TC
41Bug fixes:
42
43 - Imager::Probe was calling ExtUtils::Liblist to initialize

50 https://rt.cpan.org/Ticket/Display.html?id=60509
51
173c91ba 52 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
53 used for color translation on Unix-like systems, and the fix
54 improves performance of supplying colors by name by about 80 times.
55 Test code that managed 3400 10x10 pixel boxes/second sped up to
56 25700 boxes/second.

a596d4f6
TC
109 - added the ability to read multiple-image PNM files.
110 Note that unlike the pbm/pgm/ppm specification this accepts mixed
111 format files and allows white space padding between files.
112 Thanks to Philip Gwyn (Leolo) for this patch.
113
1d7e3124
TC
114 - moved the PNG file handling code into a sub-module in preparation

134 - added hardinvertall filter which also inverts the alpha channel
135 (sorry for the mess)
136
10b85929
TC
137 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
138 the probe can find the library for the test run.

TC
188Imager 0.71_03 - 5 Dec 2009
189==============
190
191 - further adjust the threads test so it only performs the tests on
192 perls where it's expected to work, and only if the threads module
193 can be loaded.

202===========
203
204Bug fixes:
205
206 - use scanline oriented operations to flip images instead of pixel
207 operations
208 https://rt.cpan.org/Ticket/Display.html?id=39278
209
210 - use double/sample operations to flip large sample images instead of
211 8-bit sample operations.

213
de3ca2fd
TC
214 - fix POD nits
215 https://rt.cpan.org/Ticket/Display.html?id=51874
216
ffddd407
TC
217 - prevent double-frees when someone creates Imager objects and then
218 creates a thread. Note: this just handles some simple cases,
219 Imager doesn't support perl threads, and isn't likely to.

6a3cbaef
TC
223===========
224
a16bae72
TC
225 - add the opacity fill type - an adaptor that modifies the opacity of
226 another fill.
227
6a3cbaef
TC
228Bug fixes:
229
230 - the conv filter now enforces that the sum of the coefficients is
231 non-zero. Also, rather than skipping pixels off the edge off the
232 edge of the image, the closest edge pixel is used. Previously
233 dividing by the zero sum of coefficients could cause invalid
234 results or runtime exceptions.
235 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
236 this bug.

TC
239===========
240
241Bug fixes:
242
243 - release image row and comments memory on all error returns in gif
244 reader
245
246 - handle zero length extensions, previously this would cause a null
247 pointer dereference
248 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.
249

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

262 - broken test fix - was attempting to call a function skip_all, when
263 that should be a parameter to plan().
264
b1e29946
TC
265 - briefly document apidocs.perl, the tool used to build
266 Imager::APIRef and make some minor enhancements

0d670555
TC
282 - re-work most image file test files that require a library into
283 separate library present/not present files to remove stupidly long
284 conditionals
285
286 - don't treat rubthrough() outside the bounds of the target image as
287 an error.

295 - correct documentation of default of raw image interleave read
296 parameter
297 https://rt.cpan.org/Ticket/Display.html?id=42074
298
299 - add raw_ prefix to raw read parameters, though the original names
300 still work.
301
302 - fail the read if an invalid raw_interleave parameter is supplied
303
304 - warn if no interleave or raw_interleave parameter is supplied,
305 since the documented default was wrong, and incompatible with the
306 write format
307
308 - for reading raw images, if raw_storechannels > raw_datachannels,
309 set the extra channels in the image to 0
310
cd476e58
TC
311 - when probing for executables like freetype-config, search for .bat

TC
343 - an optimization skipping 0 src alpha values could cause the
344 rubthrough() to read past the end of a buffer.

346
5c0d0ddf
TC
347 - corrected a reference leak where writing GIFs would leak memory.
348 This could also happen calling to_paletted().
349 Also documented the underlying long existing feature where the
350 colors parameter is filled with the generated color table and added
351 tests for it.

c586eb58
TC
357 - add limited tests for Imager::ExtUtils
358
359 - make Imager::ExtUtils->includes use an absolute path, since

362
6b22ba84
TC
363 - re-arrange the POD for Imager::Font::BBox:
364 - mark total_width(), pos_width(), end_offset() obsolete, since
365 they're mostly for backwards compatibility
366 - group width methods and height methods

370===========
371
372Bug fixes:
373
374 - In some cases when an error occurs reading those parts of a JPEG
375 file after the image the scan-line buffer could be freed a second
376 time. In cases where the the error occured while reading the image
377 data it's possible that the buffer could have leaked.
378 Thanks to Gabriel Vasseur for reporting this and help in tracking
379 it down.

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

6912d85a 397 CVE-2008-1928
e02d22d2 398
de470892
TC
399 - check that the result of fileno($fh) is defined rather than simply
400 true when read() or write() is supplied with an fh parameter.
401 http://rt.cpan.org/Ticket/Display.html?id=35139
402
403 - i_scale_axis() wasn't checking the result of i_img_new_ch()
404 resulting in a SIGSEGV when attempting to scale an image to a size
405 too large to fit in memory. This is a NULL pointer access issue,
406 not a buffer overflow.
407 Added a check for the failure.
408 scale_calculate() (and hence scale()) will now fail if any of the
409 scale size parameters are a reference.

