1 Imager release history. Older releases can be found in Changes.old
6 - Imager no longer inherits from Exporter (unless you're running an
11 - re-work, document and test Imager's logging facility.
12 https://rt.cpan.org/Ticket/Display.html?id=65227
14 - fix META.yml testing and the generated META.yml
15 https://rt.cpan.org/Ticket/Display.html?id=65235
17 - test and add error reporting to to_*() family methods
19 - add to_rgb_double() method.
20 https://rt.cpan.org/Ticket/Display.html?id=65101
22 - Imager no longer exports anything by default
23 https://rt.cpan.org/Ticket/Display.html?id=65228
25 Imager 0.83 - 21 May 2011
30 - diag() the error message on failure for some TIFF tests that are
31 failing on a Solaris smoker.
32 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
34 Imager 0.82_01 - 17 May 2011
37 Dev release, in case the compose tests are too sensitive.
41 - Imager::Font::T1 incorrectly checked for absolute filename under
42 Win32. Thanks to kmx for the report and fix.
43 https://rt.cpan.org/Ticket/Display.html?id=67963
45 - compose() with the target, source or mask position off the top or
46 left of the target image didn't clip the source image correctly.
47 https://rt.cpan.org/Ticket/Display.html?id=67220
49 - compose() now returns a useful error message on a non-positive
52 - compose.im now at 100% test coverage. (As opposed to, umm, much,
55 Imager 0.82 - 14 Mar 2011
60 - eliminate calls to i_has_format() from the test suite, since it's
61 no longer a useful way to check for file format support. Eliminate
62 i_has_format() from the functions exposed via XS.
63 https://rt.cpan.org/Ticket/Display.html?id=65863
65 - eliminate calls to note(), which isn't in the (very old) version of
66 Test::More we have as a pre-requisite. note() is modern enough
67 that I don't feel a need to require a Test::More upgrade for it.
68 https://rt.cpan.org/Ticket/Display.html?id=65864
70 - skip the threads tests on Test::More 2.00_*
71 https://rt.cpan.org/Ticket/Display.html?id=65812
73 - add an (unshipped) test to check Imager's internal POD links
74 https://rt.cpan.org/Ticket/Display.html?id=65749
76 - improve the library detection summary
77 https://rt.cpan.org/Ticket/Display.html?id=9675
79 - increase the version of Imager::Font::Type1 so that upgrades don't
80 downgrade the version in this file.
81 https://rt.cpan.org/Ticket/Display.html?id=66250
83 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
84 that option for the directories that would normally go in
85 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
86 https://rt.cpan.org/Ticket/Display.html?id=65955
88 Imager 0.81 - 14 Feb 2011
91 - added coverage tests for masked images (maskimg.c @100% test coverage)
93 - add hsv() method to Imager::Color
94 Thanks to Leolo (Philip Gwyn)
95 https://rt.cpan.org/Ticket/Display.html?id=65385
97 - split libt1 Type 1 font support into a sub-module
98 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
100 - add a preload() class method for use in forking servers, and to
101 work around limitations in PAR.
102 https://rt.cpan.org/Ticket/Display.html?id=65665
106 - paletted writes to a masked image are now masked correctly.
107 Revealed by new coverage tests.
109 - update the filter plugin documentation.
110 https://rt.cpan.org/Ticket/Display.html?id=56513
112 - add the matrix() method to Imager::Matrix2d to allow creation of a
113 matrix with specified co-efficients. You can now multiple an
114 Imager::Matrix2d object by a 9 element array ref or a number.
115 https://rt.cpan.org/Ticket/Display.html?id=29938
117 - really fix loading TTF fonts with FT2 when FT1 isn't available.
118 Thanks to Leolo (Philip Gwyn)
119 https://rt.cpan.org/Ticket/Display.html?id=65386
120 https://rt.cpan.org/Ticket/Display.html?id=62855
122 - make sure each test script that needs testout/ creates it.
123 https://rt.cpan.org/Ticket/Display.html?id=65088
125 - handle a slightly different warning from libtiff 4.x
126 https://rt.cpan.org/Ticket/Display.html?id=65268
128 - the sat transform2() op returned an incorrect saturation.
129 https://rt.cpan.org/Ticket/Display.html?id=65391
131 Imager 0.80 - 17 Jan 2011
134 - added coverage tests for Imager::Fountain and Imager::Color::Float
136 - Imager is now maintained in git
137 http://git.imager.perl.org/imager.git
138 git://git.imager.perl.org/imager.git
142 - images with an translucent alpha channel were not scaled correctly
143 by the default (qtype=normal) scaling method.
