1 Imager release history. Older releases can be found in Changes.old
3 Imager 0.78 - unreleased
6 - add each library-directory/pkgconfig/ to the pkg-config search path
8 Thanks to Justin Davis.
9 https://rt.cpan.org/Ticket/Display.html?id=60491
11 - moved GIF, TIFF, JPEG file handling code into sub-modules in
12 preparation for separate distribution.
13 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
15 - optimize filled box drawing (color, not fill)
19 - Imager::Probe was calling ExtUtils::Liblist to initialize
20 LD_RUN_PATH supplying an undefined value rather than the found
21 directory. Thanks to Justin Davis.
22 https://rt.cpan.org/Ticket/Display.html?id=60491
24 - only prepend ./ to font filenames when passing them to T1Lib and
25 then only when it would use its search mechanisms.
26 https://rt.cpan.org/Ticket/Display.html?id=60509
28 - fix the cache check for the X rgb.txt loader. This is typically
29 used for color translation on Unix-like systems, and improves
30 performance of supplying colors by name by about 80 times. Test
31 code that managed 3400 10x10 pixel boxes/second sped up to 25700
34 Imager 0.77 - 11 Aug 2010
37 I don't want Imager::File::PNG indexed as part of Imager, but forgot
38 to update the META.yml before updating the version.
40 - don't index Imager::File::PNG as part of Imager
42 - add resources to META.yml
44 Imager 0.76 - not released
49 - the align_string() method would ignore a string of "0" due to a
51 Thanks to Maurice Height for reporting this.
52 https://rt.cpan.org/Ticket/Display.html?id=60199
54 Imager 0.75_03 - 09 Aug 2010
59 - read_types() and write_types() would include png when it wasn't
60 available due to a problem with the %formats tie
62 - handle dependent libraries correctly (eg -lpng requiring -lz) in
63 the code run phase of library probing.
65 Imager 0.75_02 - 07 Aug 2010
70 - add file missing from MANIFEST, which was causing TIFF failures.
72 Imager 0.75_01 - 06 Aug 2010
75 Test release for the new PNG probe.
77 - added the ability to read multiple-image PNM files.
78 Note that unlike the pbm/pgm/ppm specification this accepts mixed
79 format files and allows white space padding between files.
80 Thanks to Philip Gwyn (Leolo) for this patch.
82 - moved the PNG file handling code into a sub-module in preparation
83 for separate distribution.
84 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
85 Also helps avoid complications from -I/-L compile/link options from
90 - Imager->new(data => $data) didn't try to process image file data in
92 https://rt.cpan.org/Ticket/Display.html?id=58761
94 - t/t50basicoo.t no longer depends on the other tests to generate its
96 https://rt.cpan.org/Ticket/Display.html?id=9798
97 Also, it wasn't testing pnm (pnm vs ppm mix-up)
99 - update the documentation of hardinvert to match the change in 0.62.
100 https://rt.cpan.org/Ticket/Display.html?id=59785
102 - added hardinvertall filter which also inverts the alpha channel
105 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
106 the probe can find the library for the test run.
107 https://rt.cpan.org/Ticket/Display.html?id=57518
109 Imager 0.75 - 20 Jun 2010
112 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
117 - an opacity fill based on a fountain fill would segfault when
118 filling an 8-bit/sample image.
120 - merge thickline branch polygon fix
121 https://rt.cpan.org/Ticket/Display.html?id=43518
123 Imager 0.74 - 7 May 2010
128 - read_multi() didn't handle a missing file format library correctly,
129 aborting on failing to call i_readgif_multi_wiol() or
130 i_readtiff_multi_wiol().
132 - fix spelling errors patched by Debian
133 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
135 - add an (unshipped) author test to spellcheck Imager's POD.
137 - update the TIFF file format documentation
138 https://rt.cpan.org/Ticket/Display.html?id=56510
140 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
142 Imager 0.73 - 15 Mar 2010
145 - implement outline circles, both anti-aliased and not
146 https://rt.cpan.org/Ticket/Display.html?id=19755
148 - a combine => "none" fill to a 1 or 3 channel image would produce
149 the incorrect colour.
