8 - add hsv() method to Imager::Color
9 Thanks to Leolo (Philip Gwyn)
10 https://rt.cpan.org/Ticket/Display.html?id=65385
12 - split libt1 Type 1 font support into a sub-module
13 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)

16 work around limitations in PAR.
17 https://rt.cpan.org/Ticket/Display.html?id=65665
21 - paletted writes to a masked image are now masked correctly.
22 Revealed by new coverage tests.

25 https://rt.cpan.org/Ticket/Display.html?id=56513
27 - add the matrix() method to Imager::Matrix2d to allow creation of a
28 matrix with specified co-efficients. You can now multiple an
29 Imager::Matrix2d object by a 9 element array ref or a number.
30 https://rt.cpan.org/Ticket/Display.html?id=29938
32 - really fix loading TTF fonts with FT2 when FT1 isn't available.
33 Thanks to Leolo (Philip Gwyn)
34 https://rt.cpan.org/Ticket/Display.html?id=65386
35 https://rt.cpan.org/Ticket/Display.html?id=62855
37 - make sure each test script that needs testout/ creates it.
38 https://rt.cpan.org/Ticket/Display.html?id=65088
40 - handle a slightly different warning from libtiff 4.x
41 https://rt.cpan.org/Ticket/Display.html?id=65268
43 - the sat transform2() op returned an incorrect saturation.
44 https://rt.cpan.org/Ticket/Display.html?id=65391
46 Imager 0.80 - 17 Jan 2011
49 - added coverage tests for Imager::Fountain and Imager::Color::Float
51 - Imager is now maintained in git
52 http://git.imager.perl.org/imager.git
53 git://git.imager.perl.org/imager.git
57 - images with an translucent alpha channel were not scaled correctly
58 by the default (qtype=normal) scaling method.
59 https://rt.cpan.org/Public/Bug/Display.html?id=63922
61 - Imager::Color::Float now translates "#FFFFFF" to white instead of
64 - make the default color map build algorithm "mediancut". This
65 changes the default color map builder for writing GIFs back to what
66 it was in 0.77, reverting a performance regression.
67 https://rt.cpan.org/Ticket/Display.html?id=64785
69 - handle failure to create a masked image correctly
71 Imager 0.79 - 10 Dec 2010
74 - add Imager::Test to the POD coverage tests and document the missing
77 - the convert() method now optimizes the case where all output
78 channels are either 0, sourced from a single input channel or 1.
79 This significantly speeds up presets like "addalpha", "green".
80 https://rt.cpan.org/Ticket/Display.html?id=51254
82 - add wiggle.pl sample, as suggested by Dan Oppenheim.
84 - add the combine() method to combine channels from multiple source
85 images into a new image
86 https://rt.cpan.org/Ticket/Display.html?id=11872
90 - treat the co-efficients for convert() as doubles instead of floats.
92 - If a higher (earlier) priority font handler failed to load, that
93 would crash preventing loading of later font handlers.
94 https://rt.cpan.org/Ticket/Display.html?id=62855
96 - parse defines from the options returned by pkg-config --cflags
97 https://rt.cpan.org/Ticket/Display.html?id=63223
99 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
100 included in the tarball. They are now included.
102 Imager 0.78 - 4 Oct 2010
107 - don't access deprecated members of the png_structp.
108 https://rt.cpan.org/Ticket/Display.html?id=60242
110 - document that using color objects is faster than supplying colors
112 https://rt.cpan.org/Ticket/Display.html?id=61047
114 - Imager::Probe now accepts array references for incpath and libpath.
115 https://rt.cpan.org/Ticket/Display.html?id=60244
117 Imager 0.77_02 - 27 Sep 2010
120 - moved Win32, FreeType 2 font support into sub-modules.
121 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
122 Uses Imager::Probe now.
123 https://rt.cpan.org/Public/Bug/Display.html?id=61328
125 - tested successfully with jpeg-8b
126 https://rt.cpan.org/Ticket/Display.html?id=60221
130 - from _01: look for missing file support test files in the right
133 - flood_fill() wouldn't fill the right side of a single scan-line
135 Thanks to Nicolas Roggli for reporting this.
137 - flood_fill wouldn't fill to the left edge of the image if the
138 starting line didn't reach the left edge.
