1 Imager release history. Older releases can be found in Changes.old
3 Imager 0.86 - unreleased
8 - eliminate unused i_gif_opts type (clean-up)
9 https://rt.cpan.org/Ticket/Display.html?id=69245
11 Imager 0.85_01 - 10 Oct 2011
14 - add simple tests for the Imager::Test test_image generators
16 - io_glue I/O buffering re-work:
18 - reorganize io_glue to do it's own buffering by default
20 - the unbuffered functions are available as i_io_raw_read() (or
21 raw_read() from perl) etc but are not recommended for typical
24 - use the new i_io_peekn() when checking for file magic to avoid
25 seek, allowing Imager to detect the file type and read the file
26 from an unseekable stream (for formats that don't use random
29 - added several new I/O layer API functions.
31 - fix the TGA performance problem, most noticably on Win32
32 https://rt.cpan.org/Ticket/Display.html?id=70037
34 - TIFF now uses wrapper functions of the correct types to avoid casts
35 https://rt.cpan.org/Ticket/Display.html?id=69912
37 - the callback IO object did its own buffering, controlled by the
38 maxbuffer parameter supplied to the read() and write() methods.
39 This buffering has been removed, to avoid redundancy with the
40 common io_glue buffering. This also avoids a bug in that code
41 which could rarely pass a zero length to the read callback and
42 then panic about the result.
44 - the callback IO object now tests the result of calling the close
45 callback, which should return true for success.
47 - the PNM reader did its own buffering. This buffering has been
48 removed to avoid redundancy with the common io_glue buffering.
50 - previously the read handlers for fd and callback I/O layers would
51 call the underlying interface (POSIX read or your supplied callback)
52 until it filled the buffer. It now only makes one call.
54 - added public constructors for I/O layer objects (see Imager::IO)
56 - all core file handlers now use the i_io_foo() wrappers to gain
57 access to buffered I/O rather than calling the I/O layer
60 - all core file handlers now check for error on close.
62 - Backward compatibility: if you hava custom file handlers, you can
63 use i_io_write() etc since they're available as macros in older
66 - eliminate the final remnants of io_glue_commit_types().
68 - bump IMAGER_API_VERSION, since the above may break assumptions.
70 - removed the long unused i_gen_reader() and i_gen_writer() utility
73 Imager 0.85 - 29 Aug 2011
76 The main changes in the release versus 0.84 are:
78 - on 64-bit systems, 64-bit types are consistently used for image
79 dimensions and co-ordinated, and for memory block sizes.
81 - handle IFD loops in TIFF files correctly. Previously this would
82 lead to an infinite loop.
86 - fix the link in the getheight() entry in the method index
88 Imager 0.84_02 - 22 Aug 2011
91 Development release, this will become 0.85 if CPAN testers is
96 - the image file limits set by set_file_limits() weren't being
97 checked when reading TIFF files.
98 https://rt.cpan.org/Ticket/Display.html?id=69915
100 - Provide more information about file format module load errors on a
101 failed image file read() or write().
102 https://rt.cpan.org/Ticket/Display.html?id=69194
104 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
105 through TIFF images, since it checks for IFD loops.
106 https://rt.cpan.org/Ticket/Display.html?id=69914
108 - don't leak memory when out of range palette indexes are supplied to
110 https://rt.cpan.org/Ticket/Display.html?id=69242
112 - require a later version of CPAN::Meta to ensure JSON::PP and
113 CPAN::Meta::YAML are available.
114 https://rt.cpan.org/Ticket/Display.html?id=69008
116 - hoist the per-line calculations for the flines implementations, and
117 modernize the tests a bit.
118 https://rt.cpan.org/Ticket/Display.html?id=70126
120 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
122 https://rt.cpan.org/Ticket/Display.html?id=69147
124 - if t1lib failed to reinitialize it would be left as marked
126 https://rt.cpan.org/Ticket/Display.html?id=69877
128 - update the bundled (and still modified) Devel::CheckLib
129 https://rt.cpan.org/Ticket/Display.html?id=69170
131 Imager 0.84_01 - 8 Aug 2011
134 Development release as a sanity check for the types re-work.
136 Massive types re-work:
138 - the type used internally for pixel co-ordinates and image sizes is
139 now 64-bit on 64-bit platforms (at least sane ones).
141 - size_t is now used consistently for memory block sizes.
143 - since this changes the binary interface, the Imager API version has
144 been incremented. Any module that uses the API will need to be
145 rebuilt. In most cases that will be enough, but calls to any APIs
146 that take a pointer to image sizes may need source changes.
148 - you should be able to create very large images on 64-bit systems,
149 if you have enough memory. Successfully created a 32768 x 49192 x
150 3 channel image, filled with a tiled image and scaled it. The
151 unscaled image was also successfully saved to a JPEG.
153 - check the image size before attempting to write BMP, GIF, JPEG,
154 PNG, SGI, TGA, TIFF images.
156 - correctly handle reading TGA images over 32767 pixels wide or tall.
160 - the gif_left and gif_top tags are now clamped to non-negative
161 values when writing a GIF image.
