1 Imager release history. Older releases can be found in Changes.old
3 - re-work the t/200-file/400-basic.t to correctly handle failures
4 It's custom ok() function didn't have a prototype and didn't use scalar().
5 This caused ok() to use the note instead of the value being tested when
6 the method called returned an empty list. For an example of the problem
7 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
9 - remove some noise from when Imager tried to work with buggy
12 - the new autolevels filter (Imager 0.99) used an integer for the
13 sample scaling factor which caused the top output level to be too
14 low (depending on the scaling required.) It now uses a double.
15 https://rt.cpan.org/Ticket/Display.html?id=111871
17 - the new autolevels filter had off-by-one errors calculating the
18 minimum and maximum luminance from the histogram. This slightly
19 reduced the contrast of the output image.
20 https://rt.cpan.org/Ticket/Display.html?id=111871
22 - the new autolevels filter now uses a lookup table for 8-bit images
23 to avoid a floating point multiply for each sample.
24 https://rt.cpan.org/Ticket/Display.html?id=111871
26 - fixed several memory leaks detected by valgrind:
28 - addcolors() leaked the temporary array of colors supplied to the
31 - make_palette() leaked the temporary image array (not the images
32 themselves) passed to the internal API.
34 - combine()/i_combine() leaked its working row buffers
36 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
37 buffer if there were too many colors
39 - getcolorcount()/i_count_colors() leaked the sample buffer if
40 there were too many colors.
42 - the nearest_color filter (undocumented until I find a use for it)
43 leaked both temporaries passed to the API and internal buffers
45 - fixed some uninitialized memory usage detected by valgrind:
47 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
48 i_matrix_transform_bg() didn't initialize a working color value
49 if there was zero pixel coverage.
51 - i_ft2_cp() didn't initialize the complete color when producing an
52 intermediate image. This caused uninitialized value usage when
55 Imager 1.004 - 8 Nov 2015
58 - Imager::Color::Table is now pre-loaded by the preload() method.
59 https://rt.cpan.org/Ticket/Display.html?id=104896
61 - fix an assertion triggered under perl 5.23.4.
62 Thanks to A. Sinan Unur for the report and the patch.
64 - Imager->new can now be used to read raw image files.
65 https://rt.cpan.org/Ticket/Display.html?id=106836
66 Thanks to Richard Kelsch for reporting this.
68 - deal with output changes from Pod::Spell
69 https://github.com/perl-pod/Pod-Spell/issues/21
71 Imager 1.003 - 12 May 2015
74 - update 1.002 release notes to include the center change for filled
77 - flood_fill() would escape beyond a 4-connected space under some
79 Added many more flood_fill() tests.
80 https://rt.cpan.org/Ticket/Display.html?id=103786
82 Imager 1.002 - 3 Apr 2015
85 - drawing anti-aliased filled circles is now 10 to 50 times faster
86 depending on the size of the circle.
87 This also changed the center from being the center of the pixel to
88 being the top left of the pixel to match the filled arcs drawn by
90 https://rt.cpan.org/Ticket/Display.html?id=101682
92 - enhancements to polygon filling:
94 - added a mode parameter to control how overlapping regions behave
96 - added a polypolygon() method to fill more than one polygon at a
99 - polygon filling is now exposed through the API.
101 - added colormodel(), alphachannel() and colorchannels() methods.
102 These were added for two reasons:
104 - a future version of Imager may allow the number of channels in
105 an image to not directly represent the color model of an image.
106 eg. a greyscale TIFF image with multiple alpha channels.
108 - a future version of Imager may allow an image to be read without
109 translation, for example a TIFF file that contains measurements
110 from an instrument. Currently Imager transforms the samples into
111 the range 0.0 ... 1.0 which may means the user has to translates
114 An untranslated image would be unusable as image data, so
115 colormodel() would return "unknown" in this case.