144 https://rt.cpan.org/Public/Bug/Display.html?id=63922
146 - Imager::Color::Float now translates "#FFFFFF" to white instead of
147 just a little darker.
149 - make the default color map build algorithm "mediancut". This
150 changes the default color map builder for writing GIFs back to what
151 it was in 0.77, reverting a performance regression.
152 https://rt.cpan.org/Ticket/Display.html?id=64785
154 - handle failure to create a masked image correctly
156 Imager 0.79 - 10 Dec 2010
159 - add Imager::Test to the POD coverage tests and document the missing
162 - the convert() method now optimizes the case where all output
163 channels are either 0, sourced from a single input channel or 1.
164 This significantly speeds up presets like "addalpha", "green".
165 https://rt.cpan.org/Ticket/Display.html?id=51254
167 - add wiggle.pl sample, as suggested by Dan Oppenheim.
169 - add the combine() method to combine channels from multiple source
170 images into a new image
171 https://rt.cpan.org/Ticket/Display.html?id=11872
175 - treat the co-efficients for convert() as doubles instead of floats.
177 - If a higher (earlier) priority font handler failed to load, that
178 would crash preventing loading of later font handlers.
179 https://rt.cpan.org/Ticket/Display.html?id=62855
181 - parse defines from the options returned by pkg-config --cflags
182 https://rt.cpan.org/Ticket/Display.html?id=63223
184 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
185 included in the tarball. They are now included.
187 Imager 0.78 - 4 Oct 2010
192 - don't access deprecated members of the png_structp.
193 https://rt.cpan.org/Ticket/Display.html?id=60242
195 - document that using color objects is faster than supplying colors
197 https://rt.cpan.org/Ticket/Display.html?id=61047
199 - Imager::Probe now accepts array references for incpath and libpath.
200 https://rt.cpan.org/Ticket/Display.html?id=60244
202 Imager 0.77_02 - 27 Sep 2010
205 - moved Win32, FreeType 2 font support into sub-modules.
206 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
207 Uses Imager::Probe now.
208 https://rt.cpan.org/Public/Bug/Display.html?id=61328
210 - tested successfully with jpeg-8b
211 https://rt.cpan.org/Ticket/Display.html?id=60221
215 - from _01: look for missing file support test files in the right
218 - flood_fill() wouldn't fill the right side of a single scan-line
220 Thanks to Nicolas Roggli for reporting this.
222 - flood_fill wouldn't fill to the left edge of the image if the
223 starting line didn't reach the left edge.
224 Thanks to Nicolas Roggli for reporting this.
226 Imager 0.77_01 - 13 Sep 2010
229 - add each library-directory/pkgconfig/ to the pkg-config search path
231 Thanks to Justin Davis.
232 https://rt.cpan.org/Ticket/Display.html?id=60491
234 - moved GIF, TIFF, JPEG file handling code into sub-modules in
235 preparation for separate distribution.
236 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
238 - optimize filled box drawing (color, not fill)
242 - Imager::Probe was calling ExtUtils::Liblist to initialize
243 LD_RUN_PATH supplying an undefined value rather than the found
244 directory. Thanks to Justin Davis.
245 https://rt.cpan.org/Ticket/Display.html?id=60491
247 - only prepend ./ to font filenames when passing them to T1Lib and
248 then only when it would use its search mechanisms.
249 https://rt.cpan.org/Ticket/Display.html?id=60509
251 - fix the cache check for the X rgb.txt loader. This is typically
252 used for color translation on Unix-like systems, and the fix
253 improves performance of supplying colors by name by about 80 times.
254 Test code that managed 3400 10x10 pixel boxes/second sped up to
257 - clarify that Imager doesn't write EXIF metadata to images.
258 https://rt.cpan.org/Ticket/Display.html?id=60637
260 - Imager::Probe can now search subdirectories under its include path.
261 Used by the PNG Makefile.PL to find headers and libraries when they
262 aren't in the base directory, as in cygwin.
263 https://rt.cpan.org/Ticket/Display.html?id=60635
265 Imager 0.77 - 11 Aug 2010
268 I don't want Imager::File::PNG indexed as part of Imager, but forgot
269 to update the META.yml before updating the version.
271 - don't index Imager::File::PNG as part of Imager
273 - add resources to META.yml
275 Imager 0.76 - not released
280 - the align_string() method would ignore a string of "0" due to a
282 Thanks to Maurice Height for reporting this.
283 https://rt.cpan.org/Ticket/Display.html?id=60199
285 Imager 0.75_03 - 09 Aug 2010
290 - read_types() and write_types() would include png when it wasn't
291 available due to a problem with the %formats tie
293 - handle dependent libraries correctly (eg -lpng requiring -lz) in
294 the code run phase of library probing.
