1 Imager release history. Older releases can be found in Changes.old
3 Imager 0.79 - unreleased
6 - add Imager::Test to the POD coverage tests and document the missing
9 - the convert() method now optimizes the case where all output
10 channels are either 0, sourced from a single input channel or 1.
11 This significantly speeds up presets like "addalpha", "green".
12 https://rt.cpan.org/Ticket/Display.html?id=51254
14 - add wiggle.pl sample, as suggested by Dan Oppenheim.
18 - treat the co-efficients for convert() as doubles instead of floats.
20 Imager 0.78 - 4 Oct 2010
25 - don't access deprecated members of the png_structp.
26 https://rt.cpan.org/Ticket/Display.html?id=60242

44 https://rt.cpan.org/Ticket/Display.html?id=60221
48 - from _01: look for missing file support test files in the right
51 - flood_fill() wouldn't fill the right side of a single scan-line
53 Thanks to Nicolas Roggli for reporting this.
55 - flood_fill wouldn't fill to the left edge of the image if the
56 starting line didn't reach the left edge.
57 Thanks to Nicolas Roggli for reporting this.
59 Imager 0.77_01 - 13 Sep 2010
62 - add each library-directory/pkgconfig/ to the pkg-config search path
64 Thanks to Justin Davis.
65 https://rt.cpan.org/Ticket/Display.html?id=60491
67 - moved GIF, TIFF, JPEG file handling code into sub-modules in
68 preparation for separate distribution.
69 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
71 - optimize filled box drawing (color, not fill)
75 - Imager::Probe was calling ExtUtils::Liblist to initialize
76 LD_RUN_PATH supplying an undefined value rather than the found
77 directory. Thanks to Justin Davis.
78 https://rt.cpan.org/Ticket/Display.html?id=60491
80 - only prepend ./ to font filenames when passing them to T1Lib and
81 then only when it would use its search mechanisms.
82 https://rt.cpan.org/Ticket/Display.html?id=60509
84 - fix the cache check for the X rgb.txt loader. This is typically
85 used for color translation on Unix-like systems, and the fix
86 improves performance of supplying colors by name by about 80 times.
87 Test code that managed 3400 10x10 pixel boxes/second sped up to
90 - clarify that Imager doesn't write EXIF metadata to images.
91 https://rt.cpan.org/Ticket/Display.html?id=60637
93 - Imager::Probe can now search subdirectories under its include path.
94 Used by the PNG Makefile.PL to find headers and libraries when they
95 aren't in the base directory, as in cygwin.
96 https://rt.cpan.org/Ticket/Display.html?id=60635
98 Imager 0.77 - 11 Aug 2010
101 I don't want Imager::File::PNG indexed as part of Imager, but forgot
102 to update the META.yml before updating the version.
104 - don't index Imager::File::PNG as part of Imager
106 - add resources to META.yml
108 Imager 0.76 - not released
113 - the align_string() method would ignore a string of "0" due to a
115 Thanks to Maurice Height for reporting this.
116 https://rt.cpan.org/Ticket/Display.html?id=60199
118 Imager 0.75_03 - 09 Aug 2010
123 - read_types() and write_types() would include png when it wasn't
124 available due to a problem with the %formats tie
126 - handle dependent libraries correctly (eg -lpng requiring -lz) in
127 the code run phase of library probing.
129 Imager 0.75_02 - 07 Aug 2010
134 - add file missing from MANIFEST, which was causing TIFF failures.
136 Imager 0.75_01 - 06 Aug 2010
139 Test release for the new PNG probe.
141 - added the ability to read multiple-image PNM files.
142 Note that unlike the pbm/pgm/ppm specification this accepts mixed
143 format files and allows white space padding between files.
144 Thanks to Philip Gwyn (Leolo) for this patch.
146 - moved the PNG file handling code into a sub-module in preparation
147 for separate distribution.
