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 - increase the version of Imager::Font::Type1 so that upgrades don't
28 downgrade the version in this file.
29 https://rt.cpan.org/Ticket/Display.html?id=66250
31 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
32 that option for the directories that would normally go in
33 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
34 https://rt.cpan.org/Ticket/Display.html?id=65955
36 Imager 0.81 - 14 Feb 2011
39 - added coverage tests for masked images (maskimg.c @100% test coverage)
41 - add hsv() method to Imager::Color
42 Thanks to Leolo (Philip Gwyn)
43 https://rt.cpan.org/Ticket/Display.html?id=65385
45 - split libt1 Type 1 font support into a sub-module
46 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
48 - add a preload() class method for use in forking servers, and to
49 work around limitations in PAR.
50 https://rt.cpan.org/Ticket/Display.html?id=65665
54 - paletted writes to a masked image are now masked correctly.
55 Revealed by new coverage tests.
57 - update the filter plugin documentation.
58 https://rt.cpan.org/Ticket/Display.html?id=56513
60 - add the matrix() method to Imager::Matrix2d to allow creation of a
61 matrix with specified co-efficients. You can now multiple an
62 Imager::Matrix2d object by a 9 element array ref or a number.
63 https://rt.cpan.org/Ticket/Display.html?id=29938
65 - really fix loading TTF fonts with FT2 when FT1 isn't available.
66 Thanks to Leolo (Philip Gwyn)
67 https://rt.cpan.org/Ticket/Display.html?id=65386
68 https://rt.cpan.org/Ticket/Display.html?id=62855
70 - make sure each test script that needs testout/ creates it.
71 https://rt.cpan.org/Ticket/Display.html?id=65088
73 - handle a slightly different warning from libtiff 4.x
74 https://rt.cpan.org/Ticket/Display.html?id=65268
76 - the sat transform2() op returned an incorrect saturation.
77 https://rt.cpan.org/Ticket/Display.html?id=65391
79 Imager 0.80 - 17 Jan 2011
82 - added coverage tests for Imager::Fountain and Imager::Color::Float
84 - Imager is now maintained in git
85 http://git.imager.perl.org/imager.git
86 git://git.imager.perl.org/imager.git
90 - images with an translucent alpha channel were not scaled correctly
91 by the default (qtype=normal) scaling method.
92 https://rt.cpan.org/Public/Bug/Display.html?id=63922
94 - Imager::Color::Float now translates "#FFFFFF" to white instead of
97 - make the default color map build algorithm "mediancut". This
98 changes the default color map builder for writing GIFs back to what
99 it was in 0.77, reverting a performance regression.
100 https://rt.cpan.org/Ticket/Display.html?id=64785
102 - handle failure to create a masked image correctly
104 Imager 0.79 - 10 Dec 2010
107 - add Imager::Test to the POD coverage tests and document the missing
110 - the convert() method now optimizes the case where all output
111 channels are either 0, sourced from a single input channel or 1.
112 This significantly speeds up presets like "addalpha", "green".
113 https://rt.cpan.org/Ticket/Display.html?id=51254
115 - add wiggle.pl sample, as suggested by Dan Oppenheim.
117 - add the combine() method to combine channels from multiple source
118 images into a new image
119 https://rt.cpan.org/Ticket/Display.html?id=11872
123 - treat the co-efficients for convert() as doubles instead of floats.
125 - If a higher (earlier) priority font handler failed to load, that
126 would crash preventing loading of later font handlers.
127 https://rt.cpan.org/Ticket/Display.html?id=62855
129 - parse defines from the options returned by pkg-config --cflags
130 https://rt.cpan.org/Ticket/Display.html?id=63223
132 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
133 included in the tarball. They are now included.
135 Imager 0.78 - 4 Oct 2010
140 - don't access deprecated members of the png_structp.
141 https://rt.cpan.org/Ticket/Display.html?id=60242
143 - document that using color objects is faster than supplying colors
145 https://rt.cpan.org/Ticket/Display.html?id=61047
147 - Imager::Probe now accepts array references for incpath and libpath.
148 https://rt.cpan.org/Ticket/Display.html?id=60244
150 Imager 0.77_02 - 27 Sep 2010
153 - moved Win32, FreeType 2 font support into sub-modules.
