7 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
8 Uses Imager::Probe now.
9 https://rt.cpan.org/Public/Bug/Display.html?id=61328
11 - tested successfully with jpeg-8b
12 https://rt.cpan.org/Ticket/Display.html?id=60221
16 - from _01: look for missing file support test files in the right
19 - flood_fill() wouldn't fill the right side of a single scan-line
21 Thanks to Nicolas Roggli for reporting this.
23 - flood_fill wouldn't fill to the left edge of the image if the
24 starting line didn't reach the left edge.
25 Thanks to Nicolas Roggli for reporting this.
27 Imager 0.77_01 - 13 Sep 2010
30 - add each library-directory/pkgconfig/ to the pkg-config search path
32 Thanks to Justin Davis.
33 https://rt.cpan.org/Ticket/Display.html?id=60491
35 - moved GIF, TIFF, JPEG file handling code into sub-modules in
36 preparation for separate distribution.
37 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
39 - optimize filled box drawing (color, not fill)
43 - Imager::Probe was calling ExtUtils::Liblist to initialize
44 LD_RUN_PATH supplying an undefined value rather than the found
45 directory. Thanks to Justin Davis.
46 https://rt.cpan.org/Ticket/Display.html?id=60491
48 - only prepend ./ to font filenames when passing them to T1Lib and
49 then only when it would use its search mechanisms.
50 https://rt.cpan.org/Ticket/Display.html?id=60509
52 - fix the cache check for the X rgb.txt loader. This is typically
53 used for color translation on Unix-like systems, and the fix
54 improves performance of supplying colors by name by about 80 times.
55 Test code that managed 3400 10x10 pixel boxes/second sped up to
58 - clarify that Imager doesn't write EXIF metadata to images.
59 https://rt.cpan.org/Ticket/Display.html?id=60637
61 - Imager::Probe can now search subdirectories under its include path.
62 Used by the PNG Makefile.PL to find headers and libraries when they
63 aren't in the base directory, as in cygwin.
64 https://rt.cpan.org/Ticket/Display.html?id=60635
66 Imager 0.77 - 11 Aug 2010
69 I don't want Imager::File::PNG indexed as part of Imager, but forgot
70 to update the META.yml before updating the version.
72 - don't index Imager::File::PNG as part of Imager
74 - add resources to META.yml
76 Imager 0.76 - not released
81 - the align_string() method would ignore a string of "0" due to a
83 Thanks to Maurice Height for reporting this.
84 https://rt.cpan.org/Ticket/Display.html?id=60199
86 Imager 0.75_03 - 09 Aug 2010
91 - read_types() and write_types() would include png when it wasn't
92 available due to a problem with the %formats tie
94 - handle dependent libraries correctly (eg -lpng requiring -lz) in
95 the code run phase of library probing.
97 Imager 0.75_02 - 07 Aug 2010
102 - add file missing from MANIFEST, which was causing TIFF failures.
104 Imager 0.75_01 - 06 Aug 2010
107 Test release for the new PNG probe.
109 - added the ability to read multiple-image PNM files.
110 Note that unlike the pbm/pgm/ppm specification this accepts mixed
111 format files and allows white space padding between files.
112 Thanks to Philip Gwyn (Leolo) for this patch.
114 - moved the PNG file handling code into a sub-module in preparation
115 for separate distribution.
116 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
117 Also helps avoid complications from -I/-L compile/link options from
122 - Imager->new(data => $data) didn't try to process image file data in
124 https://rt.cpan.org/Ticket/Display.html?id=58761
126 - t/t50basicoo.t no longer depends on the other tests to generate its
128 https://rt.cpan.org/Ticket/Display.html?id=9798
129 Also, it wasn't testing pnm (pnm vs ppm mix-up)
131 - update the documentation of hardinvert to match the change in 0.62.
132 https://rt.cpan.org/Ticket/Display.html?id=59785
134 - added hardinvertall filter which also inverts the alpha channel
137 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
138 the probe can find the library for the test run.
