This release adds a "simplified API" and removes some features
that have been deprecated since libpng.1.5.x.
Changes to Libpng from version 1.5.x to 1.6.x:
A "simplified API" has been added (see documentation in png.h and a simple
example in contrib/examples/pngtopng.c). The new publicly visible API
includes the following:
macros:
PNG_FORMAT_*
PNG_IMAGE_*
structures:
png_control
png_image
read functions
png_image_begin_read_from_file()
png_image_begin_read_from_stdio()
png_image_begin_read_from_memory()
png_image_finish_read()
png_image_free()
write functions
png_image_write_to_file()
png_image_write_to_stdio()
Starting with libpng-1.6.0, you can configure libpng to prefix all exported
symbols, using the PNG_PREFIX macro.
We no longer include string.h in png.h. The include statement has been moved
to pngpriv.h, where it is not accessible by applications. Applications that
need access to information in string.h must add an '#include "string.h"'
directive. It does not matter whether this is placed prior to or after
the '"#include png.h"' directive.
The following API are now DEPRECATED:
png_info_init_3()
png_convert_to_rfc1123() which has been replaced
with png_convert_to_rfc1123_buffer()
png_data_freer()
png_malloc_default()
png_free_default()
png_reset_zstream()
The following has been removed:
png_get_io_chunk_name(), which has been replaced
with png_get_io_chunk_type(). The new
function returns a 32-bit integer instead of
a string.
The png_sizeof(), png_strlen(), png_memcpy(), png_memcmp(), and
png_memset() macros are no longer used in the libpng sources and
have been removed. These had already been made invisible to
applications
(i.e., defined in the private pngpriv.h header file) since
libpng-1.5.0.
The signatures of many exported functions were changed, such that
png_structp became png_structrp or png_const_structrp
png_infop became png_inforp or png_const_inforp
where "rp" indicates a "restricted pointer".
Error detection in some chunks has improved; in particular the iCCP chunk
reader now does pretty complete validation of the basic format. Some bad
profiles that were previously accepted are now rejected, in particular the
very old broken Microsoft/HP sRGB profile.
The library now issues a warning if both background processing and RGB to
gray are used when gamma correction happens. As with previous versions of
the library the results are numerically very incorrect in this case.
There are some minor arithmetic changes in some transforms such as
png_set_background(), that might be detected by certain regression tests.
Unknown chunk handling has been improved internally, without any API change.
This adds more correct option control of the unknown handling, corrects
a pre-existing bug where the per-chunk 'keep' setting is ignored, and makes
it possible to skip IDAT chunks in the sequential reader.
* --tray-overlay option added - use this to overlay a EPS file onto the
tray, for example, a barcode image.
* cdinsert.pl now used to display initial form, as well as a
filled-in form to allow for easy corrections/resubmits on the done page.
* Create covers for double-sided DVD cases that hold 6 DVDs.
* cdinsert.pl now supports "Omit title/subtitle from Cover" option.
* Support for double-depth slim DVD cases. --slim-double-case option added.
Release 1.12.14 (2013-02-10 Chris Wilson <chris@chris-wilson.co.uk>)
====================================================================
In the last week we had a few more bugs reported and promptly resolved.
As these are a combination of regressions and stability issues, it is
time for a prompt update and release. Many thanks to everyone for
testing and reporting issues, and helping to make Cairo better.
Bug fixes
---------
Prevent user callbacks accessing user-data during destroy to prevent
use-after-free bugs.
https://bugzilla.mozilla.org/show_bug.cgi?id=722975
Use standard names for glyphs in subset fonts (PDF).
https://bugs.freedesktop.org/show_bug.cgi?id=60248
Fix detection of Win98. The logic for detecting Win98 (and its broken
AlphaBlend()) was inverted, disabling AlphaBlend() for everyone.
Prevent numeric overflow from extrapolating polygon edges to the clip
boundary and causing severe render artifacts.
https://bugs.freedesktop.org/show_bug.cgi?id=60489
Fix computation of glyph string coordinates when breaking up runs
for xlib.