148 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
149 Also helps avoid complications from -I/-L compile/link options from
154 - Imager->new(data => $data) didn't try to process image file data in
156 https://rt.cpan.org/Ticket/Display.html?id=58761
158 - t/t50basicoo.t no longer depends on the other tests to generate its
160 https://rt.cpan.org/Ticket/Display.html?id=9798
161 Also, it wasn't testing pnm (pnm vs ppm mix-up)
163 - update the documentation of hardinvert to match the change in 0.62.
164 https://rt.cpan.org/Ticket/Display.html?id=59785
166 - added hardinvertall filter which also inverts the alpha channel
169 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
170 the probe can find the library for the test run.
171 https://rt.cpan.org/Ticket/Display.html?id=57518
173 Imager 0.75 - 20 Jun 2010
176 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
181 - an opacity fill based on a fountain fill would segfault when
182 filling an 8-bit/sample image.
184 - merge thickline branch polygon fix
185 https://rt.cpan.org/Ticket/Display.html?id=43518
187 Imager 0.74 - 7 May 2010
192 - read_multi() didn't handle a missing file format library correctly,
193 aborting on failing to call i_readgif_multi_wiol() or
194 i_readtiff_multi_wiol().
196 - fix spelling errors patched by Debian
197 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
199 - add an (unshipped) author test to spellcheck Imager's POD.
201 - update the TIFF file format documentation
202 https://rt.cpan.org/Ticket/Display.html?id=56510
204 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
206 Imager 0.73 - 15 Mar 2010
209 - implement outline circles, both anti-aliased and not
210 https://rt.cpan.org/Ticket/Display.html?id=19755
212 - a combine => "none" fill to a 1 or 3 channel image would produce
213 the incorrect colour.
215 Imager 0.72 - 09 Dec 2009
218 Bump version for release, since 0.71_03 is stable with CPAN testers.
220 Imager 0.71_03 - 5 Dec 2009
223 - further adjust the threads test so it only performs the tests on
224 perls where it's expected to work, and only if the threads module
227 Imager 0.71_02 - 1 Dec 2009
230 - adjust the way we load the threads module for the threads test so
231 it works with non-threaded perls
233 Imager 0.71_01 - 30 Nov 2009
238 - use scanline oriented operations to flip images instead of pixel
240 https://rt.cpan.org/Ticket/Display.html?id=39278
242 - use double/sample operations to flip large sample images instead of
243 8-bit sample operations.
244 https://rt.cpan.org/Ticket/Display.html?id=39280
247 https://rt.cpan.org/Ticket/Display.html?id=51874
249 - prevent double-frees when someone creates Imager objects and then
250 creates a thread. Note: this just handles some simple cases,
251 Imager doesn't support perl threads, and isn't likely to.
252 https://rt.cpan.org/Ticket/Display.html?id=52268
254 Imager 0.71 - 16 Nov 2009
257 - add the opacity fill type - an adaptor that modifies the opacity of
262 - the conv filter now enforces that the sum of the coefficients is
263 non-zero. Also, rather than skipping pixels off the edge off the
264 edge of the image, the closest edge pixel is used. Previously
265 dividing by the zero sum of coefficients could cause invalid
266 results or runtime exceptions.
267 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
270 Imager 0.70 - 21 Sep 2009
275 - release image row and comments memory on all error returns in gif
278 - handle zero length extensions, previously this would cause a null
280 Thanks to Krzysztof WojtaÅ for the test data and fix for this.
282 - an integer division meant that preview scaling to below 1 pixel
283 wide or high (which isn't too useful anyway) was calculating using
284 NaNs on most platforms, and causing an exception on others.
285 Thanks to David Cantrell for producing a backtrace of the crash on
286 his Alpha-NetBSD CPAN test box which made it possible to track this
289 Imager 0.69 - 08 Sep 2009
294 - broken test fix - was attempting to call a function skip_all, when
295 that should be a parameter to plan().
297 - briefly document apidocs.perl, the tool used to build
298 Imager::APIRef and make some minor enhancements
300 - various minor documentation enhancements and fixes.
