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 - update the bundled (and still modified) Devel::CheckLib
41 https://rt.cpan.org/Ticket/Display.html?id=69170
43 Imager 0.84_01 - 8 Aug 2011
46 Development release as a sanity check for the types re-work.
48 Massive types re-work:
50 - the type used internally for pixel co-ordinates and image sizes is
51 now 64-bit on 64-bit platforms (at least sane ones).
53 - size_t is now used consistently for memory block sizes.
55 - since this changes the binary interface, the Imager API version has
56 been incremented. Any module that uses the API will need to be
57 rebuilt. In most cases that will be enough, but calls to any APIs
58 that take a pointer to image sizes may need source changes.
60 - you should be able to create very large images on 64-bit systems,
61 if you have enough memory. Successfully created a 32768 x 49192 x
62 3 channel image, filled with a tiled image and scaled it. The
63 unscaled image was also successfully saved to a JPEG.
65 - check the image size before attempting to write BMP, GIF, JPEG,
66 PNG, SGI, TGA, TIFF images.
68 - correctly handle reading TGA images over 32767 pixels wide or tall.
72 - the gif_left and gif_top tags are now clamped to non-negative
73 values when writing a GIF image.
75 - removed dead callback read/write code
77 The default maximum memory size when reading files is now 1G.
79 Imager 0.84 - 20 Jun 2011
82 - Imager no longer inherits from Exporter (unless you're running an
85 - Imager can now write progressive JPEGs (it could always read them).
86 https://rt.cpan.org/Ticket/Display.html?id=68691
90 - re-work, document and test Imager's logging facility.
91 https://rt.cpan.org/Ticket/Display.html?id=65227
93 - fix META.yml testing and the generated META.yml
94 https://rt.cpan.org/Ticket/Display.html?id=65235
96 - test and add error reporting to to_*() family methods
98 - add to_rgb_double() method.
99 https://rt.cpan.org/Ticket/Display.html?id=65101
101 - Imager no longer exports anything by default
102 https://rt.cpan.org/Ticket/Display.html?id=65228
104 - convert colors to grayscale if the supplied (or generated) palette
105 contains only grays when performing error diffusion color
107 https://rt.cpan.org/Ticket/Display.html?id=68508
109 - writing a paletted image to GIF wouldn't always use the colors
110 supplied (or generated, eg. via make_colors => "mono"), which was
112 https://rt.cpan.org/Ticket/Display.html?id=67912
114 - replace (imager|tony)@imager.perl.org in the doc, since I don't
115 plan to continue receiving mail at that address.
116 https://rt.cpan.org/Ticket/Display.html?id=68591
118 Imager 0.83 - 21 May 2011
123 - diag() the error message on failure for some TIFF tests that are
124 failing on a Solaris smoker.
125 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
127 Imager 0.82_01 - 17 May 2011
130 Dev release, in case the compose tests are too sensitive.
134 - Imager::Font::T1 incorrectly checked for absolute filename under
135 Win32. Thanks to kmx for the report and fix.
136 https://rt.cpan.org/Ticket/Display.html?id=67963
138 - compose() with the target, source or mask position off the top or
139 left of the target image didn't clip the source image correctly.
140 https://rt.cpan.org/Ticket/Display.html?id=67220
142 - compose() now returns a useful error message on a non-positive
145 - compose.im now at 100% test coverage. (As opposed to, umm, much,
148 Imager 0.82 - 14 Mar 2011
153 - eliminate calls to i_has_format() from the test suite, since it's
154 no longer a useful way to check for file format support. Eliminate
155 i_has_format() from the functions exposed via XS.
156 https://rt.cpan.org/Ticket/Display.html?id=65863
158 - eliminate calls to note(), which isn't in the (very old) version of
159 Test::More we have as a pre-requisite. note() is modern enough
160 that I don't feel a need to require a Test::More upgrade for it.
161 https://rt.cpan.org/Ticket/Display.html?id=65864
163 - skip the threads tests on Test::More 2.00_*
164 https://rt.cpan.org/Ticket/Display.html?id=65812
166 - add an (unshipped) test to check Imager's internal POD links
167 https://rt.cpan.org/Ticket/Display.html?id=65749
169 - improve the library detection summary
170 https://rt.cpan.org/Ticket/Display.html?id=9675
172 - increase the version of Imager::Font::Type1 so that upgrades don't
173 downgrade the version in this file.
174 https://rt.cpan.org/Ticket/Display.html?id=66250
176 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
177 that option for the directories that would normally go in
178 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
179 https://rt.cpan.org/Ticket/Display.html?id=65955
181 Imager 0.81 - 14 Feb 2011
184 - added coverage tests for masked images (maskimg.c @100% test coverage)
186 - add hsv() method to Imager::Color
187 Thanks to Leolo (Philip Gwyn)
188 https://rt.cpan.org/Ticket/Display.html?id=65385
190 - split libt1 Type 1 font support into a sub-module
191 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
193 - add a preload() class method for use in forking servers, and to
194 work around limitations in PAR.
