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

149 - added hardinvertall filter which also inverts the alpha channel
150 (sorry for the mess)
151
10b85929

203Imager 0.71_03 - 5 Dec 2009
204==============
205
206 - further adjust the threads test so it only performs the tests on
207 perls where it's expected to work, and only if the threads module
208 can be loaded.

222 operations
223 https://rt.cpan.org/Ticket/Display.html?id=39278
224
225 - use double/sample operations to flip large sample images instead of
226 8-bit sample operations.

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

240 - add the opacity fill type - an adaptor that modifies the opacity of
241 another fill.
242

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

256Bug fixes:
257
258 - release image row and comments memory on all error returns in gif
259 reader
260
261 - handle zero length extensions, previously this would cause a null
262 pointer dereference
263 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.
264

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

TC
297 - re-work most image file test files that require a library into
298 separate library present/not present files to remove stupidly long
299 conditionals

310 - correct documentation of default of raw image interleave read
311 parameter
312 https://rt.cpan.org/Ticket/Display.html?id=42074
313
314 - add raw_ prefix to raw read parameters, though the original names
315 still work.
316
317 - fail the read if an invalid raw_interleave parameter is supplied
318
319 - warn if no interleave or raw_interleave parameter is supplied,
320 since the documented default was wrong, and incompatible with the
321 write format
322
323 - for reading raw images, if raw_storechannels > raw_datachannels,
324 set the extra channels in the image to 0
325

TC
362 - corrected a reference leak where writing GIFs would leak memory.
363 This could also happen calling to_paletted().
364 Also documented the underlying long existing feature where the
365 colors parameter is filled with the generated color table and added
366 tests for it.

387Bug fixes:

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

394 it down.

e02d22d2
TC
408 - Possible security issue: The floating point sample path for image
409 based fills had a buffer overflow. This would overwrite the end of
410 a malloc()ed buffer with double precision floats.

e02d22d2 413
de470892
TC
414 - check that the result of fileno($fh) is defined rather than simply
415 true when read() or write() is supplied with an fh parameter.
416 http://rt.cpan.org/Ticket/Display.html?id=35139
417
418 - i_scale_axis() wasn't checking the result of i_img_new_ch()
419 resulting in a SIGSEGV when attempting to scale an image to a size
420 too large to fit in memory. This is a NULL pointer access issue,
421 not a buffer overflow.
422 Added a check for the failure.
423 scale_calculate() (and hence scale()) will now fail if any of the
424 scale size parameters are a reference.

TC
436This release primarily contains changes to improve ease of use -
437rather than you having to convert images to the appropriate number of
438channels, Imager handles it internally. How to handle drawing colors
439and the default combine mode is a thornier problem left for some other
440release.
441

TC
442 - the font libraries are now only initialized when needed.

444
9b1ec2b8
TC
445 - moved the imtoc.perl code into Imager::Preprocess
446
447 - paste() and rubthrough() now adapt the source image data to the
448 destination, so you can now safely paste/rubthrough from greyscale
449 images to color images or back, or from alpha channel images to
450 noalpha channels or back.
451 https://rt.cpan.org/Ticket/Display.html?id=30908
452
453 - rubthrough() now falls back to pasting when the source doesn't have
454 an alpha channel. This effectively treats the source as having a
455 max alpha channel, the right thing to do.
456 http://rt.cpan.org/Ticket/Display.html?id=29944
457
458 - re-worked most of the area filling code to use a common set of
459 functions when filling.
460 Corrected normal combine mode.
461 Rewrote most of the combine modes to match the way the SVG draft
462 defines them with respect to a translucent source and destination.
463 Added tests for translucent source and destination.
464 Added tests to check 8-bit/sample and double/sample combines work
465 similarly.

