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 the fix
30 improves performance of supplying colors by name by about 80 times.
31 Test code that managed 3400 10x10 pixel boxes/second sped up to
34 - clarify that Imager doesn't write EXIF metadata to images.
35 https://rt.cpan.org/Ticket/Display.html?id=60637
37 - Imager::Probe can now search subdirectories under its include path.
38 Used by the PNG Makefile.PL to find headers and libraries when they
39 aren't in the base directory, as in cygwin.
40 https://rt.cpan.org/Ticket/Display.html?id=60635
42 Imager 0.77 - 11 Aug 2010
45 I don't want Imager::File::PNG indexed as part of Imager, but forgot
46 to update the META.yml before updating the version.
48 - don't index Imager::File::PNG as part of Imager
50 - add resources to META.yml
52 Imager 0.76 - not released
57 - the align_string() method would ignore a string of "0" due to a
59 Thanks to Maurice Height for reporting this.
60 https://rt.cpan.org/Ticket/Display.html?id=60199
62 Imager 0.75_03 - 09 Aug 2010
67 - read_types() and write_types() would include png when it wasn't
68 available due to a problem with the %formats tie
70 - handle dependent libraries correctly (eg -lpng requiring -lz) in
71 the code run phase of library probing.
73 Imager 0.75_02 - 07 Aug 2010
78 - add file missing from MANIFEST, which was causing TIFF failures.
80 Imager 0.75_01 - 06 Aug 2010
83 Test release for the new PNG probe.
85 - added the ability to read multiple-image PNM files.
86 Note that unlike the pbm/pgm/ppm specification this accepts mixed
87 format files and allows white space padding between files.
88 Thanks to Philip Gwyn (Leolo) for this patch.
90 - moved the PNG file handling code into a sub-module in preparation
91 for separate distribution.
92 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
93 Also helps avoid complications from -I/-L compile/link options from
98 - Imager->new(data => $data) didn't try to process image file data in
100 https://rt.cpan.org/Ticket/Display.html?id=58761
102 - t/t50basicoo.t no longer depends on the other tests to generate its
104 https://rt.cpan.org/Ticket/Display.html?id=9798
105 Also, it wasn't testing pnm (pnm vs ppm mix-up)
107 - update the documentation of hardinvert to match the change in 0.62.
108 https://rt.cpan.org/Ticket/Display.html?id=59785
110 - added hardinvertall filter which also inverts the alpha channel
113 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
114 the probe can find the library for the test run.
115 https://rt.cpan.org/Ticket/Display.html?id=57518
117 Imager 0.75 - 20 Jun 2010
120 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
125 - an opacity fill based on a fountain fill would segfault when
126 filling an 8-bit/sample image.
128 - merge thickline branch polygon fix
129 https://rt.cpan.org/Ticket/Display.html?id=43518
131 Imager 0.74 - 7 May 2010
136 - read_multi() didn't handle a missing file format library correctly,
137 aborting on failing to call i_readgif_multi_wiol() or
138 i_readtiff_multi_wiol().
140 - fix spelling errors patched by Debian
141 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
143 - add an (unshipped) author test to spellcheck Imager's POD.
145 - update the TIFF file format documentation
146 https://rt.cpan.org/Ticket/Display.html?id=56510
148 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
150 Imager 0.73 - 15 Mar 2010
153 - implement outline circles, both anti-aliased and not
154 https://rt.cpan.org/Ticket/Display.html?id=19755
156 - a combine => "none" fill to a 1 or 3 channel image would produce
157 the incorrect colour.
159 Imager 0.72 - 09 Dec 2009
162 Bump version for release, since 0.71_03 is stable with CPAN testers.
164 Imager 0.71_03 - 5 Dec 2009
167 - further adjust the threads test so it only performs the tests on
168 perls where it's expected to work, and only if the threads module
171 Imager 0.71_02 - 1 Dec 2009
174 - adjust the way we load the threads module for the threads test so
175 it works with non-threaded perls
177 Imager 0.71_01 - 30 Nov 2009
182 - use scanline oriented operations to flip images instead of pixel
184 https://rt.cpan.org/Ticket/Display.html?id=39278
186 - use double/sample operations to flip large sample images instead of
187 8-bit sample operations.
