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.
16 - add the combine() method to combine channels from multiple source
17 images into a new image
18 https://rt.cpan.org/Ticket/Display.html?id=11872
22 - treat the co-efficients for convert() as doubles instead of floats.
24 - If a higher (earlier) priority font handler failed to load, that
25 would crash preventing loading of later font handlers.
26 https://rt.cpan.org/Ticket/Display.html?id=62855
28 - parse defines from the options returned by pkg-config --cflags
29 https://rt.cpan.org/Ticket/Display.html?id=63223
31 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
32 included in the tarball. They are now included.
34 Imager 0.78 - 4 Oct 2010
39 - don't access deprecated members of the png_structp.
40 https://rt.cpan.org/Ticket/Display.html?id=60242

47 https://rt.cpan.org/Ticket/Display.html?id=60244
49 Imager 0.77_02 - 27 Sep 2010
52 - moved Win32, FreeType 2 font support into sub-modules.
53 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
54 Uses Imager::Probe now.
55 https://rt.cpan.org/Public/Bug/Display.html?id=61328
57 - tested successfully with jpeg-8b
58 https://rt.cpan.org/Ticket/Display.html?id=60221
62 - from _01: look for missing file support test files in the right
65 - flood_fill() wouldn't fill the right side of a single scan-line
67 Thanks to Nicolas Roggli for reporting this.
69 - flood_fill wouldn't fill to the left edge of the image if the
70 starting line didn't reach the left edge.
71 Thanks to Nicolas Roggli for reporting this.
73 Imager 0.77_01 - 13 Sep 2010
76 - add each library-directory/pkgconfig/ to the pkg-config search path
78 Thanks to Justin Davis.
79 https://rt.cpan.org/Ticket/Display.html?id=60491
81 - moved GIF, TIFF, JPEG file handling code into sub-modules in
82 preparation for separate distribution.
83 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
85 - optimize filled box drawing (color, not fill)
89 - Imager::Probe was calling ExtUtils::Liblist to initialize
90 LD_RUN_PATH supplying an undefined value rather than the found
91 directory. Thanks to Justin Davis.
92 https://rt.cpan.org/Ticket/Display.html?id=60491
94 - only prepend ./ to font filenames when passing them to T1Lib and
95 then only when it would use its search mechanisms.
96 https://rt.cpan.org/Ticket/Display.html?id=60509
98 - fix the cache check for the X rgb.txt loader. This is typically
99 used for color translation on Unix-like systems, and the fix
100 improves performance of supplying colors by name by about 80 times.
101 Test code that managed 3400 10x10 pixel boxes/second sped up to
104 - clarify that Imager doesn't write EXIF metadata to images.
105 https://rt.cpan.org/Ticket/Display.html?id=60637
107 - Imager::Probe can now search subdirectories under its include path.
108 Used by the PNG Makefile.PL to find headers and libraries when they
109 aren't in the base directory, as in cygwin.
110 https://rt.cpan.org/Ticket/Display.html?id=60635
112 Imager 0.77 - 11 Aug 2010
115 I don't want Imager::File::PNG indexed as part of Imager, but forgot
116 to update the META.yml before updating the version.
118 - don't index Imager::File::PNG as part of Imager
120 - add resources to META.yml
122 Imager 0.76 - not released
127 - the align_string() method would ignore a string of "0" due to a
129 Thanks to Maurice Height for reporting this.
130 https://rt.cpan.org/Ticket/Display.html?id=60199
132 Imager 0.75_03 - 09 Aug 2010
137 - read_types() and write_types() would include png when it wasn't
138 available due to a problem with the %formats tie
140 - handle dependent libraries correctly (eg -lpng requiring -lz) in
141 the code run phase of library probing.
143 Imager 0.75_02 - 07 Aug 2010
148 - add file missing from MANIFEST, which was causing TIFF failures.
150 Imager 0.75_01 - 06 Aug 2010
153 Test release for the new PNG probe.
155 - added the ability to read multiple-image PNM files.
