1 Imager release history. Older releases can be found in Changes.old
3 Imager 0.82 - unreleased
8 - eliminate calls to i_has_format() from the test suite, since it's
9 no longer a useful way to check for file format support. Eliminate
10 i_has_format() from the functions exposed via XS.
11 https://rt.cpan.org/Ticket/Display.html?id=65863
13 - eliminate calls to note(), which isn't in the (very old) version of
14 Test::More we have as a pre-requisite. note() is modern enough
15 that I don't feel a need to require a Test::More upgrade for it.
16 https://rt.cpan.org/Ticket/Display.html?id=65864
18 - skip the threads tests on Test::More 2.00_*
19 https://rt.cpan.org/Ticket/Display.html?id=65812
21 - add an (unshipped) test to check Imager's internal POD links
22 https://rt.cpan.org/Ticket/Display.html?id=65749
24 - improve the library detection summary
25 https://rt.cpan.org/Ticket/Display.html?id=9675
27 Imager 0.81 - 14 Feb 2011
30 - added coverage tests for masked images (maskimg.c @100% test coverage)
32 - add hsv() method to Imager::Color
33 Thanks to Leolo (Philip Gwyn)
34 https://rt.cpan.org/Ticket/Display.html?id=65385
36 - split libt1 Type 1 font support into a sub-module
37 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
39 - add a preload() class method for use in forking servers, and to
40 work around limitations in PAR.
41 https://rt.cpan.org/Ticket/Display.html?id=65665
45 - paletted writes to a masked image are now masked correctly.
46 Revealed by new coverage tests.
48 - update the filter plugin documentation.
49 https://rt.cpan.org/Ticket/Display.html?id=56513
51 - add the matrix() method to Imager::Matrix2d to allow creation of a
52 matrix with specified co-efficients. You can now multiple an
53 Imager::Matrix2d object by a 9 element array ref or a number.
54 https://rt.cpan.org/Ticket/Display.html?id=29938
56 - really fix loading TTF fonts with FT2 when FT1 isn't available.
57 Thanks to Leolo (Philip Gwyn)
58 https://rt.cpan.org/Ticket/Display.html?id=65386
59 https://rt.cpan.org/Ticket/Display.html?id=62855
61 - make sure each test script that needs testout/ creates it.
62 https://rt.cpan.org/Ticket/Display.html?id=65088
64 - handle a slightly different warning from libtiff 4.x
65 https://rt.cpan.org/Ticket/Display.html?id=65268
67 - the sat transform2() op returned an incorrect saturation.
68 https://rt.cpan.org/Ticket/Display.html?id=65391
70 Imager 0.80 - 17 Jan 2011
73 - added coverage tests for Imager::Fountain and Imager::Color::Float
75 - Imager is now maintained in git
76 http://git.imager.perl.org/imager.git
77 git://git.imager.perl.org/imager.git
81 - images with an translucent alpha channel were not scaled correctly
82 by the default (qtype=normal) scaling method.
83 https://rt.cpan.org/Public/Bug/Display.html?id=63922
85 - Imager::Color::Float now translates "#FFFFFF" to white instead of
88 - make the default color map build algorithm "mediancut". This
89 changes the default color map builder for writing GIFs back to what
90 it was in 0.77, reverting a performance regression.
91 https://rt.cpan.org/Ticket/Display.html?id=64785
93 - handle failure to create a masked image correctly
95 Imager 0.79 - 10 Dec 2010
98 - add Imager::Test to the POD coverage tests and document the missing
101 - the convert() method now optimizes the case where all output
102 channels are either 0, sourced from a single input channel or 1.
103 This significantly speeds up presets like "addalpha", "green".
104 https://rt.cpan.org/Ticket/Display.html?id=51254
106 - add wiggle.pl sample, as suggested by Dan Oppenheim.
108 - add the combine() method to combine channels from multiple source
109 images into a new image
110 https://rt.cpan.org/Ticket/Display.html?id=11872
114 - treat the co-efficients for convert() as doubles instead of floats.
116 - If a higher (earlier) priority font handler failed to load, that
117 would crash preventing loading of later font handlers.
118 https://rt.cpan.org/Ticket/Display.html?id=62855
120 - parse defines from the options returned by pkg-config --cflags
121 https://rt.cpan.org/Ticket/Display.html?id=63223
123 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
124 included in the tarball. They are now included.
126 Imager 0.78 - 4 Oct 2010
131 - don't access deprecated members of the png_structp.
