253 operations
254 https://rt.cpan.org/Ticket/Display.html?id=39278

256 - use double/sample operations to flip large sample images instead of
257 8-bit sample operations.

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

272 another fill.
273

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

293 pointer dereference
294 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.
295

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

328 - re-work most image file test files that require a library into
329 separate library present/not present files to remove stupidly long
330 conditionals

332 - don't treat rubthrough() outside the bounds of the target image as
333 an error.

346 still work.
347
348 - fail the read if an invalid raw_interleave parameter is supplied
349
350 - warn if no interleave or raw_interleave parameter is supplied,
351 since the documented default was wrong, and incompatible with the
352 write format

354 - for reading raw images, if raw_storechannels > raw_datachannels,
355 set the extra channels in the image to 0

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

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

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

467This release primarily contains changes to improve ease of use -
468rather than you having to convert images to the appropriate number of
469channels, Imager handles it internally. How to handle drawing colors
470and the default combine mode is a thornier problem left for some other
471release.

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

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

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

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

532 - some TGA images weren't being detected correctly as TGA images
533 https://rt.cpan.org/Ticket/Display.html?id=32925
534
535 - handling of the left-over bit for 16-bit/pixel TGA images has been
536 changed to match the behaviour of the GIMP. Previously the bit
537 being set was treated as an opaque pixel, but one user reported a
538 problem with loading such an image. I haven't been able to find any
539 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
540 I'll match it's behaviour. See issue 114913 in the GIMP's
541 bugzilla.

551 - the old dynaload code used Mach API functions to load dynamic
552 libraries on Mac OS X. These APIs have been deprecated in OS X
553 10.5 and were causing some build problems.
554 So henceforth Imager uses the dlopen() family of functions, and you
555 will need version 10.3 or later of OS X.

908===========
909
910This is primarily a feature release:
911
912 - a new qtype value 'mixing' has been added to the scale()
913 method. This is faster than 'normal', slower than 'preview'. This
914 is based on the method used by pnmscale, and seems to produce less
915 blurry results than normal.
916 http://rt.cpan.org/Public/Bug/Display.html?id=20677
917
918 - the rubthrough() method can now render onto images with an alpha
919 channel.
920 http://rt.cpan.org/Ticket/Display.html?id=20678
921
922 - the read_multi() method now falls back to calling doing a single
923 image read via the read() method and write_multi() will now fall
924 back to calling write() if a single image is supplied. This means
925 you can simply call the read_multi() or write_multi() functions
926 without having to check if the type is formatted by that method.
927 http://rt.cpan.org/Ticket/Display.html?id=19457
928 http://rt.cpan.org/Ticket/Display.html?id=19458
929
930 - the GIF loop extension can now be written. If you don't have
931 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
932 should upgrade.
933 http://rt.cpan.org/Ticket/Display.html?id=21185
934
935 - getscanline() and setscanline() can now read/write palette index
936 based data from/to the image for paletted images, by setting type to
937 'index'.
938 http://rt.cpan.org/Ticket/Display.html?id=20338
939
940 - we no longer hassle you to disable GIF support
941 http://rt.cpan.org/Ticket/Display.html?id=20687
942
943 - minor documentation fixes
944
945
946Imager 0.53 - 26 Jul 2006
947===========
948
949This is a bugfix release.
950
951Some test code was left in a code path not covered by the test
952suite. A test was added to cover this code path and the test code was
953removed.

957Imager 0.52 - 25 Jul 2006
958===========
959
960This is primarily a feature release, but contains a fair few bug
961fixes, new features:
962
963 - ability to read and write MS Windows ICO and CUR files
964
965 - you can now add file format plugins to support new file formats
966
967 - add POD coverage tests
968
969 - setcolors() and addcolors() now accept color names and so on
970 instead of requiring Imager::Color objects.
971 http://rt.cpan.org/Ticket/Display.html?id=20056
972
973 - flood_fill() can now fill to a specified border color instead of
974 just to the area the same color as the seed.
975 http://rt.cpan.org/Ticket/Display.html?id=19618
976
977
978Bug fixes:
979
980 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
981 calculating the advance width.
982 http://rt.cpan.org/Public/Bug/Display.html?id=20554
983
984 - bounding_box for the T1 driver wasn't including leading and
985 trailing spaces in the bounding box as the other drivers did, it also
986 produced strange results for empty strings or strings containing only
987 spaces
988
989 - when reading CMYK jpeg images they were being transferred to the
990 image object as is, producing a four channel image. It only looked ok
991 due to an old still unfixed Photoshop bug. We now convert from the
992 inverted CMYK that photoshop (and Corel for example) produce into RGB.
993 http://rt.cpan.org/Ticket/Display.html?id=20416
994
995 - reading a CYMK TIFF would result in a 4 channel image, reading any
996 image with more than 4 channels (eg. RGB with 2 alpha channels) would
997 result in an error.
998 http://rt.cpan.org/Ticket/Display.html?id=20415
999
1000 - added /usr/local/include to the default include search path, since
1001 we were already searching /usr/local/lib for libraries.
1002
1003And various minor fixes and documentation updates.
