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

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

TC
119Bug fixes:
120
121 - the conv filter now enforces that the sum of the coefficients is
122 non-zero. Also, rather than skipping pixels off the edge off the
123 edge of the image, the closest edge pixel is used. Previously
124 dividing by the zero sum of coefficients could cause invalid
125 results or runtime exceptions.
126 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
127 this bug.

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

191 still work.
192
193 - fail the read if an invalid raw_interleave parameter is supplied
194
195 - warn if no interleave or raw_interleave parameter is supplied,
196 since the documented default was wrong, and incompatible with the
197 write format

263Bug fixes:

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

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

e02d22d2 289
de470892
TC
290 - check that the result of fileno($fh) is defined rather than simply
291 true when read() or write() is supplied with an fh parameter.
292 http://rt.cpan.org/Ticket/Display.html?id=35139
293
294 - i_scale_axis() wasn't checking the result of i_img_new_ch()
295 resulting in a SIGSEGV when attempting to scale an image to a size
296 too large to fit in memory. This is a NULL pointer access issue,
297 not a buffer overflow.
298 Added a check for the failure.
299 scale_calculate() (and hence scale()) will now fail if any of the
300 scale size parameters are a reference.

TC
312This release primarily contains changes to improve ease of use -
313rather than you having to convert images to the appropriate number of
314channels, Imager handles it internally. How to handle drawing colors
315and the default combine mode is a thornier problem left for some other
316release.
317

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

TC
321 - moved the imtoc.perl code into Imager::Preprocess
322
323 - paste() and rubthrough() now adapt the source image data to the
324 destination, so you can now safely paste/rubthrough from greyscale
325 images to color images or back, or from alpha channel images to
326 noalpha channels or back.
327 https://rt.cpan.org/Ticket/Display.html?id=30908
328
329 - rubthrough() now falls back to pasting when the source doesn't have
330 an alpha channel. This effectively treats the source as having a
331 max alpha channel, the right thing to do.
332 http://rt.cpan.org/Ticket/Display.html?id=29944
333
334 - re-worked most of the area filling code to use a common set of
335 functions when filling.
336 Corrected normal combine mode.
337 Rewrote most of the combine modes to match the way the SVG draft
338 defines them with respect to a translucent source and destination.
339 Added tests for translucent source and destination.
340 Added tests to check 8-bit/sample and double/sample combines work
341 similarly.

365 - mixing qtype scaling now sets all channels of a pixel to zero if

377 - some TGA images weren't being detected correctly as TGA images
378 https://rt.cpan.org/Ticket/Display.html?id=32925
379
380 - handling of the left-over bit for 16-bit/pixel TGA images has been
381 changed to match the behaviour of the GIMP. Previously the bit
382 being set was treated as an opaque pixel, but one user reported a
383 problem with loading such an image. I haven't been able to find any
384 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
385 I'll match it's behaviour. See issue 114913 in the GIMP's
386 bugzilla.

396 - the old dynaload code used Mach API functions to load dynamic
397 libraries on Mac OS X. These APIs have been deprecated in OS X
398 10.5 and were causing some build problems.
399 So henceforth Imager uses the dlopen() family of functions, and you
400 will need version 10.3 or later of OS X.

543 - the mask for ICO/CUR images is now applied as an alpha channel to
544 the returned image. For the old behaviour, supply ico_masked => 0

