50===========
51
52Bug fixes:
53
54 - eliminate calls to i_has_format() from the test suite, since it's
55 no longer a useful way to check for file format support. Eliminate
56 i_has_format() from the functions exposed via XS.

58
7540f84a
TC
59 - eliminate calls to note(), which isn't in the (very old) version of
60 Test::More we have as a pre-requisite. note() is modern enough
61 that I don't feel a need to require a Test::More upgrade for it.
62 https://rt.cpan.org/Ticket/Display.html?id=65864

73 - increase the version of Imager::Font::Type1 so that upgrades don't
74 downgrade the version in this file.
75 https://rt.cpan.org/Ticket/Display.html?id=66250
76
77 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
78 that option for the directories that would normally go in
79 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

244
173c91ba 245 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
246 used for color translation on Unix-like systems, and the fix
247 improves performance of supplying colors by name by about 80 times.
248 Test code that managed 3400 10x10 pixel boxes/second sped up to
249 25700 boxes/second.

410 - prevent double-frees when someone creates Imager objects and then
411 creates a thread. Note: this just handles some simple cases,

421Bug fixes:
422
423 - the conv filter now enforces that the sum of the coefficients is
424 non-zero. Also, rather than skipping pixels off the edge off the
425 edge of the image, the closest edge pixel is used. Previously
426 dividing by the zero sum of coefficients could cause invalid
427 results or runtime exceptions.
428 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
429 this bug.

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

614This release primarily contains changes to improve ease of use -

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

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

627 images to color images or back, or from alpha channel images to
628 noalpha channels or back.
629 https://rt.cpan.org/Ticket/Display.html?id=30908
630
631 - rubthrough() now falls back to pasting when the source doesn't have
632 an alpha channel. This effectively treats the source as having a
633 max alpha channel, the right thing to do.
634 http://rt.cpan.org/Ticket/Display.html?id=29944
635
636 - re-worked most of the area filling code to use a common set of
637 functions when filling.

639 Rewrote most of the combine modes to match the way the SVG draft
640 defines them with respect to a translucent source and destination.

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

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

1006Imager 0.55 - 16 Dec 2006
1007===========
1008
1009This is primarily a bug fix release.
1010
1011Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1012
1013There is one new feature:
1014
1015 - the Win32 font driver now supports UTF8 (RT 22166)
1016 http://www.cpanforum.com/threads/3276
1017 http://rt.cpan.org/Ticket/Display.html?id=22166
1018
1019Several bugs were fixed:
1020
1021 - the string() method would not output the string "0"
1022 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1023
1024 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1025 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1026
1027 - the gif_disposal and gif_user_input tags weren't being read from
1028 the file correctly
1029 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1030
1031 - gif.c was failing to build under MSVC
1032 http://rt.cpan.org/Ticket/Display.html?id=23922
1033
1034 - in some cases strings passed to the string() method were treated as
1035 terminated by NUL (chr 0)
1036 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1037
1038 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1039 that's the default build name for zlib on Win32.
1040 http://rt.cpan.org/Ticket/Display.html?id=23064
1041
1042 - search $Config{incpath} for headers too, which we should have been
1043 doing all along.
1044
1045Win32 font driver fixes:
1046
1047 - the global descent value from bounding box was the wrong sign
1048 http://www.cpanforum.com/threads/3276
1049
1050 - if the first or last glyph overflowed the left or right side of the
1051 advance width they would be clipped
1052
1053
1054Imager 0.54 - 14 Sep 2006
1055===========
1056
1057This is primarily a feature release:
1058
1059 - a new qtype value 'mixing' has been added to the scale()
1060 method. This is faster than 'normal', slower than 'preview'. This
1061 is based on the method used by pnmscale, and seems to produce less
1062 blurry results than normal.
1063 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1064
1065 - the rubthrough() method can now render onto images with an alpha
1066 channel.
1067 http://rt.cpan.org/Ticket/Display.html?id=20678
1068
1069 - the read_multi() method now falls back to calling doing a single
1070 image read via the read() method and write_multi() will now fall
1071 back to calling write() if a single image is supplied. This means
1072 you can simply call the read_multi() or write_multi() functions
1073 without having to check if the type is formatted by that method.
1074 http://rt.cpan.org/Ticket/Display.html?id=19457
1075 http://rt.cpan.org/Ticket/Display.html?id=19458
1076
1077 - the GIF loop extension can now be written. If you don't have
1078 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1079 should upgrade.
1080 http://rt.cpan.org/Ticket/Display.html?id=21185
1081
1082 - getscanline() and setscanline() can now read/write palette index
1083 based data from/to the image for paletted images, by setting type to
1084 'index'.
1085 http://rt.cpan.org/Ticket/Display.html?id=20338
1086
1087 - we no longer hassle you to disable GIF support
1088 http://rt.cpan.org/Ticket/Display.html?id=20687
1089
1090 - minor documentation fixes
1091
1092
1093Imager 0.53 - 26 Jul 2006
1094===========
1095
1096This is a bugfix release.
1097
1098Some test code was left in a code path not covered by the test
1099suite. A test was added to cover this code path and the test code was
1100removed.
1101http://rt.cpan.org/Public/Bug/Display.html?id=20705
1102
1103
1104Imager 0.52 - 25 Jul 2006
1105===========
1106
1107This is primarily a feature release, but contains a fair few bug
1108fixes, new features:
1109
1110 - ability to read and write MS Windows ICO and CUR files
1111
1112 - you can now add file format plugins to support new file formats
1113
1114 - add POD coverage tests
1115
1116 - setcolors() and addcolors() now accept color names and so on
1117 instead of requiring Imager::Color objects.
1118 http://rt.cpan.org/Ticket/Display.html?id=20056
1119
1120 - flood_fill() can now fill to a specified border color instead of
1121 just to the area the same color as the seed.
1122 http://rt.cpan.org/Ticket/Display.html?id=19618
1123
1124
1125Bug fixes:
1126
1127 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1128 calculating the advance width.
1129 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1130
1131 - bounding_box for the T1 driver wasn't including leading and
1132 trailing spaces in the bounding box as the other drivers did, it also
1133 produced strange results for empty strings or strings containing only
1134 spaces
1135
1136 - when reading CMYK jpeg images they were being transferred to the
1137 image object as is, producing a four channel image. It only looked ok
1138 due to an old still unfixed Photoshop bug. We now convert from the
1139 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1140 http://rt.cpan.org/Ticket/Display.html?id=20416
1141
1142 - reading a CYMK TIFF would result in a 4 channel image, reading any
1143 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1144 result in an error.
1145 http://rt.cpan.org/Ticket/Display.html?id=20415
1146
1147 - added /usr/local/include to the default include search path, since
1148 we were already searching /usr/local/lib for libraries.
1149
1150And various minor fixes and documentation updates.
1151
1152
1153Imager 0.51 - 23 Apr 2006

1158 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1159
1160 - fix mis-processing of the src_maxx and src_maxy parameters of the
1161 paste() method
1162 http://rt.cpan.org/Public/Bug/Display.html?id=18712

1174 output is an in-memeory buffer.
1175 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1176
1177 - fixes an incorrect pointer parameter in the PNG code
1178 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1179
1180 - skip Inline::C tests when building in a directory with spaces
1181 http://rt.cpan.org/Public/Bug/Display.html?id=18049
