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.

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.

184 Test code that managed 3400 10x10 pixel boxes/second sped up to
185 25700 boxes/second.

346 - prevent double-frees when someone creates Imager objects and then

357Bug fixes:
358
359 - the conv filter now enforces that the sum of the coefficients is
360 non-zero. Also, rather than skipping pixels off the edge off the
361 edge of the image, the closest edge pixel is used. Previously
362 dividing by the zero sum of coefficients could cause invalid
363 results or runtime exceptions.
364 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
365 this bug.

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

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

550This release primarily contains changes to improve ease of use -
551rather than you having to convert images to the appropriate number of
552channels, Imager handles it internally. How to handle drawing colors
553and the default combine mode is a thornier problem left for some other
554release.

TC
559 - moved the imtoc.perl code into Imager::Preprocess
560
561 - paste() and rubthrough() now adapt the source image data to the
562 destination, so you can now safely paste/rubthrough from greyscale
563 images to color images or back, or from alpha channel images to
564 noalpha channels or back.
565 https://rt.cpan.org/Ticket/Display.html?id=30908
566
567 - rubthrough() now falls back to pasting when the source doesn't have
568 an alpha channel. This effectively treats the source as having a
569 max alpha channel, the right thing to do.
570 http://rt.cpan.org/Ticket/Display.html?id=29944
571
572 - re-worked most of the area filling code to use a common set of
573 functions when filling.
574 Corrected normal combine mode.
575 Rewrote most of the combine modes to match the way the SVG draft
576 defines them with respect to a translucent source and destination.
577 Added tests for translucent source and destination.
578 Added tests to check 8-bit/sample and double/sample combines work
579 similarly.

615 - some TGA images weren't being detected correctly as TGA images

617
618 - handling of the left-over bit for 16-bit/pixel TGA images has been
619 changed to match the behaviour of the GIMP. Previously the bit
620 being set was treated as an opaque pixel, but one user reported a
621 problem with loading such an image. I haven't been able to find any
622 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
623 I'll match it's behaviour. See issue 114913 in the GIMP's
624 bugzilla.

634 - the old dynaload code used Mach API functions to load dynamic
635 libraries on Mac OS X. These APIs have been deprecated in OS X
636 10.5 and were causing some build problems.

638 will need version 10.3 or later of OS X.

910Bug fixes:
911
912 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
913 was returning an image object with an extra reference, this
914 resulted in a memory leak.
915 http://rt.cpan.org/Ticket/Display.html?id=24992
916
917 - fix rendering on alpha channel images for the FreeType 2.x driver
918 http://rt.cpan.org/Ticket/Display.html?id=11972
919
920 - reading bmp files now consitently handles short reads. You can now
921 supply a parameter to treat a short read as successful and set
922 i_incomplete
923 http://rt.cpan.org/Ticket/Display.html?id=8426
924
925 - previously, reading ASCII PBM files required spaces between samples,
926 even though the format doesn't require that
927

TC
928 - improved documentation of the unsharpmask filter (I hope)
929 http://rt.cpan.org/Ticket/Display.html?id=25531
930
931 - force flushing of the output from i_tt_dump_names() and test output
932 in t/t35ttfont.t to prevent output from being mixed up.
933 https://rt.cpan.org/Ticket/Display.html?id=24859
934
935 - rewrite a conditional expression as an if() to hopefully work around
936 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.