Fix an assertion in the win32 backend for failing to clear its
similar-images.
https://bugs.freedesktop.org/show_bug.cgi?id=60519
RMagick 2.13.2
o Fixed issues preventing RMagick from working with version 6.8 or higher
o Fixed issues preventing RMagick from working with ruby 1.9.3
* 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.
Do not do the heuristic trials of the first 10 methods when -brute is
specified, because it did not save time as I hoped.
Fixed a mistake in 1.7.45 and 1.7.46 that caused the output file to
not be written.
Version 1.7.46 (built with libpng-1.5.13 and zlib-1.2.7)
Moved the new level 0 methods to the end of the trial list (methods 137-148)
Version 1.7.45 (built with libpng-1.5.13 and zlib-1.2.7)
Added method 0 (uncompressed). "-m 0" now simply turns on method 0.
Added "-try10" option that has the same effect that "-m 0" previously did,
namely to try only the first ten methods.
Inserted new methods 17 through 21 with zlib level 0.
Do the heuristic trials of the first 10 methods when -brute is specified,
to get quickly to a small solution, so we can bail out of most of the
remaining trials early. Previously these 10 methods were skipped during
a -brute run.
Removed the "-reduce" line from the help screen when PNGCRUSH_COUNT_COLORS
is disabled.
Jul 9 2012:
Make it compile clean with visual studio 10
Jul 28 2012:
Various cleanups from debian folks.
Oct 19 2012:
Add feature to show quality of jpeg, (by Andy Spiegel)
Dec 27 2012:
Fix crash on some corrupt files bug, clarify time adjustment syntax in help
Release 1.12.12 (2013-01-31 Chris Wilson <chris@chris-wilson.co.uk>)
===================================================================
The goal of this release is to fix the synchronisation problems that
were exhibited in the SHM transport for cairo-xlib. This cropped up
any place that tried to rapidly push fresh pixel data to the X server
through an ordinary image surface, such as gimp-2.9 and evince.
Bug fixes
---------
Avoid replacing the entire image when uploading subimages
https://bugs.freedesktop.org/show_bug.cgi?id=59635
Force synchronisation for scratch SHM image buffers, so that we do
not overwrite data as it is being read by X.
https://bugs.freedesktop.org/show_bug.cgi?id=59635 (also)
Fix typos in detecting multisampling for the GL (MSAA) backend.
Fix a memory leak in the GL (MSAA) backend.
Fix a reference counting bug when mapping a GL surface to an image.

== 2.0.0: 2012-08-29
Major version up!
Slides and themes can be shared. Both of them can be registered as gem
at RubyGems.org. If you specify a slide gem, ((%rabbit%)) command
installs and shows it automatically. If you specify a theme gem,
((%rabbit%)) command installs and uses it automatically.
A tool that publishes your slide to SlideShare with one command is
also added. You can share your slide more easily.
Some utilities such as RabbiRack and Rabbiter are splited as new
packages. You needed to install related libraries manually. Now, you
can install them automatically by installing those tools. It's easy to
install.
=== Improvements
==== rabbit
* Made gettext gem required library.
* Made rttool gem required library.
* Supported relative path image in slide that is specified as URL.
* Supported .rabbit file in the current directory. If the file exists,
command line arguments are read from the file.
* Supported a directory that has .rabbit as source file.
* Supported a slide that is published as gem.
* Supported a theme that is published as gem.
* Added --options-file option that reads command line arguments from
the specified file.
* Removed setup.rb.
* Removed obsoleted --druby-uri option.
* Removed the default image directory customization feature on
install. It's not neeed now.
* Used (({theme.rb})) as the Ruby script file for theme.
(({#{THEME_NAME}.rb})) is still available but it's obsoleted.
* Supported (({.})) as the special theme name. It uses a theme in
the current directory.
==== rabbit-slide
New feature. It provides the following slide related features.
* Scaffolds a new slide.
* Uploads a slide to RubyGems.org.