302 Imager 0.68 - 07 Sep 2009
305 - Imager->new(file => $filename) and other similar incantations will
307 https://rt.cpan.org/Ticket/Display.html?id=48261
311 - avoid using CHECK as a label in Imager::Test
312 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
314 - re-work most image file test files that require a library into
315 separate library present/not present files to remove stupidly long
318 - don't treat rubthrough() outside the bounds of the target image as
320 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
322 Imager 0.67_01 - 02 Sep 2009
327 - correct documentation of default of raw image interleave read
329 https://rt.cpan.org/Ticket/Display.html?id=42074
331 - add raw_ prefix to raw read parameters, though the original names
334 - fail the read if an invalid raw_interleave parameter is supplied
336 - warn if no interleave or raw_interleave parameter is supplied,
337 since the documented default was wrong, and incompatible with the
340 - for reading raw images, if raw_storechannels > raw_datachannels,
341 set the extra channels in the image to 0
343 - when probing for executables like freetype-config, search for .bat
344 and .cmd on MSWin32, as well as .exe.
345 https://rt.cpan.org/Ticket/Display.html?id=49275
347 - re-work the external libraries section of README:
348 - list Debian and Redhat package names for each library
352 - use the new EU::MM META_MERGE facility instead of generating
353 META.yml from scratch
354 https://rt.cpan.org/Ticket/Display.html?id=47888
356 - use Devel::CheckLib (bundled, modified) to check which release of
357 libtiff is installed and reject 3.9.0
358 http://bugzilla.maptools.org/show_bug.cgi?id=2088
359 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
361 Imager 0.67 - 12 Dec 2008
366 - fix a packaging error
368 Imager 0.66 - 12 Dec 2008
371 - 24-bit color .ICO/.CUR files can now be read.
375 - an optimization skipping 0 src alpha values could cause the
376 rubthrough() to read past the end of a buffer.
377 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
379 - corrected a reference leak where writing GIFs would leak memory.
380 This could also happen calling to_paletted().
381 Also documented the underlying long existing feature where the
382 colors parameter is filled with the generated color table and added
384 http://rt.cpan.org/Ticket/Display.html?id=41028
386 - write out the image size in bytes field of a BMP correctly.
387 http://rt.cpan.org/Ticket/Display.html?id=41406
389 - add limited tests for Imager::ExtUtils
391 - make Imager::ExtUtils->includes use an absolute path, since
392 a relative path could cause failures using Inline::C.
393 http://rt.cpan.org/Ticket/Display.html?id=37353
395 - re-arrange the POD for Imager::Font::BBox:
396 - mark total_width(), pos_width(), end_offset() obsolete, since
397 they're mostly for backwards compatibility
398 - group width methods and height methods
399 https://rt.cpan.org/Ticket/Display.html?id=39999
401 Imager 0.65 - 20 May 2008
406 - In some cases when an error occurs reading those parts of a JPEG
407 file after the image the scan-line buffer could be freed a second
408 time. In cases where the the error occured while reading the image
409 data it's possible that the buffer could have leaked.
410 Thanks to Gabriel Vasseur for reporting this and help in tracking
413 - the gif_screen_height tag was overriding the screen width and being
414 ignored for the screen height when present.
415 https://rt.cpan.org/Public/Bug/Display.html?id=35568
417 Imager 0.64 - 23 April 2008
420 This is a bug fix release. This includes a fix for a possible
425 - Possible security issue: The floating point sample path for image
426 based fills had a buffer overflow. This would overwrite the end of
427 a malloc()ed buffer with double precision floats.
428 http://rt.cpan.org/Ticket/Display.html?id=35324
431 - check that the result of fileno($fh) is defined rather than simply
432 true when read() or write() is supplied with an fh parameter.
433 http://rt.cpan.org/Ticket/Display.html?id=35139
435 - i_scale_axis() wasn't checking the result of i_img_new_ch()
436 resulting in a SIGSEGV when attempting to scale an image to a size
437 too large to fit in memory. This is a NULL pointer access issue,
438 not a buffer overflow.
