mul(), and div() that take an
image operand and a per-channel constant operand have all been
modified to work properly for "deep" images. #1297 (1.7.0/1.6.10)
* mad() is sped up significantly (10x) for the common case of float
images already stored in memory (not cached). #1310 (1.6.1)
* render_point(), render_line(), render_box() can be used to render
points, lines, and boxes into an image. #1319 (1.7.1)
* channels(): when the channels were only renamed, not reordered,
the renaming didn't happen properly. #1326 (1.7.1/1.6.10)
* computePixelStats: Improved numerical accuracy to avoid getting
NaN values from imprecision. #1333 (1.7.2/1.6.11)
* laplacian() computes the laplacian of an image. #1332 (1.7.2)
* fixNonFinite() takes a new option: NONFINITE_ERROR, which will
return an error if nonfinite values are encountered. #1351 (1.7.2)
* convolve() and unsharp_mask() have been sped up by about 35% for
common cases. #1357 (1.7.2)
* IBA::resize sped up by approximately 2x. #1372 (1.7.2)
* IBA::fixNonFinite() now works with deep images. #1397 (1.7.3)
* dilate() and erode() perform basic morphological operations.
#1486 (1.7.5)
* ImageCache / TextureSystem:
* Less unnecessary pausing after read errors when falure_retries == 0.
#1336 (1.7.2/1.6.11)
* Texture: slight improvement in texture sharpness. #1369 (1.7.2/1.6.11)
* New statistics related to redundant tile reads. #1417 (1.7.3)
* TextureSystem option "flip_t", if nonzero, will flip the vertical
direction of all texture lookups. Use this for renderers that adhere
to the convention that the t=0 texture coordinate is the visible
"bottom" of the texture. #1428 (1.7.3) #1462 (1.7.5)
* UDIM support for textures: filenames like `"tex_<UDIM>.exr"` will
automatically be resolved to the correct UTIM tile based on the
s,t coordinates. #1426 (1.7.3)
* Avoid repeated broken texture error messages. #1423 (1.7.3)
* New IC/TS attribute: "max_errors_per_file" limits how many error
messages are printed for each file. #1423 (1.7.3)
* Improved statistics: for the "top 3" stats, print the top 3 that aren't
broken. Also print a count & list of broken/invalid files. #1433
(1.7.3/1.6.15)
* Add ability to retrieve various per-file statistics. #1438 (1.7.3/1.6.15)
* IC will clamp the max_open_files to the maximum allowed by the
system, so you can no longer crash a program by incorrectly
setting this limit too high. #1457 (1.7.5)
* IC/TS statistics now report separately the total size of images
referenced, in terms of in-cache data size, as well as on-disk
size (the latter may be compressed). #1481 (1.7.5)
* maketx:
* maketx -u now remakes the file if command line arguments or OIIO
version changes, even if the files' dates appear to match.
#1281 (1.7.0)
* Remove long-obsolete and non-functional command line options: --new,
--old, --hash. #1351 (1.7.2)
* iinfo:
* More clearly prints info about subimage formats. #1320 (1.7.1)
* Print timecodes in human-readable form. #1415 (1.7.3)
* ImageOutput: fix cases with native data but non-contiguous strides.
#1416 (1.7.3/1.6.15)
* Cineon:
* Improved deduction/setting of color space info. #1466 (1.7.5)
* GIF:
* GIF reader failed to set spec full_width, full_height. #1348
(1.7.2/1.6.11)
* JPEG:
* Fix bad memory access crash when reading specific JPEG files that were
written without their comment field including a null character to
end the string. #1365 (1.7.2/1.6.11)
* Change in behavior writing JPEG files when XResolution & YResolution
are not provided, but a PixelAspectRatio is requested. Previously, we
obeyed the JPEG/JFIF spec exactly, but it turns out that popular apps
including PhotoShop and Nuke use the field differently than the spec
dictates. So now we conform to how these apps work, rather than to
the letter of the spec. #1412 (1.7.3/1.6.15)
* OpenEXR:
* Fix broken multipart output when parts had different pixel data
types. #1306,#1316 (1.7.1/1.6.10)
* Improved error reporting for bad tile reads. #1338 (1.7.2/1.6.11)
* Fix errors reading tiles for mixed-format EXR files. #1352 (1.7.2/1.6.11)
* The global OIIO::attribute("exr_threads") has been modified so that 0
means to use full available hardware, -1 disables the OpenEXR
thread pool and execute in the caller thread. #1381 (1.7.2)
* When writing EXR, double check that there are no repeated channel
names, and if so, rename them so the data is not lost (since the
underlying libIlmImf will silently drop channels with repeated
names). #1435 (1.7.3)
* More robust detected of when OpenEXR is tiled (for weird files).
#1441 (1.7.3/1.6.15) (and a fix in #1448/1.7.4)
* Fixed minor bug with OpenEXR output with correctly setting
PixelAspectRatio based on the "XResolution" and "YResolution"
attributes. #1453 (Fixes#1214) (1.7.4/1.6.16)
* Fix setting "chromaticity" metadata in EXR files. #1487 (1.7.5)
* When writing OpenEXR, accept compression requests with quality numbers
appended to the compression algorithm name, such as "dwaa:200" to mean
dwaa compression with a dwaCompressionLevel set to 200. #1493 (1.7.6)
* PNG:
* Per the PNG spec, name 2-channel images Y,A. #1435 (1.7.3)
* Enforce that alpha premultiplication on output MUST consider alpha
to be the last channel of 2 or 4 channel images, no other cases
(as dictated by the PNG spec). #1435 (1.7.3)
* PNM:
* Fixed byte swapping when reading 16 but PNM files. #1352 (1.7.2/1.6.11)
* RAW:
* Changes to how we instruct libraw to process images when reading:
Now, by default, auto-bright adjustment is off, camera white
balance is on, and maximum threshoding is set to 0. There are
"open with config" overrides for all of these, for anybody who
doesn't like the default. #1490 (1.7.6)
* RLA:
* Fixes for both reading and writing of RLA images that are cropped
(i.e., data window is a subset of display window). #1224 (1.7.0/1.6.10)
* TIFF:
* When outputting a TIFF file, a special attribute "tiff:half", if
set to nonzero, will enable writing of 16-bit float pixel data
(obviously, only if the spec.format is HALF). #1283 (1.7.0)
* TIFF input: erase redundant IPTC:Caption and IPTC:OriginatingProgram
if they are identical to existing ImageDescription and Software
metadata, respectively. (1.7.0/1.6.9)
* Output: "tiff:zipquality" attribute controls time-vs-quality for
ZIP compression (1-9, defualt 6, higher means more compression).
#1295 (1.7.1)
* Fix typo that made TIFF files incorrectly name color space metadata
"oiio::ColorSpace" instead of "oiio:ColorSpace". #1394 (1.7.2)
* More robust handling of non-zero origin of full/display window.
#1414 (1.6.14/1.7.3)
* Video formats:
* The ffmpeg-based reader had a variety of fixes. #1288 (1.7.0)
* Support for reading 10-bit and 12-bit movies. #1430 (1.7.5)
* Improved accuracy of "lanczos3" filter; speed up blackman-harris filter.
#1379 (1.7.2)
* Speed up linear<->sRGB color conversions (as used by any of the IBA color
conversion functions as well as oiiotool --colorconvert and friends),
approximately doubling the speed when no OpenColorIO config is found.
