Imager release history. Older releases can be found in Changes.old
-Imager 0.63 - unreleased
+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
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
