173c91ba 166 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6

169 Test code that managed 3400 10x10 pixel boxes/second sped up to
170 25700 boxes/second.

TC
331 - prevent double-frees when someone creates Imager objects and then

TC
342Bug fixes:
343
344 - the conv filter now enforces that the sum of the coefficients is
345 non-zero. Also, rather than skipping pixels off the edge off the
346 edge of the image, the closest edge pixel is used. Previously
347 dividing by the zero sum of coefficients could cause invalid
348 results or runtime exceptions.
349 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
350 this bug.

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

461 - corrected a reference leak where writing GIFs would leak memory.
462 This could also happen calling to_paletted().

517 - i_scale_axis() wasn't checking the result of i_img_new_ch()
518 resulting in a SIGSEGV when attempting to scale an image to a size
519 too large to fit in memory. This is a NULL pointer access issue,
520 not a buffer overflow.

535This release primarily contains changes to improve ease of use -
536rather than you having to convert images to the appropriate number of
537channels, Imager handles it internally. How to handle drawing colors
538and the default combine mode is a thornier problem left for some other
539release.

544 - moved the imtoc.perl code into Imager::Preprocess
545
546 - paste() and rubthrough() now adapt the source image data to the
547 destination, so you can now safely paste/rubthrough from greyscale
548 images to color images or back, or from alpha channel images to
549 noalpha channels or back.
550 https://rt.cpan.org/Ticket/Display.html?id=30908
551
552 - rubthrough() now falls back to pasting when the source doesn't have
553 an alpha channel. This effectively treats the source as having a
554 max alpha channel, the right thing to do.
555 http://rt.cpan.org/Ticket/Display.html?id=29944
556
557 - re-worked most of the area filling code to use a common set of
558 functions when filling.
559 Corrected normal combine mode.
560 Rewrote most of the combine modes to match the way the SVG draft
561 defines them with respect to a translucent source and destination.
562 Added tests for translucent source and destination.
563 Added tests to check 8-bit/sample and double/sample combines work
564 similarly.

602
603 - handling of the left-over bit for 16-bit/pixel TGA images has been
604 changed to match the behaviour of the GIMP. Previously the bit
605 being set was treated as an opaque pixel, but one user reported a
606 problem with loading such an image. I haven't been able to find any
607 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
608 I'll match it's behaviour. See issue 114913 in the GIMP's
609 bugzilla.

895Bug fixes:
896
897 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
898 was returning an image object with an extra reference, this
899 resulted in a memory leak.
900 http://rt.cpan.org/Ticket/Display.html?id=24992
901
902 - fix rendering on alpha channel images for the FreeType 2.x driver
903 http://rt.cpan.org/Ticket/Display.html?id=11972
904
905 - reading bmp files now consitently handles short reads. You can now
906 supply a parameter to treat a short read as successful and set
907 i_incomplete
908 http://rt.cpan.org/Ticket/Display.html?id=8426
909
910 - previously, reading ASCII PBM files required spaces between samples,
911 even though the format doesn't require that

913 - improved documentation of the unsharpmask filter (I hope)
914 http://rt.cpan.org/Ticket/Display.html?id=25531
915
916 - force flushing of the output from i_tt_dump_names() and test output
917 in t/t35ttfont.t to prevent output from being mixed up.
918 https://rt.cpan.org/Ticket/Display.html?id=24859
919
920 - rewrite a conditional expression as an if() to hopefully work around
921 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.

