3 Imager 0.84 (** update GIF, TIFF, W32, PNG, JPEG, FT2 versions!)
6 - Imager no longer inherits from Exporter (unless you're running an
9 - Imager can now write progressive JPEGs (it could always read them).
10 https://rt.cpan.org/Ticket/Display.html?id=68691
14 - re-work, document and test Imager's logging facility.
15 https://rt.cpan.org/Ticket/Display.html?id=65227
17 - fix META.yml testing and the generated META.yml
18 https://rt.cpan.org/Ticket/Display.html?id=65235
20 - test and add error reporting to to_*() family methods
22 - add to_rgb_double() method.
23 https://rt.cpan.org/Ticket/Display.html?id=65101
25 - Imager no longer exports anything by default
26 https://rt.cpan.org/Ticket/Display.html?id=65228
28 - convert colors to grayscale if the supplied (or generated) palette
29 contains only grays when performing error diffusion color
31 https://rt.cpan.org/Ticket/Display.html?id=68508
33 - writing a paletted image to GIF wouldn't always use the colors
34 supplied (or generated, eg. via make_colors => "mono"), which was
36 https://rt.cpan.org/Ticket/Display.html?id=67912
38 - replace (imager|tony)@imager.perl.org in the doc, since I don't
39 plan to continue receiving mail at that address.
40 https://rt.cpan.org/Ticket/Display.html?id=68591
42 Imager 0.83 - 21 May 2011
47 - diag() the error message on failure for some TIFF tests that are
48 failing on a Solaris smoker.
49 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
51 Imager 0.82_01 - 17 May 2011
54 Dev release, in case the compose tests are too sensitive.
58 - Imager::Font::T1 incorrectly checked for absolute filename under
59 Win32. Thanks to kmx for the report and fix.
60 https://rt.cpan.org/Ticket/Display.html?id=67963
62 - compose() with the target, source or mask position off the top or
63 left of the target image didn't clip the source image correctly.
64 https://rt.cpan.org/Ticket/Display.html?id=67220
66 - compose() now returns a useful error message on a non-positive
69 - compose.im now at 100% test coverage. (As opposed to, umm, much,
72 Imager 0.82 - 14 Mar 2011
77 - eliminate calls to i_has_format() from the test suite, since it's
78 no longer a useful way to check for file format support. Eliminate
79 i_has_format() from the functions exposed via XS.
80 https://rt.cpan.org/Ticket/Display.html?id=65863
82 - eliminate calls to note(), which isn't in the (very old) version of
83 Test::More we have as a pre-requisite. note() is modern enough
84 that I don't feel a need to require a Test::More upgrade for it.
85 https://rt.cpan.org/Ticket/Display.html?id=65864
87 - skip the threads tests on Test::More 2.00_*
88 https://rt.cpan.org/Ticket/Display.html?id=65812
90 - add an (unshipped) test to check Imager's internal POD links
91 https://rt.cpan.org/Ticket/Display.html?id=65749
93 - improve the library detection summary
94 https://rt.cpan.org/Ticket/Display.html?id=9675
96 - increase the version of Imager::Font::Type1 so that upgrades don't
97 downgrade the version in this file.
98 https://rt.cpan.org/Ticket/Display.html?id=66250
100 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
101 that option for the directories that would normally go in
102 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
103 https://rt.cpan.org/Ticket/Display.html?id=65955
105 Imager 0.81 - 14 Feb 2011
108 - added coverage tests for masked images (maskimg.c @100% test coverage)
110 - add hsv() method to Imager::Color
111 Thanks to Leolo (Philip Gwyn)
112 https://rt.cpan.org/Ticket/Display.html?id=65385
114 - split libt1 Type 1 font support into a sub-module
115 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
117 - add a preload() class method for use in forking servers, and to
118 work around limitations in PAR.
119 https://rt.cpan.org/Ticket/Display.html?id=65665
123 - paletted writes to a masked image are now masked correctly.
124 Revealed by new coverage tests.
126 - update the filter plugin documentation.
127 https://rt.cpan.org/Ticket/Display.html?id=56513
129 - add the matrix() method to Imager::Matrix2d to allow creation of a
130 matrix with specified co-efficients. You can now multiple an
131 Imager::Matrix2d object by a 9 element array ref or a number.
132 https://rt.cpan.org/Ticket/Display.html?id=29938
134 - really fix loading TTF fonts with FT2 when FT1 isn't available.
135 Thanks to Leolo (Philip Gwyn)
136 https://rt.cpan.org/Ticket/Display.html?id=65386
137 https://rt.cpan.org/Ticket/Display.html?id=62855
139 - make sure each test script that needs testout/ creates it.