139 Thanks to Nicolas Roggli for reporting this.
141 Imager 0.77_01 - 13 Sep 2010
144 - add each library-directory/pkgconfig/ to the pkg-config search path
146 Thanks to Justin Davis.
147 https://rt.cpan.org/Ticket/Display.html?id=60491
149 - moved GIF, TIFF, JPEG file handling code into sub-modules in
150 preparation for separate distribution.
151 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
153 - optimize filled box drawing (color, not fill)
157 - Imager::Probe was calling ExtUtils::Liblist to initialize
158 LD_RUN_PATH supplying an undefined value rather than the found
159 directory. Thanks to Justin Davis.
160 https://rt.cpan.org/Ticket/Display.html?id=60491
162 - only prepend ./ to font filenames when passing them to T1Lib and
163 then only when it would use its search mechanisms.
164 https://rt.cpan.org/Ticket/Display.html?id=60509
166 - fix the cache check for the X rgb.txt loader. This is typically
167 used for color translation on Unix-like systems, and the fix
168 improves performance of supplying colors by name by about 80 times.
169 Test code that managed 3400 10x10 pixel boxes/second sped up to
172 - clarify that Imager doesn't write EXIF metadata to images.
173 https://rt.cpan.org/Ticket/Display.html?id=60637
175 - Imager::Probe can now search subdirectories under its include path.
176 Used by the PNG Makefile.PL to find headers and libraries when they
177 aren't in the base directory, as in cygwin.
178 https://rt.cpan.org/Ticket/Display.html?id=60635
180 Imager 0.77 - 11 Aug 2010
183 I don't want Imager::File::PNG indexed as part of Imager, but forgot
184 to update the META.yml before updating the version.
186 - don't index Imager::File::PNG as part of Imager
188 - add resources to META.yml
190 Imager 0.76 - not released
195 - the align_string() method would ignore a string of "0" due to a
197 Thanks to Maurice Height for reporting this.
198 https://rt.cpan.org/Ticket/Display.html?id=60199
200 Imager 0.75_03 - 09 Aug 2010
205 - read_types() and write_types() would include png when it wasn't
206 available due to a problem with the %formats tie
208 - handle dependent libraries correctly (eg -lpng requiring -lz) in
209 the code run phase of library probing.
211 Imager 0.75_02 - 07 Aug 2010
216 - add file missing from MANIFEST, which was causing TIFF failures.
218 Imager 0.75_01 - 06 Aug 2010
221 Test release for the new PNG probe.
223 - added the ability to read multiple-image PNM files.
224 Note that unlike the pbm/pgm/ppm specification this accepts mixed
225 format files and allows white space padding between files.
226 Thanks to Philip Gwyn (Leolo) for this patch.
228 - moved the PNG file handling code into a sub-module in preparation
229 for separate distribution.
230 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
231 Also helps avoid complications from -I/-L compile/link options from
236 - Imager->new(data => $data) didn't try to process image file data in
238 https://rt.cpan.org/Ticket/Display.html?id=58761
240 - t/t50basicoo.t no longer depends on the other tests to generate its
242 https://rt.cpan.org/Ticket/Display.html?id=9798
243 Also, it wasn't testing pnm (pnm vs ppm mix-up)
245 - update the documentation of hardinvert to match the change in 0.62.
246 https://rt.cpan.org/Ticket/Display.html?id=59785
248 - added hardinvertall filter which also inverts the alpha channel
251 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
252 the probe can find the library for the test run.
253 https://rt.cpan.org/Ticket/Display.html?id=57518
255 Imager 0.75 - 20 Jun 2010
258 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
263 - an opacity fill based on a fountain fill would segfault when
264 filling an 8-bit/sample image.
266 - merge thickline branch polygon fix
267 https://rt.cpan.org/Ticket/Display.html?id=43518
269 Imager 0.74 - 7 May 2010
274 - read_multi() didn't handle a missing file format library correctly,
275 aborting on failing to call i_readgif_multi_wiol() or
276 i_readtiff_multi_wiol().
278 - fix spelling errors patched by Debian
279 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
281 - add an (unshipped) author test to spellcheck Imager's POD.
283 - update the TIFF file format documentation
284 https://rt.cpan.org/Ticket/Display.html?id=56510
286 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
288 Imager 0.73 - 15 Mar 2010
291 - implement outline circles, both anti-aliased and not
292 https://rt.cpan.org/Ticket/Display.html?id=19755
294 - a combine => "none" fill to a 1 or 3 channel image would produce
295 the incorrect colour.
