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 Imager 0.77 - 11 Aug 2010
25 I don't want Imager::File::PNG indexed as part of Imager, but forgot
26 to update the META.yml before updating the version.
28 - don't index Imager::File::PNG as part of Imager
30 - add resources to META.yml
32 Imager 0.76 - not released
37 - the align_string() method would ignore a string of "0" due to a
39 Thanks to Maurice Height for reporting this.
40 https://rt.cpan.org/Ticket/Display.html?id=60199
42 Imager 0.75_03 - 09 Aug 2010
47 - read_types() and write_types() would include png when it wasn't
48 available due to a problem with the %formats tie
50 - handle dependent libraries correctly (eg -lpng requiring -lz) in
51 the code run phase of library probing.
53 Imager 0.75_02 - 07 Aug 2010
58 - add file missing from MANIFEST, which was causing TIFF failures.
60 Imager 0.75_01 - 06 Aug 2010
63 Test release for the new PNG probe.
65 - added the ability to read multiple-image PNM files.
66 Note that unlike the pbm/pgm/ppm specification this accepts mixed
67 format files and allows white space padding between files.
68 Thanks to Philip Gwyn (Leolo) for this patch.
70 - moved the PNG file handling code into a sub-module in preparation
71 for separate distribution.
72 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
73 Also helps avoid complications from -I/-L compile/link options from
78 - Imager->new(data => $data) didn't try to process image file data in
80 https://rt.cpan.org/Ticket/Display.html?id=58761
82 - t/t50basicoo.t no longer depends on the other tests to generate its
84 https://rt.cpan.org/Ticket/Display.html?id=9798
85 Also, it wasn't testing pnm (pnm vs ppm mix-up)
87 - update the documentation of hardinvert to match the change in 0.62.
88 https://rt.cpan.org/Ticket/Display.html?id=59785
90 - added hardinvertall filter which also inverts the alpha channel
93 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
94 the probe can find the library for the test run.
95 https://rt.cpan.org/Ticket/Display.html?id=57518
97 Imager 0.75 - 20 Jun 2010
100 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
105 - an opacity fill based on a fountain fill would segfault when
106 filling an 8-bit/sample image.
108 - merge thickline branch polygon fix
109 https://rt.cpan.org/Ticket/Display.html?id=43518
111 Imager 0.74 - 7 May 2010
116 - read_multi() didn't handle a missing file format library correctly,
117 aborting on failing to call i_readgif_multi_wiol() or
118 i_readtiff_multi_wiol().
120 - fix spelling errors patched by Debian
121 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
123 - add an (unshipped) author test to spellcheck Imager's POD.
125 - update the TIFF file format documentation
126 https://rt.cpan.org/Ticket/Display.html?id=56510
128 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
130 Imager 0.73 - 15 Mar 2010
133 - implement outline circles, both anti-aliased and not
134 https://rt.cpan.org/Ticket/Display.html?id=19755
136 - a combine => "none" fill to a 1 or 3 channel image would produce
137 the incorrect colour.
139 Imager 0.72 - 09 Dec 2009
142 Bump version for release, since 0.71_03 is stable with CPAN testers.
144 Imager 0.71_03 - 5 Dec 2009
147 - further adjust the threads test so it only performs the tests on
148 perls where it's expected to work, and only if the threads module
151 Imager 0.71_02 - 1 Dec 2009
154 - adjust the way we load the threads module for the threads test so
155 it works with non-threaded perls
157 Imager 0.71_01 - 30 Nov 2009
162 - use scanline oriented operations to flip images instead of pixel
164 https://rt.cpan.org/Ticket/Display.html?id=39278
166 - use double/sample operations to flip large sample images instead of
167 8-bit sample operations.
168 https://rt.cpan.org/Ticket/Display.html?id=39280
171 https://rt.cpan.org/Ticket/Display.html?id=51874
173 - prevent double-frees when someone creates Imager objects and then
174 creates a thread. Note: this just handles some simple cases,
175 Imager doesn't support perl threads, and isn't likely to.
176 https://rt.cpan.org/Ticket/Display.html?id=52268
178 Imager 0.71 - 16 Nov 2009
181 - add the opacity fill type - an adaptor that modifies the opacity of
186 - the conv filter now enforces that the sum of the coefficients is
187 non-zero. Also, rather than skipping pixels off the edge off the
188 edge of the image, the closest edge pixel is used. Previously
189 dividing by the zero sum of coefficients could cause invalid
190 results or runtime exceptions.