140 https://rt.cpan.org/Ticket/Display.html?id=65088
142 - handle a slightly different warning from libtiff 4.x
143 https://rt.cpan.org/Ticket/Display.html?id=65268
145 - the sat transform2() op returned an incorrect saturation.
146 https://rt.cpan.org/Ticket/Display.html?id=65391
148 Imager 0.80 - 17 Jan 2011
151 - added coverage tests for Imager::Fountain and Imager::Color::Float
153 - Imager is now maintained in git
154 http://git.imager.perl.org/imager.git
155 git://git.imager.perl.org/imager.git
159 - images with an translucent alpha channel were not scaled correctly
160 by the default (qtype=normal) scaling method.
161 https://rt.cpan.org/Public/Bug/Display.html?id=63922
163 - Imager::Color::Float now translates "#FFFFFF" to white instead of
164 just a little darker.
166 - make the default color map build algorithm "mediancut". This
167 changes the default color map builder for writing GIFs back to what
168 it was in 0.77, reverting a performance regression.
169 https://rt.cpan.org/Ticket/Display.html?id=64785
171 - handle failure to create a masked image correctly
173 Imager 0.79 - 10 Dec 2010
176 - add Imager::Test to the POD coverage tests and document the missing
179 - the convert() method now optimizes the case where all output
180 channels are either 0, sourced from a single input channel or 1.
181 This significantly speeds up presets like "addalpha", "green".
182 https://rt.cpan.org/Ticket/Display.html?id=51254
184 - add wiggle.pl sample, as suggested by Dan Oppenheim.
186 - add the combine() method to combine channels from multiple source
187 images into a new image
188 https://rt.cpan.org/Ticket/Display.html?id=11872
192 - treat the co-efficients for convert() as doubles instead of floats.
194 - If a higher (earlier) priority font handler failed to load, that
195 would crash preventing loading of later font handlers.
196 https://rt.cpan.org/Ticket/Display.html?id=62855
198 - parse defines from the options returned by pkg-config --cflags
199 https://rt.cpan.org/Ticket/Display.html?id=63223
201 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
202 included in the tarball. They are now included.
204 Imager 0.78 - 4 Oct 2010
209 - don't access deprecated members of the png_structp.
210 https://rt.cpan.org/Ticket/Display.html?id=60242
212 - document that using color objects is faster than supplying colors
214 https://rt.cpan.org/Ticket/Display.html?id=61047
216 - Imager::Probe now accepts array references for incpath and libpath.
217 https://rt.cpan.org/Ticket/Display.html?id=60244
219 Imager 0.77_02 - 27 Sep 2010
222 - moved Win32, FreeType 2 font support into sub-modules.
223 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
224 Uses Imager::Probe now.
225 https://rt.cpan.org/Public/Bug/Display.html?id=61328
227 - tested successfully with jpeg-8b
228 https://rt.cpan.org/Ticket/Display.html?id=60221
232 - from _01: look for missing file support test files in the right
235 - flood_fill() wouldn't fill the right side of a single scan-line
237 Thanks to Nicolas Roggli for reporting this.
239 - flood_fill wouldn't fill to the left edge of the image if the
240 starting line didn't reach the left edge.
241 Thanks to Nicolas Roggli for reporting this.
243 Imager 0.77_01 - 13 Sep 2010
246 - add each library-directory/pkgconfig/ to the pkg-config search path
248 Thanks to Justin Davis.
249 https://rt.cpan.org/Ticket/Display.html?id=60491
251 - moved GIF, TIFF, JPEG file handling code into sub-modules in
252 preparation for separate distribution.
253 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
255 - optimize filled box drawing (color, not fill)
259 - Imager::Probe was calling ExtUtils::Liblist to initialize
260 LD_RUN_PATH supplying an undefined value rather than the found
261 directory. Thanks to Justin Davis.
262 https://rt.cpan.org/Ticket/Display.html?id=60491
264 - only prepend ./ to font filenames when passing them to T1Lib and
265 then only when it would use its search mechanisms.
266 https://rt.cpan.org/Ticket/Display.html?id=60509
268 - fix the cache check for the X rgb.txt loader. This is typically
269 used for color translation on Unix-like systems, and the fix
270 improves performance of supplying colors by name by about 80 times.
271 Test code that managed 3400 10x10 pixel boxes/second sped up to
274 - clarify that Imager doesn't write EXIF metadata to images.
275 https://rt.cpan.org/Ticket/Display.html?id=60637
277 - Imager::Probe can now search subdirectories under its include path.
278 Used by the PNG Makefile.PL to find headers and libraries when they
279 aren't in the base directory, as in cygwin.
280 https://rt.cpan.org/Ticket/Display.html?id=60635
282 Imager 0.77 - 11 Aug 2010
285 I don't want Imager::File::PNG indexed as part of Imager, but forgot
286 to update the META.yml before updating the version.
