GD module is an interface to the GD library written by Thomas Bouttel.
"It allows your code to quickly draw images complete with lines,
arcs, text, multiple colors, cut and paste from other images, and
flood fills, and write out the result as a .PNG file. This is
particularly useful in World Wide Web applications, where .PNG is
the unencumbered format used for inline images."
It has been extended in some ways from the original GD library.
1.6.6 (27 Nov 2008)
--------------------
* Fixed issue that caused all images to be 570x570 on some systems, due to a
change in the python2.5 C API.
* Improved setup.py and Makefiles.
* Contours can now be used with PlotKey.
* Added Labels component. Similar to Points, but with text labels instead
of symbols.
1.6.5 (20 Mar 2007)
-------------------
* Replaced Numeric with numpy.
1.6.4 (08 Mar 2004)
-------------------
* Phil Kromer contributed the new ColoredPoints and Density components.
See example9.py for details.
* Todd Fox contributed Makefiles for building with MS Visual C++.
* Can now specify the width/height of postscript output, by passing (e.g.)
width="5in" or height="10in" to the functions which produce postscript
output. Default values are in the [postscript] section of config.ini.
The old [printer]/paper option is now [postscript]/paper.
* Added UpperLimits, LowerLimits components. These produce symbols
with half-arrows indicating the true value is below/above the
point.
* Added TeX codes \`,\',\^,\",\~ for character accents.
The configure script determines the availability of libXxf86dga only by the existence of X11/extensions/xf86dga.h. This leads to a linkage error on platforms (e.g. Darwin) where the header in question can be found in the system default path but the corresponding library is installed elsewhere. The problem goes away if we had the library buildlinked, and I see no reason for not enabling DGA input anyway.
The main motivation is that index.theme now mentions "scalable"
directories, so symbolic icons have a chance of being found.
The licence has changed from GPL2 to CCBYSA3 and LGPL3.
Many icons were added, and a few have been removed:
- logviewer.png which is distributed by gnome-utils
- battery-charging.png which now has a variety of charging states
and some which can be replaced by more generic icons:
- palm-pilot-sync.png -> emblem-synchronizing.png
- palm-pilot.png -> pda.png
- visor.png -> pda.png
upstream or submitted for upstream. Import changes:
A new hidden wire display option was added to help with retopology. Mesh
Bisect is a new tool to cut meshes in half. The Bridge, Edgenet fill,
Grid fill and Symmetrize tools were improved. New curve and lattice
editing tools were added too.
Hair rendering was improved with a new Hair shader and reorganized
settings. Subsurface scattering uses a new sampling algorithm and now
supports bump mapping and texture blurring. Sky rendering now uses a
more accurate sky model. New blackbody, vector transform and HSV nodes
were added. The non-progressive integrator was renamed to Branched Path
Integrator, and is now available for GPU rendering.
The Motion tracker now supports plane tracking, which can be used to
replace billboards, screens and other flat things in footage.
Lists in the user interface can now be resized, sorted and filtered.
Further there are small improvements for vertex parenting, empty
objects, the shrinkwrap modifier, mask editing, armatures, f-curves and
drivers.
FBX Import support has been added and FBX/OBJ can now export split
normals (without the need for the edge split modifier).
In addition to the new features, over 270 bugs that existed in previous
releases have been fixed.

Cosimo Cecchi, Evan Nemerson, Guillaume Desmottes, Ryan Lortie
Clutter-GTK 1.1.2 23/11/2011
===============================================================================
Changes since 1.0:
• Drop all flavours
Since Clutter 1.9 and GTK+ 3.0 support multiple backends with
selection at run-time, Clutter-GTK can drop the multiple flavours,
and support the current Clutter and GDK backend. This is still a
work in progress, so not every Clutter or GDK backend provide the
same set of features. Basic Clutter embedding works with the X11,
GDK, and Windows backends. GTK+ widgets embedding inside Clutter
works only on the X11 backend.
• Do not disable multi-device
Clutter was fixed to support XI2 events coming from GDK without
destroying the event cookie; this means that Clutter-GTK can
stop disabling multi-device support in GDK. If your code was
calling gdk_disable_multi_device() (something that shouldn't have
been done in the first place) this means that event handling
will be broken.
• Make GtkClutterEmbed expand by default
The GtkClutterEmbed widget should expand by default on both#
orientations; this allows using the default size negotiation
mechanisms in GTK, and drop the hack of setting a minimum size
on the widget.
Many thanks to:
Marc-André Lureau, Matthias Clasen

Clutter 1.15.94 2013-09-19
===============================================================================
• List of changes since Clutter 1.15.92
- Improve the evdev input backend
The evdev input backend is used when writing applications and compositors
that directly drive the frame buffer on Linux. By ensuring that the evdev
input backend works correctly it is possible to manage input sources like
pointers, keyboards, and touch devices using the raw evdev device nodes.
Clutter now depends on libevdev in order to poll the evdev interfaces.
- Allow scaling windowing surfaces
The main part of the work to support high resolution displays is to make
sure that windowing surfaces can be created with a scaling factor, while
trasparently handling the new size from an application's perspective. The
scaling factor is currently set manually, but it in the near future it will
be automatically set by the environment.