156 Note that unlike the pbm/pgm/ppm specification this accepts mixed
157 format files and allows white space padding between files.
158 Thanks to Philip Gwyn (Leolo) for this patch.
160 - moved the PNG file handling code into a sub-module in preparation
161 for separate distribution.
162 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
163 Also helps avoid complications from -I/-L compile/link options from
168 - Imager->new(data => $data) didn't try to process image file data in
170 https://rt.cpan.org/Ticket/Display.html?id=58761
172 - t/t50basicoo.t no longer depends on the other tests to generate its
174 https://rt.cpan.org/Ticket/Display.html?id=9798
175 Also, it wasn't testing pnm (pnm vs ppm mix-up)
177 - update the documentation of hardinvert to match the change in 0.62.
178 https://rt.cpan.org/Ticket/Display.html?id=59785
180 - added hardinvertall filter which also inverts the alpha channel
183 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
184 the probe can find the library for the test run.
185 https://rt.cpan.org/Ticket/Display.html?id=57518
187 Imager 0.75 - 20 Jun 2010
190 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
195 - an opacity fill based on a fountain fill would segfault when
196 filling an 8-bit/sample image.
198 - merge thickline branch polygon fix
199 https://rt.cpan.org/Ticket/Display.html?id=43518
201 Imager 0.74 - 7 May 2010
206 - read_multi() didn't handle a missing file format library correctly,
207 aborting on failing to call i_readgif_multi_wiol() or
208 i_readtiff_multi_wiol().
210 - fix spelling errors patched by Debian
211 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
213 - add an (unshipped) author test to spellcheck Imager's POD.
215 - update the TIFF file format documentation
216 https://rt.cpan.org/Ticket/Display.html?id=56510
218 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
220 Imager 0.73 - 15 Mar 2010
223 - implement outline circles, both anti-aliased and not
224 https://rt.cpan.org/Ticket/Display.html?id=19755
226 - a combine => "none" fill to a 1 or 3 channel image would produce
227 the incorrect colour.
229 Imager 0.72 - 09 Dec 2009
232 Bump version for release, since 0.71_03 is stable with CPAN testers.
234 Imager 0.71_03 - 5 Dec 2009
237 - further adjust the threads test so it only performs the tests on
238 perls where it's expected to work, and only if the threads module
241 Imager 0.71_02 - 1 Dec 2009
244 - adjust the way we load the threads module for the threads test so
245 it works with non-threaded perls
247 Imager 0.71_01 - 30 Nov 2009
252 - use scanline oriented operations to flip images instead of pixel
254 https://rt.cpan.org/Ticket/Display.html?id=39278
256 - use double/sample operations to flip large sample images instead of
257 8-bit sample operations.
258 https://rt.cpan.org/Ticket/Display.html?id=39280
261 https://rt.cpan.org/Ticket/Display.html?id=51874
263 - prevent double-frees when someone creates Imager objects and then
264 creates a thread. Note: this just handles some simple cases,
265 Imager doesn't support perl threads, and isn't likely to.
266 https://rt.cpan.org/Ticket/Display.html?id=52268
268 Imager 0.71 - 16 Nov 2009
271 - add the opacity fill type - an adaptor that modifies the opacity of
276 - the conv filter now enforces that the sum of the coefficients is
277 non-zero. Also, rather than skipping pixels off the edge off the
278 edge of the image, the closest edge pixel is used. Previously
279 dividing by the zero sum of coefficients could cause invalid
280 results or runtime exceptions.
281 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
284 Imager 0.70 - 21 Sep 2009
289 - release image row and comments memory on all error returns in gif
292 - handle zero length extensions, previously this would cause a null
294 Thanks to Krzysztof WojtaÅ for the test data and fix for this.
296 - an integer division meant that preview scaling to below 1 pixel
297 wide or high (which isn't too useful anyway) was calculating using
298 NaNs on most platforms, and causing an exception on others.
299 Thanks to David Cantrell for producing a backtrace of the crash on
300 his Alpha-NetBSD CPAN test box which made it possible to track this
303 Imager 0.69 - 08 Sep 2009
308 - broken test fix - was attempting to call a function skip_all, when
309 that should be a parameter to plan().