139 https://rt.cpan.org/Ticket/Display.html?id=57518
141 Imager 0.75 - 20 Jun 2010
144 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
149 - an opacity fill based on a fountain fill would segfault when
150 filling an 8-bit/sample image.
152 - merge thickline branch polygon fix
153 https://rt.cpan.org/Ticket/Display.html?id=43518
155 Imager 0.74 - 7 May 2010
160 - read_multi() didn't handle a missing file format library correctly,
161 aborting on failing to call i_readgif_multi_wiol() or
162 i_readtiff_multi_wiol().
164 - fix spelling errors patched by Debian
165 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
167 - add an (unshipped) author test to spellcheck Imager's POD.
169 - update the TIFF file format documentation
170 https://rt.cpan.org/Ticket/Display.html?id=56510
172 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
174 Imager 0.73 - 15 Mar 2010
177 - implement outline circles, both anti-aliased and not
178 https://rt.cpan.org/Ticket/Display.html?id=19755
180 - a combine => "none" fill to a 1 or 3 channel image would produce
181 the incorrect colour.
183 Imager 0.72 - 09 Dec 2009
186 Bump version for release, since 0.71_03 is stable with CPAN testers.
188 Imager 0.71_03 - 5 Dec 2009
191 - further adjust the threads test so it only performs the tests on
192 perls where it's expected to work, and only if the threads module
195 Imager 0.71_02 - 1 Dec 2009
198 - adjust the way we load the threads module for the threads test so
199 it works with non-threaded perls
201 Imager 0.71_01 - 30 Nov 2009
206 - use scanline oriented operations to flip images instead of pixel
208 https://rt.cpan.org/Ticket/Display.html?id=39278
210 - use double/sample operations to flip large sample images instead of
211 8-bit sample operations.
212 https://rt.cpan.org/Ticket/Display.html?id=39280
215 https://rt.cpan.org/Ticket/Display.html?id=51874
217 - prevent double-frees when someone creates Imager objects and then
218 creates a thread. Note: this just handles some simple cases,
219 Imager doesn't support perl threads, and isn't likely to.
220 https://rt.cpan.org/Ticket/Display.html?id=52268
222 Imager 0.71 - 16 Nov 2009
225 - add the opacity fill type - an adaptor that modifies the opacity of
230 - the conv filter now enforces that the sum of the coefficients is
231 non-zero. Also, rather than skipping pixels off the edge off the
232 edge of the image, the closest edge pixel is used. Previously
233 dividing by the zero sum of coefficients could cause invalid
234 results or runtime exceptions.
235 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
238 Imager 0.70 - 21 Sep 2009
243 - release image row and comments memory on all error returns in gif
246 - handle zero length extensions, previously this would cause a null
248 Thanks to Krzysztof WojtaÅ for the test data and fix for this.
250 - an integer division meant that preview scaling to below 1 pixel
251 wide or high (which isn't too useful anyway) was calculating using
252 NaNs on most platforms, and causing an exception on others.
253 Thanks to David Cantrell for producing a backtrace of the crash on
254 his Alpha-NetBSD CPAN test box which made it possible to track this
257 Imager 0.69 - 08 Sep 2009
262 - broken test fix - was attempting to call a function skip_all, when
263 that should be a parameter to plan().
265 - briefly document apidocs.perl, the tool used to build
266 Imager::APIRef and make some minor enhancements
268 - various minor documentation enhancements and fixes.
