173c91ba 159 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
160 used for color translation on Unix-like systems, and the fix
161 improves performance of supplying colors by name by about 80 times.
162 Test code that managed 3400 10x10 pixel boxes/second sped up to
163 25700 boxes/second.

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

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

528This release primarily contains changes to improve ease of use -
529rather than you having to convert images to the appropriate number of
530channels, Imager handles it internally. How to handle drawing colors
531and the default combine mode is a thornier problem left for some other
532release.

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

595
596 - handling of the left-over bit for 16-bit/pixel TGA images has been
597 changed to match the behaviour of the GIMP. Previously the bit
598 being set was treated as an opaque pixel, but one user reported a
599 problem with loading such an image. I haven't been able to find any
600 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
601 I'll match it's behaviour. See issue 114913 in the GIMP's
602 bugzilla.

895 - fix rendering on alpha channel images for the FreeType 2.x driver
896 http://rt.cpan.org/Ticket/Display.html?id=11972
897
898 - reading bmp files now consitently handles short reads. You can now
899 supply a parameter to treat a short read as successful and set
900 i_incomplete
901 http://rt.cpan.org/Ticket/Display.html?id=8426
902
903 - previously, reading ASCII PBM files required spaces between samples,
904 even though the format doesn't require that

906 - improved documentation of the unsharpmask filter (I hope)
907 http://rt.cpan.org/Ticket/Display.html?id=25531
908
909 - force flushing of the output from i_tt_dump_names() and test output
910 in t/t35ttfont.t to prevent output from being mixed up.

912
913 - rewrite a conditional expression as an if() to hopefully work around
914 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.

920Imager 0.55 - 16 Dec 2006
921===========
922
923This is primarily a bug fix release.
924
925Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
926
927There is one new feature:
928
929 - the Win32 font driver now supports UTF8 (RT 22166)
930 http://www.cpanforum.com/threads/3276
931 http://rt.cpan.org/Ticket/Display.html?id=22166
932
933Several bugs were fixed:
934
935 - the string() method would not output the string "0"
936 http://rt.cpan.org/Public/Bug/Display.html?id=21770
937
938 - fills.c was failing to compile on Solaris 10 (compiler unknown)
939 http://rt.cpan.org/Public/Bug/Display.html?id=21944
940
941 - the gif_disposal and gif_user_input tags weren't being read from
942 the file correctly
943 http://rt.cpan.org/Public/Bug/Display.html?id=22192
944
945 - gif.c was failing to build under MSVC
946 http://rt.cpan.org/Ticket/Display.html?id=23922
947
948 - in some cases strings passed to the string() method were treated as
949 terminated by NUL (chr 0)
950 http://rt.cpan.org/Public/Bug/Display.html?id=21770
951
952 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
953 that's the default build name for zlib on Win32.
954 http://rt.cpan.org/Ticket/Display.html?id=23064
955
956 - search $Config{incpath} for headers too, which we should have been
957 doing all along.
958
959Win32 font driver fixes:
960
961 - the global descent value from bounding box was the wrong sign
962 http://www.cpanforum.com/threads/3276
963
964 - if the first or last glyph overflowed the left or right side of the
965 advance width they would be clipped
966
967
968Imager 0.54 - 14 Sep 2006
969===========
970
971This is primarily a feature release:
972
973 - a new qtype value 'mixing' has been added to the scale()
974 method. This is faster than 'normal', slower than 'preview'. This
975 is based on the method used by pnmscale, and seems to produce less
976 blurry results than normal.
977 http://rt.cpan.org/Public/Bug/Display.html?id=20677
978
979 - the rubthrough() method can now render onto images with an alpha
980 channel.
981 http://rt.cpan.org/Ticket/Display.html?id=20678
982
983 - the read_multi() method now falls back to calling doing a single
984 image read via the read() method and write_multi() will now fall
985 back to calling write() if a single image is supplied. This means
986 you can simply call the read_multi() or write_multi() functions
987 without having to check if the type is formatted by that method.
988 http://rt.cpan.org/Ticket/Display.html?id=19457
989 http://rt.cpan.org/Ticket/Display.html?id=19458
990
991 - the GIF loop extension can now be written. If you don't have
992 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
993 should upgrade.
994 http://rt.cpan.org/Ticket/Display.html?id=21185
995
996 - getscanline() and setscanline() can now read/write palette index
997 based data from/to the image for paletted images, by setting type to
998 'index'.
999 http://rt.cpan.org/Ticket/Display.html?id=20338
1000
1001 - we no longer hassle you to disable GIF support
1002 http://rt.cpan.org/Ticket/Display.html?id=20687
1003
1004 - minor documentation fixes
1005
1006
1007Imager 0.53 - 26 Jul 2006
1008===========
1009
1010This is a bugfix release.
1011
1012Some test code was left in a code path not covered by the test
1013suite. A test was added to cover this code path and the test code was
1014removed.
1015http://rt.cpan.org/Public/Bug/Display.html?id=20705
1016
1017
1018Imager 0.52 - 25 Jul 2006
1019===========
1020
1021This is primarily a feature release, but contains a fair few bug
1022fixes, new features:
1023
1024 - ability to read and write MS Windows ICO and CUR files
1025
1026 - you can now add file format plugins to support new file formats
1027
1028 - add POD coverage tests
1029
1030 - setcolors() and addcolors() now accept color names and so on
1031 instead of requiring Imager::Color objects.
1032 http://rt.cpan.org/Ticket/Display.html?id=20056
1033
1034 - flood_fill() can now fill to a specified border color instead of
1035 just to the area the same color as the seed.
1036 http://rt.cpan.org/Ticket/Display.html?id=19618
1037
1038
1039Bug fixes:
1040
1041 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1042 calculating the advance width.
1043 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1044
1045 - bounding_box for the T1 driver wasn't including leading and
1046 trailing spaces in the bounding box as the other drivers did, it also
1047 produced strange results for empty strings or strings containing only
1048 spaces
1049
1050 - when reading CMYK jpeg images they were being transferred to the
1051 image object as is, producing a four channel image. It only looked ok
1052 due to an old still unfixed Photoshop bug. We now convert from the
1053 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1054 http://rt.cpan.org/Ticket/Display.html?id=20416
1055
1056 - reading a CYMK TIFF would result in a 4 channel image, reading any
1057 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1058 result in an error.
1059 http://rt.cpan.org/Ticket/Display.html?id=20415
1060
1061 - added /usr/local/include to the default include search path, since
1062 we were already searching /usr/local/lib for libraries.
1063
1064And various minor fixes and documentation updates.
1065
1066
1067Imager 0.51 - 23 Apr 2006

1071 a crash
1072 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1073
1074 - fix mis-processing of the src_maxx and src_maxy parameters of the
1075 paste() method
1076 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1077
1078 - fix a problem in Imager's "smart" handling of the color parameter
1079 to various methods.
1080 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1081
1082
1083Imager 0.50 - 29 Mar 2006
1084===========
1085
1086 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1087 or 4 channel image to jpeg or a 2 channel image to tga where the
1088 output is an in-memeory buffer.
1089 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1090
1091 - fixes an incorrect pointer parameter in the PNG code
1092 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1093
1094 - skip Inline::C tests when building in a directory with spaces
1095 http://rt.cpan.org/Public/Bug/Display.html?id=18049