163 - removed dead callback read/write code
165 The default maximum memory size when reading files is now 1G.
167 Imager 0.84 - 20 Jun 2011
170 - Imager no longer inherits from Exporter (unless you're running an
173 - Imager can now write progressive JPEGs (it could always read them).
174 https://rt.cpan.org/Ticket/Display.html?id=68691
178 - re-work, document and test Imager's logging facility.
179 https://rt.cpan.org/Ticket/Display.html?id=65227
181 - fix META.yml testing and the generated META.yml
182 https://rt.cpan.org/Ticket/Display.html?id=65235
184 - test and add error reporting to to_*() family methods
186 - add to_rgb_double() method.
187 https://rt.cpan.org/Ticket/Display.html?id=65101
189 - Imager no longer exports anything by default
190 https://rt.cpan.org/Ticket/Display.html?id=65228
192 - convert colors to grayscale if the supplied (or generated) palette
193 contains only grays when performing error diffusion color
195 https://rt.cpan.org/Ticket/Display.html?id=68508
197 - writing a paletted image to GIF wouldn't always use the colors
198 supplied (or generated, eg. via make_colors => "mono"), which was
200 https://rt.cpan.org/Ticket/Display.html?id=67912
202 - replace (imager|tony)@imager.perl.org in the doc, since I don't
203 plan to continue receiving mail at that address.
204 https://rt.cpan.org/Ticket/Display.html?id=68591
206 Imager 0.83 - 21 May 2011
211 - diag() the error message on failure for some TIFF tests that are
212 failing on a Solaris smoker.
213 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
215 Imager 0.82_01 - 17 May 2011
218 Dev release, in case the compose tests are too sensitive.
222 - Imager::Font::T1 incorrectly checked for absolute filename under
223 Win32. Thanks to kmx for the report and fix.
224 https://rt.cpan.org/Ticket/Display.html?id=67963
226 - compose() with the target, source or mask position off the top or
227 left of the target image didn't clip the source image correctly.
228 https://rt.cpan.org/Ticket/Display.html?id=67220
230 - compose() now returns a useful error message on a non-positive
233 - compose.im now at 100% test coverage. (As opposed to, umm, much,
236 Imager 0.82 - 14 Mar 2011
241 - eliminate calls to i_has_format() from the test suite, since it's
242 no longer a useful way to check for file format support. Eliminate
243 i_has_format() from the functions exposed via XS.
244 https://rt.cpan.org/Ticket/Display.html?id=65863
246 - eliminate calls to note(), which isn't in the (very old) version of
247 Test::More we have as a pre-requisite. note() is modern enough
248 that I don't feel a need to require a Test::More upgrade for it.
249 https://rt.cpan.org/Ticket/Display.html?id=65864
251 - skip the threads tests on Test::More 2.00_*
252 https://rt.cpan.org/Ticket/Display.html?id=65812
254 - add an (unshipped) test to check Imager's internal POD links
255 https://rt.cpan.org/Ticket/Display.html?id=65749
257 - improve the library detection summary
258 https://rt.cpan.org/Ticket/Display.html?id=9675
260 - increase the version of Imager::Font::Type1 so that upgrades don't
261 downgrade the version in this file.
262 https://rt.cpan.org/Ticket/Display.html?id=66250
264 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
265 that option for the directories that would normally go in
266 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
267 https://rt.cpan.org/Ticket/Display.html?id=65955
269 Imager 0.81 - 14 Feb 2011
272 - added coverage tests for masked images (maskimg.c @100% test coverage)
274 - add hsv() method to Imager::Color
275 Thanks to Leolo (Philip Gwyn)
276 https://rt.cpan.org/Ticket/Display.html?id=65385
278 - split libt1 Type 1 font support into a sub-module
279 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
281 - add a preload() class method for use in forking servers, and to
282 work around limitations in PAR.
283 https://rt.cpan.org/Ticket/Display.html?id=65665
287 - paletted writes to a masked image are now masked correctly.
288 Revealed by new coverage tests.
290 - update the filter plugin documentation.
291 https://rt.cpan.org/Ticket/Display.html?id=56513
293 - add the matrix() method to Imager::Matrix2d to allow creation of a
294 matrix with specified co-efficients. You can now multiple an
295 Imager::Matrix2d object by a 9 element array ref or a number.
296 https://rt.cpan.org/Ticket/Display.html?id=29938
298 - really fix loading TTF fonts with FT2 when FT1 isn't available.
299 Thanks to Leolo (Philip Gwyn)
300 https://rt.cpan.org/Ticket/Display.html?id=65386
301 https://rt.cpan.org/Ticket/Display.html?id=62855
303 - make sure each test script that needs testout/ creates it.
304 https://rt.cpan.org/Ticket/Display.html?id=65088
306 - handle a slightly different warning from libtiff 4.x
307 https://rt.cpan.org/Ticket/Display.html?id=65268
309 - the sat transform2() op returned an incorrect saturation.
310 https://rt.cpan.org/Ticket/Display.html?id=65391
312 Imager 0.80 - 17 Jan 2011
315 - added coverage tests for Imager::Fountain and Imager::Color::Float
317 - Imager is now maintained in git
318 http://git.imager.perl.org/imager.git
319 git://git.imager.perl.org/imager.git
323 - images with an translucent alpha channel were not scaled correctly
324 by the default (qtype=normal) scaling method.