Cogl 1.15.10 2013-09-02
• List of changes since Cogl 1.15.8
» Added API to set the onscreen template on a CoglDisplay outside of
the constructor.
» Added public API to configure the layout of displays when using
the KMS winsys.
» Added a cogl_point_coord builtin variable for snippets which can
be used to render point sprites in more dynamic ways.
» cogl_texture_new_with_size now returns NULL on failure. This
behaviour was accidentally changed in 1.14.0.
» Fixed a problem with setting the precision specifiers on GLES2
which was causing a lot of problems with the latest Mesa.
» Added a “webgl” driver to manage the differences in GLES2 when
compiling with emscripten.
» Fixed a bug with paths which was causing Clutter's texture-fbo
test to crash.
» Some issues with introspecting the cogl-pango API were fixed.
» Added an example using point sprites.
» Build fixes for building with MinGW32.
» Updates to the MSVC build files.
» Documentation fixes to the snippets API.

Cogl 1.15.8 2013-08-20
• List of changes since Cogl 1.15.6
Brown bag release to fix a problem with including cogl-path.h from
cogl.h that meant only code defining
COGL_ENABLE_EXPERIMENTAL_2_0_API would get access to the CoglPath
API.
We now ignore whether COGL_ENABLE_EXPERIMENTAL_2_0_API is defined so
clutter which does define it will see the api and so will clutter
users that don't define it.
Cogl 1.15.6 2013-08-19
• List of changes since Cogl 1.15.4
» Fixed runtime selection of egl-kms backend
» Split out the CoglPath api in-line with cogl master to reduce
divergence, but updated to not break the 1.x API/ABI
» Reverted the semantic change to cogl_offscreen_new_to_texture to
make it synchronously allocate as it did in cogl-1.14. A
replacement cogl_offscreen_new_with_texture api has been
introduced to support the asynchronous allocation behaviour
required to allow configuration of a framebuffer before
allocation.
» Fixed a problem with binding attribute locations with desktop GL
drivers, required to work with the latest Mesa.
» Some configure.ac documentation fixes
» In cogl-gst we make sure to only emit the "pipeline-ready" signal
once the new textures have actually been uploaded.
» Various MSVC build fixes
Note: we took some care to try and avoid breaking the ABI and
chaning the soname relative to the last 1.15.4 snapshot.

Cogl 1.15.4 2013-07-30
• List of changes since Cogl 1.15.2
» Added experimental API to directly expose atlas textures.
» Added new_from_file/data/bitmap APIs for sliced textures.
» Added new_from_file APIs for 2D textures.
» Added cogl_primitive_draw as a new name for the
cogl_framebuffer_draw_primitive function.
» Removed the attribute drawing APIs. Instead applications should
create a primitive and draw that.
» Fixed bug where Cogl would busy-wait with 100% CPU if the Wayland
compositor is closed.
» The COGL_FRAME_EVENT_SYNC events are now sent based on the frame
callback with the Wayland backend.
» New cogl_gst_video_sink_is_ready() function to determine whether a
Cogl-GST video sink is ready to have the pipeline queried.
» Fixed a potential bug with the blending enabled state when copying
a pipeline.
» Fixed detecting the Mesa vendor when GL 3 is used.
» Fixed a reference leak on the CoglRenderer.
» Fixes to the Visual Studio build files.

Cogl 1.15.2 2013-07-09
• List of changes since Cogl 1.14.0
» Lots of Wayland backend work, including updated compositor support
» Updated cogland, a simple example wayland compositor using Cogl
» Made the onscreen resize callback work the same as the frame callback
» New cogl_onscreen_swap_buffers_with_damage api
» New fence API
» New Emscripten support (only basic at the moment)
» Improved blend state tracking
» New cogl_onscreen_add_dirty_callback() api for window systems
that need to notify application of dirty/damaged regions that must
be redrawn by the application
» Started adding internal unit tests to complement the conformance
tests
» New support for per-vertex point sizes
» New cogl-gst sub-library added enabling gstreamer integration into
Cogl based applications. Notably the design is compatible with
applications adding custom shader snippets to a CoglPipeline that
handles video sampling so application will be able to chain
together shader based affects without requiring intermediate
renderers.
» Adds HSL color conversion apis
» The Conformance test suite can now be installed with a .test file
enabling them to be run by the gnome-desktop-testing-runner for example.

It is for clock_gettime with CLOCK_REALTIME and also changed to use
CLOCK_REALTIME for other than OS X.
Back to use CLOCK_MONOTONIC and use patch for OS X from MacPorts instead.
Bump PKGREVISION.
Security Fixes:
EPT: Fix crash observed when Ghostscript fails to produce useful output. This was particularly noticeable when Ghostscript was not installed. This crash could be used to cause denial of service.
PNG: With libpng 1.6.X, avoid a crash while copying a PNG with a "known incorrect ICC profile". This crash could be used to cause denial of service.
Bug fixes:
Build: Fix cross-compilation for MinGW64 on Linux build machine.
Build: configure FreeType test no longer insists that <freetype/freetype.h> can be included.
CMS profile: Only delete the CMS transform if it is non-null. Fixes assersion observed when lcms returned a null profile and GraphicsMagick attempted to deallocate it.
