1 Imager release history. Older releases can be found in Changes.old
3 Imager 0.82 - unreleased
8 - eliminate calls to i_has_format() from the test suite, since it's
9 no longer a useful way to check for file format support. Eliminate
10 i_has_format() from the functions exposed via XS.
11 https://rt.cpan.org/Ticket/Display.html?id=65863
13 Imager 0.81 - 14 Feb 2011
16 - added coverage tests for masked images (maskimg.c @100% test coverage)
18 - add hsv() method to Imager::Color
19 Thanks to Leolo (Philip Gwyn)
20 https://rt.cpan.org/Ticket/Display.html?id=65385
22 - split libt1 Type 1 font support into a sub-module
23 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)

26 work around limitations in PAR.
27 https://rt.cpan.org/Ticket/Display.html?id=65665
31 - paletted writes to a masked image are now masked correctly.
32 Revealed by new coverage tests.

35 https://rt.cpan.org/Ticket/Display.html?id=56513
37 - add the matrix() method to Imager::Matrix2d to allow creation of a
38 matrix with specified co-efficients. You can now multiple an
39 Imager::Matrix2d object by a 9 element array ref or a number.
40 https://rt.cpan.org/Ticket/Display.html?id=29938
42 - really fix loading TTF fonts with FT2 when FT1 isn't available.
43 Thanks to Leolo (Philip Gwyn)
44 https://rt.cpan.org/Ticket/Display.html?id=65386
45 https://rt.cpan.org/Ticket/Display.html?id=62855
47 - make sure each test script that needs testout/ creates it.
48 https://rt.cpan.org/Ticket/Display.html?id=65088
50 - handle a slightly different warning from libtiff 4.x
51 https://rt.cpan.org/Ticket/Display.html?id=65268
53 - the sat transform2() op returned an incorrect saturation.
54 https://rt.cpan.org/Ticket/Display.html?id=65391
56 Imager 0.80 - 17 Jan 2011
59 - added coverage tests for Imager::Fountain and Imager::Color::Float
61 - Imager is now maintained in git
62 http://git.imager.perl.org/imager.git
63 git://git.imager.perl.org/imager.git
67 - images with an translucent alpha channel were not scaled correctly
68 by the default (qtype=normal) scaling method.
69 https://rt.cpan.org/Public/Bug/Display.html?id=63922
71 - Imager::Color::Float now translates "#FFFFFF" to white instead of
74 - make the default color map build algorithm "mediancut". This
75 changes the default color map builder for writing GIFs back to what
76 it was in 0.77, reverting a performance regression.
77 https://rt.cpan.org/Ticket/Display.html?id=64785
79 - handle failure to create a masked image correctly
81 Imager 0.79 - 10 Dec 2010
84 - add Imager::Test to the POD coverage tests and document the missing
87 - the convert() method now optimizes the case where all output
88 channels are either 0, sourced from a single input channel or 1.
89 This significantly speeds up presets like "addalpha", "green".
90 https://rt.cpan.org/Ticket/Display.html?id=51254
92 - add wiggle.pl sample, as suggested by Dan Oppenheim.
94 - add the combine() method to combine channels from multiple source
95 images into a new image
96 https://rt.cpan.org/Ticket/Display.html?id=11872
100 - treat the co-efficients for convert() as doubles instead of floats.
102 - If a higher (earlier) priority font handler failed to load, that
103 would crash preventing loading of later font handlers.
104 https://rt.cpan.org/Ticket/Display.html?id=62855
106 - parse defines from the options returned by pkg-config --cflags
107 https://rt.cpan.org/Ticket/Display.html?id=63223
109 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
110 included in the tarball. They are now included.
112 Imager 0.78 - 4 Oct 2010
117 - don't access deprecated members of the png_structp.
118 https://rt.cpan.org/Ticket/Display.html?id=60242
120 - document that using color objects is faster than supplying colors
122 https://rt.cpan.org/Ticket/Display.html?id=61047
124 - Imager::Probe now accepts array references for incpath and libpath.
125 https://rt.cpan.org/Ticket/Display.html?id=60244
127 Imager 0.77_02 - 27 Sep 2010
130 - moved Win32, FreeType 2 font support into sub-modules.