439 Added a check for the failure.
440 scale_calculate() (and hence scale()) will now fail if any of the
441 scale size parameters are a reference.
442 http://rt.cpan.org/Ticket/Display.html?id=35172
444 - Regression: filling a greyscale image with a hatch used the wrong
445 color channels from the supplied fg/bg colors.
446 https://rt.cpan.org/Ticket/Display.html?id=35278
448 - fixed a related problem for image fills.
450 Imager 0.63 - 7 April 2008
453 This release primarily contains changes to improve ease of use -
454 rather than you having to convert images to the appropriate number of
455 channels, Imager handles it internally. How to handle drawing colors
456 and the default combine mode is a thornier problem left for some other
459 - the font libraries are now only initialized when needed.
460 http://rt.cpan.org/Ticket/Display.html?id=28825
462 - moved the imtoc.perl code into Imager::Preprocess
464 - paste() and rubthrough() now adapt the source image data to the
465 destination, so you can now safely paste/rubthrough from greyscale
466 images to color images or back, or from alpha channel images to
467 noalpha channels or back.
468 https://rt.cpan.org/Ticket/Display.html?id=30908
470 - rubthrough() now falls back to pasting when the source doesn't have
471 an alpha channel. This effectively treats the source as having a
472 max alpha channel, the right thing to do.
473 http://rt.cpan.org/Ticket/Display.html?id=29944
475 - re-worked most of the area filling code to use a common set of
476 functions when filling.
477 Corrected normal combine mode.
478 Rewrote most of the combine modes to match the way the SVG draft
479 defines them with respect to a translucent source and destination.
480 Added tests for translucent source and destination.
481 Added tests to check 8-bit/sample and double/sample combines work
483 https://rt.cpan.org/Ticket/Display.html?id=29879
485 - writing a 2 or 4 channel image to a JPEG file will now write that
486 image as if composited against a background, black by default,
487 overridable with the i_background tag/parameter.
488 https://rt.cpan.org/Ticket/Display.html?id=29876
490 - writing a 2 or 4 channel image to a PGM/PPM file will now write
491 that image as if composited against a background, black by default,
492 overridable with the i_background tag/parameter.
493 http://rt.cpan.org/Ticket/Display.html?id=30074
495 - writing a 2 or 4 channel image to a BMP file will now write that
496 image as if composited against a background, black by default,
497 overridable with the i_background tag/parameter.
498 http://rt.cpan.org/Ticket/Display.html?id=30075
502 - Imager::Matrix2d->translate() now only requires one of the x or y
504 http://rt.cpan.org/Ticket/Display.html?id=29937
506 - mixing qtype scaling now sets all channels of a pixel to zero if
507 the pixel has zero coverage (zero alpha). This should produce more
508 compressible output files.
509 http://rt.cpan.org/Ticket/Display.html?id=32324
511 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
513 https://bugzilla.redhat.com/show_bug.cgi?id=166254
514 I'm not changing the #! lines of the sample code, since it's sample
515 code, not intended for installation.
516 http://rt.cpan.org/Ticket/Display.html?id=33408
518 - some TGA images weren't being detected correctly as TGA images
519 https://rt.cpan.org/Ticket/Display.html?id=32925
521 - handling of the left-over bit for 16-bit/pixel TGA images has been
522 changed to match the behaviour of the GIMP. Previously the bit
523 being set was treated as an opaque pixel, but one user reported a
524 problem with loading such an image. I haven't been able to find any
525 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
526 I'll match it's behaviour. See issue 114913 in the GIMP's
528 http://rt.cpan.org/Ticket/Display.html?id=32926
530 Imager 0.62 - 10 December 2007
533 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
534 to /path under your home directory.
535 http://rt.cpan.org/Ticket/Display.html?id=29484
537 - the old dynaload code used Mach API functions to load dynamic
538 libraries on Mac OS X. These APIs have been deprecated in OS X
539 10.5 and were causing some build problems.
