149
173c91ba 150 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
151 used for color translation on Unix-like systems, and the fix
152 improves performance of supplying colors by name by about 80 times.
153 Test code that managed 3400 10x10 pixel boxes/second sped up to
154 25700 boxes/second.

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

TC
315 - prevent double-frees when someone creates Imager objects and then
316 creates a thread. Note: this just handles some simple cases,

TC
326Bug fixes:
327
328 - the conv filter now enforces that the sum of the coefficients is
329 non-zero. Also, rather than skipping pixels off the edge off the
330 edge of the image, the closest edge pixel is used. Previously
331 dividing by the zero sum of coefficients could cause invalid
332 results or runtime exceptions.
333 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
334 this bug.

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

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

519This release primarily contains changes to improve ease of use -
520rather than you having to convert images to the appropriate number of
521channels, Imager handles it internally. How to handle drawing colors
522and the default combine mode is a thornier problem left for some other
523release.

TC
528 - moved the imtoc.perl code into Imager::Preprocess
529
530 - paste() and rubthrough() now adapt the source image data to the
531 destination, so you can now safely paste/rubthrough from greyscale
532 images to color images or back, or from alpha channel images to
533 noalpha channels or back.
534 https://rt.cpan.org/Ticket/Display.html?id=30908
535
536 - rubthrough() now falls back to pasting when the source doesn't have
537 an alpha channel. This effectively treats the source as having a
538 max alpha channel, the right thing to do.
539 http://rt.cpan.org/Ticket/Display.html?id=29944
540
541 - re-worked most of the area filling code to use a common set of
542 functions when filling.
543 Corrected normal combine mode.
544 Rewrote most of the combine modes to match the way the SVG draft
545 defines them with respect to a translucent source and destination.
546 Added tests for translucent source and destination.
547 Added tests to check 8-bit/sample and double/sample combines work
548 similarly.

586
587 - handling of the left-over bit for 16-bit/pixel TGA images has been
588 changed to match the behaviour of the GIMP. Previously the bit
589 being set was treated as an opaque pixel, but one user reported a
590 problem with loading such an image. I haven't been able to find any
591 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
592 I'll match it's behaviour. See issue 114913 in the GIMP's
593 bugzilla.

899
900 - force flushing of the output from i_tt_dump_names() and test output
901 in t/t35ttfont.t to prevent output from being mixed up.
902 https://rt.cpan.org/Ticket/Display.html?id=24859
903
904 - rewrite a conditional expression as an if() to hopefully work around
905 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.

911Imager 0.55 - 16 Dec 2006
912===========
913
914This is primarily a bug fix release.
915
916Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
917
918There is one new feature:
919
920 - the Win32 font driver now supports UTF8 (RT 22166)
921 http://www.cpanforum.com/threads/3276
922 http://rt.cpan.org/Ticket/Display.html?id=22166
923
924Several bugs were fixed:
925
926 - the string() method would not output the string "0"
927 http://rt.cpan.org/Public/Bug/Display.html?id=21770
928
929 - fills.c was failing to compile on Solaris 10 (compiler unknown)
930 http://rt.cpan.org/Public/Bug/Display.html?id=21944
931
932 - the gif_disposal and gif_user_input tags weren't being read from
933 the file correctly
934 http://rt.cpan.org/Public/Bug/Display.html?id=22192
935
936 - gif.c was failing to build under MSVC
937 http://rt.cpan.org/Ticket/Display.html?id=23922
938
939 - in some cases strings passed to the string() method were treated as
940 terminated by NUL (chr 0)
941 http://rt.cpan.org/Public/Bug/Display.html?id=21770
942
943 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
944 that's the default build name for zlib on Win32.
945 http://rt.cpan.org/Ticket/Display.html?id=23064
946
947 - search $Config{incpath} for headers too, which we should have been
948 doing all along.
949
950Win32 font driver fixes:
951
952 - the global descent value from bounding box was the wrong sign
953 http://www.cpanforum.com/threads/3276
954
955 - if the first or last glyph overflowed the left or right side of the
956 advance width they would be clipped
957
958
959Imager 0.54 - 14 Sep 2006
960===========
961
962This is primarily a feature release:
963
964 - a new qtype value 'mixing' has been added to the scale()
965 method. This is faster than 'normal', slower than 'preview'. This
966 is based on the method used by pnmscale, and seems to produce less
967 blurry results than normal.
968 http://rt.cpan.org/Public/Bug/Display.html?id=20677
969
970 - the rubthrough() method can now render onto images with an alpha
971 channel.
972 http://rt.cpan.org/Ticket/Display.html?id=20678
973
974 - the read_multi() method now falls back to calling doing a single
975 image read via the read() method and write_multi() will now fall
976 back to calling write() if a single image is supplied. This means
977 you can simply call the read_multi() or write_multi() functions
978 without having to check if the type is formatted by that method.
979 http://rt.cpan.org/Ticket/Display.html?id=19457
980 http://rt.cpan.org/Ticket/Display.html?id=19458
981
982 - the GIF loop extension can now be written. If you don't have
983 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
984 should upgrade.
985 http://rt.cpan.org/Ticket/Display.html?id=21185
986
987 - getscanline() and setscanline() can now read/write palette index
988 based data from/to the image for paletted images, by setting type to
989 'index'.
990 http://rt.cpan.org/Ticket/Display.html?id=20338
991
992 - we no longer hassle you to disable GIF support
993 http://rt.cpan.org/Ticket/Display.html?id=20687
994
995 - minor documentation fixes
996
997
998Imager 0.53 - 26 Jul 2006
999===========
1000
1001This is a bugfix release.
1002
1003Some test code was left in a code path not covered by the test
1004suite. A test was added to cover this code path and the test code was
1005removed.
1006http://rt.cpan.org/Public/Bug/Display.html?id=20705
1007
1008
1009Imager 0.52 - 25 Jul 2006
1010===========
1011
1012This is primarily a feature release, but contains a fair few bug
1013fixes, new features:
1014
1015 - ability to read and write MS Windows ICO and CUR files
1016
1017 - you can now add file format plugins to support new file formats
1018
1019 - add POD coverage tests
1020
1021 - setcolors() and addcolors() now accept color names and so on
1022 instead of requiring Imager::Color objects.
1023 http://rt.cpan.org/Ticket/Display.html?id=20056
1024
1025 - flood_fill() can now fill to a specified border color instead of
1026 just to the area the same color as the seed.
1027 http://rt.cpan.org/Ticket/Display.html?id=19618
1028
1029
1030Bug fixes:
1031
1032 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1033 calculating the advance width.
1034 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1035
1036 - bounding_box for the T1 driver wasn't including leading and
1037 trailing spaces in the bounding box as the other drivers did, it also
1038 produced strange results for empty strings or strings containing only
1039 spaces
1040
1041 - when reading CMYK jpeg images they were being transferred to the
1042 image object as is, producing a four channel image. It only looked ok
1043 due to an old still unfixed Photoshop bug. We now convert from the
1044 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1045 http://rt.cpan.org/Ticket/Display.html?id=20416
1046
1047 - reading a CYMK TIFF would result in a 4 channel image, reading any
1048 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1049 result in an error.
1050 http://rt.cpan.org/Ticket/Display.html?id=20415
1051
1052 - added /usr/local/include to the default include search path, since
1053 we were already searching /usr/local/lib for libraries.
1054
1055And various minor fixes and documentation updates.
1056
1057

1064
1065 - fix mis-processing of the src_maxx and src_maxy parameters of the
1066 paste() method
1067 http://rt.cpan.org/Public/Bug/Display.html?id=18712
