6 - further adjust the threads test so it only performs the tests on
7 perls where it's expected to work, and only if the threads module
8 can be loaded.

20
21 - use scanline oriented operations to flip images instead of pixel
22 operations
23 https://rt.cpan.org/Ticket/Display.html?id=39278
24
25 - use double/sample operations to flip large sample images instead of
26 8-bit sample operations.

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

TC
40 - add the opacity fill type - an adaptor that modifies the opacity of
41 another fill.
42
6a3cbaef
TC
43Bug fixes:
44
45 - the conv filter now enforces that the sum of the coefficients is
46 non-zero. Also, rather than skipping pixels off the edge off the
47 edge of the image, the closest edge pixel is used. Previously
48 dividing by the zero sum of coefficients could cause invalid
49 results or runtime exceptions.
50 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
51 this bug.

56Bug fixes:
57
58 - release image row and comments memory on all error returns in gif
59 reader
60
61 - handle zero length extensions, previously this would cause a null
62 pointer dereference
63 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.
64

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

110 - correct documentation of default of raw image interleave read
111 parameter
112 https://rt.cpan.org/Ticket/Display.html?id=42074
113
114 - add raw_ prefix to raw read parameters, though the original names
115 still work.
116
117 - fail the read if an invalid raw_interleave parameter is supplied
118
119 - warn if no interleave or raw_interleave parameter is supplied,
120 since the documented default was wrong, and incompatible with the
121 write format
122
123 - for reading raw images, if raw_storechannels > raw_datachannels,
124 set the extra channels in the image to 0
125
cd476e58

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

161
5c0d0ddf
TC
162 - corrected a reference leak where writing GIFs would leak memory.
163 This could also happen calling to_paletted().
164 Also documented the underlying long existing feature where the
165 colors parameter is filled with the generated color table and added
166 tests for it.

c586eb58
TC
172 - add limited tests for Imager::ExtUtils
173
174 - make Imager::ExtUtils->includes use an absolute path, since

177
6b22ba84
TC
178 - re-arrange the POD for Imager::Font::BBox:
179 - mark total_width(), pos_width(), end_offset() obsolete, since
180 they're mostly for backwards compatibility
181 - group width methods and height methods

185===========
186
187Bug fixes:
188
189 - In some cases when an error occurs reading those parts of a JPEG
190 file after the image the scan-line buffer could be freed a second
191 time. In cases where the the error occured while reading the image
192 data it's possible that the buffer could have leaked.
193 Thanks to Gabriel Vasseur for reporting this and help in tracking
194 it down.

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

TC
203This is a bug fix release. This includes a fix for a possible
204security issue.

TC
206Bug fixes:
207
e02d22d2
TC
208 - Possible security issue: The floating point sample path for image
209 based fills had a buffer overflow. This would overwrite the end of
210 a malloc()ed buffer with double precision floats.
211 http://rt.cpan.org/Ticket/Display.html?id=35324
6912d85a 212 CVE-2008-1928
e02d22d2 213
de470892
TC
214 - check that the result of fileno($fh) is defined rather than simply
215 true when read() or write() is supplied with an fh parameter.
216 http://rt.cpan.org/Ticket/Display.html?id=35139
217
218 - i_scale_axis() wasn't checking the result of i_img_new_ch()
219 resulting in a SIGSEGV when attempting to scale an image to a size
220 too large to fit in memory. This is a NULL pointer access issue,
221 not a buffer overflow.
222 Added a check for the failure.
223 scale_calculate() (and hence scale()) will now fail if any of the
224 scale size parameters are a reference.
225 http://rt.cpan.org/Ticket/Display.html?id=35172
226
04f85f63
TC
227 - Regression: filling a greyscale image with a hatch used the wrong
228 color channels from the supplied fg/bg colors.
229 https://rt.cpan.org/Ticket/Display.html?id=35278
230
a256aec5
TC
231 - fixed a related problem for image fills.