270 Imager 0.68 - 07 Sep 2009
273 - Imager->new(file => $filename) and other similar incantations will
275 https://rt.cpan.org/Ticket/Display.html?id=48261
279 - avoid using CHECK as a label in Imager::Test
280 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
282 - re-work most image file test files that require a library into
283 separate library present/not present files to remove stupidly long
286 - don't treat rubthrough() outside the bounds of the target image as
288 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
290 Imager 0.67_01 - 02 Sep 2009
295 - correct documentation of default of raw image interleave read
297 https://rt.cpan.org/Ticket/Display.html?id=42074
299 - add raw_ prefix to raw read parameters, though the original names
302 - fail the read if an invalid raw_interleave parameter is supplied
304 - warn if no interleave or raw_interleave parameter is supplied,
305 since the documented default was wrong, and incompatible with the
308 - for reading raw images, if raw_storechannels > raw_datachannels,
309 set the extra channels in the image to 0
311 - when probing for executables like freetype-config, search for .bat
312 and .cmd on MSWin32, as well as .exe.
313 https://rt.cpan.org/Ticket/Display.html?id=49275
315 - re-work the external libraries section of README:
316 - list Debian and Redhat package names for each library
320 - use the new EU::MM META_MERGE facility instead of generating
321 META.yml from scratch
322 https://rt.cpan.org/Ticket/Display.html?id=47888
324 - use Devel::CheckLib (bundled, modified) to check which release of
325 libtiff is installed and reject 3.9.0
326 http://bugzilla.maptools.org/show_bug.cgi?id=2088
327 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
329 Imager 0.67 - 12 Dec 2008
334 - fix a packaging error
336 Imager 0.66 - 12 Dec 2008
339 - 24-bit color .ICO/.CUR files can now be read.
343 - an optimization skipping 0 src alpha values could cause the
344 rubthrough() to read past the end of a buffer.
345 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
347 - corrected a reference leak where writing GIFs would leak memory.
348 This could also happen calling to_paletted().
349 Also documented the underlying long existing feature where the
350 colors parameter is filled with the generated color table and added
352 http://rt.cpan.org/Ticket/Display.html?id=41028
354 - write out the image size in bytes field of a BMP correctly.
355 http://rt.cpan.org/Ticket/Display.html?id=41406
357 - add limited tests for Imager::ExtUtils
359 - make Imager::ExtUtils->includes use an absolute path, since
360 a relative path could cause failures using Inline::C.
361 http://rt.cpan.org/Ticket/Display.html?id=37353
363 - re-arrange the POD for Imager::Font::BBox:
364 - mark total_width(), pos_width(), end_offset() obsolete, since
365 they're mostly for backwards compatibility
366 - group width methods and height methods
367 https://rt.cpan.org/Ticket/Display.html?id=39999
369 Imager 0.65 - 20 May 2008
374 - In some cases when an error occurs reading those parts of a JPEG
375 file after the image the scan-line buffer could be freed a second
376 time. In cases where the the error occured while reading the image
377 data it's possible that the buffer could have leaked.
378 Thanks to Gabriel Vasseur for reporting this and help in tracking
381 - the gif_screen_height tag was overriding the screen width and being
382 ignored for the screen height when present.
383 https://rt.cpan.org/Public/Bug/Display.html?id=35568
385 Imager 0.64 - 23 April 2008
388 This is a bug fix release. This includes a fix for a possible
393 - Possible security issue: The floating point sample path for image
394 based fills had a buffer overflow. This would overwrite the end of
395 a malloc()ed buffer with double precision floats.
396 http://rt.cpan.org/Ticket/Display.html?id=35324
399 - check that the result of fileno($fh) is defined rather than simply
400 true when read() or write() is supplied with an fh parameter.
401 http://rt.cpan.org/Ticket/Display.html?id=35139
403 - i_scale_axis() wasn't checking the result of i_img_new_ch()
404 resulting in a SIGSEGV when attempting to scale an image to a size
405 too large to fit in memory. This is a NULL pointer access issue,
406 not a buffer overflow.
407 Added a check for the failure.
408 scale_calculate() (and hence scale()) will now fail if any of the
409 scale size parameters are a reference.
410 http://rt.cpan.org/Ticket/Display.html?id=35172
412 - Regression: filling a greyscale image with a hatch used the wrong
413 color channels from the supplied fg/bg colors.
