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 - fix combine=0 fill color anti-aliasing on the double/sample path
12 https://rt.cpan.org/Ticket/Display.html?id=71309
14 - make default text color non-transparent
15 https://rt.cpan.org/Ticket/Display.html?id=71469
17 - apply the last of the Debian unforwarded spelling fixes
18 https://rt.cpan.org/Ticket/Display.html?id=70656
20 - the log() method used its message parameter as a C level format
22 https://rt.cpan.org/Ticket/Display.html?id=71653
24 Imager 0.85_01 - 10 Oct 2011
27 - add simple tests for the Imager::Test test_image generators
29 - io_glue I/O buffering re-work:
31 - reorganize io_glue to do it's own buffering by default
33 - the unbuffered functions are available as i_io_raw_read() (or
34 raw_read() from perl) etc but are not recommended for typical
37 - use the new i_io_peekn() when checking for file magic to avoid
38 seek, allowing Imager to detect the file type and read the file
39 from an unseekable stream (for formats that don't use random
42 - added several new I/O layer API functions.
44 - fix the TGA performance problem, most noticably on Win32
45 https://rt.cpan.org/Ticket/Display.html?id=70037
47 - TIFF now uses wrapper functions of the correct types to avoid casts
48 https://rt.cpan.org/Ticket/Display.html?id=69912
50 - the callback IO object did its own buffering, controlled by the
51 maxbuffer parameter supplied to the read() and write() methods.
52 This buffering has been removed, to avoid redundancy with the
53 common io_glue buffering. This also avoids a bug in that code
54 which could rarely pass a zero length to the read callback and
55 then panic about the result.
57 - the callback IO object now tests the result of calling the close
58 callback, which should return true for success.
60 - the PNM reader did its own buffering. This buffering has been
61 removed to avoid redundancy with the common io_glue buffering.
63 - previously the read handlers for fd and callback I/O layers would
64 call the underlying interface (POSIX read or your supplied callback)
65 until it filled the buffer. It now only makes one call.
67 - added public constructors for I/O layer objects (see Imager::IO)
69 - all core file handlers now use the i_io_foo() wrappers to gain
70 access to buffered I/O rather than calling the I/O layer
73 - all core file handlers now check for error on close.
75 - Backward compatibility: if you hava custom file handlers, you can
76 use i_io_write() etc since they're available as macros in older
79 - eliminate the final remnants of io_glue_commit_types().
81 - bump IMAGER_API_VERSION, since the above may break assumptions.
83 - removed the long unused i_gen_reader() and i_gen_writer() utility
86 Imager 0.85 - 29 Aug 2011
89 The main changes in the release versus 0.84 are:
91 - on 64-bit systems, 64-bit types are consistently used for image
92 dimensions and co-ordinated, and for memory block sizes.
94 - handle IFD loops in TIFF files correctly. Previously this would
95 lead to an infinite loop.
99 - fix the link in the getheight() entry in the method index
101 Imager 0.84_02 - 22 Aug 2011
104 Development release, this will become 0.85 if CPAN testers is
109 - the image file limits set by set_file_limits() weren't being
110 checked when reading TIFF files.
111 https://rt.cpan.org/Ticket/Display.html?id=69915
113 - Provide more information about file format module load errors on a
114 failed image file read() or write().
115 https://rt.cpan.org/Ticket/Display.html?id=69194
117 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
118 through TIFF images, since it checks for IFD loops.
119 https://rt.cpan.org/Ticket/Display.html?id=69914
121 - don't leak memory when out of range palette indexes are supplied to
123 https://rt.cpan.org/Ticket/Display.html?id=69242
125 - require a later version of CPAN::Meta to ensure JSON::PP and
126 CPAN::Meta::YAML are available.
127 https://rt.cpan.org/Ticket/Display.html?id=69008
129 - hoist the per-line calculations for the flines implementations, and
130 modernize the tests a bit.
131 https://rt.cpan.org/Ticket/Display.html?id=70126
133 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
135 https://rt.cpan.org/Ticket/Display.html?id=69147
137 - if t1lib failed to reinitialize it would be left as marked
139 https://rt.cpan.org/Ticket/Display.html?id=69877
141 - update the bundled (and still modified) Devel::CheckLib
142 https://rt.cpan.org/Ticket/Display.html?id=69170
144 Imager 0.84_01 - 8 Aug 2011
147 Development release as a sanity check for the types re-work.
149 Massive types re-work:
151 - the type used internally for pixel co-ordinates and image sizes is
152 now 64-bit on 64-bit platforms (at least sane ones).
154 - size_t is now used consistently for memory block sizes.
156 - since this changes the binary interface, the Imager API version has
157 been incremented. Any module that uses the API will need to be
158 rebuilt. In most cases that will be enough, but calls to any APIs
159 that take a pointer to image sizes may need source changes.
161 - you should be able to create very large images on 64-bit systems,
162 if you have enough memory. Successfully created a 32768 x 49192 x
163 3 channel image, filled with a tiled image and scaled it. The
164 unscaled image was also successfully saved to a JPEG.