325 https://rt.cpan.org/Public/Bug/Display.html?id=63922
327 - Imager::Color::Float now translates "#FFFFFF" to white instead of
328 just a little darker.
330 - make the default color map build algorithm "mediancut". This
331 changes the default color map builder for writing GIFs back to what
332 it was in 0.77, reverting a performance regression.
333 https://rt.cpan.org/Ticket/Display.html?id=64785
335 - handle failure to create a masked image correctly
337 Imager 0.79 - 10 Dec 2010
340 - add Imager::Test to the POD coverage tests and document the missing
343 - the convert() method now optimizes the case where all output
344 channels are either 0, sourced from a single input channel or 1.
345 This significantly speeds up presets like "addalpha", "green".
346 https://rt.cpan.org/Ticket/Display.html?id=51254
348 - add wiggle.pl sample, as suggested by Dan Oppenheim.
350 - add the combine() method to combine channels from multiple source
351 images into a new image
352 https://rt.cpan.org/Ticket/Display.html?id=11872
356 - treat the co-efficients for convert() as doubles instead of floats.
358 - If a higher (earlier) priority font handler failed to load, that
359 would crash preventing loading of later font handlers.
360 https://rt.cpan.org/Ticket/Display.html?id=62855
362 - parse defines from the options returned by pkg-config --cflags
363 https://rt.cpan.org/Ticket/Display.html?id=63223
365 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
366 included in the tarball. They are now included.
368 Imager 0.78 - 4 Oct 2010
373 - don't access deprecated members of the png_structp.
374 https://rt.cpan.org/Ticket/Display.html?id=60242
376 - document that using color objects is faster than supplying colors
378 https://rt.cpan.org/Ticket/Display.html?id=61047
380 - Imager::Probe now accepts array references for incpath and libpath.
381 https://rt.cpan.org/Ticket/Display.html?id=60244
383 Imager 0.77_02 - 27 Sep 2010
386 - moved Win32, FreeType 2 font support into sub-modules.
387 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
388 Uses Imager::Probe now.
389 https://rt.cpan.org/Public/Bug/Display.html?id=61328
391 - tested successfully with jpeg-8b
392 https://rt.cpan.org/Ticket/Display.html?id=60221
396 - from _01: look for missing file support test files in the right
399 - flood_fill() wouldn't fill the right side of a single scan-line
401 Thanks to Nicolas Roggli for reporting this.
403 - flood_fill wouldn't fill to the left edge of the image if the
404 starting line didn't reach the left edge.
405 Thanks to Nicolas Roggli for reporting this.
407 Imager 0.77_01 - 13 Sep 2010
410 - add each library-directory/pkgconfig/ to the pkg-config search path
412 Thanks to Justin Davis.
413 https://rt.cpan.org/Ticket/Display.html?id=60491
415 - moved GIF, TIFF, JPEG file handling code into sub-modules in
416 preparation for separate distribution.
417 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
419 - optimize filled box drawing (color, not fill)
423 - Imager::Probe was calling ExtUtils::Liblist to initialize
424 LD_RUN_PATH supplying an undefined value rather than the found
425 directory. Thanks to Justin Davis.
426 https://rt.cpan.org/Ticket/Display.html?id=60491
428 - only prepend ./ to font filenames when passing them to T1Lib and
429 then only when it would use its search mechanisms.
430 https://rt.cpan.org/Ticket/Display.html?id=60509
432 - fix the cache check for the X rgb.txt loader. This is typically
433 used for color translation on Unix-like systems, and the fix
434 improves performance of supplying colors by name by about 80 times.
435 Test code that managed 3400 10x10 pixel boxes/second sped up to
438 - clarify that Imager doesn't write EXIF metadata to images.
439 https://rt.cpan.org/Ticket/Display.html?id=60637
441 - Imager::Probe can now search subdirectories under its include path.
442 Used by the PNG Makefile.PL to find headers and libraries when they
443 aren't in the base directory, as in cygwin.
444 https://rt.cpan.org/Ticket/Display.html?id=60635
446 Imager 0.77 - 11 Aug 2010
449 I don't want Imager::File::PNG indexed as part of Imager, but forgot
450 to update the META.yml before updating the version.
452 - don't index Imager::File::PNG as part of Imager
454 - add resources to META.yml
456 Imager 0.76 - not released
461 - the align_string() method would ignore a string of "0" due to a
463 Thanks to Maurice Height for reporting this.
464 https://rt.cpan.org/Ticket/Display.html?id=60199
466 Imager 0.75_03 - 09 Aug 2010
471 - read_types() and write_types() would include png when it wasn't
472 available due to a problem with the %formats tie
474 - handle dependent libraries correctly (eg -lpng requiring -lz) in
475 the code run phase of library probing.
477 Imager 0.75_02 - 07 Aug 2010
482 - add file missing from MANIFEST, which was causing TIFF failures.
484 Imager 0.75_01 - 06 Aug 2010
487 Test release for the new PNG probe.
489 - added the ability to read multiple-image PNM files.