414 https://rt.cpan.org/Ticket/Display.html?id=35278
416 - fixed a related problem for image fills.
418 Imager 0.63 - 7 April 2008
421 This release primarily contains changes to improve ease of use -
422 rather than you having to convert images to the appropriate number of
423 channels, Imager handles it internally. How to handle drawing colors
424 and the default combine mode is a thornier problem left for some other
427 - the font libraries are now only initialized when needed.
428 http://rt.cpan.org/Ticket/Display.html?id=28825
430 - moved the imtoc.perl code into Imager::Preprocess
432 - paste() and rubthrough() now adapt the source image data to the
433 destination, so you can now safely paste/rubthrough from greyscale
434 images to color images or back, or from alpha channel images to
435 noalpha channels or back.
436 https://rt.cpan.org/Ticket/Display.html?id=30908
438 - rubthrough() now falls back to pasting when the source doesn't have
439 an alpha channel. This effectively treats the source as having a
440 max alpha channel, the right thing to do.
441 http://rt.cpan.org/Ticket/Display.html?id=29944
443 - re-worked most of the area filling code to use a common set of
444 functions when filling.
445 Corrected normal combine mode.
446 Rewrote most of the combine modes to match the way the SVG draft
447 defines them with respect to a translucent source and destination.
448 Added tests for translucent source and destination.
449 Added tests to check 8-bit/sample and double/sample combines work
451 https://rt.cpan.org/Ticket/Display.html?id=29879
453 - writing a 2 or 4 channel image to a JPEG file will now write that
454 image as if composited against a background, black by default,
455 overridable with the i_background tag/parameter.
456 https://rt.cpan.org/Ticket/Display.html?id=29876
458 - writing a 2 or 4 channel image to a PGM/PPM file will now write
459 that image as if composited against a background, black by default,
460 overridable with the i_background tag/parameter.
461 http://rt.cpan.org/Ticket/Display.html?id=30074
463 - writing a 2 or 4 channel image to a BMP file will now write that
464 image as if composited against a background, black by default,
465 overridable with the i_background tag/parameter.
466 http://rt.cpan.org/Ticket/Display.html?id=30075
470 - Imager::Matrix2d->translate() now only requires one of the x or y
472 http://rt.cpan.org/Ticket/Display.html?id=29937
474 - mixing qtype scaling now sets all channels of a pixel to zero if
475 the pixel has zero coverage (zero alpha). This should produce more
476 compressible output files.
477 http://rt.cpan.org/Ticket/Display.html?id=32324
479 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
481 https://bugzilla.redhat.com/show_bug.cgi?id=166254
482 I'm not changing the #! lines of the sample code, since it's sample
483 code, not intended for installation.
484 http://rt.cpan.org/Ticket/Display.html?id=33408
486 - some TGA images weren't being detected correctly as TGA images
487 https://rt.cpan.org/Ticket/Display.html?id=32925
489 - handling of the left-over bit for 16-bit/pixel TGA images has been
490 changed to match the behaviour of the GIMP. Previously the bit
491 being set was treated as an opaque pixel, but one user reported a
492 problem with loading such an image. I haven't been able to find any
493 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
494 I'll match it's behaviour. See issue 114913 in the GIMP's
496 http://rt.cpan.org/Ticket/Display.html?id=32926
498 Imager 0.62 - 10 December 2007
501 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
502 to /path under your home directory.
503 http://rt.cpan.org/Ticket/Display.html?id=29484
505 - the old dynaload code used Mach API functions to load dynamic
506 libraries on Mac OS X. These APIs have been deprecated in OS X
507 10.5 and were causing some build problems.
508 So henceforth Imager uses the dlopen() family of functions, and you
509 will need version 10.3 or later of OS X.
511 - added the det() function to the transform2() engine.