195 https://rt.cpan.org/Ticket/Display.html?id=65665
199 - paletted writes to a masked image are now masked correctly.
200 Revealed by new coverage tests.
202 - update the filter plugin documentation.
203 https://rt.cpan.org/Ticket/Display.html?id=56513
205 - add the matrix() method to Imager::Matrix2d to allow creation of a
206 matrix with specified co-efficients. You can now multiple an
207 Imager::Matrix2d object by a 9 element array ref or a number.
208 https://rt.cpan.org/Ticket/Display.html?id=29938
210 - really fix loading TTF fonts with FT2 when FT1 isn't available.
211 Thanks to Leolo (Philip Gwyn)
212 https://rt.cpan.org/Ticket/Display.html?id=65386
213 https://rt.cpan.org/Ticket/Display.html?id=62855
215 - make sure each test script that needs testout/ creates it.
216 https://rt.cpan.org/Ticket/Display.html?id=65088
218 - handle a slightly different warning from libtiff 4.x
219 https://rt.cpan.org/Ticket/Display.html?id=65268
221 - the sat transform2() op returned an incorrect saturation.
222 https://rt.cpan.org/Ticket/Display.html?id=65391
224 Imager 0.80 - 17 Jan 2011
227 - added coverage tests for Imager::Fountain and Imager::Color::Float
229 - Imager is now maintained in git
230 http://git.imager.perl.org/imager.git
231 git://git.imager.perl.org/imager.git
235 - images with an translucent alpha channel were not scaled correctly
236 by the default (qtype=normal) scaling method.
237 https://rt.cpan.org/Public/Bug/Display.html?id=63922
239 - Imager::Color::Float now translates "#FFFFFF" to white instead of
240 just a little darker.
242 - make the default color map build algorithm "mediancut". This
243 changes the default color map builder for writing GIFs back to what
244 it was in 0.77, reverting a performance regression.
245 https://rt.cpan.org/Ticket/Display.html?id=64785
247 - handle failure to create a masked image correctly
249 Imager 0.79 - 10 Dec 2010
252 - add Imager::Test to the POD coverage tests and document the missing
255 - the convert() method now optimizes the case where all output
256 channels are either 0, sourced from a single input channel or 1.
257 This significantly speeds up presets like "addalpha", "green".
258 https://rt.cpan.org/Ticket/Display.html?id=51254
260 - add wiggle.pl sample, as suggested by Dan Oppenheim.
262 - add the combine() method to combine channels from multiple source
263 images into a new image
264 https://rt.cpan.org/Ticket/Display.html?id=11872
268 - treat the co-efficients for convert() as doubles instead of floats.
270 - If a higher (earlier) priority font handler failed to load, that
271 would crash preventing loading of later font handlers.
272 https://rt.cpan.org/Ticket/Display.html?id=62855
274 - parse defines from the options returned by pkg-config --cflags
275 https://rt.cpan.org/Ticket/Display.html?id=63223
277 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
278 included in the tarball. They are now included.
280 Imager 0.78 - 4 Oct 2010
285 - don't access deprecated members of the png_structp.
286 https://rt.cpan.org/Ticket/Display.html?id=60242
288 - document that using color objects is faster than supplying colors
290 https://rt.cpan.org/Ticket/Display.html?id=61047
292 - Imager::Probe now accepts array references for incpath and libpath.
293 https://rt.cpan.org/Ticket/Display.html?id=60244
295 Imager 0.77_02 - 27 Sep 2010
298 - moved Win32, FreeType 2 font support into sub-modules.
299 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
300 Uses Imager::Probe now.
301 https://rt.cpan.org/Public/Bug/Display.html?id=61328
303 - tested successfully with jpeg-8b
304 https://rt.cpan.org/Ticket/Display.html?id=60221
308 - from _01: look for missing file support test files in the right
311 - flood_fill() wouldn't fill the right side of a single scan-line
313 Thanks to Nicolas Roggli for reporting this.
315 - flood_fill wouldn't fill to the left edge of the image if the
316 starting line didn't reach the left edge.
317 Thanks to Nicolas Roggli for reporting this.
319 Imager 0.77_01 - 13 Sep 2010
322 - add each library-directory/pkgconfig/ to the pkg-config search path
324 Thanks to Justin Davis.
325 https://rt.cpan.org/Ticket/Display.html?id=60491
327 - moved GIF, TIFF, JPEG file handling code into sub-modules in
328 preparation for separate distribution.
329 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
331 - optimize filled box drawing (color, not fill)
335 - Imager::Probe was calling ExtUtils::Liblist to initialize
336 LD_RUN_PATH supplying an undefined value rather than the found
337 directory. Thanks to Justin Davis.
338 https://rt.cpan.org/Ticket/Display.html?id=60491
340 - only prepend ./ to font filenames when passing them to T1Lib and
341 then only when it would use its search mechanisms.