154 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
155 Uses Imager::Probe now.
156 https://rt.cpan.org/Public/Bug/Display.html?id=61328
158 - tested successfully with jpeg-8b
159 https://rt.cpan.org/Ticket/Display.html?id=60221
163 - from _01: look for missing file support test files in the right
166 - flood_fill() wouldn't fill the right side of a single scan-line
168 Thanks to Nicolas Roggli for reporting this.
170 - flood_fill wouldn't fill to the left edge of the image if the
171 starting line didn't reach the left edge.
172 Thanks to Nicolas Roggli for reporting this.
174 Imager 0.77_01 - 13 Sep 2010
177 - add each library-directory/pkgconfig/ to the pkg-config search path
179 Thanks to Justin Davis.
180 https://rt.cpan.org/Ticket/Display.html?id=60491
182 - moved GIF, TIFF, JPEG file handling code into sub-modules in
183 preparation for separate distribution.
184 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
186 - optimize filled box drawing (color, not fill)
190 - Imager::Probe was calling ExtUtils::Liblist to initialize
191 LD_RUN_PATH supplying an undefined value rather than the found
192 directory. Thanks to Justin Davis.
193 https://rt.cpan.org/Ticket/Display.html?id=60491
195 - only prepend ./ to font filenames when passing them to T1Lib and
196 then only when it would use its search mechanisms.
197 https://rt.cpan.org/Ticket/Display.html?id=60509
199 - fix the cache check for the X rgb.txt loader. This is typically
200 used for color translation on Unix-like systems, and the fix
201 improves performance of supplying colors by name by about 80 times.
202 Test code that managed 3400 10x10 pixel boxes/second sped up to
205 - clarify that Imager doesn't write EXIF metadata to images.
206 https://rt.cpan.org/Ticket/Display.html?id=60637
208 - Imager::Probe can now search subdirectories under its include path.
209 Used by the PNG Makefile.PL to find headers and libraries when they
210 aren't in the base directory, as in cygwin.
211 https://rt.cpan.org/Ticket/Display.html?id=60635
213 Imager 0.77 - 11 Aug 2010
216 I don't want Imager::File::PNG indexed as part of Imager, but forgot
217 to update the META.yml before updating the version.
219 - don't index Imager::File::PNG as part of Imager
221 - add resources to META.yml
223 Imager 0.76 - not released
228 - the align_string() method would ignore a string of "0" due to a
230 Thanks to Maurice Height for reporting this.
231 https://rt.cpan.org/Ticket/Display.html?id=60199
233 Imager 0.75_03 - 09 Aug 2010
238 - read_types() and write_types() would include png when it wasn't
239 available due to a problem with the %formats tie
241 - handle dependent libraries correctly (eg -lpng requiring -lz) in
242 the code run phase of library probing.
244 Imager 0.75_02 - 07 Aug 2010
249 - add file missing from MANIFEST, which was causing TIFF failures.
251 Imager 0.75_01 - 06 Aug 2010
254 Test release for the new PNG probe.
256 - added the ability to read multiple-image PNM files.
257 Note that unlike the pbm/pgm/ppm specification this accepts mixed
258 format files and allows white space padding between files.
259 Thanks to Philip Gwyn (Leolo) for this patch.
261 - moved the PNG file handling code into a sub-module in preparation
262 for separate distribution.
263 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
264 Also helps avoid complications from -I/-L compile/link options from
269 - Imager->new(data => $data) didn't try to process image file data in
271 https://rt.cpan.org/Ticket/Display.html?id=58761
273 - t/t50basicoo.t no longer depends on the other tests to generate its
275 https://rt.cpan.org/Ticket/Display.html?id=9798
276 Also, it wasn't testing pnm (pnm vs ppm mix-up)
278 - update the documentation of hardinvert to match the change in 0.62.
279 https://rt.cpan.org/Ticket/Display.html?id=59785
281 - added hardinvertall filter which also inverts the alpha channel
284 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
285 the probe can find the library for the test run.
286 https://rt.cpan.org/Ticket/Display.html?id=57518
288 Imager 0.75 - 20 Jun 2010
291 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
296 - an opacity fill based on a fountain fill would segfault when
297 filling an 8-bit/sample image.
299 - merge thickline branch polygon fix
300 https://rt.cpan.org/Ticket/Display.html?id=43518
302 Imager 0.74 - 7 May 2010
307 - read_multi() didn't handle a missing file format library correctly,
308 aborting on failing to call i_readgif_multi_wiol() or
309 i_readtiff_multi_wiol().
