354 - the conv filter now enforces that the sum of the coefficients is
355 non-zero. Also, rather than skipping pixels off the edge off the
356 edge of the image, the closest edge pixel is used. Previously
357 dividing by the zero sum of coefficients could cause invalid
358 results or runtime exceptions.
359 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
360 this bug.

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

545This release primarily contains changes to improve ease of use -
546rather than you having to convert images to the appropriate number of
547channels, Imager handles it internally. How to handle drawing colors
548and the default combine mode is a thornier problem left for some other
549release.

554 - moved the imtoc.perl code into Imager::Preprocess
555
556 - paste() and rubthrough() now adapt the source image data to the
557 destination, so you can now safely paste/rubthrough from greyscale
558 images to color images or back, or from alpha channel images to
559 noalpha channels or back.
560 https://rt.cpan.org/Ticket/Display.html?id=30908
561
562 - rubthrough() now falls back to pasting when the source doesn't have
563 an alpha channel. This effectively treats the source as having a
564 max alpha channel, the right thing to do.
565 http://rt.cpan.org/Ticket/Display.html?id=29944
566
567 - re-worked most of the area filling code to use a common set of
568 functions when filling.
569 Corrected normal combine mode.
570 Rewrote most of the combine modes to match the way the SVG draft
571 defines them with respect to a translucent source and destination.
572 Added tests for translucent source and destination.
573 Added tests to check 8-bit/sample and double/sample combines work
574 similarly.

613 - handling of the left-over bit for 16-bit/pixel TGA images has been
614 changed to match the behaviour of the GIMP. Previously the bit
615 being set was treated as an opaque pixel, but one user reported a
616 problem with loading such an image. I haven't been able to find any
617 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
618 I'll match it's behaviour. See issue 114913 in the GIMP's
619 bugzilla.

905Bug fixes:
906
907 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
908 was returning an image object with an extra reference, this
909 resulted in a memory leak.
910 http://rt.cpan.org/Ticket/Display.html?id=24992
911
912 - fix rendering on alpha channel images for the FreeType 2.x driver
913 http://rt.cpan.org/Ticket/Display.html?id=11972
914
915 - reading bmp files now consitently handles short reads. You can now
916 supply a parameter to treat a short read as successful and set
917 i_incomplete
918 http://rt.cpan.org/Ticket/Display.html?id=8426
919
920 - previously, reading ASCII PBM files required spaces between samples,
921 even though the format doesn't require that

923 - improved documentation of the unsharpmask filter (I hope)
924 http://rt.cpan.org/Ticket/Display.html?id=25531

929
930 - rewrite a conditional expression as an if() to hopefully work around
931 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.