512 added the sample quad_to_square.pl
513 Courtesy Richard Fairhurst.
514 http://rt.cpan.org/Ticket/Display.html?id=31244
518 - samples/gifscale.pl sourced the base value for gif_top from
520 Thanks to Eleneldil G. Arilou for pointing this out.
522 - t/t82inline.t no longer loads B at runtime, to work around a bug
523 in some 5.005_0[45] installations.
524 http://rt.cpan.org/Ticket/Display.html?id=30508
526 - work around Module::Depends::Intrusive bug #21229
527 http://rt.cpan.org/Ticket/Display.html?id=30520
529 - the hardinvert filter no-longer inverts the alpha channel.
530 http://rt.cpan.org/Ticket/Display.html?id=30002
532 - the hardinvert filter now supports large samples
534 Imager 0.61_02 - 28 November 2007
537 - major TIFF support re-work
538 http://rt.cpan.org/Ticket/Display.html?id=20329
540 - added a C level image interface for accessing samples from 1-32
541 bits, exposed this at the perl level in getsamples()
543 - the conv filter now works at floating point precision for high bit
546 - added is_bilevel method to test whether an image should be written as
547 a bilevel image if the image format supports it.
549 - added -log-stderr as an Imager import list option
551 - added some important types to Imager::APIRef
553 - added test_image_double() to Imager::Test
557 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
560 - the scale() method with qtype mixing now handles images with an
561 alpha channel correctly.
563 - fixed a broken link from the "animated GIF" entry in the concept index.
564 Thanks to Slaven Rezic.
565 http://rt.cpan.org/Ticket/Display.html?id=30889
567 - on some perl's the infix expression parser test would fail due to
568 actions in the grammar returning false. Made sure all actions return
570 Thanks to Richard Fairhurst for spending a lot of time in tracking
572 http://rt.cpan.org/Public/Bug/Display.html?id=29562
574 Imager 0.61 - 5 November 2007
577 - added samples/gifscale.pl, which adjusts the screen size/position tags
578 when scaling an animated gif
579 http://rt.cpan.org/Ticket/Display.html?id=27591
583 - correct handling of sz in matrix_transform() - this should allow
584 perspective type transformations to work now.
585 http://rt.cpan.org/Ticket/Display.html?id=29936
587 - prevent a cast to integer warning on x64 builds in datatypes.c
588 also fixed some other type warnings
589 https://rt.cpan.org/Ticket/Display.html?id=30204
591 - some sub-directory tests depended on files produced by the parent
593 http://rt.cpan.org/Ticket/Display.html?id=30203
595 - Imager::Font::Wrap doesn't correctly set savepos
596 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
597 http://rt.cpan.org/Ticket/Display.html?id=29771
599 - test 171 in t/t01introvert.t was failing on perls configured to
601 http://rt.cpan.org/Ticket/Display.html?id=29413
603 - the code for the transform2() uminus operator was missing a break.
604 Added tests for better code coverage of the ops.
605 http://rt.cpan.org/Ticket/Display.html?id=29296
607 - the SGI RLE compression code could overflow its compression buffer
608 http://rt.cpan.org/Ticket/Display.html?id=30334
610 - the 32-bit output function used by the SGI code only handled values
611 under 0x10000. This was most noticable when writing large RLE images.
612 http://rt.cpan.org/Ticket/Display.html?id=30335
614 - validate chan_count for chans == NULL for each of the i_gsamp()
616 http://rt.cpan.org/Ticket/Display.html?id=28985
618 - attempt to work around the test failure at
619 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
620 http://rt.cpan.org/Ticket/Display.html?id=29562
622 - improve the error messages produced when attempting to read or write
623 an unknown image file format.
624 http://rt.cpan.org/Ticket/Display.html?id=30103
626 - improve the transform2() documentation
627 http://rt.cpan.org/Ticket/Display.html?id=29267
629 - correctly generate the author key in META.yml
630 http://rt.cpan.org/Ticket/Display.html?id=30377
632 - correctly blend a rotated (or matrix_transformed()) image when
633 performing interpolation in the presence of an alpha channel.