117 Similarly a CMYK image might be returned as an "unknown" color
118 model image, if the caller chooses to disable translation to
121 Imager 1.001 - 2 Jan 2015
124 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
125 Thanks to Slaven Rezic for the report and the patch.
126 https://rt.cpan.org/Public/Bug/Display.html?id=98234
128 - GIF: clean-up a test file if the test for the giflib 4.2.0 file
131 - fix Imager::Matrix2d::rotate()'s centre point handling
132 https://rt.cpan.org/Public/Bug/Display.html?id=99959
134 - ICO: don't apply the icon mask to images with an alpha channel by
136 https://rt.cpan.org/Public/Bug/Display.html?id=99507
138 - make verbose probing output more verbose
140 - use Imager::Probe to probe for freetype 1.x
141 https://rt.cpan.org/Ticket/Display.html?id=100502
143 - The --enable and --disable parameters to the top-level Makefile.PL
146 - update the bundled/modified Devel::CheckLib to handle the gcc-4
149 Imager 1.000 - 28 Jul 2014
152 There's nothing special about Imager 1.000, it's just another release.
154 - fix the skip check for the iolayer qr// buffer test
156 - improve error reporting for the iolayer test failing on a small
157 number of Win32 CPAN testers
159 Imager 0.99_02 - 21 Jul 2014
162 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
163 the blue channel in the generated palette, and allow each color
164 component to be in the range 100..255 instead of just 100..254.
165 Thanks to Ralf Neubauer.
166 https://rt.cpan.org/Ticket/Display.html?id=97086
168 - revert "improved the XS for i_io_read() and i_io_raw_read()"
169 This caused problems with older perls and didn't provide much of a
170 performance improvement.
172 - support Inline 0.57 and later.
173 Inline 0.57 changed the "with" interface.
174 https://rt.cpan.org/Ticket/Display.html?id=97108
176 - don't define our own MAXINT macro, it conflicts with windows header
177 files and in a few places it was the wrong value to use anyway.
178 https://rt.cpan.org/Ticket/Display.html?id=96425
180 Imager 0.99_01 - 29 Jun 2014
183 - GIF: add support for giflib 5.1.0, which added error code pointer
184 parameters to EGifCloseFile() and DGifCloseFile().
185 https://rt.cpan.org/Ticket/Display.html?id=96756
187 - GIF: avoid a double-free when do_write() fails.
189 - fix SV type probing to work on perl before 5.12. Broken in 0.99.
190 https://rt.cpan.org/Ticket/Display.html?id=96761
192 - PNG: skip the benign error test before libpng 1.6.0, since the
193 error we're testing didn't exist before 1.6.0.
194 https://rt.cpan.org/Ticket/Display.html?id=94717 (continued)
196 Imager 0.99 - 25 Jun 2014
199 - Imager::IO->new_buffer() (and hence Imager->read()'s data
200 parameter) now accepts a reference to a scalar as well as just a
202 https://rt.cpan.org/Ticket/Display.html?id=92785
204 - Imager::IO->new_buffer() now always makes a copy of the passed in
205 buffer to avoid problems with temporary objects used for the return
207 https://rt.cpan.org/Ticket/Display.html?id=92785
209 - improved the XS for i_io_read() and i_io_raw_read()
210 https://rt.cpan.org/Ticket/Display.html?id=92738
212 - load plugins from absolute paths on Android
213 Thanks to Brian Fraser.
214 https://rt.cpan.org/Ticket/Display.html?id=93272
216 - added the jpeg_optimize parameter for writing JPEG files. This can
217 significantly reduce file sizes, but uses more memory and time.
218 https://rt.cpan.org/Ticket/Display.html?id=94292
220 - the autolevels filter now works on the luminosity of the image
221 rather then working per channel. The old autolevels filter is
222 still available as "autolevels_skew".
223 https://rt.cpan.org/Ticket/Display.html?id=94413
225 - Imager::File::PNG now supports libpng 1.6.10.