927Imager 0.55 - 16 Dec 2006
928===========
929
930This is primarily a bug fix release.
931
932Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
933
934There is one new feature:
935
936 - the Win32 font driver now supports UTF8 (RT 22166)
937 http://www.cpanforum.com/threads/3276
938 http://rt.cpan.org/Ticket/Display.html?id=22166
939
940Several bugs were fixed:
941
942 - the string() method would not output the string "0"
943 http://rt.cpan.org/Public/Bug/Display.html?id=21770
944
945 - fills.c was failing to compile on Solaris 10 (compiler unknown)
946 http://rt.cpan.org/Public/Bug/Display.html?id=21944
947
948 - the gif_disposal and gif_user_input tags weren't being read from
949 the file correctly
950 http://rt.cpan.org/Public/Bug/Display.html?id=22192
951
952 - gif.c was failing to build under MSVC
953 http://rt.cpan.org/Ticket/Display.html?id=23922
954
955 - in some cases strings passed to the string() method were treated as
956 terminated by NUL (chr 0)
957 http://rt.cpan.org/Public/Bug/Display.html?id=21770
958
959 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
960 that's the default build name for zlib on Win32.
961 http://rt.cpan.org/Ticket/Display.html?id=23064
962
963 - search $Config{incpath} for headers too, which we should have been
964 doing all along.
965
966Win32 font driver fixes:
967
968 - the global descent value from bounding box was the wrong sign
969 http://www.cpanforum.com/threads/3276
970
971 - if the first or last glyph overflowed the left or right side of the
972 advance width they would be clipped
973
974
975Imager 0.54 - 14 Sep 2006
976===========
977
978This is primarily a feature release:
979
980 - a new qtype value 'mixing' has been added to the scale()
981 method. This is faster than 'normal', slower than 'preview'. This
982 is based on the method used by pnmscale, and seems to produce less
983 blurry results than normal.
984 http://rt.cpan.org/Public/Bug/Display.html?id=20677
985
986 - the rubthrough() method can now render onto images with an alpha
987 channel.
988 http://rt.cpan.org/Ticket/Display.html?id=20678
989
990 - the read_multi() method now falls back to calling doing a single
991 image read via the read() method and write_multi() will now fall
992 back to calling write() if a single image is supplied. This means
993 you can simply call the read_multi() or write_multi() functions
994 without having to check if the type is formatted by that method.
995 http://rt.cpan.org/Ticket/Display.html?id=19457
996 http://rt.cpan.org/Ticket/Display.html?id=19458
997
998 - the GIF loop extension can now be written. If you don't have
999 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1000 should upgrade.
1001 http://rt.cpan.org/Ticket/Display.html?id=21185
1002
1003 - getscanline() and setscanline() can now read/write palette index
1004 based data from/to the image for paletted images, by setting type to
1005 'index'.
1006 http://rt.cpan.org/Ticket/Display.html?id=20338
1007
1008 - we no longer hassle you to disable GIF support
1009 http://rt.cpan.org/Ticket/Display.html?id=20687
1010
1011 - minor documentation fixes
1012
1013
1014Imager 0.53 - 26 Jul 2006
1015===========
1016
1017This is a bugfix release.
1018
1019Some test code was left in a code path not covered by the test
1020suite. A test was added to cover this code path and the test code was
1021removed.
1022http://rt.cpan.org/Public/Bug/Display.html?id=20705
1023
1024
1025Imager 0.52 - 25 Jul 2006
1026===========
1027
1028This is primarily a feature release, but contains a fair few bug
1029fixes, new features:
1030
1031 - ability to read and write MS Windows ICO and CUR files
1032
1033 - you can now add file format plugins to support new file formats
1034
1035 - add POD coverage tests
1036
1037 - setcolors() and addcolors() now accept color names and so on
1038 instead of requiring Imager::Color objects.
1039 http://rt.cpan.org/Ticket/Display.html?id=20056
1040
1041 - flood_fill() can now fill to a specified border color instead of
1042 just to the area the same color as the seed.
1043 http://rt.cpan.org/Ticket/Display.html?id=19618
1044
1045
1046Bug fixes:
1047
1048 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1049 calculating the advance width.
1050 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1051
1052 - bounding_box for the T1 driver wasn't including leading and
1053 trailing spaces in the bounding box as the other drivers did, it also
1054 produced strange results for empty strings or strings containing only
1055 spaces
1056
1057 - when reading CMYK jpeg images they were being transferred to the
1058 image object as is, producing a four channel image. It only looked ok
1059 due to an old still unfixed Photoshop bug. We now convert from the
1060 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1061 http://rt.cpan.org/Ticket/Display.html?id=20416
1062
1063 - reading a CYMK TIFF would result in a 4 channel image, reading any
1064 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1065 result in an error.
1066 http://rt.cpan.org/Ticket/Display.html?id=20415
1067
1068 - added /usr/local/include to the default include search path, since
1069 we were already searching /usr/local/lib for libraries.
1070
1071And various minor fixes and documentation updates.
1072
1073
1074Imager 0.51 - 23 Apr 2006

1078 a crash
1079 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1080
1081 - fix mis-processing of the src_maxx and src_maxy parameters of the
1082 paste() method
1083 http://rt.cpan.org/Public/Bug/Display.html?id=18712

1095 output is an in-memeory buffer.
1096 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1097
1098 - fixes an incorrect pointer parameter in the PNG code