#1383 (1.7.2)
* ImageInput::create() and ImageOutput::create() will now gracefully
handle unexpected exceptions inside an ImageInput or ImageOutput
constructor -- return an error rather than crashing. #1456 (1.7.4/1.6.16)
* Nuke txWriter adds UI to let you choose which type of texture you are
building (ordinary 2D texture, latlong env map, etc). #1488 (1.7.6)
Build/test system improvements:
* Default build is now C++11! #1344 (1.7.2) You can still (for now) build
for C++03 using 'make USE_CPP11=0' or 'cmake -DOIIO_BUID_CPP11=0', but
some time soon we will be C++11 minimum.
* Fix build break against Boost 1.60. #1299,#1300 (1.7.0/1.6.9/1.5.23)
* filesystem_test now much more comprehensively tests the contents of
Filesystem. #1302 (1.7.0)
* fmath_test adds benchmarks for various data conversions. #1305 (1.7.0)
* Travis: add DEBUG builds to the matrix to fix any warnings or failures
that only show up for DEBUG builds. #1309 (1.7.1/1.6.10)
* Fix build issues on some platforms for SHA1.h, by adding proper include
of `<climits>`. #1298,#1311,#1312 (1.7.1/1.6.10)
* Cleanup of include logic in simd.h that fixed build problems for gcc < 4.4.
#1314 (1.7.1/1.6.10)
* Fix build breaks for certain 32 bit platforms. #1315,#1322 (1.7.1/1.6.10)
* imagespeed_test can not specify the data conversion type for reads,
can optionally allow skipping the IB iteration tests, and can set the
IC tile cache size. #1323 (1.7.1)
* Fix build breaks for gcc 6. #1339 (1.7.2/1.6.11) #1436 (1.7.3/1.6.15)
* Fix errors in finding the correct locaiton of pugixml.hpp when using
USE_EXTERNAL_PUGIXML=1. #1339 (1.7.2/1.6.11)
* Rewrite of FindOpenEXR.cmake. Solves many problems and is simpler.
No more FindIlmbase.cmake at all. #1346 (1.7.2/1.6.11)
* 'make CODECOV=1; make CODECOV=1 test' can build and test in a way that
provides a code coverage report. #1356 (1.7.2)
* Fix Filesystem::open() issues with UTF-8 filenames on MinGW.
#1353,#1357 (1.7.2/1.6.11)
* Allow build against a wider range of ffmpeg versions. #1359 (1.7.2)
* Build correctly against FFMPEG 3.0. #1374 (1.7.2)
* If found, libjpeg-turbo is used rather than libjpeg; this gives about a
2x speed improvement for reading & writing JPEG files. #1390 (1.7.2/1.6.13)
* USE_CPP11=... and USE_CPP14=... are the build flags for both the Make
wrapper and the CMake scripts. (Before, it was confusing to have USE_CPP11
for make but OIIO_BUILD_CPP11 for CMake. Now they are one.) #1391 (1.7.2)
* Improved LINKSTATIC=1, now mostly works. #1395 (1.7.3)
* Big CMake refactor, got rid of redundancies. #1395 (1.7.3)
* Remove old embedded Ptex, now must find Ptex externally. Also modified
the build scripts to correctly handle newer versions of Ptex. #1400
(1.7.3/1.6.13)
* Got Appveyor building OIIO. This is a continuous integration service
much like Travis, but it's for Windows. Hopefully this means that it will
be much harder for us to make changes that inadvertently break the build
on Windows. #1399 (1.7.3)
* Make FindOpenEXR.cmake more robust when the version number is embedded
in the library name. #1401 (1.7.3/1.6.15)
* Clear up some inconsistencies in the CMake files and the Makefile wrapper:
the flag to compile with libc++ is now always called USE_LIBCPLUSPLUS,
not sometimes OIIO_BUILD_LIBCPLUSPLUS. #1404 (1.7.3)
* Overhaul OpenCV dependency finding and make it work with OpenCV 3.x.
#1409 (1.7.3/1.6.13)
* Allow custom JPEG_PATH to hint location of JPEG library. #1411
(1.7.3/1.6.13)
* Windows UTF-8 filename safety fixes. #1420 (1.7.3/1.6.14)
* Various Windows compilation & warning fixes. #1443 (1.7.3/1.6.15)
* Now builds correctly against OpenJPEG 2.x, it previously only supported
OpenJPEG 1.x. #1452 (Fixes#957, #1449) (1.7.4/1.6.16)
* Fix Filesystem::searchpath_find on Windows with UTF-8 paths.
#1469 (1.7.51.6.17)
* Improved the way OpenEXR installations are found. #1464 (1.7.5)
Developer goodies / internals:
* thread.h has had all the atomic operations split into a separate atomic.h.
#1443 (1.7.3)
* atomic.h: add atomic and, or, and xor. #1417 (1.7.2/1.6.14);
* parallel_image has been improved in several ways: can choose split
direction; raised minimum chunk size to prevent thread fan-out for
images too small to benefit; uses the calling thread as part of the
pool. #1303 (1.7.0)
* timer.h: DoNotOptimize() and clobber_all_memory() help to disable certain
optimizations that would interfere with micro-benchmarks. #1305 (1.7.0)
* simd.h improvements: select(); round(); float4::store(half*),
int4::store(unsigned short*), int4::store(unsigned char*). #1305 (1.7.0)
Define insert, extract, and ^ (xor), and ~ (bit complement) for mask4,
and add ~ for int4. #1331 (1.7.2); madd, msub, nmadd, nmsub, rint,
andnot #1377 (1.7.2); exp, log #1384 (1.7.2); simd::float3 is like float4,
but only loads and stores 3 components, it's a good Vec3f replacement (but
padded) #1473 (1.7.5); matrix44 4x4 matrix class #1473 (1.7.5);
mask4 renamed to bool4, and addition of float8, int8, bool8 classes
for 8-wide AVX/AVX2 SIMD #1484 (1.7.5).
* fmath.h: convert_types has new special cases that vastly speed up
float <-> uint16, uint8, and half buffer conversions #1305 (1.7.0);
ifloor (1.7.2); SIMD versions of fast_log2, fast_log, fast_exp2,
fast_exp, fast_pow_pos #1384 (1.7.2); fix sign of expm1 for small
arguments #1482 (1.7.5); added fast_log1p #1483 (1.75).
* Fix pesky precision discrepancy in internal convert_type<> that used
slightly different math when converting one value at a time, versus
converting whole arrays. #1350 (1.7.2)
* thread.h: add mutex_pool #1425 (1.7.3/1.6.15)
* compute_test: new unit test can be used to benchmark computation
times. #1310 (1.7.1)
* filesystem.h: Filesystem::file_size() returns file size in bytes;
Filesystem::read_bytes() reads the first n (or all) bytes from a file
into a buffer. #1451 (1.7.4/1.6.16)
* strutil.h: Strutil::extract_from_list_string is more flixible by
allowing the vals list to start empty, in which case it will add as
many values as it finds rather than only replacing existing
values #1319 (1.7.1); Strutil::replace #1422 (1.7.3/1.6.15);
utf_to_unicode now takes a string_view rather than a std::string&
#1450 (1.7.4); add Strutil::base64_encode() #1450 (1.7.4).
* sysutil.h: Sysutil::getenv() safely gets an env variable as a string_view
#1451 (1.7.4/1.6.16); terminal_columns() now has a correct implementation
on Windows #1460 (1.7.5); max_open_files() retrieves the maximum number
of files the process may open simultaneously #1457 (1.7.5).
