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 the GIF file handling code into a sub-module in preparation
12 for separate distribution.
13 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
17 - Imager::Probe was calling ExtUtils::Liblist to initialize
18 LD_RUN_PATH supplying an undefined value rather than the found
19 directory. Thanks to Justin Davis.
20 https://rt.cpan.org/Ticket/Display.html?id=60491
22 - only prepend ./ to font filenames when passing them to T1Lib and
23 then only when it would use its search mechanisms.
24 https://rt.cpan.org/Ticket/Display.html?id=60509
27 Imager 0.77 - 11 Aug 2010
30 I don't want Imager::File::PNG indexed as part of Imager, but forgot
31 to update the META.yml before updating the version.
33 - don't index Imager::File::PNG as part of Imager
35 - add resources to META.yml
37 Imager 0.76 - not released
42 - the align_string() method would ignore a string of "0" due to a
44 Thanks to Maurice Height for reporting this.
45 https://rt.cpan.org/Ticket/Display.html?id=60199
47 Imager 0.75_03 - 09 Aug 2010
52 - read_types() and write_types() would include png when it wasn't
53 available due to a problem with the %formats tie
55 - handle dependent libraries correctly (eg -lpng requiring -lz) in
56 the code run phase of library probing.
58 Imager 0.75_02 - 07 Aug 2010
63 - add file missing from MANIFEST, which was causing TIFF failures.
65 Imager 0.75_01 - 06 Aug 2010
68 Test release for the new PNG probe.
70 - added the ability to read multiple-image PNM files.
71 Note that unlike the pbm/pgm/ppm specification this accepts mixed
72 format files and allows white space padding between files.
73 Thanks to Philip Gwyn (Leolo) for this patch.
75 - moved the PNG file handling code into a sub-module in preparation
76 for separate distribution.
77 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
78 Also helps avoid complications from -I/-L compile/link options from
83 - Imager->new(data => $data) didn't try to process image file data in
85 https://rt.cpan.org/Ticket/Display.html?id=58761
87 - t/t50basicoo.t no longer depends on the other tests to generate its
89 https://rt.cpan.org/Ticket/Display.html?id=9798
90 Also, it wasn't testing pnm (pnm vs ppm mix-up)
92 - update the documentation of hardinvert to match the change in 0.62.
93 https://rt.cpan.org/Ticket/Display.html?id=59785
95 - added hardinvertall filter which also inverts the alpha channel
98 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
99 the probe can find the library for the test run.
100 https://rt.cpan.org/Ticket/Display.html?id=57518
102 Imager 0.75 - 20 Jun 2010
105 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
110 - an opacity fill based on a fountain fill would segfault when
111 filling an 8-bit/sample image.
113 - merge thickline branch polygon fix
114 https://rt.cpan.org/Ticket/Display.html?id=43518
116 Imager 0.74 - 7 May 2010
121 - read_multi() didn't handle a missing file format library correctly,
122 aborting on failing to call i_readgif_multi_wiol() or
123 i_readtiff_multi_wiol().
125 - fix spelling errors patched by Debian
126 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
128 - add an (unshipped) author test to spellcheck Imager's POD.
130 - update the TIFF file format documentation
131 https://rt.cpan.org/Ticket/Display.html?id=56510
133 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
135 Imager 0.73 - 15 Mar 2010
138 - implement outline circles, both anti-aliased and not
139 https://rt.cpan.org/Ticket/Display.html?id=19755
141 - a combine => "none" fill to a 1 or 3 channel image would produce
142 the incorrect colour.
144 Imager 0.72 - 09 Dec 2009
147 Bump version for release, since 0.71_03 is stable with CPAN testers.
149 Imager 0.71_03 - 5 Dec 2009
152 - further adjust the threads test so it only performs the tests on
153 perls where it's expected to work, and only if the threads module
156 Imager 0.71_02 - 1 Dec 2009
159 - adjust the way we load the threads module for the threads test so
160 it works with non-threaded perls
162 Imager 0.71_01 - 30 Nov 2009
167 - use scanline oriented operations to flip images instead of pixel
169 https://rt.cpan.org/Ticket/Display.html?id=39278
171 - use double/sample operations to flip large sample images instead of
172 8-bit sample operations.
