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

32 - add the opacity fill type - an adaptor that modifies the opacity of
33 another fill.

35Bug fixes:
36
37 - the conv filter now enforces that the sum of the coefficients is
38 non-zero. Also, rather than skipping pixels off the edge off the
39 edge of the image, the closest edge pixel is used. Previously
40 dividing by the zero sum of coefficients could cause invalid
41 results or runtime exceptions.
42 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
43 this bug.

53 - handle zero length extensions, previously this would cause a null
54 pointer dereference
55 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.

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

110
111 - warn if no interleave or raw_interleave parameter is supplied,
112 since the documented default was wrong, and incompatible with the
113 write format

116 set the extra channels in the image to 0

179Bug fixes:
180
181 - In some cases when an error occurs reading those parts of a JPEG
182 file after the image the scan-line buffer could be freed a second
183 time. In cases where the the error occured while reading the image
184 data it's possible that the buffer could have leaked.
185 Thanks to Gabriel Vasseur for reporting this and help in tracking
186 it down.

e02d22d2
TC
200 - Possible security issue: The floating point sample path for image
201 based fills had a buffer overflow. This would overwrite the end of
202 a malloc()ed buffer with double precision floats.
203 http://rt.cpan.org/Ticket/Display.html?id=35324
6912d85a 204 CVE-2008-1928
e02d22d2 205
de470892
TC
206 - check that the result of fileno($fh) is defined rather than simply
207 true when read() or write() is supplied with an fh parameter.
208 http://rt.cpan.org/Ticket/Display.html?id=35139
209
210 - i_scale_axis() wasn't checking the result of i_img_new_ch()
211 resulting in a SIGSEGV when attempting to scale an image to a size
212 too large to fit in memory. This is a NULL pointer access issue,
213 not a buffer overflow.
214 Added a check for the failure.
215 scale_calculate() (and hence scale()) will now fail if any of the
216 scale size parameters are a reference.
217 http://rt.cpan.org/Ticket/Display.html?id=35172

219 - Regression: filling a greyscale image with a hatch used the wrong

226===========
227
242d7497
TC
228This release primarily contains changes to improve ease of use -
229rather than you having to convert images to the appropriate number of
230channels, Imager handles it internally. How to handle drawing colors
231and the default combine mode is a thornier problem left for some other
232release.
233

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

236
9b1ec2b8
TC
237 - moved the imtoc.perl code into Imager::Preprocess
238
239 - paste() and rubthrough() now adapt the source image data to the
240 destination, so you can now safely paste/rubthrough from greyscale
241 images to color images or back, or from alpha channel images to
242 noalpha channels or back.
243 https://rt.cpan.org/Ticket/Display.html?id=30908
244
245 - rubthrough() now falls back to pasting when the source doesn't have
246 an alpha channel. This effectively treats the source as having a
247 max alpha channel, the right thing to do.
248 http://rt.cpan.org/Ticket/Display.html?id=29944
249
250 - re-worked most of the area filling code to use a common set of
251 functions when filling.
252 Corrected normal combine mode.
253 Rewrote most of the combine modes to match the way the SVG draft
254 defines them with respect to a translucent source and destination.
255 Added tests for translucent source and destination.
256 Added tests to check 8-bit/sample and double/sample combines work
257 similarly.

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

286 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
287 Noticed when I saw:
288 https://bugzilla.redhat.com/show_bug.cgi?id=166254
289 I'm not changing the #! lines of the sample code, since it's sample
290 code, not intended for installation.
291 http://rt.cpan.org/Ticket/Display.html?id=33408

TC
293 - some TGA images weren't being detected correctly as TGA images
294 https://rt.cpan.org/Ticket/Display.html?id=32925
295
296 - handling of the left-over bit for 16-bit/pixel TGA images has been
297 changed to match the behaviour of the GIMP. Previously the bit
298 being set was treated as an opaque pixel, but one user reported a
299 problem with loading such an image. I haven't been able to find any
300 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
301 I'll match it's behaviour. See issue 114913 in the GIMP's
302 bugzilla.

TC
312 - the old dynaload code used Mach API functions to load dynamic
313 libraries on Mac OS X. These APIs have been deprecated in OS X
314 10.5 and were causing some build problems.
315 So henceforth Imager uses the dlopen() family of functions, and you
316 will need version 10.3 or later of OS X.

459 - the mask for ICO/CUR images is now applied as an alpha channel to
460 the returned image. For the old behaviour, supply ico_masked => 0
461 to read() or read_multi(). This should be less confusing when
462 using Imager as a general image processor.

467 - in some cases it's possible for giflib/libungif to return color
468 indexes outside the range of colors defined by the image's palette.
469 We now expand the palette to match the indexes used.
470 Thanks to Gabriel Vasseur for reporting this.

475 - to avoid confusion, channels not present in the image are returned as
476 zero by getscanline(). This has no effect on the C level i_glin()

478 channels.