490 Note that unlike the pbm/pgm/ppm specification this accepts mixed
491 format files and allows white space padding between files.
492 Thanks to Philip Gwyn (Leolo) for this patch.
494 - moved the PNG file handling code into a sub-module in preparation
495 for separate distribution.
496 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
497 Also helps avoid complications from -I/-L compile/link options from
502 - Imager->new(data => $data) didn't try to process image file data in
504 https://rt.cpan.org/Ticket/Display.html?id=58761
506 - t/t50basicoo.t no longer depends on the other tests to generate its
508 https://rt.cpan.org/Ticket/Display.html?id=9798
509 Also, it wasn't testing pnm (pnm vs ppm mix-up)
511 - update the documentation of hardinvert to match the change in 0.62.
512 https://rt.cpan.org/Ticket/Display.html?id=59785
514 - added hardinvertall filter which also inverts the alpha channel
517 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
518 the probe can find the library for the test run.
519 https://rt.cpan.org/Ticket/Display.html?id=57518
521 Imager 0.75 - 20 Jun 2010
524 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
529 - an opacity fill based on a fountain fill would segfault when
530 filling an 8-bit/sample image.
532 - merge thickline branch polygon fix
533 https://rt.cpan.org/Ticket/Display.html?id=43518
535 Imager 0.74 - 7 May 2010
540 - read_multi() didn't handle a missing file format library correctly,
541 aborting on failing to call i_readgif_multi_wiol() or
542 i_readtiff_multi_wiol().
544 - fix spelling errors patched by Debian
545 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
547 - add an (unshipped) author test to spellcheck Imager's POD.
549 - update the TIFF file format documentation
550 https://rt.cpan.org/Ticket/Display.html?id=56510
552 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
554 Imager 0.73 - 15 Mar 2010
557 - implement outline circles, both anti-aliased and not
558 https://rt.cpan.org/Ticket/Display.html?id=19755
560 - a combine => "none" fill to a 1 or 3 channel image would produce
561 the incorrect colour.
563 Imager 0.72 - 09 Dec 2009
566 Bump version for release, since 0.71_03 is stable with CPAN testers.
568 Imager 0.71_03 - 5 Dec 2009
571 - further adjust the threads test so it only performs the tests on
572 perls where it's expected to work, and only if the threads module
575 Imager 0.71_02 - 1 Dec 2009
578 - adjust the way we load the threads module for the threads test so
579 it works with non-threaded perls
581 Imager 0.71_01 - 30 Nov 2009
586 - use scanline oriented operations to flip images instead of pixel
588 https://rt.cpan.org/Ticket/Display.html?id=39278
590 - use double/sample operations to flip large sample images instead of
591 8-bit sample operations.
592 https://rt.cpan.org/Ticket/Display.html?id=39280
595 https://rt.cpan.org/Ticket/Display.html?id=51874
597 - prevent double-frees when someone creates Imager objects and then
598 creates a thread. Note: this just handles some simple cases,
599 Imager doesn't support perl threads, and isn't likely to.
600 https://rt.cpan.org/Ticket/Display.html?id=52268
602 Imager 0.71 - 16 Nov 2009
605 - add the opacity fill type - an adaptor that modifies the opacity of
610 - the conv filter now enforces that the sum of the coefficients is
611 non-zero. Also, rather than skipping pixels off the edge off the
612 edge of the image, the closest edge pixel is used. Previously
613 dividing by the zero sum of coefficients could cause invalid
614 results or runtime exceptions.
615 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
618 Imager 0.70 - 21 Sep 2009
623 - release image row and comments memory on all error returns in gif
626 - handle zero length extensions, previously this would cause a null
628 Thanks to Krzysztof Wojtaś for the test data and fix for this.
630 - an integer division meant that preview scaling to below 1 pixel
631 wide or high (which isn't too useful anyway) was calculating using
632 NaNs on most platforms, and causing an exception on others.
633 Thanks to David Cantrell for producing a backtrace of the crash on
634 his Alpha-NetBSD CPAN test box which made it possible to track this
637 Imager 0.69 - 08 Sep 2009
642 - broken test fix - was attempting to call a function skip_all, when
643 that should be a parameter to plan().
645 - briefly document apidocs.perl, the tool used to build
646 Imager::APIRef and make some minor enhancements
648 - various minor documentation enhancements and fixes.
650 Imager 0.68 - 07 Sep 2009
653 - Imager->new(file => $filename) and other similar incantations will
655 https://rt.cpan.org/Ticket/Display.html?id=48261
659 - avoid using CHECK as a label in Imager::Test
660 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
662 - re-work most image file test files that require a library into
663 separate library present/not present files to remove stupidly long
666 - don't treat rubthrough() outside the bounds of the target image as
668 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
670 Imager 0.67_01 - 02 Sep 2009
675 - correct documentation of default of raw image interleave read
677 https://rt.cpan.org/Ticket/Display.html?id=42074
679 - add raw_ prefix to raw read parameters, though the original names
682 - fail the read if an invalid raw_interleave parameter is supplied
684 - warn if no interleave or raw_interleave parameter is supplied,
685 since the documented default was wrong, and incompatible with the
688 - for reading raw images, if raw_storechannels > raw_datachannels,
689 set the extra channels in the image to 0
691 - when probing for executables like freetype-config, search for .bat
692 and .cmd on MSWin32, as well as .exe.
