329Bug fixes:
330
331 - the conv filter now enforces that the sum of the coefficients is
332 non-zero. Also, rather than skipping pixels off the edge off the
333 edge of the image, the closest edge pixel is used. Previously
334 dividing by the zero sum of coefficients could cause invalid
335 results or runtime exceptions.
336 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
337 this bug.

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

504 - i_scale_axis() wasn't checking the result of i_img_new_ch()
505 resulting in a SIGSEGV when attempting to scale an image to a size
506 too large to fit in memory. This is a NULL pointer access issue,
507 not a buffer overflow.

522This release primarily contains changes to improve ease of use -
523rather than you having to convert images to the appropriate number of
524channels, Imager handles it internally. How to handle drawing colors
525and the default combine mode is a thornier problem left for some other
526release.

TC
531 - moved the imtoc.perl code into Imager::Preprocess
532
533 - paste() and rubthrough() now adapt the source image data to the
534 destination, so you can now safely paste/rubthrough from greyscale
535 images to color images or back, or from alpha channel images to
536 noalpha channels or back.
537 https://rt.cpan.org/Ticket/Display.html?id=30908
538
539 - rubthrough() now falls back to pasting when the source doesn't have
540 an alpha channel. This effectively treats the source as having a
541 max alpha channel, the right thing to do.
542 http://rt.cpan.org/Ticket/Display.html?id=29944
543
544 - re-worked most of the area filling code to use a common set of
545 functions when filling.
546 Corrected normal combine mode.
547 Rewrote most of the combine modes to match the way the SVG draft
548 defines them with respect to a translucent source and destination.
549 Added tests for translucent source and destination.
550 Added tests to check 8-bit/sample and double/sample combines work
551 similarly.

588 https://rt.cpan.org/Ticket/Display.html?id=32925
589
590 - handling of the left-over bit for 16-bit/pixel TGA images has been
591 changed to match the behaviour of the GIMP. Previously the bit
592 being set was treated as an opaque pixel, but one user reported a
593 problem with loading such an image. I haven't been able to find any
594 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
595 I'll match it's behaviour. See issue 114913 in the GIMP's
596 bugzilla.

897 - previously, reading ASCII PBM files required spaces between samples,
898 even though the format doesn't require that

900 - improved documentation of the unsharpmask filter (I hope)
901 http://rt.cpan.org/Ticket/Display.html?id=25531
902
903 - force flushing of the output from i_tt_dump_names() and test output
904 in t/t35ttfont.t to prevent output from being mixed up.
905 https://rt.cpan.org/Ticket/Display.html?id=24859
906
907 - rewrite a conditional expression as an if() to hopefully work around
908 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
909 https://rt.cpan.org/Ticket/Display.html?id=25561
910
911 - avoid Data::Dumper in regops.perl to support older releases of perl