540 So henceforth Imager uses the dlopen() family of functions, and you
541 will need version 10.3 or later of OS X.
543 - added the det() function to the transform2() engine.
544 added the sample quad_to_square.pl
545 Courtesy Richard Fairhurst.
546 http://rt.cpan.org/Ticket/Display.html?id=31244
550 - samples/gifscale.pl sourced the base value for gif_top from
552 Thanks to Eleneldil G. Arilou for pointing this out.
554 - t/t82inline.t no longer loads B at runtime, to work around a bug
555 in some 5.005_0[45] installations.
556 http://rt.cpan.org/Ticket/Display.html?id=30508
558 - work around Module::Depends::Intrusive bug #21229
559 http://rt.cpan.org/Ticket/Display.html?id=30520
561 - the hardinvert filter no-longer inverts the alpha channel.
562 http://rt.cpan.org/Ticket/Display.html?id=30002
564 - the hardinvert filter now supports large samples
566 Imager 0.61_02 - 28 November 2007
569 - major TIFF support re-work
570 http://rt.cpan.org/Ticket/Display.html?id=20329
572 - added a C level image interface for accessing samples from 1-32
573 bits, exposed this at the perl level in getsamples()
575 - the conv filter now works at floating point precision for high bit
578 - added is_bilevel method to test whether an image should be written as
579 a bilevel image if the image format supports it.
581 - added -log-stderr as an Imager import list option
583 - added some important types to Imager::APIRef
585 - added test_image_double() to Imager::Test
589 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
592 - the scale() method with qtype mixing now handles images with an
593 alpha channel correctly.
595 - fixed a broken link from the "animated GIF" entry in the concept index.
596 Thanks to Slaven Rezic.
597 http://rt.cpan.org/Ticket/Display.html?id=30889
599 - on some perl's the infix expression parser test would fail due to
600 actions in the grammar returning false. Made sure all actions return
602 Thanks to Richard Fairhurst for spending a lot of time in tracking
604 http://rt.cpan.org/Public/Bug/Display.html?id=29562
606 Imager 0.61 - 5 November 2007
609 - added samples/gifscale.pl, which adjusts the screen size/position tags
610 when scaling an animated gif
611 http://rt.cpan.org/Ticket/Display.html?id=27591
615 - correct handling of sz in matrix_transform() - this should allow
616 perspective type transformations to work now.
617 http://rt.cpan.org/Ticket/Display.html?id=29936
619 - prevent a cast to integer warning on x64 builds in datatypes.c
620 also fixed some other type warnings
621 https://rt.cpan.org/Ticket/Display.html?id=30204
623 - some sub-directory tests depended on files produced by the parent
625 http://rt.cpan.org/Ticket/Display.html?id=30203
627 - Imager::Font::Wrap doesn't correctly set savepos
628 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
629 http://rt.cpan.org/Ticket/Display.html?id=29771
631 - test 171 in t/t01introvert.t was failing on perls configured to
633 http://rt.cpan.org/Ticket/Display.html?id=29413
635 - the code for the transform2() uminus operator was missing a break.
636 Added tests for better code coverage of the ops.
637 http://rt.cpan.org/Ticket/Display.html?id=29296
639 - the SGI RLE compression code could overflow its compression buffer
640 http://rt.cpan.org/Ticket/Display.html?id=30334
642 - the 32-bit output function used by the SGI code only handled values
643 under 0x10000. This was most noticable when writing large RLE images.
644 http://rt.cpan.org/Ticket/Display.html?id=30335
646 - validate chan_count for chans == NULL for each of the i_gsamp()
648 http://rt.cpan.org/Ticket/Display.html?id=28985
650 - attempt to work around the test failure at
651 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
652 http://rt.cpan.org/Ticket/Display.html?id=29562
654 - improve the error messages produced when attempting to read or write
655 an unknown image file format.