151 Imager 0.72 - 09 Dec 2009
154 Bump version for release, since 0.71_03 is stable with CPAN testers.
156 Imager 0.71_03 - 5 Dec 2009
159 - further adjust the threads test so it only performs the tests on
160 perls where it's expected to work, and only if the threads module
163 Imager 0.71_02 - 1 Dec 2009
166 - adjust the way we load the threads module for the threads test so
167 it works with non-threaded perls
169 Imager 0.71_01 - 30 Nov 2009
174 - use scanline oriented operations to flip images instead of pixel
176 https://rt.cpan.org/Ticket/Display.html?id=39278
178 - use double/sample operations to flip large sample images instead of
179 8-bit sample operations.
180 https://rt.cpan.org/Ticket/Display.html?id=39280
183 https://rt.cpan.org/Ticket/Display.html?id=51874
185 - prevent double-frees when someone creates Imager objects and then
186 creates a thread. Note: this just handles some simple cases,
187 Imager doesn't support perl threads, and isn't likely to.
188 https://rt.cpan.org/Ticket/Display.html?id=52268
190 Imager 0.71 - 16 Nov 2009
193 - add the opacity fill type - an adaptor that modifies the opacity of
198 - the conv filter now enforces that the sum of the coefficients is
199 non-zero. Also, rather than skipping pixels off the edge off the
200 edge of the image, the closest edge pixel is used. Previously
201 dividing by the zero sum of coefficients could cause invalid
202 results or runtime exceptions.
203 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
206 Imager 0.70 - 21 Sep 2009
211 - release image row and comments memory on all error returns in gif
214 - handle zero length extensions, previously this would cause a null
216 Thanks to Krzysztof WojtaÅ for the test data and fix for this.
218 - an integer division meant that preview scaling to below 1 pixel
219 wide or high (which isn't too useful anyway) was calculating using
220 NaNs on most platforms, and causing an exception on others.
221 Thanks to David Cantrell for producing a backtrace of the crash on
222 his Alpha-NetBSD CPAN test box which made it possible to track this
225 Imager 0.69 - 08 Sep 2009
230 - broken test fix - was attempting to call a function skip_all, when
231 that should be a parameter to plan().
233 - briefly document apidocs.perl, the tool used to build
234 Imager::APIRef and make some minor enhancements
236 - various minor documentation enhancements and fixes.
238 Imager 0.68 - 07 Sep 2009
241 - Imager->new(file => $filename) and other similar incantations will
243 https://rt.cpan.org/Ticket/Display.html?id=48261
247 - avoid using CHECK as a label in Imager::Test
248 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
250 - re-work most image file test files that require a library into
251 separate library present/not present files to remove stupidly long
254 - don't treat rubthrough() outside the bounds of the target image as
256 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
258 Imager 0.67_01 - 02 Sep 2009
263 - correct documentation of default of raw image interleave read
265 https://rt.cpan.org/Ticket/Display.html?id=42074
267 - add raw_ prefix to raw read parameters, though the original names
270 - fail the read if an invalid raw_interleave parameter is supplied
272 - warn if no interleave or raw_interleave parameter is supplied,
273 since the documented default was wrong, and incompatible with the
276 - for reading raw images, if raw_storechannels > raw_datachannels,
277 set the extra channels in the image to 0
279 - when probing for executables like freetype-config, search for .bat
280 and .cmd on MSWin32, as well as .exe.
281 https://rt.cpan.org/Ticket/Display.html?id=49275
283 - re-work the external libraries section of README:
284 - list Debian and Redhat package names for each library
288 - use the new EU::MM META_MERGE facility instead of generating
289 META.yml from scratch
290 https://rt.cpan.org/Ticket/Display.html?id=47888
292 - use Devel::CheckLib (bundled, modified) to check which release of
293 libtiff is installed and reject 3.9.0
294 http://bugzilla.maptools.org/show_bug.cgi?id=2088
295 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
297 Imager 0.67 - 12 Dec 2008
302 - fix a packaging error
304 Imager 0.66 - 12 Dec 2008
307 - 24-bit color .ICO/.CUR files can now be read.
311 - an optimization skipping 0 src alpha values could cause the
312 rubthrough() to read past the end of a buffer.
313 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
315 - corrected a reference leak where writing GIFs would leak memory.