296 Imager 0.75_02 - 07 Aug 2010
301 - add file missing from MANIFEST, which was causing TIFF failures.
303 Imager 0.75_01 - 06 Aug 2010
306 Test release for the new PNG probe.
308 - added the ability to read multiple-image PNM files.
309 Note that unlike the pbm/pgm/ppm specification this accepts mixed
310 format files and allows white space padding between files.
311 Thanks to Philip Gwyn (Leolo) for this patch.
313 - moved the PNG file handling code into a sub-module in preparation
314 for separate distribution.
315 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
316 Also helps avoid complications from -I/-L compile/link options from
321 - Imager->new(data => $data) didn't try to process image file data in
323 https://rt.cpan.org/Ticket/Display.html?id=58761
325 - t/t50basicoo.t no longer depends on the other tests to generate its
327 https://rt.cpan.org/Ticket/Display.html?id=9798
328 Also, it wasn't testing pnm (pnm vs ppm mix-up)
330 - update the documentation of hardinvert to match the change in 0.62.
331 https://rt.cpan.org/Ticket/Display.html?id=59785
333 - added hardinvertall filter which also inverts the alpha channel
336 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
337 the probe can find the library for the test run.
338 https://rt.cpan.org/Ticket/Display.html?id=57518
340 Imager 0.75 - 20 Jun 2010
343 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
348 - an opacity fill based on a fountain fill would segfault when
349 filling an 8-bit/sample image.
351 - merge thickline branch polygon fix
352 https://rt.cpan.org/Ticket/Display.html?id=43518
354 Imager 0.74 - 7 May 2010
359 - read_multi() didn't handle a missing file format library correctly,
360 aborting on failing to call i_readgif_multi_wiol() or
361 i_readtiff_multi_wiol().
363 - fix spelling errors patched by Debian
364 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
366 - add an (unshipped) author test to spellcheck Imager's POD.
368 - update the TIFF file format documentation
369 https://rt.cpan.org/Ticket/Display.html?id=56510
371 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
373 Imager 0.73 - 15 Mar 2010
376 - implement outline circles, both anti-aliased and not
377 https://rt.cpan.org/Ticket/Display.html?id=19755
379 - a combine => "none" fill to a 1 or 3 channel image would produce
380 the incorrect colour.
382 Imager 0.72 - 09 Dec 2009
385 Bump version for release, since 0.71_03 is stable with CPAN testers.
387 Imager 0.71_03 - 5 Dec 2009
390 - further adjust the threads test so it only performs the tests on
391 perls where it's expected to work, and only if the threads module
394 Imager 0.71_02 - 1 Dec 2009
397 - adjust the way we load the threads module for the threads test so
398 it works with non-threaded perls
400 Imager 0.71_01 - 30 Nov 2009
405 - use scanline oriented operations to flip images instead of pixel
407 https://rt.cpan.org/Ticket/Display.html?id=39278
409 - use double/sample operations to flip large sample images instead of
410 8-bit sample operations.
411 https://rt.cpan.org/Ticket/Display.html?id=39280
414 https://rt.cpan.org/Ticket/Display.html?id=51874
416 - prevent double-frees when someone creates Imager objects and then
417 creates a thread. Note: this just handles some simple cases,
418 Imager doesn't support perl threads, and isn't likely to.
419 https://rt.cpan.org/Ticket/Display.html?id=52268
421 Imager 0.71 - 16 Nov 2009
424 - add the opacity fill type - an adaptor that modifies the opacity of
429 - the conv filter now enforces that the sum of the coefficients is
430 non-zero. Also, rather than skipping pixels off the edge off the
431 edge of the image, the closest edge pixel is used. Previously
432 dividing by the zero sum of coefficients could cause invalid
433 results or runtime exceptions.
434 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
437 Imager 0.70 - 21 Sep 2009
442 - release image row and comments memory on all error returns in gif
445 - handle zero length extensions, previously this would cause a null
447 Thanks to Krzysztof Wojtaś for the test data and fix for this.
449 - an integer division meant that preview scaling to below 1 pixel
450 wide or high (which isn't too useful anyway) was calculating using
451 NaNs on most platforms, and causing an exception on others.
452 Thanks to David Cantrell for producing a backtrace of the crash on
453 his Alpha-NetBSD CPAN test box which made it possible to track this
456 Imager 0.69 - 08 Sep 2009
461 - broken test fix - was attempting to call a function skip_all, when
462 that should be a parameter to plan().
464 - briefly document apidocs.perl, the tool used to build
465 Imager::APIRef and make some minor enhancements
467 - various minor documentation enhancements and fixes.