* Uploads a slide to SlideShare.
* Shows a slide easily.
* Generates a PDF easily.
==== rabbit-theme
New feature. It proves the following theme related features.
* Scaffolds a new theme.
* Uploads a theme to RubyGems.org.
* Shows a theme by benchmark slide.
* Generates a PDF easily.
==== Theme
* background-image-toolkit: Supported a background image specified by URL.
[Suggested by Youhei SASAKI]
* image-slide-number: Showed page number in flags by default.
* default: Enabled hare and tortoise by default.
=== Fixes
==== Documentation
* Fixed wrong description of numerical character reference.
[Reported by znz]
=== Changes

Add cjpeg -rgb1 option to create an RGB JPEG file, and insert
a simple reversible color transform into the processing which
significantly improves the compression.
The recommended command for lossless coding of RGB images is now
cjpeg -rgb1 -block 1 -arithmetic.
As said, this option improves the compression significantly, but
the files are not compatible with JPEG decoders prior to IJG v9
due to the included color transform.
The used color transform and marker signaling is compatible with
other JPEG standards (e.g., JPEG-LS part 2).
Remove the automatic de-ANSI-fication support (Automake 1.12).
Add remark for jpeg_mem_dest() in jdatadst.c.
Support files with invalid component identifiers (created by Adobe PDF).
Adapt full buffer case in jcmainct.c for use with scaled DCT.
Add type identifier for declaration of noreturn functions.
Correct argument type in format string, avoid compiler warnings.
Add missing #include directives in configuration checks, avoid
configuration errors.
Version 1.7.43 (built with libpng-1.5.13 and zlib-1.2.7)
Added "remove(inname)" before "rename(outname, inname)" when using the "-ow"
option on CYGWIN/MinGW because "rename()" does not work if the target file
exists.
Use the bundled "zlib.h" when PNGCRUSH_H is defined, otherwise use the
system .
Version 1.7.42 (built with libpng-1.5.13 and zlib-1.2.7)
Use malloc() and free() instead of png_malloc_default() and
png_free_default(). This will be required to run with libpng-1.7.x.
Revised the PNG_ABORT definition in pngcrush.h to work with libpng-1.7.x.
Revised zutil.h to avoid redefining ptrdiff_t on MinGW/CYGWIN platforms.
Changes since the last public release (1.5.13):
Added -DZ_SOLO to contrib/pngminim/*/makefile to work with zlib-1.2.7
Warn about the incorrect runtime library setting for VS2010 debug DLL builds.
Fixed build when using #define PNG_NO_READ_GAMMA in png_do_compose() in
pngrtran.c (Domani Hannes).
Check for png_ptr==NULL earlier in png_zalloc().
Ignore, with a warning, out-of-range value of num_trans in png_set_tRNS().
Rearranged building of ARM NEON optimizations. The ARM specific code is
split out entirely to the arm subdirectory and changes to configure.acand
Makefile.am to add new stuff are reduced. Now material code changes,
although for build test purposes, --enable-arm-neon now builds on non-ARM
systems.
Rebuilt Makefile.in, configure, etc., with autoconf-2.69 and automake-1.12.5.
Fixed cases of unquoted DESTDIR in Makefile.am
Fixed a minor bug in types to malloc and major bug in handling compressed
iTXt. Compressed iTXt could not be handled.
Cleaned up whitespace in the synopsis portion of the manpage "libpng.3"
Disassembled the version number in scripts/options.awk (necessary for
building on SunOs).
Fixed Windows build issues, enabled ARM compilation. Various warnings issued
by earlier versions of GCC fixed for Cygwin and Min/GW (which both use old
GCCs.) ARM support is enabled by default in zlib.props (unsupported by
Microsoft) and ARM compilation is made possible by deleting the check for
x86. The test programs cannot be run because they are not signed.