316 This could also happen calling to_paletted().
317 Also documented the underlying long existing feature where the
318 colors parameter is filled with the generated color table and added
320 http://rt.cpan.org/Ticket/Display.html?id=41028
322 - write out the image size in bytes field of a BMP correctly.
323 http://rt.cpan.org/Ticket/Display.html?id=41406
325 - add limited tests for Imager::ExtUtils
327 - make Imager::ExtUtils->includes use an absolute path, since
328 a relative path could cause failures using Inline::C.
329 http://rt.cpan.org/Ticket/Display.html?id=37353
331 - re-arrange the POD for Imager::Font::BBox:
332 - mark total_width(), pos_width(), end_offset() obsolete, since
333 they're mostly for backwards compatibility
334 - group width methods and height methods
335 https://rt.cpan.org/Ticket/Display.html?id=39999
337 Imager 0.65 - 20 May 2008
342 - In some cases when an error occurs reading those parts of a JPEG
343 file after the image the scan-line buffer could be freed a second
344 time. In cases where the the error occured while reading the image
345 data it's possible that the buffer could have leaked.
346 Thanks to Gabriel Vasseur for reporting this and help in tracking
349 - the gif_screen_height tag was overriding the screen width and being
350 ignored for the screen height when present.
351 https://rt.cpan.org/Public/Bug/Display.html?id=35568
353 Imager 0.64 - 23 April 2008
356 This is a bug fix release. This includes a fix for a possible
361 - Possible security issue: The floating point sample path for image
362 based fills had a buffer overflow. This would overwrite the end of
363 a malloc()ed buffer with double precision floats.
364 http://rt.cpan.org/Ticket/Display.html?id=35324
367 - check that the result of fileno($fh) is defined rather than simply
368 true when read() or write() is supplied with an fh parameter.
369 http://rt.cpan.org/Ticket/Display.html?id=35139
371 - i_scale_axis() wasn't checking the result of i_img_new_ch()
372 resulting in a SIGSEGV when attempting to scale an image to a size
373 too large to fit in memory. This is a NULL pointer access issue,
374 not a buffer overflow.
375 Added a check for the failure.
376 scale_calculate() (and hence scale()) will now fail if any of the
377 scale size parameters are a reference.
378 http://rt.cpan.org/Ticket/Display.html?id=35172
380 - Regression: filling a greyscale image with a hatch used the wrong
381 color channels from the supplied fg/bg colors.
382 https://rt.cpan.org/Ticket/Display.html?id=35278
384 - fixed a related problem for image fills.
386 Imager 0.63 - 7 April 2008
389 This release primarily contains changes to improve ease of use -
390 rather than you having to convert images to the appropriate number of
391 channels, Imager handles it internally. How to handle drawing colors
392 and the default combine mode is a thornier problem left for some other
395 - the font libraries are now only initialized when needed.
396 http://rt.cpan.org/Ticket/Display.html?id=28825
398 - moved the imtoc.perl code into Imager::Preprocess
400 - paste() and rubthrough() now adapt the source image data to the
401 destination, so you can now safely paste/rubthrough from greyscale
402 images to color images or back, or from alpha channel images to
403 noalpha channels or back.
404 https://rt.cpan.org/Ticket/Display.html?id=30908
406 - rubthrough() now falls back to pasting when the source doesn't have
407 an alpha channel. This effectively treats the source as having a
408 max alpha channel, the right thing to do.
409 http://rt.cpan.org/Ticket/Display.html?id=29944
411 - re-worked most of the area filling code to use a common set of
412 functions when filling.
413 Corrected normal combine mode.
414 Rewrote most of the combine modes to match the way the SVG draft
415 defines them with respect to a translucent source and destination.
416 Added tests for translucent source and destination.
417 Added tests to check 8-bit/sample and double/sample combines work
419 https://rt.cpan.org/Ticket/Display.html?id=29879
421 - writing a 2 or 4 channel image to a JPEG file will now write that
422 image as if composited against a background, black by default,
423 overridable with the i_background tag/parameter.
424 https://rt.cpan.org/Ticket/Display.html?id=29876
426 - writing a 2 or 4 channel image to a PGM/PPM file will now write
427 that image as if composited against a background, black by default,
428 overridable with the i_background tag/parameter.
429 http://rt.cpan.org/Ticket/Display.html?id=30074
431 - writing a 2 or 4 channel image to a BMP file will now write that
432 image as if composited against a background, black by default,
433 overridable with the i_background tag/parameter.