188 https://rt.cpan.org/Ticket/Display.html?id=39280
191 https://rt.cpan.org/Ticket/Display.html?id=51874
193 - prevent double-frees when someone creates Imager objects and then
194 creates a thread. Note: this just handles some simple cases,
195 Imager doesn't support perl threads, and isn't likely to.
196 https://rt.cpan.org/Ticket/Display.html?id=52268
198 Imager 0.71 - 16 Nov 2009
201 - add the opacity fill type - an adaptor that modifies the opacity of
206 - the conv filter now enforces that the sum of the coefficients is
207 non-zero. Also, rather than skipping pixels off the edge off the
208 edge of the image, the closest edge pixel is used. Previously
209 dividing by the zero sum of coefficients could cause invalid
210 results or runtime exceptions.
211 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
214 Imager 0.70 - 21 Sep 2009
219 - release image row and comments memory on all error returns in gif
222 - handle zero length extensions, previously this would cause a null
224 Thanks to Krzysztof WojtaÅ for the test data and fix for this.
226 - an integer division meant that preview scaling to below 1 pixel
227 wide or high (which isn't too useful anyway) was calculating using
228 NaNs on most platforms, and causing an exception on others.
229 Thanks to David Cantrell for producing a backtrace of the crash on
230 his Alpha-NetBSD CPAN test box which made it possible to track this
233 Imager 0.69 - 08 Sep 2009
238 - broken test fix - was attempting to call a function skip_all, when
239 that should be a parameter to plan().
241 - briefly document apidocs.perl, the tool used to build
242 Imager::APIRef and make some minor enhancements
244 - various minor documentation enhancements and fixes.
246 Imager 0.68 - 07 Sep 2009
249 - Imager->new(file => $filename) and other similar incantations will
251 https://rt.cpan.org/Ticket/Display.html?id=48261
255 - avoid using CHECK as a label in Imager::Test
256 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
258 - re-work most image file test files that require a library into
259 separate library present/not present files to remove stupidly long
262 - don't treat rubthrough() outside the bounds of the target image as
264 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
266 Imager 0.67_01 - 02 Sep 2009
271 - correct documentation of default of raw image interleave read
273 https://rt.cpan.org/Ticket/Display.html?id=42074
275 - add raw_ prefix to raw read parameters, though the original names
278 - fail the read if an invalid raw_interleave parameter is supplied
280 - warn if no interleave or raw_interleave parameter is supplied,
281 since the documented default was wrong, and incompatible with the
284 - for reading raw images, if raw_storechannels > raw_datachannels,
285 set the extra channels in the image to 0
287 - when probing for executables like freetype-config, search for .bat
288 and .cmd on MSWin32, as well as .exe.
289 https://rt.cpan.org/Ticket/Display.html?id=49275
291 - re-work the external libraries section of README:
292 - list Debian and Redhat package names for each library
296 - use the new EU::MM META_MERGE facility instead of generating
297 META.yml from scratch
298 https://rt.cpan.org/Ticket/Display.html?id=47888
300 - use Devel::CheckLib (bundled, modified) to check which release of
301 libtiff is installed and reject 3.9.0
302 http://bugzilla.maptools.org/show_bug.cgi?id=2088
303 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
305 Imager 0.67 - 12 Dec 2008
310 - fix a packaging error
312 Imager 0.66 - 12 Dec 2008
315 - 24-bit color .ICO/.CUR files can now be read.
319 - an optimization skipping 0 src alpha values could cause the
320 rubthrough() to read past the end of a buffer.
321 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
323 - corrected a reference leak where writing GIFs would leak memory.
324 This could also happen calling to_paletted().
325 Also documented the underlying long existing feature where the
326 colors parameter is filled with the generated color table and added
328 http://rt.cpan.org/Ticket/Display.html?id=41028
330 - write out the image size in bytes field of a BMP correctly.
