35 perls where it's expected to work, and only if the threads module
36 can be loaded.

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

68 - add the opacity fill type - an adaptor that modifies the opacity of
69 another fill.

TC
71Bug fixes:
72
73 - the conv filter now enforces that the sum of the coefficients is
74 non-zero. Also, rather than skipping pixels off the edge off the
75 edge of the image, the closest edge pixel is used. Previously
76 dividing by the zero sum of coefficients could cause invalid
77 results or runtime exceptions.
78 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
79 this bug.

86 - release image row and comments memory on all error returns in gif
87 reader

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

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

125 - re-work most image file test files that require a library into
126 separate library present/not present files to remove stupidly long
127 conditionals

138 - correct documentation of default of raw image interleave read
139 parameter
140 https://rt.cpan.org/Ticket/Display.html?id=42074
141
142 - add raw_ prefix to raw read parameters, though the original names
143 still work.
144
145 - fail the read if an invalid raw_interleave parameter is supplied
146
147 - warn if no interleave or raw_interleave parameter is supplied,
148 since the documented default was wrong, and incompatible with the
149 write format
150
151 - for reading raw images, if raw_storechannels > raw_datachannels,
152 set the extra channels in the image to 0
153

TC
190 - corrected a reference leak where writing GIFs would leak memory.
191 This could also happen calling to_paletted().
192 Also documented the underlying long existing feature where the
193 colors parameter is filled with the generated color table and added
194 tests for it.

c586eb58
TC
200 - add limited tests for Imager::ExtUtils
201
202 - make Imager::ExtUtils->includes use an absolute path, since
203 a relative path could cause failures using Inline::C.

205
6b22ba84
TC
206 - re-arrange the POD for Imager::Font::BBox:
207 - mark total_width(), pos_width(), end_offset() obsolete, since
208 they're mostly for backwards compatibility
209 - group width methods and height methods

213===========
214
215Bug fixes:
216
217 - In some cases when an error occurs reading those parts of a JPEG
218 file after the image the scan-line buffer could be freed a second
219 time. In cases where the the error occured while reading the image
220 data it's possible that the buffer could have leaked.
221 Thanks to Gabriel Vasseur for reporting this and help in tracking
222 it down.

224 - the gif_screen_height tag was overriding the screen width and being
225 ignored for the screen height when present.

TC
234Bug fixes:
235
e02d22d2
TC
236 - Possible security issue: The floating point sample path for image
237 based fills had a buffer overflow. This would overwrite the end of
238 a malloc()ed buffer with double precision floats.

6912d85a 240 CVE-2008-1928
e02d22d2 241
de470892
TC
242 - check that the result of fileno($fh) is defined rather than simply
243 true when read() or write() is supplied with an fh parameter.
244 http://rt.cpan.org/Ticket/Display.html?id=35139
245
246 - i_scale_axis() wasn't checking the result of i_img_new_ch()
247 resulting in a SIGSEGV when attempting to scale an image to a size
248 too large to fit in memory. This is a NULL pointer access issue,
249 not a buffer overflow.
250 Added a check for the failure.
251 scale_calculate() (and hence scale()) will now fail if any of the
252 scale size parameters are a reference.
253 http://rt.cpan.org/Ticket/Display.html?id=35172
254
04f85f63
TC
255 - Regression: filling a greyscale image with a hatch used the wrong
256 color channels from the supplied fg/bg colors.
257 https://rt.cpan.org/Ticket/Display.html?id=35278
258

262===========
263
242d7497
TC
264This release primarily contains changes to improve ease of use -
265rather than you having to convert images to the appropriate number of
266channels, Imager handles it internally. How to handle drawing colors
267and the default combine mode is a thornier problem left for some other
268release.
269
d1555273
TC
270 - the font libraries are now only initialized when needed.

272
9b1ec2b8
TC
273 - moved the imtoc.perl code into Imager::Preprocess
274
275 - paste() and rubthrough() now adapt the source image data to the
276 destination, so you can now safely paste/rubthrough from greyscale
277 images to color images or back, or from alpha channel images to
278 noalpha channels or back.
279 https://rt.cpan.org/Ticket/Display.html?id=30908
280
281 - rubthrough() now falls back to pasting when the source doesn't have
282 an alpha channel. This effectively treats the source as having a
283 max alpha channel, the right thing to do.
284 http://rt.cpan.org/Ticket/Display.html?id=29944
285
286 - re-worked most of the area filling code to use a common set of
287 functions when filling.
288 Corrected normal combine mode.
289 Rewrote most of the combine modes to match the way the SVG draft
290 defines them with respect to a translucent source and destination.
291 Added tests for translucent source and destination.
292 Added tests to check 8-bit/sample and double/sample combines work
293 similarly.

314 parameters.

316

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

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

TC
329 - some TGA images weren't being detected correctly as TGA images
330 https://rt.cpan.org/Ticket/Display.html?id=32925
331
332 - handling of the left-over bit for 16-bit/pixel TGA images has been
333 changed to match the behaviour of the GIMP. Previously the bit
334 being set was treated as an opaque pixel, but one user reported a
335 problem with loading such an image. I haven't been able to find any
336 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
337 I'll match it's behaviour. See issue 114913 in the GIMP's
338 bugzilla.