434 http://rt.cpan.org/Ticket/Display.html?id=30075
438 - Imager::Matrix2d->translate() now only requires one of the x or y
440 http://rt.cpan.org/Ticket/Display.html?id=29937
442 - mixing qtype scaling now sets all channels of a pixel to zero if
443 the pixel has zero coverage (zero alpha). This should produce more
444 compressible output files.
445 http://rt.cpan.org/Ticket/Display.html?id=32324
447 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
449 https://bugzilla.redhat.com/show_bug.cgi?id=166254
450 I'm not changing the #! lines of the sample code, since it's sample
451 code, not intended for installation.
452 http://rt.cpan.org/Ticket/Display.html?id=33408
454 - some TGA images weren't being detected correctly as TGA images
455 https://rt.cpan.org/Ticket/Display.html?id=32925
457 - handling of the left-over bit for 16-bit/pixel TGA images has been
458 changed to match the behaviour of the GIMP. Previously the bit
459 being set was treated as an opaque pixel, but one user reported a
460 problem with loading such an image. I haven't been able to find any
461 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
462 I'll match it's behaviour. See issue 114913 in the GIMP's
464 http://rt.cpan.org/Ticket/Display.html?id=32926
466 Imager 0.62 - 10 December 2007
469 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
470 to /path under your home directory.
471 http://rt.cpan.org/Ticket/Display.html?id=29484
473 - the old dynaload code used Mach API functions to load dynamic
474 libraries on Mac OS X. These APIs have been deprecated in OS X
475 10.5 and were causing some build problems.
476 So henceforth Imager uses the dlopen() family of functions, and you
477 will need version 10.3 or later of OS X.
479 - added the det() function to the transform2() engine.
480 added the sample quad_to_square.pl
481 Courtesy Richard Fairhurst.
482 http://rt.cpan.org/Ticket/Display.html?id=31244
486 - samples/gifscale.pl sourced the base value for gif_top from
488 Thanks to Eleneldil G. Arilou for pointing this out.
490 - t/t82inline.t no longer loads B at runtime, to work around a bug
491 in some 5.005_0[45] installations.
492 http://rt.cpan.org/Ticket/Display.html?id=30508
494 - work around Module::Depends::Intrusive bug #21229
495 http://rt.cpan.org/Ticket/Display.html?id=30520
497 - the hardinvert filter no-longer inverts the alpha channel.
498 http://rt.cpan.org/Ticket/Display.html?id=30002
500 - the hardinvert filter now supports large samples
502 Imager 0.61_02 - 28 November 2007
505 - major TIFF support re-work
506 http://rt.cpan.org/Ticket/Display.html?id=20329
508 - added a C level image interface for accessing samples from 1-32
509 bits, exposed this at the perl level in getsamples()
511 - the conv filter now works at floating point precision for high bit
514 - added is_bilevel method to test whether an image should be written as
515 a bilevel image if the image format supports it.
517 - added -log-stderr as an Imager import list option
519 - added some important types to Imager::APIRef
521 - added test_image_double() to Imager::Test
525 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
528 - the scale() method with qtype mixing now handles images with an
529 alpha channel correctly.
531 - fixed a broken link from the "animated GIF" entry in the concept index.
532 Thanks to Slaven Rezic.
533 http://rt.cpan.org/Ticket/Display.html?id=30889
535 - on some perl's the infix expression parser test would fail due to
536 actions in the grammar returning false. Made sure all actions return
538 Thanks to Richard Fairhurst for spending a lot of time in tracking
540 http://rt.cpan.org/Public/Bug/Display.html?id=29562
542 Imager 0.61 - 5 November 2007
545 - added samples/gifscale.pl, which adjusts the screen size/position tags
546 when scaling an animated gif
547 http://rt.cpan.org/Ticket/Display.html?id=27591
551 - correct handling of sz in matrix_transform() - this should allow
552 perspective type transformations to work now.
