34 - compose() with the target, source or mask position off the top or

37
38 - compose() now returns a useful error message on a non-positive

47Bug fixes:
48
49 - eliminate calls to i_has_format() from the test suite, since it's
50 no longer a useful way to check for file format support. Eliminate
51 i_has_format() from the functions exposed via XS.

53
7540f84a
TC
54 - eliminate calls to note(), which isn't in the (very old) version of
55 Test::More we have as a pre-requisite. note() is modern enough
56 that I don't feel a need to require a Test::More upgrade for it.
57 https://rt.cpan.org/Ticket/Display.html?id=65864

69 downgrade the version in this file.
70 https://rt.cpan.org/Ticket/Display.html?id=66250
71
72 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
73 that option for the directories that would normally go in
74 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

239
173c91ba 240 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
241 used for color translation on Unix-like systems, and the fix
242 improves performance of supplying colors by name by about 80 times.
243 Test code that managed 3400 10x10 pixel boxes/second sped up to
244 25700 boxes/second.

416Bug fixes:
417
418 - the conv filter now enforces that the sum of the coefficients is
419 non-zero. Also, rather than skipping pixels off the edge off the
420 edge of the image, the closest edge pixel is used. Previously
421 dividing by the zero sum of coefficients could cause invalid
422 results or runtime exceptions.
423 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
424 this bug.

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

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

587 - check that the result of fileno($fh) is defined rather than simply
588 true when read() or write() is supplied with an fh parameter.
589 http://rt.cpan.org/Ticket/Display.html?id=35139
590
591 - i_scale_axis() wasn't checking the result of i_img_new_ch()
592 resulting in a SIGSEGV when attempting to scale an image to a size
593 too large to fit in memory. This is a NULL pointer access issue,
594 not a buffer overflow.
595 Added a check for the failure.
596 scale_calculate() (and hence scale()) will now fail if any of the
597 scale size parameters are a reference.

242d7497
TC
609This release primarily contains changes to improve ease of use -
610rather than you having to convert images to the appropriate number of
611channels, Imager handles it internally. How to handle drawing colors
612and the default combine mode is a thornier problem left for some other
613release.

TC
618 - moved the imtoc.perl code into Imager::Preprocess
619
620 - paste() and rubthrough() now adapt the source image data to the
621 destination, so you can now safely paste/rubthrough from greyscale
622 images to color images or back, or from alpha channel images to
623 noalpha channels or back.
624 https://rt.cpan.org/Ticket/Display.html?id=30908
625
626 - rubthrough() now falls back to pasting when the source doesn't have
627 an alpha channel. This effectively treats the source as having a
628 max alpha channel, the right thing to do.
629 http://rt.cpan.org/Ticket/Display.html?id=29944
630
631 - re-worked most of the area filling code to use a common set of
632 functions when filling.
633 Corrected normal combine mode.
634 Rewrote most of the combine modes to match the way the SVG draft
635 defines them with respect to a translucent source and destination.
636 Added tests for translucent source and destination.
637 Added tests to check 8-bit/sample and double/sample combines work
638 similarly.

662 - mixing qtype scaling now sets all channels of a pixel to zero if

670 I'm not changing the #! lines of the sample code, since it's sample
671 code, not intended for installation.

TC
674 - some TGA images weren't being detected correctly as TGA images
675 https://rt.cpan.org/Ticket/Display.html?id=32925
676
677 - handling of the left-over bit for 16-bit/pixel TGA images has been
678 changed to match the behaviour of the GIMP. Previously the bit
679 being set was treated as an opaque pixel, but one user reported a
680 problem with loading such an image. I haven't been able to find any
681 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
682 I'll match it's behaviour. See issue 114913 in the GIMP's
683 bugzilla.

693 - the old dynaload code used Mach API functions to load dynamic
694 libraries on Mac OS X. These APIs have been deprecated in OS X
695 10.5 and were causing some build problems.
696 So henceforth Imager uses the dlopen() family of functions, and you
697 will need version 10.3 or later of OS X.