226 1.6.10 changed CRC errors from benign errors to normal errors,
227 which broke the test which used CRC errors to check for benign
228 error support. Switched to using a 1-bit grey-scale image with a
229 palette to test for benign errors.
230 https://rt.cpan.org/Ticket/Display.html?id=94717
232 Imager 0.98 - 3 Jan 2014
235 Incompatible changes:
237 - the return value of setpixel() has changed.
239 Previously the return values for undrawable pixels vs caller errors
240 changed depending on whether you used the multiple pixel calling
241 mechanism, or the single pixel mechanism.
245 - for an invalid parameter, such as an unknown colour, or missing
246 parameter, an empty list (or undef in scalar context) is
247 returned, and errstr() is set,
249 - otherwise the number of pixels drawn is returned. If none of
250 the pixels could be drawn (they were all outside the image), "0
251 but true" is returned.
253 https://rt.cpan.org/Ticket/Display.html?id=87650
257 - when drawing on an image with an alpha channel where the source
258 minimum is greater than zero, Imager would read from beyond the end
259 of a malloc() allocated buffer. In rare circumstances this could
260 lead to some of the source image not being written to the target
261 image, or possibly to a segmentation fault.
262 I don't believe this has any security concerns beyond that.
264 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
265 text drawn would be nonsense. This would also read beyond the end
266 of a malloced buffer.
268 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
270 https://rt.cpan.org/Ticket/Display.html?id=88993
272 - Imager::Font::Wrap no longer requires the image parameter.
273 https://rt.cpan.org/Ticket/Display.html?id=87338
275 - a documentation typo fix in Imager::Transformations
276 Thanks to Adrian Yee.
277 https://rt.cpan.org/Ticket/Display.html?id=88598
279 - Image::Probe, Imager's internal module for probing library
280 locations now searches the directories specified by LD_RUN_PATH,
281 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
282 and the corresponing s/\blib$/include/ directories for header
284 https://rt.cpan.org/Ticket/Display.html?id=86428
286 Imager 0.97 - 15 Jul 2013
289 No changes from 0.96_02.
291 Imager 0.96_02 - 8 Jul 2013
294 - PNG: treat a version mismatch between headers and library as a
296 https://rt.cpan.org/Ticket/Display.html?id=86659
298 - PNG: the check for benign error support is more complex than a
299 simple library version check, check for the appropriate macro.
300 Thanks for Slaven Rezic for following up on my CPAN Testers result
302 https://rt.cpan.org/Ticket/Display.html?id=86659
304 - W32: add a missing head1 AUTHORS to the old Win32.pm
305 https://rt.cpan.org/Ticket/Display.html?id=86658
307 Imager 0.96_01 - 1 Jul 2013
310 - TIFF: handle SampleFormat = 2 by translating the signed integer
311 values to unsigned by flipping their sign bits.
313 Handle SampleFormat = 3 where possible.
315 SampleFormat is ignored for paletted images.
317 Mixed SampleFormat are handled incorrectly, since libtiff returns
318 only the first SampleFormat value, and an image with both an alpha
319 channel and SampleFormat = 2 for color channels probably has a
320 different SampleFormat for the alpha channel.
322 https://rt.cpan.org/Ticket/Display.html?id=74540
325 https://rt.cpan.org/Ticket/Display.html?id=69243
327 - Imager::Color's rgba() method now returns its values as integers
328 instead of floating point. (IV instead of NV).
330 - The XS for i_map() and i_matrix_transform() now use the AV *
331 typemap instead of rolling their own.
333 - The XS for DSO_call() now uses the HV * typemap instead of
336 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
337 i_gradgen() now use a new T_AVARRAY typemap that greatly
338 simplifies the XS code.
340 - many other minor XS changes
342 - some XS code formatting
344 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
345 now renders in alpha-combining mode, to match antialiased output.