311 - briefly document apidocs.perl, the tool used to build
312 Imager::APIRef and make some minor enhancements
314 - various minor documentation enhancements and fixes.
316 Imager 0.68 - 07 Sep 2009
319 - Imager->new(file => $filename) and other similar incantations will
321 https://rt.cpan.org/Ticket/Display.html?id=48261
325 - avoid using CHECK as a label in Imager::Test
326 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
328 - re-work most image file test files that require a library into
329 separate library present/not present files to remove stupidly long
332 - don't treat rubthrough() outside the bounds of the target image as
334 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
336 Imager 0.67_01 - 02 Sep 2009
341 - correct documentation of default of raw image interleave read
343 https://rt.cpan.org/Ticket/Display.html?id=42074
345 - add raw_ prefix to raw read parameters, though the original names
348 - fail the read if an invalid raw_interleave parameter is supplied
350 - warn if no interleave or raw_interleave parameter is supplied,
351 since the documented default was wrong, and incompatible with the
354 - for reading raw images, if raw_storechannels > raw_datachannels,
355 set the extra channels in the image to 0
357 - when probing for executables like freetype-config, search for .bat
358 and .cmd on MSWin32, as well as .exe.
359 https://rt.cpan.org/Ticket/Display.html?id=49275
361 - re-work the external libraries section of README:
362 - list Debian and Redhat package names for each library
366 - use the new EU::MM META_MERGE facility instead of generating
367 META.yml from scratch
368 https://rt.cpan.org/Ticket/Display.html?id=47888
370 - use Devel::CheckLib (bundled, modified) to check which release of
371 libtiff is installed and reject 3.9.0
372 http://bugzilla.maptools.org/show_bug.cgi?id=2088
373 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
375 Imager 0.67 - 12 Dec 2008
380 - fix a packaging error
382 Imager 0.66 - 12 Dec 2008
385 - 24-bit color .ICO/.CUR files can now be read.
389 - an optimization skipping 0 src alpha values could cause the
390 rubthrough() to read past the end of a buffer.
391 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
393 - corrected a reference leak where writing GIFs would leak memory.
394 This could also happen calling to_paletted().
395 Also documented the underlying long existing feature where the
396 colors parameter is filled with the generated color table and added
398 http://rt.cpan.org/Ticket/Display.html?id=41028
400 - write out the image size in bytes field of a BMP correctly.
401 http://rt.cpan.org/Ticket/Display.html?id=41406
403 - add limited tests for Imager::ExtUtils
405 - make Imager::ExtUtils->includes use an absolute path, since
406 a relative path could cause failures using Inline::C.
407 http://rt.cpan.org/Ticket/Display.html?id=37353
409 - re-arrange the POD for Imager::Font::BBox:
410 - mark total_width(), pos_width(), end_offset() obsolete, since
411 they're mostly for backwards compatibility
412 - group width methods and height methods
413 https://rt.cpan.org/Ticket/Display.html?id=39999
415 Imager 0.65 - 20 May 2008
420 - In some cases when an error occurs reading those parts of a JPEG
421 file after the image the scan-line buffer could be freed a second
422 time. In cases where the the error occured while reading the image
423 data it's possible that the buffer could have leaked.
424 Thanks to Gabriel Vasseur for reporting this and help in tracking
427 - the gif_screen_height tag was overriding the screen width and being
428 ignored for the screen height when present.
429 https://rt.cpan.org/Public/Bug/Display.html?id=35568
431 Imager 0.64 - 23 April 2008
434 This is a bug fix release. This includes a fix for a possible
439 - Possible security issue: The floating point sample path for image
440 based fills had a buffer overflow. This would overwrite the end of
441 a malloc()ed buffer with double precision floats.
442 http://rt.cpan.org/Ticket/Display.html?id=35324
445 - check that the result of fileno($fh) is defined rather than simply
446 true when read() or write() is supplied with an fh parameter.