131 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
132 Uses Imager::Probe now.
133 https://rt.cpan.org/Public/Bug/Display.html?id=61328
135 - tested successfully with jpeg-8b
136 https://rt.cpan.org/Ticket/Display.html?id=60221
140 - from _01: look for missing file support test files in the right
143 - flood_fill() wouldn't fill the right side of a single scan-line
145 Thanks to Nicolas Roggli for reporting this.
147 - flood_fill wouldn't fill to the left edge of the image if the
148 starting line didn't reach the left edge.
149 Thanks to Nicolas Roggli for reporting this.
151 Imager 0.77_01 - 13 Sep 2010
154 - add each library-directory/pkgconfig/ to the pkg-config search path
156 Thanks to Justin Davis.
157 https://rt.cpan.org/Ticket/Display.html?id=60491
159 - moved GIF, TIFF, JPEG file handling code into sub-modules in
160 preparation for separate distribution.
161 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
163 - optimize filled box drawing (color, not fill)
167 - Imager::Probe was calling ExtUtils::Liblist to initialize
168 LD_RUN_PATH supplying an undefined value rather than the found
169 directory. Thanks to Justin Davis.
170 https://rt.cpan.org/Ticket/Display.html?id=60491
172 - only prepend ./ to font filenames when passing them to T1Lib and
173 then only when it would use its search mechanisms.
174 https://rt.cpan.org/Ticket/Display.html?id=60509
176 - fix the cache check for the X rgb.txt loader. This is typically
177 used for color translation on Unix-like systems, and the fix
178 improves performance of supplying colors by name by about 80 times.
179 Test code that managed 3400 10x10 pixel boxes/second sped up to
182 - clarify that Imager doesn't write EXIF metadata to images.
183 https://rt.cpan.org/Ticket/Display.html?id=60637
185 - Imager::Probe can now search subdirectories under its include path.
186 Used by the PNG Makefile.PL to find headers and libraries when they
187 aren't in the base directory, as in cygwin.
188 https://rt.cpan.org/Ticket/Display.html?id=60635
190 Imager 0.77 - 11 Aug 2010
193 I don't want Imager::File::PNG indexed as part of Imager, but forgot
194 to update the META.yml before updating the version.
196 - don't index Imager::File::PNG as part of Imager
198 - add resources to META.yml
200 Imager 0.76 - not released
205 - the align_string() method would ignore a string of "0" due to a
207 Thanks to Maurice Height for reporting this.
208 https://rt.cpan.org/Ticket/Display.html?id=60199
210 Imager 0.75_03 - 09 Aug 2010
215 - read_types() and write_types() would include png when it wasn't
216 available due to a problem with the %formats tie
218 - handle dependent libraries correctly (eg -lpng requiring -lz) in
219 the code run phase of library probing.
221 Imager 0.75_02 - 07 Aug 2010
226 - add file missing from MANIFEST, which was causing TIFF failures.
228 Imager 0.75_01 - 06 Aug 2010
231 Test release for the new PNG probe.
233 - added the ability to read multiple-image PNM files.
234 Note that unlike the pbm/pgm/ppm specification this accepts mixed
235 format files and allows white space padding between files.
236 Thanks to Philip Gwyn (Leolo) for this patch.
238 - moved the PNG file handling code into a sub-module in preparation
239 for separate distribution.
240 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
241 Also helps avoid complications from -I/-L compile/link options from
246 - Imager->new(data => $data) didn't try to process image file data in
248 https://rt.cpan.org/Ticket/Display.html?id=58761
250 - t/t50basicoo.t no longer depends on the other tests to generate its
252 https://rt.cpan.org/Ticket/Display.html?id=9798
253 Also, it wasn't testing pnm (pnm vs ppm mix-up)
255 - update the documentation of hardinvert to match the change in 0.62.
256 https://rt.cpan.org/Ticket/Display.html?id=59785
258 - added hardinvertall filter which also inverts the alpha channel
261 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
262 the probe can find the library for the test run.
263 https://rt.cpan.org/Ticket/Display.html?id=57518
265 Imager 0.75 - 20 Jun 2010
268 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
273 - an opacity fill based on a fountain fill would segfault when
274 filling an 8-bit/sample image.
276 - merge thickline branch polygon fix
277 https://rt.cpan.org/Ticket/Display.html?id=43518
279 Imager 0.74 - 7 May 2010
284 - read_multi() didn't handle a missing file format library correctly,
285 aborting on failing to call i_readgif_multi_wiol() or
286 i_readtiff_multi_wiol().