191 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
194 Imager 0.70 - 21 Sep 2009
199 - release image row and comments memory on all error returns in gif
202 - handle zero length extensions, previously this would cause a null
204 Thanks to Krzysztof WojtaÅ for the test data and fix for this.
206 - an integer division meant that preview scaling to below 1 pixel
207 wide or high (which isn't too useful anyway) was calculating using
208 NaNs on most platforms, and causing an exception on others.
209 Thanks to David Cantrell for producing a backtrace of the crash on
210 his Alpha-NetBSD CPAN test box which made it possible to track this
213 Imager 0.69 - 08 Sep 2009
218 - broken test fix - was attempting to call a function skip_all, when
219 that should be a parameter to plan().
221 - briefly document apidocs.perl, the tool used to build
222 Imager::APIRef and make some minor enhancements
224 - various minor documentation enhancements and fixes.
226 Imager 0.68 - 07 Sep 2009
229 - Imager->new(file => $filename) and other similar incantations will
231 https://rt.cpan.org/Ticket/Display.html?id=48261
235 - avoid using CHECK as a label in Imager::Test
236 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
238 - re-work most image file test files that require a library into
239 separate library present/not present files to remove stupidly long
242 - don't treat rubthrough() outside the bounds of the target image as
244 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
246 Imager 0.67_01 - 02 Sep 2009
251 - correct documentation of default of raw image interleave read
253 https://rt.cpan.org/Ticket/Display.html?id=42074
255 - add raw_ prefix to raw read parameters, though the original names
258 - fail the read if an invalid raw_interleave parameter is supplied
260 - warn if no interleave or raw_interleave parameter is supplied,
261 since the documented default was wrong, and incompatible with the
264 - for reading raw images, if raw_storechannels > raw_datachannels,
265 set the extra channels in the image to 0
267 - when probing for executables like freetype-config, search for .bat
268 and .cmd on MSWin32, as well as .exe.
269 https://rt.cpan.org/Ticket/Display.html?id=49275
271 - re-work the external libraries section of README:
272 - list Debian and Redhat package names for each library
276 - use the new EU::MM META_MERGE facility instead of generating
277 META.yml from scratch
278 https://rt.cpan.org/Ticket/Display.html?id=47888
280 - use Devel::CheckLib (bundled, modified) to check which release of
281 libtiff is installed and reject 3.9.0
282 http://bugzilla.maptools.org/show_bug.cgi?id=2088
283 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
285 Imager 0.67 - 12 Dec 2008
290 - fix a packaging error
292 Imager 0.66 - 12 Dec 2008
295 - 24-bit color .ICO/.CUR files can now be read.
299 - an optimization skipping 0 src alpha values could cause the
300 rubthrough() to read past the end of a buffer.
301 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
303 - corrected a reference leak where writing GIFs would leak memory.
304 This could also happen calling to_paletted().
305 Also documented the underlying long existing feature where the
306 colors parameter is filled with the generated color table and added
308 http://rt.cpan.org/Ticket/Display.html?id=41028
310 - write out the image size in bytes field of a BMP correctly.
311 http://rt.cpan.org/Ticket/Display.html?id=41406
313 - add limited tests for Imager::ExtUtils
315 - make Imager::ExtUtils->includes use an absolute path, since
316 a relative path could cause failures using Inline::C.
317 http://rt.cpan.org/Ticket/Display.html?id=37353
319 - re-arrange the POD for Imager::Font::BBox:
320 - mark total_width(), pos_width(), end_offset() obsolete, since
321 they're mostly for backwards compatibility
322 - group width methods and height methods
323 https://rt.cpan.org/Ticket/Display.html?id=39999
325 Imager 0.65 - 20 May 2008
330 - In some cases when an error occurs reading those parts of a JPEG
331 file after the image the scan-line buffer could be freed a second
332 time. In cases where the the error occured while reading the image
333 data it's possible that the buffer could have leaked.
334 Thanks to Gabriel Vasseur for reporting this and help in tracking
337 - the gif_screen_height tag was overriding the screen width and being
338 ignored for the screen height when present.