447 http://rt.cpan.org/Ticket/Display.html?id=35139
449 - i_scale_axis() wasn't checking the result of i_img_new_ch()
450 resulting in a SIGSEGV when attempting to scale an image to a size
451 too large to fit in memory. This is a NULL pointer access issue,
452 not a buffer overflow.
453 Added a check for the failure.
454 scale_calculate() (and hence scale()) will now fail if any of the
455 scale size parameters are a reference.
456 http://rt.cpan.org/Ticket/Display.html?id=35172
458 - Regression: filling a greyscale image with a hatch used the wrong
459 color channels from the supplied fg/bg colors.
460 https://rt.cpan.org/Ticket/Display.html?id=35278
462 - fixed a related problem for image fills.
464 Imager 0.63 - 7 April 2008
467 This release primarily contains changes to improve ease of use -
468 rather than you having to convert images to the appropriate number of
469 channels, Imager handles it internally. How to handle drawing colors
470 and the default combine mode is a thornier problem left for some other
473 - the font libraries are now only initialized when needed.
474 http://rt.cpan.org/Ticket/Display.html?id=28825
476 - moved the imtoc.perl code into Imager::Preprocess
478 - paste() and rubthrough() now adapt the source image data to the
479 destination, so you can now safely paste/rubthrough from greyscale
480 images to color images or back, or from alpha channel images to
481 noalpha channels or back.
482 https://rt.cpan.org/Ticket/Display.html?id=30908
484 - rubthrough() now falls back to pasting when the source doesn't have
485 an alpha channel. This effectively treats the source as having a
486 max alpha channel, the right thing to do.
487 http://rt.cpan.org/Ticket/Display.html?id=29944
489 - re-worked most of the area filling code to use a common set of
490 functions when filling.
491 Corrected normal combine mode.
492 Rewrote most of the combine modes to match the way the SVG draft
493 defines them with respect to a translucent source and destination.
494 Added tests for translucent source and destination.
495 Added tests to check 8-bit/sample and double/sample combines work
497 https://rt.cpan.org/Ticket/Display.html?id=29879
499 - writing a 2 or 4 channel image to a JPEG file will now write that
500 image as if composited against a background, black by default,
501 overridable with the i_background tag/parameter.
502 https://rt.cpan.org/Ticket/Display.html?id=29876
504 - writing a 2 or 4 channel image to a PGM/PPM file will now write
505 that image as if composited against a background, black by default,
506 overridable with the i_background tag/parameter.
507 http://rt.cpan.org/Ticket/Display.html?id=30074
509 - writing a 2 or 4 channel image to a BMP file will now write that
510 image as if composited against a background, black by default,
511 overridable with the i_background tag/parameter.
512 http://rt.cpan.org/Ticket/Display.html?id=30075
516 - Imager::Matrix2d->translate() now only requires one of the x or y
518 http://rt.cpan.org/Ticket/Display.html?id=29937
520 - mixing qtype scaling now sets all channels of a pixel to zero if
521 the pixel has zero coverage (zero alpha). This should produce more
522 compressible output files.
523 http://rt.cpan.org/Ticket/Display.html?id=32324
525 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
527 https://bugzilla.redhat.com/show_bug.cgi?id=166254
528 I'm not changing the #! lines of the sample code, since it's sample
529 code, not intended for installation.
530 http://rt.cpan.org/Ticket/Display.html?id=33408
532 - some TGA images weren't being detected correctly as TGA images
533 https://rt.cpan.org/Ticket/Display.html?id=32925
535 - handling of the left-over bit for 16-bit/pixel TGA images has been
536 changed to match the behaviour of the GIMP. Previously the bit
537 being set was treated as an opaque pixel, but one user reported a
538 problem with loading such an image. I haven't been able to find any
539 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
540 I'll match it's behaviour. See issue 114913 in the GIMP's
542 http://rt.cpan.org/Ticket/Display.html?id=32926
544 Imager 0.62 - 10 December 2007
547 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
548 to /path under your home directory.