288 - fix spelling errors patched by Debian
289 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
291 - add an (unshipped) author test to spellcheck Imager's POD.
293 - update the TIFF file format documentation
294 https://rt.cpan.org/Ticket/Display.html?id=56510
296 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
298 Imager 0.73 - 15 Mar 2010
301 - implement outline circles, both anti-aliased and not
302 https://rt.cpan.org/Ticket/Display.html?id=19755
304 - a combine => "none" fill to a 1 or 3 channel image would produce
305 the incorrect colour.
307 Imager 0.72 - 09 Dec 2009
310 Bump version for release, since 0.71_03 is stable with CPAN testers.
312 Imager 0.71_03 - 5 Dec 2009
315 - further adjust the threads test so it only performs the tests on
316 perls where it's expected to work, and only if the threads module
319 Imager 0.71_02 - 1 Dec 2009
322 - adjust the way we load the threads module for the threads test so
323 it works with non-threaded perls
325 Imager 0.71_01 - 30 Nov 2009
330 - use scanline oriented operations to flip images instead of pixel
332 https://rt.cpan.org/Ticket/Display.html?id=39278
334 - use double/sample operations to flip large sample images instead of
335 8-bit sample operations.
336 https://rt.cpan.org/Ticket/Display.html?id=39280
339 https://rt.cpan.org/Ticket/Display.html?id=51874
341 - prevent double-frees when someone creates Imager objects and then
342 creates a thread. Note: this just handles some simple cases,
343 Imager doesn't support perl threads, and isn't likely to.
344 https://rt.cpan.org/Ticket/Display.html?id=52268
346 Imager 0.71 - 16 Nov 2009
349 - add the opacity fill type - an adaptor that modifies the opacity of
354 - the conv filter now enforces that the sum of the coefficients is
355 non-zero. Also, rather than skipping pixels off the edge off the
356 edge of the image, the closest edge pixel is used. Previously
357 dividing by the zero sum of coefficients could cause invalid
358 results or runtime exceptions.
359 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
362 Imager 0.70 - 21 Sep 2009
367 - release image row and comments memory on all error returns in gif
370 - handle zero length extensions, previously this would cause a null
372 Thanks to Krzysztof Wojtaś for the test data and fix for this.
374 - an integer division meant that preview scaling to below 1 pixel
375 wide or high (which isn't too useful anyway) was calculating using
376 NaNs on most platforms, and causing an exception on others.
377 Thanks to David Cantrell for producing a backtrace of the crash on
378 his Alpha-NetBSD CPAN test box which made it possible to track this
381 Imager 0.69 - 08 Sep 2009
386 - broken test fix - was attempting to call a function skip_all, when
387 that should be a parameter to plan().
389 - briefly document apidocs.perl, the tool used to build
390 Imager::APIRef and make some minor enhancements
392 - various minor documentation enhancements and fixes.
394 Imager 0.68 - 07 Sep 2009
397 - Imager->new(file => $filename) and other similar incantations will
399 https://rt.cpan.org/Ticket/Display.html?id=48261
403 - avoid using CHECK as a label in Imager::Test
404 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
406 - re-work most image file test files that require a library into
407 separate library present/not present files to remove stupidly long
410 - don't treat rubthrough() outside the bounds of the target image as
412 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
414 Imager 0.67_01 - 02 Sep 2009
419 - correct documentation of default of raw image interleave read
421 https://rt.cpan.org/Ticket/Display.html?id=42074
423 - add raw_ prefix to raw read parameters, though the original names
426 - fail the read if an invalid raw_interleave parameter is supplied
428 - warn if no interleave or raw_interleave parameter is supplied,
429 since the documented default was wrong, and incompatible with the
432 - for reading raw images, if raw_storechannels > raw_datachannels,
433 set the extra channels in the image to 0
435 - when probing for executables like freetype-config, search for .bat
436 and .cmd on MSWin32, as well as .exe.
437 https://rt.cpan.org/Ticket/Display.html?id=49275
439 - re-work the external libraries section of README:
440 - list Debian and Redhat package names for each library
444 - use the new EU::MM META_MERGE facility instead of generating
445 META.yml from scratch
446 https://rt.cpan.org/Ticket/Display.html?id=47888
448 - use Devel::CheckLib (bundled, modified) to check which release of
449 libtiff is installed and reject 3.9.0
450 http://bugzilla.maptools.org/show_bug.cgi?id=2088
451 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
453 Imager 0.67 - 12 Dec 2008
458 - fix a packaging error
460 Imager 0.66 - 12 Dec 2008
463 - 24-bit color .ICO/.CUR files can now be read.