656 http://rt.cpan.org/Ticket/Display.html?id=30103
658 - improve the transform2() documentation
659 http://rt.cpan.org/Ticket/Display.html?id=29267
661 - correctly generate the author key in META.yml
662 http://rt.cpan.org/Ticket/Display.html?id=30377
664 - correctly blend a rotated (or matrix_transformed()) image when
665 performing interpolation in the presence of an alpha channel.
666 Also corrected the centring of the rotated image on the output
669 Imager 0.60 - 30 August 2007
672 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
673 now has full SGI RGB image format, including RLE and 16-bit/sample
675 https://rt.cpan.org/Ticket/Display.html?id=8666
677 - logging functions are now available in the API
679 - applied Gabriel Vasseur's patch
680 added documentation, further tests, and support for greyscale images
681 Obviously problems are my fault :)
682 https://rt.cpan.org/Ticket/Display.html?id=28142
684 - the mask for ICO/CUR images is now applied as an alpha channel to
685 the returned image. For the old behaviour, supply ico_masked => 0
686 to read() or read_multi(). This should be less confusing when
687 using Imager as a general image processor.
688 https://rt.cpan.org/Ticket/Display.html?id=29001
692 - in some cases it's possible for giflib/libungif to return color
693 indexes outside the range of colors defined by the image's palette.
694 We now expand the palette to match the indexes used.
695 Thanks to Gabriel Vasseur for reporting this.
697 - fixed various memory leaks that could occur when failing to read png,
698 jpeg, bmp or tga files.
700 - to avoid confusion, channels not present in the image are returned as
701 zero by getscanline(). This has no effect on the C level i_glin()
702 and i_glinf() API functions which continue to not set the unused
705 - the convert() method now returns an image of the same sample size as
707 https://rt.cpan.org/Ticket/Display.html?id=28492
709 - remove repeated text in Imager::Files
710 http://rt.cpan.org/Ticket/Display.html?id=27589
712 - be even more explicit that scale() and friends don't modify the source
713 image, but return a new image.
714 http://rt.cpan.org/Ticket/Display.html?id=28570
716 - improve the error message from errstr() when you try to load a font
717 for which the driver hasn't been built in Imager.
718 http://rt.cpan.org/Ticket/Display.html?id=27571
720 - transparency is now enabled by default when writing GIF images
721 http://rt.cpan.org/Ticket/Display.html?id=27615
723 - Imager would not load on Windows 98
724 http://rt.cpan.org/Ticket/Display.html?id=27653
726 Imager 0.59 - 14 June 2007
731 - fixes a regression introduced by the fixes for RT 11972
732 http://rt.cpan.org/Ticket/Display.html?id=27546
734 - cropping outside the image would return an Imager object with
735 no low-level image object, instead of returning false.
736 Fixed by: Philip Gwyn (Leolo)
737 http://rt.cpan.org/Ticket/Display.html?id=27509
739 Imager 0.58 - 16 May 2007
742 No significant changes from 0.57_01.
744 Imager 0.57_01 - 11 May 2007
747 - added to_rgb16 to produce a 16-bit/sample version of an image
749 - improve freetype 1.x text output efficiency
753 - search another place for rgb.txt, and check all the places
754 Imager::Color checks when deciding whether to skip testing it
755 http://rt.cpan.org/Ticket/Display.html?id=26064
757 - use a convolution kernel size based on the stddev rather than a
758 fixed size when performing a gaussian blur
759 http://rt.cpan.org/Ticket/Display.html?id=25645
761 - document the difference() method's mindist parameter, and debug it.
763 - put the Imager release number in the Inline::C generated code to
764 regenerate Inline code when a new release of Imager is installed.
765 http://rt.cpan.org/Ticket/Display.html?id=26278
767 - fix rendering on alpha channel images for the FreeType 1.x driver.
768 http://rt.cpan.org/Ticket/Display.html?id=11972
770 - fix rendering on alpha channel images for the T1lib driver.