942Imager 0.55 - 16 Dec 2006
943===========
944
945This is primarily a bug fix release.
946
947Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
948
949There is one new feature:
950
951 - the Win32 font driver now supports UTF8 (RT 22166)
952 http://www.cpanforum.com/threads/3276
953 http://rt.cpan.org/Ticket/Display.html?id=22166
954
955Several bugs were fixed:
956
957 - the string() method would not output the string "0"
958 http://rt.cpan.org/Public/Bug/Display.html?id=21770
959
960 - fills.c was failing to compile on Solaris 10 (compiler unknown)
961 http://rt.cpan.org/Public/Bug/Display.html?id=21944
962
963 - the gif_disposal and gif_user_input tags weren't being read from
964 the file correctly
965 http://rt.cpan.org/Public/Bug/Display.html?id=22192
966
967 - gif.c was failing to build under MSVC
968 http://rt.cpan.org/Ticket/Display.html?id=23922
969
970 - in some cases strings passed to the string() method were treated as
971 terminated by NUL (chr 0)
972 http://rt.cpan.org/Public/Bug/Display.html?id=21770
973
974 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
975 that's the default build name for zlib on Win32.
976 http://rt.cpan.org/Ticket/Display.html?id=23064
977
978 - search $Config{incpath} for headers too, which we should have been
979 doing all along.
980
981Win32 font driver fixes:
982
983 - the global descent value from bounding box was the wrong sign
984 http://www.cpanforum.com/threads/3276
985
986 - if the first or last glyph overflowed the left or right side of the
987 advance width they would be clipped
988
989
990Imager 0.54 - 14 Sep 2006
991===========
992
993This is primarily a feature release:
994
995 - a new qtype value 'mixing' has been added to the scale()
996 method. This is faster than 'normal', slower than 'preview'. This
997 is based on the method used by pnmscale, and seems to produce less
998 blurry results than normal.
999 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1000
1001 - the rubthrough() method can now render onto images with an alpha
1002 channel.
1003 http://rt.cpan.org/Ticket/Display.html?id=20678
1004
1005 - the read_multi() method now falls back to calling doing a single
1006 image read via the read() method and write_multi() will now fall
1007 back to calling write() if a single image is supplied. This means
1008 you can simply call the read_multi() or write_multi() functions
1009 without having to check if the type is formatted by that method.
1010 http://rt.cpan.org/Ticket/Display.html?id=19457
1011 http://rt.cpan.org/Ticket/Display.html?id=19458
1012
1013 - the GIF loop extension can now be written. If you don't have
1014 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1015 should upgrade.
1016 http://rt.cpan.org/Ticket/Display.html?id=21185
1017
1018 - getscanline() and setscanline() can now read/write palette index
1019 based data from/to the image for paletted images, by setting type to
1020 'index'.
1021 http://rt.cpan.org/Ticket/Display.html?id=20338
1022
1023 - we no longer hassle you to disable GIF support
1024 http://rt.cpan.org/Ticket/Display.html?id=20687
1025
1026 - minor documentation fixes
1027
1028
1029Imager 0.53 - 26 Jul 2006
1030===========
1031
1032This is a bugfix release.
1033
1034Some test code was left in a code path not covered by the test
1035suite. A test was added to cover this code path and the test code was
1036removed.
1037http://rt.cpan.org/Public/Bug/Display.html?id=20705
1038
1039
1040Imager 0.52 - 25 Jul 2006
1041===========
1042
1043This is primarily a feature release, but contains a fair few bug
1044fixes, new features:
1045
1046 - ability to read and write MS Windows ICO and CUR files
1047
1048 - you can now add file format plugins to support new file formats
1049
1050 - add POD coverage tests
1051
1052 - setcolors() and addcolors() now accept color names and so on
1053 instead of requiring Imager::Color objects.
1054 http://rt.cpan.org/Ticket/Display.html?id=20056
1055
1056 - flood_fill() can now fill to a specified border color instead of
1057 just to the area the same color as the seed.
1058 http://rt.cpan.org/Ticket/Display.html?id=19618
1059
1060
1061Bug fixes:
1062
1063 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1064 calculating the advance width.
1065 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1066
1067 - bounding_box for the T1 driver wasn't including leading and
1068 trailing spaces in the bounding box as the other drivers did, it also
1069 produced strange results for empty strings or strings containing only
1070 spaces
1071
1072 - when reading CMYK jpeg images they were being transferred to the
1073 image object as is, producing a four channel image. It only looked ok
1074 due to an old still unfixed Photoshop bug. We now convert from the
1075 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1076 http://rt.cpan.org/Ticket/Display.html?id=20416
1077
1078 - reading a CYMK TIFF would result in a 4 channel image, reading any
1079 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1080 result in an error.
1081 http://rt.cpan.org/Ticket/Display.html?id=20415
1082
1083 - added /usr/local/include to the default include search path, since
1084 we were already searching /usr/local/lib for libraries.
1085
1086And various minor fixes and documentation updates.
1087
1088

1093 a crash
1094 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1095
1096 - fix mis-processing of the src_maxx and src_maxy parameters of the
1097 paste() method
1098 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1099