173 https://rt.cpan.org/Ticket/Display.html?id=39280
176 https://rt.cpan.org/Ticket/Display.html?id=51874
178 - prevent double-frees when someone creates Imager objects and then
179 creates a thread. Note: this just handles some simple cases,
180 Imager doesn't support perl threads, and isn't likely to.
181 https://rt.cpan.org/Ticket/Display.html?id=52268
183 Imager 0.71 - 16 Nov 2009
186 - add the opacity fill type - an adaptor that modifies the opacity of
191 - the conv filter now enforces that the sum of the coefficients is
192 non-zero. Also, rather than skipping pixels off the edge off the
193 edge of the image, the closest edge pixel is used. Previously
194 dividing by the zero sum of coefficients could cause invalid
195 results or runtime exceptions.
196 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
199 Imager 0.70 - 21 Sep 2009
204 - release image row and comments memory on all error returns in gif
207 - handle zero length extensions, previously this would cause a null
209 Thanks to Krzysztof WojtaÅ for the test data and fix for this.
211 - an integer division meant that preview scaling to below 1 pixel
212 wide or high (which isn't too useful anyway) was calculating using
213 NaNs on most platforms, and causing an exception on others.
214 Thanks to David Cantrell for producing a backtrace of the crash on
215 his Alpha-NetBSD CPAN test box which made it possible to track this
218 Imager 0.69 - 08 Sep 2009
223 - broken test fix - was attempting to call a function skip_all, when
224 that should be a parameter to plan().
226 - briefly document apidocs.perl, the tool used to build
227 Imager::APIRef and make some minor enhancements
229 - various minor documentation enhancements and fixes.
231 Imager 0.68 - 07 Sep 2009
234 - Imager->new(file => $filename) and other similar incantations will
236 https://rt.cpan.org/Ticket/Display.html?id=48261
240 - avoid using CHECK as a label in Imager::Test
241 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
243 - re-work most image file test files that require a library into
244 separate library present/not present files to remove stupidly long
247 - don't treat rubthrough() outside the bounds of the target image as
249 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
251 Imager 0.67_01 - 02 Sep 2009
256 - correct documentation of default of raw image interleave read
258 https://rt.cpan.org/Ticket/Display.html?id=42074
260 - add raw_ prefix to raw read parameters, though the original names
263 - fail the read if an invalid raw_interleave parameter is supplied
265 - warn if no interleave or raw_interleave parameter is supplied,
266 since the documented default was wrong, and incompatible with the
269 - for reading raw images, if raw_storechannels > raw_datachannels,
270 set the extra channels in the image to 0
272 - when probing for executables like freetype-config, search for .bat
273 and .cmd on MSWin32, as well as .exe.
274 https://rt.cpan.org/Ticket/Display.html?id=49275
276 - re-work the external libraries section of README:
277 - list Debian and Redhat package names for each library
281 - use the new EU::MM META_MERGE facility instead of generating
282 META.yml from scratch
283 https://rt.cpan.org/Ticket/Display.html?id=47888
285 - use Devel::CheckLib (bundled, modified) to check which release of
286 libtiff is installed and reject 3.9.0
287 http://bugzilla.maptools.org/show_bug.cgi?id=2088
288 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
290 Imager 0.67 - 12 Dec 2008
295 - fix a packaging error
297 Imager 0.66 - 12 Dec 2008
300 - 24-bit color .ICO/.CUR files can now be read.
304 - an optimization skipping 0 src alpha values could cause the
305 rubthrough() to read past the end of a buffer.
306 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
308 - corrected a reference leak where writing GIFs would leak memory.
309 This could also happen calling to_paletted().
310 Also documented the underlying long existing feature where the
311 colors parameter is filled with the generated color table and added
313 http://rt.cpan.org/Ticket/Display.html?id=41028
315 - write out the image size in bytes field of a BMP correctly.
316 http://rt.cpan.org/Ticket/Display.html?id=41406
318 - add limited tests for Imager::ExtUtils
320 - make Imager::ExtUtils->includes use an absolute path, since
321 a relative path could cause failures using Inline::C.
