Imager release history. Older releases can be found in Changes.old
+Imager 0.78 - unreleased
+===========
+
+ - add each library-directory/pkgconfig/ to the pkg-config search path
+ in Imager::Probe.
+ Thanks to Justin Davis.
+ https://rt.cpan.org/Ticket/Display.html?id=60491
+
+ - moved GIF, TIFF file handling code into sub-modules in preparation
+ for separate distribution.
+ https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
+
+Bug fixes:
+
+ - Imager::Probe was calling ExtUtils::Liblist to initialize
+ LD_RUN_PATH supplying an undefined value rather than the found
+ directory. Thanks to Justin Davis.
+ https://rt.cpan.org/Ticket/Display.html?id=60491
+
+ - only prepend ./ to font filenames when passing them to T1Lib and
+ then only when it would use its search mechanisms.
+ https://rt.cpan.org/Ticket/Display.html?id=60509
+
+
+Imager 0.77 - 11 Aug 2010
+===========
+
+I don't want Imager::File::PNG indexed as part of Imager, but forgot
+to update the META.yml before updating the version.
+
+ - don't index Imager::File::PNG as part of Imager
+
+ - add resources to META.yml
+
+Imager 0.76 - not released
+===========
+
+Bug fixes:
+
+ - the align_string() method would ignore a string of "0" due to a
+ mis-use of C< ||= >.
+ Thanks to Maurice Height for reporting this.
+ https://rt.cpan.org/Ticket/Display.html?id=60199
+
+Imager 0.75_03 - 09 Aug 2010
+==============
+
+Bug fixes:
+
+ - read_types() and write_types() would include png when it wasn't
+ available due to a problem with the %formats tie
+
+ - handle dependent libraries correctly (eg -lpng requiring -lz) in
+ the code run phase of library probing.
+
+Imager 0.75_02 - 07 Aug 2010
+==============
+
+Bug fixes:
+
+ - add file missing from MANIFEST, which was causing TIFF failures.
+
+Imager 0.75_01 - 06 Aug 2010
+==============
+
+Test release for the new PNG probe.
+
+ - added the ability to read multiple-image PNM files.
+ Note that unlike the pbm/pgm/ppm specification this accepts mixed
+ format files and allows white space padding between files.
+ Thanks to Philip Gwyn (Leolo) for this patch.
+
+ - moved the PNG file handling code into a sub-module in preparation
+ for separate distribution.
+ https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
+ Also helps avoid complications from -I/-L compile/link options from
+ other libraries.
+
+Bugs:
+
+ - Imager->new(data => $data) didn't try to process image file data in
+ $data
+ https://rt.cpan.org/Ticket/Display.html?id=58761
+
+ - t/t50basicoo.t no longer depends on the other tests to generate its
+ input files.
+ https://rt.cpan.org/Ticket/Display.html?id=9798
+ Also, it wasn't testing pnm (pnm vs ppm mix-up)
+
+ - update the documentation of hardinvert to match the change in 0.62.
+ https://rt.cpan.org/Ticket/Display.html?id=59785
+
+ - added hardinvertall filter which also inverts the alpha channel
+ (sorry for the mess)
+
+ - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
+ the probe can find the library for the test run.
+ https://rt.cpan.org/Ticket/Display.html?id=57518
+
+Imager 0.75 - 20 Jun 2010
+===========
+
+ - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
+ perls (not measured)
+
+Bugs:
+
+ - an opacity fill based on a fountain fill would segfault when
+ filling an 8-bit/sample image.
+
+ - merge thickline branch polygon fix
+ https://rt.cpan.org/Ticket/Display.html?id=43518
+
+Imager 0.74 - 7 May 2010
+===========
+
+Bug fixes:
+
+ - read_multi() didn't handle a missing file format library correctly,
+ aborting on failing to call i_readgif_multi_wiol() or
+ i_readtiff_multi_wiol().
+
+ - fix spelling errors patched by Debian
+ http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
+
+ - add an (unshipped) author test to spellcheck Imager's POD.
+
+ - update the TIFF file format documentation
+ https://rt.cpan.org/Ticket/Display.html?id=56510
+
+ - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
+
+Imager 0.73 - 15 Mar 2010
+===========
+
+ - implement outline circles, both anti-aliased and not
+ https://rt.cpan.org/Ticket/Display.html?id=19755
+
+ - a combine => "none" fill to a 1 or 3 channel image would produce
+ the incorrect colour.
