316Bug fixes:
317
318 - the conv filter now enforces that the sum of the coefficients is
319 non-zero. Also, rather than skipping pixels off the edge off the
320 edge of the image, the closest edge pixel is used. Previously
321 dividing by the zero sum of coefficients could cause invalid
322 results or runtime exceptions.
323 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
324 this bug.

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

481 - Possible security issue: The floating point sample path for image

487 - check that the result of fileno($fh) is defined rather than simply
488 true when read() or write() is supplied with an fh parameter.
489 http://rt.cpan.org/Ticket/Display.html?id=35139
490
491 - i_scale_axis() wasn't checking the result of i_img_new_ch()
492 resulting in a SIGSEGV when attempting to scale an image to a size
493 too large to fit in memory. This is a NULL pointer access issue,
494 not a buffer overflow.
495 Added a check for the failure.
496 scale_calculate() (and hence scale()) will now fail if any of the
497 scale size parameters are a reference.

509This release primarily contains changes to improve ease of use -
510rather than you having to convert images to the appropriate number of
511channels, Imager handles it internally. How to handle drawing colors
512and the default combine mode is a thornier problem left for some other
513release.

TC
518 - moved the imtoc.perl code into Imager::Preprocess
519
520 - paste() and rubthrough() now adapt the source image data to the
521 destination, so you can now safely paste/rubthrough from greyscale
522 images to color images or back, or from alpha channel images to
523 noalpha channels or back.
524 https://rt.cpan.org/Ticket/Display.html?id=30908
525
526 - rubthrough() now falls back to pasting when the source doesn't have
527 an alpha channel. This effectively treats the source as having a
528 max alpha channel, the right thing to do.
529 http://rt.cpan.org/Ticket/Display.html?id=29944
530
531 - re-worked most of the area filling code to use a common set of
532 functions when filling.
533 Corrected normal combine mode.
534 Rewrote most of the combine modes to match the way the SVG draft
535 defines them with respect to a translucent source and destination.
536 Added tests for translucent source and destination.
537 Added tests to check 8-bit/sample and double/sample combines work
538 similarly.

574 - some TGA images weren't being detected correctly as TGA images
575 https://rt.cpan.org/Ticket/Display.html?id=32925
576
577 - handling of the left-over bit for 16-bit/pixel TGA images has been
578 changed to match the behaviour of the GIMP. Previously the bit
579 being set was treated as an opaque pixel, but one user reported a
580 problem with loading such an image. I haven't been able to find any
581 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
582 I'll match it's behaviour. See issue 114913 in the GIMP's
583 bugzilla.

593 - the old dynaload code used Mach API functions to load dynamic
594 libraries on Mac OS X. These APIs have been deprecated in OS X
595 10.5 and were causing some build problems.

597 will need version 10.3 or later of OS X.

901Imager 0.55 - 16 Dec 2006
902===========
903
904This is primarily a bug fix release.
905
906Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
907
908There is one new feature:
909
910 - the Win32 font driver now supports UTF8 (RT 22166)
911 http://www.cpanforum.com/threads/3276
912 http://rt.cpan.org/Ticket/Display.html?id=22166
913
914Several bugs were fixed:
915
916 - the string() method would not output the string "0"
917 http://rt.cpan.org/Public/Bug/Display.html?id=21770
918
919 - fills.c was failing to compile on Solaris 10 (compiler unknown)
920 http://rt.cpan.org/Public/Bug/Display.html?id=21944
921
922 - the gif_disposal and gif_user_input tags weren't being read from
923 the file correctly
924 http://rt.cpan.org/Public/Bug/Display.html?id=22192
925
926 - gif.c was failing to build under MSVC
927 http://rt.cpan.org/Ticket/Display.html?id=23922
928
929 - in some cases strings passed to the string() method were treated as
930 terminated by NUL (chr 0)
931 http://rt.cpan.org/Public/Bug/Display.html?id=21770
932
933 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
934 that's the default build name for zlib on Win32.
935 http://rt.cpan.org/Ticket/Display.html?id=23064
936
937 - search $Config{incpath} for headers too, which we should have been
938 doing all along.
939
940Win32 font driver fixes:
941
942 - the global descent value from bounding box was the wrong sign
943 http://www.cpanforum.com/threads/3276
944
945 - if the first or last glyph overflowed the left or right side of the
946 advance width they would be clipped
947
948
949Imager 0.54 - 14 Sep 2006
950===========
951
952This is primarily a feature release:
953
954 - a new qtype value 'mixing' has been added to the scale()
955 method. This is faster than 'normal', slower than 'preview'. This
956 is based on the method used by pnmscale, and seems to produce less
957 blurry results than normal.
958 http://rt.cpan.org/Public/Bug/Display.html?id=20677
959
960 - the rubthrough() method can now render onto images with an alpha
961 channel.
962 http://rt.cpan.org/Ticket/Display.html?id=20678
963
964 - the read_multi() method now falls back to calling doing a single
965 image read via the read() method and write_multi() will now fall
966 back to calling write() if a single image is supplied. This means
967 you can simply call the read_multi() or write_multi() functions
968 without having to check if the type is formatted by that method.
969 http://rt.cpan.org/Ticket/Display.html?id=19457
970 http://rt.cpan.org/Ticket/Display.html?id=19458
971
972 - the GIF loop extension can now be written. If you don't have
973 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
974 should upgrade.
975 http://rt.cpan.org/Ticket/Display.html?id=21185
976
977 - getscanline() and setscanline() can now read/write palette index
978 based data from/to the image for paletted images, by setting type to
979 'index'.
980 http://rt.cpan.org/Ticket/Display.html?id=20338
981
982 - we no longer hassle you to disable GIF support
983 http://rt.cpan.org/Ticket/Display.html?id=20687
984
985 - minor documentation fixes
986
987
988Imager 0.53 - 26 Jul 2006
989===========
990
991This is a bugfix release.
992
993Some test code was left in a code path not covered by the test
994suite. A test was added to cover this code path and the test code was
995removed.

997
998
999Imager 0.52 - 25 Jul 2006
1000===========
1001
1002This is primarily a feature release, but contains a fair few bug
1003fixes, new features:
1004
1005 - ability to read and write MS Windows ICO and CUR files
1006
1007 - you can now add file format plugins to support new file formats
1008
1009 - add POD coverage tests
1010
1011 - setcolors() and addcolors() now accept color names and so on
1012 instead of requiring Imager::Color objects.
1013 http://rt.cpan.org/Ticket/Display.html?id=20056
1014
1015 - flood_fill() can now fill to a specified border color instead of
1016 just to the area the same color as the seed.
1017 http://rt.cpan.org/Ticket/Display.html?id=19618
1018
1019
1020Bug fixes:
1021
1022 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1023 calculating the advance width.
1024 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1025
1026 - bounding_box for the T1 driver wasn't including leading and
1027 trailing spaces in the bounding box as the other drivers did, it also
1028 produced strange results for empty strings or strings containing only
1029 spaces
1030
1031 - when reading CMYK jpeg images they were being transferred to the
1032 image object as is, producing a four channel image. It only looked ok
1033 due to an old still unfixed Photoshop bug. We now convert from the
1034 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1035 http://rt.cpan.org/Ticket/Display.html?id=20416
1036
1037 - reading a CYMK TIFF would result in a 4 channel image, reading any
1038 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1039 result in an error.
1040 http://rt.cpan.org/Ticket/Display.html?id=20415
1041
1042 - added /usr/local/include to the default include search path, since
1043 we were already searching /usr/local/lib for libraries.
1044
1045And various minor fixes and documentation updates.
1046