132 https://rt.cpan.org/Ticket/Display.html?id=60242
134 - document that using color objects is faster than supplying colors
136 https://rt.cpan.org/Ticket/Display.html?id=61047
138 - Imager::Probe now accepts array references for incpath and libpath.
139 https://rt.cpan.org/Ticket/Display.html?id=60244
141 Imager 0.77_02 - 27 Sep 2010
144 - moved Win32, FreeType 2 font support into sub-modules.
145 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
146 Uses Imager::Probe now.
147 https://rt.cpan.org/Public/Bug/Display.html?id=61328
149 - tested successfully with jpeg-8b
150 https://rt.cpan.org/Ticket/Display.html?id=60221
154 - from _01: look for missing file support test files in the right
157 - flood_fill() wouldn't fill the right side of a single scan-line
159 Thanks to Nicolas Roggli for reporting this.
161 - flood_fill wouldn't fill to the left edge of the image if the
162 starting line didn't reach the left edge.
163 Thanks to Nicolas Roggli for reporting this.
165 Imager 0.77_01 - 13 Sep 2010
168 - add each library-directory/pkgconfig/ to the pkg-config search path
170 Thanks to Justin Davis.
171 https://rt.cpan.org/Ticket/Display.html?id=60491
173 - moved GIF, TIFF, JPEG file handling code into sub-modules in
174 preparation for separate distribution.
175 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
177 - optimize filled box drawing (color, not fill)
181 - Imager::Probe was calling ExtUtils::Liblist to initialize
182 LD_RUN_PATH supplying an undefined value rather than the found
183 directory. Thanks to Justin Davis.
184 https://rt.cpan.org/Ticket/Display.html?id=60491
186 - only prepend ./ to font filenames when passing them to T1Lib and
187 then only when it would use its search mechanisms.
188 https://rt.cpan.org/Ticket/Display.html?id=60509
190 - fix the cache check for the X rgb.txt loader. This is typically
191 used for color translation on Unix-like systems, and the fix
192 improves performance of supplying colors by name by about 80 times.
193 Test code that managed 3400 10x10 pixel boxes/second sped up to
196 - clarify that Imager doesn't write EXIF metadata to images.
197 https://rt.cpan.org/Ticket/Display.html?id=60637
199 - Imager::Probe can now search subdirectories under its include path.
200 Used by the PNG Makefile.PL to find headers and libraries when they
201 aren't in the base directory, as in cygwin.
202 https://rt.cpan.org/Ticket/Display.html?id=60635
204 Imager 0.77 - 11 Aug 2010
207 I don't want Imager::File::PNG indexed as part of Imager, but forgot
208 to update the META.yml before updating the version.
210 - don't index Imager::File::PNG as part of Imager
212 - add resources to META.yml
214 Imager 0.76 - not released
219 - the align_string() method would ignore a string of "0" due to a
221 Thanks to Maurice Height for reporting this.
222 https://rt.cpan.org/Ticket/Display.html?id=60199
224 Imager 0.75_03 - 09 Aug 2010
229 - read_types() and write_types() would include png when it wasn't
230 available due to a problem with the %formats tie
232 - handle dependent libraries correctly (eg -lpng requiring -lz) in
233 the code run phase of library probing.
235 Imager 0.75_02 - 07 Aug 2010
240 - add file missing from MANIFEST, which was causing TIFF failures.
242 Imager 0.75_01 - 06 Aug 2010
245 Test release for the new PNG probe.
247 - added the ability to read multiple-image PNM files.
248 Note that unlike the pbm/pgm/ppm specification this accepts mixed
249 format files and allows white space padding between files.
250 Thanks to Philip Gwyn (Leolo) for this patch.
252 - moved the PNG file handling code into a sub-module in preparation
253 for separate distribution.
254 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
255 Also helps avoid complications from -I/-L compile/link options from
260 - Imager->new(data => $data) didn't try to process image file data in
262 https://rt.cpan.org/Ticket/Display.html?id=58761
264 - t/t50basicoo.t no longer depends on the other tests to generate its
266 https://rt.cpan.org/Ticket/Display.html?id=9798
267 Also, it wasn't testing pnm (pnm vs ppm mix-up)
269 - update the documentation of hardinvert to match the change in 0.62.
270 https://rt.cpan.org/Ticket/Display.html?id=59785
272 - added hardinvertall filter which also inverts the alpha channel
275 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
276 the probe can find the library for the test run.
