9==============
10
11 - further adjust the threads test so it only performs the tests on
12 perls where it's expected to work, and only if the threads module
13 can be loaded.

24Bug fixes:
25
26 - use scanline oriented operations to flip images instead of pixel
27 operations
28 https://rt.cpan.org/Ticket/Display.html?id=39278
29
30 - use double/sample operations to flip large sample images instead of
31 8-bit sample operations.

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

45 - add the opacity fill type - an adaptor that modifies the opacity of
46 another fill.

TC
48Bug fixes:
49
50 - the conv filter now enforces that the sum of the coefficients is
51 non-zero. Also, rather than skipping pixels off the edge off the
52 edge of the image, the closest edge pixel is used. Previously
53 dividing by the zero sum of coefficients could cause invalid
54 results or runtime exceptions.
55 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
56 this bug.

59===========

61Bug fixes:
62
63 - release image row and comments memory on all error returns in gif
64 reader
65
66 - handle zero length extensions, previously this would cause a null
67 pointer dereference
68 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.

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

115 - correct documentation of default of raw image interleave read
116 parameter
117 https://rt.cpan.org/Ticket/Display.html?id=42074
118
119 - add raw_ prefix to raw read parameters, though the original names
120 still work.
121
122 - fail the read if an invalid raw_interleave parameter is supplied
123
124 - warn if no interleave or raw_interleave parameter is supplied,
125 since the documented default was wrong, and incompatible with the
126 write format
127
128 - for reading raw images, if raw_storechannels > raw_datachannels,
129 set the extra channels in the image to 0
130
cd476e58
TC
131 - when probing for executables like freetype-config, search for .bat

6b22ba84
TC
163 - an optimization skipping 0 src alpha values could cause the
164 rubthrough() to read past the end of a buffer.

166
5c0d0ddf
TC
167 - corrected a reference leak where writing GIFs would leak memory.
168 This could also happen calling to_paletted().
169 Also documented the underlying long existing feature where the
170 colors parameter is filled with the generated color table and added
171 tests for it.

176
c586eb58
TC
177 - add limited tests for Imager::ExtUtils
178
179 - make Imager::ExtUtils->includes use an absolute path, since
180 a relative path could cause failures using Inline::C.

182
6b22ba84
TC
183 - re-arrange the POD for Imager::Font::BBox:
184 - mark total_width(), pos_width(), end_offset() obsolete, since
185 they're mostly for backwards compatibility
186 - group width methods and height methods

TC
190===========
191
192Bug fixes:
193
194 - In some cases when an error occurs reading those parts of a JPEG
195 file after the image the scan-line buffer could be freed a second
196 time. In cases where the the error occured while reading the image
197 data it's possible that the buffer could have leaked.
198 Thanks to Gabriel Vasseur for reporting this and help in tracking
199 it down.

208This is a bug fix release. This includes a fix for a possible
209security issue.

TC
211Bug fixes:
212
e02d22d2
TC
213 - Possible security issue: The floating point sample path for image
214 based fills had a buffer overflow. This would overwrite the end of
215 a malloc()ed buffer with double precision floats.
216 http://rt.cpan.org/Ticket/Display.html?id=35324
6912d85a 217 CVE-2008-1928
e02d22d2 218
de470892
TC
219 - check that the result of fileno($fh) is defined rather than simply
220 true when read() or write() is supplied with an fh parameter.
221 http://rt.cpan.org/Ticket/Display.html?id=35139
222
223 - i_scale_axis() wasn't checking the result of i_img_new_ch()
224 resulting in a SIGSEGV when attempting to scale an image to a size
225 too large to fit in memory. This is a NULL pointer access issue,
226 not a buffer overflow.
227 Added a check for the failure.
228 scale_calculate() (and hence scale()) will now fail if any of the
229 scale size parameters are a reference.
230 http://rt.cpan.org/Ticket/Display.html?id=35172
231
04f85f63
TC
232 - Regression: filling a greyscale image with a hatch used the wrong
233 color channels from the supplied fg/bg colors.
234 https://rt.cpan.org/Ticket/Display.html?id=35278
235

TC
236 - fixed a related problem for image fills.