469 Imager 0.68 - 07 Sep 2009
472 - Imager->new(file => $filename) and other similar incantations will
474 https://rt.cpan.org/Ticket/Display.html?id=48261
478 - avoid using CHECK as a label in Imager::Test
479 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
481 - re-work most image file test files that require a library into
482 separate library present/not present files to remove stupidly long
485 - don't treat rubthrough() outside the bounds of the target image as
487 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
489 Imager 0.67_01 - 02 Sep 2009
494 - correct documentation of default of raw image interleave read
496 https://rt.cpan.org/Ticket/Display.html?id=42074
498 - add raw_ prefix to raw read parameters, though the original names
501 - fail the read if an invalid raw_interleave parameter is supplied
503 - warn if no interleave or raw_interleave parameter is supplied,
504 since the documented default was wrong, and incompatible with the
507 - for reading raw images, if raw_storechannels > raw_datachannels,
508 set the extra channels in the image to 0
510 - when probing for executables like freetype-config, search for .bat
511 and .cmd on MSWin32, as well as .exe.
512 https://rt.cpan.org/Ticket/Display.html?id=49275
514 - re-work the external libraries section of README:
515 - list Debian and Redhat package names for each library
519 - use the new EU::MM META_MERGE facility instead of generating
520 META.yml from scratch
521 https://rt.cpan.org/Ticket/Display.html?id=47888
523 - use Devel::CheckLib (bundled, modified) to check which release of
524 libtiff is installed and reject 3.9.0
525 http://bugzilla.maptools.org/show_bug.cgi?id=2088
526 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
528 Imager 0.67 - 12 Dec 2008
533 - fix a packaging error
535 Imager 0.66 - 12 Dec 2008
538 - 24-bit color .ICO/.CUR files can now be read.
542 - an optimization skipping 0 src alpha values could cause the
543 rubthrough() to read past the end of a buffer.
544 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
546 - corrected a reference leak where writing GIFs would leak memory.
547 This could also happen calling to_paletted().
548 Also documented the underlying long existing feature where the
549 colors parameter is filled with the generated color table and added
551 http://rt.cpan.org/Ticket/Display.html?id=41028
553 - write out the image size in bytes field of a BMP correctly.
554 http://rt.cpan.org/Ticket/Display.html?id=41406
556 - add limited tests for Imager::ExtUtils
558 - make Imager::ExtUtils->includes use an absolute path, since
559 a relative path could cause failures using Inline::C.
560 http://rt.cpan.org/Ticket/Display.html?id=37353
562 - re-arrange the POD for Imager::Font::BBox:
563 - mark total_width(), pos_width(), end_offset() obsolete, since
564 they're mostly for backwards compatibility
565 - group width methods and height methods
566 https://rt.cpan.org/Ticket/Display.html?id=39999
568 Imager 0.65 - 20 May 2008
573 - In some cases when an error occurs reading those parts of a JPEG
574 file after the image the scan-line buffer could be freed a second
575 time. In cases where the the error occured while reading the image
576 data it's possible that the buffer could have leaked.
577 Thanks to Gabriel Vasseur for reporting this and help in tracking
580 - the gif_screen_height tag was overriding the screen width and being
581 ignored for the screen height when present.
582 https://rt.cpan.org/Public/Bug/Display.html?id=35568
584 Imager 0.64 - 23 April 2008
587 This is a bug fix release. This includes a fix for a possible
592 - Possible security issue: The floating point sample path for image
593 based fills had a buffer overflow. This would overwrite the end of
594 a malloc()ed buffer with double precision floats.
595 http://rt.cpan.org/Ticket/Display.html?id=35324
598 - check that the result of fileno($fh) is defined rather than simply
599 true when read() or write() is supplied with an fh parameter.
600 http://rt.cpan.org/Ticket/Display.html?id=35139
602 - i_scale_axis() wasn't checking the result of i_img_new_ch()
603 resulting in a SIGSEGV when attempting to scale an image to a size
604 too large to fit in memory. This is a NULL pointer access issue,
605 not a buffer overflow.
606 Added a check for the failure.
607 scale_calculate() (and hence scale()) will now fail if any of the
608 scale size parameters are a reference.
609 http://rt.cpan.org/Ticket/Display.html?id=35172
611 - Regression: filling a greyscale image with a hatch used the wrong
612 color channels from the supplied fg/bg colors.
613 https://rt.cpan.org/Ticket/Display.html?id=35278
615 - fixed a related problem for image fills.
617 Imager 0.63 - 7 April 2008
620 This release primarily contains changes to improve ease of use -
621 rather than you having to convert images to the appropriate number of
622 channels, Imager handles it internally. How to handle drawing colors
623 and the default combine mode is a thornier problem left for some other
626 - the font libraries are now only initialized when needed.
