1 Imager release history. Older releases can be found in Changes.old
3 Imager 0.85 - unreleased
8 - the image file limits set by set_file_limits() weren't being
9 checked when reading TIFF files.
10 https://rt.cpan.org/Ticket/Display.html?id=69915
12 - Provide more information about file format module load errors on a
13 failed image file read() or write().
14 https://rt.cpan.org/Ticket/Display.html?id=69194
16 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
17 through TIFF images, since it checks for IFD loops.
18 https://rt.cpan.org/Ticket/Display.html?id=69914
20 - don't leak memory when out of range palette indexes are supplied to
22 https://rt.cpan.org/Ticket/Display.html?id=69242
24 - require a later version of CPAN::Meta to ensure JSON::PP and
25 CPAN::Meta::YAML are available.
26 https://rt.cpan.org/Ticket/Display.html?id=69008
28 - hoist the per-line calculations for the flines implementations, and
29 modernize the tests a bit.
30 https://rt.cpan.org/Ticket/Display.html?id=70126
32 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
34 https://rt.cpan.org/Ticket/Display.html?id=69147
36 - if t1lib failed to reinitialize it would be left as marked
38 https://rt.cpan.org/Ticket/Display.html?id=69877
40 Imager 0.84_01 - 8 Aug 2011
43 Development release as a sanity check for the types re-work.
45 Massive types re-work:
47 - the type used internally for pixel co-ordinates and image sizes is
48 now 64-bit on 64-bit platforms (at least sane ones).
50 - size_t is now used consistently for memory block sizes.
52 - since this changes the binary interface, the Imager API version has
53 been incremented. Any module that uses the API will need to be
54 rebuilt. In most cases that will be enough, but calls to any APIs
55 that take a pointer to image sizes may need source changes.
57 - you should be able to create very large images on 64-bit systems,
58 if you have enough memory. Successfully created a 32768 x 49192 x
59 3 channel image, filled with a tiled image and scaled it. The
60 unscaled image was also successfully saved to a JPEG.
62 - check the image size before attempting to write BMP, GIF, JPEG,
63 PNG, SGI, TGA, TIFF images.
65 - correctly handle reading TGA images over 32767 pixels wide or tall.
69 - the gif_left and gif_top tags are now clamped to non-negative
70 values when writing a GIF image.
72 - removed dead callback read/write code
74 The default maximum memory size when reading files is now 1G.
76 Imager 0.84 - 20 Jun 2011
79 - Imager no longer inherits from Exporter (unless you're running an
82 - Imager can now write progressive JPEGs (it could always read them).
83 https://rt.cpan.org/Ticket/Display.html?id=68691
87 - re-work, document and test Imager's logging facility.
88 https://rt.cpan.org/Ticket/Display.html?id=65227
90 - fix META.yml testing and the generated META.yml
91 https://rt.cpan.org/Ticket/Display.html?id=65235
93 - test and add error reporting to to_*() family methods
95 - add to_rgb_double() method.
96 https://rt.cpan.org/Ticket/Display.html?id=65101
98 - Imager no longer exports anything by default
99 https://rt.cpan.org/Ticket/Display.html?id=65228
101 - convert colors to grayscale if the supplied (or generated) palette
102 contains only grays when performing error diffusion color
104 https://rt.cpan.org/Ticket/Display.html?id=68508
106 - writing a paletted image to GIF wouldn't always use the colors
107 supplied (or generated, eg. via make_colors => "mono"), which was
109 https://rt.cpan.org/Ticket/Display.html?id=67912
111 - replace (imager|tony)@imager.perl.org in the doc, since I don't
112 plan to continue receiving mail at that address.
113 https://rt.cpan.org/Ticket/Display.html?id=68591
115 Imager 0.83 - 21 May 2011
120 - diag() the error message on failure for some TIFF tests that are
121 failing on a Solaris smoker.
122 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
124 Imager 0.82_01 - 17 May 2011
127 Dev release, in case the compose tests are too sensitive.
131 - Imager::Font::T1 incorrectly checked for absolute filename under
132 Win32. Thanks to kmx for the report and fix.
133 https://rt.cpan.org/Ticket/Display.html?id=67963
135 - compose() with the target, source or mask position off the top or
136 left of the target image didn't clip the source image correctly.
137 https://rt.cpan.org/Ticket/Display.html?id=67220
139 - compose() now returns a useful error message on a non-positive
142 - compose.im now at 100% test coverage. (As opposed to, umm, much,
145 Imager 0.82 - 14 Mar 2011
150 - eliminate calls to i_has_format() from the test suite, since it's
151 no longer a useful way to check for file format support. Eliminate
152 i_has_format() from the functions exposed via XS.
153 https://rt.cpan.org/Ticket/Display.html?id=65863
155 - eliminate calls to note(), which isn't in the (very old) version of
156 Test::More we have as a pre-requisite. note() is modern enough
157 that I don't feel a need to require a Test::More upgrade for it.