TC
234===========
235
242d7497
TC
236This release primarily contains changes to improve ease of use -
237rather than you having to convert images to the appropriate number of
238channels, Imager handles it internally. How to handle drawing colors
239and the default combine mode is a thornier problem left for some other
240release.
241
d1555273
TC
242 - the font libraries are now only initialized when needed.
243 http://rt.cpan.org/Ticket/Display.html?id=28825
244
9b1ec2b8
TC
245 - moved the imtoc.perl code into Imager::Preprocess
246
247 - paste() and rubthrough() now adapt the source image data to the
248 destination, so you can now safely paste/rubthrough from greyscale
249 images to color images or back, or from alpha channel images to
250 noalpha channels or back.
251 https://rt.cpan.org/Ticket/Display.html?id=30908
252
253 - rubthrough() now falls back to pasting when the source doesn't have
254 an alpha channel. This effectively treats the source as having a
255 max alpha channel, the right thing to do.
256 http://rt.cpan.org/Ticket/Display.html?id=29944
257
258 - re-worked most of the area filling code to use a common set of
259 functions when filling.
260 Corrected normal combine mode.
261 Rewrote most of the combine modes to match the way the SVG draft
262 defines them with respect to a translucent source and destination.
263 Added tests for translucent source and destination.
264 Added tests to check 8-bit/sample and double/sample combines work
265 similarly.

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

283Bug fixes:
284
285 - Imager::Matrix2d->translate() now only requires one of the x or y
286 parameters.
287 http://rt.cpan.org/Ticket/Display.html?id=29937
288
2757bad0
TC
289 - mixing qtype scaling now sets all channels of a pixel to zero if
290 the pixel has zero coverage (zero alpha). This should produce more
291 compressible output files.
292 http://rt.cpan.org/Ticket/Display.html?id=32324
293
3da08517
TC
294 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
295 Noticed when I saw:
296 https://bugzilla.redhat.com/show_bug.cgi?id=166254
297 I'm not changing the #! lines of the sample code, since it's sample
298 code, not intended for installation.

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

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

TC
320 - the old dynaload code used Mach API functions to load dynamic
321 libraries on Mac OS X. These APIs have been deprecated in OS X
322 10.5 and were causing some build problems.
323 So henceforth Imager uses the dlopen() family of functions, and you
324 will need version 10.3 or later of OS X.
325

356 bits, exposed this at the perl level in getsamples()
357
358 - the conv filter now works at floating point precision for high bit
359 images

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

462 - applied Gabriel Vasseur's patch
463 added documentation, further tests, and support for greyscale images
464 Obviously problems are my fault :)

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

473Bug fixes:
474
475 - in some cases it's possible for giflib/libungif to return color
476 indexes outside the range of colors defined by the image's palette.
477 We now expand the palette to match the indexes used.
478 Thanks to Gabriel Vasseur for reporting this.

TC
480 - fixed various memory leaks that could occur when failing to read png,
481 jpeg, bmp or tga files.
482

TC
483 - to avoid confusion, channels not present in the image are returned as
484 zero by getscanline(). This has no effect on the C level i_glin()
485 and i_glinf() API functions which continue to not set the unused
486 channels.
487

TC
488 - the convert() method now returns an image of the same sample size as
489 the source image.

492 - remove repeated text in Imager::Files
493 http://rt.cpan.org/Ticket/Display.html?id=27589
494

496 image, but return a new image.

556 - reworked library probing, we can now set more than one probe
557 function for a library. Disabled the default (non-freetype-config)
558 library probe and added an extra probe function that searches for
559 both ft2build.h and whatever it includes, and adds -I as needed.
560 Hopefully this will fix build problems like

