a596d4f6
TC
164 - added the ability to read multiple-image PNM files.
165 Note that unlike the pbm/pgm/ppm specification this accepts mixed

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

262 operations

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

281 another fill.

TC
283Bug fixes:
284
285 - the conv filter now enforces that the sum of the coefficients is
286 non-zero. Also, rather than skipping pixels off the edge off the
287 edge of the image, the closest edge pixel is used. Previously
288 dividing by the zero sum of coefficients could cause invalid
289 results or runtime exceptions.
290 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
291 this bug.

302 pointer dereference
303 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.

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

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

355 still work.
356
357 - fail the read if an invalid raw_interleave parameter is supplied
358
359 - warn if no interleave or raw_interleave parameter is supplied,
360 since the documented default was wrong, and incompatible with the
361 write format

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

430 file after the image the scan-line buffer could be freed a second
431 time. In cases where the the error occured while reading the image

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

454 - check that the result of fileno($fh) is defined rather than simply
455 true when read() or write() is supplied with an fh parameter.
456 http://rt.cpan.org/Ticket/Display.html?id=35139
457
458 - i_scale_axis() wasn't checking the result of i_img_new_ch()
459 resulting in a SIGSEGV when attempting to scale an image to a size
460 too large to fit in memory. This is a NULL pointer access issue,
461 not a buffer overflow.
462 Added a check for the failure.
463 scale_calculate() (and hence scale()) will now fail if any of the
464 scale size parameters are a reference.

476This release primarily contains changes to improve ease of use -
477rather than you having to convert images to the appropriate number of
478channels, Imager handles it internally. How to handle drawing colors
479and the default combine mode is a thornier problem left for some other
480release.

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

TC
485 - moved the imtoc.perl code into Imager::Preprocess
486
487 - paste() and rubthrough() now adapt the source image data to the
488 destination, so you can now safely paste/rubthrough from greyscale
489 images to color images or back, or from alpha channel images to
490 noalpha channels or back.
491 https://rt.cpan.org/Ticket/Display.html?id=30908
492
493 - rubthrough() now falls back to pasting when the source doesn't have
494 an alpha channel. This effectively treats the source as having a
495 max alpha channel, the right thing to do.
496 http://rt.cpan.org/Ticket/Display.html?id=29944
497
498 - re-worked most of the area filling code to use a common set of
499 functions when filling.
500 Corrected normal combine mode.
501 Rewrote most of the combine modes to match the way the SVG draft
502 defines them with respect to a translucent source and destination.
503 Added tests for translucent source and destination.
504 Added tests to check 8-bit/sample and double/sample combines work
505 similarly.

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

537 I'm not changing the #! lines of the sample code, since it's sample

541 - some TGA images weren't being detected correctly as TGA images
542 https://rt.cpan.org/Ticket/Display.html?id=32925
543
544 - handling of the left-over bit for 16-bit/pixel TGA images has been
545 changed to match the behaviour of the GIMP. Previously the bit
546 being set was treated as an opaque pixel, but one user reported a
547 problem with loading such an image. I haven't been able to find any
548 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
549 I'll match it's behaviour. See issue 114913 in the GIMP's
550 bugzilla.

560 - the old dynaload code used Mach API functions to load dynamic
561 libraries on Mac OS X. These APIs have been deprecated in OS X
562 10.5 and were causing some build problems.
563 So henceforth Imager uses the dlopen() family of functions, and you
564 will need version 10.3 or later of OS X.

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

916Imager 0.54 - 14 Sep 2006
917===========
918
919This is primarily a feature release:
920
921 - a new qtype value 'mixing' has been added to the scale()
922 method. This is faster than 'normal', slower than 'preview'. This
923 is based on the method used by pnmscale, and seems to produce less
924 blurry results than normal.
925 http://rt.cpan.org/Public/Bug/Display.html?id=20677
926
927 - the rubthrough() method can now render onto images with an alpha
928 channel.
929 http://rt.cpan.org/Ticket/Display.html?id=20678
930
931 - the read_multi() method now falls back to calling doing a single
932 image read via the read() method and write_multi() will now fall
933 back to calling write() if a single image is supplied. This means
934 you can simply call the read_multi() or write_multi() functions
935 without having to check if the type is formatted by that method.
936 http://rt.cpan.org/Ticket/Display.html?id=19457
937 http://rt.cpan.org/Ticket/Display.html?id=19458
938
939 - the GIF loop extension can now be written. If you don't have
940 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
941 should upgrade.
942 http://rt.cpan.org/Ticket/Display.html?id=21185
943
944 - getscanline() and setscanline() can now read/write palette index
945 based data from/to the image for paletted images, by setting type to
946 'index'.
947 http://rt.cpan.org/Ticket/Display.html?id=20338
948
949 - we no longer hassle you to disable GIF support
950 http://rt.cpan.org/Ticket/Display.html?id=20687
951
952 - minor documentation fixes
953
954
955Imager 0.53 - 26 Jul 2006
956===========
957
958This is a bugfix release.
959
960Some test code was left in a code path not covered by the test
961suite. A test was added to cover this code path and the test code was
962removed.

965
966Imager 0.52 - 25 Jul 2006
967===========
968
969This is primarily a feature release, but contains a fair few bug
970fixes, new features:
971
972 - ability to read and write MS Windows ICO and CUR files
973
974 - you can now add file format plugins to support new file formats
975
976 - add POD coverage tests
977
978 - setcolors() and addcolors() now accept color names and so on
979 instead of requiring Imager::Color objects.
980 http://rt.cpan.org/Ticket/Display.html?id=20056
981
982 - flood_fill() can now fill to a specified border color instead of
983 just to the area the same color as the seed.
984 http://rt.cpan.org/Ticket/Display.html?id=19618
985
986
987Bug fixes:
988
989 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
990 calculating the advance width.
991 http://rt.cpan.org/Public/Bug/Display.html?id=20554
992
993 - bounding_box for the T1 driver wasn't including leading and
994 trailing spaces in the bounding box as the other drivers did, it also
995 produced strange results for empty strings or strings containing only
996 spaces
997
998 - when reading CMYK jpeg images they were being transferred to the
999 image object as is, producing a four channel image. It only looked ok
1000 due to an old still unfixed Photoshop bug. We now convert from the
1001 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1002 http://rt.cpan.org/Ticket/Display.html?id=20416
1003
1004 - reading a CYMK TIFF would result in a 4 channel image, reading any
1005 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1006 result in an error.
1007 http://rt.cpan.org/Ticket/Display.html?id=20415
1008
1009 - added /usr/local/include to the default include search path, since
1010 we were already searching /usr/local/lib for libraries.
1011
1012And various minor fixes and documentation updates.
