28 - convert colors to grayscale if the supplied (or generated) palette
29 contains only grays when performing error diffusion color
30 translation.
31 https://rt.cpan.org/Ticket/Display.html?id=68508
32
59c150a4
TC
33 - writing a paletted image to GIF wouldn't always use the colors
34 supplied (or generated, eg. via make_colors => "mono"), which was
35 confusing at best.
36 https://rt.cpan.org/Ticket/Display.html?id=67912
37
5b480b14
TC
38 - replace (imager|tony)@imager.perl.org in the doc, since I don't

55
56Bug fixes:

61

62 - compose() with the target, source or mask position off the top or
63 left of the target image didn't clip the source image correctly.
64 https://rt.cpan.org/Ticket/Display.html?id=67220
65
66 - compose() now returns a useful error message on a non-positive
67 opacity.

69 - compose.im now at 100% test coverage. (As opposed to, umm, much,
70 much less.)

TC
73===========
74
75Bug fixes:
76
77 - eliminate calls to i_has_format() from the test suite, since it's
78 no longer a useful way to check for file format support. Eliminate
79 i_has_format() from the functions exposed via XS.
80 https://rt.cpan.org/Ticket/Display.html?id=65863
81
7540f84a
TC
82 - eliminate calls to note(), which isn't in the (very old) version of
83 Test::More we have as a pre-requisite. note() is modern enough
84 that I don't feel a need to require a Test::More upgrade for it.
85 https://rt.cpan.org/Ticket/Display.html?id=65864
86
81984f30

87 - skip the threads tests on Test::More 2.00_*

c901f27d
TC
96 - increase the version of Imager::Font::Type1 so that upgrades don't
97 downgrade the version in this file.
98 https://rt.cpan.org/Ticket/Display.html?id=66250
99
100 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
101 that option for the directories that would normally go in
102 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

173c91ba 268 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
269 used for color translation on Unix-like systems, and the fix

448 edge of the image, the closest edge pixel is used. Previously
449 dividing by the zero sum of coefficients could cause invalid
450 results or runtime exceptions.
451 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
452 this bug.

637This release primarily contains changes to improve ease of use -

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

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

650 images to color images or back, or from alpha channel images to
651 noalpha channels or back.
652 https://rt.cpan.org/Ticket/Display.html?id=30908
653
654 - rubthrough() now falls back to pasting when the source doesn't have
655 an alpha channel. This effectively treats the source as having a
656 max alpha channel, the right thing to do.
657 http://rt.cpan.org/Ticket/Display.html?id=29944
658
659 - re-worked most of the area filling code to use a common set of

663 defines them with respect to a translucent source and destination.

706 changed to match the behaviour of the GIMP. Previously the bit
707 being set was treated as an opaque pixel, but one user reported a
708 problem with loading such an image. I haven't been able to find any
709 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
710 I'll match it's behaviour. See issue 114913 in the GIMP's
711 bugzilla.

1029Imager 0.55 - 16 Dec 2006
1030===========
1031
1032This is primarily a bug fix release.
1033
1034Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1035
1036There is one new feature:
1037
1038 - the Win32 font driver now supports UTF8 (RT 22166)
1039 http://www.cpanforum.com/threads/3276
1040 http://rt.cpan.org/Ticket/Display.html?id=22166
1041
1042Several bugs were fixed:
1043
1044 - the string() method would not output the string "0"
1045 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1046
1047 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1048 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1049
1050 - the gif_disposal and gif_user_input tags weren't being read from
1051 the file correctly
1052 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1053
1054 - gif.c was failing to build under MSVC
1055 http://rt.cpan.org/Ticket/Display.html?id=23922
1056
1057 - in some cases strings passed to the string() method were treated as
1058 terminated by NUL (chr 0)
1059 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1060
1061 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1062 that's the default build name for zlib on Win32.
1063 http://rt.cpan.org/Ticket/Display.html?id=23064
1064
1065 - search $Config{incpath} for headers too, which we should have been
1066 doing all along.
1067
1068Win32 font driver fixes:
1069
1070 - the global descent value from bounding box was the wrong sign
1071 http://www.cpanforum.com/threads/3276
1072
1073 - if the first or last glyph overflowed the left or right side of the
1074 advance width they would be clipped
1075
1076
1077Imager 0.54 - 14 Sep 2006
1078===========
1079
1080This is primarily a feature release:
1081
1082 - a new qtype value 'mixing' has been added to the scale()
1083 method. This is faster than 'normal', slower than 'preview'. This
1084 is based on the method used by pnmscale, and seems to produce less
1085 blurry results than normal.
1086 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1087
1088 - the rubthrough() method can now render onto images with an alpha
1089 channel.
1090 http://rt.cpan.org/Ticket/Display.html?id=20678
1091
1092 - the read_multi() method now falls back to calling doing a single
1093 image read via the read() method and write_multi() will now fall
1094 back to calling write() if a single image is supplied. This means
1095 you can simply call the read_multi() or write_multi() functions
1096 without having to check if the type is formatted by that method.
1097 http://rt.cpan.org/Ticket/Display.html?id=19457
1098 http://rt.cpan.org/Ticket/Display.html?id=19458
1099
1100 - the GIF loop extension can now be written. If you don't have
1101 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1102 should upgrade.
1103 http://rt.cpan.org/Ticket/Display.html?id=21185
1104
1105 - getscanline() and setscanline() can now read/write palette index
1106 based data from/to the image for paletted images, by setting type to
1107 'index'.
1108 http://rt.cpan.org/Ticket/Display.html?id=20338
1109
1110 - we no longer hassle you to disable GIF support
1111 http://rt.cpan.org/Ticket/Display.html?id=20687
1112
1113 - minor documentation fixes
1114
1115
1116Imager 0.53 - 26 Jul 2006
1117===========
1118
1119This is a bugfix release.
1120
1121Some test code was left in a code path not covered by the test
1122suite. A test was added to cover this code path and the test code was
1123removed.

1125
1126
1127Imager 0.52 - 25 Jul 2006
1128===========
1129
1130This is primarily a feature release, but contains a fair few bug
1131fixes, new features:
1132
1133 - ability to read and write MS Windows ICO and CUR files
1134
1135 - you can now add file format plugins to support new file formats
1136
1137 - add POD coverage tests
1138
1139 - setcolors() and addcolors() now accept color names and so on
1140 instead of requiring Imager::Color objects.
1141 http://rt.cpan.org/Ticket/Display.html?id=20056
1142
1143 - flood_fill() can now fill to a specified border color instead of
1144 just to the area the same color as the seed.
1145 http://rt.cpan.org/Ticket/Display.html?id=19618
1146
1147
1148Bug fixes:
1149
1150 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1151 calculating the advance width.
1152 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1153
1154 - bounding_box for the T1 driver wasn't including leading and
1155 trailing spaces in the bounding box as the other drivers did, it also
1156 produced strange results for empty strings or strings containing only
1157 spaces
1158
1159 - when reading CMYK jpeg images they were being transferred to the
1160 image object as is, producing a four channel image. It only looked ok
1161 due to an old still unfixed Photoshop bug. We now convert from the
1162 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1163 http://rt.cpan.org/Ticket/Display.html?id=20416
1164
1165 - reading a CYMK TIFF would result in a 4 channel image, reading any
1166 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1167 result in an error.
1168 http://rt.cpan.org/Ticket/Display.html?id=20415
1169
1170 - added /usr/local/include to the default include search path, since
1171 we were already searching /usr/local/lib for libraries.
1172
1173And various minor fixes and documentation updates.
1174
1175
1176Imager 0.51 - 23 Apr 2006