634 Also corrected the centring of the rotated image on the output
637 Imager 0.60 - 30 August 2007
640 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
641 now has full SGI RGB image format, including RLE and 16-bit/sample
643 https://rt.cpan.org/Ticket/Display.html?id=8666
645 - logging functions are now available in the API
647 - applied Gabriel Vasseur's patch
648 added documentation, further tests, and support for greyscale images
649 Obviously problems are my fault :)
650 https://rt.cpan.org/Ticket/Display.html?id=28142
652 - the mask for ICO/CUR images is now applied as an alpha channel to
653 the returned image. For the old behaviour, supply ico_masked => 0
654 to read() or read_multi(). This should be less confusing when
655 using Imager as a general image processor.
656 https://rt.cpan.org/Ticket/Display.html?id=29001
660 - in some cases it's possible for giflib/libungif to return color
661 indexes outside the range of colors defined by the image's palette.
662 We now expand the palette to match the indexes used.
663 Thanks to Gabriel Vasseur for reporting this.
665 - fixed various memory leaks that could occur when failing to read png,
666 jpeg, bmp or tga files.
668 - to avoid confusion, channels not present in the image are returned as
669 zero by getscanline(). This has no effect on the C level i_glin()
670 and i_glinf() API functions which continue to not set the unused
673 - the convert() method now returns an image of the same sample size as
675 https://rt.cpan.org/Ticket/Display.html?id=28492
677 - remove repeated text in Imager::Files
678 http://rt.cpan.org/Ticket/Display.html?id=27589
680 - be even more explicit that scale() and friends don't modify the source
681 image, but return a new image.
682 http://rt.cpan.org/Ticket/Display.html?id=28570
684 - improve the error message from errstr() when you try to load a font
685 for which the driver hasn't been built in Imager.
686 http://rt.cpan.org/Ticket/Display.html?id=27571
688 - transparency is now enabled by default when writing GIF images
689 http://rt.cpan.org/Ticket/Display.html?id=27615
691 - Imager would not load on Windows 98
692 http://rt.cpan.org/Ticket/Display.html?id=27653
694 Imager 0.59 - 14 June 2007
699 - fixes a regression introduced by the fixes for RT 11972
700 http://rt.cpan.org/Ticket/Display.html?id=27546
702 - cropping outside the image would return an Imager object with
703 no low-level image object, instead of returning false.
704 Fixed by: Philip Gwyn (Leolo)
705 http://rt.cpan.org/Ticket/Display.html?id=27509
707 Imager 0.58 - 16 May 2007
710 No significant changes from 0.57_01.
712 Imager 0.57_01 - 11 May 2007
715 - added to_rgb16 to produce a 16-bit/sample version of an image
717 - improve freetype 1.x text output efficiency
721 - search another place for rgb.txt, and check all the places
722 Imager::Color checks when deciding whether to skip testing it
723 http://rt.cpan.org/Ticket/Display.html?id=26064
725 - use a convolution kernel size based on the stddev rather than a
726 fixed size when performing a gaussian blur
727 http://rt.cpan.org/Ticket/Display.html?id=25645
729 - document the difference() method's mindist parameter, and debug it.
731 - put the Imager release number in the Inline::C generated code to
732 regenerate Inline code when a new release of Imager is installed.
733 http://rt.cpan.org/Ticket/Display.html?id=26278
735 - fix rendering on alpha channel images for the FreeType 1.x driver.
736 http://rt.cpan.org/Ticket/Display.html?id=11972
738 - fix rendering on alpha channel images for the T1lib driver.
739 http://rt.cpan.org/Ticket/Display.html?id=11972
741 - reworked library probing, we can now set more than one probe
742 function for a library. Disabled the default (non-freetype-config)
743 library probe and added an extra probe function that searches for
744 both ft2build.h and whatever it includes, and adds -I as needed.