* platform.h: better distinguishing beteen Apple and Generic clang,
separately set OIIO_CLANG_VERSION and OIIO_APPLE_CLANG_VERSION. Also change
OIIO_GNUC_VERSION to 0 for clang, only nonzero for true gcc. #1380 (1.7.2)
* ImageCache: remove unused shadow matrix fields, save space. #1424 (1.7.3)
* Many documentation files (such as README, CHANGES, LICENSE, CREDITS,
and INSTALL) have been changed from plain text to MarkDown. #1442 (1.7.3)
* Sysutil::Term class makes it easy to use color output on the terminal.
#1479 (1.7.5)

------------------------------------------------
* Fix EXR tile logic for OpenEXR 1.x (fixes a break introduced in 1.6.15,
is not an issue for exr 2.x). #1448
* Now builds correctly against OpenJPEG 2.x, it previously only supported
OpenJPEG 1.x. #1452 (Fixes#957, #1449)
* New utility functions: Sysutil::getenv(), Filesystem::file_size(),
FileSystem::read_bytes(). #1451
* Fixed minor bug with OpenEXR output with correctly setting
PixelAspectRatio based on the "XResolution" and "YResolution"
attributes. #1453 (Fixes#1214)
* Gracefully handle unexpected exceptions inside an ImageInput or
ImageOutput constructor -- return an error rather than crashing.
#1456
Release 1.6.15 (released 1 Jul 2016 -- compared to 1.6.14)
------------------------------------------------
* Improved statistics: for the "top 3" stats, print the top 3 that aren't
broken. Also print a count & list of broken/invalid files. #1433
* Change in behavior writing JPEG files when XResolution & YResolution
are not provided, but a PixelAspectRatio is requested. Previously, we
obeyed the JPEG/JFIF spec exactly, but it turns out that popular apps
including PhotoShop and Nuke use the field differently than the spec
dictates. So now we conform to how these apps work, rather than to
the letter of the spec. #1412
* IC/TS: add ability to retrieve various per-file statistics. #1438
* Windows UTF-8 filename safety fixes. #1420

in the library name. #1401
* Fix build breaks for gcc 6. #1339 (1.7.2/1.6.11) #1436
* More robust detected of when OpenEXR is tiled (for weird files). #1441

* strutil.h: added replace(). #1422
* thread.h: added mutex_pool. #1425
Release 1.6.14 (released 1 Jun 2016 -- compared to 1.6.13)
------------------------------------------------
* More robust handling of TIFF I/O when non-zero origin of full/display
window. (#1414)
* oiiotool --fullsize didn't work properly when followed by --attrib. (#1418)
Release 1.6.13 (released 1 May 2016 -- compared to 1.6.12)
------------------------------------------------
* Use libjpeg-turbo if found. It's a drop-in replacement for libjpeg, but
is around 2x faster. #1390
* Fix some Windows compiler warnings and errors.
* Remove old embedded Ptex, now must find Ptex externally. Also modified
the build scripts to correctly handle newer versions of Ptex. #1400
* Overhaul OpenCV dependency finding and make it work with OpenCV 3.x. #1409
* Allow custom JPEG_PATH to hint location of JPEG library. #1411
Release 1.6.12 (released 1 Apr 2016 -- compared to 1.6.11)
------------------------------------------------
* Build correctly against FFMPEG 3.0. #1374
* The global OIIO::attribute("exr_threads") has been modified so that 0
means to use full available hardware, -1 disables the OpenEXR thread
pool and execute in the caller thread. #1381
* Thread-pool counts initialized to hardware_concurrency, not
physical_concurrency (i.e., they will include hyperthread cores by
default). #1378
* oiiotool --autocc bug fixed.
* Miscellaneous improvements to simd.h ported from master.
* Fix typo that made TIFF files incorrectly name color space metadata
"oiio::ColorSpace" instead of "oiio:ColorSpace". #1394
Release 1.6.11 (released 1 Mar 2016 -- compared to 1.6.10)
------------------------------------------------
* Fix potential of IBA::computePixelStats (including oiiotool --stats)
to end up with NaNs due to numerical imprecision. #1333
* Less unnecessary pausing after read errors when falure_retries == 0.
#1336
* Fix errors in finding the correct locaiton of pugixml.hpp when using
USE_EXTERNAL_PUGIXML=1. #1339
* Fix build breaks for gcc 6. #1339
* GIF reader failed to set spec full_width, full_height. #1348
* PNM: Fixed byte swapping when reading 16 but PNM files. #1352
* OpenEXR: Improved error reporting for bad tile reads. #1338
* OpenEXR: Fix errors reading tiles for mixed-format EXR files. #1352
* oiiotool --dumpdata:empty=0 now does something for non-deep files: skips
reporting of pixels where all channels are black. Also fixed errors
for dumpdata of deep, but non-float, files. #1355
* Fix Filesystem::open() issues with UTF-8 filenames on MinGW. #1353
* Rewrite of FindOpenEXR.cmake. Solves many problems and is simpler.
No more FindIlmbase.cmake at all. #1346
* Fix build break for older gcc < 4.4 that didn't have immintrin.h.
* Fix bad memory access crash when reading specific JPEG files that were
written without their comment field including a null character to
end the string. #1365
* The ffmpeg-based reader had a variety of fixes. #1288
* Python: improve: reading with request for type UNKNOWN returns native
data in an unsigned char array. Also, requesting HALF returns the half
bits in an unsigned short array (since there is no 'half' type in Python).
#1362
* Texture: slight improvement in texture sharpness. #1369
* Update webp testsuite references for new webp version.
Release 1.6.10 (released 1 Feb 2016 -- compared to 1.6.9)
------------------------------------------------
* ImageBufAlgo add, sub, mul, and div, for the varieties that combine
an image with a (per-channel) constant, now work for "deep" images.
#1257
* ImageBuf::iterator performance is improved -- roughly cutting in half
the overhead of iterating over pixels. #1308
* OpenEXR: Fix broken multipart output when parts had different pixel
data types. #1306,#1316
* Allow oiiotool command-line expression metadata names to contain ':'.
* Fix oiiotool --ch (or IBA::channels) when the channels were only renamed,
not reordered, the renaming didn't happen properly. #1326
* Fixes for both reading and writing of RLA images that are cropped
(i.e., data window is a subset of display window). #1224
* Fix build issues on some platforms for SHA1.h, by adding proper include
of `<climits>`. #1298,#1311,#1312
* Cleanup of include logic in simd.h that fixed build problems for gcc < 4.4.
#1314
* Fix build breaks for certain 32 bit platforms. #1315,#1322
Release 1.6.9 (released 5 Jan 2016 -- compared to 1.6.8)
------------------------------------------------
* Several varieties of ImageCache and TextureSystem getattribute methods
were noticed to not be properly declared 'const'. This was fixed.
#1300 (1.6.9)
* Fix build break against Boost 1.60. #1299,#1300 (1.6.9/1.5.23)
* The Python bindings for ImageCache was overhauled after several
of the methods were found to be horribly broken. #1300 (1.6.9)
* oiiotool --subimage now allows a subimage name as argument, as well
as the numeric index. #1271,#1287 (1.6.9)
* TIFF input: erase redundant IPTC:Caption and IPTC:OriginatingProgram
if they are identical to existing ImageDescription and Software metadata,
respectively. (1.6.9)
* Fix oiiotool image cache smaller than intended because of typo. (1.6.9)
Release 1.6 (1.6.8 released Dec 21, 2015 -- compared to 1.5.x)
----------------------------------------------
Major new features and improvements:
* New oiiotool functionality:
* Expression evaluation/substitution on the oiiotool command line.
