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

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

71 - add the opacity fill type - an adaptor that modifies the opacity of
72 another fill.

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

89 - release image row and comments memory on all error returns in gif
90 reader

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

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

128 - re-work most image file test files that require a library into
129 separate library present/not present files to remove stupidly long
130 conditionals
131
132 - don't treat rubthrough() outside the bounds of the target image as
133 an error.

141 - correct documentation of default of raw image interleave read
142 parameter
143 https://rt.cpan.org/Ticket/Display.html?id=42074
144
145 - add raw_ prefix to raw read parameters, though the original names
146 still work.
147
148 - fail the read if an invalid raw_interleave parameter is supplied
149
150 - warn if no interleave or raw_interleave parameter is supplied,
151 since the documented default was wrong, and incompatible with the
152 write format
153
154 - for reading raw images, if raw_storechannels > raw_datachannels,
155 set the extra channels in the image to 0
156

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

TC
203 - add limited tests for Imager::ExtUtils
204
205 - make Imager::ExtUtils->includes use an absolute path, since

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

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

TC
237Bug fixes:
238
e02d22d2
TC
239 - Possible security issue: The floating point sample path for image
240 based fills had a buffer overflow. This would overwrite the end of
241 a malloc()ed buffer with double precision floats.
242 http://rt.cpan.org/Ticket/Display.html?id=35324
6912d85a 243 CVE-2008-1928
e02d22d2 244
de470892
TC
245 - check that the result of fileno($fh) is defined rather than simply
246 true when read() or write() is supplied with an fh parameter.
247 http://rt.cpan.org/Ticket/Display.html?id=35139
248
249 - i_scale_axis() wasn't checking the result of i_img_new_ch()
250 resulting in a SIGSEGV when attempting to scale an image to a size
251 too large to fit in memory. This is a NULL pointer access issue,
252 not a buffer overflow.
253 Added a check for the failure.
254 scale_calculate() (and hence scale()) will now fail if any of the
255 scale size parameters are a reference.
256 http://rt.cpan.org/Ticket/Display.html?id=35172
257

TC
258 - Regression: filling a greyscale image with a hatch used the wrong
259 color channels from the supplied fg/bg colors.

265===========
266
242d7497
TC
267This release primarily contains changes to improve ease of use -
268rather than you having to convert images to the appropriate number of
269channels, Imager handles it internally. How to handle drawing colors
270and the default combine mode is a thornier problem left for some other
271release.
272
d1555273
TC
273 - the font libraries are now only initialized when needed.

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

317 parameters.

319

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

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

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

TC
351 - the old dynaload code used Mach API functions to load dynamic
352 libraries on Mac OS X. These APIs have been deprecated in OS X
353 10.5 and were causing some build problems.
354 So henceforth Imager uses the dlopen() family of functions, and you
355 will need version 10.3 or later of OS X.

