6Bug fixes:
7
8 - use scanline oriented operations to flip images instead of pixel
9 operations
10 https://rt.cpan.org/Ticket/Display.html?id=39278
11
12 - use double/sample operations to flip large sample images instead of
13 8-bit sample operations.

ffddd407
TC
19 - prevent double-frees when someone creates Imager objects and then
20 creates a thread. Note: this just handles some simple cases,
21 Imager doesn't support perl threads, and isn't likely to.

TC
27 - add the opacity fill type - an adaptor that modifies the opacity of
28 another fill.
29
6a3cbaef
TC
30Bug fixes:
31
32 - the conv filter now enforces that the sum of the coefficients is
33 non-zero. Also, rather than skipping pixels off the edge off the
34 edge of the image, the closest edge pixel is used. Previously
35 dividing by the zero sum of coefficients could cause invalid
36 results or runtime exceptions.
37 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
38 this bug.

TC
41===========
42
43Bug fixes:
44
45 - release image row and comments memory on all error returns in gif
46 reader
47
48 - handle zero length extensions, previously this would cause a null
49 pointer dereference
50 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.
51
b3afeed5
TC
52 - an integer division meant that preview scaling to below 1 pixel
53 wide or high (which isn't too useful anyway) was calculating using
54 NaNs on most platforms, and causing an exception on others.
55 Thanks to David Cantrell for producing a backtrace of the crash on
56 his Alpha-NetBSD CPAN test box which made it possible to track this
57 down.

64 - broken test fix - was attempting to call a function skip_all, when
65 that should be a parameter to plan().
66

84 - re-work most image file test files that require a library into
85 separate library present/not present files to remove stupidly long
86 conditionals
87

95Bug fixes:
96
97 - correct documentation of default of raw image interleave read
98 parameter
99 https://rt.cpan.org/Ticket/Display.html?id=42074
100
101 - add raw_ prefix to raw read parameters, though the original names
102 still work.
103
104 - fail the read if an invalid raw_interleave parameter is supplied
105
106 - warn if no interleave or raw_interleave parameter is supplied,
107 since the documented default was wrong, and incompatible with the
108 write format
109
110 - for reading raw images, if raw_storechannels > raw_datachannels,
111 set the extra channels in the image to 0
112
cd476e58
TC
113 - when probing for executables like freetype-config, search for .bat
114 and .cmd on MSWin32, as well as .exe.

143Bug fixes:
144
6b22ba84
TC
145 - an optimization skipping 0 src alpha values could cause the
146 rubthrough() to read past the end of a buffer.

148
5c0d0ddf
TC
149 - corrected a reference leak where writing GIFs would leak memory.
150 This could also happen calling to_paletted().
151 Also documented the underlying long existing feature where the
152 colors parameter is filled with the generated color table and added
153 tests for it.

158
c586eb58
TC
159 - add limited tests for Imager::ExtUtils
160
161 - make Imager::ExtUtils->includes use an absolute path, since
162 a relative path could cause failures using Inline::C.
163 http://rt.cpan.org/Ticket/Display.html?id=37353
164
6b22ba84
TC
165 - re-arrange the POD for Imager::Font::BBox:
166 - mark total_width(), pos_width(), end_offset() obsolete, since
167 they're mostly for backwards compatibility
168 - group width methods and height methods

546ea21c
TC
172===========
173
174Bug fixes:
175
176 - In some cases when an error occurs reading those parts of a JPEG
177 file after the image the scan-line buffer could be freed a second
178 time. In cases where the the error occured while reading the image
179 data it's possible that the buffer could have leaked.
180 Thanks to Gabriel Vasseur for reporting this and help in tracking
181 it down.
182
43b2b326
TC
183 - the gif_screen_height tag was overriding the screen width and being
184 ignored for the screen height when present.

TC
190This is a bug fix release. This includes a fix for a possible
191security issue.
192
de470892
TC
193Bug fixes:
194
e02d22d2
TC
195 - Possible security issue: The floating point sample path for image
196 based fills had a buffer overflow. This would overwrite the end of
197 a malloc()ed buffer with double precision floats.
198 http://rt.cpan.org/Ticket/Display.html?id=35324
6912d85a 199 CVE-2008-1928
e02d22d2 200
de470892
TC
201 - check that the result of fileno($fh) is defined rather than simply
202 true when read() or write() is supplied with an fh parameter.
203 http://rt.cpan.org/Ticket/Display.html?id=35139
204
205 - i_scale_axis() wasn't checking the result of i_img_new_ch()
206 resulting in a SIGSEGV when attempting to scale an image to a size
207 too large to fit in memory. This is a NULL pointer access issue,
208 not a buffer overflow.
209 Added a check for the failure.
210 scale_calculate() (and hence scale()) will now fail if any of the
211 scale size parameters are a reference.
212 http://rt.cpan.org/Ticket/Display.html?id=35172
213
04f85f63
TC
214 - Regression: filling a greyscale image with a hatch used the wrong
215 color channels from the supplied fg/bg colors.
216 https://rt.cpan.org/Ticket/Display.html?id=35278
217
a256aec5
TC
218 - fixed a related problem for image fills.