TC
421This release primarily contains changes to improve ease of use -
422rather than you having to convert images to the appropriate number of
423channels, Imager handles it internally. How to handle drawing colors
424and the default combine mode is a thornier problem left for some other
425release.
426

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

429
9b1ec2b8
TC
430 - moved the imtoc.perl code into Imager::Preprocess
431
432 - paste() and rubthrough() now adapt the source image data to the
433 destination, so you can now safely paste/rubthrough from greyscale
434 images to color images or back, or from alpha channel images to
435 noalpha channels or back.
436 https://rt.cpan.org/Ticket/Display.html?id=30908
437
438 - rubthrough() now falls back to pasting when the source doesn't have
439 an alpha channel. This effectively treats the source as having a
440 max alpha channel, the right thing to do.
441 http://rt.cpan.org/Ticket/Display.html?id=29944
442
443 - re-worked most of the area filling code to use a common set of
444 functions when filling.
445 Corrected normal combine mode.
446 Rewrote most of the combine modes to match the way the SVG draft
447 defines them with respect to a translucent source and destination.
448 Added tests for translucent source and destination.
449 Added tests to check 8-bit/sample and double/sample combines work
450 similarly.

486 - some TGA images weren't being detected correctly as TGA images
487 https://rt.cpan.org/Ticket/Display.html?id=32925
488
489 - handling of the left-over bit for 16-bit/pixel TGA images has been
490 changed to match the behaviour of the GIMP. Previously the bit
491 being set was treated as an opaque pixel, but one user reported a
492 problem with loading such an image. I haven't been able to find any
493 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
494 I'll match it's behaviour. See issue 114913 in the GIMP's
495 bugzilla.

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

823 http://www.cpanforum.com/threads/3276
824 http://rt.cpan.org/Ticket/Display.html?id=22166
825
826Several bugs were fixed:
827
828 - the string() method would not output the string "0"
829 http://rt.cpan.org/Public/Bug/Display.html?id=21770
830
831 - fills.c was failing to compile on Solaris 10 (compiler unknown)
832 http://rt.cpan.org/Public/Bug/Display.html?id=21944
833
834 - the gif_disposal and gif_user_input tags weren't being read from
835 the file correctly
836 http://rt.cpan.org/Public/Bug/Display.html?id=22192
837
838 - gif.c was failing to build under MSVC
839 http://rt.cpan.org/Ticket/Display.html?id=23922
840
841 - in some cases strings passed to the string() method were treated as
842 terminated by NUL (chr 0)
843 http://rt.cpan.org/Public/Bug/Display.html?id=21770
844
845 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
846 that's the default build name for zlib on Win32.
847 http://rt.cpan.org/Ticket/Display.html?id=23064
848
849 - search $Config{incpath} for headers too, which we should have been
850 doing all along.
851
852Win32 font driver fixes:
853
854 - the global descent value from bounding box was the wrong sign
855 http://www.cpanforum.com/threads/3276
856
857 - if the first or last glyph overflowed the left or right side of the
858 advance width they would be clipped
859
860
861Imager 0.54 - 14 Sep 2006
862===========
863
864This is primarily a feature release:
865
866 - a new qtype value 'mixing' has been added to the scale()
867 method. This is faster than 'normal', slower than 'preview'. This
868 is based on the method used by pnmscale, and seems to produce less
869 blurry results than normal.
870 http://rt.cpan.org/Public/Bug/Display.html?id=20677
871
872 - the rubthrough() method can now render onto images with an alpha
873 channel.
874 http://rt.cpan.org/Ticket/Display.html?id=20678
875
876 - the read_multi() method now falls back to calling doing a single
877 image read via the read() method and write_multi() will now fall
878 back to calling write() if a single image is supplied. This means
879 you can simply call the read_multi() or write_multi() functions
880 without having to check if the type is formatted by that method.
881 http://rt.cpan.org/Ticket/Display.html?id=19457
882 http://rt.cpan.org/Ticket/Display.html?id=19458
883
884 - the GIF loop extension can now be written. If you don't have
885 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
886 should upgrade.
887 http://rt.cpan.org/Ticket/Display.html?id=21185
888
889 - getscanline() and setscanline() can now read/write palette index
890 based data from/to the image for paletted images, by setting type to
891 'index'.
892 http://rt.cpan.org/Ticket/Display.html?id=20338
893
894 - we no longer hassle you to disable GIF support
895 http://rt.cpan.org/Ticket/Display.html?id=20687
896
897 - minor documentation fixes
898
899

902
903This is a bugfix release.

916
917 - ability to read and write MS Windows ICO and CUR files
918
919 - you can now add file format plugins to support new file formats
920
921 - add POD coverage tests
922
923 - setcolors() and addcolors() now accept color names and so on

930
931
932Bug fixes:
933
934 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
935 calculating the advance width.
936 http://rt.cpan.org/Public/Bug/Display.html?id=20554
937
938 - bounding_box for the T1 driver wasn't including leading and
939 trailing spaces in the bounding box as the other drivers did, it also
940 produced strange results for empty strings or strings containing only
941 spaces
942
943 - when reading CMYK jpeg images they were being transferred to the
944 image object as is, producing a four channel image. It only looked ok
945 due to an old still unfixed Photoshop bug. We now convert from the
946 inverted CMYK that photoshop (and Corel for example) produce into RGB.
947 http://rt.cpan.org/Ticket/Display.html?id=20416
948
949 - reading a CYMK TIFF would result in a 4 channel image, reading any
950 image with more than 4 channels (eg. RGB with 2 alpha channels) would
951 result in an error.

953
954 - added /usr/local/include to the default include search path, since
955 we were already searching /usr/local/lib for libraries.
