1 Imager release history. Older releases can be found in Changes.old
6 - Imager no longer inherits from Exporter (unless you're running an
11 - re-work, document and test Imager's logging facility.
12 https://rt.cpan.org/Ticket/Display.html?id=65227
14 - fix META.yml testing and the generated META.yml
15 https://rt.cpan.org/Ticket/Display.html?id=65235
17 - test and add error reporting to to_*() family methods
19 Imager 0.83 - 21 May 2011
24 - diag() the error message on failure for some TIFF tests that are
25 failing on a Solaris smoker.
26 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
28 Imager 0.82_01 - 17 May 2011
31 Dev release, in case the compose tests are too sensitive.
35 - Imager::Font::T1 incorrectly checked for absolute filename under
36 Win32. Thanks to kmx for the report and fix.
37 https://rt.cpan.org/Ticket/Display.html?id=67963
39 - compose() with the target, source or mask position off the top or
40 left of the target image didn't clip the source image correctly.
41 https://rt.cpan.org/Ticket/Display.html?id=67220
43 - compose() now returns a useful error message on a non-positive
46 - compose.im now at 100% test coverage. (As opposed to, umm, much,
49 Imager 0.82 - 14 Mar 2011
54 - eliminate calls to i_has_format() from the test suite, since it's
55 no longer a useful way to check for file format support. Eliminate
56 i_has_format() from the functions exposed via XS.
57 https://rt.cpan.org/Ticket/Display.html?id=65863
59 - eliminate calls to note(), which isn't in the (very old) version of
60 Test::More we have as a pre-requisite. note() is modern enough
61 that I don't feel a need to require a Test::More upgrade for it.
62 https://rt.cpan.org/Ticket/Display.html?id=65864
64 - skip the threads tests on Test::More 2.00_*
65 https://rt.cpan.org/Ticket/Display.html?id=65812
67 - add an (unshipped) test to check Imager's internal POD links
68 https://rt.cpan.org/Ticket/Display.html?id=65749
70 - improve the library detection summary
71 https://rt.cpan.org/Ticket/Display.html?id=9675
73 - increase the version of Imager::Font::Type1 so that upgrades don't
74 downgrade the version in this file.
75 https://rt.cpan.org/Ticket/Display.html?id=66250
77 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
78 that option for the directories that would normally go in
79 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
80 https://rt.cpan.org/Ticket/Display.html?id=65955
82 Imager 0.81 - 14 Feb 2011
85 - added coverage tests for masked images (maskimg.c @100% test coverage)
87 - add hsv() method to Imager::Color
88 Thanks to Leolo (Philip Gwyn)
89 https://rt.cpan.org/Ticket/Display.html?id=65385
91 - split libt1 Type 1 font support into a sub-module
92 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
94 - add a preload() class method for use in forking servers, and to
95 work around limitations in PAR.
96 https://rt.cpan.org/Ticket/Display.html?id=65665
100 - paletted writes to a masked image are now masked correctly.
101 Revealed by new coverage tests.
103 - update the filter plugin documentation.
104 https://rt.cpan.org/Ticket/Display.html?id=56513
106 - add the matrix() method to Imager::Matrix2d to allow creation of a
107 matrix with specified co-efficients. You can now multiple an
108 Imager::Matrix2d object by a 9 element array ref or a number.
109 https://rt.cpan.org/Ticket/Display.html?id=29938
111 - really fix loading TTF fonts with FT2 when FT1 isn't available.
112 Thanks to Leolo (Philip Gwyn)
113 https://rt.cpan.org/Ticket/Display.html?id=65386
114 https://rt.cpan.org/Ticket/Display.html?id=62855
116 - make sure each test script that needs testout/ creates it.
117 https://rt.cpan.org/Ticket/Display.html?id=65088
119 - handle a slightly different warning from libtiff 4.x
120 https://rt.cpan.org/Ticket/Display.html?id=65268
122 - the sat transform2() op returned an incorrect saturation.
123 https://rt.cpan.org/Ticket/Display.html?id=65391
125 Imager 0.80 - 17 Jan 2011
128 - added coverage tests for Imager::Fountain and Imager::Color::Float
130 - Imager is now maintained in git
131 http://git.imager.perl.org/imager.git
132 git://git.imager.perl.org/imager.git
136 - images with an translucent alpha channel were not scaled correctly
137 by the default (qtype=normal) scaling method.
138 https://rt.cpan.org/Public/Bug/Display.html?id=63922
140 - Imager::Color::Float now translates "#FFFFFF" to white instead of
141 just a little darker.