342 https://rt.cpan.org/Ticket/Display.html?id=60509
344 - fix the cache check for the X rgb.txt loader. This is typically
345 used for color translation on Unix-like systems, and the fix
346 improves performance of supplying colors by name by about 80 times.
347 Test code that managed 3400 10x10 pixel boxes/second sped up to
350 - clarify that Imager doesn't write EXIF metadata to images.
351 https://rt.cpan.org/Ticket/Display.html?id=60637
353 - Imager::Probe can now search subdirectories under its include path.
354 Used by the PNG Makefile.PL to find headers and libraries when they
355 aren't in the base directory, as in cygwin.
356 https://rt.cpan.org/Ticket/Display.html?id=60635
358 Imager 0.77 - 11 Aug 2010
361 I don't want Imager::File::PNG indexed as part of Imager, but forgot
362 to update the META.yml before updating the version.
364 - don't index Imager::File::PNG as part of Imager
366 - add resources to META.yml
368 Imager 0.76 - not released
373 - the align_string() method would ignore a string of "0" due to a
375 Thanks to Maurice Height for reporting this.
376 https://rt.cpan.org/Ticket/Display.html?id=60199
378 Imager 0.75_03 - 09 Aug 2010
383 - read_types() and write_types() would include png when it wasn't
384 available due to a problem with the %formats tie
386 - handle dependent libraries correctly (eg -lpng requiring -lz) in
387 the code run phase of library probing.
389 Imager 0.75_02 - 07 Aug 2010
394 - add file missing from MANIFEST, which was causing TIFF failures.
396 Imager 0.75_01 - 06 Aug 2010
399 Test release for the new PNG probe.
401 - added the ability to read multiple-image PNM files.
402 Note that unlike the pbm/pgm/ppm specification this accepts mixed
403 format files and allows white space padding between files.
404 Thanks to Philip Gwyn (Leolo) for this patch.
406 - moved the PNG file handling code into a sub-module in preparation
407 for separate distribution.
408 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
409 Also helps avoid complications from -I/-L compile/link options from
414 - Imager->new(data => $data) didn't try to process image file data in
416 https://rt.cpan.org/Ticket/Display.html?id=58761
418 - t/t50basicoo.t no longer depends on the other tests to generate its
420 https://rt.cpan.org/Ticket/Display.html?id=9798
421 Also, it wasn't testing pnm (pnm vs ppm mix-up)
423 - update the documentation of hardinvert to match the change in 0.62.
424 https://rt.cpan.org/Ticket/Display.html?id=59785
426 - added hardinvertall filter which also inverts the alpha channel
429 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
430 the probe can find the library for the test run.
431 https://rt.cpan.org/Ticket/Display.html?id=57518
433 Imager 0.75 - 20 Jun 2010
436 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
441 - an opacity fill based on a fountain fill would segfault when
442 filling an 8-bit/sample image.
444 - merge thickline branch polygon fix
445 https://rt.cpan.org/Ticket/Display.html?id=43518
447 Imager 0.74 - 7 May 2010
452 - read_multi() didn't handle a missing file format library correctly,
453 aborting on failing to call i_readgif_multi_wiol() or
454 i_readtiff_multi_wiol().
456 - fix spelling errors patched by Debian
457 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
459 - add an (unshipped) author test to spellcheck Imager's POD.
461 - update the TIFF file format documentation
462 https://rt.cpan.org/Ticket/Display.html?id=56510
464 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
466 Imager 0.73 - 15 Mar 2010
469 - implement outline circles, both anti-aliased and not
470 https://rt.cpan.org/Ticket/Display.html?id=19755
472 - a combine => "none" fill to a 1 or 3 channel image would produce
473 the incorrect colour.
475 Imager 0.72 - 09 Dec 2009
478 Bump version for release, since 0.71_03 is stable with CPAN testers.
480 Imager 0.71_03 - 5 Dec 2009
483 - further adjust the threads test so it only performs the tests on
484 perls where it's expected to work, and only if the threads module
487 Imager 0.71_02 - 1 Dec 2009
490 - adjust the way we load the threads module for the threads test so
491 it works with non-threaded perls
493 Imager 0.71_01 - 30 Nov 2009
498 - use scanline oriented operations to flip images instead of pixel
500 https://rt.cpan.org/Ticket/Display.html?id=39278
502 - use double/sample operations to flip large sample images instead of
503 8-bit sample operations.
504 https://rt.cpan.org/Ticket/Display.html?id=39280
507 https://rt.cpan.org/Ticket/Display.html?id=51874
509 - prevent double-frees when someone creates Imager objects and then
510 creates a thread. Note: this just handles some simple cases,
511 Imager doesn't support perl threads, and isn't likely to.
512 https://rt.cpan.org/Ticket/Display.html?id=52268
514 Imager 0.71 - 16 Nov 2009
517 - add the opacity fill type - an adaptor that modifies the opacity of
522 - the conv filter now enforces that the sum of the coefficients is
523 non-zero. Also, rather than skipping pixels off the edge off the
524 edge of the image, the closest edge pixel is used. Previously
525 dividing by the zero sum of coefficients could cause invalid
526 results or runtime exceptions.
