TC
13===========
14
15Bug fixes:
16
17 - eliminate calls to i_has_format() from the test suite, since it's
18 no longer a useful way to check for file format support. Eliminate
19 i_has_format() from the functions exposed via XS.
20 https://rt.cpan.org/Ticket/Display.html?id=65863
21
7540f84a
TC
22 - eliminate calls to note(), which isn't in the (very old) version of
23 Test::More we have as a pre-requisite. note() is modern enough
24 that I don't feel a need to require a Test::More upgrade for it.
25 https://rt.cpan.org/Ticket/Display.html?id=65864

TC
36 - increase the version of Imager::Font::Type1 so that upgrades don't
37 downgrade the version in this file.
38 https://rt.cpan.org/Ticket/Display.html?id=66250
39
40 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
41 that option for the directories that would normally go in
42 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

207
173c91ba 208 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
209 used for color translation on Unix-like systems, and the fix
210 improves performance of supplying colors by name by about 80 times.
211 Test code that managed 3400 10x10 pixel boxes/second sped up to
212 25700 boxes/second.

265 - added the ability to read multiple-image PNM files.
266 Note that unlike the pbm/pgm/ppm specification this accepts mixed

373 - prevent double-frees when someone creates Imager objects and then

384Bug fixes:
385
386 - the conv filter now enforces that the sum of the coefficients is
387 non-zero. Also, rather than skipping pixels off the edge off the
388 edge of the image, the closest edge pixel is used. Previously
389 dividing by the zero sum of coefficients could cause invalid
390 results or runtime exceptions.
391 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
392 this bug.

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

577This release primarily contains changes to improve ease of use -
578rather than you having to convert images to the appropriate number of
579channels, Imager handles it internally. How to handle drawing colors
580and the default combine mode is a thornier problem left for some other
581release.

TC
586 - moved the imtoc.perl code into Imager::Preprocess
587
588 - paste() and rubthrough() now adapt the source image data to the
589 destination, so you can now safely paste/rubthrough from greyscale
590 images to color images or back, or from alpha channel images to
591 noalpha channels or back.
592 https://rt.cpan.org/Ticket/Display.html?id=30908
593
594 - rubthrough() now falls back to pasting when the source doesn't have
595 an alpha channel. This effectively treats the source as having a
596 max alpha channel, the right thing to do.
597 http://rt.cpan.org/Ticket/Display.html?id=29944
598
599 - re-worked most of the area filling code to use a common set of
600 functions when filling.
601 Corrected normal combine mode.
602 Rewrote most of the combine modes to match the way the SVG draft
603 defines them with respect to a translucent source and destination.
604 Added tests for translucent source and destination.
605 Added tests to check 8-bit/sample and double/sample combines work
606 similarly.

644
645 - handling of the left-over bit for 16-bit/pixel TGA images has been
646 changed to match the behaviour of the GIMP. Previously the bit
647 being set was treated as an opaque pixel, but one user reported a
648 problem with loading such an image. I haven't been able to find any
649 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
650 I'll match it's behaviour. See issue 114913 in the GIMP's
651 bugzilla.