277 https://rt.cpan.org/Ticket/Display.html?id=57518
279 Imager 0.75 - 20 Jun 2010
282 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
287 - an opacity fill based on a fountain fill would segfault when
288 filling an 8-bit/sample image.
290 - merge thickline branch polygon fix
291 https://rt.cpan.org/Ticket/Display.html?id=43518
293 Imager 0.74 - 7 May 2010
298 - read_multi() didn't handle a missing file format library correctly,
299 aborting on failing to call i_readgif_multi_wiol() or
300 i_readtiff_multi_wiol().
302 - fix spelling errors patched by Debian
303 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
305 - add an (unshipped) author test to spellcheck Imager's POD.
307 - update the TIFF file format documentation
308 https://rt.cpan.org/Ticket/Display.html?id=56510
310 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
312 Imager 0.73 - 15 Mar 2010
315 - implement outline circles, both anti-aliased and not
316 https://rt.cpan.org/Ticket/Display.html?id=19755
318 - a combine => "none" fill to a 1 or 3 channel image would produce
319 the incorrect colour.
321 Imager 0.72 - 09 Dec 2009
324 Bump version for release, since 0.71_03 is stable with CPAN testers.
326 Imager 0.71_03 - 5 Dec 2009
329 - further adjust the threads test so it only performs the tests on
330 perls where it's expected to work, and only if the threads module
333 Imager 0.71_02 - 1 Dec 2009
336 - adjust the way we load the threads module for the threads test so
337 it works with non-threaded perls
339 Imager 0.71_01 - 30 Nov 2009
344 - use scanline oriented operations to flip images instead of pixel
346 https://rt.cpan.org/Ticket/Display.html?id=39278
348 - use double/sample operations to flip large sample images instead of
349 8-bit sample operations.
350 https://rt.cpan.org/Ticket/Display.html?id=39280
353 https://rt.cpan.org/Ticket/Display.html?id=51874
355 - prevent double-frees when someone creates Imager objects and then
356 creates a thread. Note: this just handles some simple cases,
357 Imager doesn't support perl threads, and isn't likely to.
358 https://rt.cpan.org/Ticket/Display.html?id=52268
360 Imager 0.71 - 16 Nov 2009
363 - add the opacity fill type - an adaptor that modifies the opacity of
368 - the conv filter now enforces that the sum of the coefficients is
369 non-zero. Also, rather than skipping pixels off the edge off the
370 edge of the image, the closest edge pixel is used. Previously
371 dividing by the zero sum of coefficients could cause invalid
372 results or runtime exceptions.
373 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
376 Imager 0.70 - 21 Sep 2009
381 - release image row and comments memory on all error returns in gif
384 - handle zero length extensions, previously this would cause a null
386 Thanks to Krzysztof Wojtaś for the test data and fix for this.
388 - an integer division meant that preview scaling to below 1 pixel
389 wide or high (which isn't too useful anyway) was calculating using
390 NaNs on most platforms, and causing an exception on others.
391 Thanks to David Cantrell for producing a backtrace of the crash on
392 his Alpha-NetBSD CPAN test box which made it possible to track this
395 Imager 0.69 - 08 Sep 2009
400 - broken test fix - was attempting to call a function skip_all, when
401 that should be a parameter to plan().
403 - briefly document apidocs.perl, the tool used to build
404 Imager::APIRef and make some minor enhancements
406 - various minor documentation enhancements and fixes.
408 Imager 0.68 - 07 Sep 2009
411 - Imager->new(file => $filename) and other similar incantations will
413 https://rt.cpan.org/Ticket/Display.html?id=48261
417 - avoid using CHECK as a label in Imager::Test
418 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
420 - re-work most image file test files that require a library into
421 separate library present/not present files to remove stupidly long
424 - don't treat rubthrough() outside the bounds of the target image as
426 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
428 Imager 0.67_01 - 02 Sep 2009
433 - correct documentation of default of raw image interleave read
435 https://rt.cpan.org/Ticket/Display.html?id=42074
437 - add raw_ prefix to raw read parameters, though the original names
440 - fail the read if an invalid raw_interleave parameter is supplied
442 - warn if no interleave or raw_interleave parameter is supplied,
443 since the documented default was wrong, and incompatible with the
446 - for reading raw images, if raw_storechannels > raw_datachannels,
447 set the extra channels in the image to 0
449 - when probing for executables like freetype-config, search for .bat
450 and .cmd on MSWin32, as well as .exe.