527 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
530 Imager 0.70 - 21 Sep 2009
535 - release image row and comments memory on all error returns in gif
538 - handle zero length extensions, previously this would cause a null
540 Thanks to Krzysztof Wojtaś for the test data and fix for this.
542 - an integer division meant that preview scaling to below 1 pixel
543 wide or high (which isn't too useful anyway) was calculating using
544 NaNs on most platforms, and causing an exception on others.
545 Thanks to David Cantrell for producing a backtrace of the crash on
546 his Alpha-NetBSD CPAN test box which made it possible to track this
549 Imager 0.69 - 08 Sep 2009
554 - broken test fix - was attempting to call a function skip_all, when
555 that should be a parameter to plan().
557 - briefly document apidocs.perl, the tool used to build
558 Imager::APIRef and make some minor enhancements
560 - various minor documentation enhancements and fixes.
562 Imager 0.68 - 07 Sep 2009
565 - Imager->new(file => $filename) and other similar incantations will
567 https://rt.cpan.org/Ticket/Display.html?id=48261
571 - avoid using CHECK as a label in Imager::Test
572 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
574 - re-work most image file test files that require a library into
575 separate library present/not present files to remove stupidly long
578 - don't treat rubthrough() outside the bounds of the target image as
580 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
582 Imager 0.67_01 - 02 Sep 2009
587 - correct documentation of default of raw image interleave read
589 https://rt.cpan.org/Ticket/Display.html?id=42074
591 - add raw_ prefix to raw read parameters, though the original names
594 - fail the read if an invalid raw_interleave parameter is supplied
596 - warn if no interleave or raw_interleave parameter is supplied,
597 since the documented default was wrong, and incompatible with the
600 - for reading raw images, if raw_storechannels > raw_datachannels,
601 set the extra channels in the image to 0
603 - when probing for executables like freetype-config, search for .bat
604 and .cmd on MSWin32, as well as .exe.
605 https://rt.cpan.org/Ticket/Display.html?id=49275
607 - re-work the external libraries section of README:
608 - list Debian and Redhat package names for each library
612 - use the new EU::MM META_MERGE facility instead of generating
613 META.yml from scratch
614 https://rt.cpan.org/Ticket/Display.html?id=47888
616 - use Devel::CheckLib (bundled, modified) to check which release of
617 libtiff is installed and reject 3.9.0
618 http://bugzilla.maptools.org/show_bug.cgi?id=2088
619 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
621 Imager 0.67 - 12 Dec 2008
626 - fix a packaging error
628 Imager 0.66 - 12 Dec 2008
631 - 24-bit color .ICO/.CUR files can now be read.
635 - an optimization skipping 0 src alpha values could cause the
636 rubthrough() to read past the end of a buffer.
637 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
639 - corrected a reference leak where writing GIFs would leak memory.
640 This could also happen calling to_paletted().
641 Also documented the underlying long existing feature where the
642 colors parameter is filled with the generated color table and added
644 http://rt.cpan.org/Ticket/Display.html?id=41028
646 - write out the image size in bytes field of a BMP correctly.
647 http://rt.cpan.org/Ticket/Display.html?id=41406
649 - add limited tests for Imager::ExtUtils
651 - make Imager::ExtUtils->includes use an absolute path, since
652 a relative path could cause failures using Inline::C.
653 http://rt.cpan.org/Ticket/Display.html?id=37353
655 - re-arrange the POD for Imager::Font::BBox:
656 - mark total_width(), pos_width(), end_offset() obsolete, since
657 they're mostly for backwards compatibility
658 - group width methods and height methods
659 https://rt.cpan.org/Ticket/Display.html?id=39999
661 Imager 0.65 - 20 May 2008
666 - In some cases when an error occurs reading those parts of a JPEG
667 file after the image the scan-line buffer could be freed a second
668 time. In cases where the the error occured while reading the image
669 data it's possible that the buffer could have leaked.
670 Thanks to Gabriel Vasseur for reporting this and help in tracking
673 - the gif_screen_height tag was overriding the screen width and being
674 ignored for the screen height when present.
675 https://rt.cpan.org/Public/Bug/Display.html?id=35568
677 Imager 0.64 - 23 April 2008
680 This is a bug fix release. This includes a fix for a possible
685 - Possible security issue: The floating point sample path for image
686 based fills had a buffer overflow. This would overwrite the end of
687 a malloc()ed buffer with double precision floats.
688 http://rt.cpan.org/Ticket/Display.html?id=35324
691 - check that the result of fileno($fh) is defined rather than simply
692 true when read() or write() is supplied with an fh parameter.