Anything enclosed in braces { } in a command line argument will be
substituted by the evaluation of the enclosed expression. Expressions
may be numbers, simple arithmetic (like 'expr+expr'), or retrieving
image metadata from named images or images on the stack.
Please see the PDF documentation, Section 12.1 for details and
examples.
* --absdiff, --absdiffc compute the absolute difference (abs(A-B)) of
two images, or between an image and a constant color. #1029 (1.6.0)
* --abs computes the absolute value of an image. #1029 (1.6.0)
* --div, divc divide one image by another (pixel by pixel), or divides
the pixels of an image by a constant color. #1029 (1.6.0)
* --addc, --subc, --mulc, --powc are the new names for --cadd, --csub,
--cmul, and --cpow. The old ones will continue to work but are
considered depcrected. #1030 (1.6.0)
* --pattern supports new patterns: "fill" makes a solid, vertical or
horizontal gradient, or four-corner interpolated image (just like
the --fill commmand) (1.6.0); "noise" can generate uniform, gaussian,
or salt & pepper noise (1.6.2).
* --fill, in addition to taking optional parameter color=... to give a
solid color for the fill region, now also takes top=...:bottom=... to
make a vertical gradient, left=...:right=... to make a horizontal
gradient, and topleft=...:topright=...:bottomleft=...:bottomright=...
to make a 4-corner gradient. (1.6.0)
* --noise adds noise to the current image: additive uniform or gaussian
noise, or making "salt & pepper" noise. (1.6.2)
* --trim crops the image to the minimal rectangle containing all
the non-0 pixels. (1.6.3)
* --autocc : when turned on, automatic color conversion of input files
into a scene_linear space, and conversion to an appropriate space
and pixel type upon output. It infers the color spaces based on
metadata and filenames (looking for OCIO-recognized color space names
as substrings of the filenames). #1120 (1.6.3)
* --mad takes three image arguments, multiplies the first two and then
adds the third to it. #1125 (1.6.3)
* --invert computes the color inverse (1-value) for color channels.
#1125 (1.6.3)
* --colorconfig allows you to specify a custom OCIO configuration file
(rather than strictly relying on the $OCIO env variable). #1129 (1.6.3)
* --deepen converts flat images to "deep". #1130 (1.6.3)
* -n (no saved output) performs all calculations (including timing and
stats) but does not write any output files to disk. #1134 (1.6.3)
* --debug prints debugging information, this is now separate from
-v which just makes more verbose (non-debugging) output. #1134 (1.6.3)
* --pixelaspect rescales the image to have the given pixel aspect
ratio. #1146 (1.6.5)
* --ociofiletransform() implements OpenColorIO "file" transforms.
#1213 (1.6.5)
* New ImageBufAlgo functions:
* absdiff() computes the absolute difference (abs(A-B)) of two images,
or between an image and a constant color. #1029 (1.6.0)
* abs() computes the absolute value of an image. #1029 (1.6.0)
* div() divides one image by another (pixel by pixel), or divides all
the pixels of an image by a constant color. #1029 (1.6.0)
* fill() has been extended with new varieties that take 2 colors (making
a vertical gradient) and 4 colors (one for each ROI corner, for a
bilinearly interpolated gradient). (1.6.0)
* noise() injects noise into an image -- uniform, gaussian/normal,
or salt & pepper noise. (1.6.2)
* mad() multiplies the first two arguments and then adds the third to
it. #1125 (1.6.3)
* invert() computes 1-val. #1125 (1.6.3)
* deepen() turns a flat RGBA (and optional Z) image into a "deep"
image. #1130 (1.6.3)
* ociofiletransform() implements OpenColorIO "file" transforms.
#1213 (1.6.5)
* Some open source fonts are now distributed with OIIO (DroidSans,
DroidSans-Bold, DroidSerif, DroidSerif-Bold, DroidSerif-Italic,
DroidSerif-BoldItalic, and DroidSansMono), and so those are always
available to ImageBufAlgo::render_text() and oiiotool --text, on all
platforms and even if you don't have any other installed fonts on
your system. DroidSans is now the default font. #1132 (1.6.3)
* GIF output support (including writing animated GIF images, just write it
as a multi-subimage file). For example, this works:
oiiotool foo*.jpg -siappendall -attrib FramesPerSecond 10.0 -o anim.gif
#1193 (1.6.4)
Public API changes:
* TypeDesc:
* New helper methods: is_array(), is_unsized_array(), is_sized_array().
#1136 (1.6.3)
* New constructor and fromstring of a string_view, in addition to
the old versions that took char*. #1159 (1.6.4/1.5.16)
* New aggregate type: MATRIX33. #1265,#1267 (1.6.6)
* ImageSpec:
* ImageSpec::metadata_val() is now static, rather than simply const,
since it doesn't need access to *this at all. #1063 (1.6.1)
* Added a new variety of find_attribute that takes a temporary
ImageIOParameter as scratch space. The advantage of this call is
that it can retrieve items from the named ImageSpec fields, such
as "width", "full_x", etc. Also, the get_int_attribute,
get_float_attribute, and get_string_attribute can now retrieve
these fixed fields as well. #1063 (1.6.1)
* ImageInput & ImageOutput:
* New ImageOutput::supports() tags: supports("alpha") should be true
for image formats that support an alpha channel, supports("nchannels")
should be true for output formats that support an arbitrary number
of output channels. (1.6.2/1.5.13)
* ImageInput and ImageOutput supports() method has been changed to accept
a string_view (rather than a const std::string&), and return an int
(rather than a bool). (1.6.2)
* ImageInput and ImageOutput have added destroy() static
methods. They are just wrappers around 'delete', but can help you
to ensure that II and IO objects are deleted on the same side of a
DLL boundary as where they were created. (Helps with using OIIO
from DLL-based plugins on Windows.) (1.6.3)
* New ImageInput query: "procedural" -- returns 1 if the ImageInput may
not correspond to an actual file. #1154 (1.6.4/1.5.16)
* ImageInput and ImageOutput's error() method is changed from protected
to public, making it easier for an app to set an error on a reader
or writer. (1.6.4)
* ImageOutput::copy_to_image_buffer is a helper function that
generalizes the existing copy_tile_to_image_buffer, but for any
rectangle. #1193 (1.6.4)
* ImageInput::read_image() variant that takes a channel range to
read just a subset of the channels present. #1222 (1.6.5)
* ImageInput and ImageOutput now have new method threads(n) that sets
the thread "fan-out" for the ImageInput or ImageOutput individually,
overriding any global attribute("threads"). #1259 (1.6.6)
* ImageBuf:
* Add make_writeable(), which forces ImageCache-backed read-only
ImageBuf to read into locally allocated pixels so they can be
subsequently altered. #1087 (1.6.2)
* ImageBuf::Iterator has added set_deep_samples() and set_deep_value()
methods. (1.6.3)
* ImageBuf::set_pixels() now provides a way to set an arbitrary
rectancle of an ImageBuf from raw values. #1167 (1.6.4)
* ImageBuf::get_pixels() now has a variety that takes an ROI to
describe the rectangle of pixels being requested. #1167 (1.6.4)
* ImageBuf now has new method threads(n) that sets the thread
"fan-out" for the ImageInput or ImageOutput individually,
overriding any global attribute("threads"). #1259 (1.6.6)
* ImageCache/TextureSystem:
* Clarified in the docs that TextureSystem::get_texture_info and
ImageCache::get_image_info "exists" queries should return true, and
place in *data the value 1 or 0 depending on whether the image exists
and can be read. (1.6.0/1.5.10)
* Added handle-based versions of TextureSystem get_texture_info(),
get_imagespec(), imagespec(), and get_texels(), in addition to the
existing name-based versions of those methods. Note that
texture(), environment(), and texture3d() already had both
name-based and handle-based varieties. #1057 (1.6.1) #1083 (1.6.2)
* Add create_thread_info() and destroy_thread_info() methods that
allow an app to manage the per-thread records needed by the IC.
