a596d4f6
TC
178 - added the ability to read multiple-image PNM files.

258==============
259
260 - further adjust the threads test so it only performs the tests on

ffddd407
TC
286 - prevent double-frees when someone creates Imager objects and then
287 creates a thread. Note: this just handles some simple cases,

295 another fill.
296

TC
297Bug fixes:
298
299 - the conv filter now enforces that the sum of the coefficients is
300 non-zero. Also, rather than skipping pixels off the edge off the
301 edge of the image, the closest edge pixel is used. Previously
302 dividing by the zero sum of coefficients could cause invalid
303 results or runtime exceptions.
304 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
305 this bug.

316 pointer dereference
317 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.
318
b3afeed5
TC
319 - an integer division meant that preview scaling to below 1 pixel
320 wide or high (which isn't too useful anyway) was calculating using
321 NaNs on most platforms, and causing an exception on others.
322 Thanks to David Cantrell for producing a backtrace of the crash on
323 his Alpha-NetBSD CPAN test box which made it possible to track this
324 down.

351 - re-work most image file test files that require a library into
352 separate library present/not present files to remove stupidly long
353 conditionals

371 - fail the read if an invalid raw_interleave parameter is supplied
372
373 - warn if no interleave or raw_interleave parameter is supplied,
374 since the documented default was wrong, and incompatible with the
375 write format

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

443 - In some cases when an error occurs reading those parts of a JPEG
444 file after the image the scan-line buffer could be freed a second
445 time. In cases where the the error occured while reading the image
446 data it's possible that the buffer could have leaked.

468 - check that the result of fileno($fh) is defined rather than simply
469 true when read() or write() is supplied with an fh parameter.

472 - i_scale_axis() wasn't checking the result of i_img_new_ch()
473 resulting in a SIGSEGV when attempting to scale an image to a size
474 too large to fit in memory. This is a NULL pointer access issue,
475 not a buffer overflow.
476 Added a check for the failure.
477 scale_calculate() (and hence scale()) will now fail if any of the
478 scale size parameters are a reference.

490This release primarily contains changes to improve ease of use -
491rather than you having to convert images to the appropriate number of
492channels, Imager handles it internally. How to handle drawing colors
493and the default combine mode is a thornier problem left for some other
494release.

499 - moved the imtoc.perl code into Imager::Preprocess
500
501 - paste() and rubthrough() now adapt the source image data to the
502 destination, so you can now safely paste/rubthrough from greyscale
503 images to color images or back, or from alpha channel images to
504 noalpha channels or back.
505 https://rt.cpan.org/Ticket/Display.html?id=30908
506
507 - rubthrough() now falls back to pasting when the source doesn't have
508 an alpha channel. This effectively treats the source as having a
509 max alpha channel, the right thing to do.
510 http://rt.cpan.org/Ticket/Display.html?id=29944
511
512 - re-worked most of the area filling code to use a common set of
513 functions when filling.
514 Corrected normal combine mode.
515 Rewrote most of the combine modes to match the way the SVG draft
516 defines them with respect to a translucent source and destination.
517 Added tests for translucent source and destination.
518 Added tests to check 8-bit/sample and double/sample combines work
519 similarly.

555 - some TGA images weren't being detected correctly as TGA images
556 https://rt.cpan.org/Ticket/Display.html?id=32925
557
558 - handling of the left-over bit for 16-bit/pixel TGA images has been
559 changed to match the behaviour of the GIMP. Previously the bit
560 being set was treated as an opaque pixel, but one user reported a
561 problem with loading such an image. I haven't been able to find any
562 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
563 I'll match it's behaviour. See issue 114913 in the GIMP's
564 bugzilla.

574 - the old dynaload code used Mach API functions to load dynamic
575 libraries on Mac OS X. These APIs have been deprecated in OS X
576 10.5 and were causing some build problems.

578 will need version 10.3 or later of OS X.

904 the file correctly
905 http://rt.cpan.org/Public/Bug/Display.html?id=22192
906

913
914 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since

930Imager 0.54 - 14 Sep 2006
931===========
932
933This is primarily a feature release:
934
935 - a new qtype value 'mixing' has been added to the scale()
936 method. This is faster than 'normal', slower than 'preview'. This
937 is based on the method used by pnmscale, and seems to produce less
938 blurry results than normal.
939 http://rt.cpan.org/Public/Bug/Display.html?id=20677
940
941 - the rubthrough() method can now render onto images with an alpha
942 channel.
943 http://rt.cpan.org/Ticket/Display.html?id=20678
944
945 - the read_multi() method now falls back to calling doing a single
946 image read via the read() method and write_multi() will now fall
947 back to calling write() if a single image is supplied. This means
948 you can simply call the read_multi() or write_multi() functions
949 without having to check if the type is formatted by that method.
950 http://rt.cpan.org/Ticket/Display.html?id=19457
951 http://rt.cpan.org/Ticket/Display.html?id=19458
952
953 - the GIF loop extension can now be written. If you don't have
954 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
955 should upgrade.
956 http://rt.cpan.org/Ticket/Display.html?id=21185
957
958 - getscanline() and setscanline() can now read/write palette index
959 based data from/to the image for paletted images, by setting type to
960 'index'.
961 http://rt.cpan.org/Ticket/Display.html?id=20338
962
963 - we no longer hassle you to disable GIF support
964 http://rt.cpan.org/Ticket/Display.html?id=20687
965
966 - minor documentation fixes
967
968
969Imager 0.53 - 26 Jul 2006
970===========
971
972This is a bugfix release.
973
974Some test code was left in a code path not covered by the test
975suite. A test was added to cover this code path and the test code was
976removed.

980Imager 0.52 - 25 Jul 2006
981===========
982
983This is primarily a feature release, but contains a fair few bug
984fixes, new features:
985
986 - ability to read and write MS Windows ICO and CUR files
987
988 - you can now add file format plugins to support new file formats
989
990 - add POD coverage tests
991
992 - setcolors() and addcolors() now accept color names and so on
993 instead of requiring Imager::Color objects.
994 http://rt.cpan.org/Ticket/Display.html?id=20056
995
996 - flood_fill() can now fill to a specified border color instead of
997 just to the area the same color as the seed.
998 http://rt.cpan.org/Ticket/Display.html?id=19618
999
1000
1001Bug fixes:
1002
1003 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1004 calculating the advance width.
1005 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1006
1007 - bounding_box for the T1 driver wasn't including leading and
1008 trailing spaces in the bounding box as the other drivers did, it also
1009 produced strange results for empty strings or strings containing only
1010 spaces
1011
1012 - when reading CMYK jpeg images they were being transferred to the
1013 image object as is, producing a four channel image. It only looked ok
1014 due to an old still unfixed Photoshop bug. We now convert from the
1015 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1016 http://rt.cpan.org/Ticket/Display.html?id=20416
1017
1018 - reading a CYMK TIFF would result in a 4 channel image, reading any
1019 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1020 result in an error.
1021 http://rt.cpan.org/Ticket/Display.html?id=20415
1022
1023 - added /usr/local/include to the default include search path, since
1024 we were already searching /usr/local/lib for libraries.
1025
1026And various minor fixes and documentation updates.
1027
