TC
9 - the convert() method now optimizes the case where all output
10 channels are either 0, sourced from a single input channel or 1.
11 This significantly speeds up presets like "addalpha", "green".

173c91ba 92 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
93 used for color translation on Unix-like systems, and the fix
94 improves performance of supplying colors by name by about 80 times.

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

231 - further adjust the threads test so it only performs the tests on
232 perls where it's expected to work, and only if the threads module
233 can be loaded.

256
ffddd407
TC
257 - prevent double-frees when someone creates Imager objects and then
258 creates a thread. Note: this just handles some simple cases,
259 Imager doesn't support perl threads, and isn't likely to.

TC
268Bug fixes:
269
270 - the conv filter now enforces that the sum of the coefficients is
271 non-zero. Also, rather than skipping pixels off the edge off the
272 edge of the image, the closest edge pixel is used. Previously
273 dividing by the zero sum of coefficients could cause invalid
274 results or runtime exceptions.
275 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
276 this bug.

283 - release image row and comments memory on all error returns in gif
284 reader
285

287 pointer dereference
288 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.

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

322 - re-work most image file test files that require a library into
323 separate library present/not present files to remove stupidly long
324 conditionals

338
339 - add raw_ prefix to raw read parameters, though the original names
340 still work.
341
342 - fail the read if an invalid raw_interleave parameter is supplied
343
344 - warn if no interleave or raw_interleave parameter is supplied,
345 since the documented default was wrong, and incompatible with the
346 write format
347
348 - for reading raw images, if raw_storechannels > raw_datachannels,
349 set the extra channels in the image to 0

387 - corrected a reference leak where writing GIFs would leak memory.

414 - In some cases when an error occurs reading those parts of a JPEG
415 file after the image the scan-line buffer could be freed a second
416 time. In cases where the the error occured while reading the image

e02d22d2
TC
433 - Possible security issue: The floating point sample path for image
434 based fills had a buffer overflow. This would overwrite the end of
435 a malloc()ed buffer with double precision floats.

de470892
TC
439 - check that the result of fileno($fh) is defined rather than simply
440 true when read() or write() is supplied with an fh parameter.
441 http://rt.cpan.org/Ticket/Display.html?id=35139
442
443 - i_scale_axis() wasn't checking the result of i_img_new_ch()
444 resulting in a SIGSEGV when attempting to scale an image to a size
445 too large to fit in memory. This is a NULL pointer access issue,
446 not a buffer overflow.
447 Added a check for the failure.
448 scale_calculate() (and hence scale()) will now fail if any of the
449 scale size parameters are a reference.

461This release primarily contains changes to improve ease of use -
462rather than you having to convert images to the appropriate number of
463channels, Imager handles it internally. How to handle drawing colors
464and the default combine mode is a thornier problem left for some other
465release.

470 - moved the imtoc.perl code into Imager::Preprocess

472 - paste() and rubthrough() now adapt the source image data to the
473 destination, so you can now safely paste/rubthrough from greyscale
474 images to color images or back, or from alpha channel images to
475 noalpha channels or back.
476 https://rt.cpan.org/Ticket/Display.html?id=30908
477
478 - rubthrough() now falls back to pasting when the source doesn't have
479 an alpha channel. This effectively treats the source as having a
480 max alpha channel, the right thing to do.
481 http://rt.cpan.org/Ticket/Display.html?id=29944
482
483 - re-worked most of the area filling code to use a common set of
484 functions when filling.
485 Corrected normal combine mode.
486 Rewrote most of the combine modes to match the way the SVG draft
487 defines them with respect to a translucent source and destination.
488 Added tests for translucent source and destination.
489 Added tests to check 8-bit/sample and double/sample combines work
490 similarly.