TC
239===========
240
242d7497
TC
241This release primarily contains changes to improve ease of use -
242rather than you having to convert images to the appropriate number of
243channels, Imager handles it internally. How to handle drawing colors
244and the default combine mode is a thornier problem left for some other
245release.
246
d1555273
TC
247 - the font libraries are now only initialized when needed.

249
9b1ec2b8
TC
250 - moved the imtoc.perl code into Imager::Preprocess
251
252 - paste() and rubthrough() now adapt the source image data to the
253 destination, so you can now safely paste/rubthrough from greyscale
254 images to color images or back, or from alpha channel images to
255 noalpha channels or back.
256 https://rt.cpan.org/Ticket/Display.html?id=30908
257
258 - rubthrough() now falls back to pasting when the source doesn't have
259 an alpha channel. This effectively treats the source as having a
260 max alpha channel, the right thing to do.
261 http://rt.cpan.org/Ticket/Display.html?id=29944
262
263 - re-worked most of the area filling code to use a common set of
264 functions when filling.
265 Corrected normal combine mode.
266 Rewrote most of the combine modes to match the way the SVG draft
267 defines them with respect to a translucent source and destination.
268 Added tests for translucent source and destination.
269 Added tests to check 8-bit/sample and double/sample combines work
270 similarly.

273 - writing a 2 or 4 channel image to a JPEG file will now write that
274 image as if composited against a background, black by default,
275 overridable with the i_background tag/parameter.

288Bug fixes:
289
290 - Imager::Matrix2d->translate() now only requires one of the x or y
291 parameters.
292 http://rt.cpan.org/Ticket/Display.html?id=29937
293
2757bad0
TC
294 - mixing qtype scaling now sets all channels of a pixel to zero if
295 the pixel has zero coverage (zero alpha). This should produce more
296 compressible output files.
297 http://rt.cpan.org/Ticket/Display.html?id=32324
298
3da08517
TC
299 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
300 Noticed when I saw:
301 https://bugzilla.redhat.com/show_bug.cgi?id=166254
302 I'm not changing the #! lines of the sample code, since it's sample
303 code, not intended for installation.
304 http://rt.cpan.org/Ticket/Display.html?id=33408
305
242d7497
TC
306 - some TGA images weren't being detected correctly as TGA images
307 https://rt.cpan.org/Ticket/Display.html?id=32925
308
309 - handling of the left-over bit for 16-bit/pixel TGA images has been
310 changed to match the behaviour of the GIMP. Previously the bit
311 being set was treated as an opaque pixel, but one user reported a
312 problem with loading such an image. I haven't been able to find any
313 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
314 I'll match it's behaviour. See issue 114913 in the GIMP's
315 bugzilla.

321 - Makefile.PL now expands ~/path supplied to --incpath or --libpath

TC
325 - the old dynaload code used Mach API functions to load dynamic
326 libraries on Mac OS X. These APIs have been deprecated in OS X
327 10.5 and were causing some build problems.
328 So henceforth Imager uses the dlopen() family of functions, and you
329 will need version 10.3 or later of OS X.
330

361 bits, exposed this at the perl level in getsamples()
362
363 - the conv filter now works at floating point precision for high bit
364 images

460 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
461 now has full SGI RGB image format, including RLE and 16-bit/sample
462 images.

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

480 - in some cases it's possible for giflib/libungif to return color
481 indexes outside the range of colors defined by the image's palette.
482 We now expand the palette to match the indexes used.

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

491 channels.