166 - check the image size before attempting to write BMP, GIF, JPEG,
167 PNG, SGI, TGA, TIFF images.
169 - correctly handle reading TGA images over 32767 pixels wide or tall.
173 - the gif_left and gif_top tags are now clamped to non-negative
174 values when writing a GIF image.
176 - removed dead callback read/write code
178 The default maximum memory size when reading files is now 1G.
180 Imager 0.84 - 20 Jun 2011
183 - Imager no longer inherits from Exporter (unless you're running an
186 - Imager can now write progressive JPEGs (it could always read them).
187 https://rt.cpan.org/Ticket/Display.html?id=68691
191 - re-work, document and test Imager's logging facility.
192 https://rt.cpan.org/Ticket/Display.html?id=65227
194 - fix META.yml testing and the generated META.yml
195 https://rt.cpan.org/Ticket/Display.html?id=65235
197 - test and add error reporting to to_*() family methods
199 - add to_rgb_double() method.
200 https://rt.cpan.org/Ticket/Display.html?id=65101
202 - Imager no longer exports anything by default
203 https://rt.cpan.org/Ticket/Display.html?id=65228
205 - convert colors to grayscale if the supplied (or generated) palette
206 contains only grays when performing error diffusion color
208 https://rt.cpan.org/Ticket/Display.html?id=68508
210 - writing a paletted image to GIF wouldn't always use the colors
211 supplied (or generated, eg. via make_colors => "mono"), which was
213 https://rt.cpan.org/Ticket/Display.html?id=67912
215 - replace (imager|tony)@imager.perl.org in the doc, since I don't
216 plan to continue receiving mail at that address.
217 https://rt.cpan.org/Ticket/Display.html?id=68591
219 Imager 0.83 - 21 May 2011
224 - diag() the error message on failure for some TIFF tests that are
225 failing on a Solaris smoker.
226 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
228 Imager 0.82_01 - 17 May 2011
231 Dev release, in case the compose tests are too sensitive.
235 - Imager::Font::T1 incorrectly checked for absolute filename under
236 Win32. Thanks to kmx for the report and fix.
237 https://rt.cpan.org/Ticket/Display.html?id=67963
239 - compose() with the target, source or mask position off the top or
240 left of the target image didn't clip the source image correctly.
241 https://rt.cpan.org/Ticket/Display.html?id=67220
243 - compose() now returns a useful error message on a non-positive
246 - compose.im now at 100% test coverage. (As opposed to, umm, much,
249 Imager 0.82 - 14 Mar 2011
254 - eliminate calls to i_has_format() from the test suite, since it's
255 no longer a useful way to check for file format support. Eliminate
256 i_has_format() from the functions exposed via XS.
257 https://rt.cpan.org/Ticket/Display.html?id=65863
259 - eliminate calls to note(), which isn't in the (very old) version of
260 Test::More we have as a pre-requisite. note() is modern enough
261 that I don't feel a need to require a Test::More upgrade for it.
262 https://rt.cpan.org/Ticket/Display.html?id=65864
264 - skip the threads tests on Test::More 2.00_*
265 https://rt.cpan.org/Ticket/Display.html?id=65812
267 - add an (unshipped) test to check Imager's internal POD links
268 https://rt.cpan.org/Ticket/Display.html?id=65749
270 - improve the library detection summary
271 https://rt.cpan.org/Ticket/Display.html?id=9675
273 - increase the version of Imager::Font::Type1 so that upgrades don't
274 downgrade the version in this file.
275 https://rt.cpan.org/Ticket/Display.html?id=66250
277 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
278 that option for the directories that would normally go in
279 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
280 https://rt.cpan.org/Ticket/Display.html?id=65955
282 Imager 0.81 - 14 Feb 2011
285 - added coverage tests for masked images (maskimg.c @100% test coverage)
287 - add hsv() method to Imager::Color
288 Thanks to Leolo (Philip Gwyn)
289 https://rt.cpan.org/Ticket/Display.html?id=65385

295 work around limitations in PAR.
296 https://rt.cpan.org/Ticket/Display.html?id=65665
300 - paletted writes to a masked image are now masked correctly.
301 Revealed by new coverage tests.
303 - update the filter plugin documentation.
304 https://rt.cpan.org/Ticket/Display.html?id=56513
306 - add the matrix() method to Imager::Matrix2d to allow creation of a
307 matrix with specified co-efficients. You can now multiple an
308 Imager::Matrix2d object by a 9 element array ref or a number.
309 https://rt.cpan.org/Ticket/Display.html?id=29938
311 - really fix loading TTF fonts with FT2 when FT1 isn't available.
312 Thanks to Leolo (Philip Gwyn)
313 https://rt.cpan.org/Ticket/Display.html?id=65386
314 https://rt.cpan.org/Ticket/Display.html?id=62855
316 - make sure each test script that needs testout/ creates it.
317 https://rt.cpan.org/Ticket/Display.html?id=65088
319 - handle a slightly different warning from libtiff 4.x
320 https://rt.cpan.org/Ticket/Display.html?id=65268
322 - the sat transform2() op returned an incorrect saturation.
