6Bug fixes:
7
8 - eliminate calls to i_has_format() from the test suite, since it's
9 no longer a useful way to check for file format support. Eliminate
10 i_has_format() from the functions exposed via XS.

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

27 - increase the version of Imager::Font::Type1 so that upgrades don't
28 downgrade the version in this file.
29 https://rt.cpan.org/Ticket/Display.html?id=66250
30
31 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
32 that option for the directories that would normally go in
33 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

198
173c91ba 199 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
200 used for color translation on Unix-like systems, and the fix
201 improves performance of supplying colors by name by about 80 times.
202 Test code that managed 3400 10x10 pixel boxes/second sped up to
203 25700 boxes/second.

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

375Bug fixes:
376
377 - the conv filter now enforces that the sum of the coefficients is
378 non-zero. Also, rather than skipping pixels off the edge off the
379 edge of the image, the closest edge pixel is used. Previously
380 dividing by the zero sum of coefficients could cause invalid
381 results or runtime exceptions.
382 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
383 this bug.

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

568This release primarily contains changes to improve ease of use -
569rather than you having to convert images to the appropriate number of
570channels, Imager handles it internally. How to handle drawing colors
571and the default combine mode is a thornier problem left for some other
572release.

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

579 - paste() and rubthrough() now adapt the source image data to the
580 destination, so you can now safely paste/rubthrough from greyscale
581 images to color images or back, or from alpha channel images to
582 noalpha channels or back.
583 https://rt.cpan.org/Ticket/Display.html?id=30908
584
585 - rubthrough() now falls back to pasting when the source doesn't have
586 an alpha channel. This effectively treats the source as having a
587 max alpha channel, the right thing to do.
588 http://rt.cpan.org/Ticket/Display.html?id=29944
589
590 - re-worked most of the area filling code to use a common set of
591 functions when filling.
592 Corrected normal combine mode.
593 Rewrote most of the combine modes to match the way the SVG draft
594 defines them with respect to a translucent source and destination.
595 Added tests for translucent source and destination.
596 Added tests to check 8-bit/sample and double/sample combines work
597 similarly.

635
636 - handling of the left-over bit for 16-bit/pixel TGA images has been
637 changed to match the behaviour of the GIMP. Previously the bit
638 being set was treated as an opaque pixel, but one user reported a
639 problem with loading such an image. I haven't been able to find any
640 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
641 I'll match it's behaviour. See issue 114913 in the GIMP's
642 bugzilla.

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

928Bug fixes:
929
930 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)