914Imager 0.55 - 16 Dec 2006
915===========
916
917This is primarily a bug fix release.
918
919Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
920
921There is one new feature:
922
923 - the Win32 font driver now supports UTF8 (RT 22166)
924 http://www.cpanforum.com/threads/3276
925 http://rt.cpan.org/Ticket/Display.html?id=22166
926
927Several bugs were fixed:
928
929 - the string() method would not output the string "0"
930 http://rt.cpan.org/Public/Bug/Display.html?id=21770
931
932 - fills.c was failing to compile on Solaris 10 (compiler unknown)
933 http://rt.cpan.org/Public/Bug/Display.html?id=21944
934
935 - the gif_disposal and gif_user_input tags weren't being read from
936 the file correctly
937 http://rt.cpan.org/Public/Bug/Display.html?id=22192
938
939 - gif.c was failing to build under MSVC
940 http://rt.cpan.org/Ticket/Display.html?id=23922
941
942 - in some cases strings passed to the string() method were treated as
943 terminated by NUL (chr 0)
944 http://rt.cpan.org/Public/Bug/Display.html?id=21770
945
946 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
947 that's the default build name for zlib on Win32.
948 http://rt.cpan.org/Ticket/Display.html?id=23064
949
950 - search $Config{incpath} for headers too, which we should have been
951 doing all along.
952
953Win32 font driver fixes:
954
955 - the global descent value from bounding box was the wrong sign
956 http://www.cpanforum.com/threads/3276
957
958 - if the first or last glyph overflowed the left or right side of the
959 advance width they would be clipped
960
961
962Imager 0.54 - 14 Sep 2006
963===========
964
965This is primarily a feature release:
966
967 - a new qtype value 'mixing' has been added to the scale()
968 method. This is faster than 'normal', slower than 'preview'. This
969 is based on the method used by pnmscale, and seems to produce less
970 blurry results than normal.
971 http://rt.cpan.org/Public/Bug/Display.html?id=20677
972
973 - the rubthrough() method can now render onto images with an alpha
974 channel.
975 http://rt.cpan.org/Ticket/Display.html?id=20678
976
977 - the read_multi() method now falls back to calling doing a single
978 image read via the read() method and write_multi() will now fall
979 back to calling write() if a single image is supplied. This means
980 you can simply call the read_multi() or write_multi() functions
981 without having to check if the type is formatted by that method.
982 http://rt.cpan.org/Ticket/Display.html?id=19457
983 http://rt.cpan.org/Ticket/Display.html?id=19458
984
985 - the GIF loop extension can now be written. If you don't have
986 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
987 should upgrade.
988 http://rt.cpan.org/Ticket/Display.html?id=21185
989
990 - getscanline() and setscanline() can now read/write palette index
991 based data from/to the image for paletted images, by setting type to
992 'index'.
993 http://rt.cpan.org/Ticket/Display.html?id=20338
994
995 - we no longer hassle you to disable GIF support
996 http://rt.cpan.org/Ticket/Display.html?id=20687
997
998 - minor documentation fixes
999
1000
1001Imager 0.53 - 26 Jul 2006
1002===========
1003
1004This is a bugfix release.
1005
1006Some test code was left in a code path not covered by the test
1007suite. A test was added to cover this code path and the test code was
1008removed.
1009http://rt.cpan.org/Public/Bug/Display.html?id=20705
1010
1011
1012Imager 0.52 - 25 Jul 2006
1013===========
1014
1015This is primarily a feature release, but contains a fair few bug
1016fixes, new features:
1017
1018 - ability to read and write MS Windows ICO and CUR files
1019
1020 - you can now add file format plugins to support new file formats
1021
1022 - add POD coverage tests
1023
1024 - setcolors() and addcolors() now accept color names and so on
1025 instead of requiring Imager::Color objects.
1026 http://rt.cpan.org/Ticket/Display.html?id=20056
1027
1028 - flood_fill() can now fill to a specified border color instead of
1029 just to the area the same color as the seed.
1030 http://rt.cpan.org/Ticket/Display.html?id=19618
1031
1032
1033Bug fixes:
1034
1035 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1036 calculating the advance width.
1037 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1038
1039 - bounding_box for the T1 driver wasn't including leading and
1040 trailing spaces in the bounding box as the other drivers did, it also
1041 produced strange results for empty strings or strings containing only
1042 spaces
1043
1044 - when reading CMYK jpeg images they were being transferred to the
1045 image object as is, producing a four channel image. It only looked ok
1046 due to an old still unfixed Photoshop bug. We now convert from the
1047 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1048 http://rt.cpan.org/Ticket/Display.html?id=20416
1049
1050 - reading a CYMK TIFF would result in a 4 channel image, reading any
1051 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1052 result in an error.
1053 http://rt.cpan.org/Ticket/Display.html?id=20415
1054
1055 - added /usr/local/include to the default include search path, since
1056 we were already searching /usr/local/lib for libraries.
1057
1058And various minor fixes and documentation updates.
1059
1060

1066 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1067
1068 - fix mis-processing of the src_maxx and src_maxy parameters of the
1069 paste() method
1070 http://rt.cpan.org/Public/Bug/Display.html?id=18712