346 https://rt.cpan.org/Ticket/Display.html?id=73359
348 - add sample code and cookbook notes for drawing a blurred drop-shadow.
350 - add support for libpng 1.6, which changed the defaults for
351 reporting some types of error.
352 https://rt.cpan.org/Ticket/Display.html?id=85746
354 - FT2: use gsamp/psamp() to transfer pixels from the work image to
355 the output image instead of gpix/ppix.
356 https://rt.cpan.org/Ticket/Display.html?id=83478
358 - eliminate various GCC warnings, mostly initialized but otherwise
361 Imager 0.96 - 19 May 2013
364 - rearrange Imager's test files.
365 https://rt.cpan.org/Ticket/Display.html?id=84596
367 - Imager::Probe::_gcc_lib_paths now forces C locale.
368 A sufficiently recent gcc prints localized keys for the search
369 paths, which avoids that localization.
370 https://rt.cpan.org/Ticket/Display.html?id=84963
372 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
373 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
375 https://rt.cpan.org/Ticket/Display.html?id=85262
376 reported by Andreas König
378 - add a test for unclosed POD in C source, and fix the errors it
380 https://rt.cpan.org/Ticket/Display.html?id=74875
382 - fix some spelling errors detected by the newer aspell in Debian
385 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
386 thanks to gregor herrmann <gregoa@debian.org>
387 https://rt.cpan.org/Ticket/Display.html?id=85413
389 - add a test for standard =head1 commands and fix the errors found
391 Imager 0.95 - 19 Apr 2013
394 - handle the SVf_UTF8 flag correctly on magic strings passed to
395 Imager::IO's write() and raw_write() methods.
396 This may misbehave in perl 5.6.x since the UTF8 flag may not be
397 visible in the main SV after SvGETMAGIC().
398 https://rt.cpan.org/Ticket/Display.html?id=83438
400 - document that bounding_box() ignores the transformation matrix
401 supplied to tranform() for fonts.
402 https://rt.cpan.org/Ticket/Display.html?id=84106
404 Imager 0.94_02 - 5 Apr 2013
407 - enable debug logging for the standard font tests
409 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
410 due to a bug in that version of perl.
412 - don't test for read() failing on a write-only handle in 5.8.x and
413 earlier, this was fixed in change 862083f7e4 in perl.
415 - report the version of Inline found during testing (an attempt to
416 diagnose some intermittent failures.)
418 Imager 0.94_01 - 2 Mar 2013
421 - NOTE: possibly backward incompatible:
422 support reading from/writing to perl filehandes that aren't raw
425 This allows Imager's I/O to honour handles with layers such as
426 gzip, scalar file handles or tied file handles.
428 This is backward incompatible in that previous Imager would simply
429 use fileno() to retrieve the fd for the file and call write(2) etc
431 https://rt.cpan.org/Ticket/Display.html?id=78843
433 - moved most of README to lib/Imager/Install.pod which should make it
434 more accessible to the "web" generation, also significantly updated
437 - updated README's for the separately distributed modules to refer to
438 Imager::Install, and that they need -dev versions of packages
439 https://rt.cpan.org/Ticket/Display.html?id=81265
441 - the JPEG test code now reports the compile-time library version
443 - avoid a possible compiler optimization issue on CentOS 5.9 i386 by
444 rearranging (and mildly optimizing) some code.
445 https://rt.cpan.org/Ticket/Display.html?id=83212
447 - fix a POD error in Imager::Fill (detected on new Pod-Simple)
448 https://rt.cpan.org/Ticket/Display.html?id=83434
450 - fix a broken link to Graphics::Magick
451 https://rt.cpan.org/Ticket/Display.html?id=82743
453 - drawing text to a channel with FT2 would draw with random coverage
454 due to an uninitialized alpha channel.
456 - marked the function pointer underlying the mm_log() API with the
457 correct gcc magic and fixed the resulting warnings.