323 https://rt.cpan.org/Ticket/Display.html?id=65391
325 Imager 0.80 - 17 Jan 2011
328 - added coverage tests for Imager::Fountain and Imager::Color::Float
330 - Imager is now maintained in git
331 http://git.imager.perl.org/imager.git
332 git://git.imager.perl.org/imager.git
336 - images with an translucent alpha channel were not scaled correctly
337 by the default (qtype=normal) scaling method.
338 https://rt.cpan.org/Public/Bug/Display.html?id=63922
340 - Imager::Color::Float now translates "#FFFFFF" to white instead of
341 just a little darker.
343 - make the default color map build algorithm "mediancut". This
344 changes the default color map builder for writing GIFs back to what
345 it was in 0.77, reverting a performance regression.
346 https://rt.cpan.org/Ticket/Display.html?id=64785
348 - handle failure to create a masked image correctly
350 Imager 0.79 - 10 Dec 2010
353 - add Imager::Test to the POD coverage tests and document the missing
356 - the convert() method now optimizes the case where all output
357 channels are either 0, sourced from a single input channel or 1.
358 This significantly speeds up presets like "addalpha", "green".
359 https://rt.cpan.org/Ticket/Display.html?id=51254
361 - add wiggle.pl sample, as suggested by Dan Oppenheim.
363 - add the combine() method to combine channels from multiple source
364 images into a new image
365 https://rt.cpan.org/Ticket/Display.html?id=11872
369 - treat the co-efficients for convert() as doubles instead of floats.
371 - If a higher (earlier) priority font handler failed to load, that
372 would crash preventing loading of later font handlers.
373 https://rt.cpan.org/Ticket/Display.html?id=62855
375 - parse defines from the options returned by pkg-config --cflags
376 https://rt.cpan.org/Ticket/Display.html?id=63223
378 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
379 included in the tarball. They are now included.
381 Imager 0.78 - 4 Oct 2010
386 - don't access deprecated members of the png_structp.
387 https://rt.cpan.org/Ticket/Display.html?id=60242
389 - document that using color objects is faster than supplying colors
391 https://rt.cpan.org/Ticket/Display.html?id=61047
393 - Imager::Probe now accepts array references for incpath and libpath.
394 https://rt.cpan.org/Ticket/Display.html?id=60244
396 Imager 0.77_02 - 27 Sep 2010
399 - moved Win32, FreeType 2 font support into sub-modules.
400 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
401 Uses Imager::Probe now.
402 https://rt.cpan.org/Public/Bug/Display.html?id=61328
404 - tested successfully with jpeg-8b
405 https://rt.cpan.org/Ticket/Display.html?id=60221
409 - from _01: look for missing file support test files in the right
412 - flood_fill() wouldn't fill the right side of a single scan-line
414 Thanks to Nicolas Roggli for reporting this.
416 - flood_fill wouldn't fill to the left edge of the image if the
417 starting line didn't reach the left edge.
418 Thanks to Nicolas Roggli for reporting this.
420 Imager 0.77_01 - 13 Sep 2010
423 - add each library-directory/pkgconfig/ to the pkg-config search path
425 Thanks to Justin Davis.
426 https://rt.cpan.org/Ticket/Display.html?id=60491
428 - moved GIF, TIFF, JPEG file handling code into sub-modules in
429 preparation for separate distribution.
430 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
432 - optimize filled box drawing (color, not fill)
436 - Imager::Probe was calling ExtUtils::Liblist to initialize
437 LD_RUN_PATH supplying an undefined value rather than the found
438 directory. Thanks to Justin Davis.
439 https://rt.cpan.org/Ticket/Display.html?id=60491
441 - only prepend ./ to font filenames when passing them to T1Lib and
442 then only when it would use its search mechanisms.
443 https://rt.cpan.org/Ticket/Display.html?id=60509
445 - fix the cache check for the X rgb.txt loader. This is typically
446 used for color translation on Unix-like systems, and the fix
447 improves performance of supplying colors by name by about 80 times.
448 Test code that managed 3400 10x10 pixel boxes/second sped up to
451 - clarify that Imager doesn't write EXIF metadata to images.
452 https://rt.cpan.org/Ticket/Display.html?id=60637
454 - Imager::Probe can now search subdirectories under its include path.
455 Used by the PNG Makefile.PL to find headers and libraries when they
456 aren't in the base directory, as in cygwin.
457 https://rt.cpan.org/Ticket/Display.html?id=60635
459 Imager 0.77 - 11 Aug 2010
462 I don't want Imager::File::PNG indexed as part of Imager, but forgot
463 to update the META.yml before updating the version.
465 - don't index Imager::File::PNG as part of Imager
467 - add resources to META.yml
469 Imager 0.76 - not released
474 - the align_string() method would ignore a string of "0" due to a
476 Thanks to Maurice Height for reporting this.
477 https://rt.cpan.org/Ticket/Display.html?id=60199
479 Imager 0.75_03 - 09 Aug 2010
484 - read_types() and write_types() would include png when it wasn't
485 available due to a problem with the %formats tie
487 - handle dependent libraries correctly (eg -lpng requiring -lz) in
488 the code run phase of library probing.