693 http://rt.cpan.org/Ticket/Display.html?id=35139
695 - i_scale_axis() wasn't checking the result of i_img_new_ch()
696 resulting in a SIGSEGV when attempting to scale an image to a size
697 too large to fit in memory. This is a NULL pointer access issue,
698 not a buffer overflow.
699 Added a check for the failure.
700 scale_calculate() (and hence scale()) will now fail if any of the
701 scale size parameters are a reference.
702 http://rt.cpan.org/Ticket/Display.html?id=35172
704 - Regression: filling a greyscale image with a hatch used the wrong
705 color channels from the supplied fg/bg colors.
706 https://rt.cpan.org/Ticket/Display.html?id=35278
708 - fixed a related problem for image fills.
710 Imager 0.63 - 7 April 2008
713 This release primarily contains changes to improve ease of use -
714 rather than you having to convert images to the appropriate number of
715 channels, Imager handles it internally. How to handle drawing colors
716 and the default combine mode is a thornier problem left for some other
719 - the font libraries are now only initialized when needed.
720 http://rt.cpan.org/Ticket/Display.html?id=28825
722 - moved the imtoc.perl code into Imager::Preprocess
724 - paste() and rubthrough() now adapt the source image data to the
725 destination, so you can now safely paste/rubthrough from greyscale
726 images to color images or back, or from alpha channel images to
727 noalpha channels or back.
728 https://rt.cpan.org/Ticket/Display.html?id=30908
730 - rubthrough() now falls back to pasting when the source doesn't have
731 an alpha channel. This effectively treats the source as having a
732 max alpha channel, the right thing to do.
733 http://rt.cpan.org/Ticket/Display.html?id=29944
735 - re-worked most of the area filling code to use a common set of
736 functions when filling.
737 Corrected normal combine mode.
738 Rewrote most of the combine modes to match the way the SVG draft
739 defines them with respect to a translucent source and destination.
740 Added tests for translucent source and destination.
741 Added tests to check 8-bit/sample and double/sample combines work
743 https://rt.cpan.org/Ticket/Display.html?id=29879
745 - writing a 2 or 4 channel image to a JPEG file will now write that
746 image as if composited against a background, black by default,
747 overridable with the i_background tag/parameter.
748 https://rt.cpan.org/Ticket/Display.html?id=29876
750 - writing a 2 or 4 channel image to a PGM/PPM file will now write
751 that image as if composited against a background, black by default,
752 overridable with the i_background tag/parameter.
753 http://rt.cpan.org/Ticket/Display.html?id=30074
755 - writing a 2 or 4 channel image to a BMP file will now write that
756 image as if composited against a background, black by default,
757 overridable with the i_background tag/parameter.
758 http://rt.cpan.org/Ticket/Display.html?id=30075
762 - Imager::Matrix2d->translate() now only requires one of the x or y
764 http://rt.cpan.org/Ticket/Display.html?id=29937
766 - mixing qtype scaling now sets all channels of a pixel to zero if
767 the pixel has zero coverage (zero alpha). This should produce more
768 compressible output files.
769 http://rt.cpan.org/Ticket/Display.html?id=32324
771 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
773 https://bugzilla.redhat.com/show_bug.cgi?id=166254
774 I'm not changing the #! lines of the sample code, since it's sample
775 code, not intended for installation.
776 http://rt.cpan.org/Ticket/Display.html?id=33408
778 - some TGA images weren't being detected correctly as TGA images
779 https://rt.cpan.org/Ticket/Display.html?id=32925
781 - handling of the left-over bit for 16-bit/pixel TGA images has been
782 changed to match the behaviour of the GIMP. Previously the bit
783 being set was treated as an opaque pixel, but one user reported a
784 problem with loading such an image. I haven't been able to find any
785 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
786 I'll match it's behaviour. See issue 114913 in the GIMP's
788 http://rt.cpan.org/Ticket/Display.html?id=32926
790 Imager 0.62 - 10 December 2007
793 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
794 to /path under your home directory.
795 http://rt.cpan.org/Ticket/Display.html?id=29484
797 - the old dynaload code used Mach API functions to load dynamic
798 libraries on Mac OS X. These APIs have been deprecated in OS X
799 10.5 and were causing some build problems.
800 So henceforth Imager uses the dlopen() family of functions, and you
801 will need version 10.3 or later of OS X.
803 - added the det() function to the transform2() engine.
804 added the sample quad_to_square.pl
805 Courtesy Richard Fairhurst.
806 http://rt.cpan.org/Ticket/Display.html?id=31244
810 - samples/gifscale.pl sourced the base value for gif_top from
812 Thanks to Eleneldil G. Arilou for pointing this out.
814 - t/t82inline.t no longer loads B at runtime, to work around a bug
815 in some 5.005_0[45] installations.