143 - make the default color map build algorithm "mediancut". This
144 changes the default color map builder for writing GIFs back to what
145 it was in 0.77, reverting a performance regression.
146 https://rt.cpan.org/Ticket/Display.html?id=64785
148 - handle failure to create a masked image correctly
150 Imager 0.79 - 10 Dec 2010
153 - add Imager::Test to the POD coverage tests and document the missing
156 - the convert() method now optimizes the case where all output
157 channels are either 0, sourced from a single input channel or 1.
158 This significantly speeds up presets like "addalpha", "green".
159 https://rt.cpan.org/Ticket/Display.html?id=51254
161 - add wiggle.pl sample, as suggested by Dan Oppenheim.
163 - add the combine() method to combine channels from multiple source
164 images into a new image
165 https://rt.cpan.org/Ticket/Display.html?id=11872
169 - treat the co-efficients for convert() as doubles instead of floats.
171 - If a higher (earlier) priority font handler failed to load, that
172 would crash preventing loading of later font handlers.
173 https://rt.cpan.org/Ticket/Display.html?id=62855
175 - parse defines from the options returned by pkg-config --cflags
176 https://rt.cpan.org/Ticket/Display.html?id=63223
178 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
179 included in the tarball. They are now included.
181 Imager 0.78 - 4 Oct 2010
186 - don't access deprecated members of the png_structp.
187 https://rt.cpan.org/Ticket/Display.html?id=60242
189 - document that using color objects is faster than supplying colors
191 https://rt.cpan.org/Ticket/Display.html?id=61047
193 - Imager::Probe now accepts array references for incpath and libpath.
194 https://rt.cpan.org/Ticket/Display.html?id=60244
196 Imager 0.77_02 - 27 Sep 2010
199 - moved Win32, FreeType 2 font support into sub-modules.
200 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
201 Uses Imager::Probe now.
202 https://rt.cpan.org/Public/Bug/Display.html?id=61328
204 - tested successfully with jpeg-8b
205 https://rt.cpan.org/Ticket/Display.html?id=60221
209 - from _01: look for missing file support test files in the right
212 - flood_fill() wouldn't fill the right side of a single scan-line
214 Thanks to Nicolas Roggli for reporting this.
216 - flood_fill wouldn't fill to the left edge of the image if the
217 starting line didn't reach the left edge.
218 Thanks to Nicolas Roggli for reporting this.
220 Imager 0.77_01 - 13 Sep 2010
223 - add each library-directory/pkgconfig/ to the pkg-config search path
225 Thanks to Justin Davis.
226 https://rt.cpan.org/Ticket/Display.html?id=60491
228 - moved GIF, TIFF, JPEG file handling code into sub-modules in
229 preparation for separate distribution.
230 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
232 - optimize filled box drawing (color, not fill)
236 - Imager::Probe was calling ExtUtils::Liblist to initialize
237 LD_RUN_PATH supplying an undefined value rather than the found
238 directory. Thanks to Justin Davis.
239 https://rt.cpan.org/Ticket/Display.html?id=60491
241 - only prepend ./ to font filenames when passing them to T1Lib and
242 then only when it would use its search mechanisms.
243 https://rt.cpan.org/Ticket/Display.html?id=60509
245 - fix the cache check for the X rgb.txt loader. This is typically
246 used for color translation on Unix-like systems, and the fix
247 improves performance of supplying colors by name by about 80 times.
248 Test code that managed 3400 10x10 pixel boxes/second sped up to
251 - clarify that Imager doesn't write EXIF metadata to images.
252 https://rt.cpan.org/Ticket/Display.html?id=60637
254 - Imager::Probe can now search subdirectories under its include path.
255 Used by the PNG Makefile.PL to find headers and libraries when they
256 aren't in the base directory, as in cygwin.
257 https://rt.cpan.org/Ticket/Display.html?id=60635
259 Imager 0.77 - 11 Aug 2010
262 I don't want Imager::File::PNG indexed as part of Imager, but forgot
263 to update the META.yml before updating the version.
265 - don't index Imager::File::PNG as part of Imager
267 - add resources to META.yml
269 Imager 0.76 - not released
274 - the align_string() method would ignore a string of "0" due to a
276 Thanks to Maurice Height for reporting this.
277 https://rt.cpan.org/Ticket/Display.html?id=60199
279 Imager 0.75_03 - 09 Aug 2010
284 - read_types() and write_types() would include png when it wasn't
285 available due to a problem with the %formats tie
287 - handle dependent libraries correctly (eg -lpng requiring -lz) in
288 the code run phase of library probing.
290 Imager 0.75_02 - 07 Aug 2010
295 - add file missing from MANIFEST, which was causing TIFF failures.
