6Bug fixes:
7
8 - release image row and comments memory on all error returns in gif
9 reader
10
11 - handle zero length extensions, previously this would cause a null
12 pointer dereference
13 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.

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

58Bug fixes:
59
60 - correct documentation of default of raw image interleave read
61 parameter
62 https://rt.cpan.org/Ticket/Display.html?id=42074
63
64 - add raw_ prefix to raw read parameters, though the original names
65 still work.
66
67 - fail the read if an invalid raw_interleave parameter is supplied
68
69 - warn if no interleave or raw_interleave parameter is supplied,
70 since the documented default was wrong, and incompatible with the
71 write format
72
73 - for reading raw images, if raw_storechannels > raw_datachannels,
74 set the extra channels in the image to 0
75
cd476e58
TC
76 - when probing for executables like freetype-config, search for .bat
77 and .cmd on MSWin32, as well as .exe.

107
6b22ba84
TC
108 - an optimization skipping 0 src alpha values could cause the
109 rubthrough() to read past the end of a buffer.

111
5c0d0ddf
TC
112 - corrected a reference leak where writing GIFs would leak memory.
113 This could also happen calling to_paletted().
114 Also documented the underlying long existing feature where the
115 colors parameter is filled with the generated color table and added
116 tests for it.

121
c586eb58
TC
122 - add limited tests for Imager::ExtUtils
123
124 - make Imager::ExtUtils->includes use an absolute path, since

126 http://rt.cpan.org/Ticket/Display.html?id=37353
127
6b22ba84
TC
128 - re-arrange the POD for Imager::Font::BBox:
129 - mark total_width(), pos_width(), end_offset() obsolete, since
130 they're mostly for backwards compatibility
131 - group width methods and height methods

TC
135===========
136
137Bug fixes:
138
139 - In some cases when an error occurs reading those parts of a JPEG
140 file after the image the scan-line buffer could be freed a second
141 time. In cases where the the error occured while reading the image
142 data it's possible that the buffer could have leaked.
143 Thanks to Gabriel Vasseur for reporting this and help in tracking
144 it down.
145

TC
146 - the gif_screen_height tag was overriding the screen width and being
147 ignored for the screen height when present.

TC
153This is a bug fix release. This includes a fix for a possible
154security issue.
155
de470892
TC
156Bug fixes:
157
e02d22d2
TC
158 - Possible security issue: The floating point sample path for image
159 based fills had a buffer overflow. This would overwrite the end of
160 a malloc()ed buffer with double precision floats.
161 http://rt.cpan.org/Ticket/Display.html?id=35324
6912d85a 162 CVE-2008-1928
e02d22d2 163
de470892
TC
164 - check that the result of fileno($fh) is defined rather than simply
165 true when read() or write() is supplied with an fh parameter.
166 http://rt.cpan.org/Ticket/Display.html?id=35139
167
168 - i_scale_axis() wasn't checking the result of i_img_new_ch()
169 resulting in a SIGSEGV when attempting to scale an image to a size
170 too large to fit in memory. This is a NULL pointer access issue,
171 not a buffer overflow.
172 Added a check for the failure.
173 scale_calculate() (and hence scale()) will now fail if any of the
174 scale size parameters are a reference.
175 http://rt.cpan.org/Ticket/Display.html?id=35172
176
04f85f63
TC
177 - Regression: filling a greyscale image with a hatch used the wrong
178 color channels from the supplied fg/bg colors.
179 https://rt.cpan.org/Ticket/Display.html?id=35278
180
a256aec5
TC
181 - fixed a related problem for image fills.

33b0ffa6
TC
184===========
185
242d7497
TC
186This release primarily contains changes to improve ease of use -
187rather than you having to convert images to the appropriate number of
188channels, Imager handles it internally. How to handle drawing colors
189and the default combine mode is a thornier problem left for some other
190release.
191
d1555273
TC
192 - the font libraries are now only initialized when needed.
193 http://rt.cpan.org/Ticket/Display.html?id=28825
194
9b1ec2b8
TC
195 - moved the imtoc.perl code into Imager::Preprocess
196
197 - paste() and rubthrough() now adapt the source image data to the
198 destination, so you can now safely paste/rubthrough from greyscale
199 images to color images or back, or from alpha channel images to
200 noalpha channels or back.
201 https://rt.cpan.org/Ticket/Display.html?id=30908
202
203 - rubthrough() now falls back to pasting when the source doesn't have
204 an alpha channel. This effectively treats the source as having a
205 max alpha channel, the right thing to do.
206 http://rt.cpan.org/Ticket/Display.html?id=29944
207
208 - re-worked most of the area filling code to use a common set of
209 functions when filling.
210 Corrected normal combine mode.
211 Rewrote most of the combine modes to match the way the SVG draft
212 defines them with respect to a translucent source and destination.
213 Added tests for translucent source and destination.
214 Added tests to check 8-bit/sample and double/sample combines work
215 similarly.
216 https://rt.cpan.org/Ticket/Display.html?id=29879
217
07d9c639
TC
218 - writing a 2 or 4 channel image to a JPEG file will now write that
219 image as if composited against a background, black by default,
220 overridable with the i_background tag/parameter.

