50Imager 0.71_03 - 5 Dec 2009
51==============

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

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

TC
87 - add the opacity fill type - an adaptor that modifies the opacity of
88 another fill.
89

TC
90Bug fixes:
91
92 - the conv filter now enforces that the sum of the coefficients is
93 non-zero. Also, rather than skipping pixels off the edge off the
94 edge of the image, the closest edge pixel is used. Previously
95 dividing by the zero sum of coefficients could cause invalid
96 results or runtime exceptions.
97 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
98 this bug.

101===========
102
103Bug fixes:
104
105 - release image row and comments memory on all error returns in gif
106 reader
107
108 - handle zero length extensions, previously this would cause a null
109 pointer dereference
110 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.
111

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

TC
144 - re-work most image file test files that require a library into
145 separate library present/not present files to remove stupidly long
146 conditionals
147
148 - don't treat rubthrough() outside the bounds of the target image as
149 an error.

155Bug fixes:
156
157 - correct documentation of default of raw image interleave read
158 parameter
159 https://rt.cpan.org/Ticket/Display.html?id=42074
160
161 - add raw_ prefix to raw read parameters, though the original names
162 still work.
163
164 - fail the read if an invalid raw_interleave parameter is supplied
165
166 - warn if no interleave or raw_interleave parameter is supplied,
167 since the documented default was wrong, and incompatible with the
168 write format
169
170 - for reading raw images, if raw_storechannels > raw_datachannels,
171 set the extra channels in the image to 0
172
cd476e58
TC
173 - when probing for executables like freetype-config, search for .bat
174 and .cmd on MSWin32, as well as .exe.

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

208
5c0d0ddf
TC
209 - corrected a reference leak where writing GIFs would leak memory.
210 This could also happen calling to_paletted().
211 Also documented the underlying long existing feature where the
212 colors parameter is filled with the generated color table and added
213 tests for it.

218
c586eb58
TC
219 - add limited tests for Imager::ExtUtils
220
221 - make Imager::ExtUtils->includes use an absolute path, since
222 a relative path could cause failures using Inline::C.

224
6b22ba84
TC
225 - re-arrange the POD for Imager::Font::BBox:
226 - mark total_width(), pos_width(), end_offset() obsolete, since
227 they're mostly for backwards compatibility
228 - group width methods and height methods

232===========
233
234Bug fixes:
235
236 - In some cases when an error occurs reading those parts of a JPEG
237 file after the image the scan-line buffer could be freed a second
238 time. In cases where the the error occured while reading the image
239 data it's possible that the buffer could have leaked.
240 Thanks to Gabriel Vasseur for reporting this and help in tracking
241 it down.

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

250This is a bug fix release. This includes a fix for a possible

TC
253Bug fixes:
254
e02d22d2
TC
255 - Possible security issue: The floating point sample path for image
256 based fills had a buffer overflow. This would overwrite the end of
257 a malloc()ed buffer with double precision floats.
258 http://rt.cpan.org/Ticket/Display.html?id=35324
6912d85a 259 CVE-2008-1928
e02d22d2 260
de470892
TC
261 - check that the result of fileno($fh) is defined rather than simply
262 true when read() or write() is supplied with an fh parameter.
263 http://rt.cpan.org/Ticket/Display.html?id=35139
264
265 - i_scale_axis() wasn't checking the result of i_img_new_ch()
266 resulting in a SIGSEGV when attempting to scale an image to a size
267 too large to fit in memory. This is a NULL pointer access issue,
268 not a buffer overflow.
269 Added a check for the failure.
270 scale_calculate() (and hence scale()) will now fail if any of the
271 scale size parameters are a reference.
272 http://rt.cpan.org/Ticket/Display.html?id=35172
273

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

TC
281===========
282
242d7497
TC
283This release primarily contains changes to improve ease of use -
284rather than you having to convert images to the appropriate number of
285channels, Imager handles it internally. How to handle drawing colors
286and the default combine mode is a thornier problem left for some other
287release.
288
d1555273
TC
289 - the font libraries are now only initialized when needed.

291
9b1ec2b8
TC
292 - moved the imtoc.perl code into Imager::Preprocess
293
294 - paste() and rubthrough() now adapt the source image data to the
295 destination, so you can now safely paste/rubthrough from greyscale
296 images to color images or back, or from alpha channel images to
297 noalpha channels or back.
298 https://rt.cpan.org/Ticket/Display.html?id=30908
299
300 - rubthrough() now falls back to pasting when the source doesn't have
301 an alpha channel. This effectively treats the source as having a
302 max alpha channel, the right thing to do.
303 http://rt.cpan.org/Ticket/Display.html?id=29944
304
305 - re-worked most of the area filling code to use a common set of
306 functions when filling.
307 Corrected normal combine mode.
308 Rewrote most of the combine modes to match the way the SVG draft
309 defines them with respect to a translucent source and destination.
310 Added tests for translucent source and destination.
311 Added tests to check 8-bit/sample and double/sample combines work
312 similarly.

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

333 parameters.
334 http://rt.cpan.org/Ticket/Display.html?id=29937
335

TC
336 - mixing qtype scaling now sets all channels of a pixel to zero if
337 the pixel has zero coverage (zero alpha). This should produce more
338 compressible output files.
339 http://rt.cpan.org/Ticket/Display.html?id=32324
340

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

TC
348 - some TGA images weren't being detected correctly as TGA images
349 https://rt.cpan.org/Ticket/Display.html?id=32925
350
351 - handling of the left-over bit for 16-bit/pixel TGA images has been
352 changed to match the behaviour of the GIMP. Previously the bit
353 being set was treated as an opaque pixel, but one user reported a
354 problem with loading such an image. I haven't been able to find any
355 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
356 I'll match it's behaviour. See issue 114913 in the GIMP's
357 bugzilla.