549 http://rt.cpan.org/Ticket/Display.html?id=29484
551 - the old dynaload code used Mach API functions to load dynamic
552 libraries on Mac OS X. These APIs have been deprecated in OS X
553 10.5 and were causing some build problems.
554 So henceforth Imager uses the dlopen() family of functions, and you
555 will need version 10.3 or later of OS X.
557 - added the det() function to the transform2() engine.
558 added the sample quad_to_square.pl
559 Courtesy Richard Fairhurst.
560 http://rt.cpan.org/Ticket/Display.html?id=31244
564 - samples/gifscale.pl sourced the base value for gif_top from
566 Thanks to Eleneldil G. Arilou for pointing this out.
568 - t/t82inline.t no longer loads B at runtime, to work around a bug
569 in some 5.005_0[45] installations.
570 http://rt.cpan.org/Ticket/Display.html?id=30508
572 - work around Module::Depends::Intrusive bug #21229
573 http://rt.cpan.org/Ticket/Display.html?id=30520
575 - the hardinvert filter no-longer inverts the alpha channel.
576 http://rt.cpan.org/Ticket/Display.html?id=30002
578 - the hardinvert filter now supports large samples
580 Imager 0.61_02 - 28 November 2007
583 - major TIFF support re-work
584 http://rt.cpan.org/Ticket/Display.html?id=20329
586 - added a C level image interface for accessing samples from 1-32
587 bits, exposed this at the perl level in getsamples()
589 - the conv filter now works at floating point precision for high bit
592 - added is_bilevel method to test whether an image should be written as
593 a bilevel image if the image format supports it.
595 - added -log-stderr as an Imager import list option
597 - added some important types to Imager::APIRef
599 - added test_image_double() to Imager::Test
603 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
606 - the scale() method with qtype mixing now handles images with an
607 alpha channel correctly.
609 - fixed a broken link from the "animated GIF" entry in the concept index.
610 Thanks to Slaven Rezic.
611 http://rt.cpan.org/Ticket/Display.html?id=30889
613 - on some perl's the infix expression parser test would fail due to
614 actions in the grammar returning false. Made sure all actions return
616 Thanks to Richard Fairhurst for spending a lot of time in tracking
618 http://rt.cpan.org/Public/Bug/Display.html?id=29562
620 Imager 0.61 - 5 November 2007
623 - added samples/gifscale.pl, which adjusts the screen size/position tags
624 when scaling an animated gif
625 http://rt.cpan.org/Ticket/Display.html?id=27591
629 - correct handling of sz in matrix_transform() - this should allow
630 perspective type transformations to work now.
631 http://rt.cpan.org/Ticket/Display.html?id=29936
633 - prevent a cast to integer warning on x64 builds in datatypes.c
634 also fixed some other type warnings
635 https://rt.cpan.org/Ticket/Display.html?id=30204
637 - some sub-directory tests depended on files produced by the parent
639 http://rt.cpan.org/Ticket/Display.html?id=30203
641 - Imager::Font::Wrap doesn't correctly set savepos
642 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
643 http://rt.cpan.org/Ticket/Display.html?id=29771
645 - test 171 in t/t01introvert.t was failing on perls configured to
647 http://rt.cpan.org/Ticket/Display.html?id=29413
649 - the code for the transform2() uminus operator was missing a break.
650 Added tests for better code coverage of the ops.
651 http://rt.cpan.org/Ticket/Display.html?id=29296
653 - the SGI RLE compression code could overflow its compression buffer
654 http://rt.cpan.org/Ticket/Display.html?id=30334
656 - the 32-bit output function used by the SGI code only handled values
657 under 0x10000. This was most noticable when writing large RLE images.
658 http://rt.cpan.org/Ticket/Display.html?id=30335
660 - validate chan_count for chans == NULL for each of the i_gsamp()
662 http://rt.cpan.org/Ticket/Display.html?id=28985
664 - attempt to work around the test failure at
665 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
666 http://rt.cpan.org/Ticket/Display.html?id=29562
668 - improve the error messages produced when attempting to read or write
669 an unknown image file format.
