15Bug fixes:
16
17 - Imager::Probe was calling ExtUtils::Liblist to initialize
18 LD_RUN_PATH supplying an undefined value rather than the found
19 directory. Thanks to Justin Davis.

45Bug fixes:
46
47 - read_types() and write_types() would include png when it wasn't

a596d4f6
TC
65 - added the ability to read multiple-image PNM files.
66 Note that unlike the pbm/pgm/ppm specification this accepts mixed
67 format files and allows white space padding between files.
68 Thanks to Philip Gwyn (Leolo) for this patch.

TC
82 - t/t50basicoo.t no longer depends on the other tests to generate its
83 input files.

TC
90 - added hardinvertall filter which also inverts the alpha channel
91 (sorry for the mess)
92
10b85929
TC

144Imager 0.71_03 - 5 Dec 2009
145==============
146
147 - further adjust the threads test so it only performs the tests on
148 perls where it's expected to work, and only if the threads module
149 can be loaded.

163 operations
164 https://rt.cpan.org/Ticket/Display.html?id=39278
165
166 - use double/sample operations to flip large sample images instead of
167 8-bit sample operations.

TC
170 - fix POD nits

172
ffddd407
TC
173 - prevent double-frees when someone creates Imager objects and then
174 creates a thread. Note: this just handles some simple cases,
175 Imager doesn't support perl threads, and isn't likely to.

181 - add the opacity fill type - an adaptor that modifies the opacity of
182 another fill.
183

TC
184Bug fixes:
185
186 - the conv filter now enforces that the sum of the coefficients is
187 non-zero. Also, rather than skipping pixels off the edge off the
188 edge of the image, the closest edge pixel is used. Previously
189 dividing by the zero sum of coefficients could cause invalid
190 results or runtime exceptions.
191 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
192 this bug.

197Bug fixes:
198
199 - release image row and comments memory on all error returns in gif
200 reader
201
202 - handle zero length extensions, previously this would cause a null
203 pointer dereference
204 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.
205

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

0d670555
TC
238 - re-work most image file test files that require a library into
239 separate library present/not present files to remove stupidly long
240 conditionals
241
242 - don't treat rubthrough() outside the bounds of the target image as
243 an error.

249Bug fixes:
250
251 - correct documentation of default of raw image interleave read
252 parameter
253 https://rt.cpan.org/Ticket/Display.html?id=42074
254
255 - add raw_ prefix to raw read parameters, though the original names
256 still work.
257
258 - fail the read if an invalid raw_interleave parameter is supplied
259
260 - warn if no interleave or raw_interleave parameter is supplied,
261 since the documented default was wrong, and incompatible with the
262 write format
263
264 - for reading raw images, if raw_storechannels > raw_datachannels,
265 set the extra channels in the image to 0
266
cd476e58
TC
267 - when probing for executables like freetype-config, search for .bat
268 and .cmd on MSWin32, as well as .exe.

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

302
5c0d0ddf
TC
303 - corrected a reference leak where writing GIFs would leak memory.
304 This could also happen calling to_paletted().
305 Also documented the underlying long existing feature where the
306 colors parameter is filled with the generated color table and added
307 tests for it.

312
c586eb58
TC
313 - add limited tests for Imager::ExtUtils
314
315 - make Imager::ExtUtils->includes use an absolute path, since

318
6b22ba84
TC
319 - re-arrange the POD for Imager::Font::BBox:
320 - mark total_width(), pos_width(), end_offset() obsolete, since
321 they're mostly for backwards compatibility
322 - group width methods and height methods

326===========
327
328Bug fixes:
329
330 - In some cases when an error occurs reading those parts of a JPEG
331 file after the image the scan-line buffer could be freed a second
332 time. In cases where the the error occured while reading the image
333 data it's possible that the buffer could have leaked.
334 Thanks to Gabriel Vasseur for reporting this and help in tracking
335 it down.