158 https://rt.cpan.org/Ticket/Display.html?id=65864
160 - skip the threads tests on Test::More 2.00_*
161 https://rt.cpan.org/Ticket/Display.html?id=65812
163 - add an (unshipped) test to check Imager's internal POD links
164 https://rt.cpan.org/Ticket/Display.html?id=65749
166 - improve the library detection summary
167 https://rt.cpan.org/Ticket/Display.html?id=9675
169 - increase the version of Imager::Font::Type1 so that upgrades don't
170 downgrade the version in this file.
171 https://rt.cpan.org/Ticket/Display.html?id=66250
173 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
174 that option for the directories that would normally go in
175 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
176 https://rt.cpan.org/Ticket/Display.html?id=65955
178 Imager 0.81 - 14 Feb 2011
181 - added coverage tests for masked images (maskimg.c @100% test coverage)
183 - add hsv() method to Imager::Color
184 Thanks to Leolo (Philip Gwyn)
185 https://rt.cpan.org/Ticket/Display.html?id=65385
187 - split libt1 Type 1 font support into a sub-module
188 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
190 - add a preload() class method for use in forking servers, and to
191 work around limitations in PAR.
192 https://rt.cpan.org/Ticket/Display.html?id=65665
196 - paletted writes to a masked image are now masked correctly.
197 Revealed by new coverage tests.
199 - update the filter plugin documentation.
200 https://rt.cpan.org/Ticket/Display.html?id=56513
202 - add the matrix() method to Imager::Matrix2d to allow creation of a
203 matrix with specified co-efficients. You can now multiple an
204 Imager::Matrix2d object by a 9 element array ref or a number.
205 https://rt.cpan.org/Ticket/Display.html?id=29938
207 - really fix loading TTF fonts with FT2 when FT1 isn't available.
208 Thanks to Leolo (Philip Gwyn)
209 https://rt.cpan.org/Ticket/Display.html?id=65386
210 https://rt.cpan.org/Ticket/Display.html?id=62855
212 - make sure each test script that needs testout/ creates it.
213 https://rt.cpan.org/Ticket/Display.html?id=65088
215 - handle a slightly different warning from libtiff 4.x
216 https://rt.cpan.org/Ticket/Display.html?id=65268
218 - the sat transform2() op returned an incorrect saturation.
219 https://rt.cpan.org/Ticket/Display.html?id=65391
221 Imager 0.80 - 17 Jan 2011
224 - added coverage tests for Imager::Fountain and Imager::Color::Float
226 - Imager is now maintained in git
227 http://git.imager.perl.org/imager.git
228 git://git.imager.perl.org/imager.git
232 - images with an translucent alpha channel were not scaled correctly
233 by the default (qtype=normal) scaling method.
234 https://rt.cpan.org/Public/Bug/Display.html?id=63922
236 - Imager::Color::Float now translates "#FFFFFF" to white instead of
237 just a little darker.
239 - make the default color map build algorithm "mediancut". This
240 changes the default color map builder for writing GIFs back to what
241 it was in 0.77, reverting a performance regression.
242 https://rt.cpan.org/Ticket/Display.html?id=64785
244 - handle failure to create a masked image correctly
246 Imager 0.79 - 10 Dec 2010
249 - add Imager::Test to the POD coverage tests and document the missing
252 - the convert() method now optimizes the case where all output
253 channels are either 0, sourced from a single input channel or 1.
254 This significantly speeds up presets like "addalpha", "green".
255 https://rt.cpan.org/Ticket/Display.html?id=51254
257 - add wiggle.pl sample, as suggested by Dan Oppenheim.
259 - add the combine() method to combine channels from multiple source
260 images into a new image
261 https://rt.cpan.org/Ticket/Display.html?id=11872
265 - treat the co-efficients for convert() as doubles instead of floats.
267 - If a higher (earlier) priority font handler failed to load, that
268 would crash preventing loading of later font handlers.
269 https://rt.cpan.org/Ticket/Display.html?id=62855
271 - parse defines from the options returned by pkg-config --cflags
272 https://rt.cpan.org/Ticket/Display.html?id=63223
274 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
275 included in the tarball. They are now included.
277 Imager 0.78 - 4 Oct 2010
282 - don't access deprecated members of the png_structp.
283 https://rt.cpan.org/Ticket/Display.html?id=60242
285 - document that using color objects is faster than supplying colors
287 https://rt.cpan.org/Ticket/Display.html?id=61047
289 - Imager::Probe now accepts array references for incpath and libpath.
290 https://rt.cpan.org/Ticket/Display.html?id=60244
292 Imager 0.77_02 - 27 Sep 2010
295 - moved Win32, FreeType 2 font support into sub-modules.
296 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
297 Uses Imager::Probe now.
298 https://rt.cpan.org/Public/Bug/Display.html?id=61328
300 - tested successfully with jpeg-8b
301 https://rt.cpan.org/Ticket/Display.html?id=60221
305 - from _01: look for missing file support test files in the right
308 - flood_fill() wouldn't fill the right side of a single scan-line
310 Thanks to Nicolas Roggli for reporting this.
312 - flood_fill wouldn't fill to the left edge of the image if the
313 starting line didn't reach the left edge.