467 - an optimization skipping 0 src alpha values could cause the
468 rubthrough() to read past the end of a buffer.
469 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
471 - corrected a reference leak where writing GIFs would leak memory.
472 This could also happen calling to_paletted().
473 Also documented the underlying long existing feature where the
474 colors parameter is filled with the generated color table and added
476 http://rt.cpan.org/Ticket/Display.html?id=41028
478 - write out the image size in bytes field of a BMP correctly.
479 http://rt.cpan.org/Ticket/Display.html?id=41406
481 - add limited tests for Imager::ExtUtils
483 - make Imager::ExtUtils->includes use an absolute path, since
484 a relative path could cause failures using Inline::C.
485 http://rt.cpan.org/Ticket/Display.html?id=37353
487 - re-arrange the POD for Imager::Font::BBox:
488 - mark total_width(), pos_width(), end_offset() obsolete, since
489 they're mostly for backwards compatibility
490 - group width methods and height methods
491 https://rt.cpan.org/Ticket/Display.html?id=39999
493 Imager 0.65 - 20 May 2008
498 - In some cases when an error occurs reading those parts of a JPEG
499 file after the image the scan-line buffer could be freed a second
500 time. In cases where the the error occured while reading the image
501 data it's possible that the buffer could have leaked.
502 Thanks to Gabriel Vasseur for reporting this and help in tracking
505 - the gif_screen_height tag was overriding the screen width and being
506 ignored for the screen height when present.
507 https://rt.cpan.org/Public/Bug/Display.html?id=35568
509 Imager 0.64 - 23 April 2008
512 This is a bug fix release. This includes a fix for a possible
517 - Possible security issue: The floating point sample path for image
518 based fills had a buffer overflow. This would overwrite the end of
519 a malloc()ed buffer with double precision floats.
520 http://rt.cpan.org/Ticket/Display.html?id=35324
523 - check that the result of fileno($fh) is defined rather than simply
524 true when read() or write() is supplied with an fh parameter.
525 http://rt.cpan.org/Ticket/Display.html?id=35139
527 - i_scale_axis() wasn't checking the result of i_img_new_ch()
528 resulting in a SIGSEGV when attempting to scale an image to a size
529 too large to fit in memory. This is a NULL pointer access issue,
530 not a buffer overflow.
531 Added a check for the failure.
532 scale_calculate() (and hence scale()) will now fail if any of the
533 scale size parameters are a reference.
534 http://rt.cpan.org/Ticket/Display.html?id=35172
536 - Regression: filling a greyscale image with a hatch used the wrong
537 color channels from the supplied fg/bg colors.
538 https://rt.cpan.org/Ticket/Display.html?id=35278
540 - fixed a related problem for image fills.
542 Imager 0.63 - 7 April 2008
545 This release primarily contains changes to improve ease of use -
546 rather than you having to convert images to the appropriate number of
547 channels, Imager handles it internally. How to handle drawing colors
548 and the default combine mode is a thornier problem left for some other
551 - the font libraries are now only initialized when needed.
552 http://rt.cpan.org/Ticket/Display.html?id=28825
554 - moved the imtoc.perl code into Imager::Preprocess
556 - paste() and rubthrough() now adapt the source image data to the
557 destination, so you can now safely paste/rubthrough from greyscale
558 images to color images or back, or from alpha channel images to
559 noalpha channels or back.
560 https://rt.cpan.org/Ticket/Display.html?id=30908
562 - rubthrough() now falls back to pasting when the source doesn't have
563 an alpha channel. This effectively treats the source as having a
564 max alpha channel, the right thing to do.
565 http://rt.cpan.org/Ticket/Display.html?id=29944
567 - re-worked most of the area filling code to use a common set of
568 functions when filling.
569 Corrected normal combine mode.
570 Rewrote most of the combine modes to match the way the SVG draft
571 defines them with respect to a translucent source and destination.
572 Added tests for translucent source and destination.
573 Added tests to check 8-bit/sample and double/sample combines work
575 https://rt.cpan.org/Ticket/Display.html?id=29879
577 - writing a 2 or 4 channel image to a JPEG file will now write that
578 image as if composited against a background, black by default,
579 overridable with the i_background tag/parameter.