670 http://rt.cpan.org/Ticket/Display.html?id=30103
672 - improve the transform2() documentation
673 http://rt.cpan.org/Ticket/Display.html?id=29267
675 - correctly generate the author key in META.yml
676 http://rt.cpan.org/Ticket/Display.html?id=30377
678 - correctly blend a rotated (or matrix_transformed()) image when
679 performing interpolation in the presence of an alpha channel.
680 Also corrected the centring of the rotated image on the output
683 Imager 0.60 - 30 August 2007
686 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
687 now has full SGI RGB image format, including RLE and 16-bit/sample
689 https://rt.cpan.org/Ticket/Display.html?id=8666
691 - logging functions are now available in the API
693 - applied Gabriel Vasseur's patch
694 added documentation, further tests, and support for greyscale images
695 Obviously problems are my fault :)
696 https://rt.cpan.org/Ticket/Display.html?id=28142
698 - the mask for ICO/CUR images is now applied as an alpha channel to
699 the returned image. For the old behaviour, supply ico_masked => 0
700 to read() or read_multi(). This should be less confusing when
701 using Imager as a general image processor.
702 https://rt.cpan.org/Ticket/Display.html?id=29001
706 - in some cases it's possible for giflib/libungif to return color
707 indexes outside the range of colors defined by the image's palette.
708 We now expand the palette to match the indexes used.
709 Thanks to Gabriel Vasseur for reporting this.
711 - fixed various memory leaks that could occur when failing to read png,
712 jpeg, bmp or tga files.
714 - to avoid confusion, channels not present in the image are returned as
715 zero by getscanline(). This has no effect on the C level i_glin()
716 and i_glinf() API functions which continue to not set the unused
719 - the convert() method now returns an image of the same sample size as
721 https://rt.cpan.org/Ticket/Display.html?id=28492
723 - remove repeated text in Imager::Files
724 http://rt.cpan.org/Ticket/Display.html?id=27589
726 - be even more explicit that scale() and friends don't modify the source
727 image, but return a new image.
728 http://rt.cpan.org/Ticket/Display.html?id=28570
730 - improve the error message from errstr() when you try to load a font
731 for which the driver hasn't been built in Imager.
732 http://rt.cpan.org/Ticket/Display.html?id=27571
734 - transparency is now enabled by default when writing GIF images
735 http://rt.cpan.org/Ticket/Display.html?id=27615
737 - Imager would not load on Windows 98
738 http://rt.cpan.org/Ticket/Display.html?id=27653
740 Imager 0.59 - 14 June 2007
745 - fixes a regression introduced by the fixes for RT 11972
746 http://rt.cpan.org/Ticket/Display.html?id=27546
748 - cropping outside the image would return an Imager object with
749 no low-level image object, instead of returning false.
750 Fixed by: Philip Gwyn (Leolo)
751 http://rt.cpan.org/Ticket/Display.html?id=27509
753 Imager 0.58 - 16 May 2007
756 No significant changes from 0.57_01.
758 Imager 0.57_01 - 11 May 2007
761 - added to_rgb16 to produce a 16-bit/sample version of an image
763 - improve freetype 1.x text output efficiency
767 - search another place for rgb.txt, and check all the places
768 Imager::Color checks when deciding whether to skip testing it
769 http://rt.cpan.org/Ticket/Display.html?id=26064
771 - use a convolution kernel size based on the stddev rather than a
772 fixed size when performing a gaussian blur
773 http://rt.cpan.org/Ticket/Display.html?id=25645
775 - document the difference() method's mindist parameter, and debug it.
777 - put the Imager release number in the Inline::C generated code to
778 regenerate Inline code when a new release of Imager is installed.
779 http://rt.cpan.org/Ticket/Display.html?id=26278
781 - fix rendering on alpha channel images for the FreeType 1.x driver.