459 - fixed some other compiler warnings
461 - Imager::Font::W32 now properly reports text drawing errors
462 https://rt.cpan.org/Ticket/Display.html?id=70098
464 - handle the SVf_UTF8 flag correctly on magic (eg. overloaded)
465 strings passed as text to draw(), bounding_box(), has_chars(),
466 glyph_names() (where supported) in each of the font drivers.
467 This may misbehave in perl 5.6.x since the UTF8 flag may not be
468 visible in the main SV after SvGETMAGIC().
469 https://rt.cpan.org/Ticket/Display.html?id=83438 (partial)
471 Imager 0.94 - 15 Dec 2012
472 =========================
474 Variations on some of these changes were included in development
477 - improved thread safety
478 - the internal error stack and log file handle are now in a per-thread
480 - JPEG now captures IPTC information in a thread-safe way
481 - avoid globals where possible for warning capture in libtiff
482 - use a mutex to avoid re-entering thread-unsafe giflib
483 - use a mutex to avoid re-entering thread-unsafe tifflib
484 - use a mutex to avoid re-entering thread-unsafe T1Lib
485 - use a library handle per thread for freetype 2.
486 - use an engine handle per thread for freetype 1.x.
487 - originally these changes broke ABI compatibility, this has been
490 - clarify the return value of getpixel();
491 https://rt.cpan.org/Ticket/Display.html?id=81198
493 - fixed a race condition in parallel testing for T1
495 - fixed a bug in handling yoff for untransformed image-based fills
497 - documentation improvements for Imager::Fill
499 - FT2: report the library version while testing.
501 Imager 0.93 - 15 Oct 2012
506 - previously a transparency enabled GIF write (the default) would
507 always use a GIF89a header even if none of the images were
510 - previously the probe step for freetype-config would fail on cygwin
512 - catch an invalid matrix parameter to convert() instead of crashing
513 https://rt.cpan.org/Ticket/Display.html?id=79922
515 - remove the 16-bit/sample limitation from the documentation for
516 setsamples(), it hasn't applied for many releases.
517 https://rt.cpan.org/Ticket/Display.html?id=79989
519 - don't copy setsamples() data parameter, it may be a large scalar
520 https://rt.cpan.org/Ticket/Display.html?id=79990
522 - clean up .dSYM directories generated performing probes on OS X
525 - pass the --verbose command-line option through to Imager::Probe in
526 sub-module's Makefile.PLs
527 https://rt.cpan.org/Ticket/Display.html?id=75878
531 - support for giflib 5.0. (5.0.1 and later)
532 https://rt.cpan.org/Ticket/Display.html?id=79029
533 The giflib API Imager uses doesn't have a mechanism to set the
534 header version in 5.0.0.
536 - update the GIF library probe code to check for the new giflib 5.0.1
537 EGifSetGifVersion() function, and to check for the giflib 4.2.0
538 uninitialized gif89 bug.
539 https://rt.cpan.org/Ticket/Display.html?id=79679
540 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
542 - avoid static variables when capturing IPTC data from JPEG files
544 - match Imager::Font;:T1's error message translations to those from
545 later versions of T1Lib.
547 - for libtiff versions that support extended warning handlers (3.8.0
548 or later), use them to avoid some global variables.
550 - note Image::ExifTool for better metadata support.
551 https://rt.cpan.org/Ticket/Display.html?id=79251
553 Imager 0.92 - 14 Aug 2012
556 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
557 correctly for both probing and runtime.
558 https://rt.cpan.org/Ticket/Display.html?id=77672
560 - allow building JPEG/imexif.c on C89 compilers.
562 - allow building GIF/imgif.c on C89 compilers.
564 Imager 0.91 - 4 Jun 2012
569 - The size of rotated images is no longer rounded up so aggressively.
570 Added rounding to the linear interpolation done for rotate() and
571 matrix_transform() for 1 and 3 channel 8-bit images.