311 - fix spelling errors patched by Debian
312 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
314 - add an (unshipped) author test to spellcheck Imager's POD.
316 - update the TIFF file format documentation
317 https://rt.cpan.org/Ticket/Display.html?id=56510
319 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
321 Imager 0.73 - 15 Mar 2010
324 - implement outline circles, both anti-aliased and not
325 https://rt.cpan.org/Ticket/Display.html?id=19755
327 - a combine => "none" fill to a 1 or 3 channel image would produce
328 the incorrect colour.
330 Imager 0.72 - 09 Dec 2009
333 Bump version for release, since 0.71_03 is stable with CPAN testers.
335 Imager 0.71_03 - 5 Dec 2009
338 - further adjust the threads test so it only performs the tests on
339 perls where it's expected to work, and only if the threads module
342 Imager 0.71_02 - 1 Dec 2009
345 - adjust the way we load the threads module for the threads test so
346 it works with non-threaded perls
348 Imager 0.71_01 - 30 Nov 2009
353 - use scanline oriented operations to flip images instead of pixel
355 https://rt.cpan.org/Ticket/Display.html?id=39278
357 - use double/sample operations to flip large sample images instead of
358 8-bit sample operations.
359 https://rt.cpan.org/Ticket/Display.html?id=39280
362 https://rt.cpan.org/Ticket/Display.html?id=51874
364 - prevent double-frees when someone creates Imager objects and then
365 creates a thread. Note: this just handles some simple cases,
366 Imager doesn't support perl threads, and isn't likely to.
367 https://rt.cpan.org/Ticket/Display.html?id=52268
369 Imager 0.71 - 16 Nov 2009
372 - add the opacity fill type - an adaptor that modifies the opacity of
377 - the conv filter now enforces that the sum of the coefficients is
378 non-zero. Also, rather than skipping pixels off the edge off the
379 edge of the image, the closest edge pixel is used. Previously
380 dividing by the zero sum of coefficients could cause invalid
381 results or runtime exceptions.
382 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
385 Imager 0.70 - 21 Sep 2009
390 - release image row and comments memory on all error returns in gif
393 - handle zero length extensions, previously this would cause a null
395 Thanks to Krzysztof Wojtaś for the test data and fix for this.
397 - an integer division meant that preview scaling to below 1 pixel
398 wide or high (which isn't too useful anyway) was calculating using
399 NaNs on most platforms, and causing an exception on others.
400 Thanks to David Cantrell for producing a backtrace of the crash on
401 his Alpha-NetBSD CPAN test box which made it possible to track this
404 Imager 0.69 - 08 Sep 2009
409 - broken test fix - was attempting to call a function skip_all, when
410 that should be a parameter to plan().
412 - briefly document apidocs.perl, the tool used to build
413 Imager::APIRef and make some minor enhancements
415 - various minor documentation enhancements and fixes.
417 Imager 0.68 - 07 Sep 2009
420 - Imager->new(file => $filename) and other similar incantations will
422 https://rt.cpan.org/Ticket/Display.html?id=48261
426 - avoid using CHECK as a label in Imager::Test
427 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
429 - re-work most image file test files that require a library into
430 separate library present/not present files to remove stupidly long
433 - don't treat rubthrough() outside the bounds of the target image as
435 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
437 Imager 0.67_01 - 02 Sep 2009
442 - correct documentation of default of raw image interleave read
444 https://rt.cpan.org/Ticket/Display.html?id=42074
446 - add raw_ prefix to raw read parameters, though the original names
449 - fail the read if an invalid raw_interleave parameter is supplied
451 - warn if no interleave or raw_interleave parameter is supplied,
452 since the documented default was wrong, and incompatible with the
455 - for reading raw images, if raw_storechannels > raw_datachannels,
456 set the extra channels in the image to 0
458 - when probing for executables like freetype-config, search for .bat
459 and .cmd on MSWin32, as well as .exe.
460 https://rt.cpan.org/Ticket/Display.html?id=49275
462 - re-work the external libraries section of README:
463 - list Debian and Redhat package names for each library
467 - use the new EU::MM META_MERGE facility instead of generating
468 META.yml from scratch
469 https://rt.cpan.org/Ticket/Display.html?id=47888
471 - use Devel::CheckLib (bundled, modified) to check which release of
472 libtiff is installed and reject 3.9.0
473 http://bugzilla.maptools.org/show_bug.cgi?id=2088
474 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
476 Imager 0.67 - 12 Dec 2008
481 - fix a packaging error
483 Imager 0.66 - 12 Dec 2008
486 - 24-bit color .ICO/.CUR files can now be read.
