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.

173c91ba 184 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
185 used for color translation on Unix-like systems, and the fix
186 improves performance of supplying colors by name by about 80 times.
187 Test code that managed 3400 10x10 pixel boxes/second sped up to
188 25700 boxes/second.

ffddd407
TC
349 - prevent double-frees when someone creates Imager objects and then
350 creates a thread. Note: this just handles some simple cases,
351 Imager doesn't support perl threads, and isn't likely to.

TC
360Bug fixes:
361
362 - the conv filter now enforces that the sum of the coefficients is
363 non-zero. Also, rather than skipping pixels off the edge off the
364 edge of the image, the closest edge pixel is used. Previously
365 dividing by the zero sum of coefficients could cause invalid
366 results or runtime exceptions.
367 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
368 this bug.

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

531 - check that the result of fileno($fh) is defined rather than simply
532 true when read() or write() is supplied with an fh parameter.
533 http://rt.cpan.org/Ticket/Display.html?id=35139
534
535 - i_scale_axis() wasn't checking the result of i_img_new_ch()
536 resulting in a SIGSEGV when attempting to scale an image to a size
537 too large to fit in memory. This is a NULL pointer access issue,
538 not a buffer overflow.
539 Added a check for the failure.
540 scale_calculate() (and hence scale()) will now fail if any of the
541 scale size parameters are a reference.

553This release primarily contains changes to improve ease of use -
554rather than you having to convert images to the appropriate number of
555channels, Imager handles it internally. How to handle drawing colors
556and the default combine mode is a thornier problem left for some other
557release.

TC
562 - moved the imtoc.perl code into Imager::Preprocess
563
564 - paste() and rubthrough() now adapt the source image data to the
565 destination, so you can now safely paste/rubthrough from greyscale
566 images to color images or back, or from alpha channel images to
567 noalpha channels or back.
568 https://rt.cpan.org/Ticket/Display.html?id=30908
569
570 - rubthrough() now falls back to pasting when the source doesn't have
571 an alpha channel. This effectively treats the source as having a
572 max alpha channel, the right thing to do.
573 http://rt.cpan.org/Ticket/Display.html?id=29944
574
575 - re-worked most of the area filling code to use a common set of
576 functions when filling.
577 Corrected normal combine mode.
578 Rewrote most of the combine modes to match the way the SVG draft
579 defines them with respect to a translucent source and destination.
580 Added tests for translucent source and destination.
581 Added tests to check 8-bit/sample and double/sample combines work
582 similarly.

620
621 - handling of the left-over bit for 16-bit/pixel TGA images has been
622 changed to match the behaviour of the GIMP. Previously the bit
623 being set was treated as an opaque pixel, but one user reported a
624 problem with loading such an image. I haven't been able to find any
625 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
626 I'll match it's behaviour. See issue 114913 in the GIMP's
627 bugzilla.

637 - the old dynaload code used Mach API functions to load dynamic
638 libraries on Mac OS X. These APIs have been deprecated in OS X
639 10.5 and were causing some build problems.

641 will need version 10.3 or later of OS X.

913Bug fixes:
914
915 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
916 was returning an image object with an extra reference, this
917 resulted in a memory leak.
918 http://rt.cpan.org/Ticket/Display.html?id=24992
919
920 - fix rendering on alpha channel images for the FreeType 2.x driver
921 http://rt.cpan.org/Ticket/Display.html?id=11972
922
923 - reading bmp files now consitently handles short reads. You can now
924 supply a parameter to treat a short read as successful and set
925 i_incomplete
926 http://rt.cpan.org/Ticket/Display.html?id=8426
927
928 - previously, reading ASCII PBM files required spaces between samples,
929 even though the format doesn't require that
930

TC
931 - improved documentation of the unsharpmask filter (I hope)
932 http://rt.cpan.org/Ticket/Display.html?id=25531
933
934 - force flushing of the output from i_tt_dump_names() and test output
935 in t/t35ttfont.t to prevent output from being mixed up.
936 https://rt.cpan.org/Ticket/Display.html?id=24859
937
938 - rewrite a conditional expression as an if() to hopefully work around
939 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
940 https://rt.cpan.org/Ticket/Display.html?id=25561
941
942 - avoid Data::Dumper in regops.perl to support older releases of perl

