53 - correct documentation of default of raw image interleave read
54 parameter
55 https://rt.cpan.org/Ticket/Display.html?id=42074
56
57 - add raw_ prefix to raw read parameters, though the original names
58 still work.
59
60 - fail the read if an invalid raw_interleave parameter is supplied
61
62 - warn if no interleave or raw_interleave parameter is supplied,
63 since the documented default was wrong, and incompatible with the
64 write format
65
66 - for reading raw images, if raw_storechannels > raw_datachannels,
67 set the extra channels in the image to 0
68
cd476e58
TC
69 - when probing for executables like freetype-config, search for .bat

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

104
5c0d0ddf
TC
105 - corrected a reference leak where writing GIFs would leak memory.
106 This could also happen calling to_paletted().
107 Also documented the underlying long existing feature where the
108 colors parameter is filled with the generated color table and added
109 tests for it.

c586eb58
TC
115 - add limited tests for Imager::ExtUtils
116
117 - make Imager::ExtUtils->includes use an absolute path, since

120
6b22ba84
TC
121 - re-arrange the POD for Imager::Font::BBox:
122 - mark total_width(), pos_width(), end_offset() obsolete, since
123 they're mostly for backwards compatibility
124 - group width methods and height methods

129
130Bug fixes:
131
132 - In some cases when an error occurs reading those parts of a JPEG
133 file after the image the scan-line buffer could be freed a second
134 time. In cases where the the error occured while reading the image
135 data it's possible that the buffer could have leaked.
136 Thanks to Gabriel Vasseur for reporting this and help in tracking
137 it down.

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

TC
146This is a bug fix release. This includes a fix for a possible
147security issue.
148
de470892
TC
149Bug fixes:
150
e02d22d2
TC
151 - Possible security issue: The floating point sample path for image
152 based fills had a buffer overflow. This would overwrite the end of
153 a malloc()ed buffer with double precision floats.
154 http://rt.cpan.org/Ticket/Display.html?id=35324
6912d85a 155 CVE-2008-1928
e02d22d2 156
de470892
TC
157 - check that the result of fileno($fh) is defined rather than simply
158 true when read() or write() is supplied with an fh parameter.
159 http://rt.cpan.org/Ticket/Display.html?id=35139
160
161 - i_scale_axis() wasn't checking the result of i_img_new_ch()
162 resulting in a SIGSEGV when attempting to scale an image to a size
163 too large to fit in memory. This is a NULL pointer access issue,
164 not a buffer overflow.
165 Added a check for the failure.
166 scale_calculate() (and hence scale()) will now fail if any of the
167 scale size parameters are a reference.
168 http://rt.cpan.org/Ticket/Display.html?id=35172
169
04f85f63
TC
170 - Regression: filling a greyscale image with a hatch used the wrong
171 color channels from the supplied fg/bg colors.
172 https://rt.cpan.org/Ticket/Display.html?id=35278
173
a256aec5
TC
174 - fixed a related problem for image fills.

33b0ffa6
TC
177===========
178
242d7497
TC
179This release primarily contains changes to improve ease of use -
180rather than you having to convert images to the appropriate number of
181channels, Imager handles it internally. How to handle drawing colors
182and the default combine mode is a thornier problem left for some other
183release.
184
d1555273
TC
185 - the font libraries are now only initialized when needed.
186 http://rt.cpan.org/Ticket/Display.html?id=28825
187
9b1ec2b8
TC
188 - moved the imtoc.perl code into Imager::Preprocess
189
190 - paste() and rubthrough() now adapt the source image data to the
191 destination, so you can now safely paste/rubthrough from greyscale
192 images to color images or back, or from alpha channel images to
193 noalpha channels or back.
194 https://rt.cpan.org/Ticket/Display.html?id=30908
195
196 - rubthrough() now falls back to pasting when the source doesn't have
197 an alpha channel. This effectively treats the source as having a
198 max alpha channel, the right thing to do.
199 http://rt.cpan.org/Ticket/Display.html?id=29944
200
201 - re-worked most of the area filling code to use a common set of
202 functions when filling.
203 Corrected normal combine mode.
204 Rewrote most of the combine modes to match the way the SVG draft
205 defines them with respect to a translucent source and destination.
206 Added tests for translucent source and destination.
207 Added tests to check 8-bit/sample and double/sample combines work
208 similarly.
209 https://rt.cpan.org/Ticket/Display.html?id=29879

07d9c639
TC
211 - writing a 2 or 4 channel image to a JPEG file will now write that
212 image as if composited against a background, black by default,
213 overridable with the i_background tag/parameter.

