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

56
7540f84a
TC
57 - eliminate calls to note(), which isn't in the (very old) version of
58 Test::More we have as a pre-requisite. note() is modern enough
59 that I don't feel a need to require a Test::More upgrade for it.

72 downgrade the version in this file.
73 https://rt.cpan.org/Ticket/Display.html?id=66250
74
75 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
76 that option for the directories that would normally go in
77 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

242
173c91ba 243 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
244 used for color translation on Unix-like systems, and the fix
245 improves performance of supplying colors by name by about 80 times.
246 Test code that managed 3400 10x10 pixel boxes/second sped up to
247 25700 boxes/second.

419Bug fixes:

421 - the conv filter now enforces that the sum of the coefficients is
422 non-zero. Also, rather than skipping pixels off the edge off the
423 edge of the image, the closest edge pixel is used. Previously
424 dividing by the zero sum of coefficients could cause invalid
425 results or runtime exceptions.

427 this bug.

441 - an integer division meant that preview scaling to below 1 pixel
442 wide or high (which isn't too useful anyway) was calculating using
443 NaNs on most platforms, and causing an exception on others.
444 Thanks to David Cantrell for producing a backtrace of the crash on

612This release primarily contains changes to improve ease of use -
613rather than you having to convert images to the appropriate number of
614channels, Imager handles it internally. How to handle drawing colors
615and the default combine mode is a thornier problem left for some other
616release.

TC
621 - moved the imtoc.perl code into Imager::Preprocess
622
623 - paste() and rubthrough() now adapt the source image data to the
624 destination, so you can now safely paste/rubthrough from greyscale
625 images to color images or back, or from alpha channel images to
626 noalpha channels or back.
627 https://rt.cpan.org/Ticket/Display.html?id=30908
628
629 - rubthrough() now falls back to pasting when the source doesn't have
630 an alpha channel. This effectively treats the source as having a
631 max alpha channel, the right thing to do.
632 http://rt.cpan.org/Ticket/Display.html?id=29944
633
634 - re-worked most of the area filling code to use a common set of
635 functions when filling.
636 Corrected normal combine mode.
637 Rewrote most of the combine modes to match the way the SVG draft
638 defines them with respect to a translucent source and destination.
639 Added tests for translucent source and destination.
640 Added tests to check 8-bit/sample and double/sample combines work
641 similarly.

677 - some TGA images weren't being detected correctly as TGA images
678 https://rt.cpan.org/Ticket/Display.html?id=32925
679
680 - handling of the left-over bit for 16-bit/pixel TGA images has been
681 changed to match the behaviour of the GIMP. Previously the bit
682 being set was treated as an opaque pixel, but one user reported a
683 problem with loading such an image. I haven't been able to find any
684 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
685 I'll match it's behaviour. See issue 114913 in the GIMP's
686 bugzilla.

696 - the old dynaload code used Mach API functions to load dynamic
697 libraries on Mac OS X. These APIs have been deprecated in OS X
698 10.5 and were causing some build problems.
699 So henceforth Imager uses the dlopen() family of functions, and you
700 will need version 10.3 or later of OS X.