288 - don't index Imager::File::PNG as part of Imager
290 - add resources to META.yml
292 Imager 0.76 - not released
297 - the align_string() method would ignore a string of "0" due to a
299 Thanks to Maurice Height for reporting this.
300 https://rt.cpan.org/Ticket/Display.html?id=60199
302 Imager 0.75_03 - 09 Aug 2010
307 - read_types() and write_types() would include png when it wasn't
308 available due to a problem with the %formats tie
310 - handle dependent libraries correctly (eg -lpng requiring -lz) in
311 the code run phase of library probing.
313 Imager 0.75_02 - 07 Aug 2010
318 - add file missing from MANIFEST, which was causing TIFF failures.
320 Imager 0.75_01 - 06 Aug 2010
323 Test release for the new PNG probe.
325 - added the ability to read multiple-image PNM files.
326 Note that unlike the pbm/pgm/ppm specification this accepts mixed
327 format files and allows white space padding between files.
328 Thanks to Philip Gwyn (Leolo) for this patch.
330 - moved the PNG file handling code into a sub-module in preparation
331 for separate distribution.
332 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
333 Also helps avoid complications from -I/-L compile/link options from
338 - Imager->new(data => $data) didn't try to process image file data in
340 https://rt.cpan.org/Ticket/Display.html?id=58761
342 - t/t50basicoo.t no longer depends on the other tests to generate its
344 https://rt.cpan.org/Ticket/Display.html?id=9798
345 Also, it wasn't testing pnm (pnm vs ppm mix-up)
347 - update the documentation of hardinvert to match the change in 0.62.
348 https://rt.cpan.org/Ticket/Display.html?id=59785
350 - added hardinvertall filter which also inverts the alpha channel
353 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
354 the probe can find the library for the test run.
355 https://rt.cpan.org/Ticket/Display.html?id=57518
357 Imager 0.75 - 20 Jun 2010
360 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
365 - an opacity fill based on a fountain fill would segfault when
366 filling an 8-bit/sample image.
368 - merge thickline branch polygon fix
369 https://rt.cpan.org/Ticket/Display.html?id=43518
371 Imager 0.74 - 7 May 2010
376 - read_multi() didn't handle a missing file format library correctly,
377 aborting on failing to call i_readgif_multi_wiol() or
378 i_readtiff_multi_wiol().
380 - fix spelling errors patched by Debian
381 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
383 - add an (unshipped) author test to spellcheck Imager's POD.
385 - update the TIFF file format documentation
386 https://rt.cpan.org/Ticket/Display.html?id=56510
388 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
390 Imager 0.73 - 15 Mar 2010
393 - implement outline circles, both anti-aliased and not
394 https://rt.cpan.org/Ticket/Display.html?id=19755
396 - a combine => "none" fill to a 1 or 3 channel image would produce
397 the incorrect colour.
399 Imager 0.72 - 09 Dec 2009
402 Bump version for release, since 0.71_03 is stable with CPAN testers.
404 Imager 0.71_03 - 5 Dec 2009
407 - further adjust the threads test so it only performs the tests on
408 perls where it's expected to work, and only if the threads module
411 Imager 0.71_02 - 1 Dec 2009
414 - adjust the way we load the threads module for the threads test so
415 it works with non-threaded perls
417 Imager 0.71_01 - 30 Nov 2009
422 - use scanline oriented operations to flip images instead of pixel
424 https://rt.cpan.org/Ticket/Display.html?id=39278
426 - use double/sample operations to flip large sample images instead of
427 8-bit sample operations.
428 https://rt.cpan.org/Ticket/Display.html?id=39280
431 https://rt.cpan.org/Ticket/Display.html?id=51874
433 - prevent double-frees when someone creates Imager objects and then
434 creates a thread. Note: this just handles some simple cases,
435 Imager doesn't support perl threads, and isn't likely to.
436 https://rt.cpan.org/Ticket/Display.html?id=52268
438 Imager 0.71 - 16 Nov 2009
441 - add the opacity fill type - an adaptor that modifies the opacity of
446 - the conv filter now enforces that the sum of the coefficients is
447 non-zero. Also, rather than skipping pixels off the edge off the
448 edge of the image, the closest edge pixel is used. Previously
449 dividing by the zero sum of coefficients could cause invalid
450 results or runtime exceptions.
451 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
454 Imager 0.70 - 21 Sep 2009
459 - release image row and comments memory on all error returns in gif
462 - handle zero length extensions, previously this would cause a null
464 Thanks to Krzysztof Wojtaś for the test data and fix for this.
466 - an integer division meant that preview scaling to below 1 pixel
467 wide or high (which isn't too useful anyway) was calculating using
468 NaNs on most platforms, and causing an exception on others.
469 Thanks to David Cantrell for producing a backtrace of the crash on
470 his Alpha-NetBSD CPAN test box which made it possible to track this
473 Imager 0.69 - 08 Sep 2009
478 - broken test fix - was attempting to call a function skip_all, when
479 that should be a parameter to plan().