704Imager 0.55 - 16 Dec 2006
705===========
706
707This is primarily a bug fix release.
708
709Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
710
711There is one new feature:
712
713 - the Win32 font driver now supports UTF8 (RT 22166)
714 http://www.cpanforum.com/threads/3276
715 http://rt.cpan.org/Ticket/Display.html?id=22166
716
717Several bugs were fixed:
718
719 - the string() method would not output the string "0"
720 http://rt.cpan.org/Public/Bug/Display.html?id=21770
721
722 - fills.c was failing to compile on Solaris 10 (compiler unknown)
723 http://rt.cpan.org/Public/Bug/Display.html?id=21944
724
725 - the gif_disposal and gif_user_input tags weren't being read from
726 the file correctly
727 http://rt.cpan.org/Public/Bug/Display.html?id=22192
728
729 - gif.c was failing to build under MSVC
730 http://rt.cpan.org/Ticket/Display.html?id=23922
731
732 - in some cases strings passed to the string() method were treated as
733 terminated by NUL (chr 0)
734 http://rt.cpan.org/Public/Bug/Display.html?id=21770
735
736 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
737 that's the default build name for zlib on Win32.
738 http://rt.cpan.org/Ticket/Display.html?id=23064
739
740 - search $Config{incpath} for headers too, which we should have been
741 doing all along.
742
743Win32 font driver fixes:
744
745 - the global descent value from bounding box was the wrong sign
746 http://www.cpanforum.com/threads/3276
747
748 - if the first or last glyph overflowed the left or right side of the
749 advance width they would be clipped
750
751
752Imager 0.54 - 14 Sep 2006
753===========
754
755This is primarily a feature release:
756
757 - a new qtype value 'mixing' has been added to the scale()
758 method. This is faster than 'normal', slower than 'preview'. This
759 is based on the method used by pnmscale, and seems to produce less
760 blurry results than normal.
761 http://rt.cpan.org/Public/Bug/Display.html?id=20677
762
763 - the rubthrough() method can now render onto images with an alpha
764 channel.
765 http://rt.cpan.org/Ticket/Display.html?id=20678
766
767 - the read_multi() method now falls back to calling doing a single
768 image read via the read() method and write_multi() will now fall
769 back to calling write() if a single image is supplied. This means
770 you can simply call the read_multi() or write_multi() functions
771 without having to check if the type is formatted by that method.
772 http://rt.cpan.org/Ticket/Display.html?id=19457
773 http://rt.cpan.org/Ticket/Display.html?id=19458
774
775 - the GIF loop extension can now be written. If you don't have
776 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
777 should upgrade.
778 http://rt.cpan.org/Ticket/Display.html?id=21185
779
780 - getscanline() and setscanline() can now read/write palette index
781 based data from/to the image for paletted images, by setting type to
782 'index'.
783 http://rt.cpan.org/Ticket/Display.html?id=20338
784
785 - we no longer hassle you to disable GIF support
786 http://rt.cpan.org/Ticket/Display.html?id=20687
787
788 - minor documentation fixes
789
790
791Imager 0.53 - 26 Jul 2006
792===========
793
794This is a bugfix release.
795
796Some test code was left in a code path not covered by the test
797suite. A test was added to cover this code path and the test code was
798removed.
799http://rt.cpan.org/Public/Bug/Display.html?id=20705
800
801
802Imager 0.52 - 25 Jul 2006
803===========
804
805This is primarily a feature release, but contains a fair few bug
806fixes, new features:
807
808 - ability to read and write MS Windows ICO and CUR files
809
810 - you can now add file format plugins to support new file formats
811
812 - add POD coverage tests
813
814 - setcolors() and addcolors() now accept color names and so on
815 instead of requiring Imager::Color objects.
816 http://rt.cpan.org/Ticket/Display.html?id=20056
817
818 - flood_fill() can now fill to a specified border color instead of
819 just to the area the same color as the seed.
820 http://rt.cpan.org/Ticket/Display.html?id=19618
821
822
823Bug fixes:
824
825 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
826 calculating the advance width.
827 http://rt.cpan.org/Public/Bug/Display.html?id=20554
828
829 - bounding_box for the T1 driver wasn't including leading and
830 trailing spaces in the bounding box as the other drivers did, it also
831 produced strange results for empty strings or strings containing only
832 spaces
833
834 - when reading CMYK jpeg images they were being transferred to the
835 image object as is, producing a four channel image. It only looked ok
836 due to an old still unfixed Photoshop bug. We now convert from the
837 inverted CMYK that photoshop (and Corel for example) produce into RGB.
838 http://rt.cpan.org/Ticket/Display.html?id=20416
839
840 - reading a CYMK TIFF would result in a 4 channel image, reading any
841 image with more than 4 channels (eg. RGB with 2 alpha channels) would
842 result in an error.
843 http://rt.cpan.org/Ticket/Display.html?id=20415
844
845 - added /usr/local/include to the default include search path, since
846 we were already searching /usr/local/lib for libraries.
847
848And various minor fixes and documentation updates.
849
850
851Imager 0.51 - 23 Apr 2006

857

871 or 4 channel image to jpeg or a 2 channel image to tga where the
872 output is an in-memeory buffer.
873 http://rt.cpan.org/Public/Bug/Display.html?id=18397
874