490 Imager 0.75_02 - 07 Aug 2010
495 - add file missing from MANIFEST, which was causing TIFF failures.
497 Imager 0.75_01 - 06 Aug 2010
500 Test release for the new PNG probe.
502 - added the ability to read multiple-image PNM files.
503 Note that unlike the pbm/pgm/ppm specification this accepts mixed
504 format files and allows white space padding between files.
505 Thanks to Philip Gwyn (Leolo) for this patch.
507 - moved the PNG file handling code into a sub-module in preparation
508 for separate distribution.
509 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
510 Also helps avoid complications from -I/-L compile/link options from
515 - Imager->new(data => $data) didn't try to process image file data in
517 https://rt.cpan.org/Ticket/Display.html?id=58761
519 - t/t50basicoo.t no longer depends on the other tests to generate its
521 https://rt.cpan.org/Ticket/Display.html?id=9798
522 Also, it wasn't testing pnm (pnm vs ppm mix-up)
524 - update the documentation of hardinvert to match the change in 0.62.
525 https://rt.cpan.org/Ticket/Display.html?id=59785
527 - added hardinvertall filter which also inverts the alpha channel
530 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
531 the probe can find the library for the test run.
532 https://rt.cpan.org/Ticket/Display.html?id=57518
534 Imager 0.75 - 20 Jun 2010
537 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
542 - an opacity fill based on a fountain fill would segfault when
543 filling an 8-bit/sample image.
545 - merge thickline branch polygon fix
546 https://rt.cpan.org/Ticket/Display.html?id=43518
548 Imager 0.74 - 7 May 2010
553 - read_multi() didn't handle a missing file format library correctly,
554 aborting on failing to call i_readgif_multi_wiol() or
555 i_readtiff_multi_wiol().
557 - fix spelling errors patched by Debian
558 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
560 - add an (unshipped) author test to spellcheck Imager's POD.
562 - update the TIFF file format documentation
563 https://rt.cpan.org/Ticket/Display.html?id=56510
565 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
567 Imager 0.73 - 15 Mar 2010
570 - implement outline circles, both anti-aliased and not
571 https://rt.cpan.org/Ticket/Display.html?id=19755
573 - a combine => "none" fill to a 1 or 3 channel image would produce
574 the incorrect colour.
576 Imager 0.72 - 09 Dec 2009
579 Bump version for release, since 0.71_03 is stable with CPAN testers.
581 Imager 0.71_03 - 5 Dec 2009
584 - further adjust the threads test so it only performs the tests on
585 perls where it's expected to work, and only if the threads module
588 Imager 0.71_02 - 1 Dec 2009
591 - adjust the way we load the threads module for the threads test so
592 it works with non-threaded perls
594 Imager 0.71_01 - 30 Nov 2009
599 - use scanline oriented operations to flip images instead of pixel
601 https://rt.cpan.org/Ticket/Display.html?id=39278
603 - use double/sample operations to flip large sample images instead of
604 8-bit sample operations.
605 https://rt.cpan.org/Ticket/Display.html?id=39280
608 https://rt.cpan.org/Ticket/Display.html?id=51874
610 - prevent double-frees when someone creates Imager objects and then
611 creates a thread. Note: this just handles some simple cases,
612 Imager doesn't support perl threads, and isn't likely to.
613 https://rt.cpan.org/Ticket/Display.html?id=52268
615 Imager 0.71 - 16 Nov 2009
618 - add the opacity fill type - an adaptor that modifies the opacity of
623 - the conv filter now enforces that the sum of the coefficients is
624 non-zero. Also, rather than skipping pixels off the edge off the
625 edge of the image, the closest edge pixel is used. Previously
626 dividing by the zero sum of coefficients could cause invalid
627 results or runtime exceptions.
628 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
631 Imager 0.70 - 21 Sep 2009
636 - release image row and comments memory on all error returns in gif
639 - handle zero length extensions, previously this would cause a null
641 Thanks to Krzysztof Wojtaś for the test data and fix for this.
643 - an integer division meant that preview scaling to below 1 pixel
644 wide or high (which isn't too useful anyway) was calculating using
645 NaNs on most platforms, and causing an exception on others.
646 Thanks to David Cantrell for producing a backtrace of the crash on
647 his Alpha-NetBSD CPAN test box which made it possible to track this
650 Imager 0.69 - 08 Sep 2009
655 - broken test fix - was attempting to call a function skip_all, when
656 that should be a parameter to plan().
658 - briefly document apidocs.perl, the tool used to build
659 Imager::APIRef and make some minor enhancements
661 - various minor documentation enhancements and fixes.