490 - an optimization skipping 0 src alpha values could cause the
491 rubthrough() to read past the end of a buffer.
492 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
494 - corrected a reference leak where writing GIFs would leak memory.
495 This could also happen calling to_paletted().
496 Also documented the underlying long existing feature where the
497 colors parameter is filled with the generated color table and added
499 http://rt.cpan.org/Ticket/Display.html?id=41028
501 - write out the image size in bytes field of a BMP correctly.
502 http://rt.cpan.org/Ticket/Display.html?id=41406
504 - add limited tests for Imager::ExtUtils
506 - make Imager::ExtUtils->includes use an absolute path, since
507 a relative path could cause failures using Inline::C.
508 http://rt.cpan.org/Ticket/Display.html?id=37353
510 - re-arrange the POD for Imager::Font::BBox:
511 - mark total_width(), pos_width(), end_offset() obsolete, since
512 they're mostly for backwards compatibility
513 - group width methods and height methods
514 https://rt.cpan.org/Ticket/Display.html?id=39999
516 Imager 0.65 - 20 May 2008
521 - In some cases when an error occurs reading those parts of a JPEG
522 file after the image the scan-line buffer could be freed a second
523 time. In cases where the the error occured while reading the image
524 data it's possible that the buffer could have leaked.
525 Thanks to Gabriel Vasseur for reporting this and help in tracking
528 - the gif_screen_height tag was overriding the screen width and being
529 ignored for the screen height when present.
530 https://rt.cpan.org/Public/Bug/Display.html?id=35568
532 Imager 0.64 - 23 April 2008
535 This is a bug fix release. This includes a fix for a possible
540 - Possible security issue: The floating point sample path for image
541 based fills had a buffer overflow. This would overwrite the end of
542 a malloc()ed buffer with double precision floats.
543 http://rt.cpan.org/Ticket/Display.html?id=35324
546 - check that the result of fileno($fh) is defined rather than simply
547 true when read() or write() is supplied with an fh parameter.
548 http://rt.cpan.org/Ticket/Display.html?id=35139
550 - i_scale_axis() wasn't checking the result of i_img_new_ch()
551 resulting in a SIGSEGV when attempting to scale an image to a size
552 too large to fit in memory. This is a NULL pointer access issue,
553 not a buffer overflow.
554 Added a check for the failure.
555 scale_calculate() (and hence scale()) will now fail if any of the
556 scale size parameters are a reference.
557 http://rt.cpan.org/Ticket/Display.html?id=35172
559 - Regression: filling a greyscale image with a hatch used the wrong
560 color channels from the supplied fg/bg colors.
561 https://rt.cpan.org/Ticket/Display.html?id=35278
563 - fixed a related problem for image fills.
565 Imager 0.63 - 7 April 2008
568 This release primarily contains changes to improve ease of use -
569 rather than you having to convert images to the appropriate number of
570 channels, Imager handles it internally. How to handle drawing colors
571 and the default combine mode is a thornier problem left for some other
574 - the font libraries are now only initialized when needed.
575 http://rt.cpan.org/Ticket/Display.html?id=28825
577 - moved the imtoc.perl code into Imager::Preprocess
579 - paste() and rubthrough() now adapt the source image data to the
580 destination, so you can now safely paste/rubthrough from greyscale
581 images to color images or back, or from alpha channel images to
582 noalpha channels or back.
583 https://rt.cpan.org/Ticket/Display.html?id=30908
585 - rubthrough() now falls back to pasting when the source doesn't have
586 an alpha channel. This effectively treats the source as having a
587 max alpha channel, the right thing to do.
588 http://rt.cpan.org/Ticket/Display.html?id=29944
590 - re-worked most of the area filling code to use a common set of
591 functions when filling.
592 Corrected normal combine mode.
593 Rewrote most of the combine modes to match the way the SVG draft
594 defines them with respect to a translucent source and destination.
595 Added tests for translucent source and destination.
596 Added tests to check 8-bit/sample and double/sample combines work
598 https://rt.cpan.org/Ticket/Display.html?id=29879
600 - writing a 2 or 4 channel image to a JPEG file will now write that
601 image as if composited against a background, black by default,
602 overridable with the i_background tag/parameter.