627 http://rt.cpan.org/Ticket/Display.html?id=28825
629 - moved the imtoc.perl code into Imager::Preprocess
631 - paste() and rubthrough() now adapt the source image data to the
632 destination, so you can now safely paste/rubthrough from greyscale
633 images to color images or back, or from alpha channel images to
634 noalpha channels or back.
635 https://rt.cpan.org/Ticket/Display.html?id=30908
637 - rubthrough() now falls back to pasting when the source doesn't have
638 an alpha channel. This effectively treats the source as having a
639 max alpha channel, the right thing to do.
640 http://rt.cpan.org/Ticket/Display.html?id=29944
642 - re-worked most of the area filling code to use a common set of
643 functions when filling.
644 Corrected normal combine mode.
645 Rewrote most of the combine modes to match the way the SVG draft
646 defines them with respect to a translucent source and destination.
647 Added tests for translucent source and destination.
648 Added tests to check 8-bit/sample and double/sample combines work
650 https://rt.cpan.org/Ticket/Display.html?id=29879
652 - writing a 2 or 4 channel image to a JPEG file will now write that
653 image as if composited against a background, black by default,
654 overridable with the i_background tag/parameter.
655 https://rt.cpan.org/Ticket/Display.html?id=29876
657 - writing a 2 or 4 channel image to a PGM/PPM file will now write
658 that image as if composited against a background, black by default,
659 overridable with the i_background tag/parameter.
660 http://rt.cpan.org/Ticket/Display.html?id=30074
662 - writing a 2 or 4 channel image to a BMP file will now write that
663 image as if composited against a background, black by default,
664 overridable with the i_background tag/parameter.
665 http://rt.cpan.org/Ticket/Display.html?id=30075
669 - Imager::Matrix2d->translate() now only requires one of the x or y
671 http://rt.cpan.org/Ticket/Display.html?id=29937
673 - mixing qtype scaling now sets all channels of a pixel to zero if
674 the pixel has zero coverage (zero alpha). This should produce more
675 compressible output files.
676 http://rt.cpan.org/Ticket/Display.html?id=32324
678 - removed the pointless #! line from lib/Imager/Font/Wrap.pm

681 I'm not changing the #! lines of the sample code, since it's sample
682 code, not intended for installation.
683 http://rt.cpan.org/Ticket/Display.html?id=33408
685 - some TGA images weren't being detected correctly as TGA images
686 https://rt.cpan.org/Ticket/Display.html?id=32925
688 - handling of the left-over bit for 16-bit/pixel TGA images has been
689 changed to match the behaviour of the GIMP. Previously the bit
690 being set was treated as an opaque pixel, but one user reported a
691 problem with loading such an image. I haven't been able to find any
692 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
693 I'll match it's behaviour. See issue 114913 in the GIMP's
695 http://rt.cpan.org/Ticket/Display.html?id=32926
697 Imager 0.62 - 10 December 2007
700 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
701 to /path under your home directory.
702 http://rt.cpan.org/Ticket/Display.html?id=29484
704 - the old dynaload code used Mach API functions to load dynamic
705 libraries on Mac OS X. These APIs have been deprecated in OS X
706 10.5 and were causing some build problems.
707 So henceforth Imager uses the dlopen() family of functions, and you
708 will need version 10.3 or later of OS X.
710 - added the det() function to the transform2() engine.
711 added the sample quad_to_square.pl
712 Courtesy Richard Fairhurst.
713 http://rt.cpan.org/Ticket/Display.html?id=31244
717 - samples/gifscale.pl sourced the base value for gif_top from
719 Thanks to Eleneldil G. Arilou for pointing this out.
721 - t/t82inline.t no longer loads B at runtime, to work around a bug
722 in some 5.005_0[45] installations.
723 http://rt.cpan.org/Ticket/Display.html?id=30508
725 - work around Module::Depends::Intrusive bug #21229
726 http://rt.cpan.org/Ticket/Display.html?id=30520
728 - the hardinvert filter no-longer inverts the alpha channel.
729 http://rt.cpan.org/Ticket/Display.html?id=30002
731 - the hardinvert filter now supports large samples
733 Imager 0.61_02 - 28 November 2007
736 - major TIFF support re-work
737 http://rt.cpan.org/Ticket/Display.html?id=20329
739 - added a C level image interface for accessing samples from 1-32
740 bits, exposed this at the perl level in getsamples()
742 - the conv filter now works at floating point precision for high bit
745 - added is_bilevel method to test whether an image should be written as
746 a bilevel image if the image format supports it.