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

858Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
859
860There is one new feature:
861
862 - the Win32 font driver now supports UTF8 (RT 22166)
863 http://www.cpanforum.com/threads/3276
864 http://rt.cpan.org/Ticket/Display.html?id=22166
865
866Several bugs were fixed:
867
868 - the string() method would not output the string "0"
869 http://rt.cpan.org/Public/Bug/Display.html?id=21770
870
871 - fills.c was failing to compile on Solaris 10 (compiler unknown)
872 http://rt.cpan.org/Public/Bug/Display.html?id=21944
873
874 - the gif_disposal and gif_user_input tags weren't being read from
875 the file correctly
876 http://rt.cpan.org/Public/Bug/Display.html?id=22192
877
878 - gif.c was failing to build under MSVC
879 http://rt.cpan.org/Ticket/Display.html?id=23922
880
881 - in some cases strings passed to the string() method were treated as
882 terminated by NUL (chr 0)
883 http://rt.cpan.org/Public/Bug/Display.html?id=21770
884
885 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
886 that's the default build name for zlib on Win32.
887 http://rt.cpan.org/Ticket/Display.html?id=23064
888
889 - search $Config{incpath} for headers too, which we should have been
890 doing all along.
891
892Win32 font driver fixes:
893
894 - the global descent value from bounding box was the wrong sign
895 http://www.cpanforum.com/threads/3276
896
897 - if the first or last glyph overflowed the left or right side of the
898 advance width they would be clipped
899
900
901Imager 0.54 - 14 Sep 2006
902===========
903
904This is primarily a feature release:
905
906 - a new qtype value 'mixing' has been added to the scale()
907 method. This is faster than 'normal', slower than 'preview'. This
908 is based on the method used by pnmscale, and seems to produce less
909 blurry results than normal.
910 http://rt.cpan.org/Public/Bug/Display.html?id=20677
911
912 - the rubthrough() method can now render onto images with an alpha
913 channel.
914 http://rt.cpan.org/Ticket/Display.html?id=20678
915
916 - the read_multi() method now falls back to calling doing a single
917 image read via the read() method and write_multi() will now fall
918 back to calling write() if a single image is supplied. This means
919 you can simply call the read_multi() or write_multi() functions
920 without having to check if the type is formatted by that method.

922 http://rt.cpan.org/Ticket/Display.html?id=19458
923
924 - the GIF loop extension can now be written. If you don't have
925 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
926 should upgrade.
927 http://rt.cpan.org/Ticket/Display.html?id=21185
928
929 - getscanline() and setscanline() can now read/write palette index
930 based data from/to the image for paletted images, by setting type to
931 'index'.
932 http://rt.cpan.org/Ticket/Display.html?id=20338
933
934 - we no longer hassle you to disable GIF support

941===========
942
943This is a bugfix release.
944
945Some test code was left in a code path not covered by the test
946suite. A test was added to cover this code path and the test code was
947removed.

951Imager 0.52 - 25 Jul 2006
952===========
953
954This is primarily a feature release, but contains a fair few bug
955fixes, new features:
956
957 - ability to read and write MS Windows ICO and CUR files
958
959 - you can now add file format plugins to support new file formats
960
961 - add POD coverage tests
962
963 - setcolors() and addcolors() now accept color names and so on
964 instead of requiring Imager::Color objects.
965 http://rt.cpan.org/Ticket/Display.html?id=20056
966
967 - flood_fill() can now fill to a specified border color instead of
968 just to the area the same color as the seed.
969 http://rt.cpan.org/Ticket/Display.html?id=19618
970
971
972Bug fixes:
973
974 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
975 calculating the advance width.
976 http://rt.cpan.org/Public/Bug/Display.html?id=20554
977
978 - bounding_box for the T1 driver wasn't including leading and
979 trailing spaces in the bounding box as the other drivers did, it also
980 produced strange results for empty strings or strings containing only
981 spaces
982
983 - when reading CMYK jpeg images they were being transferred to the
984 image object as is, producing a four channel image. It only looked ok
985 due to an old still unfixed Photoshop bug. We now convert from the
986 inverted CMYK that photoshop (and Corel for example) produce into RGB.
987 http://rt.cpan.org/Ticket/Display.html?id=20416
988
989 - reading a CYMK TIFF would result in a 4 channel image, reading any
990 image with more than 4 channels (eg. RGB with 2 alpha channels) would
991 result in an error.
992 http://rt.cpan.org/Ticket/Display.html?id=20415
993
994 - added /usr/local/include to the default include search path, since
995 we were already searching /usr/local/lib for libraries.
996
997And various minor fixes and documentation updates.