1004Imager 0.55 - 16 Dec 2006
1005===========
1006
1007This is primarily a bug fix release.
1008
1009Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1010
1011There is one new feature:
1012
1013 - the Win32 font driver now supports UTF8 (RT 22166)
1014 http://www.cpanforum.com/threads/3276
1015 http://rt.cpan.org/Ticket/Display.html?id=22166
1016
1017Several bugs were fixed:
1018
1019 - the string() method would not output the string "0"
1020 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1021
1022 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1023 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1024
1025 - the gif_disposal and gif_user_input tags weren't being read from
1026 the file correctly
1027 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1028
1029 - gif.c was failing to build under MSVC
1030 http://rt.cpan.org/Ticket/Display.html?id=23922
1031
1032 - in some cases strings passed to the string() method were treated as
1033 terminated by NUL (chr 0)
1034 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1035
1036 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1037 that's the default build name for zlib on Win32.
1038 http://rt.cpan.org/Ticket/Display.html?id=23064
1039
1040 - search $Config{incpath} for headers too, which we should have been
1041 doing all along.
1042
1043Win32 font driver fixes:
1044
1045 - the global descent value from bounding box was the wrong sign
1046 http://www.cpanforum.com/threads/3276
1047
1048 - if the first or last glyph overflowed the left or right side of the
1049 advance width they would be clipped
1050
1051
1052Imager 0.54 - 14 Sep 2006
1053===========
1054
1055This is primarily a feature release:
1056
1057 - a new qtype value 'mixing' has been added to the scale()
1058 method. This is faster than 'normal', slower than 'preview'. This
1059 is based on the method used by pnmscale, and seems to produce less
1060 blurry results than normal.
1061 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1062
1063 - the rubthrough() method can now render onto images with an alpha
1064 channel.
1065 http://rt.cpan.org/Ticket/Display.html?id=20678
1066
1067 - the read_multi() method now falls back to calling doing a single
1068 image read via the read() method and write_multi() will now fall
1069 back to calling write() if a single image is supplied. This means
1070 you can simply call the read_multi() or write_multi() functions
1071 without having to check if the type is formatted by that method.
1072 http://rt.cpan.org/Ticket/Display.html?id=19457
1073 http://rt.cpan.org/Ticket/Display.html?id=19458
1074
1075 - the GIF loop extension can now be written. If you don't have
1076 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1077 should upgrade.
1078 http://rt.cpan.org/Ticket/Display.html?id=21185
1079
1080 - getscanline() and setscanline() can now read/write palette index
1081 based data from/to the image for paletted images, by setting type to
1082 'index'.
1083 http://rt.cpan.org/Ticket/Display.html?id=20338
1084
1085 - we no longer hassle you to disable GIF support
1086 http://rt.cpan.org/Ticket/Display.html?id=20687
1087
1088 - minor documentation fixes
1089
1090
1091Imager 0.53 - 26 Jul 2006
1092===========
1093
1094This is a bugfix release.
1095
1096Some test code was left in a code path not covered by the test
1097suite. A test was added to cover this code path and the test code was
1098removed.
1099http://rt.cpan.org/Public/Bug/Display.html?id=20705
1100
1101
1102Imager 0.52 - 25 Jul 2006
1103===========
1104
1105This is primarily a feature release, but contains a fair few bug
1106fixes, new features:
1107
1108 - ability to read and write MS Windows ICO and CUR files
1109
1110 - you can now add file format plugins to support new file formats
1111
1112 - add POD coverage tests
1113
1114 - setcolors() and addcolors() now accept color names and so on
1115 instead of requiring Imager::Color objects.
1116 http://rt.cpan.org/Ticket/Display.html?id=20056
1117
1118 - flood_fill() can now fill to a specified border color instead of
1119 just to the area the same color as the seed.
1120 http://rt.cpan.org/Ticket/Display.html?id=19618
1121
1122
1123Bug fixes:
1124
1125 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1126 calculating the advance width.
1127 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1128
1129 - bounding_box for the T1 driver wasn't including leading and
1130 trailing spaces in the bounding box as the other drivers did, it also
1131 produced strange results for empty strings or strings containing only
1132 spaces
1133
1134 - when reading CMYK jpeg images they were being transferred to the
1135 image object as is, producing a four channel image. It only looked ok
1136 due to an old still unfixed Photoshop bug. We now convert from the
1137 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1138 http://rt.cpan.org/Ticket/Display.html?id=20416
1139
1140 - reading a CYMK TIFF would result in a 4 channel image, reading any
1141 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1142 result in an error.
1143 http://rt.cpan.org/Ticket/Display.html?id=20415
1144
1145 - added /usr/local/include to the default include search path, since
1146 we were already searching /usr/local/lib for libraries.
1147
1148And various minor fixes and documentation updates.
1149
1150

1172 output is an in-memeory buffer.

1174
1175 - fixes an incorrect pointer parameter in the PNG code
1176 http://rt.cpan.org/Public/Bug/Display.html?id=18051

1179 http://rt.cpan.org/Public/Bug/Display.html?id=18049