816 http://rt.cpan.org/Ticket/Display.html?id=30508
818 - work around Module::Depends::Intrusive bug #21229
819 http://rt.cpan.org/Ticket/Display.html?id=30520
821 - the hardinvert filter no-longer inverts the alpha channel.
822 http://rt.cpan.org/Ticket/Display.html?id=30002
824 - the hardinvert filter now supports large samples
826 Imager 0.61_02 - 28 November 2007
829 - major TIFF support re-work
830 http://rt.cpan.org/Ticket/Display.html?id=20329
832 - added a C level image interface for accessing samples from 1-32
833 bits, exposed this at the perl level in getsamples()
835 - the conv filter now works at floating point precision for high bit
838 - added is_bilevel method to test whether an image should be written as
839 a bilevel image if the image format supports it.
841 - added -log-stderr as an Imager import list option
843 - added some important types to Imager::APIRef
845 - added test_image_double() to Imager::Test
849 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
852 - the scale() method with qtype mixing now handles images with an
853 alpha channel correctly.
855 - fixed a broken link from the "animated GIF" entry in the concept index.
856 Thanks to Slaven Rezic.
857 http://rt.cpan.org/Ticket/Display.html?id=30889
859 - on some perl's the infix expression parser test would fail due to
860 actions in the grammar returning false. Made sure all actions return
862 Thanks to Richard Fairhurst for spending a lot of time in tracking
864 http://rt.cpan.org/Public/Bug/Display.html?id=29562
866 Imager 0.61 - 5 November 2007
869 - added samples/gifscale.pl, which adjusts the screen size/position tags
870 when scaling an animated gif
871 http://rt.cpan.org/Ticket/Display.html?id=27591
875 - correct handling of sz in matrix_transform() - this should allow
876 perspective type transformations to work now.
877 http://rt.cpan.org/Ticket/Display.html?id=29936
879 - prevent a cast to integer warning on x64 builds in datatypes.c
880 also fixed some other type warnings
881 https://rt.cpan.org/Ticket/Display.html?id=30204
883 - some sub-directory tests depended on files produced by the parent
885 http://rt.cpan.org/Ticket/Display.html?id=30203
887 - Imager::Font::Wrap doesn't correctly set savepos
888 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
889 http://rt.cpan.org/Ticket/Display.html?id=29771
891 - test 171 in t/t01introvert.t was failing on perls configured to
893 http://rt.cpan.org/Ticket/Display.html?id=29413
895 - the code for the transform2() uminus operator was missing a break.
896 Added tests for better code coverage of the ops.
897 http://rt.cpan.org/Ticket/Display.html?id=29296
899 - the SGI RLE compression code could overflow its compression buffer
900 http://rt.cpan.org/Ticket/Display.html?id=30334
902 - the 32-bit output function used by the SGI code only handled values
903 under 0x10000. This was most noticable when writing large RLE images.
904 http://rt.cpan.org/Ticket/Display.html?id=30335
906 - validate chan_count for chans == NULL for each of the i_gsamp()
908 http://rt.cpan.org/Ticket/Display.html?id=28985
910 - attempt to work around the test failure at
911 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
912 http://rt.cpan.org/Ticket/Display.html?id=29562
914 - improve the error messages produced when attempting to read or write
915 an unknown image file format.
916 http://rt.cpan.org/Ticket/Display.html?id=30103
918 - improve the transform2() documentation
919 http://rt.cpan.org/Ticket/Display.html?id=29267
921 - correctly generate the author key in META.yml
922 http://rt.cpan.org/Ticket/Display.html?id=30377
924 - correctly blend a rotated (or matrix_transformed()) image when
925 performing interpolation in the presence of an alpha channel.
926 Also corrected the centring of the rotated image on the output
929 Imager 0.60 - 30 August 2007
932 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
933 now has full SGI RGB image format, including RLE and 16-bit/sample
935 https://rt.cpan.org/Ticket/Display.html?id=8666
937 - logging functions are now available in the API
939 - applied Gabriel Vasseur's patch
940 added documentation, further tests, and support for greyscale images
941 Obviously problems are my fault :)
942 https://rt.cpan.org/Ticket/Display.html?id=28142
944 - the mask for ICO/CUR images is now applied as an alpha channel to
945 the returned image. For the old behaviour, supply ico_masked => 0
946 to read() or read_multi(). This should be less confusing when
947 using Imager as a general image processor.
948 https://rt.cpan.org/Ticket/Display.html?id=29001
952 - in some cases it's possible for giflib/libungif to return color
953 indexes outside the range of colors defined by the image's palette.
954 We now expand the palette to match the indexes used.
955 Thanks to Gabriel Vasseur for reporting this.
957 - fixed various memory leaks that could occur when failing to read png,
958 jpeg, bmp or tga files.