Drawing: Improve error handling logic so that drawing returns quickly on pixel access errors rather than plowing on ahead. This avoids problems with SVGs which take seemingly forever to render.
Drawing via C/C++ APIs: BevelJoin no longer causes a MVG parsing error.
EPT: Fix crash observed when Ghostscript fails to produce useful output. This was particularly noticeable when Ghostscript was not installed.
OpenMP: Revert use of omp_set_dynamic() since it caused performance issues when using GCC's GOMP implementation and the number of threads to use is specified.
EXIF profile: Support the SubjectArea EXIF tag.
MIFF writer: PseudoClass format was written incorrectly for depth greater than 8.
MIFF writer: RLE compressed format used inverted alpha from the other subformats and contrary to the MIFF specification.
MIFF reader: Fixes Fixes to be able to read MIFF written by ImageMagick 6.X, including DirectClass grayscale images (except for RLE compressed).
Mosaic: Fixed unsigned underflow problem with -mosaic when page offset is negative and exceeds image width or height, resulting in assertions, out of memory errors, or pixel cache limit errors.
PDF: Consistently initialize Image page width and height to image width and height. While general to all of GraphicsMagick, this change is to assure that the PDF writer computes page dimensioning consistently. PDF page dimensioning was wrong if the image had been resized with -geometry "100%".
PAM: Fix MAXVAL scaling when reading PAM images. PAM was only working correctly for images with 256 or 64k levels.
PNM: PGM "P2" format writer wrote bad output for 8-bit depth.
PNG: With libpng 1.6.X, avoid a crash while copying a PNG with a "known incorrect ICC profile".
PNG: Q8 GM build now correctly reads 16-bit PNG files.
TIFF writer: Try to avoid writing more than 32k strips per image by increasing rows-per-strip since some programs fail to read images with more than 32k strips per image.
TIM reader: PSX TIM reports 8-bit depth (rather than 16).
TTF font rendering: Improve FreeType rendering error logic so that rendering returns immediately on pixel access errors rather than plowing on ahead.
TTF font rendering: Support rendering UTF-8 up to 21-bit code points. Was only supporting 16-bit code points.
Wand API: DrawSetStrokeDashArray() / DrawGetStrokeDashArray(), fix failure to work properly due to this code path never being tested.
Windows Ghostscript: 64-bit GraphicsMagick no longer requires both 32-bit and 64-bit builds of Ghostscript to be installed in order to read Postscript and PDF formats.
XPM reader: Reported depth now depends on the colormap rather than always claiming to be 16-bit.
New Features:
JPEG: Add support for writing 'XMP' profile.
PNM: As a simple non-standard extension to the standard PNM and PAM formats, support writing and reading 32-bit sample depth. Writing such files is only supported by the Q32 build although they may be read by any build.
WebP: Now supports reading and writing Google's WebP format. This feature is not currently supported by the Windows Visual Studio build.
Version 1.6.8beta01 [November 24, 2013]
Moved prototype for png_handle_unknown() in pngpriv.h outside of
the #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED/#endif block.
Added "-Wall" to CFLAGS in contrib/pngminim/*/makefile
Conditionally compile some unused functions reported by -Wall in
pngminim.
Fixed 'minimal' builds. Various obviously useful minimal configurations
don't build because of missing contrib/libtests test programs and
overly complex dependencies in scripts/pnglibconf.dfa. This change
adds contrib/conftest/*.dfa files that can be used in automatic build
scripts to ensure that these configurations continue to build.
Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder.
Fixed pngvalid 'fail' function declaration on the Intel C Compiler.
This reverts to the previous 'static' implementation and works round
the 'unused static function' warning by using PNG_UNUSED().
Version 1.6.8beta02 [November 30, 2013]
Removed or marked PNG_UNUSED some harmless "dead assignments" reported
by clang scan-build.
Changed tabs to 3 spaces in png_debug macros and changed '"%s"m'
to '"%s" m' to improve portability among compilers.
Changed png_free_default() to free() in pngtest.c
Version 1.6.8rc01 [December 12, 2013]
Tidied up pngfix inits and fixed pngtest no-write builds.
Version 1.6.8rc02 [December 14, 2013]
Handle zero-length PLTE chunk or NULL palette with png_error()
instead of png_chunk_report(), which by default issues a warning
rather than an error, leading to later reading from a NULL pointer
(png_ptr->palette) in png_do_expand_palette(). This is CVE-2013-6954
and VU#650142.

/usr/X11R7 on its own, and then the PLIST doesn't match, so pass in
${BUILDLINK_PREFIX.freetype2} explicitly.
Also, because if you have tk installed it finds it and then fails
because it isn't buildlinked, pull in tk and add the tk library to the
PLIST.

Produce Encapsulated PostScript Files (EPS/EPSF) from a one-
page PostScript document, or any PostScript document. A correct
Bounding Box is calculated for the EPS files and some
PostScript command sequences that can produce errorneous
results on printers are filtered. The input is cropped to
include just the image contained in the PostScript file. The
EPS files can then be included into TeX documents. Other
programs like ps2epsi (a script distributed with ghostscript)
don't always calculate the correct bounding box (because the
values are put on the PostScript stack which may get corrupted
by bad PostScript code) or they round it off, resulting in
clipping the image. Therefore ps2eps uses a resolution of 144
dpi to get the correct bounding box.