+
+Imager 0.72 - 09 Dec 2009
+===========
+
+Bump version for release, since 0.71_03 is stable with CPAN testers.
+
+Imager 0.71_03 - 5 Dec 2009
+==============
+
+ - further adjust the threads test so it only performs the tests on
+ perls where it's expected to work, and only if the threads module
+ can be loaded.
+
+Imager 0.71_02 - 1 Dec 2009
+==============
+
+ - adjust the way we load the threads module for the threads test so
+ it works with non-threaded perls
+
+Imager 0.71_01 - 30 Nov 2009
+===========
+
+Bug fixes:
+
+ - use scanline oriented operations to flip images instead of pixel
+ operations
+ https://rt.cpan.org/Ticket/Display.html?id=39278
+
+ - use double/sample operations to flip large sample images instead of
+ 8-bit sample operations.
+ https://rt.cpan.org/Ticket/Display.html?id=39280
+
+ - fix POD nits
+ https://rt.cpan.org/Ticket/Display.html?id=51874
+
+ - prevent double-frees when someone creates Imager objects and then
+ creates a thread. Note: this just handles some simple cases,
+ Imager doesn't support perl threads, and isn't likely to.
+ https://rt.cpan.org/Ticket/Display.html?id=52268
+
+Imager 0.71 - 16 Nov 2009
+===========
+
+ - add the opacity fill type - an adaptor that modifies the opacity of
+ another fill.
+
+Bug fixes:
+
+ - the conv filter now enforces that the sum of the coefficients is
+ non-zero. Also, rather than skipping pixels off the edge off the
+ edge of the image, the closest edge pixel is used. Previously
+ dividing by the zero sum of coefficients could cause invalid
+ results or runtime exceptions.
+ Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
+ this bug.
+
+Imager 0.70 - 21 Sep 2009
+===========
+
+Bug fixes:
+
+ - release image row and comments memory on all error returns in gif
+ reader
+
+ - handle zero length extensions, previously this would cause a null
+ pointer dereference
+ Thanks to Krzysztof WojtaÅ for the test data and fix for this.
+
+ - an integer division meant that preview scaling to below 1 pixel
+ wide or high (which isn't too useful anyway) was calculating using
+ NaNs on most platforms, and causing an exception on others.
+ Thanks to David Cantrell for producing a backtrace of the crash on
+ his Alpha-NetBSD CPAN test box which made it possible to track this
+ down.
+
+Imager 0.69 - 08 Sep 2009
+===========
+
+Bug fixes:
+
+ - broken test fix - was attempting to call a function skip_all, when
+ that should be a parameter to plan().
+
+ - briefly document apidocs.perl, the tool used to build
+ Imager::APIRef and make some minor enhancements
+
+ - various minor documentation enhancements and fixes.
+
+Imager 0.68 - 07 Sep 2009
+===========
+
+ - Imager->new(file => $filename) and other similar incantations will
+ load the given file.
+ https://rt.cpan.org/Ticket/Display.html?id=48261
+
+Bug fixes:
+
+ - avoid using CHECK as a label in Imager::Test
+ http://nntp.x.perl.org/group/perl.cpan.testers/5220921
+
+ - re-work most image file test files that require a library into
+ separate library present/not present files to remove stupidly long
+ conditionals
+
+ - don't treat rubthrough() outside the bounds of the target image as
+ an error.
+ http://nntp.x.perl.org/group/perl.cpan.testers/5185716
+
+Imager 0.67_01 - 02 Sep 2009
+==============
+
+Bug fixes:
+
+ - correct documentation of default of raw image interleave read
+ parameter
+ https://rt.cpan.org/Ticket/Display.html?id=42074
+
+ - add raw_ prefix to raw read parameters, though the original names
+ still work.
+
+ - fail the read if an invalid raw_interleave parameter is supplied
+
+ - warn if no interleave or raw_interleave parameter is supplied,
+ since the documented default was wrong, and incompatible with the
+ write format
+
+ - for reading raw images, if raw_storechannels > raw_datachannels,
+ set the extra channels in the image to 0
+
+ - when probing for executables like freetype-config, search for .bat
+ and .cmd on MSWin32, as well as .exe.