297 Imager 0.72 - 09 Dec 2009
300 Bump version for release, since 0.71_03 is stable with CPAN testers.
302 Imager 0.71_03 - 5 Dec 2009
305 - further adjust the threads test so it only performs the tests on
306 perls where it's expected to work, and only if the threads module
309 Imager 0.71_02 - 1 Dec 2009
312 - adjust the way we load the threads module for the threads test so
313 it works with non-threaded perls
315 Imager 0.71_01 - 30 Nov 2009
320 - use scanline oriented operations to flip images instead of pixel
322 https://rt.cpan.org/Ticket/Display.html?id=39278
324 - use double/sample operations to flip large sample images instead of
325 8-bit sample operations.
326 https://rt.cpan.org/Ticket/Display.html?id=39280
329 https://rt.cpan.org/Ticket/Display.html?id=51874
331 - prevent double-frees when someone creates Imager objects and then
332 creates a thread. Note: this just handles some simple cases,
333 Imager doesn't support perl threads, and isn't likely to.
334 https://rt.cpan.org/Ticket/Display.html?id=52268
336 Imager 0.71 - 16 Nov 2009
339 - add the opacity fill type - an adaptor that modifies the opacity of
344 - the conv filter now enforces that the sum of the coefficients is
345 non-zero. Also, rather than skipping pixels off the edge off the
346 edge of the image, the closest edge pixel is used. Previously
347 dividing by the zero sum of coefficients could cause invalid
348 results or runtime exceptions.
349 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
352 Imager 0.70 - 21 Sep 2009
357 - release image row and comments memory on all error returns in gif
360 - handle zero length extensions, previously this would cause a null
362 Thanks to Krzysztof Wojtaś for the test data and fix for this.
364 - an integer division meant that preview scaling to below 1 pixel
365 wide or high (which isn't too useful anyway) was calculating using
366 NaNs on most platforms, and causing an exception on others.
367 Thanks to David Cantrell for producing a backtrace of the crash on
368 his Alpha-NetBSD CPAN test box which made it possible to track this
371 Imager 0.69 - 08 Sep 2009
376 - broken test fix - was attempting to call a function skip_all, when
377 that should be a parameter to plan().
379 - briefly document apidocs.perl, the tool used to build
380 Imager::APIRef and make some minor enhancements
382 - various minor documentation enhancements and fixes.
384 Imager 0.68 - 07 Sep 2009
387 - Imager->new(file => $filename) and other similar incantations will
389 https://rt.cpan.org/Ticket/Display.html?id=48261
393 - avoid using CHECK as a label in Imager::Test
394 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
396 - re-work most image file test files that require a library into
397 separate library present/not present files to remove stupidly long
400 - don't treat rubthrough() outside the bounds of the target image as
402 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
404 Imager 0.67_01 - 02 Sep 2009
409 - correct documentation of default of raw image interleave read
411 https://rt.cpan.org/Ticket/Display.html?id=42074
413 - add raw_ prefix to raw read parameters, though the original names
416 - fail the read if an invalid raw_interleave parameter is supplied
418 - warn if no interleave or raw_interleave parameter is supplied,
419 since the documented default was wrong, and incompatible with the
422 - for reading raw images, if raw_storechannels > raw_datachannels,
423 set the extra channels in the image to 0
425 - when probing for executables like freetype-config, search for .bat
426 and .cmd on MSWin32, as well as .exe.
427 https://rt.cpan.org/Ticket/Display.html?id=49275
429 - re-work the external libraries section of README:
430 - list Debian and Redhat package names for each library
434 - use the new EU::MM META_MERGE facility instead of generating
435 META.yml from scratch
436 https://rt.cpan.org/Ticket/Display.html?id=47888
438 - use Devel::CheckLib (bundled, modified) to check which release of
439 libtiff is installed and reject 3.9.0
440 http://bugzilla.maptools.org/show_bug.cgi?id=2088
441 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
443 Imager 0.67 - 12 Dec 2008
448 - fix a packaging error
450 Imager 0.66 - 12 Dec 2008
453 - 24-bit color .ICO/.CUR files can now be read.
457 - an optimization skipping 0 src alpha values could cause the
458 rubthrough() to read past the end of a buffer.