314 Thanks to Nicolas Roggli for reporting this.
316 Imager 0.77_01 - 13 Sep 2010
319 - add each library-directory/pkgconfig/ to the pkg-config search path
321 Thanks to Justin Davis.
322 https://rt.cpan.org/Ticket/Display.html?id=60491
324 - moved GIF, TIFF, JPEG file handling code into sub-modules in
325 preparation for separate distribution.
326 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
328 - optimize filled box drawing (color, not fill)
332 - Imager::Probe was calling ExtUtils::Liblist to initialize
333 LD_RUN_PATH supplying an undefined value rather than the found
334 directory. Thanks to Justin Davis.
335 https://rt.cpan.org/Ticket/Display.html?id=60491
337 - only prepend ./ to font filenames when passing them to T1Lib and
338 then only when it would use its search mechanisms.
339 https://rt.cpan.org/Ticket/Display.html?id=60509
341 - fix the cache check for the X rgb.txt loader. This is typically
342 used for color translation on Unix-like systems, and the fix
343 improves performance of supplying colors by name by about 80 times.
344 Test code that managed 3400 10x10 pixel boxes/second sped up to
347 - clarify that Imager doesn't write EXIF metadata to images.
348 https://rt.cpan.org/Ticket/Display.html?id=60637
350 - Imager::Probe can now search subdirectories under its include path.
351 Used by the PNG Makefile.PL to find headers and libraries when they
352 aren't in the base directory, as in cygwin.
353 https://rt.cpan.org/Ticket/Display.html?id=60635
355 Imager 0.77 - 11 Aug 2010
358 I don't want Imager::File::PNG indexed as part of Imager, but forgot
359 to update the META.yml before updating the version.
361 - don't index Imager::File::PNG as part of Imager
363 - add resources to META.yml
365 Imager 0.76 - not released
370 - the align_string() method would ignore a string of "0" due to a
372 Thanks to Maurice Height for reporting this.
373 https://rt.cpan.org/Ticket/Display.html?id=60199
375 Imager 0.75_03 - 09 Aug 2010
380 - read_types() and write_types() would include png when it wasn't
381 available due to a problem with the %formats tie
383 - handle dependent libraries correctly (eg -lpng requiring -lz) in
384 the code run phase of library probing.
386 Imager 0.75_02 - 07 Aug 2010
391 - add file missing from MANIFEST, which was causing TIFF failures.
393 Imager 0.75_01 - 06 Aug 2010
396 Test release for the new PNG probe.
398 - added the ability to read multiple-image PNM files.
399 Note that unlike the pbm/pgm/ppm specification this accepts mixed
400 format files and allows white space padding between files.
401 Thanks to Philip Gwyn (Leolo) for this patch.
403 - moved the PNG file handling code into a sub-module in preparation
404 for separate distribution.
405 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
406 Also helps avoid complications from -I/-L compile/link options from
411 - Imager->new(data => $data) didn't try to process image file data in
413 https://rt.cpan.org/Ticket/Display.html?id=58761
415 - t/t50basicoo.t no longer depends on the other tests to generate its
417 https://rt.cpan.org/Ticket/Display.html?id=9798
418 Also, it wasn't testing pnm (pnm vs ppm mix-up)
420 - update the documentation of hardinvert to match the change in 0.62.
421 https://rt.cpan.org/Ticket/Display.html?id=59785
423 - added hardinvertall filter which also inverts the alpha channel
426 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
427 the probe can find the library for the test run.
428 https://rt.cpan.org/Ticket/Display.html?id=57518
430 Imager 0.75 - 20 Jun 2010
433 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
438 - an opacity fill based on a fountain fill would segfault when
439 filling an 8-bit/sample image.
441 - merge thickline branch polygon fix
442 https://rt.cpan.org/Ticket/Display.html?id=43518
444 Imager 0.74 - 7 May 2010
449 - read_multi() didn't handle a missing file format library correctly,
450 aborting on failing to call i_readgif_multi_wiol() or
451 i_readtiff_multi_wiol().
453 - fix spelling errors patched by Debian
454 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
456 - add an (unshipped) author test to spellcheck Imager's POD.
458 - update the TIFF file format documentation
459 https://rt.cpan.org/Ticket/Display.html?id=56510
461 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
463 Imager 0.73 - 15 Mar 2010
466 - implement outline circles, both anti-aliased and not
467 https://rt.cpan.org/Ticket/Display.html?id=19755
469 - a combine => "none" fill to a 1 or 3 channel image would produce
470 the incorrect colour.
472 Imager 0.72 - 09 Dec 2009
475 Bump version for release, since 0.71_03 is stable with CPAN testers.
477 Imager 0.71_03 - 5 Dec 2009
480 - further adjust the threads test so it only performs the tests on
481 perls where it's expected to work, and only if the threads module
484 Imager 0.71_02 - 1 Dec 2009
487 - adjust the way we load the threads module for the threads test so
488 it works with non-threaded perls
490 Imager 0.71_01 - 30 Nov 2009
495 - use scanline oriented operations to flip images instead of pixel
497 https://rt.cpan.org/Ticket/Display.html?id=39278
499 - use double/sample operations to flip large sample images instead of
500 8-bit sample operations.