339 https://rt.cpan.org/Public/Bug/Display.html?id=35568
341 Imager 0.64 - 23 April 2008
344 This is a bug fix release. This includes a fix for a possible
349 - Possible security issue: The floating point sample path for image
350 based fills had a buffer overflow. This would overwrite the end of
351 a malloc()ed buffer with double precision floats.
352 http://rt.cpan.org/Ticket/Display.html?id=35324
355 - check that the result of fileno($fh) is defined rather than simply
356 true when read() or write() is supplied with an fh parameter.
357 http://rt.cpan.org/Ticket/Display.html?id=35139
359 - i_scale_axis() wasn't checking the result of i_img_new_ch()
360 resulting in a SIGSEGV when attempting to scale an image to a size
361 too large to fit in memory. This is a NULL pointer access issue,
362 not a buffer overflow.
363 Added a check for the failure.
364 scale_calculate() (and hence scale()) will now fail if any of the
365 scale size parameters are a reference.
366 http://rt.cpan.org/Ticket/Display.html?id=35172
368 - Regression: filling a greyscale image with a hatch used the wrong
369 color channels from the supplied fg/bg colors.
370 https://rt.cpan.org/Ticket/Display.html?id=35278
372 - fixed a related problem for image fills.
374 Imager 0.63 - 7 April 2008
377 This release primarily contains changes to improve ease of use -
378 rather than you having to convert images to the appropriate number of
379 channels, Imager handles it internally. How to handle drawing colors
380 and the default combine mode is a thornier problem left for some other
383 - the font libraries are now only initialized when needed.
384 http://rt.cpan.org/Ticket/Display.html?id=28825
386 - moved the imtoc.perl code into Imager::Preprocess
388 - paste() and rubthrough() now adapt the source image data to the
389 destination, so you can now safely paste/rubthrough from greyscale
390 images to color images or back, or from alpha channel images to
391 noalpha channels or back.
392 https://rt.cpan.org/Ticket/Display.html?id=30908
394 - rubthrough() now falls back to pasting when the source doesn't have
395 an alpha channel. This effectively treats the source as having a
396 max alpha channel, the right thing to do.
397 http://rt.cpan.org/Ticket/Display.html?id=29944
399 - re-worked most of the area filling code to use a common set of
400 functions when filling.
401 Corrected normal combine mode.
402 Rewrote most of the combine modes to match the way the SVG draft
403 defines them with respect to a translucent source and destination.
404 Added tests for translucent source and destination.
405 Added tests to check 8-bit/sample and double/sample combines work
407 https://rt.cpan.org/Ticket/Display.html?id=29879
409 - writing a 2 or 4 channel image to a JPEG file will now write that
410 image as if composited against a background, black by default,
411 overridable with the i_background tag/parameter.
412 https://rt.cpan.org/Ticket/Display.html?id=29876
414 - writing a 2 or 4 channel image to a PGM/PPM file will now write
415 that image as if composited against a background, black by default,
416 overridable with the i_background tag/parameter.
417 http://rt.cpan.org/Ticket/Display.html?id=30074
419 - writing a 2 or 4 channel image to a BMP file will now write that
420 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=30075
426 - Imager::Matrix2d->translate() now only requires one of the x or y
428 http://rt.cpan.org/Ticket/Display.html?id=29937
430 - mixing qtype scaling now sets all channels of a pixel to zero if
431 the pixel has zero coverage (zero alpha). This should produce more
432 compressible output files.
433 http://rt.cpan.org/Ticket/Display.html?id=32324
435 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
437 https://bugzilla.redhat.com/show_bug.cgi?id=166254
438 I'm not changing the #! lines of the sample code, since it's sample
439 code, not intended for installation.
440 http://rt.cpan.org/Ticket/Display.html?id=33408
442 - some TGA images weren't being detected correctly as TGA images
443 https://rt.cpan.org/Ticket/Display.html?id=32925
445 - handling of the left-over bit for 16-bit/pixel TGA images has been
446 changed to match the behaviour of the GIMP. Previously the bit
447 being set was treated as an opaque pixel, but one user reported a
448 problem with loading such an image. I haven't been able to find any
449 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
450 I'll match it's behaviour. See issue 114913 in the GIMP's
452 http://rt.cpan.org/Ticket/Display.html?id=32926
454 Imager 0.62 - 10 December 2007
457 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
458 to /path under your home directory.