Fixed 'make distcheck' on SUN OS - libpng.so was not being removed
Replaced AM_CONFIG_HEADER(config.h) with AC_CONFIG_HEADERS([config.h])
in configure.ac
De-configured build fixes to make a range of deconfiguration options (such
as switching off read or write support) work in more cases. Also upgraded
pngtest and pngvalid to the libpng 1.6 versions (with some modifications)
which provide more extensive testing. Replaced pngtest.png because pngtest
writes the ancillary chunks in a different order.
Check validity of "num_unknowns" parameter of png_set_unknown_chunks()
(Bug report from yuris).
Check the validity of the "nentries" parameter of png_set_sPLT() and the
"num_text" parameter of png_set_text_2().
Packaged for wip by myself, netcap, and othyro.
QComicBook is a viewer for comic book archives containing
jpeg/png/xpm/gif images, which aims at convenience and simplicity.
Features include: automatic decompression, full-screen mode,
two-pages viewing, Japanese mode, thumbnails view, page scaling,
mouse or keyboard navigation etc.
Packaged for wip by othyro.
A general purpose high-pass filter plugin. It shows up as
Filters->Generic->High Pass Filter. You can select a blur radius that sets the
size of detail to be passed by the filter, a contrast adjustment, as well as an
option to keep the source layer or replace it.
It actually implements 5 different high pass modes:
1. Colour - I think this is the same as photoshop's high pass filter effect.
2. Preserve DC - like colour, but adds the average image colour back in.
3. Greyscale - this desaturates the layer before high pass filtering.
4. Greyscale, Apply Chroma - as above, but blends it in with the source
layer colours
5. Redrobes - (named after the technique described by Redrobes)
Release 1.12.10 (2013-01-16 Chris Wilson <chris@chris-wilson.co.uk>)
===================================================================
A heap of bug fixes everywhere, and the gradual completion of the MSAA
backend for cairo-gl. Perhaps the most noteworthy set of the bugfixes
was the crusage lead by Behdad Eshfabod to make font handling by
pango/cairo/fontconfig fully threadsafe. This testing revealed a couple
of races that needed fixing in Cairo's scaled-font and glyph cache.
Bug fixes
---------
Append coincident elements to the recording's surface bbtree so that
the list is not corrupted and the overlapping elements lost.
Fix cairo-trace to correctly record map-to-image/unmap-image and then
replay them.
Ignore MappingNotifies when running the XCB testsuite as they are sent
to all clients when the keyboard changes. The testsuite would detect
the unexpected event and complain.
Handle very large large images in the XCB backend.
Fix a memory leak in the xlib/shm layer, and prevent use of the SHM
surfaces after the display is closed.
https://bugs.freedesktop.org/show_bug.cgi
Handle resizing of bitmap fonts, in preparation for a fix to
fontconfig to correctly pass on the user request for scaling.
Always include subroutine 4 (hint replacement idion) when subsetting
type 1 fonts in order to prevent a crash in cgpdftops on Mac OS/X
Fix a couple of typos in the cairo-gobject.h header files for
introspection.
Prevent a mutex deadlock when freeing a scaled-glyph containing a
recording-surface that itself references another scaled-glyph.
https://bugs.freedesktop.org/show_bug.cgi?id=54950
Make scaled-font cache actually thread-safe and prevent
use-after-frees.
Restore support for older versions of XRender. A couple of typos and a
few forgotten chunks prevented the xlib compositor from running
correctly with XRender < 0.10. Note that there are still a few
regressions remaining.
Changelog:
Fix export resolution rounding issue (as in previous version it could be off-by-one)
Correctly set output dimension in exif instead of passing the raw resolution verbatim
Local average green eq. was fixed (it now works on high ISO images as well, and should no longer produce hot pixels)
Use ordered arrays in XMP files
Disable export parallelism for flickr/picasa export
Don't enter tethering mode when there is no camera attached (this made darktable look as if it was hung, even though that wasn't the case)
Bring back the pin for map thumbnails
Improved TIFF support
Vignetting now has a dithering option (to mitigate occasional banding)
Read Nikon subject distance properly
Assorted FreeBSD fixes