- Translation updates
2.14 Fri Nov 9 16:06:00 2012
- No code changes.
- Patch t/foo.t to not assume text appears on specific lines of the output test files.
2.13 Fri Nov 9 08:27:00 2012
- No code changes.
- Re-package distro because users get errors during testing. See RT#80709.
Since I had this same error during my testing, I assume the uploaded version contains un-patched
code. The errors are not in GraphViz, they are in the test code which has hard-coded line numbers
where it looks for strings in the output. The output has been reformatted recently, and no longer
matches those assumptions. See t/foo.t for details. Note: I did not write those tests :-).
2.12 Thu Nov 8 12:38:00 2012
- No code changes.
- For pre-reqs such as strict, warnings, etc, which ship with Perl, set the version # to 0.
Reported as RT#80663 by Father Chrysostomos for Tree::DAG_Node.
2.11 Tue Sep 18 08:22:00 2012
- Add VDX as an output format.
2.10 Mon Mar 26 10:11:00 2012
- Accept a patch kindly supplied by Alexander Kriegisch, to change handling of the rankdir attribute.
The valid values are BT, LR, RL or TB, or their lower-case equivalents.
Previously, only a true value was accepted, which meant LR. Now, any value not in that list defaults to LR.
Files changed: README, CHANGES, Changelog.ini, GraphViz.pm, GraphViz/Regex.pm and simple.t.
- Patch this file to replace BST with GMT, since both DateTime::Format::HTTP and DateTime::Format::Strptime
fail to recognize BST.
These modules are used by Module::Metadata::Changes to transform this file into Changelog.ini.
2.09 Thu Dec 15 11:08:00 2011
- Adopt Flavio Poletti's suggestion of trying to pipe to dot, in Build.PL/Makefile.PL, rather than using File::Which,
to see if dot (Graphviz) is installed. This (hopefully) solves the problem of using File::Which on systems where it is
not installed, before Build.PL/Makefile.PL has a chance to tell the user that File::Which is required. See: RT#73077.
2.08 Tue Nov 1 10:55:00 2011
- Wind back pre-reqs for various modules to match what was shipped with Perl V 5.8.1.
Many thanx to Brian Cassidy for the error report: https://rt.cpan.org/Ticket/Display.html?id=72068.
2.07 Sun Oct 30 16:08:00 2011
- Rewrite Build.PL and Makefile.PL to try loading File::Which rather than assuming it is installed.
This avoids the chicken-and-egg problem whereby these 2 programs need File::Which::which to find 'dot'.
Many thanx to Richard Clamp for the error report: https://rt.cpan.org/Public/Bug/Display.html?id=71971.
2.06 Tue Oct 25 08:09:00 2011
- Add File::Which to the pre-reqs in Build.PL and Makefile.PL.
2.05 Thu Oct 20 10:52:00 2011
- Add 'Deprecated. See GraphViz2' to the docs.
- Add Build.PL.
- Add ability to set ORIENTATION. Thanx to Christian Lackas for the patch. See RT#71787.
- Add Changelog.ini.
- Add META.json, MYMETA.json and MYMETA.yml.
- Add MANIFEST.SKIP.
- Ensure all modules contain a version number.
- Update the docs regarding the list of modules shipped in this distro.
- Remove examples/remote.pl because GraphViz::Remote is no longer shipped.
- Clean up examples/clusters2.pl.
- Clean up Makefile.PL.
* fixed estimated number of images
* only hide cursor when fullscreen
* default to best available video depth.
* handle missing or bad files better
* experimental "scaling" keys added

* Replaced most "atoi(argv[++i])" with "pngcrush_get_long" which does
"BUMP_I; strtol(argv[i],ptr,10)" and added pngcrush_check_long macro
to detect malformed or missing parameters (debian bug 716149).
* Added global_things_have_changed=1 when reading -bkgd.
* The "-bit_depth N" option did not work reliably and has been removed.
Version 1.6.7beta01 [September 30, 2013]
Revised unknown chunk code to correct several bugs in the NO_SAVE_/NO_WRITE
combination
Allow HANDLE_AS_UNKNOWN to work when other options are configured off. Also
fixed the pngminim makefiles to work when $(MAKEFLAGS) contains stuff
which terminates the make options (as by default in recent versions of
Gentoo).
Avoid up-cast warnings in pngvalid.c. On ARM the alignment requirements of
png_modifier are greater than that of png_store and as a consequence
compilation of pngvalid.c results in a warning about increased alignment
requirements because of the bare cast to (png_modifier*). The code is safe,
because the pointer is known to point to a stack allocated png_modifier,
but this change avoids the warning.
Fixed default behavior of ARM_NEON_API. If the ARM NEON API option was
compiled without the CHECK option it defaulted to on, not off.
Check user callback behavior in pngunknown.c. Previous versions compiled
if SAVE_UNKNOWN was not available but did nothing since the callback
was never implemented.
Merged pngunknown.c with 1.7 version and back ported 1.7 improvements/fixes
Version 1.6.7beta02 [October 12, 2013]
Made changes for compatibility with automake 1.14:
1) Added the 'compile' program to the list of programs that must be cleaned
in autogen.sh
2) Added 'subdir-objects' which causes .c files in sub-directories to be
compiled such that the corresponding .o files are also in the
sub-directory. This is because automake 1.14 warns that the
current behavior of compiling to the top level directory may be removed
in the future.
