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

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

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

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

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

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

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

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

227===========
228
242d7497
TC
229This release primarily contains changes to improve ease of use -
230rather than you having to convert images to the appropriate number of
231channels, Imager handles it internally. How to handle drawing colors
232and the default combine mode is a thornier problem left for some other
233release.
234

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

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

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

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

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

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

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

469 indexes outside the range of colors defined by the image's palette.

476 - to avoid confusion, channels not present in the image are returned as

479 channels.

621Imager 0.55 - 16 Dec 2006
622===========
623
624This is primarily a bug fix release.
625
626Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
627
628There is one new feature:
629
630 - the Win32 font driver now supports UTF8 (RT 22166)
631 http://www.cpanforum.com/threads/3276
632 http://rt.cpan.org/Ticket/Display.html?id=22166
633
634Several bugs were fixed:
635
636 - the string() method would not output the string "0"
637 http://rt.cpan.org/Public/Bug/Display.html?id=21770
638
639 - fills.c was failing to compile on Solaris 10 (compiler unknown)
640 http://rt.cpan.org/Public/Bug/Display.html?id=21944
641
642 - the gif_disposal and gif_user_input tags weren't being read from
643 the file correctly
644 http://rt.cpan.org/Public/Bug/Display.html?id=22192
645
646 - gif.c was failing to build under MSVC
647 http://rt.cpan.org/Ticket/Display.html?id=23922
648
649 - in some cases strings passed to the string() method were treated as
650 terminated by NUL (chr 0)
651 http://rt.cpan.org/Public/Bug/Display.html?id=21770
652
653 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
654 that's the default build name for zlib on Win32.
655 http://rt.cpan.org/Ticket/Display.html?id=23064
656
657 - search $Config{incpath} for headers too, which we should have been
658 doing all along.
659
660Win32 font driver fixes:
661
662 - the global descent value from bounding box was the wrong sign
663 http://www.cpanforum.com/threads/3276
664
665 - if the first or last glyph overflowed the left or right side of the
666 advance width they would be clipped
667
668
669Imager 0.54 - 14 Sep 2006
670===========
671
672This is primarily a feature release:
673
674 - a new qtype value 'mixing' has been added to the scale()
675 method. This is faster than 'normal', slower than 'preview'. This
676 is based on the method used by pnmscale, and seems to produce less
677 blurry results than normal.
678 http://rt.cpan.org/Public/Bug/Display.html?id=20677
679
680 - the rubthrough() method can now render onto images with an alpha
681 channel.
682 http://rt.cpan.org/Ticket/Display.html?id=20678
683
684 - the read_multi() method now falls back to calling doing a single
685 image read via the read() method and write_multi() will now fall
686 back to calling write() if a single image is supplied. This means
687 you can simply call the read_multi() or write_multi() functions
688 without having to check if the type is formatted by that method.
689 http://rt.cpan.org/Ticket/Display.html?id=19457
690 http://rt.cpan.org/Ticket/Display.html?id=19458
691
692 - the GIF loop extension can now be written. If you don't have
693 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
694 should upgrade.
695 http://rt.cpan.org/Ticket/Display.html?id=21185
696
697 - getscanline() and setscanline() can now read/write palette index
698 based data from/to the image for paletted images, by setting type to
699 'index'.
700 http://rt.cpan.org/Ticket/Display.html?id=20338
701
702 - we no longer hassle you to disable GIF support
703 http://rt.cpan.org/Ticket/Display.html?id=20687
704
705 - minor documentation fixes
706
707
708Imager 0.53 - 26 Jul 2006
709===========
710
711This is a bugfix release.
712
713Some test code was left in a code path not covered by the test
714suite. A test was added to cover this code path and the test code was
715removed.
716http://rt.cpan.org/Public/Bug/Display.html?id=20705
717
718
719Imager 0.52 - 25 Jul 2006
720===========
721
722This is primarily a feature release, but contains a fair few bug
723fixes, new features:
724
725 - ability to read and write MS Windows ICO and CUR files
726
727 - you can now add file format plugins to support new file formats
728
729 - add POD coverage tests
730
731 - setcolors() and addcolors() now accept color names and so on
732 instead of requiring Imager::Color objects.
733 http://rt.cpan.org/Ticket/Display.html?id=20056
734
735 - flood_fill() can now fill to a specified border color instead of
736 just to the area the same color as the seed.
737 http://rt.cpan.org/Ticket/Display.html?id=19618
738
739
740Bug fixes:
741
742 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
743 calculating the advance width.
744 http://rt.cpan.org/Public/Bug/Display.html?id=20554
745
746 - bounding_box for the T1 driver wasn't including leading and
747 trailing spaces in the bounding box as the other drivers did, it also
748 produced strange results for empty strings or strings containing only
749 spaces
750
751 - when reading CMYK jpeg images they were being transferred to the
752 image object as is, producing a four channel image. It only looked ok
753 due to an old still unfixed Photoshop bug. We now convert from the
754 inverted CMYK that photoshop (and Corel for example) produce into RGB.
755 http://rt.cpan.org/Ticket/Display.html?id=20416
756
757 - reading a CYMK TIFF would result in a 4 channel image, reading any
758 image with more than 4 channels (eg. RGB with 2 alpha channels) would
759 result in an error.
760 http://rt.cpan.org/Ticket/Display.html?id=20415
761
762 - added /usr/local/include to the default include search path, since
763 we were already searching /usr/local/lib for libraries.
764
765And various minor fixes and documentation updates.
766
767
768Imager 0.51 - 23 Apr 2006

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

784Imager 0.50 - 29 Mar 2006
785===========

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