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

839 http://rt.cpan.org/Ticket/Display.html?id=22166

842
843 - the string() method would not output the string "0"
844 http://rt.cpan.org/Public/Bug/Display.html?id=21770
845
846 - fills.c was failing to compile on Solaris 10 (compiler unknown)
847 http://rt.cpan.org/Public/Bug/Display.html?id=21944
848
849 - the gif_disposal and gif_user_input tags weren't being read from
850 the file correctly
851 http://rt.cpan.org/Public/Bug/Display.html?id=22192
852
853 - gif.c was failing to build under MSVC
854 http://rt.cpan.org/Ticket/Display.html?id=23922
855
856 - in some cases strings passed to the string() method were treated as
857 terminated by NUL (chr 0)
858 http://rt.cpan.org/Public/Bug/Display.html?id=21770
859
860 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
861 that's the default build name for zlib on Win32.
862 http://rt.cpan.org/Ticket/Display.html?id=23064
863
864 - search $Config{incpath} for headers too, which we should have been
865 doing all along.
866
867Win32 font driver fixes:
868
869 - the global descent value from bounding box was the wrong sign
870 http://www.cpanforum.com/threads/3276
871
872 - if the first or last glyph overflowed the left or right side of the
873 advance width they would be clipped
874
875
876Imager 0.54 - 14 Sep 2006
877===========
878
879This is primarily a feature release:
880
881 - a new qtype value 'mixing' has been added to the scale()
882 method. This is faster than 'normal', slower than 'preview'. This
883 is based on the method used by pnmscale, and seems to produce less
884 blurry results than normal.
885 http://rt.cpan.org/Public/Bug/Display.html?id=20677
886
887 - the rubthrough() method can now render onto images with an alpha
888 channel.
889 http://rt.cpan.org/Ticket/Display.html?id=20678
890
891 - the read_multi() method now falls back to calling doing a single
892 image read via the read() method and write_multi() will now fall
893 back to calling write() if a single image is supplied. This means
894 you can simply call the read_multi() or write_multi() functions
895 without having to check if the type is formatted by that method.
896 http://rt.cpan.org/Ticket/Display.html?id=19457
897 http://rt.cpan.org/Ticket/Display.html?id=19458
898
899 - the GIF loop extension can now be written. If you don't have
900 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
901 should upgrade.
902 http://rt.cpan.org/Ticket/Display.html?id=21185
903
904 - getscanline() and setscanline() can now read/write palette index
905 based data from/to the image for paletted images, by setting type to
906 'index'.
907 http://rt.cpan.org/Ticket/Display.html?id=20338

926Imager 0.52 - 25 Jul 2006
927===========
928
929This is primarily a feature release, but contains a fair few bug
930fixes, new features:
931
932 - ability to read and write MS Windows ICO and CUR files
933
934 - you can now add file format plugins to support new file formats
935
936 - add POD coverage tests
937
938 - setcolors() and addcolors() now accept color names and so on
939 instead of requiring Imager::Color objects.
940 http://rt.cpan.org/Ticket/Display.html?id=20056
941
942 - flood_fill() can now fill to a specified border color instead of
943 just to the area the same color as the seed.
944 http://rt.cpan.org/Ticket/Display.html?id=19618
945
946
947Bug fixes:
948
949 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
950 calculating the advance width.
951 http://rt.cpan.org/Public/Bug/Display.html?id=20554
952
953 - bounding_box for the T1 driver wasn't including leading and
954 trailing spaces in the bounding box as the other drivers did, it also
955 produced strange results for empty strings or strings containing only
956 spaces
957
958 - when reading CMYK jpeg images they were being transferred to the
959 image object as is, producing a four channel image. It only looked ok
960 due to an old still unfixed Photoshop bug. We now convert from the
961 inverted CMYK that photoshop (and Corel for example) produce into RGB.
962 http://rt.cpan.org/Ticket/Display.html?id=20416
963
964 - reading a CYMK TIFF would result in a 4 channel image, reading any
965 image with more than 4 channels (eg. RGB with 2 alpha channels) would
966 result in an error.
967 http://rt.cpan.org/Ticket/Display.html?id=20415
968
969 - added /usr/local/include to the default include search path, since
970 we were already searching /usr/local/lib for libraries.
971
972And various minor fixes and documentation updates.