3) Updated dependencies on pnglibconf.h to match the new .o locations and
added all the files in contrib/libtests and contrib/tools that depend
on pnglibconf.h
4) Added 'BUILD_SOURCES = pnglibconf.h'; this is the automake recommended
way of handling the dependencies of sources that are machine generated;
unfortunately it only works if the user does 'make all' or 'make check',
so the dependencies (3) are still required.
Cleaned up (char*) casts of zlib messages. The latest version of the Intel C
compiler complains about casting a string literal as (char*), so copied the
treatment of z_const from the library code into pngfix.c
Simplified error message code in pngunknown. The simplification has the
useful side effect of avoiding a bogus warning generated by the latest
version of the Intel C compiler (it objects to
condition ? string-literal : string-literal).
Make autogen.sh work with automake 1.13 as well as 1.14. Do this by always
removing the 1.14 'compile' script but never checking for it.
Version 1.6.7beta03 [October 19, 2013]
Added ARMv8 support (James Yu <james.yu at linaro.org>). Added file
arm/filter_neon_intrinsics.c; enable with -mfpu=neon.
Revised pngvalid to generate size images with as many filters as it can
manage, limited by the number of rows.
Cleaned up ARM NEON compilation handling. The tests are now in pngpriv.h
and detect the broken GCC compilers.
Version 1.6.7beta04 [October 26, 2013]
Allow clang derived from older GCC versions to use ARM intrinsics. This
causes all clang builds that use -mfpu=neon to use the intrinsics code,
not the assembler code. This has only been tested on iOS 7. It may be
necessary to exclude some earlier clang versions but this seems unlikely.
Changed NEON implementation selection mechanism. This allows assembler
or intrinsics to be turned on at compile time during the build by defining
PNG_ARM_NEON_IMPLEMENTATION to the correct value (2 or 1). This macro
is undefined by default and the build type is selected in pngpriv.h.
Version 1.6.7rc01 [November 2, 2013]
No changes.
Version 1.6.7rc02 [November 7, 2013]
Fixed #include in filter_neon_intrinsics.c and ctype macros. The ctype char
checking macros take an unsigned char argument, not a signed char.
Version 1.6.7 [November 14, 2013]
Technically this change should bump PKGREVISION (as it changes the
binary package ever so slightly for platforms where the ceill() didn't
cause a build failure) but I'm going to let it slide.

At configure time, guile --version is parsed to see if guile is new
enough, and our guile 1.8 is new enough. But the sed expression,
documented to use BREs, wrongly uses \+ which is a modern RE
construct. gsed interprets \+, and is hereby awarded a "test =="
badge of shame. To fix this, change \+ to *.

Release 1.2 (8 July 2013)
-------------------------
Major new features and improvements:
* New oiiotool commands:
--swap Exchanges the top two items on the image stack.
--fit Resize image to fit into a given resolution (keeping aspect).
--ch Select/cull/reorder/add channels within an image.
--chappend Merge two images by appending their color channels.
--chnames Rename some or all of the color channels in an image.
--zover Depth compositing
--cadd Add constant per-channel values to all pixels
--cmul Multiply an imge by a scalar or per-channel constant.
--fillholes Smoothly interpolate for hole filling.
--resample Similar to --resize, but just uses closest pixel lookup.
--clamp Clamp pixel values
--rangeexpand Expand range for certain HDR processing
--rangecompress Compress range for certain HDR processing
--unpremult Divide colors by alpha (un-premultiply).
--premult Multiply colors by alpha.
--kernel Make a convolution kernel using a filter name.
--convolve Convolve two images.
--blur Blur an image.
--unsharp Sharpen an image using an unsharp mask.
--paste Paste one image on another.
--mosaic Create a rectilinear image mosaic.
--transpose Transpose an image (flip along the diagonal axis)
--chsum Sum all channels in each pixel
--cshift Circular shift an image pixels
--fft --ifft Forward and inverse Fourier transform
--colorcount Counts how many pixels are one of a list of colors.
--rangecheck Counts how many pixels fall outside the given range.
--ociolook Apply OpenColorIO "looks"
--autotrim Shrinks pixel data window upon output to trim black edges.
* oiiotool can loop over entire numeric frame ranges by specifying
wildcard filenames such as "foo.#.tif" or "bar.1-10#.exr".
* oiiotool --frames and --framepadding give more explicit control over
frame range wildcards.
* Significant performance improvements when reading and writing images
using the ImageBuf::read and ImageCache::get_pixels interfaces, and in
some cases also when using regular ImageInput. This also translates
to improved performance and memory use for oiiotool and maketx.
* At least doubled the performance of maketx for large images when run
on multi-core machines.
* Significant performance improvements when using ImageBuf::Iterator
or ConstIterator to traverse the pixels in an ImageBuf, and the iterators
now support "wrap" modes (black, clamp, periodic, mirror).
* maketx --hicomp does "highlight compensation" by compressing the
HDR value range prior to inter-MIP resizes, then re-expanding the range.
* Field3D writer (it could read f3d files before, but not write them).