628Imager 0.55 - 16 Dec 2006
629===========
630
631This is primarily a bug fix release.
632
633Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
634
635There is one new feature:
636
637 - the Win32 font driver now supports UTF8 (RT 22166)
638 http://www.cpanforum.com/threads/3276
639 http://rt.cpan.org/Ticket/Display.html?id=22166
640
641Several bugs were fixed:
642
643 - the string() method would not output the string "0"
644 http://rt.cpan.org/Public/Bug/Display.html?id=21770
645
646 - fills.c was failing to compile on Solaris 10 (compiler unknown)
647 http://rt.cpan.org/Public/Bug/Display.html?id=21944
648
649 - the gif_disposal and gif_user_input tags weren't being read from
650 the file correctly
651 http://rt.cpan.org/Public/Bug/Display.html?id=22192
652
653 - gif.c was failing to build under MSVC
654 http://rt.cpan.org/Ticket/Display.html?id=23922
655
656 - in some cases strings passed to the string() method were treated as
657 terminated by NUL (chr 0)
658 http://rt.cpan.org/Public/Bug/Display.html?id=21770
659
660 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
661 that's the default build name for zlib on Win32.
662 http://rt.cpan.org/Ticket/Display.html?id=23064
663
664 - search $Config{incpath} for headers too, which we should have been
665 doing all along.
666
667Win32 font driver fixes:
668
669 - the global descent value from bounding box was the wrong sign
670 http://www.cpanforum.com/threads/3276
671
672 - if the first or last glyph overflowed the left or right side of the
673 advance width they would be clipped
674
675
676Imager 0.54 - 14 Sep 2006
677===========
678
679This is primarily a feature release:
680
681 - a new qtype value 'mixing' has been added to the scale()
682 method. This is faster than 'normal', slower than 'preview'. This
683 is based on the method used by pnmscale, and seems to produce less
684 blurry results than normal.
685 http://rt.cpan.org/Public/Bug/Display.html?id=20677
686
687 - the rubthrough() method can now render onto images with an alpha
688 channel.
689 http://rt.cpan.org/Ticket/Display.html?id=20678
690
691 - the read_multi() method now falls back to calling doing a single
692 image read via the read() method and write_multi() will now fall
693 back to calling write() if a single image is supplied. This means
694 you can simply call the read_multi() or write_multi() functions
695 without having to check if the type is formatted by that method.
696 http://rt.cpan.org/Ticket/Display.html?id=19457
697 http://rt.cpan.org/Ticket/Display.html?id=19458
698
699 - the GIF loop extension can now be written. If you don't have
700 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
701 should upgrade.
702 http://rt.cpan.org/Ticket/Display.html?id=21185
703
704 - getscanline() and setscanline() can now read/write palette index
705 based data from/to the image for paletted images, by setting type to
706 'index'.
707 http://rt.cpan.org/Ticket/Display.html?id=20338
708
709 - we no longer hassle you to disable GIF support
710 http://rt.cpan.org/Ticket/Display.html?id=20687
711
712 - minor documentation fixes
713
714
715Imager 0.53 - 26 Jul 2006
716===========
717
718This is a bugfix release.
719
720Some test code was left in a code path not covered by the test
721suite. A test was added to cover this code path and the test code was
722removed.
723http://rt.cpan.org/Public/Bug/Display.html?id=20705
724
725
726Imager 0.52 - 25 Jul 2006
727===========
728
729This is primarily a feature release, but contains a fair few bug
730fixes, new features:
731
732 - ability to read and write MS Windows ICO and CUR files
733
734 - you can now add file format plugins to support new file formats
735
736 - add POD coverage tests
737
738 - setcolors() and addcolors() now accept color names and so on
739 instead of requiring Imager::Color objects.
740 http://rt.cpan.org/Ticket/Display.html?id=20056
741
742 - flood_fill() can now fill to a specified border color instead of
743 just to the area the same color as the seed.
744 http://rt.cpan.org/Ticket/Display.html?id=19618
745
746
747Bug fixes:
748
749 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
750 calculating the advance width.
751 http://rt.cpan.org/Public/Bug/Display.html?id=20554
752
753 - bounding_box for the T1 driver wasn't including leading and
754 trailing spaces in the bounding box as the other drivers did, it also
755 produced strange results for empty strings or strings containing only
756 spaces
757
758 - when reading CMYK jpeg images they were being transferred to the
759 image object as is, producing a four channel image. It only looked ok
760 due to an old still unfixed Photoshop bug. We now convert from the
761 inverted CMYK that photoshop (and Corel for example) produce into RGB.
762 http://rt.cpan.org/Ticket/Display.html?id=20416
763
764 - reading a CYMK TIFF would result in a 4 channel image, reading any
765 image with more than 4 channels (eg. RGB with 2 alpha channels) would
766 result in an error.
767 http://rt.cpan.org/Ticket/Display.html?id=20415
768
769 - added /usr/local/include to the default include search path, since
770 we were already searching /usr/local/lib for libraries.
771
772And various minor fixes and documentation updates.
773
774
775Imager 0.51 - 23 Apr 2006

781
782 - fix mis-processing of the src_maxx and src_maxy parameters of the
783 paste() method
784 http://rt.cpan.org/Public/Bug/Display.html?id=18712
785
786 - fix a problem in Imager's "smart" handling of the color parameter
787 to various methods.
788 http://rt.cpan.org/Public/Bug/Display.html?id=18561
789
790
791Imager 0.50 - 29 Mar 2006
792===========
793
794 - CRITICAL: fixes a segmentation fault from attempting to write a 2
795 or 4 channel image to jpeg or a 2 channel image to tga where the
796 output is an in-memeory buffer.
797 http://rt.cpan.org/Public/Bug/Display.html?id=18397
798
799 - fixes an incorrect pointer parameter in the PNG code