TC
347Bug fixes:

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

6912d85a 353 CVE-2008-1928
e02d22d2 354
de470892
TC
355 - check that the result of fileno($fh) is defined rather than simply
356 true when read() or write() is supplied with an fh parameter.
357 http://rt.cpan.org/Ticket/Display.html?id=35139
358
359 - i_scale_axis() wasn't checking the result of i_img_new_ch()
360 resulting in a SIGSEGV when attempting to scale an image to a size
361 too large to fit in memory. This is a NULL pointer access issue,
362 not a buffer overflow.
363 Added a check for the failure.
364 scale_calculate() (and hence scale()) will now fail if any of the
365 scale size parameters are a reference.

242d7497
TC
377This release primarily contains changes to improve ease of use -
378rather than you having to convert images to the appropriate number of
379channels, Imager handles it internally. How to handle drawing colors
380and the default combine mode is a thornier problem left for some other
381release.
382

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

385
9b1ec2b8
TC
386 - moved the imtoc.perl code into Imager::Preprocess
387
388 - paste() and rubthrough() now adapt the source image data to the
389 destination, so you can now safely paste/rubthrough from greyscale
390 images to color images or back, or from alpha channel images to
391 noalpha channels or back.
392 https://rt.cpan.org/Ticket/Display.html?id=30908
393
394 - rubthrough() now falls back to pasting when the source doesn't have
395 an alpha channel. This effectively treats the source as having a
396 max alpha channel, the right thing to do.
397 http://rt.cpan.org/Ticket/Display.html?id=29944
398
399 - re-worked most of the area filling code to use a common set of
400 functions when filling.
401 Corrected normal combine mode.
402 Rewrote most of the combine modes to match the way the SVG draft
403 defines them with respect to a translucent source and destination.
404 Added tests for translucent source and destination.
405 Added tests to check 8-bit/sample and double/sample combines work
406 similarly.

TC
430 - mixing qtype scaling now sets all channels of a pixel to zero if
431 the pixel has zero coverage (zero alpha). This should produce more
432 compressible output files.

435 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
436 Noticed when I saw:
437 https://bugzilla.redhat.com/show_bug.cgi?id=166254
438 I'm not changing the #! lines of the sample code, since it's sample
439 code, not intended for installation.

TC
442 - some TGA images weren't being detected correctly as TGA images
443 https://rt.cpan.org/Ticket/Display.html?id=32925
444
445 - handling of the left-over bit for 16-bit/pixel TGA images has been
446 changed to match the behaviour of the GIMP. Previously the bit
447 being set was treated as an opaque pixel, but one user reported a
448 problem with loading such an image. I haven't been able to find any
449 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
450 I'll match it's behaviour. See issue 114913 in the GIMP's
451 bugzilla.

461 - the old dynaload code used Mach API functions to load dynamic
462 libraries on Mac OS X. These APIs have been deprecated in OS X
463 10.5 and were causing some build problems.
464 So henceforth Imager uses the dlopen() family of functions, and you
465 will need version 10.3 or later of OS X.