481 - briefly document apidocs.perl, the tool used to build
482 Imager::APIRef and make some minor enhancements
484 - various minor documentation enhancements and fixes.
486 Imager 0.68 - 07 Sep 2009
489 - Imager->new(file => $filename) and other similar incantations will
491 https://rt.cpan.org/Ticket/Display.html?id=48261
495 - avoid using CHECK as a label in Imager::Test
496 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
498 - re-work most image file test files that require a library into
499 separate library present/not present files to remove stupidly long
502 - don't treat rubthrough() outside the bounds of the target image as
504 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
506 Imager 0.67_01 - 02 Sep 2009
511 - correct documentation of default of raw image interleave read
513 https://rt.cpan.org/Ticket/Display.html?id=42074
515 - add raw_ prefix to raw read parameters, though the original names
518 - fail the read if an invalid raw_interleave parameter is supplied
520 - warn if no interleave or raw_interleave parameter is supplied,
521 since the documented default was wrong, and incompatible with the
524 - for reading raw images, if raw_storechannels > raw_datachannels,
525 set the extra channels in the image to 0
527 - when probing for executables like freetype-config, search for .bat
528 and .cmd on MSWin32, as well as .exe.
529 https://rt.cpan.org/Ticket/Display.html?id=49275
531 - re-work the external libraries section of README:
532 - list Debian and Redhat package names for each library
536 - use the new EU::MM META_MERGE facility instead of generating
537 META.yml from scratch
538 https://rt.cpan.org/Ticket/Display.html?id=47888
540 - use Devel::CheckLib (bundled, modified) to check which release of
541 libtiff is installed and reject 3.9.0
542 http://bugzilla.maptools.org/show_bug.cgi?id=2088
543 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
545 Imager 0.67 - 12 Dec 2008
550 - fix a packaging error
552 Imager 0.66 - 12 Dec 2008
555 - 24-bit color .ICO/.CUR files can now be read.
559 - an optimization skipping 0 src alpha values could cause the
560 rubthrough() to read past the end of a buffer.
561 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
563 - corrected a reference leak where writing GIFs would leak memory.
564 This could also happen calling to_paletted().
565 Also documented the underlying long existing feature where the
566 colors parameter is filled with the generated color table and added
568 http://rt.cpan.org/Ticket/Display.html?id=41028
570 - write out the image size in bytes field of a BMP correctly.
571 http://rt.cpan.org/Ticket/Display.html?id=41406
573 - add limited tests for Imager::ExtUtils
575 - make Imager::ExtUtils->includes use an absolute path, since
576 a relative path could cause failures using Inline::C.
577 http://rt.cpan.org/Ticket/Display.html?id=37353
579 - re-arrange the POD for Imager::Font::BBox:
580 - mark total_width(), pos_width(), end_offset() obsolete, since
581 they're mostly for backwards compatibility
582 - group width methods and height methods
583 https://rt.cpan.org/Ticket/Display.html?id=39999
585 Imager 0.65 - 20 May 2008
590 - In some cases when an error occurs reading those parts of a JPEG
591 file after the image the scan-line buffer could be freed a second
592 time. In cases where the the error occured while reading the image
593 data it's possible that the buffer could have leaked.
594 Thanks to Gabriel Vasseur for reporting this and help in tracking
597 - the gif_screen_height tag was overriding the screen width and being
598 ignored for the screen height when present.
599 https://rt.cpan.org/Public/Bug/Display.html?id=35568
601 Imager 0.64 - 23 April 2008
604 This is a bug fix release. This includes a fix for a possible
609 - Possible security issue: The floating point sample path for image
610 based fills had a buffer overflow. This would overwrite the end of
611 a malloc()ed buffer with double precision floats.
612 http://rt.cpan.org/Ticket/Display.html?id=35324
615 - check that the result of fileno($fh) is defined rather than simply
616 true when read() or write() is supplied with an fh parameter.
617 http://rt.cpan.org/Ticket/Display.html?id=35139
619 - i_scale_axis() wasn't checking the result of i_img_new_ch()
620 resulting in a SIGSEGV when attempting to scale an image to a size
621 too large to fit in memory. This is a NULL pointer access issue,
622 not a buffer overflow.
623 Added a check for the failure.
624 scale_calculate() (and hence scale()) will now fail if any of the
625 scale size parameters are a reference.