501 https://rt.cpan.org/Ticket/Display.html?id=39280
504 https://rt.cpan.org/Ticket/Display.html?id=51874
506 - prevent double-frees when someone creates Imager objects and then
507 creates a thread. Note: this just handles some simple cases,
508 Imager doesn't support perl threads, and isn't likely to.
509 https://rt.cpan.org/Ticket/Display.html?id=52268
511 Imager 0.71 - 16 Nov 2009
514 - add the opacity fill type - an adaptor that modifies the opacity of
519 - the conv filter now enforces that the sum of the coefficients is
520 non-zero. Also, rather than skipping pixels off the edge off the
521 edge of the image, the closest edge pixel is used. Previously
522 dividing by the zero sum of coefficients could cause invalid
523 results or runtime exceptions.
524 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
527 Imager 0.70 - 21 Sep 2009
532 - release image row and comments memory on all error returns in gif
535 - handle zero length extensions, previously this would cause a null
537 Thanks to Krzysztof Wojtaś for the test data and fix for this.
539 - an integer division meant that preview scaling to below 1 pixel
540 wide or high (which isn't too useful anyway) was calculating using
541 NaNs on most platforms, and causing an exception on others.
542 Thanks to David Cantrell for producing a backtrace of the crash on
543 his Alpha-NetBSD CPAN test box which made it possible to track this
546 Imager 0.69 - 08 Sep 2009
551 - broken test fix - was attempting to call a function skip_all, when
552 that should be a parameter to plan().
554 - briefly document apidocs.perl, the tool used to build
555 Imager::APIRef and make some minor enhancements
557 - various minor documentation enhancements and fixes.
559 Imager 0.68 - 07 Sep 2009
562 - Imager->new(file => $filename) and other similar incantations will
564 https://rt.cpan.org/Ticket/Display.html?id=48261
568 - avoid using CHECK as a label in Imager::Test
569 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
571 - re-work most image file test files that require a library into
572 separate library present/not present files to remove stupidly long
575 - don't treat rubthrough() outside the bounds of the target image as
577 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
579 Imager 0.67_01 - 02 Sep 2009
584 - correct documentation of default of raw image interleave read
586 https://rt.cpan.org/Ticket/Display.html?id=42074
588 - add raw_ prefix to raw read parameters, though the original names
591 - fail the read if an invalid raw_interleave parameter is supplied
593 - warn if no interleave or raw_interleave parameter is supplied,
594 since the documented default was wrong, and incompatible with the
597 - for reading raw images, if raw_storechannels > raw_datachannels,
598 set the extra channels in the image to 0
600 - when probing for executables like freetype-config, search for .bat
601 and .cmd on MSWin32, as well as .exe.
602 https://rt.cpan.org/Ticket/Display.html?id=49275
604 - re-work the external libraries section of README:
605 - list Debian and Redhat package names for each library
609 - use the new EU::MM META_MERGE facility instead of generating
610 META.yml from scratch
611 https://rt.cpan.org/Ticket/Display.html?id=47888
613 - use Devel::CheckLib (bundled, modified) to check which release of
614 libtiff is installed and reject 3.9.0
615 http://bugzilla.maptools.org/show_bug.cgi?id=2088
616 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
618 Imager 0.67 - 12 Dec 2008
623 - fix a packaging error
625 Imager 0.66 - 12 Dec 2008
628 - 24-bit color .ICO/.CUR files can now be read.
632 - an optimization skipping 0 src alpha values could cause the
633 rubthrough() to read past the end of a buffer.
634 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
636 - corrected a reference leak where writing GIFs would leak memory.
637 This could also happen calling to_paletted().
638 Also documented the underlying long existing feature where the
639 colors parameter is filled with the generated color table and added
641 http://rt.cpan.org/Ticket/Display.html?id=41028
643 - write out the image size in bytes field of a BMP correctly.
644 http://rt.cpan.org/Ticket/Display.html?id=41406
646 - add limited tests for Imager::ExtUtils
648 - make Imager::ExtUtils->includes use an absolute path, since
649 a relative path could cause failures using Inline::C.
650 http://rt.cpan.org/Ticket/Display.html?id=37353
652 - re-arrange the POD for Imager::Font::BBox:
653 - mark total_width(), pos_width(), end_offset() obsolete, since
654 they're mostly for backwards compatibility
655 - group width methods and height methods
656 https://rt.cpan.org/Ticket/Display.html?id=39999
658 Imager 0.65 - 20 May 2008
663 - In some cases when an error occurs reading those parts of a JPEG
664 file after the image the scan-line buffer could be freed a second
665 time. In cases where the the error occured while reading the image
666 data it's possible that the buffer could have leaked.
667 Thanks to Gabriel Vasseur for reporting this and help in tracking
670 - the gif_screen_height tag was overriding the screen width and being
671 ignored for the screen height when present.
