63
173c91ba 64 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
65 used for color translation on Unix-like systems, and the fix
66 improves performance of supplying colors by name by about 80 times.

121 - added the ability to read multiple-image PNM files.
122 Note that unlike the pbm/pgm/ppm specification this accepts mixed
123 format files and allows white space padding between files.

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

TC
240Bug fixes:
241
242 - the conv filter now enforces that the sum of the coefficients is
243 non-zero. Also, rather than skipping pixels off the edge off the
244 edge of the image, the closest edge pixel is used. Previously
245 dividing by the zero sum of coefficients could cause invalid
246 results or runtime exceptions.
247 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
248 this bug.

259 pointer dereference
260 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.

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

308 parameter
309 https://rt.cpan.org/Ticket/Display.html?id=42074
310
311 - add raw_ prefix to raw read parameters, though the original names
312 still work.
313
314 - fail the read if an invalid raw_interleave parameter is supplied
315
316 - warn if no interleave or raw_interleave parameter is supplied,
317 since the documented default was wrong, and incompatible with the
318 write format

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

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

TC
411 - check that the result of fileno($fh) is defined rather than simply
412 true when read() or write() is supplied with an fh parameter.
413 http://rt.cpan.org/Ticket/Display.html?id=35139
414
415 - i_scale_axis() wasn't checking the result of i_img_new_ch()
416 resulting in a SIGSEGV when attempting to scale an image to a size
417 too large to fit in memory. This is a NULL pointer access issue,
418 not a buffer overflow.
419 Added a check for the failure.
420 scale_calculate() (and hence scale()) will now fail if any of the
421 scale size parameters are a reference.

433This release primarily contains changes to improve ease of use -
434rather than you having to convert images to the appropriate number of
435channels, Imager handles it internally. How to handle drawing colors
436and the default combine mode is a thornier problem left for some other
437release.
438

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

TC
442 - moved the imtoc.perl code into Imager::Preprocess
443
444 - paste() and rubthrough() now adapt the source image data to the
445 destination, so you can now safely paste/rubthrough from greyscale
446 images to color images or back, or from alpha channel images to
447 noalpha channels or back.
448 https://rt.cpan.org/Ticket/Display.html?id=30908
449
450 - rubthrough() now falls back to pasting when the source doesn't have
451 an alpha channel. This effectively treats the source as having a
452 max alpha channel, the right thing to do.
453 http://rt.cpan.org/Ticket/Display.html?id=29944
454
455 - re-worked most of the area filling code to use a common set of
456 functions when filling.
457 Corrected normal combine mode.
458 Rewrote most of the combine modes to match the way the SVG draft
459 defines them with respect to a translucent source and destination.
460 Added tests for translucent source and destination.
461 Added tests to check 8-bit/sample and double/sample combines work
462 similarly.

465 - writing a 2 or 4 channel image to a JPEG file will now write that
466 image as if composited against a background, black by default,
467 overridable with the i_background tag/parameter.

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

830Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
831
832There is one new feature:
833
834 - the Win32 font driver now supports UTF8 (RT 22166)
835 http://www.cpanforum.com/threads/3276
836 http://rt.cpan.org/Ticket/Display.html?id=22166
837
838Several bugs were fixed:
839
840 - the string() method would not output the string "0"
841 http://rt.cpan.org/Public/Bug/Display.html?id=21770
842
843 - fills.c was failing to compile on Solaris 10 (compiler unknown)
844 http://rt.cpan.org/Public/Bug/Display.html?id=21944
845
846 - the gif_disposal and gif_user_input tags weren't being read from
847 the file correctly
848 http://rt.cpan.org/Public/Bug/Display.html?id=22192
849
850 - gif.c was failing to build under MSVC
851 http://rt.cpan.org/Ticket/Display.html?id=23922
852
853 - in some cases strings passed to the string() method were treated as
854 terminated by NUL (chr 0)
855 http://rt.cpan.org/Public/Bug/Display.html?id=21770
856
857 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
858 that's the default build name for zlib on Win32.
859 http://rt.cpan.org/Ticket/Display.html?id=23064
860
861 - search $Config{incpath} for headers too, which we should have been
862 doing all along.
863
864Win32 font driver fixes:
865
866 - the global descent value from bounding box was the wrong sign
867 http://www.cpanforum.com/threads/3276
868
869 - if the first or last glyph overflowed the left or right side of the
870 advance width they would be clipped
871
872
873Imager 0.54 - 14 Sep 2006
874===========
875
876This is primarily a feature release:
877
878 - a new qtype value 'mixing' has been added to the scale()
879 method. This is faster than 'normal', slower than 'preview'. This
880 is based on the method used by pnmscale, and seems to produce less
881 blurry results than normal.
882 http://rt.cpan.org/Public/Bug/Display.html?id=20677
883
884 - the rubthrough() method can now render onto images with an alpha
885 channel.
886 http://rt.cpan.org/Ticket/Display.html?id=20678
887
888 - the read_multi() method now falls back to calling doing a single
889 image read via the read() method and write_multi() will now fall
890 back to calling write() if a single image is supplied. This means
891 you can simply call the read_multi() or write_multi() functions
892 without having to check if the type is formatted by that method.
893 http://rt.cpan.org/Ticket/Display.html?id=19457
894 http://rt.cpan.org/Ticket/Display.html?id=19458
895
896 - the GIF loop extension can now be written. If you don't have
897 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
898 should upgrade.
899 http://rt.cpan.org/Ticket/Display.html?id=21185
900
901 - getscanline() and setscanline() can now read/write palette index
902 based data from/to the image for paletted images, by setting type to
903 'index'.
904 http://rt.cpan.org/Ticket/Display.html?id=20338
905
906 - we no longer hassle you to disable GIF support
907 http://rt.cpan.org/Ticket/Display.html?id=20687
908
909 - minor documentation fixes

923Imager 0.52 - 25 Jul 2006
924===========
925
926This is primarily a feature release, but contains a fair few bug
927fixes, new features:
928
929 - ability to read and write MS Windows ICO and CUR files
930
931 - you can now add file format plugins to support new file formats
932
933 - add POD coverage tests
934
935 - setcolors() and addcolors() now accept color names and so on
936 instead of requiring Imager::Color objects.
937 http://rt.cpan.org/Ticket/Display.html?id=20056
938
939 - flood_fill() can now fill to a specified border color instead of
940 just to the area the same color as the seed.

942
943
944Bug fixes:
945
946 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
947 calculating the advance width.
948 http://rt.cpan.org/Public/Bug/Display.html?id=20554
949
950 - bounding_box for the T1 driver wasn't including leading and
951 trailing spaces in the bounding box as the other drivers did, it also
952 produced strange results for empty strings or strings containing only
953 spaces
954
955 - when reading CMYK jpeg images they were being transferred to the
956 image object as is, producing a four channel image. It only looked ok
957 due to an old still unfixed Photoshop bug. We now convert from the
958 inverted CMYK that photoshop (and Corel for example) produce into RGB.
959 http://rt.cpan.org/Ticket/Display.html?id=20416
960
961 - reading a CYMK TIFF would result in a 4 channel image, reading any
962 image with more than 4 channels (eg. RGB with 2 alpha channels) would
963 result in an error.
964 http://rt.cpan.org/Ticket/Display.html?id=20415
965
966 - added /usr/local/include to the default include search path, since
967 we were already searching /usr/local/lib for libraries.
968
969And various minor fixes and documentation updates.
