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".

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

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

264Bug fixes:
265
266 - the conv filter now enforces that the sum of the coefficients is
267 non-zero. Also, rather than skipping pixels off the edge off the
268 edge of the image, the closest edge pixel is used. Previously
269 dividing by the zero sum of coefficients could cause invalid
270 results or runtime exceptions.
271 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
272 this bug.

283 pointer dereference

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

340 - warn if no interleave or raw_interleave parameter is supplied,
341 since the documented default was wrong, and incompatible with the

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

435 - check that the result of fileno($fh) is defined rather than simply
436 true when read() or write() is supplied with an fh parameter.
437 http://rt.cpan.org/Ticket/Display.html?id=35139

439 - i_scale_axis() wasn't checking the result of i_img_new_ch()
440 resulting in a SIGSEGV when attempting to scale an image to a size
441 too large to fit in memory. This is a NULL pointer access issue,
442 not a buffer overflow.
443 Added a check for the failure.
444 scale_calculate() (and hence scale()) will now fail if any of the

457This release primarily contains changes to improve ease of use -
458rather than you having to convert images to the appropriate number of

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

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

866
867 - fills.c was failing to compile on Solaris 10 (compiler unknown)
868 http://rt.cpan.org/Public/Bug/Display.html?id=21944

870 - the gif_disposal and gif_user_input tags weren't being read from
871 the file correctly

873

877 - in some cases strings passed to the string() method were treated as
878 terminated by NUL (chr 0)
879 http://rt.cpan.org/Public/Bug/Display.html?id=21770
880
881 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
882 that's the default build name for zlib on Win32.
883 http://rt.cpan.org/Ticket/Display.html?id=23064

885 - search $Config{incpath} for headers too, which we should have been
886 doing all along.

889
890 - the global descent value from bounding box was the wrong sign
891 http://www.cpanforum.com/threads/3276
892

897Imager 0.54 - 14 Sep 2006
898===========
899
900This is primarily a feature release:
901
902 - a new qtype value 'mixing' has been added to the scale()
903 method. This is faster than 'normal', slower than 'preview'. This
904 is based on the method used by pnmscale, and seems to produce less
905 blurry results than normal.
906 http://rt.cpan.org/Public/Bug/Display.html?id=20677
907
908 - the rubthrough() method can now render onto images with an alpha
909 channel.

911
912 - the read_multi() method now falls back to calling doing a single
913 image read via the read() method and write_multi() will now fall
914 back to calling write() if a single image is supplied. This means
915 you can simply call the read_multi() or write_multi() functions
916 without having to check if the type is formatted by that method.

919
920 - the GIF loop extension can now be written. If you don't have
921 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
922 should upgrade.
923 http://rt.cpan.org/Ticket/Display.html?id=21185
924
925 - getscanline() and setscanline() can now read/write palette index
926 based data from/to the image for paletted images, by setting type to
927 'index'.
928 http://rt.cpan.org/Ticket/Display.html?id=20338
929
930 - we no longer hassle you to disable GIF support

947Imager 0.52 - 25 Jul 2006
948===========
949
950This is primarily a feature release, but contains a fair few bug
951fixes, new features:
952
953 - ability to read and write MS Windows ICO and CUR files
954
955 - you can now add file format plugins to support new file formats
956
957 - add POD coverage tests
958
959 - setcolors() and addcolors() now accept color names and so on
960 instead of requiring Imager::Color objects.
961 http://rt.cpan.org/Ticket/Display.html?id=20056
962
963 - flood_fill() can now fill to a specified border color instead of
964 just to the area the same color as the seed.
965 http://rt.cpan.org/Ticket/Display.html?id=19618
966
967
968Bug fixes:
969
970 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
971 calculating the advance width.
972 http://rt.cpan.org/Public/Bug/Display.html?id=20554
973
974 - bounding_box for the T1 driver wasn't including leading and
975 trailing spaces in the bounding box as the other drivers did, it also
976 produced strange results for empty strings or strings containing only
977 spaces
978
979 - when reading CMYK jpeg images they were being transferred to the
980 image object as is, producing a four channel image. It only looked ok
981 due to an old still unfixed Photoshop bug. We now convert from the
982 inverted CMYK that photoshop (and Corel for example) produce into RGB.
983 http://rt.cpan.org/Ticket/Display.html?id=20416
984
985 - reading a CYMK TIFF would result in a 4 channel image, reading any
986 image with more than 4 channels (eg. RGB with 2 alpha channels) would
987 result in an error.
988 http://rt.cpan.org/Ticket/Display.html?id=20415
989
990 - added /usr/local/include to the default include search path, since
991 we were already searching /usr/local/lib for libraries.
992
993And various minor fixes and documentation updates.