459 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
461 - corrected a reference leak where writing GIFs would leak memory.
462 This could also happen calling to_paletted().
463 Also documented the underlying long existing feature where the
464 colors parameter is filled with the generated color table and added
466 http://rt.cpan.org/Ticket/Display.html?id=41028
468 - write out the image size in bytes field of a BMP correctly.
469 http://rt.cpan.org/Ticket/Display.html?id=41406
471 - add limited tests for Imager::ExtUtils
473 - make Imager::ExtUtils->includes use an absolute path, since
474 a relative path could cause failures using Inline::C.
475 http://rt.cpan.org/Ticket/Display.html?id=37353
477 - re-arrange the POD for Imager::Font::BBox:
478 - mark total_width(), pos_width(), end_offset() obsolete, since
479 they're mostly for backwards compatibility
480 - group width methods and height methods
481 https://rt.cpan.org/Ticket/Display.html?id=39999
483 Imager 0.65 - 20 May 2008
488 - In some cases when an error occurs reading those parts of a JPEG
489 file after the image the scan-line buffer could be freed a second
490 time. In cases where the the error occured while reading the image
491 data it's possible that the buffer could have leaked.
492 Thanks to Gabriel Vasseur for reporting this and help in tracking
495 - the gif_screen_height tag was overriding the screen width and being
496 ignored for the screen height when present.
497 https://rt.cpan.org/Public/Bug/Display.html?id=35568
499 Imager 0.64 - 23 April 2008
502 This is a bug fix release. This includes a fix for a possible
507 - Possible security issue: The floating point sample path for image
508 based fills had a buffer overflow. This would overwrite the end of
509 a malloc()ed buffer with double precision floats.
510 http://rt.cpan.org/Ticket/Display.html?id=35324
513 - check that the result of fileno($fh) is defined rather than simply
514 true when read() or write() is supplied with an fh parameter.
515 http://rt.cpan.org/Ticket/Display.html?id=35139
517 - i_scale_axis() wasn't checking the result of i_img_new_ch()
518 resulting in a SIGSEGV when attempting to scale an image to a size
519 too large to fit in memory. This is a NULL pointer access issue,
520 not a buffer overflow.
521 Added a check for the failure.
522 scale_calculate() (and hence scale()) will now fail if any of the
523 scale size parameters are a reference.
524 http://rt.cpan.org/Ticket/Display.html?id=35172
526 - Regression: filling a greyscale image with a hatch used the wrong
527 color channels from the supplied fg/bg colors.
528 https://rt.cpan.org/Ticket/Display.html?id=35278
530 - fixed a related problem for image fills.
532 Imager 0.63 - 7 April 2008
535 This release primarily contains changes to improve ease of use -
536 rather than you having to convert images to the appropriate number of
537 channels, Imager handles it internally. How to handle drawing colors
538 and the default combine mode is a thornier problem left for some other
541 - the font libraries are now only initialized when needed.
542 http://rt.cpan.org/Ticket/Display.html?id=28825
544 - moved the imtoc.perl code into Imager::Preprocess
546 - paste() and rubthrough() now adapt the source image data to the
547 destination, so you can now safely paste/rubthrough from greyscale
548 images to color images or back, or from alpha channel images to
549 noalpha channels or back.
550 https://rt.cpan.org/Ticket/Display.html?id=30908
552 - rubthrough() now falls back to pasting when the source doesn't have
553 an alpha channel. This effectively treats the source as having a
554 max alpha channel, the right thing to do.
555 http://rt.cpan.org/Ticket/Display.html?id=29944
557 - re-worked most of the area filling code to use a common set of
558 functions when filling.
559 Corrected normal combine mode.
560 Rewrote most of the combine modes to match the way the SVG draft
561 defines them with respect to a translucent source and destination.
562 Added tests for translucent source and destination.
563 Added tests to check 8-bit/sample and double/sample combines work
565 https://rt.cpan.org/Ticket/Display.html?id=29879
567 - writing a 2 or 4 channel image to a JPEG file will now write that
568 image as if composited against a background, black by default,
569 overridable with the i_background tag/parameter.
570 https://rt.cpan.org/Ticket/Display.html?id=29876
572 - writing a 2 or 4 channel image to a PGM/PPM file will now write
573 that image as if composited against a background, black by default,
574 overridable with the i_background tag/parameter.