580 https://rt.cpan.org/Ticket/Display.html?id=29876
582 - writing a 2 or 4 channel image to a PGM/PPM file will now write
583 that image as if composited against a background, black by default,
584 overridable with the i_background tag/parameter.
585 http://rt.cpan.org/Ticket/Display.html?id=30074
587 - writing a 2 or 4 channel image to a BMP file will now write that
588 image as if composited against a background, black by default,
589 overridable with the i_background tag/parameter.
590 http://rt.cpan.org/Ticket/Display.html?id=30075
594 - Imager::Matrix2d->translate() now only requires one of the x or y
596 http://rt.cpan.org/Ticket/Display.html?id=29937
598 - mixing qtype scaling now sets all channels of a pixel to zero if
599 the pixel has zero coverage (zero alpha). This should produce more
600 compressible output files.
601 http://rt.cpan.org/Ticket/Display.html?id=32324
603 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
605 https://bugzilla.redhat.com/show_bug.cgi?id=166254
606 I'm not changing the #! lines of the sample code, since it's sample
607 code, not intended for installation.
608 http://rt.cpan.org/Ticket/Display.html?id=33408
610 - some TGA images weren't being detected correctly as TGA images
611 https://rt.cpan.org/Ticket/Display.html?id=32925
613 - handling of the left-over bit for 16-bit/pixel TGA images has been
614 changed to match the behaviour of the GIMP. Previously the bit
615 being set was treated as an opaque pixel, but one user reported a
616 problem with loading such an image. I haven't been able to find any
617 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
618 I'll match it's behaviour. See issue 114913 in the GIMP's
620 http://rt.cpan.org/Ticket/Display.html?id=32926
622 Imager 0.62 - 10 December 2007
625 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
626 to /path under your home directory.
627 http://rt.cpan.org/Ticket/Display.html?id=29484
629 - the old dynaload code used Mach API functions to load dynamic
630 libraries on Mac OS X. These APIs have been deprecated in OS X
631 10.5 and were causing some build problems.
632 So henceforth Imager uses the dlopen() family of functions, and you
633 will need version 10.3 or later of OS X.
635 - added the det() function to the transform2() engine.
636 added the sample quad_to_square.pl
637 Courtesy Richard Fairhurst.
638 http://rt.cpan.org/Ticket/Display.html?id=31244
642 - samples/gifscale.pl sourced the base value for gif_top from
644 Thanks to Eleneldil G. Arilou for pointing this out.
646 - t/t82inline.t no longer loads B at runtime, to work around a bug
647 in some 5.005_0[45] installations.
648 http://rt.cpan.org/Ticket/Display.html?id=30508
650 - work around Module::Depends::Intrusive bug #21229
651 http://rt.cpan.org/Ticket/Display.html?id=30520
653 - the hardinvert filter no-longer inverts the alpha channel.
654 http://rt.cpan.org/Ticket/Display.html?id=30002
656 - the hardinvert filter now supports large samples
658 Imager 0.61_02 - 28 November 2007
661 - major TIFF support re-work
662 http://rt.cpan.org/Ticket/Display.html?id=20329
664 - added a C level image interface for accessing samples from 1-32
665 bits, exposed this at the perl level in getsamples()
667 - the conv filter now works at floating point precision for high bit
670 - added is_bilevel method to test whether an image should be written as
671 a bilevel image if the image format supports it.
673 - added -log-stderr as an Imager import list option
675 - added some important types to Imager::APIRef
677 - added test_image_double() to Imager::Test
681 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
684 - the scale() method with qtype mixing now handles images with an
685 alpha channel correctly.
687 - fixed a broken link from the "animated GIF" entry in the concept index.
688 Thanks to Slaven Rezic.
689 http://rt.cpan.org/Ticket/Display.html?id=30889
691 - on some perl's the infix expression parser test would fail due to
692 actions in the grammar returning false. Made sure all actions return
694 Thanks to Richard Fairhurst for spending a lot of time in tracking
696 http://rt.cpan.org/Public/Bug/Display.html?id=29562
698 Imager 0.61 - 5 November 2007
701 - added samples/gifscale.pl, which adjusts the screen size/position tags
702 when scaling an animated gif
703 http://rt.cpan.org/Ticket/Display.html?id=27591
707 - correct handling of sz in matrix_transform() - this should allow
708 perspective type transformations to work now.