TC
348 - the old dynaload code used Mach API functions to load dynamic
349 libraries on Mac OS X. These APIs have been deprecated in OS X
350 10.5 and were causing some build problems.
351 So henceforth Imager uses the dlopen() family of functions, and you
352 will need version 10.3 or later of OS X.

495 - the mask for ICO/CUR images is now applied as an alpha channel to

656Imager 0.55 - 16 Dec 2006
657===========
658
659This is primarily a bug fix release.
660
661Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
662
663There is one new feature:
664
665 - the Win32 font driver now supports UTF8 (RT 22166)
666 http://www.cpanforum.com/threads/3276
667 http://rt.cpan.org/Ticket/Display.html?id=22166
668
669Several bugs were fixed:
670
671 - the string() method would not output the string "0"
672 http://rt.cpan.org/Public/Bug/Display.html?id=21770
673
674 - fills.c was failing to compile on Solaris 10 (compiler unknown)
675 http://rt.cpan.org/Public/Bug/Display.html?id=21944
676
677 - the gif_disposal and gif_user_input tags weren't being read from
678 the file correctly
679 http://rt.cpan.org/Public/Bug/Display.html?id=22192
680
681 - gif.c was failing to build under MSVC
682 http://rt.cpan.org/Ticket/Display.html?id=23922
683
684 - in some cases strings passed to the string() method were treated as
685 terminated by NUL (chr 0)
686 http://rt.cpan.org/Public/Bug/Display.html?id=21770
687
688 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
689 that's the default build name for zlib on Win32.
690 http://rt.cpan.org/Ticket/Display.html?id=23064
691
692 - search $Config{incpath} for headers too, which we should have been
693 doing all along.
694
695Win32 font driver fixes:
696
697 - the global descent value from bounding box was the wrong sign
698 http://www.cpanforum.com/threads/3276
699
700 - if the first or last glyph overflowed the left or right side of the
701 advance width they would be clipped
702
703
704Imager 0.54 - 14 Sep 2006
705===========
706
707This is primarily a feature release:
708
709 - a new qtype value 'mixing' has been added to the scale()
710 method. This is faster than 'normal', slower than 'preview'. This
711 is based on the method used by pnmscale, and seems to produce less
712 blurry results than normal.
713 http://rt.cpan.org/Public/Bug/Display.html?id=20677
714
715 - the rubthrough() method can now render onto images with an alpha
716 channel.
717 http://rt.cpan.org/Ticket/Display.html?id=20678
718
719 - the read_multi() method now falls back to calling doing a single
720 image read via the read() method and write_multi() will now fall
721 back to calling write() if a single image is supplied. This means
722 you can simply call the read_multi() or write_multi() functions
723 without having to check if the type is formatted by that method.
724 http://rt.cpan.org/Ticket/Display.html?id=19457
725 http://rt.cpan.org/Ticket/Display.html?id=19458
726
727 - the GIF loop extension can now be written. If you don't have
728 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
729 should upgrade.
730 http://rt.cpan.org/Ticket/Display.html?id=21185
731
732 - getscanline() and setscanline() can now read/write palette index
733 based data from/to the image for paletted images, by setting type to
734 'index'.
735 http://rt.cpan.org/Ticket/Display.html?id=20338
736
737 - we no longer hassle you to disable GIF support
738 http://rt.cpan.org/Ticket/Display.html?id=20687
739
740 - minor documentation fixes
741
742
743Imager 0.53 - 26 Jul 2006
744===========
745
746This is a bugfix release.
747
748Some test code was left in a code path not covered by the test
749suite. A test was added to cover this code path and the test code was
750removed.
751http://rt.cpan.org/Public/Bug/Display.html?id=20705
752
753
754Imager 0.52 - 25 Jul 2006
755===========
756
757This is primarily a feature release, but contains a fair few bug
758fixes, new features:
759
760 - ability to read and write MS Windows ICO and CUR files
761
762 - you can now add file format plugins to support new file formats
763
764 - add POD coverage tests
765
766 - setcolors() and addcolors() now accept color names and so on
767 instead of requiring Imager::Color objects.
768 http://rt.cpan.org/Ticket/Display.html?id=20056
769
770 - flood_fill() can now fill to a specified border color instead of
771 just to the area the same color as the seed.
772 http://rt.cpan.org/Ticket/Display.html?id=19618
773
774
775Bug fixes:
776
777 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
778 calculating the advance width.
779 http://rt.cpan.org/Public/Bug/Display.html?id=20554
780
781 - bounding_box for the T1 driver wasn't including leading and
782 trailing spaces in the bounding box as the other drivers did, it also
783 produced strange results for empty strings or strings containing only
784 spaces
785
786 - when reading CMYK jpeg images they were being transferred to the
787 image object as is, producing a four channel image. It only looked ok
788 due to an old still unfixed Photoshop bug. We now convert from the
789 inverted CMYK that photoshop (and Corel for example) produce into RGB.
790 http://rt.cpan.org/Ticket/Display.html?id=20416
791
792 - reading a CYMK TIFF would result in a 4 channel image, reading any
793 image with more than 4 channels (eg. RGB with 2 alpha channels) would
794 result in an error.
795 http://rt.cpan.org/Ticket/Display.html?id=20415
796
797 - added /usr/local/include to the default include search path, since
798 we were already searching /usr/local/lib for libraries.
799
800And various minor fixes and documentation updates.
801
802