572 Adjusted the two tranlate matrices used to build the final rotation
573 matrix to use the distance between the outlier pixels rather than
574 the pixel dimensions (ie. dimension-1).
575 With all of this the output of rotate(degrees => 270) on an 8-bit
576 image exactly matches the output of rotate(right => 270).
577 https://rt.cpan.org/Ticket/Display.html?id=77063
581 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
582 internals, those names only matter for the XS interface.
584 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
585 the API level compiled into a loadable module such as
586 Imager::File::GIF doesn't match that of Imager. Previously it
587 could be difficult to determine exactly which module was failing to
589 https://rt.cpan.org/Ticket/Display.html?id=77173
591 - added Imager->check_file_limits() as an interface to the
592 i_int_check_image_file_limits() API.
594 - Imager->set_file_limits(reset => 1) now resets the limits to the
595 defaults rather than setting them all to unlimited.
597 - wrote a brief security note as Imager::Security
598 https://rt.cpan.org/Ticket/Display.html?id=68910
600 Imager 0.90 - 30 Apr 2012
605 - Imager::Test::is_imaged() attempted to process an "epsilon"
606 parameter but the prototype didn't allow for the extra parameter.
607 Corrected the prototype.
609 - when downconverting samples (eg. from floating point to 8 bit)
610 Imager now rounds the sample value rather than attempting to
611 allocate input values over output values equally. The old
612 behaviour had the probably surprising effect of converting a
613 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
615 This may result in slightly different 8 or 16-bit output images.
617 - BI_BITFIELD BMP images were handled incorrectly, both in
618 incorrectly calculating the space required for the masks and in
619 processing the image data itself.
620 https://rt.cpan.org/Ticket/Display.html?id=76736
622 - some odd width BMP BI_RLE4 images use run lengths that run one off
623 the edge of the image. Imager now allows this, discarding the
626 - odd length RLE4 runs in BMP images were decoded incorrectly.
628 - pkg-config could sometimes return a library that was in a directory
629 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
630 If no -L is included in the pkg-config library information check if
631 EU::MM can find the library, and if not, search our configured
632 directories and insert that into the library flags.
633 https://rt.cpan.org/Ticket/Display.html?id=75869
635 - Imager::Probe can now probe for libraries with dependent libraries,
636 common for static linking, eg. libpng requires libz.
637 https://rt.cpan.org/Ticket/Display.html?id=74043
639 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
641 - added alternative probe configurations that try to link libz, to
642 handle a statically linked libpng.
643 https://rt.cpan.org/Ticket/Display.html?id=74043
645 - if a probe includes testcode, Imager::Probe now checks that code as
646 part of the process of checking each configuration rather than as a
647 post test of the found configuration. This allows alternate
648 configurations to be checked if a matching but non-working
649 configuration is found.
650 https://rt.cpan.org/Ticket/Display.html?id=74043
654 - when reading or writing images via callbacks, the default callbacks
655 now push an error message indicating that a required callback was
656 called but not supplied.
657 https://rt.cpan.org/Ticket/Display.html?id=76782
659 - clarify which callbacks are required for reading and writing TIFF
662 - improve logging for creation of callback I/O layers.
664 - a little more documentation for Imager::Probe.
666 - the i_get_file_background() and i_get_file_backgroundf() APIs now
667 return int to indicate whether the i_background tag was found.
670 - improve error reporting
671 - add png_interlace, png_bits tags
672 - read paletted images as paletted images, including transparency
673 - read 1 bit greyscale images as a type suitable for other file
674 handlers to write as bilevel
675 - read 16 bit/sample PNG as 16-bit/sample Imager images
676 - write "bilevel" paletted images as 1 bit grayscale images
677 - write paletted images as paletted images
678 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
680 - improved metadata support
681 https://rt.cpan.org/Ticket/Display.html?id=29268
683 Imager 0.89 - 18 Mar 2012
688 - getpixel(..., type => "float") and the API i_gpixf() have been
689 broken on paletted images since they were implemented.