575 http://rt.cpan.org/Ticket/Display.html?id=30074
577 - writing a 2 or 4 channel image to a BMP file will now write that
578 image as if composited against a background, black by default,
579 overridable with the i_background tag/parameter.
580 http://rt.cpan.org/Ticket/Display.html?id=30075
584 - Imager::Matrix2d->translate() now only requires one of the x or y
586 http://rt.cpan.org/Ticket/Display.html?id=29937
588 - mixing qtype scaling now sets all channels of a pixel to zero if
589 the pixel has zero coverage (zero alpha). This should produce more
590 compressible output files.
591 http://rt.cpan.org/Ticket/Display.html?id=32324
593 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
595 https://bugzilla.redhat.com/show_bug.cgi?id=166254
596 I'm not changing the #! lines of the sample code, since it's sample
597 code, not intended for installation.
598 http://rt.cpan.org/Ticket/Display.html?id=33408
600 - some TGA images weren't being detected correctly as TGA images
601 https://rt.cpan.org/Ticket/Display.html?id=32925
603 - handling of the left-over bit for 16-bit/pixel TGA images has been
604 changed to match the behaviour of the GIMP. Previously the bit
605 being set was treated as an opaque pixel, but one user reported a
606 problem with loading such an image. I haven't been able to find any
607 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
608 I'll match it's behaviour. See issue 114913 in the GIMP's
610 http://rt.cpan.org/Ticket/Display.html?id=32926
612 Imager 0.62 - 10 December 2007
615 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
616 to /path under your home directory.
617 http://rt.cpan.org/Ticket/Display.html?id=29484
619 - the old dynaload code used Mach API functions to load dynamic
620 libraries on Mac OS X. These APIs have been deprecated in OS X
621 10.5 and were causing some build problems.
622 So henceforth Imager uses the dlopen() family of functions, and you
623 will need version 10.3 or later of OS X.
625 - added the det() function to the transform2() engine.
626 added the sample quad_to_square.pl
627 Courtesy Richard Fairhurst.
628 http://rt.cpan.org/Ticket/Display.html?id=31244
632 - samples/gifscale.pl sourced the base value for gif_top from
634 Thanks to Eleneldil G. Arilou for pointing this out.
636 - t/t82inline.t no longer loads B at runtime, to work around a bug
637 in some 5.005_0[45] installations.
638 http://rt.cpan.org/Ticket/Display.html?id=30508
640 - work around Module::Depends::Intrusive bug #21229
641 http://rt.cpan.org/Ticket/Display.html?id=30520
643 - the hardinvert filter no-longer inverts the alpha channel.
644 http://rt.cpan.org/Ticket/Display.html?id=30002
646 - the hardinvert filter now supports large samples
648 Imager 0.61_02 - 28 November 2007
651 - major TIFF support re-work
652 http://rt.cpan.org/Ticket/Display.html?id=20329
654 - added a C level image interface for accessing samples from 1-32
655 bits, exposed this at the perl level in getsamples()
657 - the conv filter now works at floating point precision for high bit
660 - added is_bilevel method to test whether an image should be written as
661 a bilevel image if the image format supports it.
663 - added -log-stderr as an Imager import list option
665 - added some important types to Imager::APIRef
667 - added test_image_double() to Imager::Test
671 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
674 - the scale() method with qtype mixing now handles images with an
675 alpha channel correctly.
677 - fixed a broken link from the "animated GIF" entry in the concept index.
678 Thanks to Slaven Rezic.

681 - on some perl's the infix expression parser test would fail due to
682 actions in the grammar returning false. Made sure all actions return
684 Thanks to Richard Fairhurst for spending a lot of time in tracking

688 Imager 0.61 - 5 November 2007
691 - added samples/gifscale.pl, which adjusts the screen size/position tags
692 when scaling an animated gif
693 http://rt.cpan.org/Ticket/Display.html?id=27591
697 - correct handling of sz in matrix_transform() - this should allow
698 perspective type transformations to work now.