603 https://rt.cpan.org/Ticket/Display.html?id=29876
605 - writing a 2 or 4 channel image to a PGM/PPM file will now write
606 that image as if composited against a background, black by default,
607 overridable with the i_background tag/parameter.
608 http://rt.cpan.org/Ticket/Display.html?id=30074
610 - writing a 2 or 4 channel image to a BMP file will now write that
611 image as if composited against a background, black by default,
612 overridable with the i_background tag/parameter.
613 http://rt.cpan.org/Ticket/Display.html?id=30075
617 - Imager::Matrix2d->translate() now only requires one of the x or y
619 http://rt.cpan.org/Ticket/Display.html?id=29937
621 - mixing qtype scaling now sets all channels of a pixel to zero if
622 the pixel has zero coverage (zero alpha). This should produce more
623 compressible output files.
624 http://rt.cpan.org/Ticket/Display.html?id=32324
626 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
628 https://bugzilla.redhat.com/show_bug.cgi?id=166254
629 I'm not changing the #! lines of the sample code, since it's sample
630 code, not intended for installation.
631 http://rt.cpan.org/Ticket/Display.html?id=33408
633 - some TGA images weren't being detected correctly as TGA images
634 https://rt.cpan.org/Ticket/Display.html?id=32925
636 - handling of the left-over bit for 16-bit/pixel TGA images has been
637 changed to match the behaviour of the GIMP. Previously the bit
638 being set was treated as an opaque pixel, but one user reported a
639 problem with loading such an image. I haven't been able to find any
640 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
641 I'll match it's behaviour. See issue 114913 in the GIMP's
643 http://rt.cpan.org/Ticket/Display.html?id=32926
645 Imager 0.62 - 10 December 2007
648 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
649 to /path under your home directory.
650 http://rt.cpan.org/Ticket/Display.html?id=29484
652 - the old dynaload code used Mach API functions to load dynamic
653 libraries on Mac OS X. These APIs have been deprecated in OS X
654 10.5 and were causing some build problems.
655 So henceforth Imager uses the dlopen() family of functions, and you
656 will need version 10.3 or later of OS X.
658 - added the det() function to the transform2() engine.
659 added the sample quad_to_square.pl
660 Courtesy Richard Fairhurst.
661 http://rt.cpan.org/Ticket/Display.html?id=31244
665 - samples/gifscale.pl sourced the base value for gif_top from
667 Thanks to Eleneldil G. Arilou for pointing this out.
669 - t/t82inline.t no longer loads B at runtime, to work around a bug
670 in some 5.005_0[45] installations.
671 http://rt.cpan.org/Ticket/Display.html?id=30508
673 - work around Module::Depends::Intrusive bug #21229
674 http://rt.cpan.org/Ticket/Display.html?id=30520
676 - the hardinvert filter no-longer inverts the alpha channel.
677 http://rt.cpan.org/Ticket/Display.html?id=30002
679 - the hardinvert filter now supports large samples
681 Imager 0.61_02 - 28 November 2007
684 - major TIFF support re-work
685 http://rt.cpan.org/Ticket/Display.html?id=20329
687 - added a C level image interface for accessing samples from 1-32
688 bits, exposed this at the perl level in getsamples()
690 - the conv filter now works at floating point precision for high bit
693 - added is_bilevel method to test whether an image should be written as
694 a bilevel image if the image format supports it.
696 - added -log-stderr as an Imager import list option
698 - added some important types to Imager::APIRef
700 - added test_image_double() to Imager::Test
704 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
707 - the scale() method with qtype mixing now handles images with an
708 alpha channel correctly.
710 - fixed a broken link from the "animated GIF" entry in the concept index.
711 Thanks to Slaven Rezic.
712 http://rt.cpan.org/Ticket/Display.html?id=30889
714 - on some perl's the infix expression parser test would fail due to
715 actions in the grammar returning false. Made sure all actions return
717 Thanks to Richard Fairhurst for spending a lot of time in tracking
719 http://rt.cpan.org/Public/Bug/Display.html?id=29562
721 Imager 0.61 - 5 November 2007
724 - added samples/gifscale.pl, which adjusts the screen size/position tags
725 when scaling an animated gif
726 http://rt.cpan.org/Ticket/Display.html?id=27591
730 - correct handling of sz in matrix_transform() - this should allow
731 perspective type transformations to work now.