* idiff can now compare that are not the same size (treating pixels
beyond the pixel data window is being 0 valued).
* maketx --lightprobe turns a "lightprobe" iamge into a latlong environment
map.
* Significant improvements and fixes to EXIF, IPTC, and XMP metadata
reading and writing.
* Significant thread scalability improvements to TextureSystem and
ImageCache.
* Huge overhaul of functionality, style, and performance of the
entire ImageBufAlgo set of functions (see the "Public API changes"
section below, and the imagebufalgo.h file for details).
Public API changes:
* ImageOutput semantics change: If the spec passed to open() has
spec.format set fo UNKNOWN, then select a default data format for the
output file that is "most likely to be able to be read" and/or "most
typical for files of that format in the wild." Also,
ImageOutput::open() will never fail because a requested data format is
unavailable; if the requested format is not supported, a reasonable
alternate will always be chosen.
* ImageBuf has been changed to a "PIMPL" idiom, wherein all the
internals are no longer exposed in the public API. This allows us to
change ImageBuf internals in the future without breaking API or link
compatibility (and thus giving us more freedom to backport important
improvements to prior releases).
* Overhaul of ImageBufAlgo functions: they all take an ROI parameter;
use the DISPATCH macros to make them work with all pixel data types
where practical (previously, many supported float only); use Iterator
rather than getpixel/setpixel, leading to huge speed improvements;
multithread when operating on enough pixels, leading to huge speed
improvements; work on 3D (volume) images where applicable; always
gracefully handle uninitialized dest image or undefined ROI.
* New ImageBufAlgo functions: channels(), channel_append(), mul(),
paste(), zover(), add() and mul() varieties that that add/multiply a
constant amount to all pixels, fillholes_pp(), resample(), clamp(),
rangecompress(), rangeexpand(), make_kernel(), unsharp_mask(),
transpose(), channel_sum(), circular_shift(), fft(), ifft(),
color_count(), color_range_check(), nonzero_region().
[look in imagebufalgo.h for documentation.]
* 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. Two varieties exist: one that takes a
filename and reads from disk, another that takes an ImageBuf already
in memory.
* ImageBuf Iterator/ConstIterator now take "wrap" mode parameters that
allow out-of-range iterators to be able to retrieve valid data. Supported
wrap modes include black, clamp, periodic, and mirror. This simplifies
a lot of algorithms using IB::Iterator, they can now be written to
rely on wrap behavior rather than being cluttered with checks for
"if (it.exits())" clauses.
* ImageBufAlgo::computePixelHashSHA1 has been refactored to take ROI,
a block size, and thread count, and thus can be parallelized with threads.
The block size means that rather than computing a single SHA-1 for all
the pixels, it computes separate (parallel) SHA-1 for each group of
blocksize scanlines, then returns the SHA-1 of all the individual SHA-1
hashed blocks. This is just as strong a hash as before, thought the value
is different than doing the whole thing at once, but by breaking it into
blocks the computation can be multithreaded.
* ImageBuf::swap() makes it easy to swap two ImageBuf's.
* ImageSpec::get_channelformats is now const (and always should have been).
Fixes, minor enhancements, and performance improvements:
* TextureSystem improvements:
* Make sure "black" wrap wins out over "fill" value when they conflict
(looking up an out-of-range channel beyond the pixel data window).
* "mirror" wrap mode was slightly incorrect and has been fixed.
* oiiotool improvements:
* oiiotool -v breaks down timing by individual function.
* oiiotool has been sped up by forcing read of the whole image up front
for reasonably-sized files (instead of relying on ImageCache).
* oiiotool does not write output images if fatal errors have occurred.
* oiiotool --diff: Better error handling, better error printing, and
now it can compare images with differing data windows or channel
numbers ("missing" channels or pixels are presumed to be 0 for the
purposes of comparing).
* oiiotool --resize (and --fit): properly handle the case of resizing
to the same size as the original image.
* oiiotool -d CHAN=TYPE can set the output for just one channel.
* ImageBufAlgo improvements:
* Internal overhaul of IBA::resize to greatly speed it up.
* Improve IBA::resize to handle the image edge better -- instead of
clamping, just don't consider nonexistant pixels.
* More careful selection of filter when resizing (IBA::resize, oiiotool
--resize and --fit, and maketx).
* Fix IBA::paste() error when the foreground image runs off the end of
the background image.
* Bug fix when computing SHA-1 hash of 0-sized images.
* Image format support improvements:
* Bug fix where some format readers (PNM, SGI, and IFF) would leave the
file handle opened if the ImageInput was destroyed without calling
close() first. Now we guarantee that destroying the II always causes
the file to close().
* DPX: output allocation bug fix; properly set pixel aspect ratio for
DPX write.
* IFF: bug fix for endian swap for IFF file input.
* JPEG2000: fix warnings, make sure event manager transfer object
remains valid.
* OpenEXR: when reading, was botching the ordering of per-channel data
formats.
* SGI write: bug fix for the case of 15 bpp RLE encoding, was
double-swapping bytes.
* Targa: more robust check for presence of alpha channels; bug fix where
R and B channels were reversed for certain kinds of palette images.
* TIFF: Store the orientation flag properly when outputting a TIFF file.