693 https://rt.cpan.org/Ticket/Display.html?id=49275
695 - re-work the external libraries section of README:
696 - list Debian and Redhat package names for each library
700 - use the new EU::MM META_MERGE facility instead of generating
701 META.yml from scratch
702 https://rt.cpan.org/Ticket/Display.html?id=47888
704 - use Devel::CheckLib (bundled, modified) to check which release of
705 libtiff is installed and reject 3.9.0
706 http://bugzilla.maptools.org/show_bug.cgi?id=2088
707 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
709 Imager 0.67 - 12 Dec 2008
714 - fix a packaging error
716 Imager 0.66 - 12 Dec 2008
719 - 24-bit color .ICO/.CUR files can now be read.
723 - an optimization skipping 0 src alpha values could cause the
724 rubthrough() to read past the end of a buffer.
725 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
727 - corrected a reference leak where writing GIFs would leak memory.
728 This could also happen calling to_paletted().
729 Also documented the underlying long existing feature where the
730 colors parameter is filled with the generated color table and added
732 http://rt.cpan.org/Ticket/Display.html?id=41028
734 - write out the image size in bytes field of a BMP correctly.
735 http://rt.cpan.org/Ticket/Display.html?id=41406
737 - add limited tests for Imager::ExtUtils
739 - make Imager::ExtUtils->includes use an absolute path, since
740 a relative path could cause failures using Inline::C.
741 http://rt.cpan.org/Ticket/Display.html?id=37353
743 - re-arrange the POD for Imager::Font::BBox:
744 - mark total_width(), pos_width(), end_offset() obsolete, since
745 they're mostly for backwards compatibility
746 - group width methods and height methods
747 https://rt.cpan.org/Ticket/Display.html?id=39999
749 Imager 0.65 - 20 May 2008
754 - In some cases when an error occurs reading those parts of a JPEG
755 file after the image the scan-line buffer could be freed a second
756 time. In cases where the the error occured while reading the image
757 data it's possible that the buffer could have leaked.
758 Thanks to Gabriel Vasseur for reporting this and help in tracking
761 - the gif_screen_height tag was overriding the screen width and being
762 ignored for the screen height when present.
763 https://rt.cpan.org/Public/Bug/Display.html?id=35568
765 Imager 0.64 - 23 April 2008
768 This is a bug fix release. This includes a fix for a possible
773 - Possible security issue: The floating point sample path for image
774 based fills had a buffer overflow. This would overwrite the end of
775 a malloc()ed buffer with double precision floats.
776 http://rt.cpan.org/Ticket/Display.html?id=35324
779 - check that the result of fileno($fh) is defined rather than simply
780 true when read() or write() is supplied with an fh parameter.
781 http://rt.cpan.org/Ticket/Display.html?id=35139
783 - i_scale_axis() wasn't checking the result of i_img_new_ch()
784 resulting in a SIGSEGV when attempting to scale an image to a size
785 too large to fit in memory. This is a NULL pointer access issue,
786 not a buffer overflow.
787 Added a check for the failure.
788 scale_calculate() (and hence scale()) will now fail if any of the
789 scale size parameters are a reference.
790 http://rt.cpan.org/Ticket/Display.html?id=35172
792 - Regression: filling a greyscale image with a hatch used the wrong
793 color channels from the supplied fg/bg colors.
794 https://rt.cpan.org/Ticket/Display.html?id=35278
796 - fixed a related problem for image fills.
798 Imager 0.63 - 7 April 2008
801 This release primarily contains changes to improve ease of use -
802 rather than you having to convert images to the appropriate number of
803 channels, Imager handles it internally. How to handle drawing colors
804 and the default combine mode is a thornier problem left for some other
807 - the font libraries are now only initialized when needed.
808 http://rt.cpan.org/Ticket/Display.html?id=28825
810 - moved the imtoc.perl code into Imager::Preprocess
812 - paste() and rubthrough() now adapt the source image data to the
813 destination, so you can now safely paste/rubthrough from greyscale
814 images to color images or back, or from alpha channel images to
815 noalpha channels or back.
816 https://rt.cpan.org/Ticket/Display.html?id=30908
818 - rubthrough() now falls back to pasting when the source doesn't have
819 an alpha channel. This effectively treats the source as having a
820 max alpha channel, the right thing to do.
821 http://rt.cpan.org/Ticket/Display.html?id=29944
823 - re-worked most of the area filling code to use a common set of
824 functions when filling.
825 Corrected normal combine mode.
826 Rewrote most of the combine modes to match the way the SVG draft
827 defines them with respect to a translucent source and destination.
828 Added tests for translucent source and destination.
829 Added tests to check 8-bit/sample and double/sample combines work
831 https://rt.cpan.org/Ticket/Display.html?id=29879
833 - writing a 2 or 4 channel image to a JPEG file will now write that
834 image as if composited against a background, black by default,
835 overridable with the i_background tag/parameter.