626 http://rt.cpan.org/Ticket/Display.html?id=35172
628 - Regression: filling a greyscale image with a hatch used the wrong
629 color channels from the supplied fg/bg colors.
630 https://rt.cpan.org/Ticket/Display.html?id=35278
632 - fixed a related problem for image fills.
634 Imager 0.63 - 7 April 2008
637 This release primarily contains changes to improve ease of use -
638 rather than you having to convert images to the appropriate number of
639 channels, Imager handles it internally. How to handle drawing colors
640 and the default combine mode is a thornier problem left for some other
643 - the font libraries are now only initialized when needed.
644 http://rt.cpan.org/Ticket/Display.html?id=28825
646 - moved the imtoc.perl code into Imager::Preprocess
648 - paste() and rubthrough() now adapt the source image data to the
649 destination, so you can now safely paste/rubthrough from greyscale
650 images to color images or back, or from alpha channel images to
651 noalpha channels or back.
652 https://rt.cpan.org/Ticket/Display.html?id=30908
654 - rubthrough() now falls back to pasting when the source doesn't have
655 an alpha channel. This effectively treats the source as having a
656 max alpha channel, the right thing to do.
657 http://rt.cpan.org/Ticket/Display.html?id=29944
659 - re-worked most of the area filling code to use a common set of
660 functions when filling.
661 Corrected normal combine mode.
662 Rewrote most of the combine modes to match the way the SVG draft
663 defines them with respect to a translucent source and destination.
664 Added tests for translucent source and destination.
665 Added tests to check 8-bit/sample and double/sample combines work
667 https://rt.cpan.org/Ticket/Display.html?id=29879
669 - writing a 2 or 4 channel image to a JPEG file will now write that
670 image as if composited against a background, black by default,
671 overridable with the i_background tag/parameter.
672 https://rt.cpan.org/Ticket/Display.html?id=29876
674 - writing a 2 or 4 channel image to a PGM/PPM file will now write
675 that image as if composited against a background, black by default,
676 overridable with the i_background tag/parameter.
677 http://rt.cpan.org/Ticket/Display.html?id=30074
679 - writing a 2 or 4 channel image to a BMP file will now write that
680 image as if composited against a background, black by default,
681 overridable with the i_background tag/parameter.
682 http://rt.cpan.org/Ticket/Display.html?id=30075
686 - Imager::Matrix2d->translate() now only requires one of the x or y
688 http://rt.cpan.org/Ticket/Display.html?id=29937
690 - mixing qtype scaling now sets all channels of a pixel to zero if
691 the pixel has zero coverage (zero alpha). This should produce more
692 compressible output files.
693 http://rt.cpan.org/Ticket/Display.html?id=32324
695 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
697 https://bugzilla.redhat.com/show_bug.cgi?id=166254
698 I'm not changing the #! lines of the sample code, since it's sample
699 code, not intended for installation.

702 - some TGA images weren't being detected correctly as TGA images
703 https://rt.cpan.org/Ticket/Display.html?id=32925
705 - handling of the left-over bit for 16-bit/pixel TGA images has been
706 changed to match the behaviour of the GIMP. Previously the bit
707 being set was treated as an opaque pixel, but one user reported a
708 problem with loading such an image. I haven't been able to find any
709 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
710 I'll match it's behaviour. See issue 114913 in the GIMP's
712 http://rt.cpan.org/Ticket/Display.html?id=32926
714 Imager 0.62 - 10 December 2007
717 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
718 to /path under your home directory.
719 http://rt.cpan.org/Ticket/Display.html?id=29484
721 - the old dynaload code used Mach API functions to load dynamic
722 libraries on Mac OS X. These APIs have been deprecated in OS X
723 10.5 and were causing some build problems.
724 So henceforth Imager uses the dlopen() family of functions, and you
725 will need version 10.3 or later of OS X.
727 - added the det() function to the transform2() engine.
728 added the sample quad_to_square.pl
729 Courtesy Richard Fairhurst.
730 http://rt.cpan.org/Ticket/Display.html?id=31244
734 - samples/gifscale.pl sourced the base value for gif_top from
736 Thanks to Eleneldil G. Arilou for pointing this out.
738 - t/t82inline.t no longer loads B at runtime, to work around a bug
739 in some 5.005_0[45] installations.
740 http://rt.cpan.org/Ticket/Display.html?id=30508
742 - work around Module::Depends::Intrusive bug #21229
743 http://rt.cpan.org/Ticket/Display.html?id=30520
745 - the hardinvert filter no-longer inverts the alpha channel.
