82 https://rt.cpan.org/Ticket/Display.html?id=60509
83
173c91ba 84 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
85 used for color translation on Unix-like systems, and the fix
86 improves performance of supplying colors by name by about 80 times.
87 Test code that managed 3400 10x10 pixel boxes/second sped up to
88 25700 boxes/second.

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

167 (sorry for the mess)
168
10b85929
TC

220Imager 0.71_03 - 5 Dec 2009
221==============
222
223 - further adjust the threads test so it only performs the tests on
224 perls where it's expected to work, and only if the threads module
225 can be loaded.

239 operations
240 https://rt.cpan.org/Ticket/Display.html?id=39278
241
242 - use double/sample operations to flip large sample images instead of
243 8-bit sample operations.

248
ffddd407
TC
249 - prevent double-frees when someone creates Imager objects and then
250 creates a thread. Note: this just handles some simple cases,
251 Imager doesn't support perl threads, and isn't likely to.

257 - add the opacity fill type - an adaptor that modifies the opacity of
258 another fill.
259
6a3cbaef
TC
260Bug fixes:
261
262 - the conv filter now enforces that the sum of the coefficients is
263 non-zero. Also, rather than skipping pixels off the edge off the
264 edge of the image, the closest edge pixel is used. Previously
265 dividing by the zero sum of coefficients could cause invalid
266 results or runtime exceptions.
267 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
268 this bug.

273Bug fixes:
274
275 - release image row and comments memory on all error returns in gif
276 reader
277
278 - handle zero length extensions, previously this would cause a null
279 pointer dereference
280 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.
281

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

0d670555
TC
314 - re-work most image file test files that require a library into
315 separate library present/not present files to remove stupidly long
316 conditionals
317
318 - don't treat rubthrough() outside the bounds of the target image as
319 an error.

328 parameter
329 https://rt.cpan.org/Ticket/Display.html?id=42074
330
331 - add raw_ prefix to raw read parameters, though the original names
332 still work.
333
334 - fail the read if an invalid raw_interleave parameter is supplied
335
336 - warn if no interleave or raw_interleave parameter is supplied,
337 since the documented default was wrong, and incompatible with the
338 write format
339
340 - for reading raw images, if raw_storechannels > raw_datachannels,
341 set the extra channels in the image to 0
342
cd476e58
TC
343 - when probing for executables like freetype-config, search for .bat

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

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

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

e02d22d2 430
de470892
TC
431 - check that the result of fileno($fh) is defined rather than simply
432 true when read() or write() is supplied with an fh parameter.
433 http://rt.cpan.org/Ticket/Display.html?id=35139
434
435 - i_scale_axis() wasn't checking the result of i_img_new_ch()
436 resulting in a SIGSEGV when attempting to scale an image to a size
437 too large to fit in memory. This is a NULL pointer access issue,
438 not a buffer overflow.
439 Added a check for the failure.
440 scale_calculate() (and hence scale()) will now fail if any of the
441 scale size parameters are a reference.

TC
453This release primarily contains changes to improve ease of use -
454rather than you having to convert images to the appropriate number of
455channels, Imager handles it internally. How to handle drawing colors
456and the default combine mode is a thornier problem left for some other
457release.

TC
462 - moved the imtoc.perl code into Imager::Preprocess
463
464 - paste() and rubthrough() now adapt the source image data to the
465 destination, so you can now safely paste/rubthrough from greyscale
466 images to color images or back, or from alpha channel images to
467 noalpha channels or back.

470 - rubthrough() now falls back to pasting when the source doesn't have
471 an alpha channel. This effectively treats the source as having a
472 max alpha channel, the right thing to do.
473 http://rt.cpan.org/Ticket/Display.html?id=29944
474
475 - re-worked most of the area filling code to use a common set of
476 functions when filling.
477 Corrected normal combine mode.
478 Rewrote most of the combine modes to match the way the SVG draft
479 defines them with respect to a translucent source and destination.
480 Added tests for translucent source and destination.
481 Added tests to check 8-bit/sample and double/sample combines work
482 similarly.

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

537 - the old dynaload code used Mach API functions to load dynamic

851
852There is one new feature:

855 http://www.cpanforum.com/threads/3276
856 http://rt.cpan.org/Ticket/Display.html?id=22166

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

916 - the GIF loop extension can now be written. If you don't have
917 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
918 should upgrade.
919 http://rt.cpan.org/Ticket/Display.html?id=21185
920
921 - getscanline() and setscanline() can now read/write palette index
922 based data from/to the image for paletted images, by setting type to
923 'index'.
924 http://rt.cpan.org/Ticket/Display.html?id=20338
925
926 - we no longer hassle you to disable GIF support

933===========
934
935This is a bugfix release.

943Imager 0.52 - 25 Jul 2006
944===========
945
946This is primarily a feature release, but contains a fair few bug
947fixes, new features:
948
949 - ability to read and write MS Windows ICO and CUR files
950
951 - you can now add file format plugins to support new file formats
952
953 - add POD coverage tests
954
955 - setcolors() and addcolors() now accept color names and so on
956 instead of requiring Imager::Color objects.
957 http://rt.cpan.org/Ticket/Display.html?id=20056
958
959 - flood_fill() can now fill to a specified border color instead of
960 just to the area the same color as the seed.
961 http://rt.cpan.org/Ticket/Display.html?id=19618
962
963
964Bug fixes:
965
966 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
967 calculating the advance width.
968 http://rt.cpan.org/Public/Bug/Display.html?id=20554
969
970 - bounding_box for the T1 driver wasn't including leading and
971 trailing spaces in the bounding box as the other drivers did, it also
972 produced strange results for empty strings or strings containing only
973 spaces
974
975 - when reading CMYK jpeg images they were being transferred to the
976 image object as is, producing a four channel image. It only looked ok
977 due to an old still unfixed Photoshop bug. We now convert from the
978 inverted CMYK that photoshop (and Corel for example) produce into RGB.
979 http://rt.cpan.org/Ticket/Display.html?id=20416
980
981 - reading a CYMK TIFF would result in a 4 channel image, reading any
982 image with more than 4 channels (eg. RGB with 2 alpha channels) would
983 result in an error.
984 http://rt.cpan.org/Ticket/Display.html?id=20415
985
986 - added /usr/local/include to the default include search path, since
987 we were already searching /usr/local/lib for libraries.
988
989And various minor fixes and documentation updates.