663 Imager 0.68 - 07 Sep 2009
666 - Imager->new(file => $filename) and other similar incantations will
668 https://rt.cpan.org/Ticket/Display.html?id=48261
672 - avoid using CHECK as a label in Imager::Test
673 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
675 - re-work most image file test files that require a library into
676 separate library present/not present files to remove stupidly long
679 - don't treat rubthrough() outside the bounds of the target image as
681 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
683 Imager 0.67_01 - 02 Sep 2009
688 - correct documentation of default of raw image interleave read
690 https://rt.cpan.org/Ticket/Display.html?id=42074
692 - add raw_ prefix to raw read parameters, though the original names
695 - fail the read if an invalid raw_interleave parameter is supplied
697 - warn if no interleave or raw_interleave parameter is supplied,
698 since the documented default was wrong, and incompatible with the
701 - for reading raw images, if raw_storechannels > raw_datachannels,
702 set the extra channels in the image to 0
704 - when probing for executables like freetype-config, search for .bat
705 and .cmd on MSWin32, as well as .exe.
706 https://rt.cpan.org/Ticket/Display.html?id=49275
708 - re-work the external libraries section of README:
709 - list Debian and Redhat package names for each library
713 - use the new EU::MM META_MERGE facility instead of generating
714 META.yml from scratch
715 https://rt.cpan.org/Ticket/Display.html?id=47888
717 - use Devel::CheckLib (bundled, modified) to check which release of
718 libtiff is installed and reject 3.9.0
719 http://bugzilla.maptools.org/show_bug.cgi?id=2088
720 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
722 Imager 0.67 - 12 Dec 2008
727 - fix a packaging error
729 Imager 0.66 - 12 Dec 2008
732 - 24-bit color .ICO/.CUR files can now be read.
736 - an optimization skipping 0 src alpha values could cause the
737 rubthrough() to read past the end of a buffer.
738 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
740 - corrected a reference leak where writing GIFs would leak memory.
741 This could also happen calling to_paletted().
742 Also documented the underlying long existing feature where the
743 colors parameter is filled with the generated color table and added
745 http://rt.cpan.org/Ticket/Display.html?id=41028
747 - write out the image size in bytes field of a BMP correctly.
748 http://rt.cpan.org/Ticket/Display.html?id=41406
750 - add limited tests for Imager::ExtUtils
752 - make Imager::ExtUtils->includes use an absolute path, since
753 a relative path could cause failures using Inline::C.
754 http://rt.cpan.org/Ticket/Display.html?id=37353
756 - re-arrange the POD for Imager::Font::BBox:
757 - mark total_width(), pos_width(), end_offset() obsolete, since
758 they're mostly for backwards compatibility
759 - group width methods and height methods
760 https://rt.cpan.org/Ticket/Display.html?id=39999
762 Imager 0.65 - 20 May 2008
767 - In some cases when an error occurs reading those parts of a JPEG
768 file after the image the scan-line buffer could be freed a second
769 time. In cases where the the error occured while reading the image
770 data it's possible that the buffer could have leaked.
771 Thanks to Gabriel Vasseur for reporting this and help in tracking
774 - the gif_screen_height tag was overriding the screen width and being
775 ignored for the screen height when present.
776 https://rt.cpan.org/Public/Bug/Display.html?id=35568
778 Imager 0.64 - 23 April 2008
781 This is a bug fix release. This includes a fix for a possible
786 - Possible security issue: The floating point sample path for image
787 based fills had a buffer overflow. This would overwrite the end of
788 a malloc()ed buffer with double precision floats.
789 http://rt.cpan.org/Ticket/Display.html?id=35324
792 - check that the result of fileno($fh) is defined rather than simply
793 true when read() or write() is supplied with an fh parameter.
794 http://rt.cpan.org/Ticket/Display.html?id=35139
796 - i_scale_axis() wasn't checking the result of i_img_new_ch()
797 resulting in a SIGSEGV when attempting to scale an image to a size
798 too large to fit in memory. This is a NULL pointer access issue,
799 not a buffer overflow.
800 Added a check for the failure.
801 scale_calculate() (and hence scale()) will now fail if any of the
802 scale size parameters are a reference.
803 http://rt.cpan.org/Ticket/Display.html?id=35172
805 - Regression: filling a greyscale image with a hatch used the wrong
806 color channels from the supplied fg/bg colors.
807 https://rt.cpan.org/Ticket/Display.html?id=35278
809 - fixed a related problem for image fills.
811 Imager 0.63 - 7 April 2008
814 This release primarily contains changes to improve ease of use -
815 rather than you having to convert images to the appropriate number of
816 channels, Imager handles it internally. How to handle drawing colors
817 and the default combine mode is a thornier problem left for some other
820 - the font libraries are now only initialized when needed.
821 http://rt.cpan.org/Ticket/Display.html?id=28825
823 - moved the imtoc.perl code into Imager::Preprocess
825 - paste() and rubthrough() now adapt the source image data to the
826 destination, so you can now safely paste/rubthrough from greyscale
827 images to color images or back, or from alpha channel images to
828 noalpha channels or back.
829 https://rt.cpan.org/Ticket/Display.html?id=30908
831 - rubthrough() now falls back to pasting when the source doesn't have
832 an alpha channel. This effectively treats the source as having a
833 max alpha channel, the right thing to do.
834 http://rt.cpan.org/Ticket/Display.html?id=29944
836 - re-worked most of the area filling code to use a common set of
837 functions when filling.