322 http://rt.cpan.org/Ticket/Display.html?id=37353
324 - re-arrange the POD for Imager::Font::BBox:
325 - mark total_width(), pos_width(), end_offset() obsolete, since
326 they're mostly for backwards compatibility
327 - group width methods and height methods
328 https://rt.cpan.org/Ticket/Display.html?id=39999
330 Imager 0.65 - 20 May 2008
335 - In some cases when an error occurs reading those parts of a JPEG
336 file after the image the scan-line buffer could be freed a second
337 time. In cases where the the error occured while reading the image
338 data it's possible that the buffer could have leaked.
339 Thanks to Gabriel Vasseur for reporting this and help in tracking
342 - the gif_screen_height tag was overriding the screen width and being
343 ignored for the screen height when present.
344 https://rt.cpan.org/Public/Bug/Display.html?id=35568
346 Imager 0.64 - 23 April 2008
349 This is a bug fix release. This includes a fix for a possible
354 - Possible security issue: The floating point sample path for image
355 based fills had a buffer overflow. This would overwrite the end of
356 a malloc()ed buffer with double precision floats.
357 http://rt.cpan.org/Ticket/Display.html?id=35324
360 - check that the result of fileno($fh) is defined rather than simply
361 true when read() or write() is supplied with an fh parameter.
362 http://rt.cpan.org/Ticket/Display.html?id=35139
364 - i_scale_axis() wasn't checking the result of i_img_new_ch()
365 resulting in a SIGSEGV when attempting to scale an image to a size
366 too large to fit in memory. This is a NULL pointer access issue,
367 not a buffer overflow.
368 Added a check for the failure.
369 scale_calculate() (and hence scale()) will now fail if any of the
370 scale size parameters are a reference.
371 http://rt.cpan.org/Ticket/Display.html?id=35172
373 - Regression: filling a greyscale image with a hatch used the wrong
374 color channels from the supplied fg/bg colors.
375 https://rt.cpan.org/Ticket/Display.html?id=35278
377 - fixed a related problem for image fills.
379 Imager 0.63 - 7 April 2008
382 This release primarily contains changes to improve ease of use -
383 rather than you having to convert images to the appropriate number of
384 channels, Imager handles it internally. How to handle drawing colors
385 and the default combine mode is a thornier problem left for some other
388 - the font libraries are now only initialized when needed.
389 http://rt.cpan.org/Ticket/Display.html?id=28825
391 - moved the imtoc.perl code into Imager::Preprocess
393 - paste() and rubthrough() now adapt the source image data to the
394 destination, so you can now safely paste/rubthrough from greyscale
395 images to color images or back, or from alpha channel images to
396 noalpha channels or back.
397 https://rt.cpan.org/Ticket/Display.html?id=30908
399 - rubthrough() now falls back to pasting when the source doesn't have
400 an alpha channel. This effectively treats the source as having a
401 max alpha channel, the right thing to do.
402 http://rt.cpan.org/Ticket/Display.html?id=29944
404 - re-worked most of the area filling code to use a common set of
405 functions when filling.
406 Corrected normal combine mode.
407 Rewrote most of the combine modes to match the way the SVG draft
408 defines them with respect to a translucent source and destination.
409 Added tests for translucent source and destination.
410 Added tests to check 8-bit/sample and double/sample combines work
412 https://rt.cpan.org/Ticket/Display.html?id=29879
414 - writing a 2 or 4 channel image to a JPEG file will now write that
415 image as if composited against a background, black by default,
416 overridable with the i_background tag/parameter.
417 https://rt.cpan.org/Ticket/Display.html?id=29876
419 - writing a 2 or 4 channel image to a PGM/PPM file will now write
420 that image as if composited against a background, black by default,
421 overridable with the i_background tag/parameter.
422 http://rt.cpan.org/Ticket/Display.html?id=30074
424 - writing a 2 or 4 channel image to a BMP file will now write that
425 image as if composited against a background, black by default,
426 overridable with the i_background tag/parameter.
427 http://rt.cpan.org/Ticket/Display.html?id=30075
431 - Imager::Matrix2d->translate() now only requires one of the x or y
433 http://rt.cpan.org/Ticket/Display.html?id=29937
435 - mixing qtype scaling now sets all channels of a pixel to zero if
436 the pixel has zero coverage (zero alpha). This should produce more
437 compressible output files.