+ https://rt.cpan.org/Ticket/Display.html?id=49275
+
+ - re-work the external libraries section of README:
+ - list Debian and Redhat package names for each library
+ - reformatting
+ - update URLs
+
+ - use the new EU::MM META_MERGE facility instead of generating
+ META.yml from scratch
+ https://rt.cpan.org/Ticket/Display.html?id=47888
+
+ - use Devel::CheckLib (bundled, modified) to check which release of
+ libtiff is installed and reject 3.9.0
+ http://bugzilla.maptools.org/show_bug.cgi?id=2088
+ http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
+
+Imager 0.67 - 12 Dec 2008
+===========
+
+Bug fixes:
+
+ - fix a packaging error
+
+Imager 0.66 - 12 Dec 2008
+===========
+
+ - 24-bit color .ICO/.CUR files can now be read.
+
+Bug fixes:
+
+ - an optimization skipping 0 src alpha values could cause the
+ rubthrough() to read past the end of a buffer.
+ http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
+
+ - corrected a reference leak where writing GIFs would leak memory.
+ This could also happen calling to_paletted().
+ Also documented the underlying long existing feature where the
+ colors parameter is filled with the generated color table and added
+ tests for it.
+ http://rt.cpan.org/Ticket/Display.html?id=41028
+
+ - write out the image size in bytes field of a BMP correctly.
+ http://rt.cpan.org/Ticket/Display.html?id=41406
+
+ - add limited tests for Imager::ExtUtils
+
+ - make Imager::ExtUtils->includes use an absolute path, since
+ a relative path could cause failures using Inline::C.
+ http://rt.cpan.org/Ticket/Display.html?id=37353
+
+ - re-arrange the POD for Imager::Font::BBox:
+ - mark total_width(), pos_width(), end_offset() obsolete, since
+ they're mostly for backwards compatibility
+ - group width methods and height methods
+ https://rt.cpan.org/Ticket/Display.html?id=39999
+
+Imager 0.65 - 20 May 2008
+===========
+
+Bug fixes:
+
+ - In some cases when an error occurs reading those parts of a JPEG
+ file after the image the scan-line buffer could be freed a second
+ time. In cases where the the error occured while reading the image
+ data it's possible that the buffer could have leaked.
+ Thanks to Gabriel Vasseur for reporting this and help in tracking
+ it down.
+
+ - the gif_screen_height tag was overriding the screen width and being
+ ignored for the screen height when present.
+ https://rt.cpan.org/Public/Bug/Display.html?id=35568
+
+Imager 0.64 - 23 April 2008
+===========
+
+This is a bug fix release. This includes a fix for a possible
+security issue.
+
+Bug fixes:
+
+ - Possible security issue: The floating point sample path for image
+ based fills had a buffer overflow. This would overwrite the end of
+ a malloc()ed buffer with double precision floats.
+ http://rt.cpan.org/Ticket/Display.html?id=35324
+ CVE-2008-1928
+
+ - check that the result of fileno($fh) is defined rather than simply
+ true when read() or write() is supplied with an fh parameter.
+ http://rt.cpan.org/Ticket/Display.html?id=35139
+
+ - i_scale_axis() wasn't checking the result of i_img_new_ch()
+ resulting in a SIGSEGV when attempting to scale an image to a size
+ too large to fit in memory. This is a NULL pointer access issue,
+ not a buffer overflow.
+ Added a check for the failure.
+ scale_calculate() (and hence scale()) will now fail if any of the
+ scale size parameters are a reference.
+ http://rt.cpan.org/Ticket/Display.html?id=35172
+
+ - Regression: filling a greyscale image with a hatch used the wrong
+ color channels from the supplied fg/bg colors.
+ https://rt.cpan.org/Ticket/Display.html?id=35278
+
+ - fixed a related problem for image fills.
+
+Imager 0.63 - 7 April 2008
+===========
+
+This release primarily contains changes to improve ease of use -
+rather than you having to convert images to the appropriate number of
+channels, Imager handles it internally. How to handle drawing colors
+and the default combine mode is a thornier problem left for some other
+release.
+
+ - the font libraries are now only initialized when needed.
+ http://rt.cpan.org/Ticket/Display.html?id=28825
+
+ - moved the imtoc.perl code into Imager::Preprocess
+
+ - paste() and rubthrough() now adapt the source image data to the
+ destination, so you can now safely paste/rubthrough from greyscale
+ images to color images or back, or from alpha channel images to
+ noalpha channels or back.