838 Corrected normal combine mode.
839 Rewrote most of the combine modes to match the way the SVG draft
840 defines them with respect to a translucent source and destination.
841 Added tests for translucent source and destination.
842 Added tests to check 8-bit/sample and double/sample combines work
844 https://rt.cpan.org/Ticket/Display.html?id=29879
846 - writing a 2 or 4 channel image to a JPEG file will now write that
847 image as if composited against a background, black by default,
848 overridable with the i_background tag/parameter.
849 https://rt.cpan.org/Ticket/Display.html?id=29876
851 - writing a 2 or 4 channel image to a PGM/PPM file will now write
852 that image as if composited against a background, black by default,
853 overridable with the i_background tag/parameter.
854 http://rt.cpan.org/Ticket/Display.html?id=30074
856 - writing a 2 or 4 channel image to a BMP file will now write that
857 image as if composited against a background, black by default,
858 overridable with the i_background tag/parameter.
859 http://rt.cpan.org/Ticket/Display.html?id=30075
863 - Imager::Matrix2d->translate() now only requires one of the x or y
865 http://rt.cpan.org/Ticket/Display.html?id=29937
867 - mixing qtype scaling now sets all channels of a pixel to zero if
868 the pixel has zero coverage (zero alpha). This should produce more
869 compressible output files.
870 http://rt.cpan.org/Ticket/Display.html?id=32324
872 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
874 https://bugzilla.redhat.com/show_bug.cgi?id=166254
875 I'm not changing the #! lines of the sample code, since it's sample
876 code, not intended for installation.
877 http://rt.cpan.org/Ticket/Display.html?id=33408
879 - some TGA images weren't being detected correctly as TGA images
880 https://rt.cpan.org/Ticket/Display.html?id=32925
882 - handling of the left-over bit for 16-bit/pixel TGA images has been
883 changed to match the behaviour of the GIMP. Previously the bit
884 being set was treated as an opaque pixel, but one user reported a
885 problem with loading such an image. I haven't been able to find any
886 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
887 I'll match it's behaviour. See issue 114913 in the GIMP's
889 http://rt.cpan.org/Ticket/Display.html?id=32926
891 Imager 0.62 - 10 December 2007
894 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
895 to /path under your home directory.
896 http://rt.cpan.org/Ticket/Display.html?id=29484
898 - the old dynaload code used Mach API functions to load dynamic
899 libraries on Mac OS X. These APIs have been deprecated in OS X
900 10.5 and were causing some build problems.
901 So henceforth Imager uses the dlopen() family of functions, and you
902 will need version 10.3 or later of OS X.
904 - added the det() function to the transform2() engine.
905 added the sample quad_to_square.pl
906 Courtesy Richard Fairhurst.
907 http://rt.cpan.org/Ticket/Display.html?id=31244
911 - samples/gifscale.pl sourced the base value for gif_top from
913 Thanks to Eleneldil G. Arilou for pointing this out.
915 - t/t82inline.t no longer loads B at runtime, to work around a bug
916 in some 5.005_0[45] installations.
917 http://rt.cpan.org/Ticket/Display.html?id=30508
919 - work around Module::Depends::Intrusive bug #21229
920 http://rt.cpan.org/Ticket/Display.html?id=30520
922 - the hardinvert filter no-longer inverts the alpha channel.
923 http://rt.cpan.org/Ticket/Display.html?id=30002
925 - the hardinvert filter now supports large samples
927 Imager 0.61_02 - 28 November 2007
930 - major TIFF support re-work
931 http://rt.cpan.org/Ticket/Display.html?id=20329
933 - added a C level image interface for accessing samples from 1-32
934 bits, exposed this at the perl level in getsamples()
936 - the conv filter now works at floating point precision for high bit
939 - added is_bilevel method to test whether an image should be written as
940 a bilevel image if the image format supports it.
942 - added -log-stderr as an Imager import list option
944 - added some important types to Imager::APIRef
946 - added test_image_double() to Imager::Test
950 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
953 - the scale() method with qtype mixing now handles images with an
954 alpha channel correctly.
956 - fixed a broken link from the "animated GIF" entry in the concept index.
957 Thanks to Slaven Rezic.
958 http://rt.cpan.org/Ticket/Display.html?id=30889
960 - on some perl's the infix expression parser test would fail due to
961 actions in the grammar returning false. Made sure all actions return
963 Thanks to Richard Fairhurst for spending a lot of time in tracking
965 http://rt.cpan.org/Public/Bug/Display.html?id=29562
967 Imager 0.61 - 5 November 2007
970 - added samples/gifscale.pl, which adjusts the screen size/position tags
971 when scaling an animated gif
972 http://rt.cpan.org/Ticket/Display.html?id=27591
976 - correct handling of sz in matrix_transform() - this should allow
977 perspective type transformations to work now.