451 https://rt.cpan.org/Ticket/Display.html?id=49275
453 - re-work the external libraries section of README:
454 - list Debian and Redhat package names for each library
458 - use the new EU::MM META_MERGE facility instead of generating
459 META.yml from scratch
460 https://rt.cpan.org/Ticket/Display.html?id=47888
462 - use Devel::CheckLib (bundled, modified) to check which release of
463 libtiff is installed and reject 3.9.0
464 http://bugzilla.maptools.org/show_bug.cgi?id=2088
465 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
467 Imager 0.67 - 12 Dec 2008
472 - fix a packaging error
474 Imager 0.66 - 12 Dec 2008
477 - 24-bit color .ICO/.CUR files can now be read.
481 - an optimization skipping 0 src alpha values could cause the
482 rubthrough() to read past the end of a buffer.
483 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
485 - corrected a reference leak where writing GIFs would leak memory.
486 This could also happen calling to_paletted().
487 Also documented the underlying long existing feature where the
488 colors parameter is filled with the generated color table and added
490 http://rt.cpan.org/Ticket/Display.html?id=41028
492 - write out the image size in bytes field of a BMP correctly.
493 http://rt.cpan.org/Ticket/Display.html?id=41406
495 - add limited tests for Imager::ExtUtils
497 - make Imager::ExtUtils->includes use an absolute path, since
498 a relative path could cause failures using Inline::C.
499 http://rt.cpan.org/Ticket/Display.html?id=37353
501 - re-arrange the POD for Imager::Font::BBox:
502 - mark total_width(), pos_width(), end_offset() obsolete, since
503 they're mostly for backwards compatibility
504 - group width methods and height methods
505 https://rt.cpan.org/Ticket/Display.html?id=39999
507 Imager 0.65 - 20 May 2008
512 - In some cases when an error occurs reading those parts of a JPEG
513 file after the image the scan-line buffer could be freed a second
514 time. In cases where the the error occured while reading the image
515 data it's possible that the buffer could have leaked.
516 Thanks to Gabriel Vasseur for reporting this and help in tracking
519 - the gif_screen_height tag was overriding the screen width and being
520 ignored for the screen height when present.
521 https://rt.cpan.org/Public/Bug/Display.html?id=35568
523 Imager 0.64 - 23 April 2008
526 This is a bug fix release. This includes a fix for a possible
531 - Possible security issue: The floating point sample path for image
532 based fills had a buffer overflow. This would overwrite the end of
533 a malloc()ed buffer with double precision floats.
534 http://rt.cpan.org/Ticket/Display.html?id=35324
537 - check that the result of fileno($fh) is defined rather than simply
538 true when read() or write() is supplied with an fh parameter.
539 http://rt.cpan.org/Ticket/Display.html?id=35139
541 - i_scale_axis() wasn't checking the result of i_img_new_ch()
542 resulting in a SIGSEGV when attempting to scale an image to a size
543 too large to fit in memory. This is a NULL pointer access issue,
544 not a buffer overflow.
545 Added a check for the failure.
546 scale_calculate() (and hence scale()) will now fail if any of the
547 scale size parameters are a reference.
548 http://rt.cpan.org/Ticket/Display.html?id=35172
550 - Regression: filling a greyscale image with a hatch used the wrong
551 color channels from the supplied fg/bg colors.
552 https://rt.cpan.org/Ticket/Display.html?id=35278
554 - fixed a related problem for image fills.
556 Imager 0.63 - 7 April 2008
559 This release primarily contains changes to improve ease of use -
560 rather than you having to convert images to the appropriate number of
561 channels, Imager handles it internally. How to handle drawing colors
562 and the default combine mode is a thornier problem left for some other
565 - the font libraries are now only initialized when needed.
566 http://rt.cpan.org/Ticket/Display.html?id=28825
568 - moved the imtoc.perl code into Imager::Preprocess
570 - paste() and rubthrough() now adapt the source image data to the
571 destination, so you can now safely paste/rubthrough from greyscale
572 images to color images or back, or from alpha channel images to
573 noalpha channels or back.
574 https://rt.cpan.org/Ticket/Display.html?id=30908
576 - rubthrough() now falls back to pasting when the source doesn't have
577 an alpha channel. This effectively treats the source as having a
578 max alpha channel, the right thing to do.
579 http://rt.cpan.org/Ticket/Display.html?id=29944
581 - re-worked most of the area filling code to use a common set of
582 functions when filling.
583 Corrected normal combine mode.
584 Rewrote most of the combine modes to match the way the SVG draft
585 defines them with respect to a translucent source and destination.