746 http://rt.cpan.org/Ticket/Display.html?id=30002
748 - the hardinvert filter now supports large samples
750 Imager 0.61_02 - 28 November 2007
753 - major TIFF support re-work
754 http://rt.cpan.org/Ticket/Display.html?id=20329
756 - added a C level image interface for accessing samples from 1-32
757 bits, exposed this at the perl level in getsamples()
759 - the conv filter now works at floating point precision for high bit
762 - added is_bilevel method to test whether an image should be written as
763 a bilevel image if the image format supports it.
765 - added -log-stderr as an Imager import list option
767 - added some important types to Imager::APIRef
769 - added test_image_double() to Imager::Test
773 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
776 - the scale() method with qtype mixing now handles images with an
777 alpha channel correctly.
779 - fixed a broken link from the "animated GIF" entry in the concept index.
780 Thanks to Slaven Rezic.
781 http://rt.cpan.org/Ticket/Display.html?id=30889
783 - on some perl's the infix expression parser test would fail due to
784 actions in the grammar returning false. Made sure all actions return
786 Thanks to Richard Fairhurst for spending a lot of time in tracking
788 http://rt.cpan.org/Public/Bug/Display.html?id=29562
790 Imager 0.61 - 5 November 2007
793 - added samples/gifscale.pl, which adjusts the screen size/position tags
794 when scaling an animated gif
795 http://rt.cpan.org/Ticket/Display.html?id=27591
799 - correct handling of sz in matrix_transform() - this should allow
800 perspective type transformations to work now.
801 http://rt.cpan.org/Ticket/Display.html?id=29936
803 - prevent a cast to integer warning on x64 builds in datatypes.c
804 also fixed some other type warnings
805 https://rt.cpan.org/Ticket/Display.html?id=30204
807 - some sub-directory tests depended on files produced by the parent
809 http://rt.cpan.org/Ticket/Display.html?id=30203
811 - Imager::Font::Wrap doesn't correctly set savepos
812 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
813 http://rt.cpan.org/Ticket/Display.html?id=29771
815 - test 171 in t/t01introvert.t was failing on perls configured to
817 http://rt.cpan.org/Ticket/Display.html?id=29413
819 - the code for the transform2() uminus operator was missing a break.
820 Added tests for better code coverage of the ops.
821 http://rt.cpan.org/Ticket/Display.html?id=29296
823 - the SGI RLE compression code could overflow its compression buffer
824 http://rt.cpan.org/Ticket/Display.html?id=30334
826 - the 32-bit output function used by the SGI code only handled values
827 under 0x10000. This was most noticable when writing large RLE images.
828 http://rt.cpan.org/Ticket/Display.html?id=30335
830 - validate chan_count for chans == NULL for each of the i_gsamp()
832 http://rt.cpan.org/Ticket/Display.html?id=28985
834 - attempt to work around the test failure at
835 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
836 http://rt.cpan.org/Ticket/Display.html?id=29562
838 - improve the error messages produced when attempting to read or write
839 an unknown image file format.
840 http://rt.cpan.org/Ticket/Display.html?id=30103
842 - improve the transform2() documentation
843 http://rt.cpan.org/Ticket/Display.html?id=29267
845 - correctly generate the author key in META.yml
846 http://rt.cpan.org/Ticket/Display.html?id=30377
848 - correctly blend a rotated (or matrix_transformed()) image when
849 performing interpolation in the presence of an alpha channel.
850 Also corrected the centring of the rotated image on the output
853 Imager 0.60 - 30 August 2007
856 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
857 now has full SGI RGB image format, including RLE and 16-bit/sample
859 https://rt.cpan.org/Ticket/Display.html?id=8666
861 - logging functions are now available in the API
863 - applied Gabriel Vasseur's patch
864 added documentation, further tests, and support for greyscale images
865 Obviously problems are my fault :)
866 https://rt.cpan.org/Ticket/Display.html?id=28142
868 - the mask for ICO/CUR images is now applied as an alpha channel to
869 the returned image. For the old behaviour, supply ico_masked => 0
870 to read() or read_multi(). This should be less confusing when
871 using Imager as a general image processor.
872 https://rt.cpan.org/Ticket/Display.html?id=29001
876 - in some cases it's possible for giflib/libungif to return color
877 indexes outside the range of colors defined by the image's palette.
878 We now expand the palette to match the indexes used.
879 Thanks to Gabriel Vasseur for reporting this.
881 - fixed various memory leaks that could occur when failing to read png,
882 jpeg, bmp or tga files.
884 - to avoid confusion, channels not present in the image are returned as
885 zero by getscanline(). This has no effect on the C level i_glin()
886 and i_glinf() API functions which continue to not set the unused
889 - the convert() method now returns an image of the same sample size as
891 https://rt.cpan.org/Ticket/Display.html?id=28492
893 - remove repeated text in Imager::Files
894 http://rt.cpan.org/Ticket/Display.html?id=27589
896 - be even more explicit that scale() and friends don't modify the source
897 image, but return a new image.