33b0ffa6
TC
226Bug fixes:
227
228 - Imager::Matrix2d->translate() now only requires one of the x or y
229 parameters.
230 http://rt.cpan.org/Ticket/Display.html?id=29937
231
2757bad0
TC
232 - mixing qtype scaling now sets all channels of a pixel to zero if
233 the pixel has zero coverage (zero alpha). This should produce more
234 compressible output files.
235 http://rt.cpan.org/Ticket/Display.html?id=32324
236
3da08517
TC
237 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
238 Noticed when I saw:
239 https://bugzilla.redhat.com/show_bug.cgi?id=166254
240 I'm not changing the #! lines of the sample code, since it's sample
241 code, not intended for installation.
242 http://rt.cpan.org/Ticket/Display.html?id=33408
243
242d7497
TC
244 - some TGA images weren't being detected correctly as TGA images
245 https://rt.cpan.org/Ticket/Display.html?id=32925
246
247 - handling of the left-over bit for 16-bit/pixel TGA images has been
248 changed to match the behaviour of the GIMP. Previously the bit
249 being set was treated as an opaque pixel, but one user reported a
250 problem with loading such an image. I haven't been able to find any
251 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
252 I'll match it's behaviour. See issue 114913 in the GIMP's
253 bugzilla.

259 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
260 to /path under your home directory.

262
50ff958e
TC
263 - the old dynaload code used Mach API functions to load dynamic
264 libraries on Mac OS X. These APIs have been deprecated in OS X
265 10.5 and were causing some build problems.
266 So henceforth Imager uses the dlopen() family of functions, and you
267 will need version 10.3 or later of OS X.
268
3309187a
TC
269 - added the det() function to the transform2() engine.

295 - major TIFF support re-work
296 http://rt.cpan.org/Ticket/Display.html?id=20329
297
298 - added a C level image interface for accessing samples from 1-32
299 bits, exposed this at the perl level in getsamples()
300
301 - the conv filter now works at floating point precision for high bit
302 images
303
304 - added is_bilevel method to test whether an image should be written as
305 a bilevel image if the image format supports it.
306
307 - added -log-stderr as an Imager import list option
308
309 - added some important types to Imager::APIRef