438 http://rt.cpan.org/Ticket/Display.html?id=32324
440 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
442 https://bugzilla.redhat.com/show_bug.cgi?id=166254
443 I'm not changing the #! lines of the sample code, since it's sample
444 code, not intended for installation.
445 http://rt.cpan.org/Ticket/Display.html?id=33408
447 - some TGA images weren't being detected correctly as TGA images
448 https://rt.cpan.org/Ticket/Display.html?id=32925
450 - handling of the left-over bit for 16-bit/pixel TGA images has been
451 changed to match the behaviour of the GIMP. Previously the bit
452 being set was treated as an opaque pixel, but one user reported a
453 problem with loading such an image. I haven't been able to find any
454 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
455 I'll match it's behaviour. See issue 114913 in the GIMP's
457 http://rt.cpan.org/Ticket/Display.html?id=32926
459 Imager 0.62 - 10 December 2007
462 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
463 to /path under your home directory.
464 http://rt.cpan.org/Ticket/Display.html?id=29484
466 - the old dynaload code used Mach API functions to load dynamic
467 libraries on Mac OS X. These APIs have been deprecated in OS X
468 10.5 and were causing some build problems.
469 So henceforth Imager uses the dlopen() family of functions, and you
470 will need version 10.3 or later of OS X.
472 - added the det() function to the transform2() engine.
473 added the sample quad_to_square.pl
474 Courtesy Richard Fairhurst.
475 http://rt.cpan.org/Ticket/Display.html?id=31244
479 - samples/gifscale.pl sourced the base value for gif_top from
481 Thanks to Eleneldil G. Arilou for pointing this out.
483 - t/t82inline.t no longer loads B at runtime, to work around a bug
484 in some 5.005_0[45] installations.
485 http://rt.cpan.org/Ticket/Display.html?id=30508
487 - work around Module::Depends::Intrusive bug #21229
488 http://rt.cpan.org/Ticket/Display.html?id=30520
490 - the hardinvert filter no-longer inverts the alpha channel.
491 http://rt.cpan.org/Ticket/Display.html?id=30002
493 - the hardinvert filter now supports large samples
495 Imager 0.61_02 - 28 November 2007
498 - major TIFF support re-work
499 http://rt.cpan.org/Ticket/Display.html?id=20329
501 - added a C level image interface for accessing samples from 1-32
502 bits, exposed this at the perl level in getsamples()
504 - the conv filter now works at floating point precision for high bit
507 - added is_bilevel method to test whether an image should be written as
508 a bilevel image if the image format supports it.
510 - added -log-stderr as an Imager import list option
512 - added some important types to Imager::APIRef
514 - added test_image_double() to Imager::Test
518 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
521 - the scale() method with qtype mixing now handles images with an
522 alpha channel correctly.
524 - fixed a broken link from the "animated GIF" entry in the concept index.
525 Thanks to Slaven Rezic.
526 http://rt.cpan.org/Ticket/Display.html?id=30889
528 - on some perl's the infix expression parser test would fail due to
529 actions in the grammar returning false. Made sure all actions return
531 Thanks to Richard Fairhurst for spending a lot of time in tracking
533 http://rt.cpan.org/Public/Bug/Display.html?id=29562
535 Imager 0.61 - 5 November 2007
538 - added samples/gifscale.pl, which adjusts the screen size/position tags
539 when scaling an animated gif
540 http://rt.cpan.org/Ticket/Display.html?id=27591
544 - correct handling of sz in matrix_transform() - this should allow
545 perspective type transformations to work now.
546 http://rt.cpan.org/Ticket/Display.html?id=29936
548 - prevent a cast to integer warning on x64 builds in datatypes.c
549 also fixed some other type warnings
550 https://rt.cpan.org/Ticket/Display.html?id=30204
552 - some sub-directory tests depended on files produced by the parent
554 http://rt.cpan.org/Ticket/Display.html?id=30203
556 - Imager::Font::Wrap doesn't correctly set savepos
557 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
558 http://rt.cpan.org/Ticket/Display.html?id=29771
560 - test 171 in t/t01introvert.t was failing on perls configured to
562 http://rt.cpan.org/Ticket/Display.html?id=29413
564 - the code for the transform2() uminus operator was missing a break.