745 Hopefully this will fix build problems like

747 http://rt.cpan.org/Ticket/Display.html?id=26086
749 Imager 0.57 - 30 Apr 2007
752 This is a maintenence release fixing a security issue in Imager.
754 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
755 overflow in malloced memory. There will be further discussion of
756 this issue in the ticket below.
757 http://rt.cpan.org/Ticket/Display.html?id=26811
758 CVE-2007-2459 CVE-2007-2413
759 The descriptions at cve.mitre.org varied in quality, please see the
760 ticket at rt.cpan.org for a more accurate description of the issue.
762 Imager 0.56 - 1 Apr 2007
765 - added support for reading 16-bit/sample PGM/PPM images
767 - added support for writing 16-bit/sample PGM/PPM images
769 - improved performance of reading PBM/PGM/PPM images
771 - added support for writing PBM images if the image is paletted and
772 contains only black and white
774 - added a new make_colors value - "mono"
776 - switched from the svn log Changes to a manual Changes to reduce
779 - new sample code - samples/flasher.pl
783 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
784 was returning an image object with an extra reference, this
785 resulted in a memory leak.
786 http://rt.cpan.org/Ticket/Display.html?id=24992
788 - fix rendering on alpha channel images for the FreeType 2.x driver
789 http://rt.cpan.org/Ticket/Display.html?id=11972
791 - reading bmp files now consitently handles short reads. You can now
792 supply a parameter to treat a short read as successful and set
794 http://rt.cpan.org/Ticket/Display.html?id=8426
796 - previously, reading ASCII PBM files required spaces between samples,
797 even though the format doesn't require that
799 - improved documentation of the unsharpmask filter (I hope)
800 http://rt.cpan.org/Ticket/Display.html?id=25531
802 - force flushing of the output from i_tt_dump_names() and test output
803 in t/t35ttfont.t to prevent output from being mixed up.
804 https://rt.cpan.org/Ticket/Display.html?id=24859
806 - rewrite a conditional expression as an if() to hopefully work around
807 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
808 https://rt.cpan.org/Ticket/Display.html?id=25561
810 - avoid Data::Dumper in regops.perl to support older releases of perl
811 https://rt.cpan.org/Ticket/Display.html?id=24391
813 Imager 0.55 - 16 Dec 2006
816 This is primarily a bug fix release.
818 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
820 There is one new feature:
822 - the Win32 font driver now supports UTF8 (RT 22166)
823 http://www.cpanforum.com/threads/3276
824 http://rt.cpan.org/Ticket/Display.html?id=22166
826 Several bugs were fixed:
828 - the string() method would not output the string "0"
829 http://rt.cpan.org/Public/Bug/Display.html?id=21770
831 - fills.c was failing to compile on Solaris 10 (compiler unknown)
832 http://rt.cpan.org/Public/Bug/Display.html?id=21944
834 - the gif_disposal and gif_user_input tags weren't being read from
836 http://rt.cpan.org/Public/Bug/Display.html?id=22192
838 - gif.c was failing to build under MSVC
839 http://rt.cpan.org/Ticket/Display.html?id=23922
841 - in some cases strings passed to the string() method were treated as
842 terminated by NUL (chr 0)
843 http://rt.cpan.org/Public/Bug/Display.html?id=21770
845 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
846 that's the default build name for zlib on Win32.
847 http://rt.cpan.org/Ticket/Display.html?id=23064
849 - search $Config{incpath} for headers too, which we should have been
852 Win32 font driver fixes:
854 - the global descent value from bounding box was the wrong sign
855 http://www.cpanforum.com/threads/3276
857 - if the first or last glyph overflowed the left or right side of the
858 advance width they would be clipped
861 Imager 0.54 - 14 Sep 2006
864 This is primarily a feature release:
866 - a new qtype value 'mixing' has been added to the scale()
867 method. This is faster than 'normal', slower than 'preview'. This
868 is based on the method used by pnmscale, and seems to produce less
869 blurry results than normal.