672 https://rt.cpan.org/Public/Bug/Display.html?id=35568
674 Imager 0.64 - 23 April 2008
677 This is a bug fix release. This includes a fix for a possible
682 - Possible security issue: The floating point sample path for image
683 based fills had a buffer overflow. This would overwrite the end of
684 a malloc()ed buffer with double precision floats.
685 http://rt.cpan.org/Ticket/Display.html?id=35324
688 - check that the result of fileno($fh) is defined rather than simply
689 true when read() or write() is supplied with an fh parameter.
690 http://rt.cpan.org/Ticket/Display.html?id=35139
692 - i_scale_axis() wasn't checking the result of i_img_new_ch()
693 resulting in a SIGSEGV when attempting to scale an image to a size
694 too large to fit in memory. This is a NULL pointer access issue,
695 not a buffer overflow.
696 Added a check for the failure.
697 scale_calculate() (and hence scale()) will now fail if any of the
698 scale size parameters are a reference.
699 http://rt.cpan.org/Ticket/Display.html?id=35172
701 - Regression: filling a greyscale image with a hatch used the wrong
702 color channels from the supplied fg/bg colors.
703 https://rt.cpan.org/Ticket/Display.html?id=35278
705 - fixed a related problem for image fills.
707 Imager 0.63 - 7 April 2008
710 This release primarily contains changes to improve ease of use -
711 rather than you having to convert images to the appropriate number of
712 channels, Imager handles it internally. How to handle drawing colors
713 and the default combine mode is a thornier problem left for some other
716 - the font libraries are now only initialized when needed.
717 http://rt.cpan.org/Ticket/Display.html?id=28825
719 - moved the imtoc.perl code into Imager::Preprocess
721 - paste() and rubthrough() now adapt the source image data to the
722 destination, so you can now safely paste/rubthrough from greyscale
723 images to color images or back, or from alpha channel images to
724 noalpha channels or back.
725 https://rt.cpan.org/Ticket/Display.html?id=30908
727 - rubthrough() now falls back to pasting when the source doesn't have
728 an alpha channel. This effectively treats the source as having a
729 max alpha channel, the right thing to do.
730 http://rt.cpan.org/Ticket/Display.html?id=29944
732 - re-worked most of the area filling code to use a common set of
733 functions when filling.
734 Corrected normal combine mode.
735 Rewrote most of the combine modes to match the way the SVG draft
736 defines them with respect to a translucent source and destination.
737 Added tests for translucent source and destination.
738 Added tests to check 8-bit/sample and double/sample combines work
740 https://rt.cpan.org/Ticket/Display.html?id=29879
742 - writing a 2 or 4 channel image to a JPEG file will now write that
743 image as if composited against a background, black by default,
744 overridable with the i_background tag/parameter.
745 https://rt.cpan.org/Ticket/Display.html?id=29876
747 - writing a 2 or 4 channel image to a PGM/PPM file will now write
748 that image as if composited against a background, black by default,
749 overridable with the i_background tag/parameter.
750 http://rt.cpan.org/Ticket/Display.html?id=30074
752 - writing a 2 or 4 channel image to a BMP file will now write that
753 image as if composited against a background, black by default,
754 overridable with the i_background tag/parameter.
755 http://rt.cpan.org/Ticket/Display.html?id=30075
759 - Imager::Matrix2d->translate() now only requires one of the x or y
761 http://rt.cpan.org/Ticket/Display.html?id=29937
763 - mixing qtype scaling now sets all channels of a pixel to zero if
764 the pixel has zero coverage (zero alpha). This should produce more
765 compressible output files.
766 http://rt.cpan.org/Ticket/Display.html?id=32324
768 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
770 https://bugzilla.redhat.com/show_bug.cgi?id=166254
771 I'm not changing the #! lines of the sample code, since it's sample
772 code, not intended for installation.
773 http://rt.cpan.org/Ticket/Display.html?id=33408
775 - some TGA images weren't being detected correctly as TGA images
776 https://rt.cpan.org/Ticket/Display.html?id=32925
778 - handling of the left-over bit for 16-bit/pixel TGA images has been
779 changed to match the behaviour of the GIMP. Previously the bit
780 being set was treated as an opaque pixel, but one user reported a
781 problem with loading such an image. I haven't been able to find any
782 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
783 I'll match it's behaviour. See issue 114913 in the GIMP's
785 http://rt.cpan.org/Ticket/Display.html?id=32926
787 Imager 0.62 - 10 December 2007
790 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
791 to /path under your home directory.
792 http://rt.cpan.org/Ticket/Display.html?id=29484
794 - the old dynaload code used Mach API functions to load dynamic
795 libraries on Mac OS X. These APIs have been deprecated in OS X
796 10.5 and were causing some build problems.
797 So henceforth Imager uses the dlopen() family of functions, and you
798 will need version 10.3 or later of OS X.
800 - added the det() function to the transform2() engine.