699 http://rt.cpan.org/Ticket/Display.html?id=29936
701 - prevent a cast to integer warning on x64 builds in datatypes.c
702 also fixed some other type warnings
703 https://rt.cpan.org/Ticket/Display.html?id=30204
705 - some sub-directory tests depended on files produced by the parent
707 http://rt.cpan.org/Ticket/Display.html?id=30203
709 - Imager::Font::Wrap doesn't correctly set savepos
710 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
711 http://rt.cpan.org/Ticket/Display.html?id=29771
713 - test 171 in t/t01introvert.t was failing on perls configured to
715 http://rt.cpan.org/Ticket/Display.html?id=29413
717 - the code for the transform2() uminus operator was missing a break.
718 Added tests for better code coverage of the ops.
719 http://rt.cpan.org/Ticket/Display.html?id=29296
721 - the SGI RLE compression code could overflow its compression buffer
722 http://rt.cpan.org/Ticket/Display.html?id=30334
724 - the 32-bit output function used by the SGI code only handled values
725 under 0x10000. This was most noticable when writing large RLE images.
726 http://rt.cpan.org/Ticket/Display.html?id=30335
728 - validate chan_count for chans == NULL for each of the i_gsamp()
730 http://rt.cpan.org/Ticket/Display.html?id=28985
732 - attempt to work around the test failure at
733 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
734 http://rt.cpan.org/Ticket/Display.html?id=29562
736 - improve the error messages produced when attempting to read or write
737 an unknown image file format.
738 http://rt.cpan.org/Ticket/Display.html?id=30103
740 - improve the transform2() documentation
741 http://rt.cpan.org/Ticket/Display.html?id=29267
743 - correctly generate the author key in META.yml
744 http://rt.cpan.org/Ticket/Display.html?id=30377
746 - correctly blend a rotated (or matrix_transformed()) image when
747 performing interpolation in the presence of an alpha channel.
748 Also corrected the centring of the rotated image on the output
751 Imager 0.60 - 30 August 2007
754 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
755 now has full SGI RGB image format, including RLE and 16-bit/sample
757 https://rt.cpan.org/Ticket/Display.html?id=8666
759 - logging functions are now available in the API
761 - applied Gabriel Vasseur's patch
762 added documentation, further tests, and support for greyscale images
763 Obviously problems are my fault :)
764 https://rt.cpan.org/Ticket/Display.html?id=28142
766 - the mask for ICO/CUR images is now applied as an alpha channel to
767 the returned image. For the old behaviour, supply ico_masked => 0
768 to read() or read_multi(). This should be less confusing when
769 using Imager as a general image processor.
770 https://rt.cpan.org/Ticket/Display.html?id=29001
774 - in some cases it's possible for giflib/libungif to return color
775 indexes outside the range of colors defined by the image's palette.
776 We now expand the palette to match the indexes used.
777 Thanks to Gabriel Vasseur for reporting this.
779 - fixed various memory leaks that could occur when failing to read png,
780 jpeg, bmp or tga files.
782 - to avoid confusion, channels not present in the image are returned as
783 zero by getscanline(). This has no effect on the C level i_glin()
784 and i_glinf() API functions which continue to not set the unused
787 - the convert() method now returns an image of the same sample size as
789 https://rt.cpan.org/Ticket/Display.html?id=28492
791 - remove repeated text in Imager::Files
792 http://rt.cpan.org/Ticket/Display.html?id=27589
794 - be even more explicit that scale() and friends don't modify the source
795 image, but return a new image.
796 http://rt.cpan.org/Ticket/Display.html?id=28570
798 - improve the error message from errstr() when you try to load a font
799 for which the driver hasn't been built in Imager.
800 http://rt.cpan.org/Ticket/Display.html?id=27571
802 - transparency is now enabled by default when writing GIF images
803 http://rt.cpan.org/Ticket/Display.html?id=27615
805 - Imager would not load on Windows 98
806 http://rt.cpan.org/Ticket/Display.html?id=27653
808 Imager 0.59 - 14 June 2007
813 - fixes a regression introduced by the fixes for RT 11972
814 http://rt.cpan.org/Ticket/Display.html?id=27546
816 - cropping outside the image would return an Imager object with
817 no low-level image object, instead of returning false.