586 Added tests for translucent source and destination.
587 Added tests to check 8-bit/sample and double/sample combines work
589 https://rt.cpan.org/Ticket/Display.html?id=29879
591 - writing a 2 or 4 channel image to a JPEG file will now write that
592 image as if composited against a background, black by default,
593 overridable with the i_background tag/parameter.
594 https://rt.cpan.org/Ticket/Display.html?id=29876
596 - writing a 2 or 4 channel image to a PGM/PPM file will now write
597 that image as if composited against a background, black by default,
598 overridable with the i_background tag/parameter.
599 http://rt.cpan.org/Ticket/Display.html?id=30074
601 - writing a 2 or 4 channel image to a BMP file will now write that
602 image as if composited against a background, black by default,
603 overridable with the i_background tag/parameter.
604 http://rt.cpan.org/Ticket/Display.html?id=30075
608 - Imager::Matrix2d->translate() now only requires one of the x or y
610 http://rt.cpan.org/Ticket/Display.html?id=29937
612 - mixing qtype scaling now sets all channels of a pixel to zero if
613 the pixel has zero coverage (zero alpha). This should produce more
614 compressible output files.
615 http://rt.cpan.org/Ticket/Display.html?id=32324
617 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
619 https://bugzilla.redhat.com/show_bug.cgi?id=166254
620 I'm not changing the #! lines of the sample code, since it's sample
621 code, not intended for installation.
622 http://rt.cpan.org/Ticket/Display.html?id=33408
624 - some TGA images weren't being detected correctly as TGA images
625 https://rt.cpan.org/Ticket/Display.html?id=32925
627 - handling of the left-over bit for 16-bit/pixel TGA images has been
628 changed to match the behaviour of the GIMP. Previously the bit
629 being set was treated as an opaque pixel, but one user reported a
630 problem with loading such an image. I haven't been able to find any
631 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
632 I'll match it's behaviour. See issue 114913 in the GIMP's
634 http://rt.cpan.org/Ticket/Display.html?id=32926
636 Imager 0.62 - 10 December 2007
639 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
640 to /path under your home directory.
641 http://rt.cpan.org/Ticket/Display.html?id=29484
643 - the old dynaload code used Mach API functions to load dynamic
644 libraries on Mac OS X. These APIs have been deprecated in OS X
645 10.5 and were causing some build problems.
646 So henceforth Imager uses the dlopen() family of functions, and you
647 will need version 10.3 or later of OS X.
649 - added the det() function to the transform2() engine.
650 added the sample quad_to_square.pl
651 Courtesy Richard Fairhurst.
652 http://rt.cpan.org/Ticket/Display.html?id=31244
656 - samples/gifscale.pl sourced the base value for gif_top from
658 Thanks to Eleneldil G. Arilou for pointing this out.
660 - t/t82inline.t no longer loads B at runtime, to work around a bug
661 in some 5.005_0[45] installations.
662 http://rt.cpan.org/Ticket/Display.html?id=30508
664 - work around Module::Depends::Intrusive bug #21229
665 http://rt.cpan.org/Ticket/Display.html?id=30520
667 - the hardinvert filter no-longer inverts the alpha channel.
668 http://rt.cpan.org/Ticket/Display.html?id=30002
670 - the hardinvert filter now supports large samples
672 Imager 0.61_02 - 28 November 2007
675 - major TIFF support re-work
676 http://rt.cpan.org/Ticket/Display.html?id=20329
678 - added a C level image interface for accessing samples from 1-32
679 bits, exposed this at the perl level in getsamples()
681 - the conv filter now works at floating point precision for high bit
684 - added is_bilevel method to test whether an image should be written as
685 a bilevel image if the image format supports it.
687 - added -log-stderr as an Imager import list option
689 - added some important types to Imager::APIRef
691 - added test_image_double() to Imager::Test
695 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
698 - the scale() method with qtype mixing now handles images with an
699 alpha channel correctly.
701 - fixed a broken link from the "animated GIF" entry in the concept index.
702 Thanks to Slaven Rezic.
703 http://rt.cpan.org/Ticket/Display.html?id=30889
705 - on some perl's the infix expression parser test would fail due to
706 actions in the grammar returning false. Made sure all actions return
708 Thanks to Richard Fairhurst for spending a lot of time in tracking
710 http://rt.cpan.org/Public/Bug/Display.html?id=29562
712 Imager 0.61 - 5 November 2007
715 - added samples/gifscale.pl, which adjusts the screen size/position tags
716 when scaling an animated gif
717 http://rt.cpan.org/Ticket/Display.html?id=27591
721 - correct handling of sz in matrix_transform() - this should allow
722 perspective type transformations to work now.