709 http://rt.cpan.org/Ticket/Display.html?id=29936
711 - prevent a cast to integer warning on x64 builds in datatypes.c
712 also fixed some other type warnings
713 https://rt.cpan.org/Ticket/Display.html?id=30204
715 - some sub-directory tests depended on files produced by the parent
717 http://rt.cpan.org/Ticket/Display.html?id=30203
719 - Imager::Font::Wrap doesn't correctly set savepos
720 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
721 http://rt.cpan.org/Ticket/Display.html?id=29771
723 - test 171 in t/t01introvert.t was failing on perls configured to
725 http://rt.cpan.org/Ticket/Display.html?id=29413
727 - the code for the transform2() uminus operator was missing a break.
728 Added tests for better code coverage of the ops.
729 http://rt.cpan.org/Ticket/Display.html?id=29296
731 - the SGI RLE compression code could overflow its compression buffer
732 http://rt.cpan.org/Ticket/Display.html?id=30334
734 - the 32-bit output function used by the SGI code only handled values
735 under 0x10000. This was most noticable when writing large RLE images.
736 http://rt.cpan.org/Ticket/Display.html?id=30335
738 - validate chan_count for chans == NULL for each of the i_gsamp()
740 http://rt.cpan.org/Ticket/Display.html?id=28985
742 - attempt to work around the test failure at
743 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
744 http://rt.cpan.org/Ticket/Display.html?id=29562
746 - improve the error messages produced when attempting to read or write
747 an unknown image file format.
748 http://rt.cpan.org/Ticket/Display.html?id=30103
750 - improve the transform2() documentation
751 http://rt.cpan.org/Ticket/Display.html?id=29267
753 - correctly generate the author key in META.yml
754 http://rt.cpan.org/Ticket/Display.html?id=30377
756 - correctly blend a rotated (or matrix_transformed()) image when
757 performing interpolation in the presence of an alpha channel.
758 Also corrected the centring of the rotated image on the output
761 Imager 0.60 - 30 August 2007
764 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
765 now has full SGI RGB image format, including RLE and 16-bit/sample
767 https://rt.cpan.org/Ticket/Display.html?id=8666
769 - logging functions are now available in the API
771 - applied Gabriel Vasseur's patch
772 added documentation, further tests, and support for greyscale images
773 Obviously problems are my fault :)
774 https://rt.cpan.org/Ticket/Display.html?id=28142
776 - the mask for ICO/CUR images is now applied as an alpha channel to
777 the returned image. For the old behaviour, supply ico_masked => 0
778 to read() or read_multi(). This should be less confusing when
779 using Imager as a general image processor.
780 https://rt.cpan.org/Ticket/Display.html?id=29001
784 - in some cases it's possible for giflib/libungif to return color
785 indexes outside the range of colors defined by the image's palette.
786 We now expand the palette to match the indexes used.
787 Thanks to Gabriel Vasseur for reporting this.
789 - fixed various memory leaks that could occur when failing to read png,
790 jpeg, bmp or tga files.
792 - to avoid confusion, channels not present in the image are returned as
793 zero by getscanline(). This has no effect on the C level i_glin()
794 and i_glinf() API functions which continue to not set the unused
797 - the convert() method now returns an image of the same sample size as
799 https://rt.cpan.org/Ticket/Display.html?id=28492
801 - remove repeated text in Imager::Files
802 http://rt.cpan.org/Ticket/Display.html?id=27589
804 - be even more explicit that scale() and friends don't modify the source
805 image, but return a new image.
806 http://rt.cpan.org/Ticket/Display.html?id=28570
808 - improve the error message from errstr() when you try to load a font
809 for which the driver hasn't been built in Imager.
810 http://rt.cpan.org/Ticket/Display.html?id=27571
812 - transparency is now enabled by default when writing GIF images
813 http://rt.cpan.org/Ticket/Display.html?id=27615
815 - Imager would not load on Windows 98
816 http://rt.cpan.org/Ticket/Display.html?id=27653
818 Imager 0.59 - 14 June 2007
823 - fixes a regression introduced by the fixes for RT 11972
824 http://rt.cpan.org/Ticket/Display.html?id=27546
826 - cropping outside the image would return an Imager object with
827 no low-level image object, instead of returning false.