#1080 (1.6.2)
* Added ImageCache get_perthread_info() and get_image_handle() to
return opaque perthread and file handle pointers, much like
TextureSystem already had, and added handle-based versions of
get_image_info(), get_imagespec(), imagespec(), get_pixels(), and
get_tile(), in addition to the existing name-based versions of
those methods. #1057 (1.6.1)
* ImageCache get_tile and get_pixels have new varieties that let you
request channel begin/end range. This allows you to control which
channel ranges are in the cache, and thus be much more efficient
with cache storage when only a few channels are needed from a file
with many channels. #1226 (1.6.5)
* ImageBufAlgo:
* New ImageBufAlgo functions: abs, absdiff, div, fill, noise, mad,
invert, deepen, ociofiletransform.
* nchannels() now takes an 'nthreads' parameters, just like all the
other ImageBufAlgo functions. #1261 (1.6.6)
* Python bindings:
* Added previously-M.I.A. ImageSpec::erase_attribute(). #1063 (1.6.1)
* ImageSpec.set_channel_formats() now works when the channel
type lists are either TypeDesc, in addition to the existing support
for BASETYPE. #1113 (1.6.3/1.5.13)
* Added Python bindings for DeepData and deep reads (ImageInput) and
writes (ImageOutput), as well as additional DeepData and ImageBuf
methods to fully match the C++ API. #1113#1122 (1.6.3/1.5.13)
* ImageBuf.set_pixels, and ImageBuf.get_pixels with ROI. #1167,1179 (1.6.4)
* Change Python ImageOutput bindings to simplify the write_* methods.
They no longer take both a TypeDesc and an array; it can figure out
the type from the array itself. Also get rid of the stride parameters,
which weren't useful in a Python context. #1184 (1.6.4)
* ImageBufAlgo colorconvert, ociolook, and ociodisplay now take an
optional string colorconfig argument. #1187 (1.6.4)
* Fix missing Python bindings for global OIIO::getattribute(). #1290
(1.6.8)
* The ColorConfig wrapper for OCIO functionality has been extended to
parse color names from filename strings, and to report the recommended
pixel data type for a color space. #1129 (1.6.3)
* C++11 definitions: oiioversion.h defines OIIO_BUILD_CPP11 as nonzero
if OIIO itself was built in C++11 (or later) mode, and platform.h
defines OIIO_USING_CPP11 as nonzero if at this moment C++11 (or
later) mode is detected. Note that these can differ if one set of
compiler flags was used to build OIIO, and a different set is used to
build a project that uses OIIO headers. #1148 (1.6.4)
* Renamed the "fps" standard metadata to "FramesPerSecond. #1193 (1.6.4)
* Removed deprecated header "string_ref.h" (use string_view.h). (1.6.1)
* oiioversion.h: Renamed the namespace macros OIIO_NAMESPACE_ENTER/EXIT to
OIIO_NAMESPACE_BEGIN/END, and roll the braces into it. #1196 (1.6.4)
* array_view.h: Refactor array_view to be more in line with what is slated
for C++17, in particular it is now templated on Rank and so can be a view
to a multi-dimensional array. Also change array_view_strided to have
strides measured in units of sizeof(T), not bytes (to keep with C++17).
This also adds coordinate.h to give definitions for the offset<>,
bounds<>, and bounds_iterator<> templates used by array_view. #1205
(1.6.4)
* Add top-level OIIO::get_int_attribute(), get_float_attribute(), and
get_string_attribute() helpers, similar to how they work in many
of the classes. #1283 (1.6.7)
Fixes, minor enhancements, and performance improvements:
* oiiotool
* Bug fix for frame sequences -- could crash in Windows. #1060 (1.6.1)
* Gracefully handle requests to save an image with more channels than
the output file format can handle. Instead of being a fatal error,
now it's just a warning, and extra channels are dropped. It tries to
to find R, G, B, and A channels, saving them. If those names are
not found, it just saves the first 3 (or 4) channels. #1058 (1.6.1)
* Improve error messages when files can't be read. It is now easier
to to distinguish files that don't exist from those that are an
unknown format from those that are corrupted or have read
errors. #1065 (1.6.1)
* Flag errors properly when -d specifies an unknown data format name.
#1077 (1.6.2/1.5.13)
* oiiotool numeric wildcard improvement: allow more digits to match.
#1082 (1.6.2/1.5.13)
* Bug fix: input file data format didn't always end up in the output.
(1.6.3)
* --channels bugs were fixed when dealing with "deep" images. (1.6.3)
* All the color space conversion operations run much faster now,
since the underlying IBA::colorconvert() has been parallelized. (1.6.3)
* --crop logic bug fixed in cases where the crop region was the same
size as the original pixel data window. #1128 (1.6.3)
* oiiotool now gives proper error messages when asked to perform
unsupported operations on deep images. (1.6.3)
* Bug fix: --frames incorrectly overrode explicit frame sequence
wildcards on the command line. #1133 (1.6.3)
* --crop, --trim, and --autotrim have been extended to work on
"deep" images. #1137 (1.6.3)
* For "procedural" ImageInputs, don't give "file doesn't exist"
errors. (1.6.4)
* Suppress output/copying of "textureformat" metadata inherited from
input if it's not plausibly still a valid texture (i.e., if it's
no longer tiled or MIPmapped). #1206 (1.6.4)
* oiiotool's full help message lists all supported formats. #1210 (1.6.5)
* oiiotool --help prints a briefer help screen. Use --help -v for
the full-detail help. #1214 (1.6.5)
* Bug fix in --fit when the image didn't need to be resized.
#1227 (1.6.5/1.5.21)
* Bug fix in --ch for "deep" files when the channel reordering is
the same as it already was. #1286 (1.6.7)
* ImageBufAlgo:
* compare() (and therefore oiiotool -diff and idiff) did not notice
image differences when the pixels that differed had NaN or NaN or
Inf values! Now it is right. #1109 (1.6.3/1.5.13)
* channels() bugs were fixed when dealing with "deep" images. (1.6.3)
* colorconvert() has been parallelized, and thus on most systems will
now run much faster. (1.6.3)
* render_text() handles UTF-8 input. #1121 (1.6.3)
* colorconvert(), ociodisplay(), and ociolook() have new varities that
accept an optional ColorConfig, rather than having no choice but to
construct a new one internally. (1.6.3)
* nonempty_region() and crop() have been extended to handle "deep"
images. #1137 (1.6.3)
* Fix bug in fft() -- was not always zeroing out the imaginary channel.
