82f14556
TC
152Bug fixes:
153
154 - Imager::Probe was calling ExtUtils::Liblist to initialize

161 https://rt.cpan.org/Ticket/Display.html?id=60509
162
173c91ba 163 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
164 used for color translation on Unix-like systems, and the fix
165 improves performance of supplying colors by name by about 80 times.
166 Test code that managed 3400 10x10 pixel boxes/second sped up to
167 25700 boxes/second.

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

224
1d7e3124

246 (sorry for the mess)
247

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

339Bug fixes:
340
341 - the conv filter now enforces that the sum of the coefficients is
342 non-zero. Also, rather than skipping pixels off the edge off the
343 edge of the image, the closest edge pixel is used. Previously
344 dividing by the zero sum of coefficients could cause invalid
345 results or runtime exceptions.
346 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
347 this bug.

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

510 - check that the result of fileno($fh) is defined rather than simply
511 true when read() or write() is supplied with an fh parameter.
512 http://rt.cpan.org/Ticket/Display.html?id=35139
513
514 - i_scale_axis() wasn't checking the result of i_img_new_ch()
515 resulting in a SIGSEGV when attempting to scale an image to a size
516 too large to fit in memory. This is a NULL pointer access issue,
517 not a buffer overflow.
518 Added a check for the failure.
519 scale_calculate() (and hence scale()) will now fail if any of the
520 scale size parameters are a reference.

532This release primarily contains changes to improve ease of use -
533rather than you having to convert images to the appropriate number of
534channels, Imager handles it internally. How to handle drawing colors
535and the default combine mode is a thornier problem left for some other
536release.

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

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

616 - the old dynaload code used Mach API functions to load dynamic
617 libraries on Mac OS X. These APIs have been deprecated in OS X
618 10.5 and were causing some build problems.

620 will need version 10.3 or later of OS X.

896 resulted in a memory leak.

898
899 - fix rendering on alpha channel images for the FreeType 2.x driver
900 http://rt.cpan.org/Ticket/Display.html?id=11972
901
902 - reading bmp files now consitently handles short reads. You can now
903 supply a parameter to treat a short read as successful and set
904 i_incomplete
905 http://rt.cpan.org/Ticket/Display.html?id=8426
906
907 - previously, reading ASCII PBM files required spaces between samples,
908 even though the format doesn't require that

910 - improved documentation of the unsharpmask filter (I hope)
911 http://rt.cpan.org/Ticket/Display.html?id=25531
912
913 - force flushing of the output from i_tt_dump_names() and test output
914 in t/t35ttfont.t to prevent output from being mixed up.
915 https://rt.cpan.org/Ticket/Display.html?id=24859
916
917 - rewrite a conditional expression as an if() to hopefully work around
918 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.

