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

101 - add the opacity fill type - an adaptor that modifies the opacity of
102 another fill.

TC
104Bug fixes:
105
106 - the conv filter now enforces that the sum of the coefficients is
107 non-zero. Also, rather than skipping pixels off the edge off the
108 edge of the image, the closest edge pixel is used. Previously
109 dividing by the zero sum of coefficients could cause invalid
110 results or runtime exceptions.
111 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
112 this bug.

118
119 - release image row and comments memory on all error returns in gif
120 reader
121
122 - handle zero length extensions, previously this would cause a null
123 pointer dereference
124 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.

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

158 - re-work most image file test files that require a library into
159 separate library present/not present files to remove stupidly long
160 conditionals

162 - don't treat rubthrough() outside the bounds of the target image as
163 an error.

171 - correct documentation of default of raw image interleave read
172 parameter
173 https://rt.cpan.org/Ticket/Display.html?id=42074
174
175 - add raw_ prefix to raw read parameters, though the original names
176 still work.
177
178 - fail the read if an invalid raw_interleave parameter is supplied
179
180 - warn if no interleave or raw_interleave parameter is supplied,
181 since the documented default was wrong, and incompatible with the
182 write format
183
184 - for reading raw images, if raw_storechannels > raw_datachannels,
185 set the extra channels in the image to 0
186
cd476e58
TC
187 - when probing for executables like freetype-config, search for .bat
188 and .cmd on MSWin32, as well as .exe.

TC
219 - an optimization skipping 0 src alpha values could cause the
220 rubthrough() to read past the end of a buffer.

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

TC
233 - add limited tests for Imager::ExtUtils
234
235 - make Imager::ExtUtils->includes use an absolute path, since

238
6b22ba84
TC
239 - re-arrange the POD for Imager::Font::BBox:
240 - mark total_width(), pos_width(), end_offset() obsolete, since
241 they're mostly for backwards compatibility
242 - group width methods and height methods

248Bug fixes:
249
250 - In some cases when an error occurs reading those parts of a JPEG
251 file after the image the scan-line buffer could be freed a second
252 time. In cases where the the error occured while reading the image
253 data it's possible that the buffer could have leaked.
254 Thanks to Gabriel Vasseur for reporting this and help in tracking
255 it down.

267Bug fixes:
268
e02d22d2
TC
269 - Possible security issue: The floating point sample path for image
270 based fills had a buffer overflow. This would overwrite the end of
271 a malloc()ed buffer with double precision floats.
272 http://rt.cpan.org/Ticket/Display.html?id=35324
6912d85a 273 CVE-2008-1928
e02d22d2 274
de470892
TC
275 - check that the result of fileno($fh) is defined rather than simply
276 true when read() or write() is supplied with an fh parameter.
277 http://rt.cpan.org/Ticket/Display.html?id=35139
278
279 - i_scale_axis() wasn't checking the result of i_img_new_ch()
280 resulting in a SIGSEGV when attempting to scale an image to a size
281 too large to fit in memory. This is a NULL pointer access issue,
282 not a buffer overflow.
283 Added a check for the failure.
284 scale_calculate() (and hence scale()) will now fail if any of the
285 scale size parameters are a reference.

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

295===========
296
242d7497
TC
297This release primarily contains changes to improve ease of use -
298rather than you having to convert images to the appropriate number of
299channels, Imager handles it internally. How to handle drawing colors
300and the default combine mode is a thornier problem left for some other
301release.
302

TC
303 - the font libraries are now only initialized when needed.

305
9b1ec2b8
TC
306 - moved the imtoc.perl code into Imager::Preprocess
307
308 - paste() and rubthrough() now adapt the source image data to the
309 destination, so you can now safely paste/rubthrough from greyscale
310 images to color images or back, or from alpha channel images to
311 noalpha channels or back.
312 https://rt.cpan.org/Ticket/Display.html?id=30908
313
314 - rubthrough() now falls back to pasting when the source doesn't have
315 an alpha channel. This effectively treats the source as having a
316 max alpha channel, the right thing to do.
317 http://rt.cpan.org/Ticket/Display.html?id=29944
318
319 - re-worked most of the area filling code to use a common set of
320 functions when filling.
321 Corrected normal combine mode.
322 Rewrote most of the combine modes to match the way the SVG draft
323 defines them with respect to a translucent source and destination.
324 Added tests for translucent source and destination.
325 Added tests to check 8-bit/sample and double/sample combines work
326 similarly.

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

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

TC
362 - some TGA images weren't being detected correctly as TGA images
363 https://rt.cpan.org/Ticket/Display.html?id=32925
364
365 - handling of the left-over bit for 16-bit/pixel TGA images has been
366 changed to match the behaviour of the GIMP. Previously the bit
367 being set was treated as an opaque pixel, but one user reported a
368 problem with loading such an image. I haven't been able to find any
369 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
370 I'll match it's behaviour. See issue 114913 in the GIMP's
371 bugzilla.

381 - the old dynaload code used Mach API functions to load dynamic
382 libraries on Mac OS X. These APIs have been deprecated in OS X
383 10.5 and were causing some build problems.
384 So henceforth Imager uses the dlopen() family of functions, and you
385 will need version 10.3 or later of OS X.