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

TC
225 overridable with the i_background tag/parameter.

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

232
33b0ffa6
TC
233Bug fixes:
234
235 - Imager::Matrix2d->translate() now only requires one of the x or y
236 parameters.
237 http://rt.cpan.org/Ticket/Display.html?id=29937
238
2757bad0
TC
239 - mixing qtype scaling now sets all channels of a pixel to zero if
240 the pixel has zero coverage (zero alpha). This should produce more
241 compressible output files.
242 http://rt.cpan.org/Ticket/Display.html?id=32324
243
3da08517
TC
244 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
245 Noticed when I saw:
246 https://bugzilla.redhat.com/show_bug.cgi?id=166254
247 I'm not changing the #! lines of the sample code, since it's sample
248 code, not intended for installation.
249 http://rt.cpan.org/Ticket/Display.html?id=33408
250
242d7497
TC
251 - some TGA images weren't being detected correctly as TGA images
252 https://rt.cpan.org/Ticket/Display.html?id=32925
253
254 - handling of the left-over bit for 16-bit/pixel TGA images has been
255 changed to match the behaviour of the GIMP. Previously the bit
256 being set was treated as an opaque pixel, but one user reported a
257 problem with loading such an image. I haven't been able to find any
258 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
259 I'll match it's behaviour. See issue 114913 in the GIMP's
260 bugzilla.

TC
266 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
267 to /path under your home directory.
268 http://rt.cpan.org/Ticket/Display.html?id=29484
269
50ff958e
TC
270 - the old dynaload code used Mach API functions to load dynamic
271 libraries on Mac OS X. These APIs have been deprecated in OS X
272 10.5 and were causing some build problems.
273 So henceforth Imager uses the dlopen() family of functions, and you
274 will need version 10.3 or later of OS X.
275
3309187a
TC
276 - added the det() function to the transform2() engine.
277 added the sample quad_to_square.pl

284 gif_left.
285 Thanks to Eleneldil G. Arilou for pointing this out.
286
678a9a65
TC
287 - t/t82inline.t no longer loads B at runtime, to work around a bug
288 in some 5.005_0[45] installations.

TC
302 - major TIFF support re-work
303 http://rt.cpan.org/Ticket/Display.html?id=20329
304
305 - added a C level image interface for accessing samples from 1-32
306 bits, exposed this at the perl level in getsamples()
307
308 - the conv filter now works at floating point precision for high bit
309 images
310
311 - added is_bilevel method to test whether an image should be written as
312 a bilevel image if the image format supports it.
313
314 - added -log-stderr as an Imager import list option
315
316 - added some important types to Imager::APIRef

372 - the SGI RLE compression code could overflow its compression buffer
373 http://rt.cpan.org/Ticket/Display.html?id=30334

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

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

423Bug fixes:
424
425 - in some cases it's possible for giflib/libungif to return color
426 indexes outside the range of colors defined by the image's palette.
427 We now expand the palette to match the indexes used.
428 Thanks to Gabriel Vasseur for reporting this.

430 - fixed various memory leaks that could occur when failing to read png,
431 jpeg, bmp or tga files.
432
b3aa972f
TC
433 - to avoid confusion, channels not present in the image are returned as
434 zero by getscanline(). This has no effect on the C level i_glin()
435 and i_glinf() API functions which continue to not set the unused
436 channels.

438 - the convert() method now returns an image of the same sample size as
439 the source image.