732 http://rt.cpan.org/Ticket/Display.html?id=29936
734 - prevent a cast to integer warning on x64 builds in datatypes.c
735 also fixed some other type warnings
736 https://rt.cpan.org/Ticket/Display.html?id=30204
738 - some sub-directory tests depended on files produced by the parent
740 http://rt.cpan.org/Ticket/Display.html?id=30203
742 - Imager::Font::Wrap doesn't correctly set savepos
743 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
744 http://rt.cpan.org/Ticket/Display.html?id=29771
746 - test 171 in t/t01introvert.t was failing on perls configured to
748 http://rt.cpan.org/Ticket/Display.html?id=29413
750 - the code for the transform2() uminus operator was missing a break.
751 Added tests for better code coverage of the ops.
752 http://rt.cpan.org/Ticket/Display.html?id=29296
754 - the SGI RLE compression code could overflow its compression buffer
755 http://rt.cpan.org/Ticket/Display.html?id=30334
757 - the 32-bit output function used by the SGI code only handled values
758 under 0x10000. This was most noticable when writing large RLE images.
759 http://rt.cpan.org/Ticket/Display.html?id=30335
761 - validate chan_count for chans == NULL for each of the i_gsamp()
763 http://rt.cpan.org/Ticket/Display.html?id=28985
765 - attempt to work around the test failure at
766 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
767 http://rt.cpan.org/Ticket/Display.html?id=29562
769 - improve the error messages produced when attempting to read or write
770 an unknown image file format.
771 http://rt.cpan.org/Ticket/Display.html?id=30103
773 - improve the transform2() documentation
774 http://rt.cpan.org/Ticket/Display.html?id=29267
776 - correctly generate the author key in META.yml
777 http://rt.cpan.org/Ticket/Display.html?id=30377
779 - correctly blend a rotated (or matrix_transformed()) image when
780 performing interpolation in the presence of an alpha channel.
781 Also corrected the centring of the rotated image on the output
784 Imager 0.60 - 30 August 2007
787 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
788 now has full SGI RGB image format, including RLE and 16-bit/sample
790 https://rt.cpan.org/Ticket/Display.html?id=8666
792 - logging functions are now available in the API
794 - applied Gabriel Vasseur's patch
795 added documentation, further tests, and support for greyscale images
796 Obviously problems are my fault :)
797 https://rt.cpan.org/Ticket/Display.html?id=28142
799 - the mask for ICO/CUR images is now applied as an alpha channel to
800 the returned image. For the old behaviour, supply ico_masked => 0
801 to read() or read_multi(). This should be less confusing when
802 using Imager as a general image processor.
803 https://rt.cpan.org/Ticket/Display.html?id=29001
807 - in some cases it's possible for giflib/libungif to return color
808 indexes outside the range of colors defined by the image's palette.
809 We now expand the palette to match the indexes used.
810 Thanks to Gabriel Vasseur for reporting this.
812 - fixed various memory leaks that could occur when failing to read png,
813 jpeg, bmp or tga files.
815 - to avoid confusion, channels not present in the image are returned as
816 zero by getscanline(). This has no effect on the C level i_glin()
817 and i_glinf() API functions which continue to not set the unused
820 - the convert() method now returns an image of the same sample size as
822 https://rt.cpan.org/Ticket/Display.html?id=28492
824 - remove repeated text in Imager::Files
825 http://rt.cpan.org/Ticket/Display.html?id=27589
827 - be even more explicit that scale() and friends don't modify the source
828 image, but return a new image.
829 http://rt.cpan.org/Ticket/Display.html?id=28570
831 - improve the error message from errstr() when you try to load a font
832 for which the driver hasn't been built in Imager.
833 http://rt.cpan.org/Ticket/Display.html?id=27571
835 - transparency is now enabled by default when writing GIF images
836 http://rt.cpan.org/Ticket/Display.html?id=27615
838 - Imager would not load on Windows 98
839 http://rt.cpan.org/Ticket/Display.html?id=27653
841 Imager 0.59 - 14 June 2007
846 - fixes a regression introduced by the fixes for RT 11972
847 http://rt.cpan.org/Ticket/Display.html?id=27546
849 - cropping outside the image would return an Imager object with
850 no low-level image object, instead of returning false.