960 - to avoid confusion, channels not present in the image are returned as
961 zero by getscanline(). This has no effect on the C level i_glin()
962 and i_glinf() API functions which continue to not set the unused
965 - the convert() method now returns an image of the same sample size as
967 https://rt.cpan.org/Ticket/Display.html?id=28492
969 - remove repeated text in Imager::Files
970 http://rt.cpan.org/Ticket/Display.html?id=27589
972 - be even more explicit that scale() and friends don't modify the source
973 image, but return a new image.
974 http://rt.cpan.org/Ticket/Display.html?id=28570
976 - improve the error message from errstr() when you try to load a font
977 for which the driver hasn't been built in Imager.
978 http://rt.cpan.org/Ticket/Display.html?id=27571
980 - transparency is now enabled by default when writing GIF images
981 http://rt.cpan.org/Ticket/Display.html?id=27615
983 - Imager would not load on Windows 98
984 http://rt.cpan.org/Ticket/Display.html?id=27653
986 Imager 0.59 - 14 June 2007
991 - fixes a regression introduced by the fixes for RT 11972
992 http://rt.cpan.org/Ticket/Display.html?id=27546
994 - cropping outside the image would return an Imager object with
995 no low-level image object, instead of returning false.
996 Fixed by: Philip Gwyn (Leolo)
997 http://rt.cpan.org/Ticket/Display.html?id=27509
999 Imager 0.58 - 16 May 2007
1002 No significant changes from 0.57_01.
1004 Imager 0.57_01 - 11 May 2007
1007 - added to_rgb16 to produce a 16-bit/sample version of an image
1009 - improve freetype 1.x text output efficiency
1013 - search another place for rgb.txt, and check all the places
1014 Imager::Color checks when deciding whether to skip testing it
1015 http://rt.cpan.org/Ticket/Display.html?id=26064
1017 - use a convolution kernel size based on the stddev rather than a
1018 fixed size when performing a gaussian blur
1019 http://rt.cpan.org/Ticket/Display.html?id=25645
1021 - document the difference() method's mindist parameter, and debug it.
1023 - put the Imager release number in the Inline::C generated code to
1024 regenerate Inline code when a new release of Imager is installed.
1025 http://rt.cpan.org/Ticket/Display.html?id=26278
1027 - fix rendering on alpha channel images for the FreeType 1.x driver.
1028 http://rt.cpan.org/Ticket/Display.html?id=11972
1030 - fix rendering on alpha channel images for the T1lib driver.
1031 http://rt.cpan.org/Ticket/Display.html?id=11972
1033 - reworked library probing, we can now set more than one probe
1034 function for a library. Disabled the default (non-freetype-config)
1035 library probe and added an extra probe function that searches for
1036 both ft2build.h and whatever it includes, and adds -I as needed.
1037 Hopefully this will fix build problems like
1038 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
1039 http://rt.cpan.org/Ticket/Display.html?id=26086
1041 Imager 0.57 - 30 Apr 2007
1044 This is a maintenence release fixing a security issue in Imager.
1046 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
1047 overflow in malloced memory. There will be further discussion of
1048 this issue in the ticket below.
1049 http://rt.cpan.org/Ticket/Display.html?id=26811
1050 CVE-2007-2459 CVE-2007-2413
1051 The descriptions at cve.mitre.org varied in quality, please see the
1052 ticket at rt.cpan.org for a more accurate description of the issue.
1054 Imager 0.56 - 1 Apr 2007
1057 - added support for reading 16-bit/sample PGM/PPM images
1059 - added support for writing 16-bit/sample PGM/PPM images
1061 - improved performance of reading PBM/PGM/PPM images
1063 - added support for writing PBM images if the image is paletted and
1064 contains only black and white
1066 - added a new make_colors value - "mono"
1068 - switched from the svn log Changes to a manual Changes to reduce
1071 - new sample code - samples/flasher.pl
1075 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
1076 was returning an image object with an extra reference, this
1077 resulted in a memory leak.
1078 http://rt.cpan.org/Ticket/Display.html?id=24992
1080 - fix rendering on alpha channel images for the FreeType 2.x driver
1081 http://rt.cpan.org/Ticket/Display.html?id=11972
1083 - reading bmp files now consitently handles short reads. You can now
1084 supply a parameter to treat a short read as successful and set
1086 http://rt.cpan.org/Ticket/Display.html?id=8426
1088 - previously, reading ASCII PBM files required spaces between samples,
1089 even though the format doesn't require that
1091 - improved documentation of the unsharpmask filter (I hope)
1092 http://rt.cpan.org/Ticket/Display.html?id=25531
1094 - force flushing of the output from i_tt_dump_names() and test output
1095 in t/t35ttfont.t to prevent output from being mixed up.