801 added the sample quad_to_square.pl
802 Courtesy Richard Fairhurst.
803 http://rt.cpan.org/Ticket/Display.html?id=31244
807 - samples/gifscale.pl sourced the base value for gif_top from
809 Thanks to Eleneldil G. Arilou for pointing this out.
811 - t/t82inline.t no longer loads B at runtime, to work around a bug
812 in some 5.005_0[45] installations.
813 http://rt.cpan.org/Ticket/Display.html?id=30508
815 - work around Module::Depends::Intrusive bug #21229
816 http://rt.cpan.org/Ticket/Display.html?id=30520
818 - the hardinvert filter no-longer inverts the alpha channel.
819 http://rt.cpan.org/Ticket/Display.html?id=30002
821 - the hardinvert filter now supports large samples
823 Imager 0.61_02 - 28 November 2007
826 - major TIFF support re-work
827 http://rt.cpan.org/Ticket/Display.html?id=20329
829 - added a C level image interface for accessing samples from 1-32
830 bits, exposed this at the perl level in getsamples()
832 - the conv filter now works at floating point precision for high bit
835 - added is_bilevel method to test whether an image should be written as
836 a bilevel image if the image format supports it.
838 - added -log-stderr as an Imager import list option
840 - added some important types to Imager::APIRef
842 - added test_image_double() to Imager::Test
846 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
849 - the scale() method with qtype mixing now handles images with an
850 alpha channel correctly.
852 - fixed a broken link from the "animated GIF" entry in the concept index.
853 Thanks to Slaven Rezic.
854 http://rt.cpan.org/Ticket/Display.html?id=30889
856 - on some perl's the infix expression parser test would fail due to
857 actions in the grammar returning false. Made sure all actions return
859 Thanks to Richard Fairhurst for spending a lot of time in tracking
861 http://rt.cpan.org/Public/Bug/Display.html?id=29562
863 Imager 0.61 - 5 November 2007
866 - added samples/gifscale.pl, which adjusts the screen size/position tags
867 when scaling an animated gif
868 http://rt.cpan.org/Ticket/Display.html?id=27591
872 - correct handling of sz in matrix_transform() - this should allow
873 perspective type transformations to work now.
874 http://rt.cpan.org/Ticket/Display.html?id=29936
876 - prevent a cast to integer warning on x64 builds in datatypes.c
877 also fixed some other type warnings
878 https://rt.cpan.org/Ticket/Display.html?id=30204
880 - some sub-directory tests depended on files produced by the parent
882 http://rt.cpan.org/Ticket/Display.html?id=30203
884 - Imager::Font::Wrap doesn't correctly set savepos
885 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
886 http://rt.cpan.org/Ticket/Display.html?id=29771
888 - test 171 in t/t01introvert.t was failing on perls configured to
890 http://rt.cpan.org/Ticket/Display.html?id=29413
892 - the code for the transform2() uminus operator was missing a break.
893 Added tests for better code coverage of the ops.
894 http://rt.cpan.org/Ticket/Display.html?id=29296
896 - the SGI RLE compression code could overflow its compression buffer
897 http://rt.cpan.org/Ticket/Display.html?id=30334
899 - the 32-bit output function used by the SGI code only handled values
900 under 0x10000. This was most noticable when writing large RLE images.
901 http://rt.cpan.org/Ticket/Display.html?id=30335
903 - validate chan_count for chans == NULL for each of the i_gsamp()
905 http://rt.cpan.org/Ticket/Display.html?id=28985
907 - attempt to work around the test failure at
908 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
909 http://rt.cpan.org/Ticket/Display.html?id=29562
911 - improve the error messages produced when attempting to read or write
912 an unknown image file format.
913 http://rt.cpan.org/Ticket/Display.html?id=30103
915 - improve the transform2() documentation
916 http://rt.cpan.org/Ticket/Display.html?id=29267
918 - correctly generate the author key in META.yml
919 http://rt.cpan.org/Ticket/Display.html?id=30377
921 - correctly blend a rotated (or matrix_transformed()) image when
922 performing interpolation in the presence of an alpha channel.
923 Also corrected the centring of the rotated image on the output
926 Imager 0.60 - 30 August 2007
929 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
930 now has full SGI RGB image format, including RLE and 16-bit/sample
932 https://rt.cpan.org/Ticket/Display.html?id=8666
934 - logging functions are now available in the API
936 - applied Gabriel Vasseur's patch
937 added documentation, further tests, and support for greyscale images
938 Obviously problems are my fault :)
939 https://rt.cpan.org/Ticket/Display.html?id=28142
941 - the mask for ICO/CUR images is now applied as an alpha channel to
942 the returned image. For the old behaviour, supply ico_masked => 0
943 to read() or read_multi(). This should be less confusing when
944 using Imager as a general image processor.
945 https://rt.cpan.org/Ticket/Display.html?id=29001
949 - in some cases it's possible for giflib/libungif to return color
950 indexes outside the range of colors defined by the image's palette.
951 We now expand the palette to match the indexes used.
952 Thanks to Gabriel Vasseur for reporting this.
954 - fixed various memory leaks that could occur when failing to read png,
955 jpeg, bmp or tga files.
