56===========
57
58Bug fixes:
59
60 - eliminate calls to i_has_format() from the test suite, since it's
61 no longer a useful way to check for file format support. Eliminate
62 i_has_format() from the functions exposed via XS.
63 https://rt.cpan.org/Ticket/Display.html?id=65863
64
7540f84a
TC
65 - eliminate calls to note(), which isn't in the (very old) version of
66 Test::More we have as a pre-requisite. note() is modern enough
67 that I don't feel a need to require a Test::More upgrade for it.
68 https://rt.cpan.org/Ticket/Display.html?id=65864

79 - increase the version of Imager::Font::Type1 so that upgrades don't
80 downgrade the version in this file.
81 https://rt.cpan.org/Ticket/Display.html?id=66250
82
83 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
84 that option for the directories that would normally go in
85 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

249 https://rt.cpan.org/Ticket/Display.html?id=60509
250
173c91ba 251 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
252 used for color translation on Unix-like systems, and the fix
253 improves performance of supplying colors by name by about 80 times.
254 Test code that managed 3400 10x10 pixel boxes/second sped up to
255 25700 boxes/second.

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

312
1d7e3124

416 - prevent double-frees when someone creates Imager objects and then
417 creates a thread. Note: this just handles some simple cases,
418 Imager doesn't support perl threads, and isn't likely to.

427Bug fixes:
428
429 - the conv filter now enforces that the sum of the coefficients is
430 non-zero. Also, rather than skipping pixels off the edge off the
431 edge of the image, the closest edge pixel is used. Previously
432 dividing by the zero sum of coefficients could cause invalid
433 results or runtime exceptions.
434 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
435 this bug.

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

620This release primarily contains changes to improve ease of use -
621rather than you having to convert images to the appropriate number of

623and the default combine mode is a thornier problem left for some other
624release.

629 - moved the imtoc.perl code into Imager::Preprocess

631 - paste() and rubthrough() now adapt the source image data to the

633 images to color images or back, or from alpha channel images to
634 noalpha channels or back.
635 https://rt.cpan.org/Ticket/Display.html?id=30908
636
637 - rubthrough() now falls back to pasting when the source doesn't have
638 an alpha channel. This effectively treats the source as having a
639 max alpha channel, the right thing to do.
640 http://rt.cpan.org/Ticket/Display.html?id=29944
641
642 - re-worked most of the area filling code to use a common set of
643 functions when filling.

645 Rewrote most of the combine modes to match the way the SVG draft
646 defines them with respect to a translucent source and destination.
647 Added tests for translucent source and destination.

649 similarly.

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

940 - reworked library probing, we can now set more than one probe
941 function for a library. Disabled the default (non-freetype-config)
942 library probe and added an extra probe function that searches for
943 both ft2build.h and whatever it includes, and adds -I as needed.
944 Hopefully this will fix build problems like