459 http://rt.cpan.org/Ticket/Display.html?id=29484
461 - the old dynaload code used Mach API functions to load dynamic
462 libraries on Mac OS X. These APIs have been deprecated in OS X
463 10.5 and were causing some build problems.
464 So henceforth Imager uses the dlopen() family of functions, and you
465 will need version 10.3 or later of OS X.
467 - added the det() function to the transform2() engine.
468 added the sample quad_to_square.pl
469 Courtesy Richard Fairhurst.
470 http://rt.cpan.org/Ticket/Display.html?id=31244
474 - samples/gifscale.pl sourced the base value for gif_top from
476 Thanks to Eleneldil G. Arilou for pointing this out.
478 - t/t82inline.t no longer loads B at runtime, to work around a bug
479 in some 5.005_0[45] installations.
480 http://rt.cpan.org/Ticket/Display.html?id=30508
482 - work around Module::Depends::Intrusive bug #21229
483 http://rt.cpan.org/Ticket/Display.html?id=30520
485 - the hardinvert filter no-longer inverts the alpha channel.
486 http://rt.cpan.org/Ticket/Display.html?id=30002
488 - the hardinvert filter now supports large samples
490 Imager 0.61_02 - 28 November 2007
493 - major TIFF support re-work
494 http://rt.cpan.org/Ticket/Display.html?id=20329
496 - added a C level image interface for accessing samples from 1-32
497 bits, exposed this at the perl level in getsamples()
499 - the conv filter now works at floating point precision for high bit
502 - added is_bilevel method to test whether an image should be written as
503 a bilevel image if the image format supports it.
505 - added -log-stderr as an Imager import list option
507 - added some important types to Imager::APIRef
509 - added test_image_double() to Imager::Test
513 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
516 - the scale() method with qtype mixing now handles images with an
517 alpha channel correctly.
519 - fixed a broken link from the "animated GIF" entry in the concept index.
520 Thanks to Slaven Rezic.
521 http://rt.cpan.org/Ticket/Display.html?id=30889
523 - on some perl's the infix expression parser test would fail due to
524 actions in the grammar returning false. Made sure all actions return
526 Thanks to Richard Fairhurst for spending a lot of time in tracking
528 http://rt.cpan.org/Public/Bug/Display.html?id=29562
530 Imager 0.61 - 5 November 2007
533 - added samples/gifscale.pl, which adjusts the screen size/position tags
534 when scaling an animated gif
535 http://rt.cpan.org/Ticket/Display.html?id=27591
539 - correct handling of sz in matrix_transform() - this should allow
540 perspective type transformations to work now.
541 http://rt.cpan.org/Ticket/Display.html?id=29936
543 - prevent a cast to integer warning on x64 builds in datatypes.c
544 also fixed some other type warnings
545 https://rt.cpan.org/Ticket/Display.html?id=30204
547 - some sub-directory tests depended on files produced by the parent
549 http://rt.cpan.org/Ticket/Display.html?id=30203
551 - Imager::Font::Wrap doesn't correctly set savepos
552 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
553 http://rt.cpan.org/Ticket/Display.html?id=29771
555 - test 171 in t/t01introvert.t was failing on perls configured to
557 http://rt.cpan.org/Ticket/Display.html?id=29413
559 - the code for the transform2() uminus operator was missing a break.
560 Added tests for better code coverage of the ops.
561 http://rt.cpan.org/Ticket/Display.html?id=29296
563 - the SGI RLE compression code could overflow its compression buffer
564 http://rt.cpan.org/Ticket/Display.html?id=30334
566 - the 32-bit output function used by the SGI code only handled values
567 under 0x10000. This was most noticable when writing large RLE images.
568 http://rt.cpan.org/Ticket/Display.html?id=30335
570 - validate chan_count for chans == NULL for each of the i_gsamp()
572 http://rt.cpan.org/Ticket/Display.html?id=28985
574 - attempt to work around the test failure at
575 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
576 http://rt.cpan.org/Ticket/Display.html?id=29562
578 - improve the error messages produced when attempting to read or write
579 an unknown image file format.