1001Imager 0.55 - 16 Dec 2006
1002===========
1003
1004This is primarily a bug fix release.
1005
1006Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1007
1008There is one new feature:
1009
1010 - the Win32 font driver now supports UTF8 (RT 22166)
1011 http://www.cpanforum.com/threads/3276
1012 http://rt.cpan.org/Ticket/Display.html?id=22166
1013
1014Several bugs were fixed:
1015
1016 - the string() method would not output the string "0"
1017 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1018
1019 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1020 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1021
1022 - the gif_disposal and gif_user_input tags weren't being read from
1023 the file correctly
1024 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1025
1026 - gif.c was failing to build under MSVC
1027 http://rt.cpan.org/Ticket/Display.html?id=23922
1028
1029 - in some cases strings passed to the string() method were treated as
1030 terminated by NUL (chr 0)
1031 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1032
1033 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1034 that's the default build name for zlib on Win32.
1035 http://rt.cpan.org/Ticket/Display.html?id=23064
1036
1037 - search $Config{incpath} for headers too, which we should have been
1038 doing all along.
1039
1040Win32 font driver fixes:
1041
1042 - the global descent value from bounding box was the wrong sign
1043 http://www.cpanforum.com/threads/3276
1044
1045 - if the first or last glyph overflowed the left or right side of the
1046 advance width they would be clipped
1047
1048
1049Imager 0.54 - 14 Sep 2006
1050===========
1051
1052This is primarily a feature release:
1053
1054 - a new qtype value 'mixing' has been added to the scale()
1055 method. This is faster than 'normal', slower than 'preview'. This
1056 is based on the method used by pnmscale, and seems to produce less
1057 blurry results than normal.
1058 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1059
1060 - the rubthrough() method can now render onto images with an alpha
1061 channel.
1062 http://rt.cpan.org/Ticket/Display.html?id=20678
1063
1064 - the read_multi() method now falls back to calling doing a single
1065 image read via the read() method and write_multi() will now fall
1066 back to calling write() if a single image is supplied. This means
1067 you can simply call the read_multi() or write_multi() functions
1068 without having to check if the type is formatted by that method.
1069 http://rt.cpan.org/Ticket/Display.html?id=19457
1070 http://rt.cpan.org/Ticket/Display.html?id=19458
1071
1072 - the GIF loop extension can now be written. If you don't have
1073 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1074 should upgrade.
1075 http://rt.cpan.org/Ticket/Display.html?id=21185
1076
1077 - getscanline() and setscanline() can now read/write palette index
1078 based data from/to the image for paletted images, by setting type to
1079 'index'.
1080 http://rt.cpan.org/Ticket/Display.html?id=20338
1081
1082 - we no longer hassle you to disable GIF support
1083 http://rt.cpan.org/Ticket/Display.html?id=20687
1084
1085 - minor documentation fixes
1086
1087
1088Imager 0.53 - 26 Jul 2006
1089===========
1090
1091This is a bugfix release.
1092
1093Some test code was left in a code path not covered by the test
1094suite. A test was added to cover this code path and the test code was
1095removed.
1096http://rt.cpan.org/Public/Bug/Display.html?id=20705
1097
1098
1099Imager 0.52 - 25 Jul 2006
1100===========
1101
1102This is primarily a feature release, but contains a fair few bug
1103fixes, new features:
1104
1105 - ability to read and write MS Windows ICO and CUR files
1106
1107 - you can now add file format plugins to support new file formats
1108
1109 - add POD coverage tests
1110
1111 - setcolors() and addcolors() now accept color names and so on
1112 instead of requiring Imager::Color objects.
1113 http://rt.cpan.org/Ticket/Display.html?id=20056
1114
1115 - flood_fill() can now fill to a specified border color instead of
1116 just to the area the same color as the seed.
1117 http://rt.cpan.org/Ticket/Display.html?id=19618
1118
1119
1120Bug fixes:
1121
1122 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1123 calculating the advance width.
1124 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1125
1126 - bounding_box for the T1 driver wasn't including leading and
1127 trailing spaces in the bounding box as the other drivers did, it also
1128 produced strange results for empty strings or strings containing only
1129 spaces
1130
1131 - when reading CMYK jpeg images they were being transferred to the
1132 image object as is, producing a four channel image. It only looked ok
1133 due to an old still unfixed Photoshop bug. We now convert from the
1134 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1135 http://rt.cpan.org/Ticket/Display.html?id=20416
1136
1137 - reading a CYMK TIFF would result in a 4 channel image, reading any
1138 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1139 result in an error.
1140 http://rt.cpan.org/Ticket/Display.html?id=20415
1141
1142 - added /usr/local/include to the default include search path, since
1143 we were already searching /usr/local/lib for libraries.
1144
1145And various minor fixes and documentation updates.
1146
1147
1148Imager 0.51 - 23 Apr 2006

1153 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1154
1155 - fix mis-processing of the src_maxx and src_maxy parameters of the
1156 paste() method
1157 http://rt.cpan.org/Public/Bug/Display.html?id=18712

1169 output is an in-memeory buffer.

1171
1172 - fixes an incorrect pointer parameter in the PNG code
1173 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1174
1175 - skip Inline::C tests when building in a directory with spaces
1176 http://rt.cpan.org/Public/Bug/Display.html?id=18049