+ https://rt.cpan.org/Ticket/Display.html?id=30908
+
+ - rubthrough() now falls back to pasting when the source doesn't have
+ an alpha channel. This effectively treats the source as having a
+ max alpha channel, the right thing to do.
+ http://rt.cpan.org/Ticket/Display.html?id=29944
+
+ - re-worked most of the area filling code to use a common set of
+ functions when filling.
+ Corrected normal combine mode.
+ Rewrote most of the combine modes to match the way the SVG draft
+ defines them with respect to a translucent source and destination.
+ Added tests for translucent source and destination.
+ Added tests to check 8-bit/sample and double/sample combines work
+ similarly.
+ https://rt.cpan.org/Ticket/Display.html?id=29879
+
+ - writing a 2 or 4 channel image to a JPEG file will now write that
+ image as if composited against a background, black by default,
+ overridable with the i_background tag/parameter.
+ https://rt.cpan.org/Ticket/Display.html?id=29876
+
+ - writing a 2 or 4 channel image to a PGM/PPM file will now write
+ that image as if composited against a background, black by default,
+ overridable with the i_background tag/parameter.
+ http://rt.cpan.org/Ticket/Display.html?id=30074
+
+ - writing a 2 or 4 channel image to a BMP file will now write that
+ image as if composited against a background, black by default,
+ overridable with the i_background tag/parameter.
+ http://rt.cpan.org/Ticket/Display.html?id=30075
+
+Bug fixes:
+
+ - Imager::Matrix2d->translate() now only requires one of the x or y
+ parameters.
+ http://rt.cpan.org/Ticket/Display.html?id=29937
+
+ - mixing qtype scaling now sets all channels of a pixel to zero if
+ the pixel has zero coverage (zero alpha). This should produce more
+ compressible output files.
+ http://rt.cpan.org/Ticket/Display.html?id=32324
+
+ - removed the pointless #! line from lib/Imager/Font/Wrap.pm
+ Noticed when I saw:
+ https://bugzilla.redhat.com/show_bug.cgi?id=166254
+ I'm not changing the #! lines of the sample code, since it's sample
+ code, not intended for installation.
+ http://rt.cpan.org/Ticket/Display.html?id=33408
+
+ - some TGA images weren't being detected correctly as TGA images
+ https://rt.cpan.org/Ticket/Display.html?id=32925
+
+ - handling of the left-over bit for 16-bit/pixel TGA images has been
+ changed to match the behaviour of the GIMP. Previously the bit
+ being set was treated as an opaque pixel, but one user reported a
+ problem with loading such an image. I haven't been able to find any
+ tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
+ I'll match it's behaviour. See issue 114913 in the GIMP's
+ bugzilla.
+ http://rt.cpan.org/Ticket/Display.html?id=32926
+
+Imager 0.62 - 10 December 2007
+===========
+
+ - Makefile.PL now expands ~/path supplied to --incpath or --libpath
+ to /path under your home directory.
+ http://rt.cpan.org/Ticket/Display.html?id=29484
+
+ - the old dynaload code used Mach API functions to load dynamic
+ libraries on Mac OS X. These APIs have been deprecated in OS X
+ 10.5 and were causing some build problems.
+ So henceforth Imager uses the dlopen() family of functions, and you
+ will need version 10.3 or later of OS X.
+
+ - added the det() function to the transform2() engine.
+ added the sample quad_to_square.pl
+ Courtesy Richard Fairhurst.
+ http://rt.cpan.org/Ticket/Display.html?id=31244
+
+Bug fixes:
+
+ - samples/gifscale.pl sourced the base value for gif_top from
+ gif_left.
+ Thanks to Eleneldil G. Arilou for pointing this out.
+
+ - t/t82inline.t no longer loads B at runtime, to work around a bug
+ in some 5.005_0[45] installations.
+ http://rt.cpan.org/Ticket/Display.html?id=30508
+
+ - work around Module::Depends::Intrusive bug #21229
+ http://rt.cpan.org/Ticket/Display.html?id=30520
+
+ - the hardinvert filter no-longer inverts the alpha channel.
+ http://rt.cpan.org/Ticket/Display.html?id=30002
+
+ - the hardinvert filter now supports large samples
+