580 http://rt.cpan.org/Ticket/Display.html?id=30103
582 - improve the transform2() documentation
583 http://rt.cpan.org/Ticket/Display.html?id=29267
585 - correctly generate the author key in META.yml
586 http://rt.cpan.org/Ticket/Display.html?id=30377
588 - correctly blend a rotated (or matrix_transformed()) image when
589 performing interpolation in the presence of an alpha channel.
590 Also corrected the centring of the rotated image on the output
593 Imager 0.60 - 30 August 2007
596 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
597 now has full SGI RGB image format, including RLE and 16-bit/sample
599 https://rt.cpan.org/Ticket/Display.html?id=8666
601 - logging functions are now available in the API
603 - applied Gabriel Vasseur's patch
604 added documentation, further tests, and support for greyscale images
605 Obviously problems are my fault :)
606 https://rt.cpan.org/Ticket/Display.html?id=28142
608 - the mask for ICO/CUR images is now applied as an alpha channel to
609 the returned image. For the old behaviour, supply ico_masked => 0
610 to read() or read_multi(). This should be less confusing when
611 using Imager as a general image processor.
612 https://rt.cpan.org/Ticket/Display.html?id=29001
616 - in some cases it's possible for giflib/libungif to return color
617 indexes outside the range of colors defined by the image's palette.
618 We now expand the palette to match the indexes used.
619 Thanks to Gabriel Vasseur for reporting this.
621 - fixed various memory leaks that could occur when failing to read png,
622 jpeg, bmp or tga files.
624 - to avoid confusion, channels not present in the image are returned as
625 zero by getscanline(). This has no effect on the C level i_glin()
626 and i_glinf() API functions which continue to not set the unused
629 - the convert() method now returns an image of the same sample size as
631 https://rt.cpan.org/Ticket/Display.html?id=28492
633 - remove repeated text in Imager::Files
634 http://rt.cpan.org/Ticket/Display.html?id=27589
636 - be even more explicit that scale() and friends don't modify the source
637 image, but return a new image.
638 http://rt.cpan.org/Ticket/Display.html?id=28570
640 - improve the error message from errstr() when you try to load a font
641 for which the driver hasn't been built in Imager.
642 http://rt.cpan.org/Ticket/Display.html?id=27571
644 - transparency is now enabled by default when writing GIF images
645 http://rt.cpan.org/Ticket/Display.html?id=27615
647 - Imager would not load on Windows 98
648 http://rt.cpan.org/Ticket/Display.html?id=27653
650 Imager 0.59 - 14 June 2007
655 - fixes a regression introduced by the fixes for RT 11972
656 http://rt.cpan.org/Ticket/Display.html?id=27546
658 - cropping outside the image would return an Imager object with
659 no low-level image object, instead of returning false.
660 Fixed by: Philip Gwyn (Leolo)
661 http://rt.cpan.org/Ticket/Display.html?id=27509
663 Imager 0.58 - 16 May 2007
666 No significant changes from 0.57_01.
668 Imager 0.57_01 - 11 May 2007
671 - added to_rgb16 to produce a 16-bit/sample version of an image
673 - improve freetype 1.x text output efficiency
677 - search another place for rgb.txt, and check all the places
678 Imager::Color checks when deciding whether to skip testing it
679 http://rt.cpan.org/Ticket/Display.html?id=26064
681 - use a convolution kernel size based on the stddev rather than a
682 fixed size when performing a gaussian blur
683 http://rt.cpan.org/Ticket/Display.html?id=25645
685 - document the difference() method's mindist parameter, and debug it.
687 - put the Imager release number in the Inline::C generated code to
688 regenerate Inline code when a new release of Imager is installed.
689 http://rt.cpan.org/Ticket/Display.html?id=26278
691 - fix rendering on alpha channel images for the FreeType 1.x driver.
692 http://rt.cpan.org/Ticket/Display.html?id=11972
694 - fix rendering on alpha channel images for the T1lib driver.
695 http://rt.cpan.org/Ticket/Display.html?id=11972
697 - reworked library probing, we can now set more than one probe
698 function for a library. Disabled the default (non-freetype-config)
699 library probe and added an extra probe function that searches for
700 both ft2build.h and whatever it includes, and adds -I as needed.
701 Hopefully this will fix build problems like

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