957 - to avoid confusion, channels not present in the image are returned as
958 zero by getscanline(). This has no effect on the C level i_glin()
959 and i_glinf() API functions which continue to not set the unused
962 - the convert() method now returns an image of the same sample size as
964 https://rt.cpan.org/Ticket/Display.html?id=28492
966 - remove repeated text in Imager::Files
967 http://rt.cpan.org/Ticket/Display.html?id=27589
969 - be even more explicit that scale() and friends don't modify the source
970 image, but return a new image.
971 http://rt.cpan.org/Ticket/Display.html?id=28570
973 - improve the error message from errstr() when you try to load a font
974 for which the driver hasn't been built in Imager.
975 http://rt.cpan.org/Ticket/Display.html?id=27571
977 - transparency is now enabled by default when writing GIF images
978 http://rt.cpan.org/Ticket/Display.html?id=27615
980 - Imager would not load on Windows 98
981 http://rt.cpan.org/Ticket/Display.html?id=27653
983 Imager 0.59 - 14 June 2007
988 - fixes a regression introduced by the fixes for RT 11972
989 http://rt.cpan.org/Ticket/Display.html?id=27546
991 - cropping outside the image would return an Imager object with
992 no low-level image object, instead of returning false.
993 Fixed by: Philip Gwyn (Leolo)
994 http://rt.cpan.org/Ticket/Display.html?id=27509
996 Imager 0.58 - 16 May 2007
999 No significant changes from 0.57_01.
1001 Imager 0.57_01 - 11 May 2007
1004 - added to_rgb16 to produce a 16-bit/sample version of an image
1006 - improve freetype 1.x text output efficiency
1010 - search another place for rgb.txt, and check all the places
1011 Imager::Color checks when deciding whether to skip testing it
1012 http://rt.cpan.org/Ticket/Display.html?id=26064
1014 - use a convolution kernel size based on the stddev rather than a
1015 fixed size when performing a gaussian blur
1016 http://rt.cpan.org/Ticket/Display.html?id=25645
1018 - document the difference() method's mindist parameter, and debug it.
1020 - put the Imager release number in the Inline::C generated code to
1021 regenerate Inline code when a new release of Imager is installed.
1022 http://rt.cpan.org/Ticket/Display.html?id=26278
1024 - fix rendering on alpha channel images for the FreeType 1.x driver.
1025 http://rt.cpan.org/Ticket/Display.html?id=11972
1027 - fix rendering on alpha channel images for the T1lib driver.
1028 http://rt.cpan.org/Ticket/Display.html?id=11972
1030 - reworked library probing, we can now set more than one probe
1031 function for a library. Disabled the default (non-freetype-config)
1032 library probe and added an extra probe function that searches for
1033 both ft2build.h and whatever it includes, and adds -I as needed.
1034 Hopefully this will fix build problems like
1035 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
1036 http://rt.cpan.org/Ticket/Display.html?id=26086
1038 Imager 0.57 - 30 Apr 2007
1041 This is a maintenence release fixing a security issue in Imager.
1043 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
1044 overflow in malloced memory. There will be further discussion of
1045 this issue in the ticket below.
1046 http://rt.cpan.org/Ticket/Display.html?id=26811
1047 CVE-2007-2459 CVE-2007-2413
1048 The descriptions at cve.mitre.org varied in quality, please see the
1049 ticket at rt.cpan.org for a more accurate description of the issue.
1051 Imager 0.56 - 1 Apr 2007
1054 - added support for reading 16-bit/sample PGM/PPM images
1056 - added support for writing 16-bit/sample PGM/PPM images
1058 - improved performance of reading PBM/PGM/PPM images
1060 - added support for writing PBM images if the image is paletted and
1061 contains only black and white
1063 - added a new make_colors value - "mono"
1065 - switched from the svn log Changes to a manual Changes to reduce
1068 - new sample code - samples/flasher.pl
1072 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
1073 was returning an image object with an extra reference, this
1074 resulted in a memory leak.
1075 http://rt.cpan.org/Ticket/Display.html?id=24992
1077 - fix rendering on alpha channel images for the FreeType 2.x driver
1078 http://rt.cpan.org/Ticket/Display.html?id=11972
1080 - reading bmp files now consitently handles short reads. You can now
1081 supply a parameter to treat a short read as successful and set
1083 http://rt.cpan.org/Ticket/Display.html?id=8426
1085 - previously, reading ASCII PBM files required spaces between samples,
1086 even though the format doesn't require that
1088 - improved documentation of the unsharpmask filter (I hope)
1089 http://rt.cpan.org/Ticket/Display.html?id=25531
1091 - force flushing of the output from i_tt_dump_names() and test output
1092 in t/t35ttfont.t to prevent output from being mixed up.