297 Imager 0.75_01 - 06 Aug 2010
300 Test release for the new PNG probe.
302 - added the ability to read multiple-image PNM files.
303 Note that unlike the pbm/pgm/ppm specification this accepts mixed
304 format files and allows white space padding between files.
305 Thanks to Philip Gwyn (Leolo) for this patch.
307 - moved the PNG file handling code into a sub-module in preparation
308 for separate distribution.
309 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
310 Also helps avoid complications from -I/-L compile/link options from
315 - Imager->new(data => $data) didn't try to process image file data in
317 https://rt.cpan.org/Ticket/Display.html?id=58761
319 - t/t50basicoo.t no longer depends on the other tests to generate its
321 https://rt.cpan.org/Ticket/Display.html?id=9798
322 Also, it wasn't testing pnm (pnm vs ppm mix-up)
324 - update the documentation of hardinvert to match the change in 0.62.
325 https://rt.cpan.org/Ticket/Display.html?id=59785
327 - added hardinvertall filter which also inverts the alpha channel
330 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
331 the probe can find the library for the test run.
332 https://rt.cpan.org/Ticket/Display.html?id=57518
334 Imager 0.75 - 20 Jun 2010
337 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
342 - an opacity fill based on a fountain fill would segfault when
343 filling an 8-bit/sample image.
345 - merge thickline branch polygon fix
346 https://rt.cpan.org/Ticket/Display.html?id=43518
348 Imager 0.74 - 7 May 2010
353 - read_multi() didn't handle a missing file format library correctly,
354 aborting on failing to call i_readgif_multi_wiol() or
355 i_readtiff_multi_wiol().
357 - fix spelling errors patched by Debian
358 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
360 - add an (unshipped) author test to spellcheck Imager's POD.
362 - update the TIFF file format documentation
363 https://rt.cpan.org/Ticket/Display.html?id=56510
365 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
367 Imager 0.73 - 15 Mar 2010
370 - implement outline circles, both anti-aliased and not
371 https://rt.cpan.org/Ticket/Display.html?id=19755
373 - a combine => "none" fill to a 1 or 3 channel image would produce
374 the incorrect colour.
376 Imager 0.72 - 09 Dec 2009
379 Bump version for release, since 0.71_03 is stable with CPAN testers.
381 Imager 0.71_03 - 5 Dec 2009
384 - further adjust the threads test so it only performs the tests on
385 perls where it's expected to work, and only if the threads module
388 Imager 0.71_02 - 1 Dec 2009
391 - adjust the way we load the threads module for the threads test so
392 it works with non-threaded perls
394 Imager 0.71_01 - 30 Nov 2009
399 - use scanline oriented operations to flip images instead of pixel
401 https://rt.cpan.org/Ticket/Display.html?id=39278
403 - use double/sample operations to flip large sample images instead of
404 8-bit sample operations.
405 https://rt.cpan.org/Ticket/Display.html?id=39280
408 https://rt.cpan.org/Ticket/Display.html?id=51874
410 - prevent double-frees when someone creates Imager objects and then
411 creates a thread. Note: this just handles some simple cases,
412 Imager doesn't support perl threads, and isn't likely to.
413 https://rt.cpan.org/Ticket/Display.html?id=52268
415 Imager 0.71 - 16 Nov 2009
418 - add the opacity fill type - an adaptor that modifies the opacity of
423 - the conv filter now enforces that the sum of the coefficients is
424 non-zero. Also, rather than skipping pixels off the edge off the
425 edge of the image, the closest edge pixel is used. Previously
426 dividing by the zero sum of coefficients could cause invalid
427 results or runtime exceptions.
428 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
431 Imager 0.70 - 21 Sep 2009
436 - release image row and comments memory on all error returns in gif
439 - handle zero length extensions, previously this would cause a null
441 Thanks to Krzysztof Wojtaś for the test data and fix for this.
443 - an integer division meant that preview scaling to below 1 pixel
444 wide or high (which isn't too useful anyway) was calculating using
445 NaNs on most platforms, and causing an exception on others.
446 Thanks to David Cantrell for producing a backtrace of the crash on
447 his Alpha-NetBSD CPAN test box which made it possible to track this
450 Imager 0.69 - 08 Sep 2009
455 - broken test fix - was attempting to call a function skip_all, when
456 that should be a parameter to plan().
458 - briefly document apidocs.perl, the tool used to build
459 Imager::APIRef and make some minor enhancements
461 - various minor documentation enhancements and fixes.