898 http://rt.cpan.org/Ticket/Display.html?id=28570
900 - improve the error message from errstr() when you try to load a font
901 for which the driver hasn't been built in Imager.
902 http://rt.cpan.org/Ticket/Display.html?id=27571
904 - transparency is now enabled by default when writing GIF images
905 http://rt.cpan.org/Ticket/Display.html?id=27615
907 - Imager would not load on Windows 98
908 http://rt.cpan.org/Ticket/Display.html?id=27653
910 Imager 0.59 - 14 June 2007
915 - fixes a regression introduced by the fixes for RT 11972
916 http://rt.cpan.org/Ticket/Display.html?id=27546
918 - cropping outside the image would return an Imager object with
919 no low-level image object, instead of returning false.
920 Fixed by: Philip Gwyn (Leolo)
921 http://rt.cpan.org/Ticket/Display.html?id=27509
923 Imager 0.58 - 16 May 2007
926 No significant changes from 0.57_01.
928 Imager 0.57_01 - 11 May 2007
931 - added to_rgb16 to produce a 16-bit/sample version of an image
933 - improve freetype 1.x text output efficiency
937 - search another place for rgb.txt, and check all the places
938 Imager::Color checks when deciding whether to skip testing it
939 http://rt.cpan.org/Ticket/Display.html?id=26064
941 - use a convolution kernel size based on the stddev rather than a
942 fixed size when performing a gaussian blur
943 http://rt.cpan.org/Ticket/Display.html?id=25645
945 - document the difference() method's mindist parameter, and debug it.
947 - put the Imager release number in the Inline::C generated code to
948 regenerate Inline code when a new release of Imager is installed.
949 http://rt.cpan.org/Ticket/Display.html?id=26278
951 - fix rendering on alpha channel images for the FreeType 1.x driver.
952 http://rt.cpan.org/Ticket/Display.html?id=11972
954 - fix rendering on alpha channel images for the T1lib driver.
955 http://rt.cpan.org/Ticket/Display.html?id=11972
957 - reworked library probing, we can now set more than one probe
958 function for a library. Disabled the default (non-freetype-config)
959 library probe and added an extra probe function that searches for
960 both ft2build.h and whatever it includes, and adds -I as needed.
961 Hopefully this will fix build problems like

963 http://rt.cpan.org/Ticket/Display.html?id=26086
965 Imager 0.57 - 30 Apr 2007
968 This is a maintenence release fixing a security issue in Imager.
970 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
971 overflow in malloced memory. There will be further discussion of
972 this issue in the ticket below.
973 http://rt.cpan.org/Ticket/Display.html?id=26811
974 CVE-2007-2459 CVE-2007-2413
975 The descriptions at cve.mitre.org varied in quality, please see the
976 ticket at rt.cpan.org for a more accurate description of the issue.
978 Imager 0.56 - 1 Apr 2007
981 - added support for reading 16-bit/sample PGM/PPM images
983 - added support for writing 16-bit/sample PGM/PPM images
985 - improved performance of reading PBM/PGM/PPM images
987 - added support for writing PBM images if the image is paletted and
988 contains only black and white
990 - added a new make_colors value - "mono"
992 - switched from the svn log Changes to a manual Changes to reduce
995 - new sample code - samples/flasher.pl
999 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
1000 was returning an image object with an extra reference, this
1001 resulted in a memory leak.
1002 http://rt.cpan.org/Ticket/Display.html?id=24992
1004 - fix rendering on alpha channel images for the FreeType 2.x driver
1005 http://rt.cpan.org/Ticket/Display.html?id=11972
1007 - reading bmp files now consitently handles short reads. You can now
1008 supply a parameter to treat a short read as successful and set
1010 http://rt.cpan.org/Ticket/Display.html?id=8426
1012 - previously, reading ASCII PBM files required spaces between samples,
1013 even though the format doesn't require that
1015 - improved documentation of the unsharpmask filter (I hope)
1016 http://rt.cpan.org/Ticket/Display.html?id=25531
1018 - force flushing of the output from i_tt_dump_names() and test output
1019 in t/t35ttfont.t to prevent output from being mixed up.