331 http://rt.cpan.org/Ticket/Display.html?id=41406
333 - add limited tests for Imager::ExtUtils
335 - make Imager::ExtUtils->includes use an absolute path, since
336 a relative path could cause failures using Inline::C.
337 http://rt.cpan.org/Ticket/Display.html?id=37353
339 - re-arrange the POD for Imager::Font::BBox:
340 - mark total_width(), pos_width(), end_offset() obsolete, since
341 they're mostly for backwards compatibility
342 - group width methods and height methods
343 https://rt.cpan.org/Ticket/Display.html?id=39999
345 Imager 0.65 - 20 May 2008
350 - In some cases when an error occurs reading those parts of a JPEG
351 file after the image the scan-line buffer could be freed a second
352 time. In cases where the the error occured while reading the image
353 data it's possible that the buffer could have leaked.
354 Thanks to Gabriel Vasseur for reporting this and help in tracking
357 - the gif_screen_height tag was overriding the screen width and being
358 ignored for the screen height when present.
359 https://rt.cpan.org/Public/Bug/Display.html?id=35568
361 Imager 0.64 - 23 April 2008
364 This is a bug fix release. This includes a fix for a possible
369 - Possible security issue: The floating point sample path for image
370 based fills had a buffer overflow. This would overwrite the end of
371 a malloc()ed buffer with double precision floats.
372 http://rt.cpan.org/Ticket/Display.html?id=35324
375 - check that the result of fileno($fh) is defined rather than simply
376 true when read() or write() is supplied with an fh parameter.
377 http://rt.cpan.org/Ticket/Display.html?id=35139
379 - i_scale_axis() wasn't checking the result of i_img_new_ch()
380 resulting in a SIGSEGV when attempting to scale an image to a size
381 too large to fit in memory. This is a NULL pointer access issue,
382 not a buffer overflow.
383 Added a check for the failure.
384 scale_calculate() (and hence scale()) will now fail if any of the
385 scale size parameters are a reference.
386 http://rt.cpan.org/Ticket/Display.html?id=35172
388 - Regression: filling a greyscale image with a hatch used the wrong
389 color channels from the supplied fg/bg colors.
390 https://rt.cpan.org/Ticket/Display.html?id=35278
392 - fixed a related problem for image fills.
394 Imager 0.63 - 7 April 2008
397 This release primarily contains changes to improve ease of use -
398 rather than you having to convert images to the appropriate number of
399 channels, Imager handles it internally. How to handle drawing colors
400 and the default combine mode is a thornier problem left for some other
403 - the font libraries are now only initialized when needed.
404 http://rt.cpan.org/Ticket/Display.html?id=28825
406 - moved the imtoc.perl code into Imager::Preprocess
408 - paste() and rubthrough() now adapt the source image data to the
409 destination, so you can now safely paste/rubthrough from greyscale
410 images to color images or back, or from alpha channel images to
411 noalpha channels or back.
412 https://rt.cpan.org/Ticket/Display.html?id=30908
414 - rubthrough() now falls back to pasting when the source doesn't have
415 an alpha channel. This effectively treats the source as having a
416 max alpha channel, the right thing to do.
417 http://rt.cpan.org/Ticket/Display.html?id=29944
419 - re-worked most of the area filling code to use a common set of
420 functions when filling.
421 Corrected normal combine mode.
422 Rewrote most of the combine modes to match the way the SVG draft
423 defines them with respect to a translucent source and destination.
424 Added tests for translucent source and destination.
425 Added tests to check 8-bit/sample and double/sample combines work
427 https://rt.cpan.org/Ticket/Display.html?id=29879
429 - writing a 2 or 4 channel image to a JPEG file will now write that
430 image as if composited against a background, black by default,
431 overridable with the i_background tag/parameter.
432 https://rt.cpan.org/Ticket/Display.html?id=29876
434 - writing a 2 or 4 channel image to a PGM/PPM file will now write
435 that image as if composited against a background, black by default,
436 overridable with the i_background tag/parameter.