33b0ffa6
TC
221===========
222
242d7497
TC
223This release primarily contains changes to improve ease of use -
224rather than you having to convert images to the appropriate number of
225channels, Imager handles it internally. How to handle drawing colors
226and the default combine mode is a thornier problem left for some other
227release.
228
d1555273
TC
229 - the font libraries are now only initialized when needed.
230 http://rt.cpan.org/Ticket/Display.html?id=28825
231
9b1ec2b8
TC
232 - moved the imtoc.perl code into Imager::Preprocess
233
234 - paste() and rubthrough() now adapt the source image data to the
235 destination, so you can now safely paste/rubthrough from greyscale
236 images to color images or back, or from alpha channel images to
237 noalpha channels or back.
238 https://rt.cpan.org/Ticket/Display.html?id=30908
239
240 - rubthrough() now falls back to pasting when the source doesn't have
241 an alpha channel. This effectively treats the source as having a
242 max alpha channel, the right thing to do.
243 http://rt.cpan.org/Ticket/Display.html?id=29944
244
245 - re-worked most of the area filling code to use a common set of
246 functions when filling.
247 Corrected normal combine mode.
248 Rewrote most of the combine modes to match the way the SVG draft
249 defines them with respect to a translucent source and destination.
250 Added tests for translucent source and destination.
251 Added tests to check 8-bit/sample and double/sample combines work
252 similarly.

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

260 - writing a 2 or 4 channel image to a PGM/PPM file will now write
261 that image as if composited against a background, black by default,

TC
270Bug fixes:
271
272 - Imager::Matrix2d->translate() now only requires one of the x or y
273 parameters.
274 http://rt.cpan.org/Ticket/Display.html?id=29937
275
2757bad0
TC
276 - mixing qtype scaling now sets all channels of a pixel to zero if
277 the pixel has zero coverage (zero alpha). This should produce more
278 compressible output files.
279 http://rt.cpan.org/Ticket/Display.html?id=32324
280
3da08517
TC
281 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
282 Noticed when I saw:
283 https://bugzilla.redhat.com/show_bug.cgi?id=166254
284 I'm not changing the #! lines of the sample code, since it's sample
285 code, not intended for installation.
286 http://rt.cpan.org/Ticket/Display.html?id=33408
287
242d7497
TC
288 - some TGA images weren't being detected correctly as TGA images
289 https://rt.cpan.org/Ticket/Display.html?id=32925
290
291 - handling of the left-over bit for 16-bit/pixel TGA images has been
292 changed to match the behaviour of the GIMP. Previously the bit
293 being set was treated as an opaque pixel, but one user reported a
294 problem with loading such an image. I haven't been able to find any
295 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
296 I'll match it's behaviour. See issue 114913 in the GIMP's
297 bugzilla.

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

306
50ff958e
TC
307 - the old dynaload code used Mach API functions to load dynamic
308 libraries on Mac OS X. These APIs have been deprecated in OS X
309 10.5 and were causing some build problems.
310 So henceforth Imager uses the dlopen() family of functions, and you
311 will need version 10.3 or later of OS X.
312
3309187a
TC
313 - added the det() function to the transform2() engine.

341
342 - added a C level image interface for accessing samples from 1-32
343 bits, exposed this at the perl level in getsamples()
344
345 - the conv filter now works at floating point precision for high bit
346 images
347

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

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

470 - to avoid confusion, channels not present in the image are returned as

473 channels.