748 - added -log-stderr as an Imager import list option
750 - added some important types to Imager::APIRef
752 - added test_image_double() to Imager::Test
756 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
759 - the scale() method with qtype mixing now handles images with an
760 alpha channel correctly.
762 - fixed a broken link from the "animated GIF" entry in the concept index.
763 Thanks to Slaven Rezic.
764 http://rt.cpan.org/Ticket/Display.html?id=30889
766 - on some perl's the infix expression parser test would fail due to
767 actions in the grammar returning false. Made sure all actions return
769 Thanks to Richard Fairhurst for spending a lot of time in tracking
771 http://rt.cpan.org/Public/Bug/Display.html?id=29562
773 Imager 0.61 - 5 November 2007
776 - added samples/gifscale.pl, which adjusts the screen size/position tags
777 when scaling an animated gif
778 http://rt.cpan.org/Ticket/Display.html?id=27591
782 - correct handling of sz in matrix_transform() - this should allow
783 perspective type transformations to work now.
784 http://rt.cpan.org/Ticket/Display.html?id=29936
786 - prevent a cast to integer warning on x64 builds in datatypes.c
787 also fixed some other type warnings
788 https://rt.cpan.org/Ticket/Display.html?id=30204
790 - some sub-directory tests depended on files produced by the parent
792 http://rt.cpan.org/Ticket/Display.html?id=30203
794 - Imager::Font::Wrap doesn't correctly set savepos
795 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
796 http://rt.cpan.org/Ticket/Display.html?id=29771
798 - test 171 in t/t01introvert.t was failing on perls configured to
800 http://rt.cpan.org/Ticket/Display.html?id=29413
802 - the code for the transform2() uminus operator was missing a break.
803 Added tests for better code coverage of the ops.
804 http://rt.cpan.org/Ticket/Display.html?id=29296
806 - the SGI RLE compression code could overflow its compression buffer
807 http://rt.cpan.org/Ticket/Display.html?id=30334
809 - the 32-bit output function used by the SGI code only handled values
810 under 0x10000. This was most noticable when writing large RLE images.
811 http://rt.cpan.org/Ticket/Display.html?id=30335
813 - validate chan_count for chans == NULL for each of the i_gsamp()
815 http://rt.cpan.org/Ticket/Display.html?id=28985
817 - attempt to work around the test failure at
818 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
819 http://rt.cpan.org/Ticket/Display.html?id=29562
821 - improve the error messages produced when attempting to read or write
822 an unknown image file format.
823 http://rt.cpan.org/Ticket/Display.html?id=30103
825 - improve the transform2() documentation
826 http://rt.cpan.org/Ticket/Display.html?id=29267
828 - correctly generate the author key in META.yml
829 http://rt.cpan.org/Ticket/Display.html?id=30377
831 - correctly blend a rotated (or matrix_transformed()) image when
832 performing interpolation in the presence of an alpha channel.
833 Also corrected the centring of the rotated image on the output
836 Imager 0.60 - 30 August 2007
839 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
840 now has full SGI RGB image format, including RLE and 16-bit/sample
842 https://rt.cpan.org/Ticket/Display.html?id=8666
844 - logging functions are now available in the API
846 - applied Gabriel Vasseur's patch
847 added documentation, further tests, and support for greyscale images
848 Obviously problems are my fault :)
849 https://rt.cpan.org/Ticket/Display.html?id=28142
851 - the mask for ICO/CUR images is now applied as an alpha channel to
852 the returned image. For the old behaviour, supply ico_masked => 0
853 to read() or read_multi(). This should be less confusing when
854 using Imager as a general image processor.
855 https://rt.cpan.org/Ticket/Display.html?id=29001
859 - in some cases it's possible for giflib/libungif to return color
860 indexes outside the range of colors defined by the image's palette.
861 We now expand the palette to match the indexes used.
862 Thanks to Gabriel Vasseur for reporting this.
864 - fixed various memory leaks that could occur when failing to read png,
865 jpeg, bmp or tga files.
867 - to avoid confusion, channels not present in the image are returned as
868 zero by getscanline(). This has no effect on the C level i_glin()
869 and i_glinf() API functions which continue to not set the unused
872 - the convert() method now returns an image of the same sample size as
874 https://rt.cpan.org/Ticket/Display.html?id=28492
876 - remove repeated text in Imager::Files
877 http://rt.cpan.org/Ticket/Display.html?id=27589
879 - be even more explicit that scale() and friends don't modify the source
880 image, but return a new image.
881 http://rt.cpan.org/Ticket/Display.html?id=28570
883 - improve the error message from errstr() when you try to load a font
884 for which the driver hasn't been built in Imager.