1093 https://rt.cpan.org/Ticket/Display.html?id=24859
1095 - rewrite a conditional expression as an if() to hopefully work around
1096 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
1097 https://rt.cpan.org/Ticket/Display.html?id=25561
1099 - avoid Data::Dumper in regops.perl to support older releases of perl
1100 https://rt.cpan.org/Ticket/Display.html?id=24391
1102 Imager 0.55 - 16 Dec 2006
1105 This is primarily a bug fix release.
1107 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1109 There is one new feature:
1111 - the Win32 font driver now supports UTF8 (RT 22166)
1112 http://www.cpanforum.com/threads/3276
1113 http://rt.cpan.org/Ticket/Display.html?id=22166
1115 Several bugs were fixed:
1117 - the string() method would not output the string "0"
1118 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1120 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1121 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1123 - the gif_disposal and gif_user_input tags weren't being read from
1125 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1127 - gif.c was failing to build under MSVC
1128 http://rt.cpan.org/Ticket/Display.html?id=23922
1130 - in some cases strings passed to the string() method were treated as
1131 terminated by NUL (chr 0)
1132 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1134 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1135 that's the default build name for zlib on Win32.
1136 http://rt.cpan.org/Ticket/Display.html?id=23064
1138 - search $Config{incpath} for headers too, which we should have been
1141 Win32 font driver fixes:
1143 - the global descent value from bounding box was the wrong sign
1144 http://www.cpanforum.com/threads/3276
1146 - if the first or last glyph overflowed the left or right side of the
1147 advance width they would be clipped
1150 Imager 0.54 - 14 Sep 2006
1153 This is primarily a feature release:
1155 - a new qtype value 'mixing' has been added to the scale()
1156 method. This is faster than 'normal', slower than 'preview'. This
1157 is based on the method used by pnmscale, and seems to produce less
1158 blurry results than normal.
1159 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1161 - the rubthrough() method can now render onto images with an alpha
1163 http://rt.cpan.org/Ticket/Display.html?id=20678
1165 - the read_multi() method now falls back to calling doing a single
1166 image read via the read() method and write_multi() will now fall
1167 back to calling write() if a single image is supplied. This means
1168 you can simply call the read_multi() or write_multi() functions
1169 without having to check if the type is formatted by that method.
1170 http://rt.cpan.org/Ticket/Display.html?id=19457
1171 http://rt.cpan.org/Ticket/Display.html?id=19458
1173 - the GIF loop extension can now be written. If you don't have
1174 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1176 http://rt.cpan.org/Ticket/Display.html?id=21185
1178 - getscanline() and setscanline() can now read/write palette index
1179 based data from/to the image for paletted images, by setting type to
1181 http://rt.cpan.org/Ticket/Display.html?id=20338
1183 - we no longer hassle you to disable GIF support
1184 http://rt.cpan.org/Ticket/Display.html?id=20687
1186 - minor documentation fixes
1189 Imager 0.53 - 26 Jul 2006
1192 This is a bugfix release.
1194 Some test code was left in a code path not covered by the test
1195 suite. A test was added to cover this code path and the test code was
1197 http://rt.cpan.org/Public/Bug/Display.html?id=20705
1200 Imager 0.52 - 25 Jul 2006
1203 This is primarily a feature release, but contains a fair few bug
1204 fixes, new features:
1206 - ability to read and write MS Windows ICO and CUR files
1208 - you can now add file format plugins to support new file formats
1210 - add POD coverage tests
1212 - setcolors() and addcolors() now accept color names and so on
1213 instead of requiring Imager::Color objects.
1214 http://rt.cpan.org/Ticket/Display.html?id=20056
1216 - flood_fill() can now fill to a specified border color instead of
1217 just to the area the same color as the seed.
1218 http://rt.cpan.org/Ticket/Display.html?id=19618
1223 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1224 calculating the advance width.
1225 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1227 - bounding_box for the T1 driver wasn't including leading and
1228 trailing spaces in the bounding box as the other drivers did, it also
1229 produced strange results for empty strings or strings containing only
1232 - when reading CMYK jpeg images they were being transferred to the
1233 image object as is, producing a four channel image. It only looked ok
1234 due to an old still unfixed Photoshop bug. We now convert from the
1235 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1236 http://rt.cpan.org/Ticket/Display.html?id=20416
1238 - reading a CYMK TIFF would result in a 4 channel image, reading any
1239 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1241 http://rt.cpan.org/Ticket/Display.html?id=20415
1243 - added /usr/local/include to the default include search path, since
1244 we were already searching /usr/local/lib for libraries.
1246 And various minor fixes and documentation updates.
1249 Imager 0.51 - 23 Apr 2006
1252 - fix a validation bug when processing JPEG EXIF data that can cause
1254 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1256 - fix mis-processing of the src_maxx and src_maxy parameters of the
1258 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1260 - fix a problem in Imager's "smart" handling of the color parameter
1262 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1265 Imager 0.50 - 29 Mar 2006
1268 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1269 or 4 channel image to jpeg or a 2 channel image to tga where the
1270 output is an in-memeory buffer.
1271 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1273 - fixes an incorrect pointer parameter in the PNG code
1274 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1276 - skip Inline::C tests when building in a directory with spaces
1277 http://rt.cpan.org/Public/Bug/Display.html?id=18049
