173c91ba 156 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
157 used for color translation on Unix-like systems, and the fix

159 Test code that managed 3400 10x10 pixel boxes/second sped up to
160 25700 boxes/second.

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

330 another fill.
331

TC
332Bug fixes:
333
334 - the conv filter now enforces that the sum of the coefficients is
335 non-zero. Also, rather than skipping pixels off the edge off the
336 edge of the image, the closest edge pixel is used. Previously
337 dividing by the zero sum of coefficients could cause invalid
338 results or runtime exceptions.
339 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
340 this bug.

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

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

525This release primarily contains changes to improve ease of use -
526rather than you having to convert images to the appropriate number of
527channels, Imager handles it internally. How to handle drawing colors
528and the default combine mode is a thornier problem left for some other
529release.

TC
534 - moved the imtoc.perl code into Imager::Preprocess
535
536 - paste() and rubthrough() now adapt the source image data to the
537 destination, so you can now safely paste/rubthrough from greyscale
538 images to color images or back, or from alpha channel images to
539 noalpha channels or back.
540 https://rt.cpan.org/Ticket/Display.html?id=30908
541
542 - rubthrough() now falls back to pasting when the source doesn't have
543 an alpha channel. This effectively treats the source as having a
544 max alpha channel, the right thing to do.
545 http://rt.cpan.org/Ticket/Display.html?id=29944
546
547 - re-worked most of the area filling code to use a common set of
548 functions when filling.
549 Corrected normal combine mode.
550 Rewrote most of the combine modes to match the way the SVG draft
551 defines them with respect to a translucent source and destination.
552 Added tests for translucent source and destination.
553 Added tests to check 8-bit/sample and double/sample combines work
554 similarly.

590 - some TGA images weren't being detected correctly as TGA images
591 https://rt.cpan.org/Ticket/Display.html?id=32925
592
593 - handling of the left-over bit for 16-bit/pixel TGA images has been
594 changed to match the behaviour of the GIMP. Previously the bit
595 being set was treated as an opaque pixel, but one user reported a
596 problem with loading such an image. I haven't been able to find any
597 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
598 I'll match it's behaviour. See issue 114913 in the GIMP's
599 bugzilla.

896 supply a parameter to treat a short read as successful and set
897 i_incomplete

899
900 - previously, reading ASCII PBM files required spaces between samples,
901 even though the format doesn't require that

903 - improved documentation of the unsharpmask filter (I hope)
904 http://rt.cpan.org/Ticket/Display.html?id=25531
905
906 - force flushing of the output from i_tt_dump_names() and test output
907 in t/t35ttfont.t to prevent output from being mixed up.
908 https://rt.cpan.org/Ticket/Display.html?id=24859
909
910 - rewrite a conditional expression as an if() to hopefully work around
911 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
912 https://rt.cpan.org/Ticket/Display.html?id=25561
913
914 - avoid Data::Dumper in regops.perl to support older releases of perl

