235 - further adjust the threads test so it only performs the tests on

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

269 - add the opacity fill type - an adaptor that modifies the opacity of
270 another fill.
271
6a3cbaef
TC
272Bug fixes:
273
274 - the conv filter now enforces that the sum of the coefficients is
275 non-zero. Also, rather than skipping pixels off the edge off the
276 edge of the image, the closest edge pixel is used. Previously
277 dividing by the zero sum of coefficients could cause invalid
278 results or runtime exceptions.
279 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
280 this bug.

291 pointer dereference
292 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.
293

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

326 - re-work most image file test files that require a library into

346 - fail the read if an invalid raw_interleave parameter is supplied
347
348 - warn if no interleave or raw_interleave parameter is supplied,
349 since the documented default was wrong, and incompatible with the

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

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

466rather than you having to convert images to the appropriate number of
467channels, Imager handles it internally. How to handle drawing colors
468and the default combine mode is a thornier problem left for some other
469release.

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

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

908This is primarily a feature release:
909
910 - a new qtype value 'mixing' has been added to the scale()
911 method. This is faster than 'normal', slower than 'preview'. This
912 is based on the method used by pnmscale, and seems to produce less
913 blurry results than normal.
914 http://rt.cpan.org/Public/Bug/Display.html?id=20677
915
916 - the rubthrough() method can now render onto images with an alpha
917 channel.
918 http://rt.cpan.org/Ticket/Display.html?id=20678
919
920 - the read_multi() method now falls back to calling doing a single
921 image read via the read() method and write_multi() will now fall
922 back to calling write() if a single image is supplied. This means
923 you can simply call the read_multi() or write_multi() functions
924 without having to check if the type is formatted by that method.
925 http://rt.cpan.org/Ticket/Display.html?id=19457
926 http://rt.cpan.org/Ticket/Display.html?id=19458
927
928 - the GIF loop extension can now be written. If you don't have
929 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
930 should upgrade.
931 http://rt.cpan.org/Ticket/Display.html?id=21185
932
933 - getscanline() and setscanline() can now read/write palette index
934 based data from/to the image for paletted images, by setting type to
935 'index'.
936 http://rt.cpan.org/Ticket/Display.html?id=20338
937
938 - we no longer hassle you to disable GIF support
939 http://rt.cpan.org/Ticket/Display.html?id=20687
940
941 - minor documentation fixes
942
943
944Imager 0.53 - 26 Jul 2006
945===========
946
947This is a bugfix release.
948
949Some test code was left in a code path not covered by the test
950suite. A test was added to cover this code path and the test code was
951removed.

953
954
955Imager 0.52 - 25 Jul 2006
956===========
957
958This is primarily a feature release, but contains a fair few bug
959fixes, new features:
960
961 - ability to read and write MS Windows ICO and CUR files
962
963 - you can now add file format plugins to support new file formats
964
965 - add POD coverage tests
966
967 - setcolors() and addcolors() now accept color names and so on
968 instead of requiring Imager::Color objects.
969 http://rt.cpan.org/Ticket/Display.html?id=20056
970
971 - flood_fill() can now fill to a specified border color instead of
972 just to the area the same color as the seed.
973 http://rt.cpan.org/Ticket/Display.html?id=19618
974
975
976Bug fixes:
977
978 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
979 calculating the advance width.
980 http://rt.cpan.org/Public/Bug/Display.html?id=20554
981
982 - bounding_box for the T1 driver wasn't including leading and
983 trailing spaces in the bounding box as the other drivers did, it also
984 produced strange results for empty strings or strings containing only
985 spaces
986
987 - when reading CMYK jpeg images they were being transferred to the
988 image object as is, producing a four channel image. It only looked ok
989 due to an old still unfixed Photoshop bug. We now convert from the
990 inverted CMYK that photoshop (and Corel for example) produce into RGB.
991 http://rt.cpan.org/Ticket/Display.html?id=20416
992
993 - reading a CYMK TIFF would result in a 4 channel image, reading any
994 image with more than 4 channels (eg. RGB with 2 alpha channels) would
995 result in an error.
996 http://rt.cpan.org/Ticket/Display.html?id=20415
997
998 - added /usr/local/include to the default include search path, since
999 we were already searching /usr/local/lib for libraries.
1000
1001And various minor fixes and documentation updates.