690 https://rt.cpan.org/Ticket/Display.html?id=75258
694 - links in the METHOD INDEX now point at the method documentation
695 rather than the heading you can find them under.
696 https://rt.cpan.org/Ticket/Display.html?id=71495
698 - Imager (and the bundled dynamic modules) no longer fallback to
699 using DynaLoader if loading via XSLoader fails.
700 For the bundled modules this could hide useful error messages.
701 https://rt.cpan.org/Ticket/Display.html?id=75560
703 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
704 buffer in the array of allocations, but just stores the filename
705 pointer and line number.
706 https://rt.cpan.org/Ticket/Display.html?id=70388
708 Imager 0.88 - 22 Feb 2012
711 - describe how to build libgif etc on OS X in such a way as to be
712 compatible with a fat binary perl (such as the system perl), in
714 https://rt.cpan.org/Ticket/Display.html?id=73371
716 - update the change notes for 0.77_01 to indicate that libungif
719 - add some other imaging modules to SEE ALSO
720 https://rt.cpan.org/Ticket/Display.html?id=73906
722 - note that the generator of the apparently non-DFSG-free postscript
723 in MMOne.pfb is a Debian package.
725 - setsamples() is now a true complement to getsamples() - it can
726 write 8-bit or floating point samples from a scalar or array
727 reference. This adds i_psamp() and i_psampf() to the C level API.
729 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
730 changed to make better use of the typemap, but these aren't part of
731 the perl level API anyway. There were no changes to the C level
732 interfaces to these functions.
734 - getpixel() and setpixel() now accept a mix of scalar and array
735 references for the x and y parameters, and unequal array lengths is
737 https://rt.cpan.org/Ticket/Display.html?id=73697
741 - correctly calculate the size of a rotated image
742 https://rt.cpan.org/Ticket/Display.html?id=69261
744 - fix incorrect rounding of color values for matrix_transform() and
746 https://rt.cpan.org/Ticket/Display.html?id=69261
748 - Win32 text output is now done in normal combine mode, the alpha
749 component of the color is now significant.
750 https://rt.cpan.org/Ticket/Display.html?id=70014
752 - remove long unused gif case from read()
753 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
755 - the getsamples() target parameter was being treated as a hashref
756 when it's meant to be an array reference.
757 https://rt.cpan.org/Ticket/Display.html?id=74882
759 - getpixel() and setpixel() now returns an empty list when invalid
760 parameters are supplied.
761 Invalid values for type now result in an error for getpixel().
762 https://rt.cpan.org/Ticket/Display.html?id=73697
764 Imager 0.87 - 03 Jan 2012
767 - document the return value of the filter() method.
768 https://rt.cpan.org/Ticket/Display.html?id=72369
770 - document i_gsamp_bits() and i_psamp_bits().
771 https://rt.cpan.org/Ticket/Display.html?id=68815
773 - properly increment the Imager::Matrix2d $VERSION.
775 - actually include the Imager::Test tests in the dist
777 - correctly read and write 256x256 pixel ICO files
778 https://rt.cpan.org/Ticket/Display.html?id=69599
780 - make the error message from read() or read_multi() when they can't
781 identify the file type match reality.
782 https://rt.cpan.org/Ticket/Display.html?id=72475
784 - read() now uses $FORMATGUESS if it can't determine the file type
785 based on the file header, to match read_multi().
787 - re-work and add tests for def_guess_type(). def_guess_type() no
788 longer returns any random file extension as the file type.
790 - add gray4, gray16 and gray as presets for make_colors.