1096 https://rt.cpan.org/Ticket/Display.html?id=24859
1098 - rewrite a conditional expression as an if() to hopefully work around
1099 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
1100 https://rt.cpan.org/Ticket/Display.html?id=25561
1102 - avoid Data::Dumper in regops.perl to support older releases of perl
1103 https://rt.cpan.org/Ticket/Display.html?id=24391
1105 Imager 0.55 - 16 Dec 2006
1108 This is primarily a bug fix release.
1110 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1112 There is one new feature:
1114 - the Win32 font driver now supports UTF8 (RT 22166)
1115 http://www.cpanforum.com/threads/3276
1116 http://rt.cpan.org/Ticket/Display.html?id=22166
1118 Several bugs were fixed:
1120 - the string() method would not output the string "0"
1121 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1123 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1124 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1126 - the gif_disposal and gif_user_input tags weren't being read from
1128 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1130 - gif.c was failing to build under MSVC
1131 http://rt.cpan.org/Ticket/Display.html?id=23922
1133 - in some cases strings passed to the string() method were treated as
1134 terminated by NUL (chr 0)
1135 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1137 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1138 that's the default build name for zlib on Win32.
1139 http://rt.cpan.org/Ticket/Display.html?id=23064
1141 - search $Config{incpath} for headers too, which we should have been
1144 Win32 font driver fixes:
1146 - the global descent value from bounding box was the wrong sign
1147 http://www.cpanforum.com/threads/3276
1149 - if the first or last glyph overflowed the left or right side of the
1150 advance width they would be clipped
1153 Imager 0.54 - 14 Sep 2006
1156 This is primarily a feature release:
1158 - a new qtype value 'mixing' has been added to the scale()
1159 method. This is faster than 'normal', slower than 'preview'. This
1160 is based on the method used by pnmscale, and seems to produce less
1161 blurry results than normal.
1162 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1164 - the rubthrough() method can now render onto images with an alpha
1166 http://rt.cpan.org/Ticket/Display.html?id=20678
1168 - the read_multi() method now falls back to calling doing a single
1169 image read via the read() method and write_multi() will now fall
1170 back to calling write() if a single image is supplied. This means
1171 you can simply call the read_multi() or write_multi() functions
1172 without having to check if the type is formatted by that method.
1173 http://rt.cpan.org/Ticket/Display.html?id=19457
1174 http://rt.cpan.org/Ticket/Display.html?id=19458
1176 - the GIF loop extension can now be written. If you don't have
1177 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1179 http://rt.cpan.org/Ticket/Display.html?id=21185
1181 - getscanline() and setscanline() can now read/write palette index
1182 based data from/to the image for paletted images, by setting type to
1184 http://rt.cpan.org/Ticket/Display.html?id=20338
1186 - we no longer hassle you to disable GIF support
1187 http://rt.cpan.org/Ticket/Display.html?id=20687
1189 - minor documentation fixes
1192 Imager 0.53 - 26 Jul 2006
1195 This is a bugfix release.
1197 Some test code was left in a code path not covered by the test
1198 suite. A test was added to cover this code path and the test code was
1200 http://rt.cpan.org/Public/Bug/Display.html?id=20705
1203 Imager 0.52 - 25 Jul 2006
1206 This is primarily a feature release, but contains a fair few bug
1207 fixes, new features:
1209 - ability to read and write MS Windows ICO and CUR files
1211 - you can now add file format plugins to support new file formats
1213 - add POD coverage tests
1215 - setcolors() and addcolors() now accept color names and so on
1216 instead of requiring Imager::Color objects.
1217 http://rt.cpan.org/Ticket/Display.html?id=20056
1219 - flood_fill() can now fill to a specified border color instead of
1220 just to the area the same color as the seed.
1221 http://rt.cpan.org/Ticket/Display.html?id=19618
1226 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1227 calculating the advance width.
1228 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1230 - bounding_box for the T1 driver wasn't including leading and
1231 trailing spaces in the bounding box as the other drivers did, it also
1232 produced strange results for empty strings or strings containing only
1235 - when reading CMYK jpeg images they were being transferred to the
1236 image object as is, producing a four channel image. It only looked ok
1237 due to an old still unfixed Photoshop bug. We now convert from the
1238 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1239 http://rt.cpan.org/Ticket/Display.html?id=20416
1241 - reading a CYMK TIFF would result in a 4 channel image, reading any
1242 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1244 http://rt.cpan.org/Ticket/Display.html?id=20415
1246 - added /usr/local/include to the default include search path, since
1247 we were already searching /usr/local/lib for libraries.
1249 And various minor fixes and documentation updates.
1252 Imager 0.51 - 23 Apr 2006
1255 - fix a validation bug when processing JPEG EXIF data that can cause
1257 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1259 - fix mis-processing of the src_maxx and src_maxy parameters of the
1261 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1263 - fix a problem in Imager's "smart" handling of the color parameter
1265 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1268 Imager 0.50 - 29 Mar 2006
1271 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1272 or 4 channel image to jpeg or a 2 channel image to tga where the
1273 output is an in-memeory buffer.
1274 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1276 - fixes an incorrect pointer parameter in the PNG code
1277 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1279 - skip Inline::C tests when building in a directory with spaces
1280 http://rt.cpan.org/Public/Bug/Display.html?id=18049