565 Added tests for better code coverage of the ops.
566 http://rt.cpan.org/Ticket/Display.html?id=29296
568 - the SGI RLE compression code could overflow its compression buffer
569 http://rt.cpan.org/Ticket/Display.html?id=30334
571 - the 32-bit output function used by the SGI code only handled values
572 under 0x10000. This was most noticable when writing large RLE images.
573 http://rt.cpan.org/Ticket/Display.html?id=30335
575 - validate chan_count for chans == NULL for each of the i_gsamp()
577 http://rt.cpan.org/Ticket/Display.html?id=28985
579 - attempt to work around the test failure at
580 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
581 http://rt.cpan.org/Ticket/Display.html?id=29562
583 - improve the error messages produced when attempting to read or write
584 an unknown image file format.
585 http://rt.cpan.org/Ticket/Display.html?id=30103
587 - improve the transform2() documentation
588 http://rt.cpan.org/Ticket/Display.html?id=29267
590 - correctly generate the author key in META.yml
591 http://rt.cpan.org/Ticket/Display.html?id=30377
593 - correctly blend a rotated (or matrix_transformed()) image when
594 performing interpolation in the presence of an alpha channel.
595 Also corrected the centring of the rotated image on the output
598 Imager 0.60 - 30 August 2007
601 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
602 now has full SGI RGB image format, including RLE and 16-bit/sample
604 https://rt.cpan.org/Ticket/Display.html?id=8666
606 - logging functions are now available in the API
608 - applied Gabriel Vasseur's patch
609 added documentation, further tests, and support for greyscale images
610 Obviously problems are my fault :)
611 https://rt.cpan.org/Ticket/Display.html?id=28142
613 - the mask for ICO/CUR images is now applied as an alpha channel to
614 the returned image. For the old behaviour, supply ico_masked => 0
615 to read() or read_multi(). This should be less confusing when
616 using Imager as a general image processor.
617 https://rt.cpan.org/Ticket/Display.html?id=29001
621 - in some cases it's possible for giflib/libungif to return color
622 indexes outside the range of colors defined by the image's palette.
623 We now expand the palette to match the indexes used.
624 Thanks to Gabriel Vasseur for reporting this.
626 - fixed various memory leaks that could occur when failing to read png,
627 jpeg, bmp or tga files.
629 - to avoid confusion, channels not present in the image are returned as
630 zero by getscanline(). This has no effect on the C level i_glin()
631 and i_glinf() API functions which continue to not set the unused
634 - the convert() method now returns an image of the same sample size as
636 https://rt.cpan.org/Ticket/Display.html?id=28492
638 - remove repeated text in Imager::Files
639 http://rt.cpan.org/Ticket/Display.html?id=27589
641 - be even more explicit that scale() and friends don't modify the source
642 image, but return a new image.
643 http://rt.cpan.org/Ticket/Display.html?id=28570
645 - improve the error message from errstr() when you try to load a font
646 for which the driver hasn't been built in Imager.
647 http://rt.cpan.org/Ticket/Display.html?id=27571
649 - transparency is now enabled by default when writing GIF images
650 http://rt.cpan.org/Ticket/Display.html?id=27615
652 - Imager would not load on Windows 98
653 http://rt.cpan.org/Ticket/Display.html?id=27653
655 Imager 0.59 - 14 June 2007
660 - fixes a regression introduced by the fixes for RT 11972
661 http://rt.cpan.org/Ticket/Display.html?id=27546
663 - cropping outside the image would return an Imager object with
664 no low-level image object, instead of returning false.
665 Fixed by: Philip Gwyn (Leolo)
666 http://rt.cpan.org/Ticket/Display.html?id=27509
668 Imager 0.58 - 16 May 2007
671 No significant changes from 0.57_01.
673 Imager 0.57_01 - 11 May 2007
676 - added to_rgb16 to produce a 16-bit/sample version of an image
678 - improve freetype 1.x text output efficiency
682 - search another place for rgb.txt, and check all the places
683 Imager::Color checks when deciding whether to skip testing it
684 http://rt.cpan.org/Ticket/Display.html?id=26064
686 - use a convolution kernel size based on the stddev rather than a
687 fixed size when performing a gaussian blur
688 http://rt.cpan.org/Ticket/Display.html?id=25645
690 - document the difference() method's mindist parameter, and debug it.