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

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

571Imager 0.55 - 16 Dec 2006
572===========
573
574This is primarily a bug fix release.
575
576Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
577
578There is one new feature:
579
580 - the Win32 font driver now supports UTF8 (RT 22166)
581 http://www.cpanforum.com/threads/3276
582 http://rt.cpan.org/Ticket/Display.html?id=22166
583
584Several bugs were fixed:
585
586 - the string() method would not output the string "0"
587 http://rt.cpan.org/Public/Bug/Display.html?id=21770
588
589 - fills.c was failing to compile on Solaris 10 (compiler unknown)
590 http://rt.cpan.org/Public/Bug/Display.html?id=21944
591
592 - the gif_disposal and gif_user_input tags weren't being read from
593 the file correctly
594 http://rt.cpan.org/Public/Bug/Display.html?id=22192
595
596 - gif.c was failing to build under MSVC
597 http://rt.cpan.org/Ticket/Display.html?id=23922
598
599 - in some cases strings passed to the string() method were treated as
600 terminated by NUL (chr 0)
601 http://rt.cpan.org/Public/Bug/Display.html?id=21770
602
603 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
604 that's the default build name for zlib on Win32.
605 http://rt.cpan.org/Ticket/Display.html?id=23064
606
607 - search $Config{incpath} for headers too, which we should have been
608 doing all along.
609
610Win32 font driver fixes:
611
612 - the global descent value from bounding box was the wrong sign
613 http://www.cpanforum.com/threads/3276
614
615 - if the first or last glyph overflowed the left or right side of the
616 advance width they would be clipped
617
618
619Imager 0.54 - 14 Sep 2006
620===========
621
622This is primarily a feature release:
623
624 - a new qtype value 'mixing' has been added to the scale()
625 method. This is faster than 'normal', slower than 'preview'. This
626 is based on the method used by pnmscale, and seems to produce less
627 blurry results than normal.
628 http://rt.cpan.org/Public/Bug/Display.html?id=20677
629
630 - the rubthrough() method can now render onto images with an alpha
631 channel.
632 http://rt.cpan.org/Ticket/Display.html?id=20678
633
634 - the read_multi() method now falls back to calling doing a single
635 image read via the read() method and write_multi() will now fall
636 back to calling write() if a single image is supplied. This means
637 you can simply call the read_multi() or write_multi() functions
638 without having to check if the type is formatted by that method.
639 http://rt.cpan.org/Ticket/Display.html?id=19457
640 http://rt.cpan.org/Ticket/Display.html?id=19458
641
642 - the GIF loop extension can now be written. If you don't have
643 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
644 should upgrade.
645 http://rt.cpan.org/Ticket/Display.html?id=21185
646
647 - getscanline() and setscanline() can now read/write palette index
648 based data from/to the image for paletted images, by setting type to
649 'index'.
650 http://rt.cpan.org/Ticket/Display.html?id=20338
651
652 - we no longer hassle you to disable GIF support
653 http://rt.cpan.org/Ticket/Display.html?id=20687
654
655 - minor documentation fixes
656
657
658Imager 0.53 - 26 Jul 2006
659===========
660
661This is a bugfix release.
662
663Some test code was left in a code path not covered by the test
664suite. A test was added to cover this code path and the test code was
665removed.
666http://rt.cpan.org/Public/Bug/Display.html?id=20705
667
668
669Imager 0.52 - 25 Jul 2006
670===========
671
672This is primarily a feature release, but contains a fair few bug
673fixes, new features:
674
675 - ability to read and write MS Windows ICO and CUR files
676
677 - you can now add file format plugins to support new file formats
678
679 - add POD coverage tests
680
681 - setcolors() and addcolors() now accept color names and so on
682 instead of requiring Imager::Color objects.
683 http://rt.cpan.org/Ticket/Display.html?id=20056
684
685 - flood_fill() can now fill to a specified border color instead of
686 just to the area the same color as the seed.
687 http://rt.cpan.org/Ticket/Display.html?id=19618
688
689
690Bug fixes:
691
692 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
693 calculating the advance width.
694 http://rt.cpan.org/Public/Bug/Display.html?id=20554
695
696 - bounding_box for the T1 driver wasn't including leading and
697 trailing spaces in the bounding box as the other drivers did, it also
698 produced strange results for empty strings or strings containing only
699 spaces
700
701 - when reading CMYK jpeg images they were being transferred to the
702 image object as is, producing a four channel image. It only looked ok
703 due to an old still unfixed Photoshop bug. We now convert from the
704 inverted CMYK that photoshop (and Corel for example) produce into RGB.
705 http://rt.cpan.org/Ticket/Display.html?id=20416
706
707 - reading a CYMK TIFF would result in a 4 channel image, reading any
708 image with more than 4 channels (eg. RGB with 2 alpha channels) would
709 result in an error.
710 http://rt.cpan.org/Ticket/Display.html?id=20415
711
712 - added /usr/local/include to the default include search path, since
713 we were already searching /usr/local/lib for libraries.
714
715And various minor fixes and documentation updates.
716
717

738 or 4 channel image to jpeg or a 2 channel image to tga where the
739 output is an in-memeory buffer.
740 http://rt.cpan.org/Public/Bug/Display.html?id=18397
741
742 - fixes an incorrect pointer parameter in the PNG code