463 Imager 0.68 - 07 Sep 2009
466 - Imager->new(file => $filename) and other similar incantations will
468 https://rt.cpan.org/Ticket/Display.html?id=48261
472 - avoid using CHECK as a label in Imager::Test
473 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
475 - re-work most image file test files that require a library into
476 separate library present/not present files to remove stupidly long
479 - don't treat rubthrough() outside the bounds of the target image as
481 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
483 Imager 0.67_01 - 02 Sep 2009
488 - correct documentation of default of raw image interleave read
490 https://rt.cpan.org/Ticket/Display.html?id=42074
492 - add raw_ prefix to raw read parameters, though the original names
495 - fail the read if an invalid raw_interleave parameter is supplied
497 - warn if no interleave or raw_interleave parameter is supplied,
498 since the documented default was wrong, and incompatible with the
501 - for reading raw images, if raw_storechannels > raw_datachannels,
502 set the extra channels in the image to 0
504 - when probing for executables like freetype-config, search for .bat
505 and .cmd on MSWin32, as well as .exe.
506 https://rt.cpan.org/Ticket/Display.html?id=49275
508 - re-work the external libraries section of README:
509 - list Debian and Redhat package names for each library
513 - use the new EU::MM META_MERGE facility instead of generating
514 META.yml from scratch
515 https://rt.cpan.org/Ticket/Display.html?id=47888
517 - use Devel::CheckLib (bundled, modified) to check which release of
518 libtiff is installed and reject 3.9.0
519 http://bugzilla.maptools.org/show_bug.cgi?id=2088
520 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
522 Imager 0.67 - 12 Dec 2008
527 - fix a packaging error
529 Imager 0.66 - 12 Dec 2008
532 - 24-bit color .ICO/.CUR files can now be read.
536 - an optimization skipping 0 src alpha values could cause the
537 rubthrough() to read past the end of a buffer.
538 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
540 - corrected a reference leak where writing GIFs would leak memory.
541 This could also happen calling to_paletted().
542 Also documented the underlying long existing feature where the
543 colors parameter is filled with the generated color table and added
545 http://rt.cpan.org/Ticket/Display.html?id=41028
547 - write out the image size in bytes field of a BMP correctly.
548 http://rt.cpan.org/Ticket/Display.html?id=41406
550 - add limited tests for Imager::ExtUtils
552 - make Imager::ExtUtils->includes use an absolute path, since
553 a relative path could cause failures using Inline::C.
554 http://rt.cpan.org/Ticket/Display.html?id=37353
556 - re-arrange the POD for Imager::Font::BBox:
557 - mark total_width(), pos_width(), end_offset() obsolete, since
558 they're mostly for backwards compatibility
559 - group width methods and height methods
560 https://rt.cpan.org/Ticket/Display.html?id=39999
562 Imager 0.65 - 20 May 2008
567 - In some cases when an error occurs reading those parts of a JPEG
568 file after the image the scan-line buffer could be freed a second
569 time. In cases where the the error occured while reading the image
570 data it's possible that the buffer could have leaked.
571 Thanks to Gabriel Vasseur for reporting this and help in tracking
574 - the gif_screen_height tag was overriding the screen width and being
575 ignored for the screen height when present.
576 https://rt.cpan.org/Public/Bug/Display.html?id=35568
578 Imager 0.64 - 23 April 2008
581 This is a bug fix release. This includes a fix for a possible
586 - Possible security issue: The floating point sample path for image
587 based fills had a buffer overflow. This would overwrite the end of
588 a malloc()ed buffer with double precision floats.
589 http://rt.cpan.org/Ticket/Display.html?id=35324
592 - check that the result of fileno($fh) is defined rather than simply
593 true when read() or write() is supplied with an fh parameter.
594 http://rt.cpan.org/Ticket/Display.html?id=35139
596 - i_scale_axis() wasn't checking the result of i_img_new_ch()
597 resulting in a SIGSEGV when attempting to scale an image to a size
598 too large to fit in memory. This is a NULL pointer access issue,
599 not a buffer overflow.
600 Added a check for the failure.
601 scale_calculate() (and hence scale()) will now fail if any of the
602 scale size parameters are a reference.
603 http://rt.cpan.org/Ticket/Display.html?id=35172
605 - Regression: filling a greyscale image with a hatch used the wrong
606 color channels from the supplied fg/bg colors.
607 https://rt.cpan.org/Ticket/Display.html?id=35278
609 - fixed a related problem for image fills.
611 Imager 0.63 - 7 April 2008
614 This release primarily contains changes to improve ease of use -
615 rather than you having to convert images to the appropriate number of
616 channels, Imager handles it internally. How to handle drawing colors
617 and the default combine mode is a thornier problem left for some other
620 - the font libraries are now only initialized when needed.