553 http://rt.cpan.org/Ticket/Display.html?id=29936
555 - prevent a cast to integer warning on x64 builds in datatypes.c
556 also fixed some other type warnings
557 https://rt.cpan.org/Ticket/Display.html?id=30204
559 - some sub-directory tests depended on files produced by the parent
561 http://rt.cpan.org/Ticket/Display.html?id=30203
563 - Imager::Font::Wrap doesn't correctly set savepos
564 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
565 http://rt.cpan.org/Ticket/Display.html?id=29771
567 - test 171 in t/t01introvert.t was failing on perls configured to
569 http://rt.cpan.org/Ticket/Display.html?id=29413
571 - the code for the transform2() uminus operator was missing a break.
572 Added tests for better code coverage of the ops.
573 http://rt.cpan.org/Ticket/Display.html?id=29296
575 - the SGI RLE compression code could overflow its compression buffer
576 http://rt.cpan.org/Ticket/Display.html?id=30334
578 - the 32-bit output function used by the SGI code only handled values
579 under 0x10000. This was most noticable when writing large RLE images.
580 http://rt.cpan.org/Ticket/Display.html?id=30335
582 - validate chan_count for chans == NULL for each of the i_gsamp()
584 http://rt.cpan.org/Ticket/Display.html?id=28985
586 - attempt to work around the test failure at
587 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
588 http://rt.cpan.org/Ticket/Display.html?id=29562
590 - improve the error messages produced when attempting to read or write
591 an unknown image file format.
592 http://rt.cpan.org/Ticket/Display.html?id=30103
594 - improve the transform2() documentation
595 http://rt.cpan.org/Ticket/Display.html?id=29267
597 - correctly generate the author key in META.yml
598 http://rt.cpan.org/Ticket/Display.html?id=30377
600 - correctly blend a rotated (or matrix_transformed()) image when
601 performing interpolation in the presence of an alpha channel.
602 Also corrected the centring of the rotated image on the output
605 Imager 0.60 - 30 August 2007
608 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
609 now has full SGI RGB image format, including RLE and 16-bit/sample
611 https://rt.cpan.org/Ticket/Display.html?id=8666
613 - logging functions are now available in the API
615 - applied Gabriel Vasseur's patch
616 added documentation, further tests, and support for greyscale images
617 Obviously problems are my fault :)
618 https://rt.cpan.org/Ticket/Display.html?id=28142
620 - the mask for ICO/CUR images is now applied as an alpha channel to
621 the returned image. For the old behaviour, supply ico_masked => 0
622 to read() or read_multi(). This should be less confusing when
623 using Imager as a general image processor.
624 https://rt.cpan.org/Ticket/Display.html?id=29001
628 - in some cases it's possible for giflib/libungif to return color
629 indexes outside the range of colors defined by the image's palette.
630 We now expand the palette to match the indexes used.
631 Thanks to Gabriel Vasseur for reporting this.
633 - fixed various memory leaks that could occur when failing to read png,
634 jpeg, bmp or tga files.
636 - to avoid confusion, channels not present in the image are returned as
637 zero by getscanline(). This has no effect on the C level i_glin()
638 and i_glinf() API functions which continue to not set the unused
641 - the convert() method now returns an image of the same sample size as
643 https://rt.cpan.org/Ticket/Display.html?id=28492
645 - remove repeated text in Imager::Files
646 http://rt.cpan.org/Ticket/Display.html?id=27589
648 - be even more explicit that scale() and friends don't modify the source
649 image, but return a new image.
650 http://rt.cpan.org/Ticket/Display.html?id=28570
652 - improve the error message from errstr() when you try to load a font
653 for which the driver hasn't been built in Imager.
654 http://rt.cpan.org/Ticket/Display.html?id=27571
656 - transparency is now enabled by default when writing GIF images
657 http://rt.cpan.org/Ticket/Display.html?id=27615
659 - Imager would not load on Windows 98
660 http://rt.cpan.org/Ticket/Display.html?id=27653
662 Imager 0.59 - 14 June 2007

668 http://rt.cpan.org/Ticket/Display.html?id=27546
670 - cropping outside the image would return an Imager object with
671 no low-level image object, instead of returning false.

680 Imager 0.57_01 - 11 May 2007
683 - added to_rgb16 to produce a 16-bit/sample version of an image
685 - improve freetype 1.x text output efficiency
689 - search another place for rgb.txt, and check all the places
690 Imager::Color checks when deciding whether to skip testing it
691 http://rt.cpan.org/Ticket/Display.html?id=26064
693 - use a convolution kernel size based on the stddev rather than a
694 fixed size when performing a gaussian blur
695 http://rt.cpan.org/Ticket/Display.html?id=25645
697 - document the difference() method's mindist parameter, and debug it.