771 http://rt.cpan.org/Ticket/Display.html?id=11972
773 - reworked library probing, we can now set more than one probe
774 function for a library. Disabled the default (non-freetype-config)
775 library probe and added an extra probe function that searches for
776 both ft2build.h and whatever it includes, and adds -I as needed.
777 Hopefully this will fix build problems like

779 http://rt.cpan.org/Ticket/Display.html?id=26086
781 Imager 0.57 - 30 Apr 2007
784 This is a maintenence release fixing a security issue in Imager.
786 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
787 overflow in malloced memory. There will be further discussion of
788 this issue in the ticket below.
789 http://rt.cpan.org/Ticket/Display.html?id=26811
790 CVE-2007-2459 CVE-2007-2413
791 The descriptions at cve.mitre.org varied in quality, please see the
792 ticket at rt.cpan.org for a more accurate description of the issue.
794 Imager 0.56 - 1 Apr 2007
797 - added support for reading 16-bit/sample PGM/PPM images
799 - added support for writing 16-bit/sample PGM/PPM images
801 - improved performance of reading PBM/PGM/PPM images
803 - added support for writing PBM images if the image is paletted and
804 contains only black and white
806 - added a new make_colors value - "mono"
808 - switched from the svn log Changes to a manual Changes to reduce
811 - new sample code - samples/flasher.pl
815 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
816 was returning an image object with an extra reference, this
817 resulted in a memory leak.
818 http://rt.cpan.org/Ticket/Display.html?id=24992
820 - fix rendering on alpha channel images for the FreeType 2.x driver
821 http://rt.cpan.org/Ticket/Display.html?id=11972
823 - reading bmp files now consitently handles short reads. You can now
824 supply a parameter to treat a short read as successful and set
826 http://rt.cpan.org/Ticket/Display.html?id=8426
828 - previously, reading ASCII PBM files required spaces between samples,
829 even though the format doesn't require that
831 - improved documentation of the unsharpmask filter (I hope)
832 http://rt.cpan.org/Ticket/Display.html?id=25531
834 - force flushing of the output from i_tt_dump_names() and test output
835 in t/t35ttfont.t to prevent output from being mixed up.
836 https://rt.cpan.org/Ticket/Display.html?id=24859
838 - rewrite a conditional expression as an if() to hopefully work around
839 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
840 https://rt.cpan.org/Ticket/Display.html?id=25561
842 - avoid Data::Dumper in regops.perl to support older releases of perl
843 https://rt.cpan.org/Ticket/Display.html?id=24391
845 Imager 0.55 - 16 Dec 2006
848 This is primarily a bug fix release.
850 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
852 There is one new feature:
854 - the Win32 font driver now supports UTF8 (RT 22166)
855 http://www.cpanforum.com/threads/3276
856 http://rt.cpan.org/Ticket/Display.html?id=22166
858 Several bugs were fixed:
860 - the string() method would not output the string "0"
861 http://rt.cpan.org/Public/Bug/Display.html?id=21770
863 - fills.c was failing to compile on Solaris 10 (compiler unknown)
864 http://rt.cpan.org/Public/Bug/Display.html?id=21944
866 - the gif_disposal and gif_user_input tags weren't being read from
868 http://rt.cpan.org/Public/Bug/Display.html?id=22192
870 - gif.c was failing to build under MSVC
871 http://rt.cpan.org/Ticket/Display.html?id=23922
873 - in some cases strings passed to the string() method were treated as
874 terminated by NUL (chr 0)
875 http://rt.cpan.org/Public/Bug/Display.html?id=21770
877 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
878 that's the default build name for zlib on Win32.
879 http://rt.cpan.org/Ticket/Display.html?id=23064
881 - search $Config{incpath} for headers too, which we should have been
884 Win32 font driver fixes:
886 - the global descent value from bounding box was the wrong sign
887 http://www.cpanforum.com/threads/3276
889 - if the first or last glyph overflowed the left or right side of the
890 advance width they would be clipped
893 Imager 0.54 - 14 Sep 2006
896 This is primarily a feature release:
898 - a new qtype value 'mixing' has been added to the scale()
899 method. This is faster than 'normal', slower than 'preview'. This
900 is based on the method used by pnmscale, and seems to produce less
901 blurry results than normal.