615Imager 0.55 - 16 Dec 2006
616===========
617
618This is primarily a bug fix release.
619
620Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
621
622There is one new feature:
623
624 - the Win32 font driver now supports UTF8 (RT 22166)
625 http://www.cpanforum.com/threads/3276
626 http://rt.cpan.org/Ticket/Display.html?id=22166
627
628Several bugs were fixed:
629
630 - the string() method would not output the string "0"
631 http://rt.cpan.org/Public/Bug/Display.html?id=21770
632
633 - fills.c was failing to compile on Solaris 10 (compiler unknown)
634 http://rt.cpan.org/Public/Bug/Display.html?id=21944
635
636 - the gif_disposal and gif_user_input tags weren't being read from
637 the file correctly
638 http://rt.cpan.org/Public/Bug/Display.html?id=22192
639
640 - gif.c was failing to build under MSVC
641 http://rt.cpan.org/Ticket/Display.html?id=23922
642
643 - in some cases strings passed to the string() method were treated as
644 terminated by NUL (chr 0)
645 http://rt.cpan.org/Public/Bug/Display.html?id=21770
646
647 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
648 that's the default build name for zlib on Win32.
649 http://rt.cpan.org/Ticket/Display.html?id=23064
650
651 - search $Config{incpath} for headers too, which we should have been
652 doing all along.
653
654Win32 font driver fixes:
655
656 - the global descent value from bounding box was the wrong sign
657 http://www.cpanforum.com/threads/3276
658
659 - if the first or last glyph overflowed the left or right side of the
660 advance width they would be clipped
661
662
663Imager 0.54 - 14 Sep 2006
664===========
665
666This is primarily a feature release:
667
668 - a new qtype value 'mixing' has been added to the scale()
669 method. This is faster than 'normal', slower than 'preview'. This
670 is based on the method used by pnmscale, and seems to produce less
671 blurry results than normal.
672 http://rt.cpan.org/Public/Bug/Display.html?id=20677
673
674 - the rubthrough() method can now render onto images with an alpha
675 channel.
676 http://rt.cpan.org/Ticket/Display.html?id=20678
677
678 - the read_multi() method now falls back to calling doing a single
679 image read via the read() method and write_multi() will now fall
680 back to calling write() if a single image is supplied. This means
681 you can simply call the read_multi() or write_multi() functions
682 without having to check if the type is formatted by that method.
683 http://rt.cpan.org/Ticket/Display.html?id=19457
684 http://rt.cpan.org/Ticket/Display.html?id=19458
685
686 - the GIF loop extension can now be written. If you don't have
687 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
688 should upgrade.
689 http://rt.cpan.org/Ticket/Display.html?id=21185
690
691 - getscanline() and setscanline() can now read/write palette index
692 based data from/to the image for paletted images, by setting type to
693 'index'.
694 http://rt.cpan.org/Ticket/Display.html?id=20338
695
696 - we no longer hassle you to disable GIF support
697 http://rt.cpan.org/Ticket/Display.html?id=20687
698
699 - minor documentation fixes
700
701
702Imager 0.53 - 26 Jul 2006
703===========
704
705This is a bugfix release.
706
707Some test code was left in a code path not covered by the test
708suite. A test was added to cover this code path and the test code was
709removed.
710http://rt.cpan.org/Public/Bug/Display.html?id=20705
711
712
713Imager 0.52 - 25 Jul 2006
714===========
715
716This is primarily a feature release, but contains a fair few bug
717fixes, new features:
718
719 - ability to read and write MS Windows ICO and CUR files
720
721 - you can now add file format plugins to support new file formats
722
723 - add POD coverage tests
724
725 - setcolors() and addcolors() now accept color names and so on
726 instead of requiring Imager::Color objects.
727 http://rt.cpan.org/Ticket/Display.html?id=20056
728
729 - flood_fill() can now fill to a specified border color instead of
730 just to the area the same color as the seed.
731 http://rt.cpan.org/Ticket/Display.html?id=19618
732
733
734Bug fixes:
735
736 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
737 calculating the advance width.
738 http://rt.cpan.org/Public/Bug/Display.html?id=20554
739
740 - bounding_box for the T1 driver wasn't including leading and
741 trailing spaces in the bounding box as the other drivers did, it also
742 produced strange results for empty strings or strings containing only
743 spaces
744
745 - when reading CMYK jpeg images they were being transferred to the
746 image object as is, producing a four channel image. It only looked ok
747 due to an old still unfixed Photoshop bug. We now convert from the
748 inverted CMYK that photoshop (and Corel for example) produce into RGB.
749 http://rt.cpan.org/Ticket/Display.html?id=20416
750
751 - reading a CYMK TIFF would result in a 4 channel image, reading any
752 image with more than 4 channels (eg. RGB with 2 alpha channels) would
753 result in an error.
754 http://rt.cpan.org/Ticket/Display.html?id=20415
755
756 - added /usr/local/include to the default include search path, since
757 we were already searching /usr/local/lib for libraries.
758
759And various minor fixes and documentation updates.
760
761
762Imager 0.51 - 23 Apr 2006

768

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