437 http://rt.cpan.org/Ticket/Display.html?id=30074
439 - writing a 2 or 4 channel image to a BMP file will now write that
440 image as if composited against a background, black by default,
441 overridable with the i_background tag/parameter.
442 http://rt.cpan.org/Ticket/Display.html?id=30075
446 - Imager::Matrix2d->translate() now only requires one of the x or y
448 http://rt.cpan.org/Ticket/Display.html?id=29937
450 - mixing qtype scaling now sets all channels of a pixel to zero if
451 the pixel has zero coverage (zero alpha). This should produce more
452 compressible output files.
453 http://rt.cpan.org/Ticket/Display.html?id=32324
455 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
457 https://bugzilla.redhat.com/show_bug.cgi?id=166254
458 I'm not changing the #! lines of the sample code, since it's sample
459 code, not intended for installation.
460 http://rt.cpan.org/Ticket/Display.html?id=33408
462 - some TGA images weren't being detected correctly as TGA images
463 https://rt.cpan.org/Ticket/Display.html?id=32925
465 - handling of the left-over bit for 16-bit/pixel TGA images has been
466 changed to match the behaviour of the GIMP. Previously the bit
467 being set was treated as an opaque pixel, but one user reported a
468 problem with loading such an image. I haven't been able to find any
469 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
470 I'll match it's behaviour. See issue 114913 in the GIMP's
472 http://rt.cpan.org/Ticket/Display.html?id=32926
474 Imager 0.62 - 10 December 2007
477 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
478 to /path under your home directory.
479 http://rt.cpan.org/Ticket/Display.html?id=29484
481 - the old dynaload code used Mach API functions to load dynamic
482 libraries on Mac OS X. These APIs have been deprecated in OS X
483 10.5 and were causing some build problems.
484 So henceforth Imager uses the dlopen() family of functions, and you
485 will need version 10.3 or later of OS X.
487 - added the det() function to the transform2() engine.
488 added the sample quad_to_square.pl
489 Courtesy Richard Fairhurst.
490 http://rt.cpan.org/Ticket/Display.html?id=31244
494 - samples/gifscale.pl sourced the base value for gif_top from
496 Thanks to Eleneldil G. Arilou for pointing this out.
498 - t/t82inline.t no longer loads B at runtime, to work around a bug
499 in some 5.005_0[45] installations.
500 http://rt.cpan.org/Ticket/Display.html?id=30508
502 - work around Module::Depends::Intrusive bug #21229
503 http://rt.cpan.org/Ticket/Display.html?id=30520
505 - the hardinvert filter no-longer inverts the alpha channel.
506 http://rt.cpan.org/Ticket/Display.html?id=30002
508 - the hardinvert filter now supports large samples
510 Imager 0.61_02 - 28 November 2007
513 - major TIFF support re-work
514 http://rt.cpan.org/Ticket/Display.html?id=20329
516 - added a C level image interface for accessing samples from 1-32
517 bits, exposed this at the perl level in getsamples()
519 - the conv filter now works at floating point precision for high bit
522 - added is_bilevel method to test whether an image should be written as
523 a bilevel image if the image format supports it.
525 - added -log-stderr as an Imager import list option
527 - added some important types to Imager::APIRef
529 - added test_image_double() to Imager::Test
533 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
536 - the scale() method with qtype mixing now handles images with an
537 alpha channel correctly.
539 - fixed a broken link from the "animated GIF" entry in the concept index.
540 Thanks to Slaven Rezic.
541 http://rt.cpan.org/Ticket/Display.html?id=30889
543 - on some perl's the infix expression parser test would fail due to
544 actions in the grammar returning false. Made sure all actions return
546 Thanks to Richard Fairhurst for spending a lot of time in tracking
548 http://rt.cpan.org/Public/Bug/Display.html?id=29562
550 Imager 0.61 - 5 November 2007
553 - added samples/gifscale.pl, which adjusts the screen size/position tags
554 when scaling an animated gif
555 http://rt.cpan.org/Ticket/Display.html?id=27591
559 - correct handling of sz in matrix_transform() - this should allow
560 perspective type transformations to work now.