1012Imager 0.55 - 16 Dec 2006
1013===========
1014
1015This is primarily a bug fix release.
1016
1017Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1018
1019There is one new feature:
1020
1021 - the Win32 font driver now supports UTF8 (RT 22166)
1022 http://www.cpanforum.com/threads/3276
1023 http://rt.cpan.org/Ticket/Display.html?id=22166
1024
1025Several bugs were fixed:
1026
1027 - the string() method would not output the string "0"
1028 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1029
1030 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1031 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1032
1033 - the gif_disposal and gif_user_input tags weren't being read from
1034 the file correctly
1035 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1036
1037 - gif.c was failing to build under MSVC
1038 http://rt.cpan.org/Ticket/Display.html?id=23922
1039
1040 - in some cases strings passed to the string() method were treated as
1041 terminated by NUL (chr 0)
1042 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1043
1044 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1045 that's the default build name for zlib on Win32.
1046 http://rt.cpan.org/Ticket/Display.html?id=23064
1047
1048 - search $Config{incpath} for headers too, which we should have been
1049 doing all along.
1050
1051Win32 font driver fixes:
1052
1053 - the global descent value from bounding box was the wrong sign
1054 http://www.cpanforum.com/threads/3276
1055
1056 - if the first or last glyph overflowed the left or right side of the
1057 advance width they would be clipped
1058
1059
1060Imager 0.54 - 14 Sep 2006
1061===========
1062
1063This is primarily a feature release:
1064
1065 - a new qtype value 'mixing' has been added to the scale()
1066 method. This is faster than 'normal', slower than 'preview'. This
1067 is based on the method used by pnmscale, and seems to produce less
1068 blurry results than normal.
1069 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1070
1071 - the rubthrough() method can now render onto images with an alpha
1072 channel.
1073 http://rt.cpan.org/Ticket/Display.html?id=20678
1074
1075 - the read_multi() method now falls back to calling doing a single
1076 image read via the read() method and write_multi() will now fall
1077 back to calling write() if a single image is supplied. This means
1078 you can simply call the read_multi() or write_multi() functions
1079 without having to check if the type is formatted by that method.
1080 http://rt.cpan.org/Ticket/Display.html?id=19457
1081 http://rt.cpan.org/Ticket/Display.html?id=19458
1082
1083 - the GIF loop extension can now be written. If you don't have
1084 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1085 should upgrade.
1086 http://rt.cpan.org/Ticket/Display.html?id=21185
1087
1088 - getscanline() and setscanline() can now read/write palette index
1089 based data from/to the image for paletted images, by setting type to
1090 'index'.
1091 http://rt.cpan.org/Ticket/Display.html?id=20338
1092
1093 - we no longer hassle you to disable GIF support
1094 http://rt.cpan.org/Ticket/Display.html?id=20687
1095
1096 - minor documentation fixes
1097
1098
1099Imager 0.53 - 26 Jul 2006
1100===========
1101
1102This is a bugfix release.
1103
1104Some test code was left in a code path not covered by the test
1105suite. A test was added to cover this code path and the test code was
1106removed.
1107http://rt.cpan.org/Public/Bug/Display.html?id=20705
1108
1109
1110Imager 0.52 - 25 Jul 2006
1111===========
1112
1113This is primarily a feature release, but contains a fair few bug
1114fixes, new features:
1115
1116 - ability to read and write MS Windows ICO and CUR files
1117
1118 - you can now add file format plugins to support new file formats
1119
1120 - add POD coverage tests
1121
1122 - setcolors() and addcolors() now accept color names and so on
1123 instead of requiring Imager::Color objects.
1124 http://rt.cpan.org/Ticket/Display.html?id=20056
1125
1126 - flood_fill() can now fill to a specified border color instead of
1127 just to the area the same color as the seed.
1128 http://rt.cpan.org/Ticket/Display.html?id=19618
1129
1130
1131Bug fixes:
1132
1133 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1134 calculating the advance width.
1135 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1136
1137 - bounding_box for the T1 driver wasn't including leading and
1138 trailing spaces in the bounding box as the other drivers did, it also
1139 produced strange results for empty strings or strings containing only
1140 spaces
1141
1142 - when reading CMYK jpeg images they were being transferred to the
1143 image object as is, producing a four channel image. It only looked ok
1144 due to an old still unfixed Photoshop bug. We now convert from the
1145 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1146 http://rt.cpan.org/Ticket/Display.html?id=20416
1147
1148 - reading a CYMK TIFF would result in a 4 channel image, reading any
1149 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1150 result in an error.
1151 http://rt.cpan.org/Ticket/Display.html?id=20415
1152
1153 - added /usr/local/include to the default include search path, since
1154 we were already searching /usr/local/lib for libraries.
1155
1156And various minor fixes and documentation updates.
1157
1158
1159Imager 0.51 - 23 Apr 2006

1163 a crash
1164 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1165
1166 - fix mis-processing of the src_maxx and src_maxy parameters of the
1167 paste() method
1168 http://rt.cpan.org/Public/Bug/Display.html?id=18712

1179 or 4 channel image to jpeg or a 2 channel image to tga where the
1180 output is an in-memeory buffer.
1181 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1182
1183 - fixes an incorrect pointer parameter in the PNG code
1184 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1185
1186 - skip Inline::C tests when building in a directory with spaces
1187 http://rt.cpan.org/Public/Bug/Display.html?id=18049