633Imager 0.55 - 16 Dec 2006
634===========
635
636This is primarily a bug fix release.
637
638Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
639
640There is one new feature:
641
642 - the Win32 font driver now supports UTF8 (RT 22166)
643 http://www.cpanforum.com/threads/3276
644 http://rt.cpan.org/Ticket/Display.html?id=22166
645
646Several bugs were fixed:
647
648 - the string() method would not output the string "0"
649 http://rt.cpan.org/Public/Bug/Display.html?id=21770
650
651 - fills.c was failing to compile on Solaris 10 (compiler unknown)
652 http://rt.cpan.org/Public/Bug/Display.html?id=21944
653
654 - the gif_disposal and gif_user_input tags weren't being read from
655 the file correctly
656 http://rt.cpan.org/Public/Bug/Display.html?id=22192
657
658 - gif.c was failing to build under MSVC
659 http://rt.cpan.org/Ticket/Display.html?id=23922
660
661 - in some cases strings passed to the string() method were treated as
662 terminated by NUL (chr 0)
663 http://rt.cpan.org/Public/Bug/Display.html?id=21770
664
665 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
666 that's the default build name for zlib on Win32.
667 http://rt.cpan.org/Ticket/Display.html?id=23064
668
669 - search $Config{incpath} for headers too, which we should have been
670 doing all along.
671
672Win32 font driver fixes:
673
674 - the global descent value from bounding box was the wrong sign
675 http://www.cpanforum.com/threads/3276
676
677 - if the first or last glyph overflowed the left or right side of the
678 advance width they would be clipped
679
680
681Imager 0.54 - 14 Sep 2006
682===========
683
684This is primarily a feature release:
685
686 - a new qtype value 'mixing' has been added to the scale()
687 method. This is faster than 'normal', slower than 'preview'. This
688 is based on the method used by pnmscale, and seems to produce less
689 blurry results than normal.
690 http://rt.cpan.org/Public/Bug/Display.html?id=20677
691
692 - the rubthrough() method can now render onto images with an alpha
693 channel.
694 http://rt.cpan.org/Ticket/Display.html?id=20678
695
696 - the read_multi() method now falls back to calling doing a single
697 image read via the read() method and write_multi() will now fall
698 back to calling write() if a single image is supplied. This means
699 you can simply call the read_multi() or write_multi() functions
700 without having to check if the type is formatted by that method.
701 http://rt.cpan.org/Ticket/Display.html?id=19457
702 http://rt.cpan.org/Ticket/Display.html?id=19458
703
704 - the GIF loop extension can now be written. If you don't have
705 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
706 should upgrade.
707 http://rt.cpan.org/Ticket/Display.html?id=21185
708
709 - getscanline() and setscanline() can now read/write palette index
710 based data from/to the image for paletted images, by setting type to
711 'index'.
712 http://rt.cpan.org/Ticket/Display.html?id=20338
713
714 - we no longer hassle you to disable GIF support
715 http://rt.cpan.org/Ticket/Display.html?id=20687
716
717 - minor documentation fixes
718
719
720Imager 0.53 - 26 Jul 2006
721===========
722
723This is a bugfix release.
724
725Some test code was left in a code path not covered by the test
726suite. A test was added to cover this code path and the test code was
727removed.
728http://rt.cpan.org/Public/Bug/Display.html?id=20705
729
730
731Imager 0.52 - 25 Jul 2006
732===========
733
734This is primarily a feature release, but contains a fair few bug
735fixes, new features:
736
737 - ability to read and write MS Windows ICO and CUR files
738
739 - you can now add file format plugins to support new file formats
740
741 - add POD coverage tests
742
743 - setcolors() and addcolors() now accept color names and so on
744 instead of requiring Imager::Color objects.
745 http://rt.cpan.org/Ticket/Display.html?id=20056
746
747 - flood_fill() can now fill to a specified border color instead of
748 just to the area the same color as the seed.
749 http://rt.cpan.org/Ticket/Display.html?id=19618
750
751
752Bug fixes:
753
754 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
755 calculating the advance width.
756 http://rt.cpan.org/Public/Bug/Display.html?id=20554
757
758 - bounding_box for the T1 driver wasn't including leading and
759 trailing spaces in the bounding box as the other drivers did, it also
760 produced strange results for empty strings or strings containing only
761 spaces
762
763 - when reading CMYK jpeg images they were being transferred to the
764 image object as is, producing a four channel image. It only looked ok
765 due to an old still unfixed Photoshop bug. We now convert from the
766 inverted CMYK that photoshop (and Corel for example) produce into RGB.
767 http://rt.cpan.org/Ticket/Display.html?id=20416
768
769 - reading a CYMK TIFF would result in a 4 channel image, reading any
770 image with more than 4 channels (eg. RGB with 2 alpha channels) would
771 result in an error.
772 http://rt.cpan.org/Ticket/Display.html?id=20415
773
774 - added /usr/local/include to the default include search path, since
775 we were already searching /usr/local/lib for libraries.
776
777And various minor fixes and documentation updates.
778
779
780Imager 0.51 - 23 Apr 2006