978 http://rt.cpan.org/Ticket/Display.html?id=29936
980 - prevent a cast to integer warning on x64 builds in datatypes.c
981 also fixed some other type warnings
982 https://rt.cpan.org/Ticket/Display.html?id=30204
984 - some sub-directory tests depended on files produced by the parent
986 http://rt.cpan.org/Ticket/Display.html?id=30203
988 - Imager::Font::Wrap doesn't correctly set savepos
989 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
990 http://rt.cpan.org/Ticket/Display.html?id=29771
992 - test 171 in t/t01introvert.t was failing on perls configured to
994 http://rt.cpan.org/Ticket/Display.html?id=29413
996 - the code for the transform2() uminus operator was missing a break.
997 Added tests for better code coverage of the ops.
998 http://rt.cpan.org/Ticket/Display.html?id=29296
1000 - the SGI RLE compression code could overflow its compression buffer
1001 http://rt.cpan.org/Ticket/Display.html?id=30334
1003 - the 32-bit output function used by the SGI code only handled values
1004 under 0x10000. This was most noticable when writing large RLE images.
1005 http://rt.cpan.org/Ticket/Display.html?id=30335
1007 - validate chan_count for chans == NULL for each of the i_gsamp()
1009 http://rt.cpan.org/Ticket/Display.html?id=28985
1011 - attempt to work around the test failure at
1012 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
1013 http://rt.cpan.org/Ticket/Display.html?id=29562
1015 - improve the error messages produced when attempting to read or write
1016 an unknown image file format.
1017 http://rt.cpan.org/Ticket/Display.html?id=30103
1019 - improve the transform2() documentation
1020 http://rt.cpan.org/Ticket/Display.html?id=29267
1022 - correctly generate the author key in META.yml
1023 http://rt.cpan.org/Ticket/Display.html?id=30377
1025 - correctly blend a rotated (or matrix_transformed()) image when
1026 performing interpolation in the presence of an alpha channel.
1027 Also corrected the centring of the rotated image on the output
1030 Imager 0.60 - 30 August 2007
1033 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
1034 now has full SGI RGB image format, including RLE and 16-bit/sample
1036 https://rt.cpan.org/Ticket/Display.html?id=8666
1038 - logging functions are now available in the API
1040 - applied Gabriel Vasseur's patch
1041 added documentation, further tests, and support for greyscale images
1042 Obviously problems are my fault :)
1043 https://rt.cpan.org/Ticket/Display.html?id=28142
1045 - the mask for ICO/CUR images is now applied as an alpha channel to
1046 the returned image. For the old behaviour, supply ico_masked => 0
1047 to read() or read_multi(). This should be less confusing when
1048 using Imager as a general image processor.
1049 https://rt.cpan.org/Ticket/Display.html?id=29001
1053 - in some cases it's possible for giflib/libungif to return color
1054 indexes outside the range of colors defined by the image's palette.
1055 We now expand the palette to match the indexes used.
1056 Thanks to Gabriel Vasseur for reporting this.
1058 - fixed various memory leaks that could occur when failing to read png,
1059 jpeg, bmp or tga files.
1061 - to avoid confusion, channels not present in the image are returned as
1062 zero by getscanline(). This has no effect on the C level i_glin()
1063 and i_glinf() API functions which continue to not set the unused
1066 - the convert() method now returns an image of the same sample size as
1068 https://rt.cpan.org/Ticket/Display.html?id=28492
1070 - remove repeated text in Imager::Files
1071 http://rt.cpan.org/Ticket/Display.html?id=27589
1073 - be even more explicit that scale() and friends don't modify the source
1074 image, but return a new image.
1075 http://rt.cpan.org/Ticket/Display.html?id=28570
1077 - improve the error message from errstr() when you try to load a font
1078 for which the driver hasn't been built in Imager.
1079 http://rt.cpan.org/Ticket/Display.html?id=27571
1081 - transparency is now enabled by default when writing GIF images
1082 http://rt.cpan.org/Ticket/Display.html?id=27615
1084 - Imager would not load on Windows 98
1085 http://rt.cpan.org/Ticket/Display.html?id=27653
1087 Imager 0.59 - 14 June 2007
1092 - fixes a regression introduced by the fixes for RT 11972
1093 http://rt.cpan.org/Ticket/Display.html?id=27546
1095 - cropping outside the image would return an Imager object with
1096 no low-level image object, instead of returning false.
1097 Fixed by: Philip Gwyn (Leolo)
1098 http://rt.cpan.org/Ticket/Display.html?id=27509
1100 Imager 0.58 - 16 May 2007
1103 No significant changes from 0.57_01.
1105 Imager 0.57_01 - 11 May 2007
1108 - added to_rgb16 to produce a 16-bit/sample version of an image
1110 - improve freetype 1.x text output efficiency
1114 - search another place for rgb.txt, and check all the places
1115 Imager::Color checks when deciding whether to skip testing it
1116 http://rt.cpan.org/Ticket/Display.html?id=26064
1118 - use a convolution kernel size based on the stddev rather than a
1119 fixed size when performing a gaussian blur
1120 http://rt.cpan.org/Ticket/Display.html?id=25645
1122 - document the difference() method's mindist parameter, and debug it.
1124 - put the Imager release number in the Inline::C generated code to
1125 regenerate Inline code when a new release of Imager is installed.
1126 http://rt.cpan.org/Ticket/Display.html?id=26278
1128 - fix rendering on alpha channel images for the FreeType 1.x driver.