621 http://rt.cpan.org/Ticket/Display.html?id=28825
623 - moved the imtoc.perl code into Imager::Preprocess
625 - paste() and rubthrough() now adapt the source image data to the
626 destination, so you can now safely paste/rubthrough from greyscale
627 images to color images or back, or from alpha channel images to
628 noalpha channels or back.
629 https://rt.cpan.org/Ticket/Display.html?id=30908
631 - rubthrough() now falls back to pasting when the source doesn't have
632 an alpha channel. This effectively treats the source as having a
633 max alpha channel, the right thing to do.
634 http://rt.cpan.org/Ticket/Display.html?id=29944
636 - re-worked most of the area filling code to use a common set of
637 functions when filling.
638 Corrected normal combine mode.
639 Rewrote most of the combine modes to match the way the SVG draft
640 defines them with respect to a translucent source and destination.
641 Added tests for translucent source and destination.
642 Added tests to check 8-bit/sample and double/sample combines work
644 https://rt.cpan.org/Ticket/Display.html?id=29879
646 - writing a 2 or 4 channel image to a JPEG file will now write that
647 image as if composited against a background, black by default,
648 overridable with the i_background tag/parameter.
649 https://rt.cpan.org/Ticket/Display.html?id=29876
651 - writing a 2 or 4 channel image to a PGM/PPM file will now write
652 that image as if composited against a background, black by default,
653 overridable with the i_background tag/parameter.
654 http://rt.cpan.org/Ticket/Display.html?id=30074
656 - writing a 2 or 4 channel image to a BMP file will now write that
657 image as if composited against a background, black by default,
658 overridable with the i_background tag/parameter.
659 http://rt.cpan.org/Ticket/Display.html?id=30075
663 - Imager::Matrix2d->translate() now only requires one of the x or y
665 http://rt.cpan.org/Ticket/Display.html?id=29937
667 - mixing qtype scaling now sets all channels of a pixel to zero if
668 the pixel has zero coverage (zero alpha). This should produce more
669 compressible output files.
670 http://rt.cpan.org/Ticket/Display.html?id=32324
672 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
674 https://bugzilla.redhat.com/show_bug.cgi?id=166254
675 I'm not changing the #! lines of the sample code, since it's sample
676 code, not intended for installation.

679 - some TGA images weren't being detected correctly as TGA images
680 https://rt.cpan.org/Ticket/Display.html?id=32925
682 - handling of the left-over bit for 16-bit/pixel TGA images has been
683 changed to match the behaviour of the GIMP. Previously the bit
684 being set was treated as an opaque pixel, but one user reported a
685 problem with loading such an image. I haven't been able to find any
686 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
687 I'll match it's behaviour. See issue 114913 in the GIMP's
689 http://rt.cpan.org/Ticket/Display.html?id=32926
691 Imager 0.62 - 10 December 2007
694 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
695 to /path under your home directory.
696 http://rt.cpan.org/Ticket/Display.html?id=29484
698 - the old dynaload code used Mach API functions to load dynamic
699 libraries on Mac OS X. These APIs have been deprecated in OS X
700 10.5 and were causing some build problems.
701 So henceforth Imager uses the dlopen() family of functions, and you
702 will need version 10.3 or later of OS X.
704 - added the det() function to the transform2() engine.
705 added the sample quad_to_square.pl
706 Courtesy Richard Fairhurst.
707 http://rt.cpan.org/Ticket/Display.html?id=31244
711 - samples/gifscale.pl sourced the base value for gif_top from
713 Thanks to Eleneldil G. Arilou for pointing this out.
715 - t/t82inline.t no longer loads B at runtime, to work around a bug
716 in some 5.005_0[45] installations.
717 http://rt.cpan.org/Ticket/Display.html?id=30508
719 - work around Module::Depends::Intrusive bug #21229
720 http://rt.cpan.org/Ticket/Display.html?id=30520
722 - the hardinvert filter no-longer inverts the alpha channel.
723 http://rt.cpan.org/Ticket/Display.html?id=30002
725 - the hardinvert filter now supports large samples
727 Imager 0.61_02 - 28 November 2007
730 - major TIFF support re-work
731 http://rt.cpan.org/Ticket/Display.html?id=20329
733 - added a C level image interface for accessing samples from 1-32
734 bits, exposed this at the perl level in getsamples()
736 - the conv filter now works at floating point precision for high bit
739 - added is_bilevel method to test whether an image should be written as
740 a bilevel image if the image format supports it.