836 https://rt.cpan.org/Ticket/Display.html?id=29876
838 - writing a 2 or 4 channel image to a PGM/PPM file will now write
839 that image as if composited against a background, black by default,
840 overridable with the i_background tag/parameter.
841 http://rt.cpan.org/Ticket/Display.html?id=30074
843 - writing a 2 or 4 channel image to a BMP file will now write that
844 image as if composited against a background, black by default,
845 overridable with the i_background tag/parameter.
846 http://rt.cpan.org/Ticket/Display.html?id=30075
850 - Imager::Matrix2d->translate() now only requires one of the x or y
852 http://rt.cpan.org/Ticket/Display.html?id=29937
854 - mixing qtype scaling now sets all channels of a pixel to zero if
855 the pixel has zero coverage (zero alpha). This should produce more
856 compressible output files.
857 http://rt.cpan.org/Ticket/Display.html?id=32324
859 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
861 https://bugzilla.redhat.com/show_bug.cgi?id=166254
862 I'm not changing the #! lines of the sample code, since it's sample
863 code, not intended for installation.
864 http://rt.cpan.org/Ticket/Display.html?id=33408
866 - some TGA images weren't being detected correctly as TGA images
867 https://rt.cpan.org/Ticket/Display.html?id=32925
869 - handling of the left-over bit for 16-bit/pixel TGA images has been
870 changed to match the behaviour of the GIMP. Previously the bit
871 being set was treated as an opaque pixel, but one user reported a
872 problem with loading such an image. I haven't been able to find any
873 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
874 I'll match it's behaviour. See issue 114913 in the GIMP's
876 http://rt.cpan.org/Ticket/Display.html?id=32926
878 Imager 0.62 - 10 December 2007
881 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
882 to /path under your home directory.
883 http://rt.cpan.org/Ticket/Display.html?id=29484
885 - the old dynaload code used Mach API functions to load dynamic
886 libraries on Mac OS X. These APIs have been deprecated in OS X
887 10.5 and were causing some build problems.
888 So henceforth Imager uses the dlopen() family of functions, and you
889 will need version 10.3 or later of OS X.
891 - added the det() function to the transform2() engine.
892 added the sample quad_to_square.pl
893 Courtesy Richard Fairhurst.
894 http://rt.cpan.org/Ticket/Display.html?id=31244
898 - samples/gifscale.pl sourced the base value for gif_top from
900 Thanks to Eleneldil G. Arilou for pointing this out.
902 - t/t82inline.t no longer loads B at runtime, to work around a bug
903 in some 5.005_0[45] installations.
904 http://rt.cpan.org/Ticket/Display.html?id=30508
906 - work around Module::Depends::Intrusive bug #21229
907 http://rt.cpan.org/Ticket/Display.html?id=30520
909 - the hardinvert filter no-longer inverts the alpha channel.
910 http://rt.cpan.org/Ticket/Display.html?id=30002
912 - the hardinvert filter now supports large samples
914 Imager 0.61_02 - 28 November 2007
917 - major TIFF support re-work
918 http://rt.cpan.org/Ticket/Display.html?id=20329
920 - added a C level image interface for accessing samples from 1-32
921 bits, exposed this at the perl level in getsamples()
923 - the conv filter now works at floating point precision for high bit
926 - added is_bilevel method to test whether an image should be written as
927 a bilevel image if the image format supports it.
929 - added -log-stderr as an Imager import list option
931 - added some important types to Imager::APIRef
933 - added test_image_double() to Imager::Test
937 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
940 - the scale() method with qtype mixing now handles images with an
941 alpha channel correctly.
943 - fixed a broken link from the "animated GIF" entry in the concept index.
944 Thanks to Slaven Rezic.
945 http://rt.cpan.org/Ticket/Display.html?id=30889
947 - on some perl's the infix expression parser test would fail due to
948 actions in the grammar returning false. Made sure all actions return
950 Thanks to Richard Fairhurst for spending a lot of time in tracking
952 http://rt.cpan.org/Public/Bug/Display.html?id=29562
954 Imager 0.61 - 5 November 2007
957 - added samples/gifscale.pl, which adjusts the screen size/position tags
958 when scaling an animated gif
959 http://rt.cpan.org/Ticket/Display.html?id=27591
963 - correct handling of sz in matrix_transform() - this should allow
964 perspective type transformations to work now.
965 http://rt.cpan.org/Ticket/Display.html?id=29936
967 - prevent a cast to integer warning on x64 builds in datatypes.c
968 also fixed some other type warnings
969 https://rt.cpan.org/Ticket/Display.html?id=30204
971 - some sub-directory tests depended on files produced by the parent
973 http://rt.cpan.org/Ticket/Display.html?id=30203
975 - Imager::Font::Wrap doesn't correctly set savepos
976 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
977 http://rt.cpan.org/Ticket/Display.html?id=29771
979 - test 171 in t/t01introvert.t was failing on perls configured to
981 http://rt.cpan.org/Ticket/Display.html?id=29413
983 - the code for the transform2() uminus operator was missing a break.