1020 https://rt.cpan.org/Ticket/Display.html?id=24859
1022 - rewrite a conditional expression as an if() to hopefully work around
1023 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
1024 https://rt.cpan.org/Ticket/Display.html?id=25561
1026 - avoid Data::Dumper in regops.perl to support older releases of perl
1027 https://rt.cpan.org/Ticket/Display.html?id=24391
1029 Imager 0.55 - 16 Dec 2006
1032 This is primarily a bug fix release.
1034 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1036 There is one new feature:
1038 - the Win32 font driver now supports UTF8 (RT 22166)
1039 http://www.cpanforum.com/threads/3276
1040 http://rt.cpan.org/Ticket/Display.html?id=22166
1042 Several bugs were fixed:
1044 - the string() method would not output the string "0"
1045 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1047 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1048 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1050 - the gif_disposal and gif_user_input tags weren't being read from
1052 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1054 - gif.c was failing to build under MSVC
1055 http://rt.cpan.org/Ticket/Display.html?id=23922
1057 - in some cases strings passed to the string() method were treated as
1058 terminated by NUL (chr 0)
1059 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1061 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1062 that's the default build name for zlib on Win32.
1063 http://rt.cpan.org/Ticket/Display.html?id=23064
1065 - search $Config{incpath} for headers too, which we should have been
1068 Win32 font driver fixes:
1070 - the global descent value from bounding box was the wrong sign
1071 http://www.cpanforum.com/threads/3276
1073 - if the first or last glyph overflowed the left or right side of the
1074 advance width they would be clipped
1077 Imager 0.54 - 14 Sep 2006
1080 This is primarily a feature release:
1082 - a new qtype value 'mixing' has been added to the scale()
1083 method. This is faster than 'normal', slower than 'preview'. This
1084 is based on the method used by pnmscale, and seems to produce less
1085 blurry results than normal.
1086 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1088 - the rubthrough() method can now render onto images with an alpha
1090 http://rt.cpan.org/Ticket/Display.html?id=20678
1092 - the read_multi() method now falls back to calling doing a single
1093 image read via the read() method and write_multi() will now fall
1094 back to calling write() if a single image is supplied. This means
1095 you can simply call the read_multi() or write_multi() functions
1096 without having to check if the type is formatted by that method.
1097 http://rt.cpan.org/Ticket/Display.html?id=19457
1098 http://rt.cpan.org/Ticket/Display.html?id=19458
1100 - the GIF loop extension can now be written. If you don't have
1101 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1103 http://rt.cpan.org/Ticket/Display.html?id=21185
1105 - getscanline() and setscanline() can now read/write palette index
1106 based data from/to the image for paletted images, by setting type to
1108 http://rt.cpan.org/Ticket/Display.html?id=20338
1110 - we no longer hassle you to disable GIF support
1111 http://rt.cpan.org/Ticket/Display.html?id=20687
1113 - minor documentation fixes
1116 Imager 0.53 - 26 Jul 2006
1119 This is a bugfix release.
1121 Some test code was left in a code path not covered by the test
1122 suite. A test was added to cover this code path and the test code was
1124 http://rt.cpan.org/Public/Bug/Display.html?id=20705
1127 Imager 0.52 - 25 Jul 2006
1130 This is primarily a feature release, but contains a fair few bug
1131 fixes, new features:
1133 - ability to read and write MS Windows ICO and CUR files
1135 - you can now add file format plugins to support new file formats
1137 - add POD coverage tests
1139 - setcolors() and addcolors() now accept color names and so on
1140 instead of requiring Imager::Color objects.
1141 http://rt.cpan.org/Ticket/Display.html?id=20056
1143 - flood_fill() can now fill to a specified border color instead of
1144 just to the area the same color as the seed.
1145 http://rt.cpan.org/Ticket/Display.html?id=19618
1150 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1151 calculating the advance width.
1152 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1154 - bounding_box for the T1 driver wasn't including leading and
1155 trailing spaces in the bounding box as the other drivers did, it also
1156 produced strange results for empty strings or strings containing only
1159 - when reading CMYK jpeg images they were being transferred to the
1160 image object as is, producing a four channel image. It only looked ok
1161 due to an old still unfixed Photoshop bug. We now convert from the
1162 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1163 http://rt.cpan.org/Ticket/Display.html?id=20416
1165 - reading a CYMK TIFF would result in a 4 channel image, reading any
1166 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1168 http://rt.cpan.org/Ticket/Display.html?id=20415
1170 - added /usr/local/include to the default include search path, since
1171 we were already searching /usr/local/lib for libraries.
1173 And various minor fixes and documentation updates.
1176 Imager 0.51 - 23 Apr 2006
1179 - fix a validation bug when processing JPEG EXIF data that can cause
1181 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1183 - fix mis-processing of the src_maxx and src_maxy parameters of the
1185 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1187 - fix a problem in Imager's "smart" handling of the color parameter
1189 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1192 Imager 0.50 - 29 Mar 2006
1195 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1196 or 4 channel image to jpeg or a 2 channel image to tga where the
1197 output is an in-memeory buffer.
1198 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1200 - fixes an incorrect pointer parameter in the PNG code
1201 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1203 - skip Inline::C tests when building in a directory with spaces
1204 http://rt.cpan.org/Public/Bug/Display.html?id=18049