692 - put the Imager release number in the Inline::C generated code to
693 regenerate Inline code when a new release of Imager is installed.
694 http://rt.cpan.org/Ticket/Display.html?id=26278
696 - fix rendering on alpha channel images for the FreeType 1.x driver.

700 http://rt.cpan.org/Ticket/Display.html?id=11972
702 - reworked library probing, we can now set more than one probe
703 function for a library. Disabled the default (non-freetype-config)
704 library probe and added an extra probe function that searches for
705 both ft2build.h and whatever it includes, and adds -I as needed.
706 Hopefully this will fix build problems like

710 Imager 0.57 - 30 Apr 2007
713 This is a maintenence release fixing a security issue in Imager.
715 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
716 overflow in malloced memory. There will be further discussion of
717 this issue in the ticket below.
718 http://rt.cpan.org/Ticket/Display.html?id=26811
719 CVE-2007-2459 CVE-2007-2413
720 The descriptions at cve.mitre.org varied in quality, please see the
721 ticket at rt.cpan.org for a more accurate description of the issue.
723 Imager 0.56 - 1 Apr 2007
726 - added support for reading 16-bit/sample PGM/PPM images
728 - added support for writing 16-bit/sample PGM/PPM images
730 - improved performance of reading PBM/PGM/PPM images
732 - added support for writing PBM images if the image is paletted and
733 contains only black and white
735 - added a new make_colors value - "mono"
737 - switched from the svn log Changes to a manual Changes to reduce
740 - new sample code - samples/flasher.pl
744 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
745 was returning an image object with an extra reference, this
746 resulted in a memory leak.
747 http://rt.cpan.org/Ticket/Display.html?id=24992
749 - fix rendering on alpha channel images for the FreeType 2.x driver
750 http://rt.cpan.org/Ticket/Display.html?id=11972
752 - reading bmp files now consitently handles short reads. You can now
753 supply a parameter to treat a short read as successful and set
755 http://rt.cpan.org/Ticket/Display.html?id=8426
757 - previously, reading ASCII PBM files required spaces between samples,
758 even though the format doesn't require that
760 - improved documentation of the unsharpmask filter (I hope)
761 http://rt.cpan.org/Ticket/Display.html?id=25531
763 - force flushing of the output from i_tt_dump_names() and test output
764 in t/t35ttfont.t to prevent output from being mixed up.
765 https://rt.cpan.org/Ticket/Display.html?id=24859
767 - rewrite a conditional expression as an if() to hopefully work around
768 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
769 https://rt.cpan.org/Ticket/Display.html?id=25561
771 - avoid Data::Dumper in regops.perl to support older releases of perl
772 https://rt.cpan.org/Ticket/Display.html?id=24391
774 Imager 0.55 - 16 Dec 2006
777 This is primarily a bug fix release.
779 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
781 There is one new feature:
783 - the Win32 font driver now supports UTF8 (RT 22166)
784 http://www.cpanforum.com/threads/3276
785 http://rt.cpan.org/Ticket/Display.html?id=22166
787 Several bugs were fixed:
789 - the string() method would not output the string "0"
790 http://rt.cpan.org/Public/Bug/Display.html?id=21770
792 - fills.c was failing to compile on Solaris 10 (compiler unknown)
793 http://rt.cpan.org/Public/Bug/Display.html?id=21944
795 - the gif_disposal and gif_user_input tags weren't being read from
797 http://rt.cpan.org/Public/Bug/Display.html?id=22192
799 - gif.c was failing to build under MSVC
800 http://rt.cpan.org/Ticket/Display.html?id=23922
802 - in some cases strings passed to the string() method were treated as
803 terminated by NUL (chr 0)
804 http://rt.cpan.org/Public/Bug/Display.html?id=21770
806 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
807 that's the default build name for zlib on Win32.
808 http://rt.cpan.org/Ticket/Display.html?id=23064
810 - search $Config{incpath} for headers too, which we should have been
813 Win32 font driver fixes:
815 - the global descent value from bounding box was the wrong sign
816 http://www.cpanforum.com/threads/3276
818 - if the first or last glyph overflowed the left or right side of the
819 advance width they would be clipped
822 Imager 0.54 - 14 Sep 2006
825 This is primarily a feature release:
827 - a new qtype value 'mixing' has been added to the scale()
828 method. This is faster than 'normal', slower than 'preview'. This
829 is based on the method used by pnmscale, and seems to produce less
830 blurry results than normal.