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

659Imager 0.55 - 16 Dec 2006
660===========
661
662This is primarily a bug fix release.
663
664Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
665
666There is one new feature:
667
668 - the Win32 font driver now supports UTF8 (RT 22166)
669 http://www.cpanforum.com/threads/3276
670 http://rt.cpan.org/Ticket/Display.html?id=22166
671
672Several bugs were fixed:
673
674 - the string() method would not output the string "0"
675 http://rt.cpan.org/Public/Bug/Display.html?id=21770
676
677 - fills.c was failing to compile on Solaris 10 (compiler unknown)
678 http://rt.cpan.org/Public/Bug/Display.html?id=21944
679
680 - the gif_disposal and gif_user_input tags weren't being read from
681 the file correctly
682 http://rt.cpan.org/Public/Bug/Display.html?id=22192
683
684 - gif.c was failing to build under MSVC
685 http://rt.cpan.org/Ticket/Display.html?id=23922
686
687 - in some cases strings passed to the string() method were treated as
688 terminated by NUL (chr 0)
689 http://rt.cpan.org/Public/Bug/Display.html?id=21770
690
691 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
692 that's the default build name for zlib on Win32.
693 http://rt.cpan.org/Ticket/Display.html?id=23064
694
695 - search $Config{incpath} for headers too, which we should have been
696 doing all along.
697
698Win32 font driver fixes:
699
700 - the global descent value from bounding box was the wrong sign
701 http://www.cpanforum.com/threads/3276
702
703 - if the first or last glyph overflowed the left or right side of the
704 advance width they would be clipped
705
706
707Imager 0.54 - 14 Sep 2006
708===========
709
710This is primarily a feature release:
711
712 - a new qtype value 'mixing' has been added to the scale()
713 method. This is faster than 'normal', slower than 'preview'. This
714 is based on the method used by pnmscale, and seems to produce less
715 blurry results than normal.
716 http://rt.cpan.org/Public/Bug/Display.html?id=20677
717
718 - the rubthrough() method can now render onto images with an alpha
719 channel.
720 http://rt.cpan.org/Ticket/Display.html?id=20678
721
722 - the read_multi() method now falls back to calling doing a single
723 image read via the read() method and write_multi() will now fall
724 back to calling write() if a single image is supplied. This means
725 you can simply call the read_multi() or write_multi() functions
726 without having to check if the type is formatted by that method.
727 http://rt.cpan.org/Ticket/Display.html?id=19457
728 http://rt.cpan.org/Ticket/Display.html?id=19458
729
730 - the GIF loop extension can now be written. If you don't have
731 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
732 should upgrade.
733 http://rt.cpan.org/Ticket/Display.html?id=21185
734
735 - getscanline() and setscanline() can now read/write palette index
736 based data from/to the image for paletted images, by setting type to
737 'index'.
738 http://rt.cpan.org/Ticket/Display.html?id=20338
739
740 - we no longer hassle you to disable GIF support
741 http://rt.cpan.org/Ticket/Display.html?id=20687
742
743 - minor documentation fixes
744
745
746Imager 0.53 - 26 Jul 2006
747===========
748
749This is a bugfix release.
750
751Some test code was left in a code path not covered by the test
752suite. A test was added to cover this code path and the test code was
753removed.
754http://rt.cpan.org/Public/Bug/Display.html?id=20705
755
756
757Imager 0.52 - 25 Jul 2006
758===========
759
760This is primarily a feature release, but contains a fair few bug
761fixes, new features:
762
763 - ability to read and write MS Windows ICO and CUR files
764
765 - you can now add file format plugins to support new file formats
766
767 - add POD coverage tests
768
769 - setcolors() and addcolors() now accept color names and so on
770 instead of requiring Imager::Color objects.
771 http://rt.cpan.org/Ticket/Display.html?id=20056
772
773 - flood_fill() can now fill to a specified border color instead of
774 just to the area the same color as the seed.
775 http://rt.cpan.org/Ticket/Display.html?id=19618
776
777
778Bug fixes:
779
780 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
781 calculating the advance width.
782 http://rt.cpan.org/Public/Bug/Display.html?id=20554
783
784 - bounding_box for the T1 driver wasn't including leading and
785 trailing spaces in the bounding box as the other drivers did, it also
786 produced strange results for empty strings or strings containing only
787 spaces
788
789 - when reading CMYK jpeg images they were being transferred to the
790 image object as is, producing a four channel image. It only looked ok
791 due to an old still unfixed Photoshop bug. We now convert from the
792 inverted CMYK that photoshop (and Corel for example) produce into RGB.
793 http://rt.cpan.org/Ticket/Display.html?id=20416
794
795 - reading a CYMK TIFF would result in a 4 channel image, reading any
796 image with more than 4 channels (eg. RGB with 2 alpha channels) would
797 result in an error.
798 http://rt.cpan.org/Ticket/Display.html?id=20415
799
800 - added /usr/local/include to the default include search path, since
801 we were already searching /usr/local/lib for libraries.
802
803And various minor fixes and documentation updates.
804
805
806Imager 0.51 - 23 Apr 2006

826 or 4 channel image to jpeg or a 2 channel image to tga where the
827 output is an in-memeory buffer.