937Imager 0.55 - 16 Dec 2006
938===========
939
940This is primarily a bug fix release.
941
942Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
943
944There is one new feature:
945
946 - the Win32 font driver now supports UTF8 (RT 22166)
947 http://www.cpanforum.com/threads/3276
948 http://rt.cpan.org/Ticket/Display.html?id=22166
949
950Several bugs were fixed:
951
952 - the string() method would not output the string "0"
953 http://rt.cpan.org/Public/Bug/Display.html?id=21770
954
955 - fills.c was failing to compile on Solaris 10 (compiler unknown)
956 http://rt.cpan.org/Public/Bug/Display.html?id=21944
957
958 - the gif_disposal and gif_user_input tags weren't being read from
959 the file correctly
960 http://rt.cpan.org/Public/Bug/Display.html?id=22192
961
962 - gif.c was failing to build under MSVC
963 http://rt.cpan.org/Ticket/Display.html?id=23922
964
965 - in some cases strings passed to the string() method were treated as
966 terminated by NUL (chr 0)
967 http://rt.cpan.org/Public/Bug/Display.html?id=21770
968
969 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
970 that's the default build name for zlib on Win32.
971 http://rt.cpan.org/Ticket/Display.html?id=23064
972
973 - search $Config{incpath} for headers too, which we should have been
974 doing all along.
975
976Win32 font driver fixes:
977
978 - the global descent value from bounding box was the wrong sign
979 http://www.cpanforum.com/threads/3276
980
981 - if the first or last glyph overflowed the left or right side of the
982 advance width they would be clipped
983
984
985Imager 0.54 - 14 Sep 2006
986===========
987
988This is primarily a feature release:
989
990 - a new qtype value 'mixing' has been added to the scale()
991 method. This is faster than 'normal', slower than 'preview'. This
992 is based on the method used by pnmscale, and seems to produce less
993 blurry results than normal.
994 http://rt.cpan.org/Public/Bug/Display.html?id=20677
995
996 - the rubthrough() method can now render onto images with an alpha
997 channel.
998 http://rt.cpan.org/Ticket/Display.html?id=20678
999
1000 - the read_multi() method now falls back to calling doing a single
1001 image read via the read() method and write_multi() will now fall
1002 back to calling write() if a single image is supplied. This means
1003 you can simply call the read_multi() or write_multi() functions
1004 without having to check if the type is formatted by that method.
1005 http://rt.cpan.org/Ticket/Display.html?id=19457
1006 http://rt.cpan.org/Ticket/Display.html?id=19458
1007
1008 - the GIF loop extension can now be written. If you don't have
1009 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1010 should upgrade.
1011 http://rt.cpan.org/Ticket/Display.html?id=21185
1012
1013 - getscanline() and setscanline() can now read/write palette index
1014 based data from/to the image for paletted images, by setting type to
1015 'index'.
1016 http://rt.cpan.org/Ticket/Display.html?id=20338
1017
1018 - we no longer hassle you to disable GIF support
1019 http://rt.cpan.org/Ticket/Display.html?id=20687
1020
1021 - minor documentation fixes
1022
1023
1024Imager 0.53 - 26 Jul 2006
1025===========
1026
1027This is a bugfix release.
1028
1029Some test code was left in a code path not covered by the test
1030suite. A test was added to cover this code path and the test code was
1031removed.
1032http://rt.cpan.org/Public/Bug/Display.html?id=20705
1033
1034
1035Imager 0.52 - 25 Jul 2006
1036===========
1037
1038This is primarily a feature release, but contains a fair few bug
1039fixes, new features:
1040
1041 - ability to read and write MS Windows ICO and CUR files
1042
1043 - you can now add file format plugins to support new file formats
1044
1045 - add POD coverage tests
1046
1047 - setcolors() and addcolors() now accept color names and so on
1048 instead of requiring Imager::Color objects.
1049 http://rt.cpan.org/Ticket/Display.html?id=20056
1050
1051 - flood_fill() can now fill to a specified border color instead of
1052 just to the area the same color as the seed.
1053 http://rt.cpan.org/Ticket/Display.html?id=19618
1054
1055
1056Bug fixes:
1057
1058 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1059 calculating the advance width.
1060 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1061
1062 - bounding_box for the T1 driver wasn't including leading and
1063 trailing spaces in the bounding box as the other drivers did, it also
1064 produced strange results for empty strings or strings containing only
1065 spaces
1066
1067 - when reading CMYK jpeg images they were being transferred to the
1068 image object as is, producing a four channel image. It only looked ok
1069 due to an old still unfixed Photoshop bug. We now convert from the
1070 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1071 http://rt.cpan.org/Ticket/Display.html?id=20416
1072
1073 - reading a CYMK TIFF would result in a 4 channel image, reading any
1074 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1075 result in an error.
1076 http://rt.cpan.org/Ticket/Display.html?id=20415
1077
1078 - added /usr/local/include to the default include search path, since
1079 we were already searching /usr/local/lib for libraries.
1080
1081And various minor fixes and documentation updates.
1082
1083
1084Imager 0.51 - 23 Apr 2006

1088 a crash
1089 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1090
1091 - fix mis-processing of the src_maxx and src_maxy parameters of the
1092 paste() method
1093 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1094
1095 - fix a problem in Imager's "smart" handling of the color parameter

1105 output is an in-memeory buffer.
1106 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1107
1108 - fixes an incorrect pointer parameter in the PNG code
1109 http://rt.cpan.org/Public/Bug/Display.html?id=18051
