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

TC
225 - prevent double-frees when someone creates Imager objects and then
226 creates a thread. Note: this just handles some simple cases,
227 Imager doesn't support perl threads, and isn't likely to.

236Bug fixes:
237
238 - the conv filter now enforces that the sum of the coefficients is
239 non-zero. Also, rather than skipping pixels off the edge off the
240 edge of the image, the closest edge pixel is used. Previously
241 dividing by the zero sum of coefficients could cause invalid
242 results or runtime exceptions.
243 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
244 this bug.

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

310 - fail the read if an invalid raw_interleave parameter is supplied

312 - warn if no interleave or raw_interleave parameter is supplied,
313 since the documented default was wrong, and incompatible with the
314 write format

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

407 - check that the result of fileno($fh) is defined rather than simply
408 true when read() or write() is supplied with an fh parameter.
409 http://rt.cpan.org/Ticket/Display.html?id=35139
410
411 - i_scale_axis() wasn't checking the result of i_img_new_ch()
412 resulting in a SIGSEGV when attempting to scale an image to a size
413 too large to fit in memory. This is a NULL pointer access issue,
414 not a buffer overflow.
415 Added a check for the failure.

429This release primarily contains changes to improve ease of use -
430rather than you having to convert images to the appropriate number of
431channels, Imager handles it internally. How to handle drawing colors
432and the default combine mode is a thornier problem left for some other
433release.

435 - the font libraries are now only initialized when needed.

TC
438 - moved the imtoc.perl code into Imager::Preprocess
439
440 - paste() and rubthrough() now adapt the source image data to the
441 destination, so you can now safely paste/rubthrough from greyscale
442 images to color images or back, or from alpha channel images to
443 noalpha channels or back.
444 https://rt.cpan.org/Ticket/Display.html?id=30908
445
446 - rubthrough() now falls back to pasting when the source doesn't have
447 an alpha channel. This effectively treats the source as having a
448 max alpha channel, the right thing to do.
449 http://rt.cpan.org/Ticket/Display.html?id=29944
450
451 - re-worked most of the area filling code to use a common set of
452 functions when filling.
453 Corrected normal combine mode.
454 Rewrote most of the combine modes to match the way the SVG draft
455 defines them with respect to a translucent source and destination.
456 Added tests for translucent source and destination.
457 Added tests to check 8-bit/sample and double/sample combines work
458 similarly.

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

496
497 - handling of the left-over bit for 16-bit/pixel TGA images has been
498 changed to match the behaviour of the GIMP. Previously the bit
499 being set was treated as an opaque pixel, but one user reported a
500 problem with loading such an image. I haven't been able to find any
501 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
502 I'll match it's behaviour. See issue 114913 in the GIMP's
503 bugzilla.

513 - the old dynaload code used Mach API functions to load dynamic

826Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
827
828There is one new feature:
829
830 - the Win32 font driver now supports UTF8 (RT 22166)
831 http://www.cpanforum.com/threads/3276
832 http://rt.cpan.org/Ticket/Display.html?id=22166
833
834Several bugs were fixed:
835
836 - the string() method would not output the string "0"
837 http://rt.cpan.org/Public/Bug/Display.html?id=21770
838
839 - fills.c was failing to compile on Solaris 10 (compiler unknown)
840 http://rt.cpan.org/Public/Bug/Display.html?id=21944
841
842 - the gif_disposal and gif_user_input tags weren't being read from
843 the file correctly
844 http://rt.cpan.org/Public/Bug/Display.html?id=22192
845
846 - gif.c was failing to build under MSVC
847 http://rt.cpan.org/Ticket/Display.html?id=23922
848
849 - in some cases strings passed to the string() method were treated as
850 terminated by NUL (chr 0)
851 http://rt.cpan.org/Public/Bug/Display.html?id=21770
852
853 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
854 that's the default build name for zlib on Win32.
855 http://rt.cpan.org/Ticket/Display.html?id=23064
856
857 - search $Config{incpath} for headers too, which we should have been
858 doing all along.
859
860Win32 font driver fixes:
861
862 - the global descent value from bounding box was the wrong sign
863 http://www.cpanforum.com/threads/3276
864
865 - if the first or last glyph overflowed the left or right side of the
866 advance width they would be clipped
867
868
869Imager 0.54 - 14 Sep 2006
870===========
871
872This is primarily a feature release:
873
874 - a new qtype value 'mixing' has been added to the scale()
875 method. This is faster than 'normal', slower than 'preview'. This
876 is based on the method used by pnmscale, and seems to produce less
877 blurry results than normal.
878 http://rt.cpan.org/Public/Bug/Display.html?id=20677
879
880 - the rubthrough() method can now render onto images with an alpha
881 channel.
882 http://rt.cpan.org/Ticket/Display.html?id=20678
883
884 - the read_multi() method now falls back to calling doing a single
885 image read via the read() method and write_multi() will now fall
886 back to calling write() if a single image is supplied. This means
887 you can simply call the read_multi() or write_multi() functions
888 without having to check if the type is formatted by that method.
889 http://rt.cpan.org/Ticket/Display.html?id=19457
890 http://rt.cpan.org/Ticket/Display.html?id=19458
891
892 - the GIF loop extension can now be written. If you don't have
893 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
894 should upgrade.
895 http://rt.cpan.org/Ticket/Display.html?id=21185
896
897 - getscanline() and setscanline() can now read/write palette index
898 based data from/to the image for paletted images, by setting type to
899 'index'.
900 http://rt.cpan.org/Ticket/Display.html?id=20338
901
902 - we no longer hassle you to disable GIF support
903 http://rt.cpan.org/Ticket/Display.html?id=20687
904
905 - minor documentation fixes
906
907
908Imager 0.53 - 26 Jul 2006
909===========
910
911This is a bugfix release.
912
913Some test code was left in a code path not covered by the test
914suite. A test was added to cover this code path and the test code was

919Imager 0.52 - 25 Jul 2006
920===========
921
922This is primarily a feature release, but contains a fair few bug
923fixes, new features:
924
925 - ability to read and write MS Windows ICO and CUR files
926
927 - you can now add file format plugins to support new file formats
928
929 - add POD coverage tests
930
931 - setcolors() and addcolors() now accept color names and so on
932 instead of requiring Imager::Color objects.
933 http://rt.cpan.org/Ticket/Display.html?id=20056
934
935 - flood_fill() can now fill to a specified border color instead of
936 just to the area the same color as the seed.

938
939
940Bug fixes:
941
942 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
943 calculating the advance width.
944 http://rt.cpan.org/Public/Bug/Display.html?id=20554
945
946 - bounding_box for the T1 driver wasn't including leading and
947 trailing spaces in the bounding box as the other drivers did, it also
948 produced strange results for empty strings or strings containing only
949 spaces
950
951 - when reading CMYK jpeg images they were being transferred to the
952 image object as is, producing a four channel image. It only looked ok
953 due to an old still unfixed Photoshop bug. We now convert from the
954 inverted CMYK that photoshop (and Corel for example) produce into RGB.
955 http://rt.cpan.org/Ticket/Display.html?id=20416
956
957 - reading a CYMK TIFF would result in a 4 channel image, reading any
958 image with more than 4 channels (eg. RGB with 2 alpha channels) would
959 result in an error.
960 http://rt.cpan.org/Ticket/Display.html?id=20415
961
962 - added /usr/local/include to the default include search path, since
963 we were already searching /usr/local/lib for libraries.
964
965And various minor fixes and documentation updates.
