309Bug fixes:
310
311 - the conv filter now enforces that the sum of the coefficients is
312 non-zero. Also, rather than skipping pixels off the edge off the
313 edge of the image, the closest edge pixel is used. Previously
314 dividing by the zero sum of coefficients could cause invalid
315 results or runtime exceptions.
316 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
317 this bug.

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

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

6912d85a 478 CVE-2008-1928
e02d22d2 479

TC
480 - check that the result of fileno($fh) is defined rather than simply
481 true when read() or write() is supplied with an fh parameter.
482 http://rt.cpan.org/Ticket/Display.html?id=35139
483
484 - i_scale_axis() wasn't checking the result of i_img_new_ch()
485 resulting in a SIGSEGV when attempting to scale an image to a size
486 too large to fit in memory. This is a NULL pointer access issue,
487 not a buffer overflow.
488 Added a check for the failure.
489 scale_calculate() (and hence scale()) will now fail if any of the
490 scale size parameters are a reference.

502This release primarily contains changes to improve ease of use -
503rather than you having to convert images to the appropriate number of
504channels, Imager handles it internally. How to handle drawing colors
505and the default combine mode is a thornier problem left for some other
506release.

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

TC
511 - moved the imtoc.perl code into Imager::Preprocess
512
513 - paste() and rubthrough() now adapt the source image data to the
514 destination, so you can now safely paste/rubthrough from greyscale
515 images to color images or back, or from alpha channel images to
516 noalpha channels or back.
517 https://rt.cpan.org/Ticket/Display.html?id=30908
518
519 - rubthrough() now falls back to pasting when the source doesn't have
520 an alpha channel. This effectively treats the source as having a
521 max alpha channel, the right thing to do.
522 http://rt.cpan.org/Ticket/Display.html?id=29944
523
524 - re-worked most of the area filling code to use a common set of
525 functions when filling.
526 Corrected normal combine mode.
527 Rewrote most of the combine modes to match the way the SVG draft
528 defines them with respect to a translucent source and destination.
529 Added tests for translucent source and destination.
530 Added tests to check 8-bit/sample and double/sample combines work
531 similarly.

TC
555 - mixing qtype scaling now sets all channels of a pixel to zero if
556 the pixel has zero coverage (zero alpha). This should produce more
557 compressible output files.

560 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
561 Noticed when I saw:
562 https://bugzilla.redhat.com/show_bug.cgi?id=166254
563 I'm not changing the #! lines of the sample code, since it's sample
564 code, not intended for installation.

TC
567 - some TGA images weren't being detected correctly as TGA images
568 https://rt.cpan.org/Ticket/Display.html?id=32925
569
570 - handling of the left-over bit for 16-bit/pixel TGA images has been
571 changed to match the behaviour of the GIMP. Previously the bit
572 being set was treated as an opaque pixel, but one user reported a
573 problem with loading such an image. I haven't been able to find any
574 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
575 I'll match it's behaviour. See issue 114913 in the GIMP's
576 bugzilla.

586 - the old dynaload code used Mach API functions to load dynamic
587 libraries on Mac OS X. These APIs have been deprecated in OS X
588 10.5 and were causing some build problems.
589 So henceforth Imager uses the dlopen() family of functions, and you
590 will need version 10.3 or later of OS X.

733 - the mask for ICO/CUR images is now applied as an alpha channel to
734 the returned image. For the old behaviour, supply ico_masked => 0

906
907Several bugs were fixed:
908
909 - the string() method would not output the string "0"
910 http://rt.cpan.org/Public/Bug/Display.html?id=21770
911
912 - fills.c was failing to compile on Solaris 10 (compiler unknown)
913 http://rt.cpan.org/Public/Bug/Display.html?id=21944
914
915 - the gif_disposal and gif_user_input tags weren't being read from
916 the file correctly
917 http://rt.cpan.org/Public/Bug/Display.html?id=22192
918
919 - gif.c was failing to build under MSVC
920 http://rt.cpan.org/Ticket/Display.html?id=23922
921
922 - in some cases strings passed to the string() method were treated as
923 terminated by NUL (chr 0)
924 http://rt.cpan.org/Public/Bug/Display.html?id=21770
925
926 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
927 that's the default build name for zlib on Win32.
928 http://rt.cpan.org/Ticket/Display.html?id=23064
929
930 - search $Config{incpath} for headers too, which we should have been
931 doing all along.

942Imager 0.54 - 14 Sep 2006
943===========
944
945This is primarily a feature release:
946
947 - a new qtype value 'mixing' has been added to the scale()
948 method. This is faster than 'normal', slower than 'preview'. This
949 is based on the method used by pnmscale, and seems to produce less
950 blurry results than normal.
951 http://rt.cpan.org/Public/Bug/Display.html?id=20677
952
953 - the rubthrough() method can now render onto images with an alpha
954 channel.
955 http://rt.cpan.org/Ticket/Display.html?id=20678
956
957 - the read_multi() method now falls back to calling doing a single
958 image read via the read() method and write_multi() will now fall
959 back to calling write() if a single image is supplied. This means
960 you can simply call the read_multi() or write_multi() functions
961 without having to check if the type is formatted by that method.
962 http://rt.cpan.org/Ticket/Display.html?id=19457
963 http://rt.cpan.org/Ticket/Display.html?id=19458
964
965 - the GIF loop extension can now be written. If you don't have
966 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
967 should upgrade.
968 http://rt.cpan.org/Ticket/Display.html?id=21185
969
970 - getscanline() and setscanline() can now read/write palette index
971 based data from/to the image for paletted images, by setting type to
972 'index'.
973 http://rt.cpan.org/Ticket/Display.html?id=20338
974
975 - we no longer hassle you to disable GIF support
976 http://rt.cpan.org/Ticket/Display.html?id=20687
977
978 - minor documentation fixes
979
980
981Imager 0.53 - 26 Jul 2006
982===========
983
984This is a bugfix release.
985
986Some test code was left in a code path not covered by the test
987suite. A test was added to cover this code path and the test code was
988removed.

991
992Imager 0.52 - 25 Jul 2006
993===========
994
995This is primarily a feature release, but contains a fair few bug
996fixes, new features:
997
998 - ability to read and write MS Windows ICO and CUR files
999
1000 - you can now add file format plugins to support new file formats
1001
1002 - add POD coverage tests
1003
1004 - setcolors() and addcolors() now accept color names and so on
1005 instead of requiring Imager::Color objects.
1006 http://rt.cpan.org/Ticket/Display.html?id=20056
1007
1008 - flood_fill() can now fill to a specified border color instead of
1009 just to the area the same color as the seed.
1010 http://rt.cpan.org/Ticket/Display.html?id=19618
1011
1012
1013Bug fixes:
1014
1015 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1016 calculating the advance width.
1017 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1018
1019 - bounding_box for the T1 driver wasn't including leading and
1020 trailing spaces in the bounding box as the other drivers did, it also
1021 produced strange results for empty strings or strings containing only
1022 spaces
1023
1024 - when reading CMYK jpeg images they were being transferred to the
1025 image object as is, producing a four channel image. It only looked ok
1026 due to an old still unfixed Photoshop bug. We now convert from the
1027 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1028 http://rt.cpan.org/Ticket/Display.html?id=20416
1029
1030 - reading a CYMK TIFF would result in a 4 channel image, reading any
1031 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1032 result in an error.
1033 http://rt.cpan.org/Ticket/Display.html?id=20415
1034
1035 - added /usr/local/include to the default include search path, since
1036 we were already searching /usr/local/lib for libraries.
1037
1038And various minor fixes and documentation updates.
1039