742 - added -log-stderr as an Imager import list option
744 - added some important types to Imager::APIRef
746 - added test_image_double() to Imager::Test
750 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
753 - the scale() method with qtype mixing now handles images with an
754 alpha channel correctly.
756 - fixed a broken link from the "animated GIF" entry in the concept index.
757 Thanks to Slaven Rezic.
758 http://rt.cpan.org/Ticket/Display.html?id=30889
760 - on some perl's the infix expression parser test would fail due to
761 actions in the grammar returning false. Made sure all actions return
763 Thanks to Richard Fairhurst for spending a lot of time in tracking
765 http://rt.cpan.org/Public/Bug/Display.html?id=29562
767 Imager 0.61 - 5 November 2007
770 - added samples/gifscale.pl, which adjusts the screen size/position tags
771 when scaling an animated gif
772 http://rt.cpan.org/Ticket/Display.html?id=27591
776 - correct handling of sz in matrix_transform() - this should allow
777 perspective type transformations to work now.
778 http://rt.cpan.org/Ticket/Display.html?id=29936
780 - prevent a cast to integer warning on x64 builds in datatypes.c
781 also fixed some other type warnings
782 https://rt.cpan.org/Ticket/Display.html?id=30204
784 - some sub-directory tests depended on files produced by the parent
786 http://rt.cpan.org/Ticket/Display.html?id=30203
788 - Imager::Font::Wrap doesn't correctly set savepos
789 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
790 http://rt.cpan.org/Ticket/Display.html?id=29771
792 - test 171 in t/t01introvert.t was failing on perls configured to
794 http://rt.cpan.org/Ticket/Display.html?id=29413
796 - the code for the transform2() uminus operator was missing a break.
797 Added tests for better code coverage of the ops.
798 http://rt.cpan.org/Ticket/Display.html?id=29296
800 - the SGI RLE compression code could overflow its compression buffer
801 http://rt.cpan.org/Ticket/Display.html?id=30334
803 - the 32-bit output function used by the SGI code only handled values
804 under 0x10000. This was most noticable when writing large RLE images.
805 http://rt.cpan.org/Ticket/Display.html?id=30335
807 - validate chan_count for chans == NULL for each of the i_gsamp()
809 http://rt.cpan.org/Ticket/Display.html?id=28985
811 - attempt to work around the test failure at
812 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
813 http://rt.cpan.org/Ticket/Display.html?id=29562
815 - improve the error messages produced when attempting to read or write
816 an unknown image file format.
817 http://rt.cpan.org/Ticket/Display.html?id=30103
819 - improve the transform2() documentation
820 http://rt.cpan.org/Ticket/Display.html?id=29267
822 - correctly generate the author key in META.yml
823 http://rt.cpan.org/Ticket/Display.html?id=30377
825 - correctly blend a rotated (or matrix_transformed()) image when
826 performing interpolation in the presence of an alpha channel.
827 Also corrected the centring of the rotated image on the output
830 Imager 0.60 - 30 August 2007
833 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
834 now has full SGI RGB image format, including RLE and 16-bit/sample
836 https://rt.cpan.org/Ticket/Display.html?id=8666
838 - logging functions are now available in the API
840 - applied Gabriel Vasseur's patch
841 added documentation, further tests, and support for greyscale images
842 Obviously problems are my fault :)
843 https://rt.cpan.org/Ticket/Display.html?id=28142
845 - the mask for ICO/CUR images is now applied as an alpha channel to
846 the returned image. For the old behaviour, supply ico_masked => 0
847 to read() or read_multi(). This should be less confusing when
848 using Imager as a general image processor.
849 https://rt.cpan.org/Ticket/Display.html?id=29001
853 - in some cases it's possible for giflib/libungif to return color
854 indexes outside the range of colors defined by the image's palette.
855 We now expand the palette to match the indexes used.
856 Thanks to Gabriel Vasseur for reporting this.
858 - fixed various memory leaks that could occur when failing to read png,
859 jpeg, bmp or tga files.
861 - to avoid confusion, channels not present in the image are returned as
862 zero by getscanline(). This has no effect on the C level i_glin()
863 and i_glinf() API functions which continue to not set the unused
866 - the convert() method now returns an image of the same sample size as
868 https://rt.cpan.org/Ticket/Display.html?id=28492
870 - remove repeated text in Imager::Files
871 http://rt.cpan.org/Ticket/Display.html?id=27589
873 - be even more explicit that scale() and friends don't modify the source
874 image, but return a new image.
875 http://rt.cpan.org/Ticket/Display.html?id=28570
877 - improve the error message from errstr() when you try to load a font
878 for which the driver hasn't been built in Imager.