851 Fixed by: Philip Gwyn (Leolo)
852 http://rt.cpan.org/Ticket/Display.html?id=27509
854 Imager 0.58 - 16 May 2007
857 No significant changes from 0.57_01.
859 Imager 0.57_01 - 11 May 2007
862 - added to_rgb16 to produce a 16-bit/sample version of an image
864 - improve freetype 1.x text output efficiency
868 - search another place for rgb.txt, and check all the places
869 Imager::Color checks when deciding whether to skip testing it
870 http://rt.cpan.org/Ticket/Display.html?id=26064
872 - use a convolution kernel size based on the stddev rather than a
873 fixed size when performing a gaussian blur
874 http://rt.cpan.org/Ticket/Display.html?id=25645
876 - document the difference() method's mindist parameter, and debug it.
878 - put the Imager release number in the Inline::C generated code to
879 regenerate Inline code when a new release of Imager is installed.
880 http://rt.cpan.org/Ticket/Display.html?id=26278
882 - fix rendering on alpha channel images for the FreeType 1.x driver.
883 http://rt.cpan.org/Ticket/Display.html?id=11972
885 - fix rendering on alpha channel images for the T1lib driver.
886 http://rt.cpan.org/Ticket/Display.html?id=11972
888 - reworked library probing, we can now set more than one probe
889 function for a library. Disabled the default (non-freetype-config)
890 library probe and added an extra probe function that searches for
891 both ft2build.h and whatever it includes, and adds -I as needed.
892 Hopefully this will fix build problems like
893 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
894 http://rt.cpan.org/Ticket/Display.html?id=26086
896 Imager 0.57 - 30 Apr 2007
899 This is a maintenence release fixing a security issue in Imager.
901 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
902 overflow in malloced memory. There will be further discussion of
903 this issue in the ticket below.
904 http://rt.cpan.org/Ticket/Display.html?id=26811
905 CVE-2007-2459 CVE-2007-2413
906 The descriptions at cve.mitre.org varied in quality, please see the
907 ticket at rt.cpan.org for a more accurate description of the issue.
909 Imager 0.56 - 1 Apr 2007
912 - added support for reading 16-bit/sample PGM/PPM images
914 - added support for writing 16-bit/sample PGM/PPM images
916 - improved performance of reading PBM/PGM/PPM images
918 - added support for writing PBM images if the image is paletted and
919 contains only black and white
921 - added a new make_colors value - "mono"
923 - switched from the svn log Changes to a manual Changes to reduce
926 - new sample code - samples/flasher.pl
930 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
931 was returning an image object with an extra reference, this
932 resulted in a memory leak.
933 http://rt.cpan.org/Ticket/Display.html?id=24992
935 - fix rendering on alpha channel images for the FreeType 2.x driver
936 http://rt.cpan.org/Ticket/Display.html?id=11972
938 - reading bmp files now consitently handles short reads. You can now
939 supply a parameter to treat a short read as successful and set
941 http://rt.cpan.org/Ticket/Display.html?id=8426
943 - previously, reading ASCII PBM files required spaces between samples,
944 even though the format doesn't require that
946 - improved documentation of the unsharpmask filter (I hope)
947 http://rt.cpan.org/Ticket/Display.html?id=25531
949 - force flushing of the output from i_tt_dump_names() and test output
950 in t/t35ttfont.t to prevent output from being mixed up.
951 https://rt.cpan.org/Ticket/Display.html?id=24859
953 - rewrite a conditional expression as an if() to hopefully work around
954 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
955 https://rt.cpan.org/Ticket/Display.html?id=25561
957 - avoid Data::Dumper in regops.perl to support older releases of perl
958 https://rt.cpan.org/Ticket/Display.html?id=24391
960 Imager 0.55 - 16 Dec 2006
963 This is primarily a bug fix release.
965 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
967 There is one new feature:
969 - the Win32 font driver now supports UTF8 (RT 22166)
970 http://www.cpanforum.com/threads/3276
971 http://rt.cpan.org/Ticket/Display.html?id=22166
973 Several bugs were fixed:
975 - the string() method would not output the string "0"
976 http://rt.cpan.org/Public/Bug/Display.html?id=21770
978 - fills.c was failing to compile on Solaris 10 (compiler unknown)
979 http://rt.cpan.org/Public/Bug/Display.html?id=21944
981 - the gif_disposal and gif_user_input tags weren't being read from
983 http://rt.cpan.org/Public/Bug/Display.html?id=22192
985 - gif.c was failing to build under MSVC
986 http://rt.cpan.org/Ticket/Display.html?id=23922
988 - in some cases strings passed to the string() method were treated as
989 terminated by NUL (chr 0)
990 http://rt.cpan.org/Public/Bug/Display.html?id=21770
992 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
993 that's the default build name for zlib on Win32.