772This is primarily a bug fix release.
773
774Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
775
776There is one new feature:
777
778 - the Win32 font driver now supports UTF8 (RT 22166)
779 http://www.cpanforum.com/threads/3276
780 http://rt.cpan.org/Ticket/Display.html?id=22166
781
782Several bugs were fixed:
783
784 - the string() method would not output the string "0"
785 http://rt.cpan.org/Public/Bug/Display.html?id=21770
786
787 - fills.c was failing to compile on Solaris 10 (compiler unknown)
788 http://rt.cpan.org/Public/Bug/Display.html?id=21944
789
790 - the gif_disposal and gif_user_input tags weren't being read from
791 the file correctly
792 http://rt.cpan.org/Public/Bug/Display.html?id=22192
793
794 - gif.c was failing to build under MSVC
795 http://rt.cpan.org/Ticket/Display.html?id=23922
796
797 - in some cases strings passed to the string() method were treated as
798 terminated by NUL (chr 0)
799 http://rt.cpan.org/Public/Bug/Display.html?id=21770
800
801 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
802 that's the default build name for zlib on Win32.
803 http://rt.cpan.org/Ticket/Display.html?id=23064
804
805 - search $Config{incpath} for headers too, which we should have been
806 doing all along.
807
808Win32 font driver fixes:
809
810 - the global descent value from bounding box was the wrong sign
811 http://www.cpanforum.com/threads/3276
812
813 - if the first or last glyph overflowed the left or right side of the
814 advance width they would be clipped
815
816
817Imager 0.54 - 14 Sep 2006
818===========
819
820This is primarily a feature release:
821
822 - a new qtype value 'mixing' has been added to the scale()
823 method. This is faster than 'normal', slower than 'preview'. This
824 is based on the method used by pnmscale, and seems to produce less
825 blurry results than normal.
826 http://rt.cpan.org/Public/Bug/Display.html?id=20677
827
828 - the rubthrough() method can now render onto images with an alpha
829 channel.
830 http://rt.cpan.org/Ticket/Display.html?id=20678
831
832 - the read_multi() method now falls back to calling doing a single
833 image read via the read() method and write_multi() will now fall
834 back to calling write() if a single image is supplied. This means
835 you can simply call the read_multi() or write_multi() functions
836 without having to check if the type is formatted by that method.
837 http://rt.cpan.org/Ticket/Display.html?id=19457
838 http://rt.cpan.org/Ticket/Display.html?id=19458
839
840 - the GIF loop extension can now be written. If you don't have
841 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
842 should upgrade.
843 http://rt.cpan.org/Ticket/Display.html?id=21185
844
845 - getscanline() and setscanline() can now read/write palette index
846 based data from/to the image for paletted images, by setting type to
847 'index'.
848 http://rt.cpan.org/Ticket/Display.html?id=20338
849
850 - we no longer hassle you to disable GIF support
851 http://rt.cpan.org/Ticket/Display.html?id=20687
852
853 - minor documentation fixes
854
855
856Imager 0.53 - 26 Jul 2006
857===========
858
859This is a bugfix release.
860
861Some test code was left in a code path not covered by the test
862suite. A test was added to cover this code path and the test code was
863removed.
864http://rt.cpan.org/Public/Bug/Display.html?id=20705
865
866
867Imager 0.52 - 25 Jul 2006
868===========
869
870This is primarily a feature release, but contains a fair few bug
871fixes, new features:
872
873 - ability to read and write MS Windows ICO and CUR files
874
875 - you can now add file format plugins to support new file formats
876
877 - add POD coverage tests
878
879 - setcolors() and addcolors() now accept color names and so on
880 instead of requiring Imager::Color objects.
881 http://rt.cpan.org/Ticket/Display.html?id=20056
882
883 - flood_fill() can now fill to a specified border color instead of
884 just to the area the same color as the seed.
885 http://rt.cpan.org/Ticket/Display.html?id=19618
886
887
888Bug fixes:
889
890 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
891 calculating the advance width.
892 http://rt.cpan.org/Public/Bug/Display.html?id=20554
893
894 - bounding_box for the T1 driver wasn't including leading and
895 trailing spaces in the bounding box as the other drivers did, it also
896 produced strange results for empty strings or strings containing only
897 spaces
898
899 - when reading CMYK jpeg images they were being transferred to the
900 image object as is, producing a four channel image. It only looked ok
901 due to an old still unfixed Photoshop bug. We now convert from the
902 inverted CMYK that photoshop (and Corel for example) produce into RGB.
903 http://rt.cpan.org/Ticket/Display.html?id=20416
904
905 - reading a CYMK TIFF would result in a 4 channel image, reading any
906 image with more than 4 channels (eg. RGB with 2 alpha channels) would
907 result in an error.
908 http://rt.cpan.org/Ticket/Display.html?id=20415
909
910 - added /usr/local/include to the default include search path, since
911 we were already searching /usr/local/lib for libraries.
912
913And various minor fixes and documentation updates.
914
915
916Imager 0.51 - 23 Apr 2006