417 bits, exposed this at the perl level in getsamples()
418
419 - the conv filter now works at floating point precision for high bit
420 images

689Imager 0.55 - 16 Dec 2006
690===========
691
692This is primarily a bug fix release.
693
694Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
695
696There is one new feature:
697
698 - the Win32 font driver now supports UTF8 (RT 22166)
699 http://www.cpanforum.com/threads/3276
700 http://rt.cpan.org/Ticket/Display.html?id=22166
701
702Several bugs were fixed:
703
704 - the string() method would not output the string "0"
705 http://rt.cpan.org/Public/Bug/Display.html?id=21770
706
707 - fills.c was failing to compile on Solaris 10 (compiler unknown)
708 http://rt.cpan.org/Public/Bug/Display.html?id=21944
709
710 - the gif_disposal and gif_user_input tags weren't being read from
711 the file correctly
712 http://rt.cpan.org/Public/Bug/Display.html?id=22192
713
714 - gif.c was failing to build under MSVC
715 http://rt.cpan.org/Ticket/Display.html?id=23922
716
717 - in some cases strings passed to the string() method were treated as
718 terminated by NUL (chr 0)
719 http://rt.cpan.org/Public/Bug/Display.html?id=21770
720
721 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
722 that's the default build name for zlib on Win32.
723 http://rt.cpan.org/Ticket/Display.html?id=23064
724
725 - search $Config{incpath} for headers too, which we should have been
726 doing all along.
727
728Win32 font driver fixes:
729
730 - the global descent value from bounding box was the wrong sign
731 http://www.cpanforum.com/threads/3276
732
733 - if the first or last glyph overflowed the left or right side of the
734 advance width they would be clipped
735
736
737Imager 0.54 - 14 Sep 2006
738===========
739
740This is primarily a feature release:
741
742 - a new qtype value 'mixing' has been added to the scale()
743 method. This is faster than 'normal', slower than 'preview'. This
744 is based on the method used by pnmscale, and seems to produce less
745 blurry results than normal.
746 http://rt.cpan.org/Public/Bug/Display.html?id=20677
747
748 - the rubthrough() method can now render onto images with an alpha
749 channel.
750 http://rt.cpan.org/Ticket/Display.html?id=20678
751
752 - the read_multi() method now falls back to calling doing a single
753 image read via the read() method and write_multi() will now fall
754 back to calling write() if a single image is supplied. This means
755 you can simply call the read_multi() or write_multi() functions
756 without having to check if the type is formatted by that method.
757 http://rt.cpan.org/Ticket/Display.html?id=19457
758 http://rt.cpan.org/Ticket/Display.html?id=19458
759
760 - the GIF loop extension can now be written. If you don't have
761 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
762 should upgrade.
763 http://rt.cpan.org/Ticket/Display.html?id=21185
764
765 - getscanline() and setscanline() can now read/write palette index
766 based data from/to the image for paletted images, by setting type to
767 'index'.
768 http://rt.cpan.org/Ticket/Display.html?id=20338
769
770 - we no longer hassle you to disable GIF support
771 http://rt.cpan.org/Ticket/Display.html?id=20687
772
773 - minor documentation fixes
774
775
776Imager 0.53 - 26 Jul 2006
777===========
778
779This is a bugfix release.
780
781Some test code was left in a code path not covered by the test
782suite. A test was added to cover this code path and the test code was
783removed.
784http://rt.cpan.org/Public/Bug/Display.html?id=20705
785
786
787Imager 0.52 - 25 Jul 2006
788===========
789
790This is primarily a feature release, but contains a fair few bug
791fixes, new features:
792
793 - ability to read and write MS Windows ICO and CUR files
794
795 - you can now add file format plugins to support new file formats
796
797 - add POD coverage tests
798
799 - setcolors() and addcolors() now accept color names and so on
800 instead of requiring Imager::Color objects.
801 http://rt.cpan.org/Ticket/Display.html?id=20056
802
803 - flood_fill() can now fill to a specified border color instead of
804 just to the area the same color as the seed.
805 http://rt.cpan.org/Ticket/Display.html?id=19618
806
807
808Bug fixes:
809
810 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
811 calculating the advance width.
812 http://rt.cpan.org/Public/Bug/Display.html?id=20554
813
814 - bounding_box for the T1 driver wasn't including leading and
815 trailing spaces in the bounding box as the other drivers did, it also
816 produced strange results for empty strings or strings containing only
817 spaces
818
819 - when reading CMYK jpeg images they were being transferred to the
820 image object as is, producing a four channel image. It only looked ok
821 due to an old still unfixed Photoshop bug. We now convert from the
822 inverted CMYK that photoshop (and Corel for example) produce into RGB.
823 http://rt.cpan.org/Ticket/Display.html?id=20416
824
825 - reading a CYMK TIFF would result in a 4 channel image, reading any
826 image with more than 4 channels (eg. RGB with 2 alpha channels) would
827 result in an error.
828 http://rt.cpan.org/Ticket/Display.html?id=20415
829
830 - added /usr/local/include to the default include search path, since
831 we were already searching /usr/local/lib for libraries.
832
833And various minor fixes and documentation updates.
834
835
836Imager 0.51 - 23 Apr 2006

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