723 http://rt.cpan.org/Ticket/Display.html?id=29936
725 - prevent a cast to integer warning on x64 builds in datatypes.c
726 also fixed some other type warnings
727 https://rt.cpan.org/Ticket/Display.html?id=30204
729 - some sub-directory tests depended on files produced by the parent
731 http://rt.cpan.org/Ticket/Display.html?id=30203
733 - Imager::Font::Wrap doesn't correctly set savepos
734 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
735 http://rt.cpan.org/Ticket/Display.html?id=29771
737 - test 171 in t/t01introvert.t was failing on perls configured to
739 http://rt.cpan.org/Ticket/Display.html?id=29413
741 - the code for the transform2() uminus operator was missing a break.
742 Added tests for better code coverage of the ops.
743 http://rt.cpan.org/Ticket/Display.html?id=29296
745 - the SGI RLE compression code could overflow its compression buffer
746 http://rt.cpan.org/Ticket/Display.html?id=30334
748 - the 32-bit output function used by the SGI code only handled values
749 under 0x10000. This was most noticable when writing large RLE images.
750 http://rt.cpan.org/Ticket/Display.html?id=30335
752 - validate chan_count for chans == NULL for each of the i_gsamp()
754 http://rt.cpan.org/Ticket/Display.html?id=28985
756 - attempt to work around the test failure at
757 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
758 http://rt.cpan.org/Ticket/Display.html?id=29562
760 - improve the error messages produced when attempting to read or write
761 an unknown image file format.
762 http://rt.cpan.org/Ticket/Display.html?id=30103
764 - improve the transform2() documentation
765 http://rt.cpan.org/Ticket/Display.html?id=29267
767 - correctly generate the author key in META.yml
768 http://rt.cpan.org/Ticket/Display.html?id=30377
770 - correctly blend a rotated (or matrix_transformed()) image when
771 performing interpolation in the presence of an alpha channel.
772 Also corrected the centring of the rotated image on the output
775 Imager 0.60 - 30 August 2007
778 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
779 now has full SGI RGB image format, including RLE and 16-bit/sample
781 https://rt.cpan.org/Ticket/Display.html?id=8666
783 - logging functions are now available in the API
785 - applied Gabriel Vasseur's patch
786 added documentation, further tests, and support for greyscale images
787 Obviously problems are my fault :)
788 https://rt.cpan.org/Ticket/Display.html?id=28142
790 - the mask for ICO/CUR images is now applied as an alpha channel to
791 the returned image. For the old behaviour, supply ico_masked => 0
792 to read() or read_multi(). This should be less confusing when
793 using Imager as a general image processor.
794 https://rt.cpan.org/Ticket/Display.html?id=29001
798 - in some cases it's possible for giflib/libungif to return color
799 indexes outside the range of colors defined by the image's palette.
800 We now expand the palette to match the indexes used.
801 Thanks to Gabriel Vasseur for reporting this.
803 - fixed various memory leaks that could occur when failing to read png,
804 jpeg, bmp or tga files.
806 - to avoid confusion, channels not present in the image are returned as
807 zero by getscanline(). This has no effect on the C level i_glin()
808 and i_glinf() API functions which continue to not set the unused
811 - the convert() method now returns an image of the same sample size as
813 https://rt.cpan.org/Ticket/Display.html?id=28492
815 - remove repeated text in Imager::Files
816 http://rt.cpan.org/Ticket/Display.html?id=27589
818 - be even more explicit that scale() and friends don't modify the source
819 image, but return a new image.
820 http://rt.cpan.org/Ticket/Display.html?id=28570
822 - improve the error message from errstr() when you try to load a font
823 for which the driver hasn't been built in Imager.
824 http://rt.cpan.org/Ticket/Display.html?id=27571
826 - transparency is now enabled by default when writing GIF images
827 http://rt.cpan.org/Ticket/Display.html?id=27615
829 - Imager would not load on Windows 98
830 http://rt.cpan.org/Ticket/Display.html?id=27653
832 Imager 0.59 - 14 June 2007
837 - fixes a regression introduced by the fixes for RT 11972
838 http://rt.cpan.org/Ticket/Display.html?id=27546
840 - cropping outside the image would return an Imager object with
841 no low-level image object, instead of returning false.