#1171 (1.6.4/1.5.17)
* Fixed uninitialized variable bugs with rangecompress() and
rangeexpand() when using luma. #1180 (1.6.4)
* The lanczos3, radial-lanczos, and catrom filters have been change
from fixed-width to fully scalable. This fixes artifacts that
occur when using them as upsizing filters. #1228,#1232 (1.6.5/1.5.21)
* maketx, TextureSystem, and ImageCache:
* TextureSystem/IC now directly stores uint16 and half pixel data in
the cache rather than converting internally to float for tile storage,
thus effectively doubling the cache capacity for files of those
formats. (1.6.3)
* Fix broken bicubic texture sampling with non-power-of-two sized
tiles. #1035 (1.6.0/1.5.10)
* maketx: when the source image was a crop (data window != display
window), and the sharpening filters were used, it would
incorrectly issue an "unknown filter name" error. #1059 (1.6.1/1.5.12)
* maketx: Flag errors properly when -d specifies an unknown data
format name. #1077 (1.5.13)
* maketx now writes to a temporary file, then moving it to the final
requested output filename only when the write completed without
error. This prevents situations where maketx crashes or is killed
and leaves behind a file that looks correct but is actually
corrupted or truncated. #1072 (1.6.2/1.5.13)
* TextureSystem bug fix that occasionally resulted in NaN in the
alpha channel result when looking up from 3-channel images. #1108
(1.6.3/1.5.13)
* maketx --runstats prints runtime staticstics (deprecating --stats).
#1152 (1.6.4)
* Fixed trilinear MIPmap texture lookups that gave invalid alpha fill.
#1163 (1.6.4/1.5.16)
* The lanczos3, radial-lanczos, and catrom filters have been change
from fixed-width to fully scalable. This fixes artifacts that
occur when using them as upsizing filters. #1228,#1232 (1.6.5)
* Texture cache memory efficiency is much better for the special case
of accessing just a few channels from a texture file with large
numbers of channels. #1226 (1.6.5)
* Eliminate spurious ImageCache invalidation just because the shared
cache is requested again. #1157 (1.6.4/1.5.16)
* Statistics output also shows all the option setting values. #1226 (1.6.5)
* Data copy error in ImageCache::get_pixels for partial-channel-set
copies. #1246 (1.6.5)
* maketx -u now remakes the file if command line arguments or OIIO
version changes, even if the files' dates appear to match.
#1281 (1.6.8)
* GIF:
* Write support! #1193 (1.6.4)
* On input, renamed "fps" metadata to "FramesPerSecond". #1193 (1.6.4)
* IFF:
* Fix botched output of 16 bit uncompressed data. #1234 (1.6.5/1.5.21)
* Make "rle" compression the default. #1234 (1.6.5/1.5.21)
* JPEG:
* Now properly read/write xdensity and ydensity (what OIIO and TIFF
call "XResolution" and "YResolution" and, therefore,
"PixelAspectRatio". #1042#1066 (1.6.0, 1.6.1)
* Support JPEG files encoded as CMYK (by converting to RGB upon read)
#1044 (1.6.1)
* Fix misdeclared supports() which would make the JPEG plugin appear
to not support exif or iptc. #1192 (1.6.4)
* JPEG-2000:
* Fix handling of un-premultiplied alpha (which is dictated by the
JPEG-2000 spec). (1.6.3)
* Fix reading of YUV-encoded files. (1.6.3)
* Read and write the ICC profile, if present. (1.6.3)
* Handle all bit depth precisions properly (previously only 8, 10,
12, and 16 were right). (1.6.3)
* Set the full/display window correctly. (1.6.3)
* Deal with differing per-channel data windows and sampling rates. (1.6.3)
* OpenEXR:
* Improved handling of density and aspect ratio. #1042 (1.6.0)
* Fix read_deep_tiles() error when not starting at the image origin.
#1040 (1.6.0/1.5.10)
* Fix output of multi-part exr file when some parts are tiled and
others aren't. #1040 (1.6.0/1.5.10)
* write_tile() with AutoStride calculated the wrong default strides
for "edge" tiles when the image width or length was not an integer
multiple of the tile size. Also clarified the PDF and imageio.h
docs in how they explain strides for this case. #1055 (1.6.1/1.5.12)
* Fix bugs in reading deep OpenEXR images with mixed channel types.
#1113 (1.6.3/1.5.13)
* OpenEXR output supports("deepdata") now correctly returns 'true'.
#1238 (1.6.5/1.5.21)
* A separate global OIIO::attribute("exr_threads") sets the thread pool
size for OpenEXR's libIlmImf, independent of the OIIO thread fan-out
attribute OIIO::attribute("threads"). #1244 (1.6.5)
* Correctly read and write Matrix33 and double (scalar, 2d, 3d, m33, m44)
metadata. #1265,#1267 (1.6.6)
* Recognize AR/AG/AB channel names in addition to the old RA/RG/RB
#1277 (1.6.6)
* PNG:
* Writing PNG files now honors the PixelAspectRatio metadata.
#1142 (1.6.3)
* PFM:
* PFM (float extension of PNM) was incorrectly flipped top to bottom.
Now fixed. #1230 (1.6.5)
* PSD:
* Better error handling for files lacking "global layer mask info"
or "additional layer info". #1147 (1.6.4/1.5.18)
* Additional PSD signatures for global additional layer info.
#1147 (1.6.4/1.5.18)
* Better error handling when dealing with an empty layer mask.
#1147 (1.6.4/1.5.18)
* TIFF:
* Improved handling of density and aspect ratio. #1042 (1.6.0)
* Improved proper handling of the interplay between "XResolution",
"YResolution", and "PixelAspectRatio". #1042 (1.6.0)
* TIFF output: recognize special "tiff:write_exif" metadata, which when
present and set to 0, will skip writing the Exif directory into the
TIFF file. This can be helpful when you expect the resulting TIFF
file to be read with very old versions of libtiff. #1185 (1.6.4/1.5.18)
* Correct read and write of JPEG-compressed TIFF. #1207 (1.6.4)
* Correct support for reading LAB, LOG, YCbCr, subsampled chroma.
#1207 (1.6.4)
* Make robust to strange TIFF files that have unexpected MIP
level-to-MIP level changes in planarconfig, photometric, palette,
extrasamples, etc. #1220,1221 (1.6.5/1.5.20)
* Support output of 2, 4, 10, and 12 bit unsigned ints into TIFF files.
#1216 (1.6.5)
* Make TIFF reading more robust to certain subimage-to-subimage
changes that were thought to be invariant. #1221 (1.6.5)
* CMYK is properly read and written. Upon read, CMYK is auto-converted
to RGB (and the "tiff:ColorSpace" metadata is set to "CMYK"). For
output, if "tiff:ColorSpace" metadata is set and nonzero, the RGB
passed in will be auto-converted to CMYK upon writing.
#1233#1245 (1.6.5)
* Recognize Exif tags in the main directory, not only the special
Exif directory. #1250 (1.6.5)
* Fix bug in read_scanlines when reading TIFF files with UNassociated
alpha and unusual ystride values. #1278 (1.6.6)
* ImageBuf iterator constructors with 0-size ranges or ROIs have been
fixed to look like they are immediately done(). #1141 (1.6.3)
* Fix bug in internal convert_image() that could corrupt certain image
copying of non-contiguous data layouts. #1144 (1.6.3)
* Also search for OIIO plugins in [DY]LD_LIBRARY_PATH. #1153 (1.6.4/1.5.16)
* Nuke plugin: don't crash with NULL Knob* in TxReaderFormat::setMipLabels.
