25Bug fixes:
26
27 - Imager::Probe was calling ExtUtils::Liblist to initialize
28 LD_RUN_PATH supplying an undefined value rather than the found
29 directory. Thanks to Justin Davis.

93 - added the ability to read multiple-image PNM files.
94 Note that unlike the pbm/pgm/ppm specification this accepts mixed

212Bug fixes:
213
214 - the conv filter now enforces that the sum of the coefficients is
215 non-zero. Also, rather than skipping pixels off the edge off the
216 edge of the image, the closest edge pixel is used. Previously
217 dividing by the zero sum of coefficients could cause invalid
218 results or runtime exceptions.
219 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
220 this bug.

234 - an integer division meant that preview scaling to below 1 pixel
235 wide or high (which isn't too useful anyway) was calculating using
236 NaNs on most platforms, and causing an exception on others.
237 Thanks to David Cantrell for producing a backtrace of the crash on
238 his Alpha-NetBSD CPAN test box which made it possible to track this
239 down.

288 - warn if no interleave or raw_interleave parameter is supplied,
289 since the documented default was wrong, and incompatible with the

387 - i_scale_axis() wasn't checking the result of i_img_new_ch()
388 resulting in a SIGSEGV when attempting to scale an image to a size
389 too large to fit in memory. This is a NULL pointer access issue,
390 not a buffer overflow.
391 Added a check for the failure.

405This release primarily contains changes to improve ease of use -
406rather than you having to convert images to the appropriate number of
407channels, Imager handles it internally. How to handle drawing colors
408and the default combine mode is a thornier problem left for some other
409release.

TC
414 - moved the imtoc.perl code into Imager::Preprocess
415
416 - paste() and rubthrough() now adapt the source image data to the
417 destination, so you can now safely paste/rubthrough from greyscale
418 images to color images or back, or from alpha channel images to
419 noalpha channels or back.
420 https://rt.cpan.org/Ticket/Display.html?id=30908
421
422 - rubthrough() now falls back to pasting when the source doesn't have
423 an alpha channel. This effectively treats the source as having a
424 max alpha channel, the right thing to do.
425 http://rt.cpan.org/Ticket/Display.html?id=29944
426
427 - re-worked most of the area filling code to use a common set of
428 functions when filling.
429 Corrected normal combine mode.
430 Rewrote most of the combine modes to match the way the SVG draft
431 defines them with respect to a translucent source and destination.
432 Added tests for translucent source and destination.
433 Added tests to check 8-bit/sample and double/sample combines work
434 similarly.

466 I'm not changing the #! lines of the sample code, since it's sample

470 - some TGA images weren't being detected correctly as TGA images
471 https://rt.cpan.org/Ticket/Display.html?id=32925
472
473 - handling of the left-over bit for 16-bit/pixel TGA images has been
474 changed to match the behaviour of the GIMP. Previously the bit
475 being set was treated as an opaque pixel, but one user reported a
476 problem with loading such an image. I haven't been able to find any
477 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
478 I'll match it's behaviour. See issue 114913 in the GIMP's
479 bugzilla.

489 - the old dynaload code used Mach API functions to load dynamic
490 libraries on Mac OS X. These APIs have been deprecated in OS X
491 10.5 and were causing some build problems.
492 So henceforth Imager uses the dlopen() family of functions, and you
493 will need version 10.3 or later of OS X.

801
802Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
803
804There is one new feature:
805
806 - the Win32 font driver now supports UTF8 (RT 22166)
807 http://www.cpanforum.com/threads/3276
808 http://rt.cpan.org/Ticket/Display.html?id=22166
809
810Several bugs were fixed:
811
812 - the string() method would not output the string "0"
813 http://rt.cpan.org/Public/Bug/Display.html?id=21770
814
815 - fills.c was failing to compile on Solaris 10 (compiler unknown)
816 http://rt.cpan.org/Public/Bug/Display.html?id=21944
817
818 - the gif_disposal and gif_user_input tags weren't being read from
819 the file correctly
820 http://rt.cpan.org/Public/Bug/Display.html?id=22192
821
822 - gif.c was failing to build under MSVC
823 http://rt.cpan.org/Ticket/Display.html?id=23922
824
825 - in some cases strings passed to the string() method were treated as
826 terminated by NUL (chr 0)
827 http://rt.cpan.org/Public/Bug/Display.html?id=21770
828
829 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
830 that's the default build name for zlib on Win32.
831 http://rt.cpan.org/Ticket/Display.html?id=23064
832
833 - search $Config{incpath} for headers too, which we should have been
834 doing all along.
835
836Win32 font driver fixes:
837
838 - the global descent value from bounding box was the wrong sign
839 http://www.cpanforum.com/threads/3276
840
841 - if the first or last glyph overflowed the left or right side of the
842 advance width they would be clipped
843
844
845Imager 0.54 - 14 Sep 2006
846===========
847
848This is primarily a feature release:
849
850 - a new qtype value 'mixing' has been added to the scale()
851 method. This is faster than 'normal', slower than 'preview'. This
852 is based on the method used by pnmscale, and seems to produce less
853 blurry results than normal.
854 http://rt.cpan.org/Public/Bug/Display.html?id=20677
855
856 - the rubthrough() method can now render onto images with an alpha
857 channel.
858 http://rt.cpan.org/Ticket/Display.html?id=20678
859
860 - the read_multi() method now falls back to calling doing a single
861 image read via the read() method and write_multi() will now fall
862 back to calling write() if a single image is supplied. This means
863 you can simply call the read_multi() or write_multi() functions
864 without having to check if the type is formatted by that method.
865 http://rt.cpan.org/Ticket/Display.html?id=19457
866 http://rt.cpan.org/Ticket/Display.html?id=19458
867
868 - the GIF loop extension can now be written. If you don't have
869 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
870 should upgrade.
871 http://rt.cpan.org/Ticket/Display.html?id=21185
872
873 - getscanline() and setscanline() can now read/write palette index
874 based data from/to the image for paletted images, by setting type to
875 'index'.
876 http://rt.cpan.org/Ticket/Display.html?id=20338
877
878 - we no longer hassle you to disable GIF support
879 http://rt.cpan.org/Ticket/Display.html?id=20687
880
881 - minor documentation fixes
882
883
884Imager 0.53 - 26 Jul 2006
885===========
886
887This is a bugfix release.
888
889Some test code was left in a code path not covered by the test
890suite. A test was added to cover this code path and the test code was
891removed.

904

908 instead of requiring Imager::Color objects.
909 http://rt.cpan.org/Ticket/Display.html?id=20056
910
911 - flood_fill() can now fill to a specified border color instead of
912 just to the area the same color as the seed.
913 http://rt.cpan.org/Ticket/Display.html?id=19618
914
915
916Bug fixes:
917
918 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
919 calculating the advance width.

921
922 - bounding_box for the T1 driver wasn't including leading and
923 trailing spaces in the bounding box as the other drivers did, it also
924 produced strange results for empty strings or strings containing only
925 spaces
926
927 - when reading CMYK jpeg images they were being transferred to the
928 image object as is, producing a four channel image. It only looked ok
929 due to an old still unfixed Photoshop bug. We now convert from the
930 inverted CMYK that photoshop (and Corel for example) produce into RGB.

933 - reading a CYMK TIFF would result in a 4 channel image, reading any
934 image with more than 4 channels (eg. RGB with 2 alpha channels) would
935 result in an error.

938 - added /usr/local/include to the default include search path, since