870 http://rt.cpan.org/Public/Bug/Display.html?id=20677
872 - the rubthrough() method can now render onto images with an alpha
874 http://rt.cpan.org/Ticket/Display.html?id=20678
876 - the read_multi() method now falls back to calling doing a single
877 image read via the read() method and write_multi() will now fall
878 back to calling write() if a single image is supplied. This means
879 you can simply call the read_multi() or write_multi() functions
880 without having to check if the type is formatted by that method.
881 http://rt.cpan.org/Ticket/Display.html?id=19457
882 http://rt.cpan.org/Ticket/Display.html?id=19458
884 - the GIF loop extension can now be written. If you don't have
885 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
887 http://rt.cpan.org/Ticket/Display.html?id=21185
889 - getscanline() and setscanline() can now read/write palette index
890 based data from/to the image for paletted images, by setting type to
892 http://rt.cpan.org/Ticket/Display.html?id=20338
894 - we no longer hassle you to disable GIF support
895 http://rt.cpan.org/Ticket/Display.html?id=20687
897 - minor documentation fixes
900 Imager 0.53 - 26 Jul 2006
903 This is a bugfix release.
905 Some test code was left in a code path not covered by the test
906 suite. A test was added to cover this code path and the test code was
908 http://rt.cpan.org/Public/Bug/Display.html?id=20705
911 Imager 0.52 - 25 Jul 2006
914 This is primarily a feature release, but contains a fair few bug
917 - ability to read and write MS Windows ICO and CUR files
919 - you can now add file format plugins to support new file formats
921 - add POD coverage tests
923 - setcolors() and addcolors() now accept color names and so on
924 instead of requiring Imager::Color objects.
925 http://rt.cpan.org/Ticket/Display.html?id=20056
927 - flood_fill() can now fill to a specified border color instead of
928 just to the area the same color as the seed.
929 http://rt.cpan.org/Ticket/Display.html?id=19618
934 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
935 calculating the advance width.
936 http://rt.cpan.org/Public/Bug/Display.html?id=20554
938 - bounding_box for the T1 driver wasn't including leading and
939 trailing spaces in the bounding box as the other drivers did, it also
940 produced strange results for empty strings or strings containing only
943 - when reading CMYK jpeg images they were being transferred to the
944 image object as is, producing a four channel image. It only looked ok
945 due to an old still unfixed Photoshop bug. We now convert from the
946 inverted CMYK that photoshop (and Corel for example) produce into RGB.
947 http://rt.cpan.org/Ticket/Display.html?id=20416
949 - reading a CYMK TIFF would result in a 4 channel image, reading any
950 image with more than 4 channels (eg. RGB with 2 alpha channels) would
952 http://rt.cpan.org/Ticket/Display.html?id=20415
954 - added /usr/local/include to the default include search path, since
955 we were already searching /usr/local/lib for libraries.
957 And various minor fixes and documentation updates.
960 Imager 0.51 - 23 Apr 2006
963 - fix a validation bug when processing JPEG EXIF data that can cause
965 http://rt.cpan.org/Public/Bug/Display.html?id=18496
967 - fix mis-processing of the src_maxx and src_maxy parameters of the
969 http://rt.cpan.org/Public/Bug/Display.html?id=18712
971 - fix a problem in Imager's "smart" handling of the color parameter
973 http://rt.cpan.org/Public/Bug/Display.html?id=18561
976 Imager 0.50 - 29 Mar 2006
979 - CRITICAL: fixes a segmentation fault from attempting to write a 2
980 or 4 channel image to jpeg or a 2 channel image to tga where the
981 output is an in-memeory buffer.
982 http://rt.cpan.org/Public/Bug/Display.html?id=18397
984 - fixes an incorrect pointer parameter in the PNG code
985 http://rt.cpan.org/Public/Bug/Display.html?id=18051
987 - skip Inline::C tests when building in a directory with spaces