828 Fixed by: Philip Gwyn (Leolo)
829 http://rt.cpan.org/Ticket/Display.html?id=27509
831 Imager 0.58 - 16 May 2007
834 No significant changes from 0.57_01.
836 Imager 0.57_01 - 11 May 2007
839 - added to_rgb16 to produce a 16-bit/sample version of an image
841 - improve freetype 1.x text output efficiency
845 - search another place for rgb.txt, and check all the places
846 Imager::Color checks when deciding whether to skip testing it
847 http://rt.cpan.org/Ticket/Display.html?id=26064
849 - use a convolution kernel size based on the stddev rather than a
850 fixed size when performing a gaussian blur
851 http://rt.cpan.org/Ticket/Display.html?id=25645
853 - document the difference() method's mindist parameter, and debug it.
855 - put the Imager release number in the Inline::C generated code to
856 regenerate Inline code when a new release of Imager is installed.
857 http://rt.cpan.org/Ticket/Display.html?id=26278
859 - fix rendering on alpha channel images for the FreeType 1.x driver.
860 http://rt.cpan.org/Ticket/Display.html?id=11972
862 - fix rendering on alpha channel images for the T1lib driver.
863 http://rt.cpan.org/Ticket/Display.html?id=11972
865 - reworked library probing, we can now set more than one probe
866 function for a library. Disabled the default (non-freetype-config)
867 library probe and added an extra probe function that searches for
868 both ft2build.h and whatever it includes, and adds -I as needed.
869 Hopefully this will fix build problems like
870 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
871 http://rt.cpan.org/Ticket/Display.html?id=26086
873 Imager 0.57 - 30 Apr 2007
876 This is a maintenence release fixing a security issue in Imager.
878 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
879 overflow in malloced memory. There will be further discussion of
880 this issue in the ticket below.
881 http://rt.cpan.org/Ticket/Display.html?id=26811
882 CVE-2007-2459 CVE-2007-2413
883 The descriptions at cve.mitre.org varied in quality, please see the
884 ticket at rt.cpan.org for a more accurate description of the issue.
886 Imager 0.56 - 1 Apr 2007
889 - added support for reading 16-bit/sample PGM/PPM images
891 - added support for writing 16-bit/sample PGM/PPM images
893 - improved performance of reading PBM/PGM/PPM images
895 - added support for writing PBM images if the image is paletted and
896 contains only black and white
898 - added a new make_colors value - "mono"
900 - switched from the svn log Changes to a manual Changes to reduce
903 - new sample code - samples/flasher.pl
907 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
908 was returning an image object with an extra reference, this
909 resulted in a memory leak.
910 http://rt.cpan.org/Ticket/Display.html?id=24992
912 - fix rendering on alpha channel images for the FreeType 2.x driver
913 http://rt.cpan.org/Ticket/Display.html?id=11972
915 - reading bmp files now consitently handles short reads. You can now
916 supply a parameter to treat a short read as successful and set
918 http://rt.cpan.org/Ticket/Display.html?id=8426
920 - previously, reading ASCII PBM files required spaces between samples,
921 even though the format doesn't require that
923 - improved documentation of the unsharpmask filter (I hope)
924 http://rt.cpan.org/Ticket/Display.html?id=25531
926 - force flushing of the output from i_tt_dump_names() and test output
927 in t/t35ttfont.t to prevent output from being mixed up.
928 https://rt.cpan.org/Ticket/Display.html?id=24859
930 - rewrite a conditional expression as an if() to hopefully work around
931 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
932 https://rt.cpan.org/Ticket/Display.html?id=25561
934 - avoid Data::Dumper in regops.perl to support older releases of perl
935 https://rt.cpan.org/Ticket/Display.html?id=24391
937 Imager 0.55 - 16 Dec 2006
940 This is primarily a bug fix release.
942 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
944 There is one new feature:
946 - the Win32 font driver now supports UTF8 (RT 22166)
947 http://www.cpanforum.com/threads/3276
948 http://rt.cpan.org/Ticket/Display.html?id=22166
950 Several bugs were fixed:
952 - the string() method would not output the string "0"
953 http://rt.cpan.org/Public/Bug/Display.html?id=21770
955 - fills.c was failing to compile on Solaris 10 (compiler unknown)
956 http://rt.cpan.org/Public/Bug/Display.html?id=21944
958 - the gif_disposal and gif_user_input tags weren't being read from
960 http://rt.cpan.org/Public/Bug/Display.html?id=22192
962 - gif.c was failing to build under MSVC
963 http://rt.cpan.org/Ticket/Display.html?id=23922
965 - in some cases strings passed to the string() method were treated as
966 terminated by NUL (chr 0)
967 http://rt.cpan.org/Public/Bug/Display.html?id=21770
969 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
970 that's the default build name for zlib on Win32.