885 http://rt.cpan.org/Ticket/Display.html?id=27571
887 - transparency is now enabled by default when writing GIF images
888 http://rt.cpan.org/Ticket/Display.html?id=27615
890 - Imager would not load on Windows 98
891 http://rt.cpan.org/Ticket/Display.html?id=27653
893 Imager 0.59 - 14 June 2007
898 - fixes a regression introduced by the fixes for RT 11972
899 http://rt.cpan.org/Ticket/Display.html?id=27546
901 - cropping outside the image would return an Imager object with
902 no low-level image object, instead of returning false.
903 Fixed by: Philip Gwyn (Leolo)
904 http://rt.cpan.org/Ticket/Display.html?id=27509
906 Imager 0.58 - 16 May 2007
909 No significant changes from 0.57_01.
911 Imager 0.57_01 - 11 May 2007
914 - added to_rgb16 to produce a 16-bit/sample version of an image
916 - improve freetype 1.x text output efficiency
920 - search another place for rgb.txt, and check all the places
921 Imager::Color checks when deciding whether to skip testing it
922 http://rt.cpan.org/Ticket/Display.html?id=26064
924 - use a convolution kernel size based on the stddev rather than a
925 fixed size when performing a gaussian blur
926 http://rt.cpan.org/Ticket/Display.html?id=25645
928 - document the difference() method's mindist parameter, and debug it.
930 - put the Imager release number in the Inline::C generated code to
931 regenerate Inline code when a new release of Imager is installed.
932 http://rt.cpan.org/Ticket/Display.html?id=26278
934 - fix rendering on alpha channel images for the FreeType 1.x driver.
935 http://rt.cpan.org/Ticket/Display.html?id=11972
937 - fix rendering on alpha channel images for the T1lib driver.
938 http://rt.cpan.org/Ticket/Display.html?id=11972
940 - reworked library probing, we can now set more than one probe
941 function for a library. Disabled the default (non-freetype-config)
942 library probe and added an extra probe function that searches for
943 both ft2build.h and whatever it includes, and adds -I as needed.
944 Hopefully this will fix build problems like
945 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
946 http://rt.cpan.org/Ticket/Display.html?id=26086
948 Imager 0.57 - 30 Apr 2007
951 This is a maintenence release fixing a security issue in Imager.
953 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
954 overflow in malloced memory. There will be further discussion of
955 this issue in the ticket below.
956 http://rt.cpan.org/Ticket/Display.html?id=26811
957 CVE-2007-2459 CVE-2007-2413
958 The descriptions at cve.mitre.org varied in quality, please see the
959 ticket at rt.cpan.org for a more accurate description of the issue.
961 Imager 0.56 - 1 Apr 2007
964 - added support for reading 16-bit/sample PGM/PPM images
966 - added support for writing 16-bit/sample PGM/PPM images
968 - improved performance of reading PBM/PGM/PPM images
970 - added support for writing PBM images if the image is paletted and
971 contains only black and white
973 - added a new make_colors value - "mono"
975 - switched from the svn log Changes to a manual Changes to reduce
978 - new sample code - samples/flasher.pl
982 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
983 was returning an image object with an extra reference, this
984 resulted in a memory leak.
985 http://rt.cpan.org/Ticket/Display.html?id=24992
987 - fix rendering on alpha channel images for the FreeType 2.x driver
988 http://rt.cpan.org/Ticket/Display.html?id=11972
990 - reading bmp files now consitently handles short reads. You can now
991 supply a parameter to treat a short read as successful and set
993 http://rt.cpan.org/Ticket/Display.html?id=8426
995 - previously, reading ASCII PBM files required spaces between samples,
996 even though the format doesn't require that
998 - improved documentation of the unsharpmask filter (I hope)
999 http://rt.cpan.org/Ticket/Display.html?id=25531
1001 - force flushing of the output from i_tt_dump_names() and test output
1002 in t/t35ttfont.t to prevent output from being mixed up.
1003 https://rt.cpan.org/Ticket/Display.html?id=24859
1005 - rewrite a conditional expression as an if() to hopefully work around
1006 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
1007 https://rt.cpan.org/Ticket/Display.html?id=25561
1009 - avoid Data::Dumper in regops.perl to support older releases of perl
1010 https://rt.cpan.org/Ticket/Display.html?id=24391
1012 Imager 0.55 - 16 Dec 2006
1015 This is primarily a bug fix release.
1017 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1019 There is one new feature:
1021 - the Win32 font driver now supports UTF8 (RT 22166)
1022 http://www.cpanforum.com/threads/3276
1023 http://rt.cpan.org/Ticket/Display.html?id=22166
1025 Several bugs were fixed:
1027 - the string() method would not output the string "0"
1028 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1030 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1031 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1033 - the gif_disposal and gif_user_input tags weren't being read from
1035 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1037 - gif.c was failing to build under MSVC
1038 http://rt.cpan.org/Ticket/Display.html?id=23922
1040 - in some cases strings passed to the string() method were treated as
1041 terminated by NUL (chr 0)
1042 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1044 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1045 that's the default build name for zlib on Win32.