879 http://rt.cpan.org/Ticket/Display.html?id=27571
881 - transparency is now enabled by default when writing GIF images
882 http://rt.cpan.org/Ticket/Display.html?id=27615
884 - Imager would not load on Windows 98
885 http://rt.cpan.org/Ticket/Display.html?id=27653
887 Imager 0.59 - 14 June 2007
892 - fixes a regression introduced by the fixes for RT 11972
893 http://rt.cpan.org/Ticket/Display.html?id=27546
895 - cropping outside the image would return an Imager object with
896 no low-level image object, instead of returning false.
897 Fixed by: Philip Gwyn (Leolo)
898 http://rt.cpan.org/Ticket/Display.html?id=27509
900 Imager 0.58 - 16 May 2007
903 No significant changes from 0.57_01.
905 Imager 0.57_01 - 11 May 2007
908 - added to_rgb16 to produce a 16-bit/sample version of an image
910 - improve freetype 1.x text output efficiency
914 - search another place for rgb.txt, and check all the places
915 Imager::Color checks when deciding whether to skip testing it
916 http://rt.cpan.org/Ticket/Display.html?id=26064
918 - use a convolution kernel size based on the stddev rather than a
919 fixed size when performing a gaussian blur
920 http://rt.cpan.org/Ticket/Display.html?id=25645
922 - document the difference() method's mindist parameter, and debug it.
924 - put the Imager release number in the Inline::C generated code to
925 regenerate Inline code when a new release of Imager is installed.
926 http://rt.cpan.org/Ticket/Display.html?id=26278
928 - fix rendering on alpha channel images for the FreeType 1.x driver.
929 http://rt.cpan.org/Ticket/Display.html?id=11972
931 - fix rendering on alpha channel images for the T1lib driver.
932 http://rt.cpan.org/Ticket/Display.html?id=11972
934 - reworked library probing, we can now set more than one probe
935 function for a library. Disabled the default (non-freetype-config)
936 library probe and added an extra probe function that searches for
937 both ft2build.h and whatever it includes, and adds -I as needed.
938 Hopefully this will fix build problems like
939 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
940 http://rt.cpan.org/Ticket/Display.html?id=26086
942 Imager 0.57 - 30 Apr 2007
945 This is a maintenence release fixing a security issue in Imager.
947 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
948 overflow in malloced memory. There will be further discussion of
949 this issue in the ticket below.
950 http://rt.cpan.org/Ticket/Display.html?id=26811
951 CVE-2007-2459 CVE-2007-2413
952 The descriptions at cve.mitre.org varied in quality, please see the
953 ticket at rt.cpan.org for a more accurate description of the issue.
955 Imager 0.56 - 1 Apr 2007
958 - added support for reading 16-bit/sample PGM/PPM images
960 - added support for writing 16-bit/sample PGM/PPM images
962 - improved performance of reading PBM/PGM/PPM images
964 - added support for writing PBM images if the image is paletted and
965 contains only black and white
967 - added a new make_colors value - "mono"
969 - switched from the svn log Changes to a manual Changes to reduce
972 - new sample code - samples/flasher.pl
976 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
977 was returning an image object with an extra reference, this
978 resulted in a memory leak.
979 http://rt.cpan.org/Ticket/Display.html?id=24992
981 - fix rendering on alpha channel images for the FreeType 2.x driver
982 http://rt.cpan.org/Ticket/Display.html?id=11972
984 - reading bmp files now consitently handles short reads. You can now
985 supply a parameter to treat a short read as successful and set
987 http://rt.cpan.org/Ticket/Display.html?id=8426
989 - previously, reading ASCII PBM files required spaces between samples,
990 even though the format doesn't require that
992 - improved documentation of the unsharpmask filter (I hope)
993 http://rt.cpan.org/Ticket/Display.html?id=25531
995 - force flushing of the output from i_tt_dump_names() and test output
996 in t/t35ttfont.t to prevent output from being mixed up.
997 https://rt.cpan.org/Ticket/Display.html?id=24859
999 - rewrite a conditional expression as an if() to hopefully work around
1000 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
1001 https://rt.cpan.org/Ticket/Display.html?id=25561
1003 - avoid Data::Dumper in regops.perl to support older releases of perl
1004 https://rt.cpan.org/Ticket/Display.html?id=24391
1006 Imager 0.55 - 16 Dec 2006
1009 This is primarily a bug fix release.
1011 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1013 There is one new feature:
1015 - the Win32 font driver now supports UTF8 (RT 22166)
1016 http://www.cpanforum.com/threads/3276
1017 http://rt.cpan.org/Ticket/Display.html?id=22166
1019 Several bugs were fixed:
1021 - the string() method would not output the string "0"
1022 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1024 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1025 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1027 - the gif_disposal and gif_user_input tags weren't being read from
1029 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1031 - gif.c was failing to build under MSVC
1032 http://rt.cpan.org/Ticket/Display.html?id=23922
1034 - in some cases strings passed to the string() method were treated as
1035 terminated by NUL (chr 0)
1036 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1038 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1039 that's the default build name for zlib on Win32.