971 http://rt.cpan.org/Ticket/Display.html?id=23064
973 - search $Config{incpath} for headers too, which we should have been
976 Win32 font driver fixes:
978 - the global descent value from bounding box was the wrong sign
979 http://www.cpanforum.com/threads/3276
981 - if the first or last glyph overflowed the left or right side of the
982 advance width they would be clipped
985 Imager 0.54 - 14 Sep 2006
988 This is primarily a feature release:
990 - a new qtype value 'mixing' has been added to the scale()
991 method. This is faster than 'normal', slower than 'preview'. This
992 is based on the method used by pnmscale, and seems to produce less
993 blurry results than normal.
994 http://rt.cpan.org/Public/Bug/Display.html?id=20677
996 - the rubthrough() method can now render onto images with an alpha
998 http://rt.cpan.org/Ticket/Display.html?id=20678
1000 - the read_multi() method now falls back to calling doing a single
1001 image read via the read() method and write_multi() will now fall
1002 back to calling write() if a single image is supplied. This means
1003 you can simply call the read_multi() or write_multi() functions
1004 without having to check if the type is formatted by that method.
1005 http://rt.cpan.org/Ticket/Display.html?id=19457
1006 http://rt.cpan.org/Ticket/Display.html?id=19458
1008 - the GIF loop extension can now be written. If you don't have
1009 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1011 http://rt.cpan.org/Ticket/Display.html?id=21185
1013 - getscanline() and setscanline() can now read/write palette index
1014 based data from/to the image for paletted images, by setting type to
1016 http://rt.cpan.org/Ticket/Display.html?id=20338
1018 - we no longer hassle you to disable GIF support
1019 http://rt.cpan.org/Ticket/Display.html?id=20687
1021 - minor documentation fixes
1024 Imager 0.53 - 26 Jul 2006
1027 This is a bugfix release.
1029 Some test code was left in a code path not covered by the test
1030 suite. A test was added to cover this code path and the test code was
1032 http://rt.cpan.org/Public/Bug/Display.html?id=20705
1035 Imager 0.52 - 25 Jul 2006
1038 This is primarily a feature release, but contains a fair few bug
1039 fixes, new features:
1041 - ability to read and write MS Windows ICO and CUR files
1043 - you can now add file format plugins to support new file formats
1045 - add POD coverage tests
1047 - setcolors() and addcolors() now accept color names and so on
1048 instead of requiring Imager::Color objects.
1049 http://rt.cpan.org/Ticket/Display.html?id=20056
1051 - flood_fill() can now fill to a specified border color instead of
1052 just to the area the same color as the seed.
1053 http://rt.cpan.org/Ticket/Display.html?id=19618
1058 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1059 calculating the advance width.
1060 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1062 - bounding_box for the T1 driver wasn't including leading and
1063 trailing spaces in the bounding box as the other drivers did, it also
1064 produced strange results for empty strings or strings containing only
1067 - when reading CMYK jpeg images they were being transferred to the
1068 image object as is, producing a four channel image. It only looked ok
1069 due to an old still unfixed Photoshop bug. We now convert from the
1070 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1071 http://rt.cpan.org/Ticket/Display.html?id=20416
1073 - reading a CYMK TIFF would result in a 4 channel image, reading any
1074 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1076 http://rt.cpan.org/Ticket/Display.html?id=20415
1078 - added /usr/local/include to the default include search path, since
1079 we were already searching /usr/local/lib for libraries.
1081 And various minor fixes and documentation updates.
1084 Imager 0.51 - 23 Apr 2006
1087 - fix a validation bug when processing JPEG EXIF data that can cause
1089 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1091 - fix mis-processing of the src_maxx and src_maxy parameters of the
1093 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1095 - fix a problem in Imager's "smart" handling of the color parameter
1097 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1100 Imager 0.50 - 29 Mar 2006
1103 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1104 or 4 channel image to jpeg or a 2 channel image to tga where the
1105 output is an in-memeory buffer.
1106 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1108 - fixes an incorrect pointer parameter in the PNG code
1109 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1111 - skip Inline::C tests when building in a directory with spaces
1112 http://rt.cpan.org/Public/Bug/Display.html?id=18049