* maketx improvements:
* maketx --chnames allows you to rename the channels when you create a
texture.
* maketx bug fixes: incorrect weighting when resizing MIP levels for
latlong environment map images that could make visible artifacts
on some intermediate MIP levels.
* encode_exif() didn't copy the right number of bytes.
* Python bindings: ImageSpec extra_attribs now properly responds to
iterator calls.
* Fix bug in sRGB -> linear conversion.
* iv: make pixelview display coordinates & color even when outside the
data window.
Build/test system improvements:
* Many fixes to improve builds and eliminate warnings on Windows and MinGW.
* Fix missing InterlockedExchangeAdd64 for Windows XP.
* New make/cmake boags: OIIO_BUILD_TOOLS=0 will exclude building of the
command line tools (just build libraries), OIIO_BUILD_TESTS=0 will
exclude building of unit test binaries.
* Improved matching of testsuite reference images on different platforms.
* Lots of fixes to compiler warnings on newer gcc and clang releases.
* Unit tests for Timer class.
* libOpenImageio/imagespeed_test benchmarks various methods of reading
and writing files and iterating image pixels (to help us know what to
optimize).
* If OpenSSL is available at build time, OIIO will use its SHA-1
implementation instead of our own (theirs is faster). We still fall
back on ours if OpenSSL is not available or when OIIO is built with
USE_OPENSSL=0.
* Allow default the shared library suffix to be overridden with the
CMake variable OVERRIDE_SHARED_LIBRARY_SUFFIX.
* Eliminated all uses of the custom DEBUG symbol, and instead use the
more standard idiom "#ifndef NDEBUG".
* Compatibility fixes for Python3.
* MSVC 2008: Prevent a redefinition error when using boost::shared_ptr.
* Fixes for compatibility with libtiff 4.0.
* Fixes for MSVC debug mode having out-of-bound exceptions.
* Fixes for libjpeg 9.x.
* Compile to treat warnings as errors (you can disable this with
STOP_ON_WARNING=0).
* New filter: "sharp-gaussian".
* Fix various Windows build errors.
* Improvements to the build when finding IlmBase/OpenEXR.
* Various fixes to compile on ARM architecture.
* Fixes to compile on ESA/390 mainframe (!).
* testtex --threadtimes, --trials, --iters, --nodup, --wedge. These
are helpful in using testtext to benchmark the texture system.
* Improvements to make more tests work properly on Windows.
Developer goodies:
* Improved ASSERT and DASSERT macros to not generate warning for certain
debug compiles; key their debug behavior by the absence of the standard
NDEBUG idiom rather than presence of a custom DEBUG symbol; rename the
message variants ASSERT_MSG and DASSERT_MSG.
* Change the default for Sysutil::memory_used to report resident memory
rather than virtual process size.
* Multithread/parallel version of utility function convert_image().
* imagebufalgo.h improvements and expansion of the various DISPATCH_*
macros.
* New Filesystem utilities: parent_path(), get_directory_entries().
* New Strutil utilities: extract_from_list_string
* spinlock tweaks make it faster than TBB's spin locks!
* By default, we no longer build or use TBB (it's considered deprecated,
but in 1.2 can still be turned on with USE_TBB=1).
* In fmath.h, added definitions for safe_inversesqrt, safelog, safe_log2,
safe_log10, safe_logb.
* In typedesc.h, added TypeDesc::tostring() function.
* unordered_map_concurrent.h contains a template for a thread-safe
unordered_map that is very efficient even for large number of threads
simultaneously accessing it.
* Documentation: Finally, a chapter in the PDF docs that fully describes
the ImageBuf class.
Release 1.1.13 (24 Jun 2013)
----------------------------
* Texture: make sure wrap mode "black" wins over "fill" value when they
conflict.
Release 1.1.12 (20 Jun 2013)
----------------------------
* Fix oiiotool '#' wildcard, was broken on Windows.
* Fix an overflow problem that plagued 'maketx' when running on input
larger than 32k x 32k (among other possible failures).
Release 1.1.11 (29 May 2013)
----------------------------
* IFF input: bug in endian swap of 16 bit IFF files.
* oiiotool: fix a minor bug where tiled files were output inappropriately.
(Had been patched in master some time ago.)
* fmath.h additions: safe_inversesqrt, safe_log, safe_log2, safe_log10,
safe_logb. These are versions that clamp their inputs so that they
can't throw exceptions or return Inf or NaN.
* Fix to not incorrectly print ImageCache stats for certain broken files.
Release 1.1.10 (13 Apr 2013)
----------------------------
* IBA::fillholes() and oiiotool --fillholes can smoothly fill in alpha
holes with nearby colors. Great for extrapolating the empty areas of
texture atlas images so that filtered texture lookups pull in a plausible
color at part edges.
* IBA::clamp and oiiotool --clamp clamp pixel values to a scalar or
per-channel min and/or max, or clamp alpha to [0,1].
* IBA::rangecompress()/rangeexpand(), and oiiotool --rangecompress /
--rangeexpand compress the excess >1 values of HDR images to a log
scale (leaving the <= 1 part linear), and re-expand to the usual
linear scale. This is very helpful to reduce ringing artifacts that
can happen when an HDR image is resized with a good filter with negative
lobes (such as lanczos3), by doing a range compression, then the resize,
then range expansion. It's not mathematically correct and loses energy,
but it often makes a much more pleasing result.