984 Added tests for better code coverage of the ops.
985 http://rt.cpan.org/Ticket/Display.html?id=29296
987 - the SGI RLE compression code could overflow its compression buffer
988 http://rt.cpan.org/Ticket/Display.html?id=30334
990 - the 32-bit output function used by the SGI code only handled values
991 under 0x10000. This was most noticable when writing large RLE images.
992 http://rt.cpan.org/Ticket/Display.html?id=30335
994 - validate chan_count for chans == NULL for each of the i_gsamp()
996 http://rt.cpan.org/Ticket/Display.html?id=28985
998 - attempt to work around the test failure at
999 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
1000 http://rt.cpan.org/Ticket/Display.html?id=29562
1002 - improve the error messages produced when attempting to read or write
1003 an unknown image file format.
1004 http://rt.cpan.org/Ticket/Display.html?id=30103
1006 - improve the transform2() documentation
1007 http://rt.cpan.org/Ticket/Display.html?id=29267
1009 - correctly generate the author key in META.yml
1010 http://rt.cpan.org/Ticket/Display.html?id=30377
1012 - correctly blend a rotated (or matrix_transformed()) image when
1013 performing interpolation in the presence of an alpha channel.
1014 Also corrected the centring of the rotated image on the output
1017 Imager 0.60 - 30 August 2007
1020 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
1021 now has full SGI RGB image format, including RLE and 16-bit/sample
1023 https://rt.cpan.org/Ticket/Display.html?id=8666
1025 - logging functions are now available in the API
1027 - applied Gabriel Vasseur's patch
1028 added documentation, further tests, and support for greyscale images
1029 Obviously problems are my fault :)
1030 https://rt.cpan.org/Ticket/Display.html?id=28142
1032 - the mask for ICO/CUR images is now applied as an alpha channel to
1033 the returned image. For the old behaviour, supply ico_masked => 0
1034 to read() or read_multi(). This should be less confusing when
1035 using Imager as a general image processor.
1036 https://rt.cpan.org/Ticket/Display.html?id=29001
1040 - in some cases it's possible for giflib/libungif to return color
1041 indexes outside the range of colors defined by the image's palette.
1042 We now expand the palette to match the indexes used.
1043 Thanks to Gabriel Vasseur for reporting this.
1045 - fixed various memory leaks that could occur when failing to read png,
1046 jpeg, bmp or tga files.
1048 - to avoid confusion, channels not present in the image are returned as
1049 zero by getscanline(). This has no effect on the C level i_glin()
1050 and i_glinf() API functions which continue to not set the unused
1053 - the convert() method now returns an image of the same sample size as
1055 https://rt.cpan.org/Ticket/Display.html?id=28492
1057 - remove repeated text in Imager::Files
1058 http://rt.cpan.org/Ticket/Display.html?id=27589
1060 - be even more explicit that scale() and friends don't modify the source
1061 image, but return a new image.
1062 http://rt.cpan.org/Ticket/Display.html?id=28570
1064 - improve the error message from errstr() when you try to load a font
1065 for which the driver hasn't been built in Imager.
1066 http://rt.cpan.org/Ticket/Display.html?id=27571
1068 - transparency is now enabled by default when writing GIF images
1069 http://rt.cpan.org/Ticket/Display.html?id=27615
1071 - Imager would not load on Windows 98
1072 http://rt.cpan.org/Ticket/Display.html?id=27653
1074 Imager 0.59 - 14 June 2007
1079 - fixes a regression introduced by the fixes for RT 11972
1080 http://rt.cpan.org/Ticket/Display.html?id=27546
1082 - cropping outside the image would return an Imager object with
1083 no low-level image object, instead of returning false.
1084 Fixed by: Philip Gwyn (Leolo)
1085 http://rt.cpan.org/Ticket/Display.html?id=27509
1087 Imager 0.58 - 16 May 2007
1090 No significant changes from 0.57_01.
1092 Imager 0.57_01 - 11 May 2007
1095 - added to_rgb16 to produce a 16-bit/sample version of an image
1097 - improve freetype 1.x text output efficiency
1101 - search another place for rgb.txt, and check all the places
1102 Imager::Color checks when deciding whether to skip testing it
1103 http://rt.cpan.org/Ticket/Display.html?id=26064
1105 - use a convolution kernel size based on the stddev rather than a
1106 fixed size when performing a gaussian blur
1107 http://rt.cpan.org/Ticket/Display.html?id=25645
1109 - document the difference() method's mindist parameter, and debug it.
1111 - put the Imager release number in the Inline::C generated code to
1112 regenerate Inline code when a new release of Imager is installed.
1113 http://rt.cpan.org/Ticket/Display.html?id=26278
1115 - fix rendering on alpha channel images for the FreeType 1.x driver.
1116 http://rt.cpan.org/Ticket/Display.html?id=11972
1118 - fix rendering on alpha channel images for the T1lib driver.
1119 http://rt.cpan.org/Ticket/Display.html?id=11972
1121 - reworked library probing, we can now set more than one probe
1122 function for a library. Disabled the default (non-freetype-config)
1123 library probe and added an extra probe function that searches for
1124 both ft2build.h and whatever it includes, and adds -I as needed.
