4===========

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.

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.

189
173c91ba 190 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
191 used for color translation on Unix-like systems, and the fix
192 improves performance of supplying colors by name by about 80 times.
193 Test code that managed 3400 10x10 pixel boxes/second sped up to
194 25700 boxes/second.

TC
247 - added the ability to read multiple-image PNM files.
248 Note that unlike the pbm/pgm/ppm specification this accepts mixed
249 format files and allows white space padding between files.

251
1d7e3124
TC

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

TC
366Bug fixes:
367
368 - the conv filter now enforces that the sum of the coefficients is
369 non-zero. Also, rather than skipping pixels off the edge off the
370 edge of the image, the closest edge pixel is used. Previously
371 dividing by the zero sum of coefficients could cause invalid
372 results or runtime exceptions.
373 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
374 this bug.

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

559This release primarily contains changes to improve ease of use -
560rather than you having to convert images to the appropriate number of
561channels, Imager handles it internally. How to handle drawing colors
562and the default combine mode is a thornier problem left for some other
563release.

TC
568 - moved the imtoc.perl code into Imager::Preprocess
569
570 - paste() and rubthrough() now adapt the source image data to the
571 destination, so you can now safely paste/rubthrough from greyscale
572 images to color images or back, or from alpha channel images to
573 noalpha channels or back.
574 https://rt.cpan.org/Ticket/Display.html?id=30908
575
576 - rubthrough() now falls back to pasting when the source doesn't have
577 an alpha channel. This effectively treats the source as having a
578 max alpha channel, the right thing to do.
579 http://rt.cpan.org/Ticket/Display.html?id=29944
580
581 - re-worked most of the area filling code to use a common set of
582 functions when filling.
583 Corrected normal combine mode.
584 Rewrote most of the combine modes to match the way the SVG draft
585 defines them with respect to a translucent source and destination.
586 Added tests for translucent source and destination.
587 Added tests to check 8-bit/sample and double/sample combines work
588 similarly.

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

919Bug fixes:
920
921 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)

951Imager 0.55 - 16 Dec 2006
952===========
953
954This is primarily a bug fix release.
955
956Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
957
958There is one new feature:
959
960 - the Win32 font driver now supports UTF8 (RT 22166)
961 http://www.cpanforum.com/threads/3276
962 http://rt.cpan.org/Ticket/Display.html?id=22166
963
964Several bugs were fixed:
965
966 - the string() method would not output the string "0"
967 http://rt.cpan.org/Public/Bug/Display.html?id=21770
968
969 - fills.c was failing to compile on Solaris 10 (compiler unknown)
970 http://rt.cpan.org/Public/Bug/Display.html?id=21944
971
972 - the gif_disposal and gif_user_input tags weren't being read from
973 the file correctly
974 http://rt.cpan.org/Public/Bug/Display.html?id=22192
975
976 - gif.c was failing to build under MSVC
977 http://rt.cpan.org/Ticket/Display.html?id=23922
978
979 - in some cases strings passed to the string() method were treated as
980 terminated by NUL (chr 0)
981 http://rt.cpan.org/Public/Bug/Display.html?id=21770
982
983 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
984 that's the default build name for zlib on Win32.
985 http://rt.cpan.org/Ticket/Display.html?id=23064
986
987 - search $Config{incpath} for headers too, which we should have been
988 doing all along.
989
990Win32 font driver fixes:
991
992 - the global descent value from bounding box was the wrong sign
993 http://www.cpanforum.com/threads/3276
994
995 - if the first or last glyph overflowed the left or right side of the
996 advance width they would be clipped
997
998
999Imager 0.54 - 14 Sep 2006
1000===========
1001
1002This is primarily a feature release:
1003
1004 - a new qtype value 'mixing' has been added to the scale()
1005 method. This is faster than 'normal', slower than 'preview'. This
1006 is based on the method used by pnmscale, and seems to produce less
1007 blurry results than normal.
1008 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1009
1010 - the rubthrough() method can now render onto images with an alpha
1011 channel.
1012 http://rt.cpan.org/Ticket/Display.html?id=20678
1013
1014 - the read_multi() method now falls back to calling doing a single
1015 image read via the read() method and write_multi() will now fall
1016 back to calling write() if a single image is supplied. This means
1017 you can simply call the read_multi() or write_multi() functions
1018 without having to check if the type is formatted by that method.
1019 http://rt.cpan.org/Ticket/Display.html?id=19457
1020 http://rt.cpan.org/Ticket/Display.html?id=19458
1021
1022 - the GIF loop extension can now be written. If you don't have
1023 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1024 should upgrade.
1025 http://rt.cpan.org/Ticket/Display.html?id=21185
1026
1027 - getscanline() and setscanline() can now read/write palette index
1028 based data from/to the image for paletted images, by setting type to
1029 'index'.
1030 http://rt.cpan.org/Ticket/Display.html?id=20338
1031
1032 - we no longer hassle you to disable GIF support
1033 http://rt.cpan.org/Ticket/Display.html?id=20687
1034
1035 - minor documentation fixes
1036
1037
1038Imager 0.53 - 26 Jul 2006
1039===========
1040
1041This is a bugfix release.
1042
1043Some test code was left in a code path not covered by the test
1044suite. A test was added to cover this code path and the test code was
1045removed.
1046http://rt.cpan.org/Public/Bug/Display.html?id=20705
1047
1048
1049Imager 0.52 - 25 Jul 2006
1050===========
1051
1052This is primarily a feature release, but contains a fair few bug
1053fixes, new features:
1054
1055 - ability to read and write MS Windows ICO and CUR files
1056
1057 - you can now add file format plugins to support new file formats
1058
1059 - add POD coverage tests
1060
1061 - setcolors() and addcolors() now accept color names and so on
1062 instead of requiring Imager::Color objects.
1063 http://rt.cpan.org/Ticket/Display.html?id=20056
1064
1065 - flood_fill() can now fill to a specified border color instead of
1066 just to the area the same color as the seed.
1067 http://rt.cpan.org/Ticket/Display.html?id=19618
1068
1069
1070Bug fixes:
1071
1072 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1073 calculating the advance width.
1074 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1075
1076 - bounding_box for the T1 driver wasn't including leading and
1077 trailing spaces in the bounding box as the other drivers did, it also
1078 produced strange results for empty strings or strings containing only
1079 spaces
1080
1081 - when reading CMYK jpeg images they were being transferred to the
1082 image object as is, producing a four channel image. It only looked ok
1083 due to an old still unfixed Photoshop bug. We now convert from the
1084 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1085 http://rt.cpan.org/Ticket/Display.html?id=20416
1086
1087 - reading a CYMK TIFF would result in a 4 channel image, reading any
1088 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1089 result in an error.
1090 http://rt.cpan.org/Ticket/Display.html?id=20415
1091
1092 - added /usr/local/include to the default include search path, since
1093 we were already searching /usr/local/lib for libraries.
1094
1095And various minor fixes and documentation updates.
1096
1097
1098Imager 0.51 - 23 Apr 2006

1102 a crash
1103 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1104
1105 - fix mis-processing of the src_maxx and src_maxy parameters of the
1106 paste() method
1107 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1108
1109 - fix a problem in Imager's "smart" handling of the color parameter

1112
1113

1118 or 4 channel image to jpeg or a 2 channel image to tga where the
1119 output is an in-memeory buffer.
1120 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1121
1122 - fixes an incorrect pointer parameter in the PNG code
1123 http://rt.cpan.org/Public/Bug/Display.html?id=18051
