47
173c91ba 48 - fix the cache check for the X rgb.txt loader. This is typically

49 used for color translation on Unix-like systems, and the fix
50 improves performance of supplying colors by name by about 80 times.

52 25700 boxes/second.

105 - added the ability to read multiple-image PNM files.
106 Note that unlike the pbm/pgm/ppm specification this accepts mixed
107 format files and allows white space padding between files.
108 Thanks to Philip Gwyn (Leolo) for this patch.

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

224Bug fixes:
225
226 - the conv filter now enforces that the sum of the coefficients is
227 non-zero. Also, rather than skipping pixels off the edge off the
228 edge of the image, the closest edge pixel is used. Previously
229 dividing by the zero sum of coefficients could cause invalid
230 results or runtime exceptions.
231 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
232 this bug.

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

301 since the documented default was wrong, and incompatible with the

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

417This release primarily contains changes to improve ease of use -
418rather than you having to convert images to the appropriate number of
419channels, Imager handles it internally. How to handle drawing colors
420and the default combine mode is a thornier problem left for some other
421release.

TC
426 - moved the imtoc.perl code into Imager::Preprocess
427
428 - paste() and rubthrough() now adapt the source image data to the
429 destination, so you can now safely paste/rubthrough from greyscale
430 images to color images or back, or from alpha channel images to
431 noalpha channels or back.
432 https://rt.cpan.org/Ticket/Display.html?id=30908
433
434 - rubthrough() now falls back to pasting when the source doesn't have
435 an alpha channel. This effectively treats the source as having a
436 max alpha channel, the right thing to do.
437 http://rt.cpan.org/Ticket/Display.html?id=29944
438
439 - re-worked most of the area filling code to use a common set of
440 functions when filling.
441 Corrected normal combine mode.
442 Rewrote most of the combine modes to match the way the SVG draft
443 defines them with respect to a translucent source and destination.
444 Added tests for translucent source and destination.
445 Added tests to check 8-bit/sample and double/sample combines work
446 similarly.

482 - some TGA images weren't being detected correctly as TGA images
483 https://rt.cpan.org/Ticket/Display.html?id=32925
484
485 - handling of the left-over bit for 16-bit/pixel TGA images has been
486 changed to match the behaviour of the GIMP. Previously the bit
487 being set was treated as an opaque pixel, but one user reported a
488 problem with loading such an image. I haven't been able to find any
489 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
490 I'll match it's behaviour. See issue 114913 in the GIMP's
491 bugzilla.

501 - the old dynaload code used Mach API functions to load dynamic
502 libraries on Mac OS X. These APIs have been deprecated in OS X
503 10.5 and were causing some build problems.

505 will need version 10.3 or later of OS X.

814Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
815
816There is one new feature:
817

819 http://www.cpanforum.com/threads/3276
820 http://rt.cpan.org/Ticket/Display.html?id=22166
821
822Several bugs were fixed:
823
824 - the string() method would not output the string "0"
825 http://rt.cpan.org/Public/Bug/Display.html?id=21770
826
827 - fills.c was failing to compile on Solaris 10 (compiler unknown)
828 http://rt.cpan.org/Public/Bug/Display.html?id=21944
829
830 - the gif_disposal and gif_user_input tags weren't being read from
831 the file correctly
832 http://rt.cpan.org/Public/Bug/Display.html?id=22192
833
834 - gif.c was failing to build under MSVC
835 http://rt.cpan.org/Ticket/Display.html?id=23922
836
837 - in some cases strings passed to the string() method were treated as
838 terminated by NUL (chr 0)
839 http://rt.cpan.org/Public/Bug/Display.html?id=21770
840
841 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
842 that's the default build name for zlib on Win32.
843 http://rt.cpan.org/Ticket/Display.html?id=23064
844
845 - search $Config{incpath} for headers too, which we should have been
846 doing all along.
847
848Win32 font driver fixes:
849
850 - the global descent value from bounding box was the wrong sign
851 http://www.cpanforum.com/threads/3276
852

854 advance width they would be clipped
855
856
857Imager 0.54 - 14 Sep 2006
858===========
859
860This is primarily a feature release:
861
862 - a new qtype value 'mixing' has been added to the scale()
863 method. This is faster than 'normal', slower than 'preview'. This
864 is based on the method used by pnmscale, and seems to produce less
865 blurry results than normal.
866 http://rt.cpan.org/Public/Bug/Display.html?id=20677
867
868 - the rubthrough() method can now render onto images with an alpha
869 channel.
870 http://rt.cpan.org/Ticket/Display.html?id=20678
871
872 - the read_multi() method now falls back to calling doing a single
873 image read via the read() method and write_multi() will now fall
874 back to calling write() if a single image is supplied. This means
875 you can simply call the read_multi() or write_multi() functions
876 without having to check if the type is formatted by that method.
877 http://rt.cpan.org/Ticket/Display.html?id=19457
878 http://rt.cpan.org/Ticket/Display.html?id=19458
879
880 - the GIF loop extension can now be written. If you don't have
881 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
882 should upgrade.
883 http://rt.cpan.org/Ticket/Display.html?id=21185
884
885 - getscanline() and setscanline() can now read/write palette index
886 based data from/to the image for paletted images, by setting type to
887 'index'.
888 http://rt.cpan.org/Ticket/Display.html?id=20338
889
890 - we no longer hassle you to disable GIF support
891 http://rt.cpan.org/Ticket/Display.html?id=20687
892
893 - minor documentation fixes
894
895
896Imager 0.53 - 26 Jul 2006
897===========
898
899This is a bugfix release.
900
901Some test code was left in a code path not covered by the test
902suite. A test was added to cover this code path and the test code was
903removed.

907Imager 0.52 - 25 Jul 2006
908===========

910This is primarily a feature release, but contains a fair few bug
911fixes, new features:

913 - ability to read and write MS Windows ICO and CUR files
914
915 - you can now add file format plugins to support new file formats
916
917 - add POD coverage tests
918
919 - setcolors() and addcolors() now accept color names and so on
920 instead of requiring Imager::Color objects.

928Bug fixes:
929
930 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
931 calculating the advance width.
932 http://rt.cpan.org/Public/Bug/Display.html?id=20554
933
934 - bounding_box for the T1 driver wasn't including leading and
935 trailing spaces in the bounding box as the other drivers did, it also
936 produced strange results for empty strings or strings containing only
937 spaces
938
939 - when reading CMYK jpeg images they were being transferred to the
940 image object as is, producing a four channel image. It only looked ok
941 due to an old still unfixed Photoshop bug. We now convert from the
942 inverted CMYK that photoshop (and Corel for example) produce into RGB.

944
945 - reading a CYMK TIFF would result in a 4 channel image, reading any
946 image with more than 4 channels (eg. RGB with 2 alpha channels) would
947 result in an error.

949
950 - added /usr/local/include to the default include search path, since
951 we were already searching /usr/local/lib for libraries.
952
953And various minor fixes and documentation updates.