1046 http://rt.cpan.org/Ticket/Display.html?id=23064
1048 - search $Config{incpath} for headers too, which we should have been
1051 Win32 font driver fixes:
1053 - the global descent value from bounding box was the wrong sign
1054 http://www.cpanforum.com/threads/3276
1056 - if the first or last glyph overflowed the left or right side of the
1057 advance width they would be clipped
1060 Imager 0.54 - 14 Sep 2006
1063 This is primarily a feature release:
1065 - a new qtype value 'mixing' has been added to the scale()
1066 method. This is faster than 'normal', slower than 'preview'. This
1067 is based on the method used by pnmscale, and seems to produce less
1068 blurry results than normal.
1069 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1071 - the rubthrough() method can now render onto images with an alpha
1073 http://rt.cpan.org/Ticket/Display.html?id=20678
1075 - the read_multi() method now falls back to calling doing a single
1076 image read via the read() method and write_multi() will now fall
1077 back to calling write() if a single image is supplied. This means
1078 you can simply call the read_multi() or write_multi() functions
1079 without having to check if the type is formatted by that method.
1080 http://rt.cpan.org/Ticket/Display.html?id=19457
1081 http://rt.cpan.org/Ticket/Display.html?id=19458
1083 - the GIF loop extension can now be written. If you don't have
1084 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1086 http://rt.cpan.org/Ticket/Display.html?id=21185
1088 - getscanline() and setscanline() can now read/write palette index
1089 based data from/to the image for paletted images, by setting type to
1091 http://rt.cpan.org/Ticket/Display.html?id=20338
1093 - we no longer hassle you to disable GIF support
1094 http://rt.cpan.org/Ticket/Display.html?id=20687
1096 - minor documentation fixes
1099 Imager 0.53 - 26 Jul 2006
1102 This is a bugfix release.
1104 Some test code was left in a code path not covered by the test
1105 suite. A test was added to cover this code path and the test code was
1107 http://rt.cpan.org/Public/Bug/Display.html?id=20705
1110 Imager 0.52 - 25 Jul 2006
1113 This is primarily a feature release, but contains a fair few bug
1114 fixes, new features:
1116 - ability to read and write MS Windows ICO and CUR files
1118 - you can now add file format plugins to support new file formats
1120 - add POD coverage tests
1122 - setcolors() and addcolors() now accept color names and so on
1123 instead of requiring Imager::Color objects.
1124 http://rt.cpan.org/Ticket/Display.html?id=20056
1126 - flood_fill() can now fill to a specified border color instead of
1127 just to the area the same color as the seed.
1128 http://rt.cpan.org/Ticket/Display.html?id=19618
1133 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1134 calculating the advance width.
1135 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1137 - bounding_box for the T1 driver wasn't including leading and
1138 trailing spaces in the bounding box as the other drivers did, it also
1139 produced strange results for empty strings or strings containing only
1142 - when reading CMYK jpeg images they were being transferred to the
1143 image object as is, producing a four channel image. It only looked ok
1144 due to an old still unfixed Photoshop bug. We now convert from the
1145 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1146 http://rt.cpan.org/Ticket/Display.html?id=20416
1148 - reading a CYMK TIFF would result in a 4 channel image, reading any
1149 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1151 http://rt.cpan.org/Ticket/Display.html?id=20415
1153 - added /usr/local/include to the default include search path, since
1154 we were already searching /usr/local/lib for libraries.
1156 And various minor fixes and documentation updates.
1159 Imager 0.51 - 23 Apr 2006
1162 - fix a validation bug when processing JPEG EXIF data that can cause
1164 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1166 - fix mis-processing of the src_maxx and src_maxy parameters of the
1168 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1170 - fix a problem in Imager's "smart" handling of the color parameter
1172 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1175 Imager 0.50 - 29 Mar 2006
1178 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1179 or 4 channel image to jpeg or a 2 channel image to tga where the
1180 output is an in-memeory buffer.
1181 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1183 - fixes an incorrect pointer parameter in the PNG code
1184 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1186 - skip Inline::C tests when building in a directory with spaces
1187 http://rt.cpan.org/Public/Bug/Display.html?id=18049