620Imager 0.55 - 16 Dec 2006
621===========
622
623This is primarily a bug fix release.
624
625Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
626
627There is one new feature:
628
629 - the Win32 font driver now supports UTF8 (RT 22166)
630 http://www.cpanforum.com/threads/3276
631 http://rt.cpan.org/Ticket/Display.html?id=22166
632
633Several bugs were fixed:
634
635 - the string() method would not output the string "0"
636 http://rt.cpan.org/Public/Bug/Display.html?id=21770
637
638 - fills.c was failing to compile on Solaris 10 (compiler unknown)
639 http://rt.cpan.org/Public/Bug/Display.html?id=21944
640
641 - the gif_disposal and gif_user_input tags weren't being read from
642 the file correctly
643 http://rt.cpan.org/Public/Bug/Display.html?id=22192
644
645 - gif.c was failing to build under MSVC
646 http://rt.cpan.org/Ticket/Display.html?id=23922
647
648 - in some cases strings passed to the string() method were treated as
649 terminated by NUL (chr 0)
650 http://rt.cpan.org/Public/Bug/Display.html?id=21770
651
652 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
653 that's the default build name for zlib on Win32.
654 http://rt.cpan.org/Ticket/Display.html?id=23064
655
656 - search $Config{incpath} for headers too, which we should have been
657 doing all along.
658
659Win32 font driver fixes:
660
661 - the global descent value from bounding box was the wrong sign
662 http://www.cpanforum.com/threads/3276
663
664 - if the first or last glyph overflowed the left or right side of the
665 advance width they would be clipped
666
667
668Imager 0.54 - 14 Sep 2006
669===========
670
671This is primarily a feature release:
672
673 - a new qtype value 'mixing' has been added to the scale()
674 method. This is faster than 'normal', slower than 'preview'. This
675 is based on the method used by pnmscale, and seems to produce less
676 blurry results than normal.
677 http://rt.cpan.org/Public/Bug/Display.html?id=20677
678
679 - the rubthrough() method can now render onto images with an alpha
680 channel.
681 http://rt.cpan.org/Ticket/Display.html?id=20678
682
683 - the read_multi() method now falls back to calling doing a single
684 image read via the read() method and write_multi() will now fall
685 back to calling write() if a single image is supplied. This means
686 you can simply call the read_multi() or write_multi() functions
687 without having to check if the type is formatted by that method.
688 http://rt.cpan.org/Ticket/Display.html?id=19457
689 http://rt.cpan.org/Ticket/Display.html?id=19458
690
691 - the GIF loop extension can now be written. If you don't have
692 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
693 should upgrade.
694 http://rt.cpan.org/Ticket/Display.html?id=21185
695
696 - getscanline() and setscanline() can now read/write palette index
697 based data from/to the image for paletted images, by setting type to
698 'index'.
699 http://rt.cpan.org/Ticket/Display.html?id=20338
700
701 - we no longer hassle you to disable GIF support
702 http://rt.cpan.org/Ticket/Display.html?id=20687
703
704 - minor documentation fixes
705
706
707Imager 0.53 - 26 Jul 2006
708===========
709
710This is a bugfix release.
711
712Some test code was left in a code path not covered by the test
713suite. A test was added to cover this code path and the test code was
714removed.
715http://rt.cpan.org/Public/Bug/Display.html?id=20705
716
717
718Imager 0.52 - 25 Jul 2006
719===========
720
721This is primarily a feature release, but contains a fair few bug
722fixes, new features:
723
724 - ability to read and write MS Windows ICO and CUR files
725
726 - you can now add file format plugins to support new file formats
727
728 - add POD coverage tests
729
730 - setcolors() and addcolors() now accept color names and so on
731 instead of requiring Imager::Color objects.
732 http://rt.cpan.org/Ticket/Display.html?id=20056
733
734 - flood_fill() can now fill to a specified border color instead of
735 just to the area the same color as the seed.
736 http://rt.cpan.org/Ticket/Display.html?id=19618
737
738
739Bug fixes:
740
741 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
742 calculating the advance width.
743 http://rt.cpan.org/Public/Bug/Display.html?id=20554
744
745 - bounding_box for the T1 driver wasn't including leading and
746 trailing spaces in the bounding box as the other drivers did, it also
747 produced strange results for empty strings or strings containing only
748 spaces
749
750 - when reading CMYK jpeg images they were being transferred to the
751 image object as is, producing a four channel image. It only looked ok
752 due to an old still unfixed Photoshop bug. We now convert from the
753 inverted CMYK that photoshop (and Corel for example) produce into RGB.
754 http://rt.cpan.org/Ticket/Display.html?id=20416
755
756 - reading a CYMK TIFF would result in a 4 channel image, reading any
757 image with more than 4 channels (eg. RGB with 2 alpha channels) would
758 result in an error.
759 http://rt.cpan.org/Ticket/Display.html?id=20415
760
761 - added /usr/local/include to the default include search path, since
762 we were already searching /usr/local/lib for libraries.
763
764And various minor fixes and documentation updates.
765
766
767Imager 0.51 - 23 Apr 2006

773
774 - fix mis-processing of the src_maxx and src_maxy parameters of the

783Imager 0.50 - 29 Mar 2006
784===========

786 - CRITICAL: fixes a segmentation fault from attempting to write a 2
787 or 4 channel image to jpeg or a 2 channel image to tga where the
788 output is an in-memeory buffer.
789 http://rt.cpan.org/Public/Bug/Display.html?id=18397
790
791 - fixes an incorrect pointer parameter in the PNG code