902 http://rt.cpan.org/Public/Bug/Display.html?id=20677
904 - the rubthrough() method can now render onto images with an alpha
906 http://rt.cpan.org/Ticket/Display.html?id=20678
908 - the read_multi() method now falls back to calling doing a single
909 image read via the read() method and write_multi() will now fall
910 back to calling write() if a single image is supplied. This means
911 you can simply call the read_multi() or write_multi() functions
912 without having to check if the type is formatted by that method.
913 http://rt.cpan.org/Ticket/Display.html?id=19457
914 http://rt.cpan.org/Ticket/Display.html?id=19458
916 - the GIF loop extension can now be written. If you don't have
917 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
919 http://rt.cpan.org/Ticket/Display.html?id=21185
921 - getscanline() and setscanline() can now read/write palette index
922 based data from/to the image for paletted images, by setting type to
924 http://rt.cpan.org/Ticket/Display.html?id=20338
926 - we no longer hassle you to disable GIF support
927 http://rt.cpan.org/Ticket/Display.html?id=20687
929 - minor documentation fixes
932 Imager 0.53 - 26 Jul 2006
935 This is a bugfix release.
937 Some test code was left in a code path not covered by the test
938 suite. A test was added to cover this code path and the test code was
940 http://rt.cpan.org/Public/Bug/Display.html?id=20705
943 Imager 0.52 - 25 Jul 2006
946 This is primarily a feature release, but contains a fair few bug
949 - ability to read and write MS Windows ICO and CUR files
951 - you can now add file format plugins to support new file formats
953 - add POD coverage tests
955 - setcolors() and addcolors() now accept color names and so on
956 instead of requiring Imager::Color objects.
957 http://rt.cpan.org/Ticket/Display.html?id=20056
959 - flood_fill() can now fill to a specified border color instead of
960 just to the area the same color as the seed.
961 http://rt.cpan.org/Ticket/Display.html?id=19618
966 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
967 calculating the advance width.
968 http://rt.cpan.org/Public/Bug/Display.html?id=20554
970 - bounding_box for the T1 driver wasn't including leading and
971 trailing spaces in the bounding box as the other drivers did, it also
972 produced strange results for empty strings or strings containing only
975 - when reading CMYK jpeg images they were being transferred to the
976 image object as is, producing a four channel image. It only looked ok
977 due to an old still unfixed Photoshop bug. We now convert from the
978 inverted CMYK that photoshop (and Corel for example) produce into RGB.
979 http://rt.cpan.org/Ticket/Display.html?id=20416
981 - reading a CYMK TIFF would result in a 4 channel image, reading any
982 image with more than 4 channels (eg. RGB with 2 alpha channels) would
984 http://rt.cpan.org/Ticket/Display.html?id=20415
986 - added /usr/local/include to the default include search path, since
987 we were already searching /usr/local/lib for libraries.
989 And various minor fixes and documentation updates.
992 Imager 0.51 - 23 Apr 2006
995 - fix a validation bug when processing JPEG EXIF data that can cause
997 http://rt.cpan.org/Public/Bug/Display.html?id=18496
999 - fix mis-processing of the src_maxx and src_maxy parameters of the
1001 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1003 - fix a problem in Imager's "smart" handling of the color parameter
1005 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1008 Imager 0.50 - 29 Mar 2006
1011 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1012 or 4 channel image to jpeg or a 2 channel image to tga where the
1013 output is an in-memeory buffer.
1014 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1016 - fixes an incorrect pointer parameter in the PNG code
1017 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1019 - skip Inline::C tests when building in a directory with spaces
1020 http://rt.cpan.org/Public/Bug/Display.html?id=18049