818 Fixed by: Philip Gwyn (Leolo)
819 http://rt.cpan.org/Ticket/Display.html?id=27509
821 Imager 0.58 - 16 May 2007
824 No significant changes from 0.57_01.
826 Imager 0.57_01 - 11 May 2007
829 - added to_rgb16 to produce a 16-bit/sample version of an image
831 - improve freetype 1.x text output efficiency
835 - search another place for rgb.txt, and check all the places
836 Imager::Color checks when deciding whether to skip testing it
837 http://rt.cpan.org/Ticket/Display.html?id=26064
839 - use a convolution kernel size based on the stddev rather than a
840 fixed size when performing a gaussian blur
841 http://rt.cpan.org/Ticket/Display.html?id=25645
843 - document the difference() method's mindist parameter, and debug it.
845 - put the Imager release number in the Inline::C generated code to
846 regenerate Inline code when a new release of Imager is installed.
847 http://rt.cpan.org/Ticket/Display.html?id=26278
849 - fix rendering on alpha channel images for the FreeType 1.x driver.
850 http://rt.cpan.org/Ticket/Display.html?id=11972
852 - fix rendering on alpha channel images for the T1lib driver.
853 http://rt.cpan.org/Ticket/Display.html?id=11972
855 - reworked library probing, we can now set more than one probe
856 function for a library. Disabled the default (non-freetype-config)
857 library probe and added an extra probe function that searches for
858 both ft2build.h and whatever it includes, and adds -I as needed.
859 Hopefully this will fix build problems like
860 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
861 http://rt.cpan.org/Ticket/Display.html?id=26086
863 Imager 0.57 - 30 Apr 2007
866 This is a maintenence release fixing a security issue in Imager.
868 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
869 overflow in malloced memory. There will be further discussion of
870 this issue in the ticket below.
871 http://rt.cpan.org/Ticket/Display.html?id=26811
872 CVE-2007-2459 CVE-2007-2413
873 The descriptions at cve.mitre.org varied in quality, please see the
874 ticket at rt.cpan.org for a more accurate description of the issue.
876 Imager 0.56 - 1 Apr 2007
879 - added support for reading 16-bit/sample PGM/PPM images
881 - added support for writing 16-bit/sample PGM/PPM images
883 - improved performance of reading PBM/PGM/PPM images
885 - added support for writing PBM images if the image is paletted and
886 contains only black and white
888 - added a new make_colors value - "mono"
890 - switched from the svn log Changes to a manual Changes to reduce
893 - new sample code - samples/flasher.pl
897 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
898 was returning an image object with an extra reference, this
899 resulted in a memory leak.
900 http://rt.cpan.org/Ticket/Display.html?id=24992
902 - fix rendering on alpha channel images for the FreeType 2.x driver
903 http://rt.cpan.org/Ticket/Display.html?id=11972
905 - reading bmp files now consitently handles short reads. You can now
906 supply a parameter to treat a short read as successful and set
908 http://rt.cpan.org/Ticket/Display.html?id=8426
910 - previously, reading ASCII PBM files required spaces between samples,
911 even though the format doesn't require that
913 - improved documentation of the unsharpmask filter (I hope)
914 http://rt.cpan.org/Ticket/Display.html?id=25531
916 - force flushing of the output from i_tt_dump_names() and test output
917 in t/t35ttfont.t to prevent output from being mixed up.
918 https://rt.cpan.org/Ticket/Display.html?id=24859
920 - rewrite a conditional expression as an if() to hopefully work around
921 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
922 https://rt.cpan.org/Ticket/Display.html?id=25561
924 - avoid Data::Dumper in regops.perl to support older releases of perl
925 https://rt.cpan.org/Ticket/Display.html?id=24391
927 Imager 0.55 - 16 Dec 2006
930 This is primarily a bug fix release.
932 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
934 There is one new feature:
936 - the Win32 font driver now supports UTF8 (RT 22166)
937 http://www.cpanforum.com/threads/3276
938 http://rt.cpan.org/Ticket/Display.html?id=22166
940 Several bugs were fixed:
942 - the string() method would not output the string "0"
943 http://rt.cpan.org/Public/Bug/Display.html?id=21770
945 - fills.c was failing to compile on Solaris 10 (compiler unknown)
946 http://rt.cpan.org/Public/Bug/Display.html?id=21944
948 - the gif_disposal and gif_user_input tags weren't being read from
950 http://rt.cpan.org/Public/Bug/Display.html?id=22192
952 - gif.c was failing to build under MSVC
953 http://rt.cpan.org/Ticket/Display.html?id=23922
955 - in some cases strings passed to the string() method were treated as
956 terminated by NUL (chr 0)
957 http://rt.cpan.org/Public/Bug/Display.html?id=21770
959 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
960 that's the default build name for zlib on Win32.
