Changelog:
Release 1.1.7 (21 Feb 2013)
---------------------------
* Back out dangerous change to thread.h that was in 1.1.6, which could
cause performance problems.
* Compile fix for WIN32 in strutil.cpp
* Compile fix for Windows XP - add implementation of InterlockedExchangeAdd64
Release 1.1.6 (11 Feb 2013)
---------------------------
* Fix bug that could generate NaNs or other bad values near the poles of
very blurry environment lookups specifically from OpenEXR latlong env maps.
* Fix bug in oiiotool --crop where it could mis-parse the geometric parameter.
* Fix bug in ImageCache::invalidate() where it did not properly delete the
fingerprint of an invalidated file.
* Cleanup and fixes in the oiiotool command line help messages.
* New function ImageBufAlgo::paste() copies a region from one IB to another.
* oiiotool --fit resizes an image to fit into a given resolution (keeping the
original aspect ratio and padding with black if needed).
* ImageBufAlgo::channels() and "oiiotool --ch" have been extended to allow
new channels (specified to be filled with numeric constants) to also be
named.
* New function ImageBufAlgo::mul() and "oiiotool --cmul" let you multiply
an image by a scalar constant (or per-channel constant).
* Important maketx bug fix: when creating latlong environment maps as
OpenEXR files, it was adding energy near the poles, making low-res
MIP levels too bright near the poles.
* Fix to "oiiotool --text" and "oiiotool --fill" -- both were
incorrectly making the base image black rather than drawing overtop of
the previous image.
* Fix FreeBSD compile when not using TBB.
* New oiiotool --swap exchanges the top two items on the image stack.
* Fix distname
Changelog:
Release 1.1.5 (29 Jan 2013)
---------------------------
* Bug fix in ImageBufAlgo::parallel_image utility template -- care when
not enough work chunks to dole out to all the threads (was previously
sending work to threads with nonsensical ROI's, now we just stop when
all the regions have been doled out).
* Additional optional argument to IBA::zover that, when nonzero, will
treat z=0 pixels as infinitely far away, not super close. You can turn
this on from oiiotool with: oiiotool --zover:zeroisinf=1 ...
Release 1.1.4 (27 Jan 2013)
---------------------------
* ImageBufAlgo::make_texture() allows you to do the same thing that
maketx does, but from inside an application and without launching a
shell invocation of maketx.
* oiiotool now recognizes --metamatch and --nometamatch arguments which
cause metadata names matching (or only info NOT matching) the given
regular expression to be printed with --info.
* oiiotool --zover does z (depth) composites (it's like a regular "over",
but uses the z depth at each pixel to determine which of the two images
is the foreground and which is the background).
* ImageBufAlgo::zover() performs z compositing (same as oiiotool --zover).
* ImageBufAlgo::fixNonFinite didn't work properly with 'half' image buffers.
* Performance improvements when reading and writing images.
* Fix error when writing tiled 'float' TIFF images, corrupted output.
(Could easily happen when using 'maketx' to convert float images into
TIFF textures.)
* Eliminate warnings when compiling with Clang 3.2.
* New CMake variable "USE_EXTERNAL_TBB" can optionally be set to force use
of an external TBB library rather than the embedded one.
* Additional testsuite tests (doesn't affect users, but makes bugs easier
to catch).
* Fix build problem with SHA1.cpp on some platforms.
Release 1.1.3 (9 Jan 2013)
---------------------------
* Build fix: incorrectly named OpenEXR 2.x files.
* Bug fix in oiiotool --croptofull on OSX
* Build fixes for MinGW on Windows.
* maketx --fullpixels option ignores any origin or display window in the
source image, pretending the pixel data is the entire 0-1 image range
starting at the origin (useful when the source image is created by an
application that incorrectly writes it out as if it were a crop window).
* maketx no longer will clobber existing ImageDescription metadata
when it adds SHA-1 hash or other info as it creates the texture.
* Many additional Exif and IPTC tags are correctly recognized.
* maketx and oiiotool recognize and take advantage of IPTC:ImageHistory
metadata.
--------------------------
* maketx fixes -- was botching creation of textures from source images that
were crop windows (pixel window smaller than display window).
* Minor bug fix to Timer when repeatedly starting and restopping (Apple only).
* Bug fix in ustring:find_last_not_of
OpenImageIO is a library for reading and writing images, and a
bunch of related classes, utilities, and applications. There is
a particular emphasis on formats and functionality used in
professional, large-scale animation and visual effects work for
film. OpenImageIO is used extensively in animation and VFX studios
all over the world, and is also incorporated into several commercial
products.