831 http://rt.cpan.org/Public/Bug/Display.html?id=20677
833 - the rubthrough() method can now render onto images with an alpha
835 http://rt.cpan.org/Ticket/Display.html?id=20678
837 - the read_multi() method now falls back to calling doing a single
838 image read via the read() method and write_multi() will now fall
839 back to calling write() if a single image is supplied. This means
840 you can simply call the read_multi() or write_multi() functions
841 without having to check if the type is formatted by that method.
842 http://rt.cpan.org/Ticket/Display.html?id=19457
843 http://rt.cpan.org/Ticket/Display.html?id=19458
845 - the GIF loop extension can now be written. If you don't have
846 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
848 http://rt.cpan.org/Ticket/Display.html?id=21185
850 - getscanline() and setscanline() can now read/write palette index
851 based data from/to the image for paletted images, by setting type to
853 http://rt.cpan.org/Ticket/Display.html?id=20338
855 - we no longer hassle you to disable GIF support
856 http://rt.cpan.org/Ticket/Display.html?id=20687
858 - minor documentation fixes
861 Imager 0.53 - 26 Jul 2006
864 This is a bugfix release.
866 Some test code was left in a code path not covered by the test
867 suite. A test was added to cover this code path and the test code was
869 http://rt.cpan.org/Public/Bug/Display.html?id=20705
872 Imager 0.52 - 25 Jul 2006
875 This is primarily a feature release, but contains a fair few bug
878 - ability to read and write MS Windows ICO and CUR files
880 - you can now add file format plugins to support new file formats
882 - add POD coverage tests
884 - setcolors() and addcolors() now accept color names and so on
885 instead of requiring Imager::Color objects.
886 http://rt.cpan.org/Ticket/Display.html?id=20056
888 - flood_fill() can now fill to a specified border color instead of
889 just to the area the same color as the seed.
890 http://rt.cpan.org/Ticket/Display.html?id=19618
895 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
896 calculating the advance width.
897 http://rt.cpan.org/Public/Bug/Display.html?id=20554
899 - bounding_box for the T1 driver wasn't including leading and
900 trailing spaces in the bounding box as the other drivers did, it also
901 produced strange results for empty strings or strings containing only
904 - when reading CMYK jpeg images they were being transferred to the
905 image object as is, producing a four channel image. It only looked ok
906 due to an old still unfixed Photoshop bug. We now convert from the
907 inverted CMYK that photoshop (and Corel for example) produce into RGB.
908 http://rt.cpan.org/Ticket/Display.html?id=20416
910 - reading a CYMK TIFF would result in a 4 channel image, reading any
911 image with more than 4 channels (eg. RGB with 2 alpha channels) would
913 http://rt.cpan.org/Ticket/Display.html?id=20415
915 - added /usr/local/include to the default include search path, since
916 we were already searching /usr/local/lib for libraries.
918 And various minor fixes and documentation updates.
921 Imager 0.51 - 23 Apr 2006
924 - fix a validation bug when processing JPEG EXIF data that can cause
926 http://rt.cpan.org/Public/Bug/Display.html?id=18496
928 - fix mis-processing of the src_maxx and src_maxy parameters of the
930 http://rt.cpan.org/Public/Bug/Display.html?id=18712
932 - fix a problem in Imager's "smart" handling of the color parameter
934 http://rt.cpan.org/Public/Bug/Display.html?id=18561
937 Imager 0.50 - 29 Mar 2006
940 - CRITICAL: fixes a segmentation fault from attempting to write a 2
941 or 4 channel image to jpeg or a 2 channel image to tga where the
942 output is an in-memeory buffer.
943 http://rt.cpan.org/Public/Bug/Display.html?id=18397
945 - fixes an incorrect pointer parameter in the PNG code
946 http://rt.cpan.org/Public/Bug/Display.html?id=18051
948 - skip Inline::C tests when building in a directory with spaces
949 http://rt.cpan.org/Public/Bug/Display.html?id=18049