842 Fixed by: Philip Gwyn (Leolo)
843 http://rt.cpan.org/Ticket/Display.html?id=27509
845 Imager 0.58 - 16 May 2007
848 No significant changes from 0.57_01.
850 Imager 0.57_01 - 11 May 2007
853 - added to_rgb16 to produce a 16-bit/sample version of an image
855 - improve freetype 1.x text output efficiency
859 - search another place for rgb.txt, and check all the places
860 Imager::Color checks when deciding whether to skip testing it
861 http://rt.cpan.org/Ticket/Display.html?id=26064
863 - use a convolution kernel size based on the stddev rather than a
864 fixed size when performing a gaussian blur
865 http://rt.cpan.org/Ticket/Display.html?id=25645
867 - document the difference() method's mindist parameter, and debug it.
869 - put the Imager release number in the Inline::C generated code to
870 regenerate Inline code when a new release of Imager is installed.
871 http://rt.cpan.org/Ticket/Display.html?id=26278
873 - fix rendering on alpha channel images for the FreeType 1.x driver.
874 http://rt.cpan.org/Ticket/Display.html?id=11972
876 - fix rendering on alpha channel images for the T1lib driver.
877 http://rt.cpan.org/Ticket/Display.html?id=11972
879 - reworked library probing, we can now set more than one probe
880 function for a library. Disabled the default (non-freetype-config)
881 library probe and added an extra probe function that searches for
882 both ft2build.h and whatever it includes, and adds -I as needed.
883 Hopefully this will fix build problems like

885 http://rt.cpan.org/Ticket/Display.html?id=26086
887 Imager 0.57 - 30 Apr 2007
890 This is a maintenence release fixing a security issue in Imager.
892 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
893 overflow in malloced memory. There will be further discussion of
894 this issue in the ticket below.
895 http://rt.cpan.org/Ticket/Display.html?id=26811
896 CVE-2007-2459 CVE-2007-2413
897 The descriptions at cve.mitre.org varied in quality, please see the
898 ticket at rt.cpan.org for a more accurate description of the issue.
900 Imager 0.56 - 1 Apr 2007
903 - added support for reading 16-bit/sample PGM/PPM images
905 - added support for writing 16-bit/sample PGM/PPM images
907 - improved performance of reading PBM/PGM/PPM images
909 - added support for writing PBM images if the image is paletted and
910 contains only black and white
912 - added a new make_colors value - "mono"
914 - switched from the svn log Changes to a manual Changes to reduce
917 - new sample code - samples/flasher.pl
921 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
922 was returning an image object with an extra reference, this
923 resulted in a memory leak.
924 http://rt.cpan.org/Ticket/Display.html?id=24992
926 - fix rendering on alpha channel images for the FreeType 2.x driver
927 http://rt.cpan.org/Ticket/Display.html?id=11972
929 - reading bmp files now consitently handles short reads. You can now
930 supply a parameter to treat a short read as successful and set
932 http://rt.cpan.org/Ticket/Display.html?id=8426
934 - previously, reading ASCII PBM files required spaces between samples,
935 even though the format doesn't require that
937 - improved documentation of the unsharpmask filter (I hope)
938 http://rt.cpan.org/Ticket/Display.html?id=25531
940 - force flushing of the output from i_tt_dump_names() and test output
941 in t/t35ttfont.t to prevent output from being mixed up.
942 https://rt.cpan.org/Ticket/Display.html?id=24859
944 - rewrite a conditional expression as an if() to hopefully work around
945 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
946 https://rt.cpan.org/Ticket/Display.html?id=25561
948 - avoid Data::Dumper in regops.perl to support older releases of perl
949 https://rt.cpan.org/Ticket/Display.html?id=24391
951 Imager 0.55 - 16 Dec 2006
954 This is primarily a bug fix release.
956 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
958 There is one new feature:
960 - the Win32 font driver now supports UTF8 (RT 22166)
961 http://www.cpanforum.com/threads/3276
962 http://rt.cpan.org/Ticket/Display.html?id=22166
964 Several bugs were fixed:
966 - the string() method would not output the string "0"
967 http://rt.cpan.org/Public/Bug/Display.html?id=21770
969 - fills.c was failing to compile on Solaris 10 (compiler unknown)
970 http://rt.cpan.org/Public/Bug/Display.html?id=21944
972 - the gif_disposal and gif_user_input tags weren't being read from
974 http://rt.cpan.org/Public/Bug/Display.html?id=22192
976 - gif.c was failing to build under MSVC
977 http://rt.cpan.org/Ticket/Display.html?id=23922
979 - in some cases strings passed to the string() method were treated as
980 terminated by NUL (chr 0)
981 http://rt.cpan.org/Public/Bug/Display.html?id=21770
983 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
984 that's the default build name for zlib on Win32.