#1212 (1.6.5/1.5.20)
* idiff -q results in quiet mode -- output nothing for success, only
minimal errors to stderr for failure. #1231 (1.6.5)
Build/test system improvements:
* Python plugin is now build as a cmake "module" rather than "library",
which fixes some things on OSX. #1043 (1.6.0/1.5.10)
* Various build fixes for Windows. #1052#1054 (1.6.1)
* New CMake build-time option to specify the default plugin search path.
#1056 (1.6.1/1.5.12)
* Fix build breaks for very old versions of Ilmbase (1.6 and earlier)
that lack a definition of V4f used by our simd.h. #1048 (1.6.1/1.5.11)
* Fix signed/unsigned warning on 32 bit platforms in jpeginput.cpp.
#1049 (1.6.1/1.5.11)
* New CMake build-time option to specify the default plugin search path.
#1056 (1.6.1/1.5.12)
* Fix gcc 5.0 compiler warning in PtexHalf.cpp. (1.6.1/1.5.12)
* Remove dependency of OpenSSL by default. #1086 (1.6.2/1.5.13)
* Fix warnings when compiling with C++11. (1.6.3/1.5.13)
* Dont link Python framework on OSX. #1099 (1.6.3/1.5.13)
* Changed the way testtex warps the image to give faux perspective to
test texture mapping. (1.6.3)
* Build-time USE_SIMD=... has been changed from accepting a single tag to
a comma-separated list of feature options. So you can, for example, do
make USE_SIMD=avx,f16c ... (1.6.3)
* make USE_NINJA=1 causes CMake to build Ninja build files instead of
Makefiles (they execute much faster, espectially for incremental builds).
#1158 (1.6.4)
* PSD & JPEG plugins fixes for Win32 compilation. #1150 (1.6.4/1.5.16)
* Fix Nuke plugin build files to not do anything if USE_NUKE=0.
#1156 (1.6.4/1.5.16)
* Builds now produce much less console output by default (use VERBOSE=1
to get all the details, most of which is only useful when debugging
broken builds). #1162 (1.6.4)
* Fix support for older ffmpeg version on Ubuntu 14.04. #1168 (1.6.4/1.5.17)
* Build-time fixes for Nocona CPUs that have SSE3 without SSSE3.
#1175 (1.6.4/1.5.17)
* ustring internals fixes for gcc 5.x changs to std::string ABI. #1176 (1.6.4)
* Fixes for clean build with clang 3.6. #1182,1183 (1.6.4)
* Fix signed/unsigned comparison error. #1186 (1.6.4)
* Top-level Makefile option USE_OPENCV=0 to turn off even searching for
OpenCV components. #1194 (1.6.4/1.5.18)
* If a system-installed (external) PTex implementation is found, use
it. Only use the "bundled" version if no other is found. Also add a
top-level USE_PTEX=0 that will skip PTex support, even if the library
is found. #1195,1197 (1.6.4)
* Fix compiler warnings about int vs size_t mismatches. 1199 (1.6.4)
* Improve C++11 and C++14 readiness. #1200
* Fix build break with certain new versions of libraw. #1204 (1.6.4/1.5.19)
* Fix build warnings for new Apple tools release that upgrades the standard
clang release. #1218 (1.6.5/1.5.20)
* When compiling in C++11 mode, std::unordered_map, mutex,
recursive_mutex, lock_guard, bind, ref, cref, thread, shared_ptr will
be used rather than boost equivalents, and our own thread_group and
intrusive_ptr are now used rather than the boost equivalents. We
believe that this completely removes all Boost headers and types from
the OIIO public APIs when in C++11 mode. (Though internals still use
Boost in some cases.) #1262#1266 (1.6.6)
* We are now set up to use Travis-CI (https://travis-ci.org) for continuous
integration / automatic builds of all merges and pull requests.
#1268, #1269, #1273 (1.6.6)
* Don't install fonts if USE_FREETYPE is disabled. #1275 (1.6.6)
* Use ccache for builds when detected and safe (unless USE_CCACHE=0).
#1274,#1285 (1.6.7)
* Failed tests now print their non-matching text output to the console
when doing 'make test'. This makes it much easier to spot most errors.
#1284 (1.6.7)
Developer goodies / internals:
* Strutil additions: parse_until, parse_nested (1.6.1), repeat
(#1272/1.6.6/1.5.21).
* Give Strutil::parse_string an option to not strip surrounding quotes.
(1.6.4)
* Made TypeDesc::equivalent accept comparisons of arrays of unspecified
length with ones of definite length. #1072 (1.6.2/1.5.13)
* Add Filesystem::rename() utility. #1070 (1.6.2/1.5.13)
* New SIMD methods: insert<>, xyz0, vreduce_add, dot, dot3, vdot, vdot3,
AxBxCxDx, blend0not (1.6.2)
* array_view enhancements that let you initialize an `array_view<const float>`
from a const `std::vector<float>&`. #1084 (1.6.2/1.5.14)
* hash.h contains several new hashes in namespaces 'OIIO::xxhash' and
'OIIO::farmhash'. Also, Strutil::strhash now uses farmhash rather than
the Jenkins one-at-a-time hash, bringing big speed improvements
(including ustring creation). Beware that the strhash value returned
will be different than they were before. #1090 (1.6.3)
* fmath: safe_fast_pow improves the precision of its results for
special cases of pow(x,1) and pow(x,2). #1094 (1.6.3/1.5.13)
* Added TypeDesc::TypeHalf(). #1113 (1.6.3/1.5.13)
* thread.h: our atomic types have had their API adjusted somewhat to
more closely conform to C++11's std::atomic. (1.6.3)
* ustring's internals and underlying hash table have been overhauled,
yielding much higher performance, especially when many threads are
simultaneously creating ustrings. (1.6.3)
* ROI improvement: make intersection & union robust to uninitialized ROIs
as arguments. (1.6.3)
* osdep.h is deprecated. Use platform.h instead. (1.6.3)
* The DISPATCH_TYPES utility macros used internally by IBA have been
improved, and in particular the DISPATCH_COMMON_TYPES now handle ALL
types ("uncommon" ones are silently converted to float). (1.6.3)
* platform.h moves the endian functions into the OIIO namespace. (1.6.3)
* platform.h adds functions for runtime query of CPU capabilities. (1.6.3)
* simd.h: float4 and int4 can now construct and load from unsigned short*,
short*, unsigned char*, char*, and 'half'. (1.6.3)
* Strutil::utf8_to_unicode (1.6.3)
* Filesystem::current_path(). #1124 (1.6.3/1.5.21)
* Filesystem enumerate_file_sequence and scan_for_matching_filenames
have been modified to clear their result vectors rather than simply
assume they are empty. #1124 (1.6.3)
* oiiotool internals have been refactored to be class-oriented and move
a lot of boilerplate repeated in each op to be part of the base
class. #1127 (1.6.3)
* timer.h: Timer and ScopedTimer have changed slightly. This isn't used
in any public OIIO APIs, but may affect 3rd party programs that like
to use OIIO's timer.h for convenience. #1201 (1.6.4/1.5.19)
* dassert.h: added OIIO_STATIC_ASSERT macros for static
assertion. Doesn't affect existing OIIO apps since they are new
additions, but feel free to use them! #1202 (1.6.4/1.5.19)
* New unit test for imagecache. #1246 (1.6.5)
* Sysutil::hardware_concurrency() and physical_concurrency(). #1263
(1.6.6/1.5.21)

* Fix build warnings for new Apple tools release that upgrades the standard
clang release. #1218
* Make TIFF reader robust to strange TIFF files that have unexpected MIP

--------------------------------------------------
* Fix compile warnings on some platforms/compilers.