TC
367 - the old dynaload code used Mach API functions to load dynamic
368 libraries on Mac OS X. These APIs have been deprecated in OS X
369 10.5 and were causing some build problems.
370 So henceforth Imager uses the dlopen() family of functions, and you
371 will need version 10.3 or later of OS X.

403 bits, exposed this at the perl level in getsamples()
404
405 - the conv filter now works at floating point precision for high bit
406 images

675Imager 0.55 - 16 Dec 2006
676===========
677
678This is primarily a bug fix release.
679
680Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
681
682There is one new feature:
683
684 - the Win32 font driver now supports UTF8 (RT 22166)
685 http://www.cpanforum.com/threads/3276
686 http://rt.cpan.org/Ticket/Display.html?id=22166
687
688Several bugs were fixed:
689
690 - the string() method would not output the string "0"
691 http://rt.cpan.org/Public/Bug/Display.html?id=21770
692
693 - fills.c was failing to compile on Solaris 10 (compiler unknown)
694 http://rt.cpan.org/Public/Bug/Display.html?id=21944
695
696 - the gif_disposal and gif_user_input tags weren't being read from
697 the file correctly
698 http://rt.cpan.org/Public/Bug/Display.html?id=22192
699
700 - gif.c was failing to build under MSVC
701 http://rt.cpan.org/Ticket/Display.html?id=23922
702
703 - in some cases strings passed to the string() method were treated as
704 terminated by NUL (chr 0)
705 http://rt.cpan.org/Public/Bug/Display.html?id=21770
706
707 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
708 that's the default build name for zlib on Win32.
709 http://rt.cpan.org/Ticket/Display.html?id=23064
710
711 - search $Config{incpath} for headers too, which we should have been
712 doing all along.
713
714Win32 font driver fixes:
715
716 - the global descent value from bounding box was the wrong sign
717 http://www.cpanforum.com/threads/3276
718
719 - if the first or last glyph overflowed the left or right side of the
720 advance width they would be clipped
721
722
723Imager 0.54 - 14 Sep 2006
724===========
725
726This is primarily a feature release:
727
728 - a new qtype value 'mixing' has been added to the scale()
729 method. This is faster than 'normal', slower than 'preview'. This
730 is based on the method used by pnmscale, and seems to produce less
731 blurry results than normal.
732 http://rt.cpan.org/Public/Bug/Display.html?id=20677
733
734 - the rubthrough() method can now render onto images with an alpha
735 channel.
736 http://rt.cpan.org/Ticket/Display.html?id=20678
737
738 - the read_multi() method now falls back to calling doing a single
739 image read via the read() method and write_multi() will now fall
740 back to calling write() if a single image is supplied. This means
741 you can simply call the read_multi() or write_multi() functions
742 without having to check if the type is formatted by that method.
743 http://rt.cpan.org/Ticket/Display.html?id=19457
744 http://rt.cpan.org/Ticket/Display.html?id=19458
745
746 - the GIF loop extension can now be written. If you don't have
747 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
748 should upgrade.
749 http://rt.cpan.org/Ticket/Display.html?id=21185
750
751 - getscanline() and setscanline() can now read/write palette index
752 based data from/to the image for paletted images, by setting type to
753 'index'.
754 http://rt.cpan.org/Ticket/Display.html?id=20338
755
756 - we no longer hassle you to disable GIF support
757 http://rt.cpan.org/Ticket/Display.html?id=20687
758
759 - minor documentation fixes
760
761
762Imager 0.53 - 26 Jul 2006
763===========
764
765This is a bugfix release.
766
767Some test code was left in a code path not covered by the test
768suite. A test was added to cover this code path and the test code was
769removed.
770http://rt.cpan.org/Public/Bug/Display.html?id=20705
771
772
773Imager 0.52 - 25 Jul 2006
774===========
775
776This is primarily a feature release, but contains a fair few bug
777fixes, new features:
778
779 - ability to read and write MS Windows ICO and CUR files
780
781 - you can now add file format plugins to support new file formats
782
783 - add POD coverage tests
784
785 - setcolors() and addcolors() now accept color names and so on
786 instead of requiring Imager::Color objects.
787 http://rt.cpan.org/Ticket/Display.html?id=20056
788
789 - flood_fill() can now fill to a specified border color instead of
790 just to the area the same color as the seed.
791 http://rt.cpan.org/Ticket/Display.html?id=19618
792
793
794Bug fixes:
795
796 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
797 calculating the advance width.
798 http://rt.cpan.org/Public/Bug/Display.html?id=20554
799
800 - bounding_box for the T1 driver wasn't including leading and
801 trailing spaces in the bounding box as the other drivers did, it also
802 produced strange results for empty strings or strings containing only
803 spaces
804
805 - when reading CMYK jpeg images they were being transferred to the
806 image object as is, producing a four channel image. It only looked ok
807 due to an old still unfixed Photoshop bug. We now convert from the
808 inverted CMYK that photoshop (and Corel for example) produce into RGB.
809 http://rt.cpan.org/Ticket/Display.html?id=20416
810
811 - reading a CYMK TIFF would result in a 4 channel image, reading any
812 image with more than 4 channels (eg. RGB with 2 alpha channels) would
813 result in an error.
814 http://rt.cpan.org/Ticket/Display.html?id=20415
815
816 - added /usr/local/include to the default include search path, since
817 we were already searching /usr/local/lib for libraries.
818
819And various minor fixes and documentation updates.
820
821
822Imager 0.51 - 23 Apr 2006