782 http://rt.cpan.org/Ticket/Display.html?id=11972
784 - fix rendering on alpha channel images for the T1lib driver.
785 http://rt.cpan.org/Ticket/Display.html?id=11972
787 - reworked library probing, we can now set more than one probe
788 function for a library. Disabled the default (non-freetype-config)
789 library probe and added an extra probe function that searches for
790 both ft2build.h and whatever it includes, and adds -I as needed.
791 Hopefully this will fix build problems like

793 http://rt.cpan.org/Ticket/Display.html?id=26086
795 Imager 0.57 - 30 Apr 2007
798 This is a maintenence release fixing a security issue in Imager.
800 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
801 overflow in malloced memory. There will be further discussion of
802 this issue in the ticket below.
803 http://rt.cpan.org/Ticket/Display.html?id=26811
804 CVE-2007-2459 CVE-2007-2413
805 The descriptions at cve.mitre.org varied in quality, please see the
806 ticket at rt.cpan.org for a more accurate description of the issue.
808 Imager 0.56 - 1 Apr 2007
811 - added support for reading 16-bit/sample PGM/PPM images
813 - added support for writing 16-bit/sample PGM/PPM images
815 - improved performance of reading PBM/PGM/PPM images
817 - added support for writing PBM images if the image is paletted and
818 contains only black and white
820 - added a new make_colors value - "mono"
822 - switched from the svn log Changes to a manual Changes to reduce
825 - new sample code - samples/flasher.pl
829 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
830 was returning an image object with an extra reference, this
831 resulted in a memory leak.
832 http://rt.cpan.org/Ticket/Display.html?id=24992
834 - fix rendering on alpha channel images for the FreeType 2.x driver
835 http://rt.cpan.org/Ticket/Display.html?id=11972
837 - reading bmp files now consitently handles short reads. You can now
838 supply a parameter to treat a short read as successful and set
840 http://rt.cpan.org/Ticket/Display.html?id=8426
842 - previously, reading ASCII PBM files required spaces between samples,
843 even though the format doesn't require that
845 - improved documentation of the unsharpmask filter (I hope)
846 http://rt.cpan.org/Ticket/Display.html?id=25531
848 - force flushing of the output from i_tt_dump_names() and test output
849 in t/t35ttfont.t to prevent output from being mixed up.
850 https://rt.cpan.org/Ticket/Display.html?id=24859
852 - rewrite a conditional expression as an if() to hopefully work around
853 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
854 https://rt.cpan.org/Ticket/Display.html?id=25561
856 - avoid Data::Dumper in regops.perl to support older releases of perl
857 https://rt.cpan.org/Ticket/Display.html?id=24391
859 Imager 0.55 - 16 Dec 2006
862 This is primarily a bug fix release.
864 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
866 There is one new feature:
868 - the Win32 font driver now supports UTF8 (RT 22166)
869 http://www.cpanforum.com/threads/3276
870 http://rt.cpan.org/Ticket/Display.html?id=22166
872 Several bugs were fixed:
874 - the string() method would not output the string "0"
875 http://rt.cpan.org/Public/Bug/Display.html?id=21770
877 - fills.c was failing to compile on Solaris 10 (compiler unknown)
878 http://rt.cpan.org/Public/Bug/Display.html?id=21944
880 - the gif_disposal and gif_user_input tags weren't being read from
882 http://rt.cpan.org/Public/Bug/Display.html?id=22192
884 - gif.c was failing to build under MSVC
885 http://rt.cpan.org/Ticket/Display.html?id=23922
887 - in some cases strings passed to the string() method were treated as
888 terminated by NUL (chr 0)
889 http://rt.cpan.org/Public/Bug/Display.html?id=21770
891 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
892 that's the default build name for zlib on Win32.