960Imager 0.55 - 16 Dec 2006
961===========
962
963This is primarily a bug fix release.
964
965Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
966
967There is one new feature:
968
969 - the Win32 font driver now supports UTF8 (RT 22166)
970 http://www.cpanforum.com/threads/3276
971 http://rt.cpan.org/Ticket/Display.html?id=22166
972
973Several bugs were fixed:
974
975 - the string() method would not output the string "0"
976 http://rt.cpan.org/Public/Bug/Display.html?id=21770
977
978 - fills.c was failing to compile on Solaris 10 (compiler unknown)
979 http://rt.cpan.org/Public/Bug/Display.html?id=21944
980
981 - the gif_disposal and gif_user_input tags weren't being read from
982 the file correctly
983 http://rt.cpan.org/Public/Bug/Display.html?id=22192
984
985 - gif.c was failing to build under MSVC
986 http://rt.cpan.org/Ticket/Display.html?id=23922
987
988 - in some cases strings passed to the string() method were treated as
989 terminated by NUL (chr 0)
990 http://rt.cpan.org/Public/Bug/Display.html?id=21770
991
992 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
993 that's the default build name for zlib on Win32.
994 http://rt.cpan.org/Ticket/Display.html?id=23064
995
996 - search $Config{incpath} for headers too, which we should have been
997 doing all along.
998
999Win32 font driver fixes:
1000
1001 - the global descent value from bounding box was the wrong sign
1002 http://www.cpanforum.com/threads/3276
1003
1004 - if the first or last glyph overflowed the left or right side of the
1005 advance width they would be clipped
1006
1007
1008Imager 0.54 - 14 Sep 2006
1009===========
1010
1011This is primarily a feature release:
1012
1013 - a new qtype value 'mixing' has been added to the scale()
1014 method. This is faster than 'normal', slower than 'preview'. This
1015 is based on the method used by pnmscale, and seems to produce less
1016 blurry results than normal.
1017 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1018
1019 - the rubthrough() method can now render onto images with an alpha
1020 channel.
1021 http://rt.cpan.org/Ticket/Display.html?id=20678
1022
1023 - the read_multi() method now falls back to calling doing a single
1024 image read via the read() method and write_multi() will now fall
1025 back to calling write() if a single image is supplied. This means
1026 you can simply call the read_multi() or write_multi() functions
1027 without having to check if the type is formatted by that method.
1028 http://rt.cpan.org/Ticket/Display.html?id=19457
1029 http://rt.cpan.org/Ticket/Display.html?id=19458
1030
1031 - the GIF loop extension can now be written. If you don't have
1032 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1033 should upgrade.
1034 http://rt.cpan.org/Ticket/Display.html?id=21185
1035
1036 - getscanline() and setscanline() can now read/write palette index
1037 based data from/to the image for paletted images, by setting type to
1038 'index'.
1039 http://rt.cpan.org/Ticket/Display.html?id=20338
1040
1041 - we no longer hassle you to disable GIF support
1042 http://rt.cpan.org/Ticket/Display.html?id=20687
1043
1044 - minor documentation fixes
1045
1046
1047Imager 0.53 - 26 Jul 2006
1048===========
1049
1050This is a bugfix release.
1051
1052Some test code was left in a code path not covered by the test
1053suite. A test was added to cover this code path and the test code was
1054removed.
1055http://rt.cpan.org/Public/Bug/Display.html?id=20705
1056
1057
1058Imager 0.52 - 25 Jul 2006
1059===========
1060
1061This is primarily a feature release, but contains a fair few bug
1062fixes, new features:
1063
1064 - ability to read and write MS Windows ICO and CUR files
1065
1066 - you can now add file format plugins to support new file formats
1067
1068 - add POD coverage tests
1069
1070 - setcolors() and addcolors() now accept color names and so on
1071 instead of requiring Imager::Color objects.
1072 http://rt.cpan.org/Ticket/Display.html?id=20056
1073
1074 - flood_fill() can now fill to a specified border color instead of
1075 just to the area the same color as the seed.
1076 http://rt.cpan.org/Ticket/Display.html?id=19618
1077
1078
1079Bug fixes:
1080
1081 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1082 calculating the advance width.
1083 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1084
1085 - bounding_box for the T1 driver wasn't including leading and
1086 trailing spaces in the bounding box as the other drivers did, it also
1087 produced strange results for empty strings or strings containing only
1088 spaces
1089
1090 - when reading CMYK jpeg images they were being transferred to the
1091 image object as is, producing a four channel image. It only looked ok
1092 due to an old still unfixed Photoshop bug. We now convert from the
1093 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1094 http://rt.cpan.org/Ticket/Display.html?id=20416
1095
1096 - reading a CYMK TIFF would result in a 4 channel image, reading any
1097 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1098 result in an error.
1099 http://rt.cpan.org/Ticket/Display.html?id=20415
1100
1101 - added /usr/local/include to the default include search path, since
1102 we were already searching /usr/local/lib for libraries.
1103
1104And various minor fixes and documentation updates.
1105
1106
1107Imager 0.51 - 23 Apr 2006

1111 a crash
1112 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1113
1114 - fix mis-processing of the src_maxx and src_maxy parameters of the
1115 paste() method
1116 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1117
1118 - fix a problem in Imager's "smart" handling of the color parameter
1119 to various methods.
1120 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1121
1122

1124===========
1125

1127 or 4 channel image to jpeg or a 2 channel image to tga where the
1128 output is an in-memeory buffer.
1129 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1130
1131 - fixes an incorrect pointer parameter in the PNG code
1132 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1133
1134 - skip Inline::C tests when building in a directory with spaces