* maketx --hicomp does highlight compression -- automatically doing a
range compress before each high-quality resize step, and then a
range expansion and clamp-to-zero (squash negative pixels) after
each resize.
* DPX - when writing DPX files, properly set the pixel aspect ratio.
Release 1.1.9 (2 Apr 2013)
--------------------------
* IBA::resize and oiiotool --resize/--fit: Bug fixes to resize filter
size selection fix artifacts wherein extreme zooms could end up with
black stripes in places where the filters fell entirely between samples.
* oiiotool --fit: fix subtle bugs with aspect ratio preservation for
images with differing data and display windows; and allow "filter=..."
to override the default filter used for fit.
* Resize improvement: fix potential artifacts at the image edges resulting
from odd clamping behavior.
* Even more frame range wildcard flexibility with oiiotool --frames and
--framepadding options.
* oiiotool --resize and --fit (and the underlying IBA::resize()) have been
sped up significantly and are now also multithreaded.
Release 1.1.8 (15 Mar 2013)
---------------------------
* oiiotool --chappend (and ImageBufAlgo::channel_append() underneath) allow
you to take two files and concatenate their color channels.
* oiiotool --chnames allows you to rename some or all of a file's color
channels.
* oiiotool can loop over entire frame ranges by specifying wildcard
filenames such as "foo.#.tif" or "bar.1-10#.exr".
* Cmake: OVERRIDE_SHARED_LIBRARY_SUFFIX allows the shared library suffix
to be overridden (e.g., if you need to force .so names on OSX rather
than the usual default of .dylib).
Now depends on lcms2 instead of lcms, and the major version was
bumped (recursive bump following next).
2.0.1 (19.01.2013)
---------------------------
[szukw000@arcor.de] There has been a change in JPEG version 9:
added some code in libmng_types.h before
#include <jpeglib.h>
2.0.0 (dd.mm.2012)
---------------------------
Allows lcms1/lcms2:
./configure --with-lcms2
cmake -DWITH_LCMS2:bool=on
Cnf. the sample files
'Configure.libmng'
and 'build-mng-cmake.sh'
and 'cmake-compile.bat' resp. 'clean.bat'
szukw000@arcor.de
== 1.4.2 / 2013-06-30
Maintenance:
* Modernized Hoe installation of Color, removing some dependencies.
* Switched to Minitest.
* Turned on Travis CI.
* Started using Code Climate.
* Small code formatting cleanup that touched pretty much every file.
libpng-1.6.5 has been released, to remove two stray lines in arm/arm_init.c
that caused libpng to fail to compile when ARM support is enabled. This
problem was apparently due to a cut-and-paste error of some sort on my part.
Changes since the last public release (1.6.3):
Added information about png_set_options() to the manual.
Delay calling png_init_filter_functions() until a row with nonzero filter
is found.
Fixed inconsistent conditional compilation of png_chunk_unknown_handling()
prototype, definition, and usage. Made it depend on
PNG_HANDLE_AS_UNKNOWN_SUPPORTED everywhere.
New features (July 2013)
Graphviz now supports the star node shape and a variation of linear
gradient fill with no gradient (thus, two solid colors) where the
user can specify the proportion using a colorList type for fillcolor.
New Release 2.30 (January-February 2013)
The 2.30 Release marks the switch over from the original Graphviz
graph library to the new cgraph library. If this works as planned,
the user should see no differences. The advantage of the library
is that it is much more flexible for the programmer, with a cleaner
API and support for dynamic data structures. This latter, in addition
to allowing easier mixing of algorithms, has the potential to
greatly reduce memory use in Graphviz.
One side-effect of the new library is a new level ranking algorithm
for dot. This algorithm has fewer constraints, so it is now possible
for a node to be in a cluster and be involved in a rank=same
constraint.
New features (November 2012)
We have provided Graphviz with some additional graphics, which can
be used to provide more semantic information in a graph or enhance
its aesthetics. These include gradient fill for nodes and graphs;
striped and wedged fills, so the amount of each color can be used
to represent some percentage; new node shapes pertinent to the
synthetic biology community (Thanks to Jenny Cheng); and curved
edge routing.
New features (September 2011)
We added lightweight edge labels (xlabel) and tapered edges (as a
style). There was a recent paper by Holten et al about a study of
the readability of various edge styles. We're working on some
examples and documentation. Here are some examples. (We need a
better example for xlabels, because they can float, and aren't
stuck to the upper left of the node.)
New Release 2.28 (Summer 2011)
The 2.28 release of Graphviz incorporates GvMap (formerly GMap, or
"graphs as maps"), an invention by Emden Gansner, Yifan Hu, and
Stephen Kobourov. Try the cool interactive demos showing maps of
music, TV, books, and more.
For people (like us) that care about such matters, we worked pretty
hard to tweak the font rendering code, to eliminate glitches causing
off-center labels or the ransom-note effect.
John Ellson finished porting Graphviz to Solaris OpenCSW.
We changed our license to the EPL (Eclipse Public License). (A
wikipedia article attempts to explain the differences, which we
believe to be fairly limited but the change may help some commercial
licensees.)