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

969Imager 0.55 - 16 Dec 2006
970===========
971
972This is primarily a bug fix release.
973
974Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
975
976There is one new feature:
977
978 - the Win32 font driver now supports UTF8 (RT 22166)
979 http://www.cpanforum.com/threads/3276
980 http://rt.cpan.org/Ticket/Display.html?id=22166
981
982Several bugs were fixed:
983
984 - the string() method would not output the string "0"
985 http://rt.cpan.org/Public/Bug/Display.html?id=21770
986
987 - fills.c was failing to compile on Solaris 10 (compiler unknown)
988 http://rt.cpan.org/Public/Bug/Display.html?id=21944
989
990 - the gif_disposal and gif_user_input tags weren't being read from
991 the file correctly
992 http://rt.cpan.org/Public/Bug/Display.html?id=22192
993
994 - gif.c was failing to build under MSVC
995 http://rt.cpan.org/Ticket/Display.html?id=23922
996
997 - in some cases strings passed to the string() method were treated as
998 terminated by NUL (chr 0)
999 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1000
1001 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1002 that's the default build name for zlib on Win32.
1003 http://rt.cpan.org/Ticket/Display.html?id=23064
1004
1005 - search $Config{incpath} for headers too, which we should have been
1006 doing all along.
1007
1008Win32 font driver fixes:
1009
1010 - the global descent value from bounding box was the wrong sign
1011 http://www.cpanforum.com/threads/3276
1012
1013 - if the first or last glyph overflowed the left or right side of the
1014 advance width they would be clipped
1015
1016
1017Imager 0.54 - 14 Sep 2006
1018===========
1019
1020This is primarily a feature release:
1021
1022 - a new qtype value 'mixing' has been added to the scale()
1023 method. This is faster than 'normal', slower than 'preview'. This
1024 is based on the method used by pnmscale, and seems to produce less
1025 blurry results than normal.
1026 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1027
1028 - the rubthrough() method can now render onto images with an alpha
1029 channel.
1030 http://rt.cpan.org/Ticket/Display.html?id=20678
1031
1032 - the read_multi() method now falls back to calling doing a single
1033 image read via the read() method and write_multi() will now fall
1034 back to calling write() if a single image is supplied. This means
1035 you can simply call the read_multi() or write_multi() functions
1036 without having to check if the type is formatted by that method.
1037 http://rt.cpan.org/Ticket/Display.html?id=19457
1038 http://rt.cpan.org/Ticket/Display.html?id=19458
1039
1040 - the GIF loop extension can now be written. If you don't have
1041 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1042 should upgrade.
1043 http://rt.cpan.org/Ticket/Display.html?id=21185
1044
1045 - getscanline() and setscanline() can now read/write palette index
1046 based data from/to the image for paletted images, by setting type to
1047 'index'.
1048 http://rt.cpan.org/Ticket/Display.html?id=20338
1049
1050 - we no longer hassle you to disable GIF support
1051 http://rt.cpan.org/Ticket/Display.html?id=20687
1052
1053 - minor documentation fixes
1054
1055
1056Imager 0.53 - 26 Jul 2006
1057===========
1058
1059This is a bugfix release.
1060
1061Some test code was left in a code path not covered by the test
1062suite. A test was added to cover this code path and the test code was
1063removed.
1064http://rt.cpan.org/Public/Bug/Display.html?id=20705
1065
1066
1067Imager 0.52 - 25 Jul 2006
1068===========
1069
1070This is primarily a feature release, but contains a fair few bug
1071fixes, new features:
1072
1073 - ability to read and write MS Windows ICO and CUR files
1074
1075 - you can now add file format plugins to support new file formats
1076
1077 - add POD coverage tests
1078
1079 - setcolors() and addcolors() now accept color names and so on
1080 instead of requiring Imager::Color objects.
1081 http://rt.cpan.org/Ticket/Display.html?id=20056
1082
1083 - flood_fill() can now fill to a specified border color instead of
1084 just to the area the same color as the seed.
1085 http://rt.cpan.org/Ticket/Display.html?id=19618
1086
1087
1088Bug fixes:
1089
1090 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1091 calculating the advance width.
1092 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1093
1094 - bounding_box for the T1 driver wasn't including leading and
1095 trailing spaces in the bounding box as the other drivers did, it also
1096 produced strange results for empty strings or strings containing only
1097 spaces
1098
1099 - when reading CMYK jpeg images they were being transferred to the
1100 image object as is, producing a four channel image. It only looked ok
1101 due to an old still unfixed Photoshop bug. We now convert from the
1102 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1103 http://rt.cpan.org/Ticket/Display.html?id=20416
1104
1105 - reading a CYMK TIFF would result in a 4 channel image, reading any
1106 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1107 result in an error.
1108 http://rt.cpan.org/Ticket/Display.html?id=20415
1109
1110 - added /usr/local/include to the default include search path, since
1111 we were already searching /usr/local/lib for libraries.
1112
1113And various minor fixes and documentation updates.
1114
1115
1116Imager 0.51 - 23 Apr 2006

1120 a crash
1121 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1122
1123 - fix mis-processing of the src_maxx and src_maxy parameters of the
1124 paste() method
1125 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1126
1127 - fix a problem in Imager's "smart" handling of the color parameter
1128 to various methods.

1136 or 4 channel image to jpeg or a 2 channel image to tga where the
1137 output is an in-memeory buffer.
1138 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1139
1140 - fixes an incorrect pointer parameter in the PNG code
1141 http://rt.cpan.org/Public/Bug/Display.html?id=18051