924Imager 0.55 - 16 Dec 2006
925===========
926
927This is primarily a bug fix release.
928
929Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
930
931There is one new feature:
932
933 - the Win32 font driver now supports UTF8 (RT 22166)
934 http://www.cpanforum.com/threads/3276
935 http://rt.cpan.org/Ticket/Display.html?id=22166
936
937Several bugs were fixed:
938
939 - the string() method would not output the string "0"
940 http://rt.cpan.org/Public/Bug/Display.html?id=21770
941
942 - fills.c was failing to compile on Solaris 10 (compiler unknown)
943 http://rt.cpan.org/Public/Bug/Display.html?id=21944
944
945 - the gif_disposal and gif_user_input tags weren't being read from
946 the file correctly
947 http://rt.cpan.org/Public/Bug/Display.html?id=22192
948
949 - gif.c was failing to build under MSVC
950 http://rt.cpan.org/Ticket/Display.html?id=23922
951
952 - in some cases strings passed to the string() method were treated as
953 terminated by NUL (chr 0)
954 http://rt.cpan.org/Public/Bug/Display.html?id=21770
955
956 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
957 that's the default build name for zlib on Win32.
958 http://rt.cpan.org/Ticket/Display.html?id=23064
959
960 - search $Config{incpath} for headers too, which we should have been
961 doing all along.
962
963Win32 font driver fixes:
964
965 - the global descent value from bounding box was the wrong sign
966 http://www.cpanforum.com/threads/3276
967
968 - if the first or last glyph overflowed the left or right side of the
969 advance width they would be clipped
970
971
972Imager 0.54 - 14 Sep 2006
973===========
974
975This is primarily a feature release:
976
977 - a new qtype value 'mixing' has been added to the scale()
978 method. This is faster than 'normal', slower than 'preview'. This
979 is based on the method used by pnmscale, and seems to produce less
980 blurry results than normal.
981 http://rt.cpan.org/Public/Bug/Display.html?id=20677
982
983 - the rubthrough() method can now render onto images with an alpha
984 channel.
985 http://rt.cpan.org/Ticket/Display.html?id=20678
986
987 - the read_multi() method now falls back to calling doing a single
988 image read via the read() method and write_multi() will now fall
989 back to calling write() if a single image is supplied. This means
990 you can simply call the read_multi() or write_multi() functions
991 without having to check if the type is formatted by that method.
992 http://rt.cpan.org/Ticket/Display.html?id=19457
993 http://rt.cpan.org/Ticket/Display.html?id=19458
994
995 - the GIF loop extension can now be written. If you don't have
996 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
997 should upgrade.
998 http://rt.cpan.org/Ticket/Display.html?id=21185
999
1000 - getscanline() and setscanline() can now read/write palette index
1001 based data from/to the image for paletted images, by setting type to
1002 'index'.
1003 http://rt.cpan.org/Ticket/Display.html?id=20338
1004
1005 - we no longer hassle you to disable GIF support
1006 http://rt.cpan.org/Ticket/Display.html?id=20687
1007
1008 - minor documentation fixes
1009
1010
1011Imager 0.53 - 26 Jul 2006
1012===========
1013
1014This is a bugfix release.
1015
1016Some test code was left in a code path not covered by the test
1017suite. A test was added to cover this code path and the test code was
1018removed.
1019http://rt.cpan.org/Public/Bug/Display.html?id=20705
1020
1021
1022Imager 0.52 - 25 Jul 2006
1023===========
1024
1025This is primarily a feature release, but contains a fair few bug
1026fixes, new features:
1027
1028 - ability to read and write MS Windows ICO and CUR files
1029
1030 - you can now add file format plugins to support new file formats
1031
1032 - add POD coverage tests
1033
1034 - setcolors() and addcolors() now accept color names and so on
1035 instead of requiring Imager::Color objects.
1036 http://rt.cpan.org/Ticket/Display.html?id=20056
1037
1038 - flood_fill() can now fill to a specified border color instead of
1039 just to the area the same color as the seed.
1040 http://rt.cpan.org/Ticket/Display.html?id=19618
1041
1042
1043Bug fixes:
1044
1045 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1046 calculating the advance width.
1047 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1048
1049 - bounding_box for the T1 driver wasn't including leading and
1050 trailing spaces in the bounding box as the other drivers did, it also
1051 produced strange results for empty strings or strings containing only
1052 spaces
1053
1054 - when reading CMYK jpeg images they were being transferred to the
1055 image object as is, producing a four channel image. It only looked ok
1056 due to an old still unfixed Photoshop bug. We now convert from the
1057 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1058 http://rt.cpan.org/Ticket/Display.html?id=20416
1059
1060 - reading a CYMK TIFF would result in a 4 channel image, reading any
1061 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1062 result in an error.
1063 http://rt.cpan.org/Ticket/Display.html?id=20415
1064
1065 - added /usr/local/include to the default include search path, since
1066 we were already searching /usr/local/lib for libraries.
1067
1068And various minor fixes and documentation updates.
1069
1070

1077
1078 - fix mis-processing of the src_maxx and src_maxy parameters of the
1079 paste() method
1080 http://rt.cpan.org/Public/Bug/Display.html?id=18712

1092 output is an in-memeory buffer.
1093 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1094
1095 - fixes an incorrect pointer parameter in the PNG code