1129 http://rt.cpan.org/Ticket/Display.html?id=11972
1131 - fix rendering on alpha channel images for the T1lib driver.
1132 http://rt.cpan.org/Ticket/Display.html?id=11972
1134 - reworked library probing, we can now set more than one probe
1135 function for a library. Disabled the default (non-freetype-config)
1136 library probe and added an extra probe function that searches for
1137 both ft2build.h and whatever it includes, and adds -I as needed.
1138 Hopefully this will fix build problems like

1140 http://rt.cpan.org/Ticket/Display.html?id=26086
1142 Imager 0.57 - 30 Apr 2007
1145 This is a maintenence release fixing a security issue in Imager.
1147 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
1148 overflow in malloced memory. There will be further discussion of
1149 this issue in the ticket below.
1150 http://rt.cpan.org/Ticket/Display.html?id=26811
1151 CVE-2007-2459 CVE-2007-2413
1152 The descriptions at cve.mitre.org varied in quality, please see the
1153 ticket at rt.cpan.org for a more accurate description of the issue.
1155 Imager 0.56 - 1 Apr 2007
1158 - added support for reading 16-bit/sample PGM/PPM images
1160 - added support for writing 16-bit/sample PGM/PPM images
1162 - improved performance of reading PBM/PGM/PPM images
1164 - added support for writing PBM images if the image is paletted and
1165 contains only black and white
1167 - added a new make_colors value - "mono"
1169 - switched from the svn log Changes to a manual Changes to reduce
1172 - new sample code - samples/flasher.pl
1176 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
1177 was returning an image object with an extra reference, this
1178 resulted in a memory leak.
1179 http://rt.cpan.org/Ticket/Display.html?id=24992
1181 - fix rendering on alpha channel images for the FreeType 2.x driver
1182 http://rt.cpan.org/Ticket/Display.html?id=11972
1184 - reading bmp files now consitently handles short reads. You can now
1185 supply a parameter to treat a short read as successful and set
1187 http://rt.cpan.org/Ticket/Display.html?id=8426
1189 - previously, reading ASCII PBM files required spaces between samples,
1190 even though the format doesn't require that
1192 - improved documentation of the unsharpmask filter (I hope)
1193 http://rt.cpan.org/Ticket/Display.html?id=25531
1195 - force flushing of the output from i_tt_dump_names() and test output
1196 in t/t35ttfont.t to prevent output from being mixed up.
1197 https://rt.cpan.org/Ticket/Display.html?id=24859
1199 - rewrite a conditional expression as an if() to hopefully work around
1200 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
1201 https://rt.cpan.org/Ticket/Display.html?id=25561
1203 - avoid Data::Dumper in regops.perl to support older releases of perl
1204 https://rt.cpan.org/Ticket/Display.html?id=24391
1206 Imager 0.55 - 16 Dec 2006
1209 This is primarily a bug fix release.
1211 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1213 There is one new feature:
1215 - the Win32 font driver now supports UTF8 (RT 22166)
1216 http://www.cpanforum.com/threads/3276
1217 http://rt.cpan.org/Ticket/Display.html?id=22166
1219 Several bugs were fixed:
1221 - the string() method would not output the string "0"
1222 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1224 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1225 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1227 - the gif_disposal and gif_user_input tags weren't being read from
1229 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1231 - gif.c was failing to build under MSVC
1232 http://rt.cpan.org/Ticket/Display.html?id=23922
1234 - in some cases strings passed to the string() method were treated as
1235 terminated by NUL (chr 0)
1236 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1238 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1239 that's the default build name for zlib on Win32.
1240 http://rt.cpan.org/Ticket/Display.html?id=23064
1242 - search $Config{incpath} for headers too, which we should have been
1245 Win32 font driver fixes:
1247 - the global descent value from bounding box was the wrong sign
1248 http://www.cpanforum.com/threads/3276
1250 - if the first or last glyph overflowed the left or right side of the
1251 advance width they would be clipped
1254 Imager 0.54 - 14 Sep 2006
1257 This is primarily a feature release:
1259 - a new qtype value 'mixing' has been added to the scale()
1260 method. This is faster than 'normal', slower than 'preview'. This
1261 is based on the method used by pnmscale, and seems to produce less
1262 blurry results than normal.
1263 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1265 - the rubthrough() method can now render onto images with an alpha
1267 http://rt.cpan.org/Ticket/Display.html?id=20678
1269 - the read_multi() method now falls back to calling doing a single
1270 image read via the read() method and write_multi() will now fall
1271 back to calling write() if a single image is supplied. This means
1272 you can simply call the read_multi() or write_multi() functions
1273 without having to check if the type is formatted by that method.
1274 http://rt.cpan.org/Ticket/Display.html?id=19457
1275 http://rt.cpan.org/Ticket/Display.html?id=19458
1277 - the GIF loop extension can now be written. If you don't have
1278 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1280 http://rt.cpan.org/Ticket/Display.html?id=21185

1339 inverted CMYK that photoshop (and Corel for example) produce into RGB.