893 http://rt.cpan.org/Ticket/Display.html?id=23064
895 - search $Config{incpath} for headers too, which we should have been
898 Win32 font driver fixes:
900 - the global descent value from bounding box was the wrong sign
901 http://www.cpanforum.com/threads/3276
903 - if the first or last glyph overflowed the left or right side of the
904 advance width they would be clipped
907 Imager 0.54 - 14 Sep 2006
910 This is primarily a feature release:
912 - a new qtype value 'mixing' has been added to the scale()
913 method. This is faster than 'normal', slower than 'preview'. This
914 is based on the method used by pnmscale, and seems to produce less
915 blurry results than normal.
916 http://rt.cpan.org/Public/Bug/Display.html?id=20677
918 - the rubthrough() method can now render onto images with an alpha
920 http://rt.cpan.org/Ticket/Display.html?id=20678
922 - the read_multi() method now falls back to calling doing a single
923 image read via the read() method and write_multi() will now fall
924 back to calling write() if a single image is supplied. This means
925 you can simply call the read_multi() or write_multi() functions
926 without having to check if the type is formatted by that method.
927 http://rt.cpan.org/Ticket/Display.html?id=19457
928 http://rt.cpan.org/Ticket/Display.html?id=19458
930 - the GIF loop extension can now be written. If you don't have
931 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
933 http://rt.cpan.org/Ticket/Display.html?id=21185
935 - getscanline() and setscanline() can now read/write palette index
936 based data from/to the image for paletted images, by setting type to
938 http://rt.cpan.org/Ticket/Display.html?id=20338
940 - we no longer hassle you to disable GIF support
941 http://rt.cpan.org/Ticket/Display.html?id=20687
943 - minor documentation fixes
946 Imager 0.53 - 26 Jul 2006
949 This is a bugfix release.
951 Some test code was left in a code path not covered by the test
952 suite. A test was added to cover this code path and the test code was
954 http://rt.cpan.org/Public/Bug/Display.html?id=20705
957 Imager 0.52 - 25 Jul 2006
960 This is primarily a feature release, but contains a fair few bug
963 - ability to read and write MS Windows ICO and CUR files
965 - you can now add file format plugins to support new file formats
967 - add POD coverage tests
969 - setcolors() and addcolors() now accept color names and so on
970 instead of requiring Imager::Color objects.
971 http://rt.cpan.org/Ticket/Display.html?id=20056
973 - flood_fill() can now fill to a specified border color instead of
974 just to the area the same color as the seed.
975 http://rt.cpan.org/Ticket/Display.html?id=19618
980 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
981 calculating the advance width.
982 http://rt.cpan.org/Public/Bug/Display.html?id=20554
984 - bounding_box for the T1 driver wasn't including leading and
985 trailing spaces in the bounding box as the other drivers did, it also
986 produced strange results for empty strings or strings containing only
989 - when reading CMYK jpeg images they were being transferred to the
990 image object as is, producing a four channel image. It only looked ok
991 due to an old still unfixed Photoshop bug. We now convert from the
992 inverted CMYK that photoshop (and Corel for example) produce into RGB.
993 http://rt.cpan.org/Ticket/Display.html?id=20416
995 - reading a CYMK TIFF would result in a 4 channel image, reading any
996 image with more than 4 channels (eg. RGB with 2 alpha channels) would
998 http://rt.cpan.org/Ticket/Display.html?id=20415
1000 - added /usr/local/include to the default include search path, since
1001 we were already searching /usr/local/lib for libraries.
1003 And various minor fixes and documentation updates.
1006 Imager 0.51 - 23 Apr 2006
1009 - fix a validation bug when processing JPEG EXIF data that can cause
1011 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1013 - fix mis-processing of the src_maxx and src_maxy parameters of the
1015 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1017 - fix a problem in Imager's "smart" handling of the color parameter
1019 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1022 Imager 0.50 - 29 Mar 2006
1025 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1026 or 4 channel image to jpeg or a 2 channel image to tga where the
1027 output is an in-memeory buffer.
1028 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1030 - fixes an incorrect pointer parameter in the PNG code
1031 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1033 - skip Inline::C tests when building in a directory with spaces
1034 http://rt.cpan.org/Public/Bug/Display.html?id=18049