561 http://rt.cpan.org/Ticket/Display.html?id=29936
563 - prevent a cast to integer warning on x64 builds in datatypes.c
564 also fixed some other type warnings
565 https://rt.cpan.org/Ticket/Display.html?id=30204
567 - some sub-directory tests depended on files produced by the parent
569 http://rt.cpan.org/Ticket/Display.html?id=30203
571 - Imager::Font::Wrap doesn't correctly set savepos
572 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
573 http://rt.cpan.org/Ticket/Display.html?id=29771
575 - test 171 in t/t01introvert.t was failing on perls configured to
577 http://rt.cpan.org/Ticket/Display.html?id=29413
579 - the code for the transform2() uminus operator was missing a break.
580 Added tests for better code coverage of the ops.
581 http://rt.cpan.org/Ticket/Display.html?id=29296
583 - the SGI RLE compression code could overflow its compression buffer
584 http://rt.cpan.org/Ticket/Display.html?id=30334
586 - the 32-bit output function used by the SGI code only handled values
587 under 0x10000. This was most noticable when writing large RLE images.
588 http://rt.cpan.org/Ticket/Display.html?id=30335
590 - validate chan_count for chans == NULL for each of the i_gsamp()
592 http://rt.cpan.org/Ticket/Display.html?id=28985
594 - attempt to work around the test failure at
595 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
596 http://rt.cpan.org/Ticket/Display.html?id=29562
598 - improve the error messages produced when attempting to read or write
599 an unknown image file format.
600 http://rt.cpan.org/Ticket/Display.html?id=30103
602 - improve the transform2() documentation
603 http://rt.cpan.org/Ticket/Display.html?id=29267
605 - correctly generate the author key in META.yml
606 http://rt.cpan.org/Ticket/Display.html?id=30377
608 - correctly blend a rotated (or matrix_transformed()) image when
609 performing interpolation in the presence of an alpha channel.
610 Also corrected the centring of the rotated image on the output
613 Imager 0.60 - 30 August 2007
616 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
617 now has full SGI RGB image format, including RLE and 16-bit/sample
619 https://rt.cpan.org/Ticket/Display.html?id=8666
621 - logging functions are now available in the API
623 - applied Gabriel Vasseur's patch
624 added documentation, further tests, and support for greyscale images
625 Obviously problems are my fault :)
626 https://rt.cpan.org/Ticket/Display.html?id=28142
628 - the mask for ICO/CUR images is now applied as an alpha channel to
629 the returned image. For the old behaviour, supply ico_masked => 0
630 to read() or read_multi(). This should be less confusing when
631 using Imager as a general image processor.
632 https://rt.cpan.org/Ticket/Display.html?id=29001
636 - in some cases it's possible for giflib/libungif to return color
637 indexes outside the range of colors defined by the image's palette.
638 We now expand the palette to match the indexes used.
639 Thanks to Gabriel Vasseur for reporting this.
641 - fixed various memory leaks that could occur when failing to read png,
642 jpeg, bmp or tga files.
644 - to avoid confusion, channels not present in the image are returned as
645 zero by getscanline(). This has no effect on the C level i_glin()
646 and i_glinf() API functions which continue to not set the unused
649 - the convert() method now returns an image of the same sample size as
651 https://rt.cpan.org/Ticket/Display.html?id=28492
653 - remove repeated text in Imager::Files
654 http://rt.cpan.org/Ticket/Display.html?id=27589
656 - be even more explicit that scale() and friends don't modify the source
657 image, but return a new image.
658 http://rt.cpan.org/Ticket/Display.html?id=28570
660 - improve the error message from errstr() when you try to load a font
661 for which the driver hasn't been built in Imager.
662 http://rt.cpan.org/Ticket/Display.html?id=27571

719 library probe and added an extra probe function that searches for
720 both ft2build.h and whatever it includes, and adds -I as needed.
721 Hopefully this will fix build problems like

728 This is a maintenence release fixing a security issue in Imager.
730 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
731 overflow in malloced memory. There will be further discussion of
732 this issue in the ticket below.

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