917Imager 0.55 - 16 Dec 2006
918===========
919
920This is primarily a bug fix release.
921
922Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
923
924There is one new feature:
925
926 - the Win32 font driver now supports UTF8 (RT 22166)
927 http://www.cpanforum.com/threads/3276
928 http://rt.cpan.org/Ticket/Display.html?id=22166
929
930Several bugs were fixed:
931
932 - the string() method would not output the string "0"
933 http://rt.cpan.org/Public/Bug/Display.html?id=21770
934
935 - fills.c was failing to compile on Solaris 10 (compiler unknown)
936 http://rt.cpan.org/Public/Bug/Display.html?id=21944
937
938 - the gif_disposal and gif_user_input tags weren't being read from
939 the file correctly
940 http://rt.cpan.org/Public/Bug/Display.html?id=22192
941
942 - gif.c was failing to build under MSVC
943 http://rt.cpan.org/Ticket/Display.html?id=23922
944
945 - in some cases strings passed to the string() method were treated as
946 terminated by NUL (chr 0)
947 http://rt.cpan.org/Public/Bug/Display.html?id=21770
948
949 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
950 that's the default build name for zlib on Win32.
951 http://rt.cpan.org/Ticket/Display.html?id=23064
952
953 - search $Config{incpath} for headers too, which we should have been
954 doing all along.
955
956Win32 font driver fixes:
957
958 - the global descent value from bounding box was the wrong sign
959 http://www.cpanforum.com/threads/3276
960
961 - if the first or last glyph overflowed the left or right side of the
962 advance width they would be clipped
963
964
965Imager 0.54 - 14 Sep 2006
966===========
967
968This is primarily a feature release:
969
970 - a new qtype value 'mixing' has been added to the scale()
971 method. This is faster than 'normal', slower than 'preview'. This
972 is based on the method used by pnmscale, and seems to produce less
973 blurry results than normal.
974 http://rt.cpan.org/Public/Bug/Display.html?id=20677
975
976 - the rubthrough() method can now render onto images with an alpha
977 channel.
978 http://rt.cpan.org/Ticket/Display.html?id=20678
979
980 - the read_multi() method now falls back to calling doing a single
981 image read via the read() method and write_multi() will now fall
982 back to calling write() if a single image is supplied. This means
983 you can simply call the read_multi() or write_multi() functions
984 without having to check if the type is formatted by that method.
985 http://rt.cpan.org/Ticket/Display.html?id=19457
986 http://rt.cpan.org/Ticket/Display.html?id=19458
987
988 - the GIF loop extension can now be written. If you don't have
989 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
990 should upgrade.
991 http://rt.cpan.org/Ticket/Display.html?id=21185
992
993 - getscanline() and setscanline() can now read/write palette index
994 based data from/to the image for paletted images, by setting type to
995 'index'.
996 http://rt.cpan.org/Ticket/Display.html?id=20338
997
998 - we no longer hassle you to disable GIF support
999 http://rt.cpan.org/Ticket/Display.html?id=20687
1000
1001 - minor documentation fixes
1002
1003
1004Imager 0.53 - 26 Jul 2006
1005===========
1006
1007This is a bugfix release.
1008
1009Some test code was left in a code path not covered by the test
1010suite. A test was added to cover this code path and the test code was
1011removed.
1012http://rt.cpan.org/Public/Bug/Display.html?id=20705
1013
1014
1015Imager 0.52 - 25 Jul 2006
1016===========
1017
1018This is primarily a feature release, but contains a fair few bug
1019fixes, new features:
1020
1021 - ability to read and write MS Windows ICO and CUR files
1022
1023 - you can now add file format plugins to support new file formats
1024
1025 - add POD coverage tests
1026
1027 - setcolors() and addcolors() now accept color names and so on
1028 instead of requiring Imager::Color objects.
1029 http://rt.cpan.org/Ticket/Display.html?id=20056
1030
1031 - flood_fill() can now fill to a specified border color instead of
1032 just to the area the same color as the seed.
1033 http://rt.cpan.org/Ticket/Display.html?id=19618
1034
1035
1036Bug fixes:
1037
1038 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1039 calculating the advance width.
1040 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1041
1042 - bounding_box for the T1 driver wasn't including leading and
1043 trailing spaces in the bounding box as the other drivers did, it also
1044 produced strange results for empty strings or strings containing only
1045 spaces
1046
1047 - when reading CMYK jpeg images they were being transferred to the
1048 image object as is, producing a four channel image. It only looked ok
1049 due to an old still unfixed Photoshop bug. We now convert from the
1050 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1051 http://rt.cpan.org/Ticket/Display.html?id=20416
1052
1053 - reading a CYMK TIFF would result in a 4 channel image, reading any
1054 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1055 result in an error.
1056 http://rt.cpan.org/Ticket/Display.html?id=20415
1057
1058 - added /usr/local/include to the default include search path, since
1059 we were already searching /usr/local/lib for libraries.
1060
1061And various minor fixes and documentation updates.
1062
1063
1064Imager 0.51 - 23 Apr 2006

1068 a crash
1069 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1070
1071 - fix mis-processing of the src_maxx and src_maxy parameters of the
1072 paste() method
1073 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1074
1075 - fix a problem in Imager's "smart" handling of the color parameter

1085 output is an in-memeory buffer.
1086 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1087
1088 - fixes an incorrect pointer parameter in the PNG code
1089 http://rt.cpan.org/Public/Bug/Display.html?id=18051