699 - put the Imager release number in the Inline::C generated code to
700 regenerate Inline code when a new release of Imager is installed.
701 http://rt.cpan.org/Ticket/Display.html?id=26278
703 - fix rendering on alpha channel images for the FreeType 1.x driver.

706 - fix rendering on alpha channel images for the T1lib driver.
707 http://rt.cpan.org/Ticket/Display.html?id=11972
709 - reworked library probing, we can now set more than one probe
710 function for a library. Disabled the default (non-freetype-config)
711 library probe and added an extra probe function that searches for
712 both ft2build.h and whatever it includes, and adds -I as needed.
713 Hopefully this will fix build problems like

717 Imager 0.57 - 30 Apr 2007
720 This is a maintenence release fixing a security issue in Imager.
722 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
723 overflow in malloced memory. There will be further discussion of
724 this issue in the ticket below.

726 CVE-2007-2459 CVE-2007-2413
727 The descriptions at cve.mitre.org varied in quality, please see the
728 ticket at rt.cpan.org for a more accurate description of the issue.
730 Imager 0.56 - 1 Apr 2007
733 - added support for reading 16-bit/sample PGM/PPM images
735 - added support for writing 16-bit/sample PGM/PPM images
737 - improved performance of reading PBM/PGM/PPM images
739 - added support for writing PBM images if the image is paletted and
740 contains only black and white
742 - added a new make_colors value - "mono"
744 - switched from the svn log Changes to a manual Changes to reduce
747 - new sample code - samples/flasher.pl
751 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
752 was returning an image object with an extra reference, this
753 resulted in a memory leak.
754 http://rt.cpan.org/Ticket/Display.html?id=24992
756 - fix rendering on alpha channel images for the FreeType 2.x driver
757 http://rt.cpan.org/Ticket/Display.html?id=11972
759 - reading bmp files now consitently handles short reads. You can now
760 supply a parameter to treat a short read as successful and set
762 http://rt.cpan.org/Ticket/Display.html?id=8426
764 - previously, reading ASCII PBM files required spaces between samples,
765 even though the format doesn't require that
767 - improved documentation of the unsharpmask filter (I hope)
768 http://rt.cpan.org/Ticket/Display.html?id=25531
770 - force flushing of the output from i_tt_dump_names() and test output
771 in t/t35ttfont.t to prevent output from being mixed up.
772 https://rt.cpan.org/Ticket/Display.html?id=24859
774 - rewrite a conditional expression as an if() to hopefully work around
775 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
776 https://rt.cpan.org/Ticket/Display.html?id=25561
778 - avoid Data::Dumper in regops.perl to support older releases of perl
779 https://rt.cpan.org/Ticket/Display.html?id=24391
781 Imager 0.55 - 16 Dec 2006
784 This is primarily a bug fix release.
786 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
788 There is one new feature:
790 - the Win32 font driver now supports UTF8 (RT 22166)
791 http://www.cpanforum.com/threads/3276
792 http://rt.cpan.org/Ticket/Display.html?id=22166
794 Several bugs were fixed:
796 - the string() method would not output the string "0"
797 http://rt.cpan.org/Public/Bug/Display.html?id=21770
799 - fills.c was failing to compile on Solaris 10 (compiler unknown)
800 http://rt.cpan.org/Public/Bug/Display.html?id=21944
802 - the gif_disposal and gif_user_input tags weren't being read from
804 http://rt.cpan.org/Public/Bug/Display.html?id=22192
806 - gif.c was failing to build under MSVC
807 http://rt.cpan.org/Ticket/Display.html?id=23922
809 - in some cases strings passed to the string() method were treated as
810 terminated by NUL (chr 0)
811 http://rt.cpan.org/Public/Bug/Display.html?id=21770
813 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
814 that's the default build name for zlib on Win32.