1125 Hopefully this will fix build problems like
1126 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
1127 http://rt.cpan.org/Ticket/Display.html?id=26086
1129 Imager 0.57 - 30 Apr 2007
1132 This is a maintenence release fixing a security issue in Imager.
1134 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
1135 overflow in malloced memory. There will be further discussion of
1136 this issue in the ticket below.
1137 http://rt.cpan.org/Ticket/Display.html?id=26811
1138 CVE-2007-2459 CVE-2007-2413
1139 The descriptions at cve.mitre.org varied in quality, please see the
1140 ticket at rt.cpan.org for a more accurate description of the issue.
1142 Imager 0.56 - 1 Apr 2007
1145 - added support for reading 16-bit/sample PGM/PPM images
1147 - added support for writing 16-bit/sample PGM/PPM images
1149 - improved performance of reading PBM/PGM/PPM images
1151 - added support for writing PBM images if the image is paletted and
1152 contains only black and white
1154 - added a new make_colors value - "mono"
1156 - switched from the svn log Changes to a manual Changes to reduce
1159 - new sample code - samples/flasher.pl
1163 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
1164 was returning an image object with an extra reference, this
1165 resulted in a memory leak.
1166 http://rt.cpan.org/Ticket/Display.html?id=24992
1168 - fix rendering on alpha channel images for the FreeType 2.x driver
1169 http://rt.cpan.org/Ticket/Display.html?id=11972
1171 - reading bmp files now consitently handles short reads. You can now
1172 supply a parameter to treat a short read as successful and set
1174 http://rt.cpan.org/Ticket/Display.html?id=8426
1176 - previously, reading ASCII PBM files required spaces between samples,
1177 even though the format doesn't require that
1179 - improved documentation of the unsharpmask filter (I hope)
1180 http://rt.cpan.org/Ticket/Display.html?id=25531
1182 - force flushing of the output from i_tt_dump_names() and test output
1183 in t/t35ttfont.t to prevent output from being mixed up.
1184 https://rt.cpan.org/Ticket/Display.html?id=24859
1186 - rewrite a conditional expression as an if() to hopefully work around
1187 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
1188 https://rt.cpan.org/Ticket/Display.html?id=25561
1190 - avoid Data::Dumper in regops.perl to support older releases of perl
1191 https://rt.cpan.org/Ticket/Display.html?id=24391
1193 Imager 0.55 - 16 Dec 2006
1196 This is primarily a bug fix release.
1198 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1200 There is one new feature:
1202 - the Win32 font driver now supports UTF8 (RT 22166)
1203 http://www.cpanforum.com/threads/3276
1204 http://rt.cpan.org/Ticket/Display.html?id=22166
1206 Several bugs were fixed:
1208 - the string() method would not output the string "0"
1209 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1211 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1212 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1214 - the gif_disposal and gif_user_input tags weren't being read from
1216 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1218 - gif.c was failing to build under MSVC
1219 http://rt.cpan.org/Ticket/Display.html?id=23922
1221 - in some cases strings passed to the string() method were treated as
1222 terminated by NUL (chr 0)
1223 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1225 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1226 that's the default build name for zlib on Win32.
1227 http://rt.cpan.org/Ticket/Display.html?id=23064
1229 - search $Config{incpath} for headers too, which we should have been
1232 Win32 font driver fixes:
1234 - the global descent value from bounding box was the wrong sign
1235 http://www.cpanforum.com/threads/3276
1237 - if the first or last glyph overflowed the left or right side of the
1238 advance width they would be clipped
1241 Imager 0.54 - 14 Sep 2006
1244 This is primarily a feature release:
1246 - a new qtype value 'mixing' has been added to the scale()
1247 method. This is faster than 'normal', slower than 'preview'. This
1248 is based on the method used by pnmscale, and seems to produce less
1249 blurry results than normal.
1250 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1252 - the rubthrough() method can now render onto images with an alpha
1254 http://rt.cpan.org/Ticket/Display.html?id=20678
1256 - the read_multi() method now falls back to calling doing a single
1257 image read via the read() method and write_multi() will now fall
1258 back to calling write() if a single image is supplied. This means
1259 you can simply call the read_multi() or write_multi() functions
1260 without having to check if the type is formatted by that method.
1261 http://rt.cpan.org/Ticket/Display.html?id=19457
1262 http://rt.cpan.org/Ticket/Display.html?id=19458
1264 - the GIF loop extension can now be written. If you don't have
1265 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1267 http://rt.cpan.org/Ticket/Display.html?id=21185
1269 - getscanline() and setscanline() can now read/write palette index
1270 based data from/to the image for paletted images, by setting type to
1272 http://rt.cpan.org/Ticket/Display.html?id=20338
1274 - we no longer hassle you to disable GIF support
1275 http://rt.cpan.org/Ticket/Display.html?id=20687
1277 - minor documentation fixes
1280 Imager 0.53 - 26 Jul 2006
1283 This is a bugfix release.
1285 Some test code was left in a code path not covered by the test

1326 inverted CMYK that photoshop (and Corel for example) produce into RGB.