945Imager 0.55 - 16 Dec 2006
946===========
947
948This is primarily a bug fix release.
949
950Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
951
952There is one new feature:
953
954 - the Win32 font driver now supports UTF8 (RT 22166)
955 http://www.cpanforum.com/threads/3276
956 http://rt.cpan.org/Ticket/Display.html?id=22166
957
958Several bugs were fixed:
959
960 - the string() method would not output the string "0"
961 http://rt.cpan.org/Public/Bug/Display.html?id=21770
962
963 - fills.c was failing to compile on Solaris 10 (compiler unknown)
964 http://rt.cpan.org/Public/Bug/Display.html?id=21944
965
966 - the gif_disposal and gif_user_input tags weren't being read from
967 the file correctly
968 http://rt.cpan.org/Public/Bug/Display.html?id=22192
969
970 - gif.c was failing to build under MSVC
971 http://rt.cpan.org/Ticket/Display.html?id=23922
972
973 - in some cases strings passed to the string() method were treated as
974 terminated by NUL (chr 0)
975 http://rt.cpan.org/Public/Bug/Display.html?id=21770
976
977 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
978 that's the default build name for zlib on Win32.
979 http://rt.cpan.org/Ticket/Display.html?id=23064
980
981 - search $Config{incpath} for headers too, which we should have been
982 doing all along.
983
984Win32 font driver fixes:
985
986 - the global descent value from bounding box was the wrong sign
987 http://www.cpanforum.com/threads/3276
988
989 - if the first or last glyph overflowed the left or right side of the
990 advance width they would be clipped
991
992
993Imager 0.54 - 14 Sep 2006
994===========
995
996This is primarily a feature release:
997
998 - a new qtype value 'mixing' has been added to the scale()
999 method. This is faster than 'normal', slower than 'preview'. This
1000 is based on the method used by pnmscale, and seems to produce less
1001 blurry results than normal.
1002 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1003
1004 - the rubthrough() method can now render onto images with an alpha
1005 channel.
1006 http://rt.cpan.org/Ticket/Display.html?id=20678
1007
1008 - the read_multi() method now falls back to calling doing a single
1009 image read via the read() method and write_multi() will now fall
1010 back to calling write() if a single image is supplied. This means
1011 you can simply call the read_multi() or write_multi() functions
1012 without having to check if the type is formatted by that method.
1013 http://rt.cpan.org/Ticket/Display.html?id=19457
1014 http://rt.cpan.org/Ticket/Display.html?id=19458
1015
1016 - the GIF loop extension can now be written. If you don't have
1017 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1018 should upgrade.
1019 http://rt.cpan.org/Ticket/Display.html?id=21185
1020
1021 - getscanline() and setscanline() can now read/write palette index
1022 based data from/to the image for paletted images, by setting type to
1023 'index'.
1024 http://rt.cpan.org/Ticket/Display.html?id=20338
1025
1026 - we no longer hassle you to disable GIF support
1027 http://rt.cpan.org/Ticket/Display.html?id=20687
1028
1029 - minor documentation fixes
1030
1031
1032Imager 0.53 - 26 Jul 2006
1033===========
1034
1035This is a bugfix release.
1036
1037Some test code was left in a code path not covered by the test
1038suite. A test was added to cover this code path and the test code was
1039removed.
1040http://rt.cpan.org/Public/Bug/Display.html?id=20705
1041
1042
1043Imager 0.52 - 25 Jul 2006
1044===========
1045
1046This is primarily a feature release, but contains a fair few bug
1047fixes, new features:
1048
1049 - ability to read and write MS Windows ICO and CUR files
1050
1051 - you can now add file format plugins to support new file formats
1052
1053 - add POD coverage tests
1054
1055 - setcolors() and addcolors() now accept color names and so on
1056 instead of requiring Imager::Color objects.
1057 http://rt.cpan.org/Ticket/Display.html?id=20056
1058
1059 - flood_fill() can now fill to a specified border color instead of
1060 just to the area the same color as the seed.
1061 http://rt.cpan.org/Ticket/Display.html?id=19618
1062
1063
1064Bug fixes:
1065
1066 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1067 calculating the advance width.
1068 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1069
1070 - bounding_box for the T1 driver wasn't including leading and
1071 trailing spaces in the bounding box as the other drivers did, it also
1072 produced strange results for empty strings or strings containing only
1073 spaces
1074
1075 - when reading CMYK jpeg images they were being transferred to the
1076 image object as is, producing a four channel image. It only looked ok
1077 due to an old still unfixed Photoshop bug. We now convert from the
1078 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1079 http://rt.cpan.org/Ticket/Display.html?id=20416
1080
1081 - reading a CYMK TIFF would result in a 4 channel image, reading any
1082 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1083 result in an error.
1084 http://rt.cpan.org/Ticket/Display.html?id=20415
1085
1086 - added /usr/local/include to the default include search path, since
1087 we were already searching /usr/local/lib for libraries.
1088
1089And various minor fixes and documentation updates.
1090
1091
1092Imager 0.51 - 23 Apr 2006

1096 a crash
1097 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1098
1099 - fix mis-processing of the src_maxx and src_maxy parameters of the
1100 paste() method
1101 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1102
1103 - fix a problem in Imager's "smart" handling of the color parameter

1113 output is an in-memeory buffer.
1114 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1115
1116 - fixes an incorrect pointer parameter in the PNG code
1117 http://rt.cpan.org/Public/Bug/Display.html?id=18051