985 http://rt.cpan.org/Ticket/Display.html?id=23064
987 - search $Config{incpath} for headers too, which we should have been
990 Win32 font driver fixes:
992 - the global descent value from bounding box was the wrong sign
993 http://www.cpanforum.com/threads/3276
995 - if the first or last glyph overflowed the left or right side of the
996 advance width they would be clipped
999 Imager 0.54 - 14 Sep 2006
1002 This is primarily a feature release:
1004 - a new qtype value 'mixing' has been added to the scale()
1005 method. This is faster than 'normal', slower than 'preview'. This
1006 is based on the method used by pnmscale, and seems to produce less
1007 blurry results than normal.
1008 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1010 - the rubthrough() method can now render onto images with an alpha
1012 http://rt.cpan.org/Ticket/Display.html?id=20678
1014 - the read_multi() method now falls back to calling doing a single
1015 image read via the read() method and write_multi() will now fall
1016 back to calling write() if a single image is supplied. This means
1017 you can simply call the read_multi() or write_multi() functions
1018 without having to check if the type is formatted by that method.
1019 http://rt.cpan.org/Ticket/Display.html?id=19457
1020 http://rt.cpan.org/Ticket/Display.html?id=19458
1022 - the GIF loop extension can now be written. If you don't have
1023 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1025 http://rt.cpan.org/Ticket/Display.html?id=21185
1027 - getscanline() and setscanline() can now read/write palette index
1028 based data from/to the image for paletted images, by setting type to
1030 http://rt.cpan.org/Ticket/Display.html?id=20338
1032 - we no longer hassle you to disable GIF support
1033 http://rt.cpan.org/Ticket/Display.html?id=20687
1035 - minor documentation fixes
1038 Imager 0.53 - 26 Jul 2006
1041 This is a bugfix release.
1043 Some test code was left in a code path not covered by the test
1044 suite. A test was added to cover this code path and the test code was
1046 http://rt.cpan.org/Public/Bug/Display.html?id=20705
1049 Imager 0.52 - 25 Jul 2006
1052 This is primarily a feature release, but contains a fair few bug
1053 fixes, new features:
1055 - ability to read and write MS Windows ICO and CUR files
1057 - you can now add file format plugins to support new file formats
1059 - add POD coverage tests
1061 - setcolors() and addcolors() now accept color names and so on
1062 instead of requiring Imager::Color objects.
1063 http://rt.cpan.org/Ticket/Display.html?id=20056
1065 - flood_fill() can now fill to a specified border color instead of
1066 just to the area the same color as the seed.
1067 http://rt.cpan.org/Ticket/Display.html?id=19618
1072 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1073 calculating the advance width.
1074 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1076 - bounding_box for the T1 driver wasn't including leading and
1077 trailing spaces in the bounding box as the other drivers did, it also
1078 produced strange results for empty strings or strings containing only
1081 - when reading CMYK jpeg images they were being transferred to the
1082 image object as is, producing a four channel image. It only looked ok
1083 due to an old still unfixed Photoshop bug. We now convert from the
1084 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1085 http://rt.cpan.org/Ticket/Display.html?id=20416
1087 - reading a CYMK TIFF would result in a 4 channel image, reading any
1088 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1090 http://rt.cpan.org/Ticket/Display.html?id=20415
1092 - added /usr/local/include to the default include search path, since
1093 we were already searching /usr/local/lib for libraries.
1095 And various minor fixes and documentation updates.
1098 Imager 0.51 - 23 Apr 2006
1101 - fix a validation bug when processing JPEG EXIF data that can cause
1103 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1105 - fix mis-processing of the src_maxx and src_maxy parameters of the
1107 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1109 - fix a problem in Imager's "smart" handling of the color parameter
1111 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1114 Imager 0.50 - 29 Mar 2006
1117 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1118 or 4 channel image to jpeg or a 2 channel image to tga where the
1119 output is an in-memeory buffer.
1120 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1122 - fixes an incorrect pointer parameter in the PNG code
1123 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1125 - skip Inline::C tests when building in a directory with spaces
1126 http://rt.cpan.org/Public/Bug/Display.html?id=18049