994 http://rt.cpan.org/Ticket/Display.html?id=23064
996 - search $Config{incpath} for headers too, which we should have been
999 Win32 font driver fixes:
1001 - the global descent value from bounding box was the wrong sign
1002 http://www.cpanforum.com/threads/3276
1004 - if the first or last glyph overflowed the left or right side of the
1005 advance width they would be clipped
1008 Imager 0.54 - 14 Sep 2006
1011 This is primarily a feature release:
1013 - a new qtype value 'mixing' has been added to the scale()
1014 method. This is faster than 'normal', slower than 'preview'. This
1015 is based on the method used by pnmscale, and seems to produce less
1016 blurry results than normal.
1017 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1019 - the rubthrough() method can now render onto images with an alpha
1021 http://rt.cpan.org/Ticket/Display.html?id=20678
1023 - the read_multi() method now falls back to calling doing a single
1024 image read via the read() method and write_multi() will now fall
1025 back to calling write() if a single image is supplied. This means
1026 you can simply call the read_multi() or write_multi() functions
1027 without having to check if the type is formatted by that method.
1028 http://rt.cpan.org/Ticket/Display.html?id=19457
1029 http://rt.cpan.org/Ticket/Display.html?id=19458
1031 - the GIF loop extension can now be written. If you don't have
1032 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1034 http://rt.cpan.org/Ticket/Display.html?id=21185
1036 - getscanline() and setscanline() can now read/write palette index
1037 based data from/to the image for paletted images, by setting type to
1039 http://rt.cpan.org/Ticket/Display.html?id=20338
1041 - we no longer hassle you to disable GIF support
1042 http://rt.cpan.org/Ticket/Display.html?id=20687
1044 - minor documentation fixes
1047 Imager 0.53 - 26 Jul 2006
1050 This is a bugfix release.
1052 Some test code was left in a code path not covered by the test
1053 suite. A test was added to cover this code path and the test code was
1055 http://rt.cpan.org/Public/Bug/Display.html?id=20705
1058 Imager 0.52 - 25 Jul 2006
1061 This is primarily a feature release, but contains a fair few bug
1062 fixes, new features:
1064 - ability to read and write MS Windows ICO and CUR files
1066 - you can now add file format plugins to support new file formats
1068 - add POD coverage tests
1070 - setcolors() and addcolors() now accept color names and so on
1071 instead of requiring Imager::Color objects.
1072 http://rt.cpan.org/Ticket/Display.html?id=20056
1074 - flood_fill() can now fill to a specified border color instead of
1075 just to the area the same color as the seed.
1076 http://rt.cpan.org/Ticket/Display.html?id=19618
1081 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1082 calculating the advance width.
1083 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1085 - bounding_box for the T1 driver wasn't including leading and
1086 trailing spaces in the bounding box as the other drivers did, it also
1087 produced strange results for empty strings or strings containing only
1090 - when reading CMYK jpeg images they were being transferred to the
1091 image object as is, producing a four channel image. It only looked ok
1092 due to an old still unfixed Photoshop bug. We now convert from the
1093 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1094 http://rt.cpan.org/Ticket/Display.html?id=20416
1096 - reading a CYMK TIFF would result in a 4 channel image, reading any
1097 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1099 http://rt.cpan.org/Ticket/Display.html?id=20415
1101 - added /usr/local/include to the default include search path, since
1102 we were already searching /usr/local/lib for libraries.
1104 And various minor fixes and documentation updates.
1107 Imager 0.51 - 23 Apr 2006
1110 - fix a validation bug when processing JPEG EXIF data that can cause
1112 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1114 - fix mis-processing of the src_maxx and src_maxy parameters of the
1116 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1118 - fix a problem in Imager's "smart" handling of the color parameter
1120 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1123 Imager 0.50 - 29 Mar 2006
1126 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1127 or 4 channel image to jpeg or a 2 channel image to tga where the
1128 output is an in-memeory buffer.
1129 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1131 - fixes an incorrect pointer parameter in the PNG code
1132 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1134 - skip Inline::C tests when building in a directory with spaces
1135 http://rt.cpan.org/Public/Bug/Display.html?id=18049