* TIFF output: recognize special "tiff:write_exif" metadata, which when
present and set to 0, will skip writing the Exif directory into the TIFF
file. This can be helpful when you expect the resulting TIFF file to be
read with very old versions of libtiff. #1185
* Top-level Makefile option USE_OPENCV=0 to turn off even searching for
OpenCV components. #1194

---------------------------------------------------
* PNG writes now honor PixelAspectRatio attribute.
* Build fixes for Visual Studio 2010
* PSD & JPEG plugins fixes for Win32 compilation.
* Also search for OIIO plugins in [DY]LD_LIBRARY_PATH.
* Give Strutil::parse_string an option to not strip surrounding quotes.
* Fix Nuke plugin build files to not do anything if USE_NUKE=0
* New ImageInput query: "procedural" -- returns 1 if the ImageInput may
not correspond to an actual file.
* TypeDesc has a new constructor and fromstring of a string_view, in
addition to the old versions that took char*.
* Eliminate spurious ImageCache invalidation just because the shared
cache is requested again.
* Fixed trilinear MIPmap texture lookups that gave invalid alpha fill.
* Filesystem: sequence matching should clear results arrays upon start.
Release 1.5.15 (11 May 2015) -- compared to 1.5.14)
---------------------------------------------------
* Bug fix with IBA::channels() with deep data with UINT channels.
* Fix TypeDesc compatibility with OSL.
* Misc WIN32 / VS2010 fixes.
* Fix incorrect logic in convert_image with certain channel types and
strides.
Release 1.5.14 (14 April 2015) -- compared to 1.5.13)
----------------------------------------------
* Added Python bindings for DeepData and deep reads (ImageInput) and
writes (ImageOutput).
* Improve IBA::compare() (and therefore oiiotool -diff and idiff) when
the images being compared have NaN or Inf values.
* TextureSystem bug fix that occasionally resulted in NaN in the alpha
channel result when looking up from 3-channel images.
* Fix IBA::channels() bugs when dealing with "deep" images.
* Fix bugs in reading deep OpenEXR images with mixed channel types.
* fmath: safe_fast_pow improves the precision of its results for
special cases of pow(x,1) and pow(x,2).

Release 1.5.13 (10 Mar 2015) -- compared to 1.5.12)
----------------------------------------------
* oiiotool: Bug fix for frame sequences -- could crash in Windows.
* New ImageOutput::supports() tags: supports("alpha") should be true for
image formats that support an alpha channel, supports("nchannels") should
be true for output formats that support an arbitrary number of output
channels.
* oiiotool: Gracefully handle requests to save an image with more channels
than the output file format can handle. Instead of being a fatal error,
now it's just a warning, and extra channels are dropped. It tries to
to find R, G, B, and A channels, saving them. If those names are
not found, it just saves the first 3 (or 4) channels.
* Improved handling of "PixelAspectRatio" for JPEG, TIFF, and OpenEXR.
* oiiotool: Improve error messages when files can't be read. It is now
easier to to distinguish files that don't exist from those that
are an unknown format from those that are corrupted or have read
errors.
* maketx now writes to a temporary file, then moving it to the final
requested output filename only when the write completed without error.
This prevents situations where maketx crashes or is killed and leaves
behind a file that looks correct but is actually corrupted or
truncated.
* Python: added previously-M.I.A. ImageSpec.erase_attribute().
* Add Filesystem::rename() utility.
* Made TypeDesc::equivalent accept comparisons of arrays of unspecified
length with ones of definite length.
* oiiotool & maketx have improved error message when unknown data format
names are requested with "-d".
* oiiotool numeric wildcard improvement: allow more digits to match.
* Remove dependency of OpenSSL by default.
Release 1.5.12 (11 Feb 2015) -- compared to 1.5.11)
----------------------------------------------
* Various build fixes for Windows.
* New CMake build-time option to specify the default plugin search path.
(1.5.12)
* OpenEXR: fixed write_tile() with AutoStride calculated the wrong
default strides for "edge" tiles when the image width or length was
not an integer multiple of the tile size. Also clarified the PDF and
imageio.h docs in how they explain strides for this case. (1.5.12)
* maketx: when the source image was a crop (data window != display window),
and the sharpening filters were used, it would incorrectly issue an
"unknown filter name" error. (1.5.12)
* Fix gcc 5.0 compiler warning in PtexHalf.cpp. (1.5.12)
Release 1.5.11 (28 Jan 2015) -- compared to 1.5.10)
----------------------------------------------
* Fix build breaks for very old versions of Ilmbase (1.6 and earlier)
that lack a definition of V4f used by our simd.h.
* Fix signed/unsigned warning on 32 bit platforms in jpeginput.cpp.
Release 1.5 (26 Jan 2015) -- compared to 1.4.x
----------------------------------------------
Major new features and improvements:
* New oiiotool functionality/commands:
* --rotate90, --rotate180, --rotate270 rotate the image in 90 degree
axially-aligned increments with no filtering. (1.5.2)
* --reorient will perform whatever series of rotations or flips are
necessary to move the pixels to match the "Orientation" metadata that
describes the desired display orientation. (1.5.2)
* --autoorient will automatically do the equivalent of --reorient on
every image as it is read in, if it has a nonstandard orientation.
(This is generally a good idea to use if you are using oiiotool to
combine images that may have different orientations.) (1.5.2)
* --rotate rotates an image by arbitrary angle and center point,
with high-quality filtering. (1.5.3)
* --warp transforms an image using a 3x3 matrix, with high-quality
filtering. (1.5.3)
* --median performs a median filter. (1.5.4)
* New ImageBufAlgo functions:
* rotate90(), rotate180(), rotate270() rotate the image in 90 degree
axially-aligned increments with no filtering. (1.5.2)
* reorient() will perform whatever series of rotations or flips are
necessary to move the pixels to match the "Orientation" metadata that
describes the desired display orientation. (1.5.2)
* rotate() performs rotation with arbitrary angle and center point,
with high-quality filtering. (1.5.3)
* warp() transforms an image by a 3x3 matrix, with high-quality
filtering. (1.5.3)
* median_filter performs a median filter. (1.5.4)
* Significant internal speedups by utilizing SIMD instructions (SSE) in
the TextureSystem (1.5.5 , 1.5.6 ). To use this to its
fullest extent, build OIIO with the make/cmake option USE_SIMD=arch,
where arch is sse2, ssse3, sse4.1, sse4.2, depending on what machines
you'll be deploying to. (Note that x86_64 automatically implies at
least sse2.) We're finding that this has approximately doubled the
speed of the math part of texture mapping (it doesn't speed up the disk
I/O, of course). (1.5.5)
* Basic support for many movie files via a plugin using 'ffmpeg'. Works
with avi, mov, qt, mp4, m4a, 3gp, 3g2, mj2, m4v, mpg, and more. Movie
files simply look like multi-image files to OIIO. There isn't really
support for audio yet, and although this lets you retrieve and process
individual frames of a movie file, OIIO is still not meant to be a
video-processing library. Currently, these formats can be read, but
there is no write support (maybe coming soon). (1.5.5)
* Nuke plugins -- a txReader plugins that will read OIIO texture files,
and a txWriter that will output proper (tiled & mip-mapped) texture files
from Nuke. Contributed by Nathan Rusch / Luma Pictures. (1.5.6)