961 http://rt.cpan.org/Ticket/Display.html?id=23064
963 - search $Config{incpath} for headers too, which we should have been
966 Win32 font driver fixes:
968 - the global descent value from bounding box was the wrong sign
969 http://www.cpanforum.com/threads/3276
971 - if the first or last glyph overflowed the left or right side of the
972 advance width they would be clipped
975 Imager 0.54 - 14 Sep 2006
978 This is primarily a feature release:
980 - a new qtype value 'mixing' has been added to the scale()
981 method. This is faster than 'normal', slower than 'preview'. This
982 is based on the method used by pnmscale, and seems to produce less
983 blurry results than normal.
984 http://rt.cpan.org/Public/Bug/Display.html?id=20677
986 - the rubthrough() method can now render onto images with an alpha
988 http://rt.cpan.org/Ticket/Display.html?id=20678
990 - the read_multi() method now falls back to calling doing a single
991 image read via the read() method and write_multi() will now fall
992 back to calling write() if a single image is supplied. This means
993 you can simply call the read_multi() or write_multi() functions
994 without having to check if the type is formatted by that method.
995 http://rt.cpan.org/Ticket/Display.html?id=19457
996 http://rt.cpan.org/Ticket/Display.html?id=19458
998 - the GIF loop extension can now be written. If you don't have
999 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1001 http://rt.cpan.org/Ticket/Display.html?id=21185
1003 - getscanline() and setscanline() can now read/write palette index
1004 based data from/to the image for paletted images, by setting type to
1006 http://rt.cpan.org/Ticket/Display.html?id=20338
1008 - we no longer hassle you to disable GIF support
1009 http://rt.cpan.org/Ticket/Display.html?id=20687
1011 - minor documentation fixes
1014 Imager 0.53 - 26 Jul 2006
1017 This is a bugfix release.
1019 Some test code was left in a code path not covered by the test
1020 suite. A test was added to cover this code path and the test code was
1022 http://rt.cpan.org/Public/Bug/Display.html?id=20705
1025 Imager 0.52 - 25 Jul 2006
1028 This is primarily a feature release, but contains a fair few bug
1029 fixes, new features:
1031 - ability to read and write MS Windows ICO and CUR files
1033 - you can now add file format plugins to support new file formats
1035 - add POD coverage tests
1037 - setcolors() and addcolors() now accept color names and so on
1038 instead of requiring Imager::Color objects.
1039 http://rt.cpan.org/Ticket/Display.html?id=20056
1041 - flood_fill() can now fill to a specified border color instead of
1042 just to the area the same color as the seed.
1043 http://rt.cpan.org/Ticket/Display.html?id=19618
1048 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1049 calculating the advance width.
1050 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1052 - bounding_box for the T1 driver wasn't including leading and
1053 trailing spaces in the bounding box as the other drivers did, it also
1054 produced strange results for empty strings or strings containing only
1057 - when reading CMYK jpeg images they were being transferred to the
1058 image object as is, producing a four channel image. It only looked ok
1059 due to an old still unfixed Photoshop bug. We now convert from the
1060 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1061 http://rt.cpan.org/Ticket/Display.html?id=20416
1063 - reading a CYMK TIFF would result in a 4 channel image, reading any
1064 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1066 http://rt.cpan.org/Ticket/Display.html?id=20415
1068 - added /usr/local/include to the default include search path, since
1069 we were already searching /usr/local/lib for libraries.
1071 And various minor fixes and documentation updates.
1074 Imager 0.51 - 23 Apr 2006
1077 - fix a validation bug when processing JPEG EXIF data that can cause
1079 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1081 - fix mis-processing of the src_maxx and src_maxy parameters of the
1083 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1085 - fix a problem in Imager's "smart" handling of the color parameter
1087 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1090 Imager 0.50 - 29 Mar 2006
1093 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1094 or 4 channel image to jpeg or a 2 channel image to tga where the
1095 output is an in-memeory buffer.
1096 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1098 - fixes an incorrect pointer parameter in the PNG code
1099 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1101 - skip Inline::C tests when building in a directory with spaces
1102 http://rt.cpan.org/Public/Bug/Display.html?id=18049