578Imager 0.55 - 16 Dec 2006
579===========
580
581This is primarily a bug fix release.
582
583Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
584
585There is one new feature:
586
587 - the Win32 font driver now supports UTF8 (RT 22166)
588 http://www.cpanforum.com/threads/3276
589 http://rt.cpan.org/Ticket/Display.html?id=22166
590
591Several bugs were fixed:
592
593 - the string() method would not output the string "0"
594 http://rt.cpan.org/Public/Bug/Display.html?id=21770
595
596 - fills.c was failing to compile on Solaris 10 (compiler unknown)
597 http://rt.cpan.org/Public/Bug/Display.html?id=21944
598
599 - the gif_disposal and gif_user_input tags weren't being read from
600 the file correctly
601 http://rt.cpan.org/Public/Bug/Display.html?id=22192
602
603 - gif.c was failing to build under MSVC
604 http://rt.cpan.org/Ticket/Display.html?id=23922
605
606 - in some cases strings passed to the string() method were treated as
607 terminated by NUL (chr 0)
608 http://rt.cpan.org/Public/Bug/Display.html?id=21770
609
610 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
611 that's the default build name for zlib on Win32.
612 http://rt.cpan.org/Ticket/Display.html?id=23064
613
614 - search $Config{incpath} for headers too, which we should have been
615 doing all along.
616
617Win32 font driver fixes:
618
619 - the global descent value from bounding box was the wrong sign
620 http://www.cpanforum.com/threads/3276
621
622 - if the first or last glyph overflowed the left or right side of the
623 advance width they would be clipped
624
625
626Imager 0.54 - 14 Sep 2006
627===========
628
629This is primarily a feature release:
630
631 - a new qtype value 'mixing' has been added to the scale()
632 method. This is faster than 'normal', slower than 'preview'. This
633 is based on the method used by pnmscale, and seems to produce less
634 blurry results than normal.
635 http://rt.cpan.org/Public/Bug/Display.html?id=20677
636
637 - the rubthrough() method can now render onto images with an alpha
638 channel.
639 http://rt.cpan.org/Ticket/Display.html?id=20678
640
641 - the read_multi() method now falls back to calling doing a single
642 image read via the read() method and write_multi() will now fall
643 back to calling write() if a single image is supplied. This means
644 you can simply call the read_multi() or write_multi() functions
645 without having to check if the type is formatted by that method.
646 http://rt.cpan.org/Ticket/Display.html?id=19457
647 http://rt.cpan.org/Ticket/Display.html?id=19458
648
649 - the GIF loop extension can now be written. If you don't have
650 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
651 should upgrade.
652 http://rt.cpan.org/Ticket/Display.html?id=21185
653
654 - getscanline() and setscanline() can now read/write palette index
655 based data from/to the image for paletted images, by setting type to
656 'index'.
657 http://rt.cpan.org/Ticket/Display.html?id=20338
658
659 - we no longer hassle you to disable GIF support
660 http://rt.cpan.org/Ticket/Display.html?id=20687
661
662 - minor documentation fixes
663
664
665Imager 0.53 - 26 Jul 2006
666===========
667
668This is a bugfix release.
669
670Some test code was left in a code path not covered by the test
671suite. A test was added to cover this code path and the test code was
672removed.
673http://rt.cpan.org/Public/Bug/Display.html?id=20705
674
675
676Imager 0.52 - 25 Jul 2006
677===========
678
679This is primarily a feature release, but contains a fair few bug
680fixes, new features:
681
682 - ability to read and write MS Windows ICO and CUR files
683
684 - you can now add file format plugins to support new file formats
685
686 - add POD coverage tests
687
688 - setcolors() and addcolors() now accept color names and so on
689 instead of requiring Imager::Color objects.
690 http://rt.cpan.org/Ticket/Display.html?id=20056
691
692 - flood_fill() can now fill to a specified border color instead of
693 just to the area the same color as the seed.
694 http://rt.cpan.org/Ticket/Display.html?id=19618
695
696
697Bug fixes:
698
699 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
700 calculating the advance width.
701 http://rt.cpan.org/Public/Bug/Display.html?id=20554
702
703 - bounding_box for the T1 driver wasn't including leading and
704 trailing spaces in the bounding box as the other drivers did, it also
705 produced strange results for empty strings or strings containing only
706 spaces
707
708 - when reading CMYK jpeg images they were being transferred to the
709 image object as is, producing a four channel image. It only looked ok
710 due to an old still unfixed Photoshop bug. We now convert from the
711 inverted CMYK that photoshop (and Corel for example) produce into RGB.
712 http://rt.cpan.org/Ticket/Display.html?id=20416
713
714 - reading a CYMK TIFF would result in a 4 channel image, reading any
715 image with more than 4 channels (eg. RGB with 2 alpha channels) would
716 result in an error.
717 http://rt.cpan.org/Ticket/Display.html?id=20415
718
719 - added /usr/local/include to the default include search path, since
720 we were already searching /usr/local/lib for libraries.
721
722And various minor fixes and documentation updates.
723
724
725Imager 0.51 - 23 Apr 2006

742===========

745 or 4 channel image to jpeg or a 2 channel image to tga where the
746 output is an in-memeory buffer.
747 http://rt.cpan.org/Public/Bug/Display.html?id=18397
748
749 - fixes an incorrect pointer parameter in the PNG code