1040 http://rt.cpan.org/Ticket/Display.html?id=23064
1042 - search $Config{incpath} for headers too, which we should have been
1045 Win32 font driver fixes:
1047 - the global descent value from bounding box was the wrong sign
1048 http://www.cpanforum.com/threads/3276
1050 - if the first or last glyph overflowed the left or right side of the
1051 advance width they would be clipped
1054 Imager 0.54 - 14 Sep 2006
1057 This is primarily a feature release:
1059 - a new qtype value 'mixing' has been added to the scale()
1060 method. This is faster than 'normal', slower than 'preview'. This
1061 is based on the method used by pnmscale, and seems to produce less
1062 blurry results than normal.
1063 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1065 - the rubthrough() method can now render onto images with an alpha
1067 http://rt.cpan.org/Ticket/Display.html?id=20678
1069 - the read_multi() method now falls back to calling doing a single
1070 image read via the read() method and write_multi() will now fall
1071 back to calling write() if a single image is supplied. This means
1072 you can simply call the read_multi() or write_multi() functions
1073 without having to check if the type is formatted by that method.
1074 http://rt.cpan.org/Ticket/Display.html?id=19457
1075 http://rt.cpan.org/Ticket/Display.html?id=19458
1077 - the GIF loop extension can now be written. If you don't have
1078 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1080 http://rt.cpan.org/Ticket/Display.html?id=21185
1082 - getscanline() and setscanline() can now read/write palette index
1083 based data from/to the image for paletted images, by setting type to
1085 http://rt.cpan.org/Ticket/Display.html?id=20338
1087 - we no longer hassle you to disable GIF support
1088 http://rt.cpan.org/Ticket/Display.html?id=20687
1090 - minor documentation fixes
1093 Imager 0.53 - 26 Jul 2006
1096 This is a bugfix release.
1098 Some test code was left in a code path not covered by the test
1099 suite. A test was added to cover this code path and the test code was
1101 http://rt.cpan.org/Public/Bug/Display.html?id=20705
1104 Imager 0.52 - 25 Jul 2006
1107 This is primarily a feature release, but contains a fair few bug
1108 fixes, new features:
1110 - ability to read and write MS Windows ICO and CUR files
1112 - you can now add file format plugins to support new file formats
1114 - add POD coverage tests
1116 - setcolors() and addcolors() now accept color names and so on
1117 instead of requiring Imager::Color objects.
1118 http://rt.cpan.org/Ticket/Display.html?id=20056
1120 - flood_fill() can now fill to a specified border color instead of
1121 just to the area the same color as the seed.
1122 http://rt.cpan.org/Ticket/Display.html?id=19618
1127 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1128 calculating the advance width.
1129 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1131 - bounding_box for the T1 driver wasn't including leading and
1132 trailing spaces in the bounding box as the other drivers did, it also
1133 produced strange results for empty strings or strings containing only
1136 - when reading CMYK jpeg images they were being transferred to the
1137 image object as is, producing a four channel image. It only looked ok
1138 due to an old still unfixed Photoshop bug. We now convert from the
1139 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1140 http://rt.cpan.org/Ticket/Display.html?id=20416
1142 - reading a CYMK TIFF would result in a 4 channel image, reading any
1143 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1145 http://rt.cpan.org/Ticket/Display.html?id=20415
1147 - added /usr/local/include to the default include search path, since
1148 we were already searching /usr/local/lib for libraries.
1150 And various minor fixes and documentation updates.
1153 Imager 0.51 - 23 Apr 2006
1156 - fix a validation bug when processing JPEG EXIF data that can cause
1158 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1160 - fix mis-processing of the src_maxx and src_maxy parameters of the
1162 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1164 - fix a problem in Imager's "smart" handling of the color parameter
1166 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1169 Imager 0.50 - 29 Mar 2006
1172 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1173 or 4 channel image to jpeg or a 2 channel image to tga where the
1174 output is an in-memeory buffer.
1175 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1177 - fixes an incorrect pointer parameter in the PNG code
1178 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1180 - skip Inline::C tests when building in a directory with spaces
1181 http://rt.cpan.org/Public/Bug/Display.html?id=18049