815 http://rt.cpan.org/Ticket/Display.html?id=23064
817 - search $Config{incpath} for headers too, which we should have been
820 Win32 font driver fixes:
822 - the global descent value from bounding box was the wrong sign
823 http://www.cpanforum.com/threads/3276
825 - if the first or last glyph overflowed the left or right side of the
826 advance width they would be clipped
829 Imager 0.54 - 14 Sep 2006
832 This is primarily a feature release:
834 - a new qtype value 'mixing' has been added to the scale()
835 method. This is faster than 'normal', slower than 'preview'. This
836 is based on the method used by pnmscale, and seems to produce less
837 blurry results than normal.
838 http://rt.cpan.org/Public/Bug/Display.html?id=20677
840 - the rubthrough() method can now render onto images with an alpha
842 http://rt.cpan.org/Ticket/Display.html?id=20678
844 - the read_multi() method now falls back to calling doing a single
845 image read via the read() method and write_multi() will now fall
846 back to calling write() if a single image is supplied. This means
847 you can simply call the read_multi() or write_multi() functions
848 without having to check if the type is formatted by that method.
849 http://rt.cpan.org/Ticket/Display.html?id=19457
850 http://rt.cpan.org/Ticket/Display.html?id=19458
852 - the GIF loop extension can now be written. If you don't have
853 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
855 http://rt.cpan.org/Ticket/Display.html?id=21185
857 - getscanline() and setscanline() can now read/write palette index
858 based data from/to the image for paletted images, by setting type to
860 http://rt.cpan.org/Ticket/Display.html?id=20338
862 - we no longer hassle you to disable GIF support
863 http://rt.cpan.org/Ticket/Display.html?id=20687
865 - minor documentation fixes
868 Imager 0.53 - 26 Jul 2006
871 This is a bugfix release.
873 Some test code was left in a code path not covered by the test
874 suite. A test was added to cover this code path and the test code was
876 http://rt.cpan.org/Public/Bug/Display.html?id=20705
879 Imager 0.52 - 25 Jul 2006
882 This is primarily a feature release, but contains a fair few bug
885 - ability to read and write MS Windows ICO and CUR files
887 - you can now add file format plugins to support new file formats
889 - add POD coverage tests
891 - setcolors() and addcolors() now accept color names and so on
892 instead of requiring Imager::Color objects.
893 http://rt.cpan.org/Ticket/Display.html?id=20056
895 - flood_fill() can now fill to a specified border color instead of
896 just to the area the same color as the seed.
897 http://rt.cpan.org/Ticket/Display.html?id=19618
902 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
903 calculating the advance width.
904 http://rt.cpan.org/Public/Bug/Display.html?id=20554
906 - bounding_box for the T1 driver wasn't including leading and
907 trailing spaces in the bounding box as the other drivers did, it also
908 produced strange results for empty strings or strings containing only
911 - when reading CMYK jpeg images they were being transferred to the
912 image object as is, producing a four channel image. It only looked ok
913 due to an old still unfixed Photoshop bug. We now convert from the
914 inverted CMYK that photoshop (and Corel for example) produce into RGB.
915 http://rt.cpan.org/Ticket/Display.html?id=20416
917 - reading a CYMK TIFF would result in a 4 channel image, reading any
918 image with more than 4 channels (eg. RGB with 2 alpha channels) would
920 http://rt.cpan.org/Ticket/Display.html?id=20415
922 - added /usr/local/include to the default include search path, since
923 we were already searching /usr/local/lib for libraries.
925 And various minor fixes and documentation updates.
928 Imager 0.51 - 23 Apr 2006
931 - fix a validation bug when processing JPEG EXIF data that can cause
933 http://rt.cpan.org/Public/Bug/Display.html?id=18496
935 - fix mis-processing of the src_maxx and src_maxy parameters of the
937 http://rt.cpan.org/Public/Bug/Display.html?id=18712
939 - fix a problem in Imager's "smart" handling of the color parameter
941 http://rt.cpan.org/Public/Bug/Display.html?id=18561
944 Imager 0.50 - 29 Mar 2006
947 - CRITICAL: fixes a segmentation fault from attempting to write a 2
948 or 4 channel image to jpeg or a 2 channel image to tga where the
949 output is an in-memeory buffer.
950 http://rt.cpan.org/Public/Bug/Display.html?id=18397
952 - fixes an incorrect pointer parameter in the PNG code
953 http://rt.cpan.org/Public/Bug/Display.html?id=18051
955 - skip Inline::C tests when building in a directory with spaces