791 https://rt.cpan.org/Ticket/Display.html?id=67911
793 - add make_palette() method that produces a palette from one or more
796 - fix the Imager dependency for the separately distributed font
798 https://rt.cpan.org/Ticket/Display.html?id=72643
800 - fix i_render_color() to properly draw in "normal" mode - ie. when
801 writing to a 1 or 3 channel image the second or fourth channel of
802 the source color was being ignored, it is now significant.
803 https://rt.cpan.org/Ticket/Display.html?id=71564
805 Imager 0.86 - 31 Oct 2011
808 - improve error reporting for W32 tests
810 Imager 0.85_02 - 24 Oct 2011
815 - eliminate unused i_gif_opts type (clean-up)
816 https://rt.cpan.org/Ticket/Display.html?id=69245
818 - fix combine=0 fill color anti-aliasing on the double/sample path
819 https://rt.cpan.org/Ticket/Display.html?id=71309
821 - make default text color non-transparent
822 https://rt.cpan.org/Ticket/Display.html?id=71469
824 - apply the last of the Debian unforwarded spelling fixes
825 https://rt.cpan.org/Ticket/Display.html?id=70656
827 - the log() method used its message parameter as a C level format
829 https://rt.cpan.org/Ticket/Display.html?id=71653
831 - provide our own STRLEN typemap entry for older perls.
832 https://rt.cpan.org/Ticket/Display.html?id=71641
834 - add extra ppport.h configuration to support older perls.
836 - depend on Scalar::Util, since we use it and older perls don't have
839 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
840 to synthesize it from overloaded "".
842 - use T1_StrError() for error messages on modern libt1
843 https://rt.cpan.org/Ticket/Display.html?id=69879
845 - actually load the font rather than just adding it to the catalog on
848 - Imager::Font->new now produces better error messages for the T1
851 - the font has_chars() method now returns perl's true and false
852 values in list context rather than integers, which should be more
854 https://rt.cpan.org/Ticket/Display.html?id=69158
856 - the btm data structure used by the flood_fill code is now
857 initialized more efficiently.
858 https://rt.cpan.org/Ticket/Display.html?id=68994
860 - updated the Thanks list in README
861 https://rt.cpan.org/Ticket/Display.html?id=71607
863 - check there's at least one coefficient for the convolution filter
864 https://rt.cpan.org/Ticket/Display.html?id=68993
866 - make the APIRef synopsis ordering consistent, older versions of
867 perl could order it differently.
868 https://rt.cpan.org/Ticket/Display.html?id=71675
870 - we rely on Config.pm's d_vsnprintf as to whether we use
871 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
872 though it only has _ prefixed versions of these. Define our own
873 prefixed names on Win32.
874 https://rt.cpan.org/Ticket/Display.html?id=71642
876 - fix library detection with MSVC
878 - search a few more library directories, so EU::MM doesn't discard
879 them. Hopefully fixes:
880 https://rt.cpan.org/Ticket/Display.html?id=71643
882 Imager 0.85_01 - 10 Oct 2011
885 - add simple tests for the Imager::Test test_image generators
887 - io_glue I/O buffering re-work:
889 - reorganize io_glue to do it's own buffering by default
891 - the unbuffered functions are available as i_io_raw_read() (or
892 raw_read() from perl) etc but are not recommended for typical
895 - use the new i_io_peekn() when checking for file magic to avoid
896 seek, allowing Imager to detect the file type and read the file
897 from an unseekable stream (for formats that don't use random
900 - added several new I/O layer API functions.
902 - fix the TGA performance problem, most noticably on Win32
903 https://rt.cpan.org/Ticket/Display.html?id=70037
905 - TIFF now uses wrapper functions of the correct types to avoid casts
906 https://rt.cpan.org/Ticket/Display.html?id=69912
908 - the callback IO object did its own buffering, controlled by the
909 maxbuffer parameter supplied to the read() and write() methods.
910 This buffering has been removed, to avoid redundancy with the
911 common io_glue buffering. This also avoids a bug in that code
912 which could rarely pass a zero length to the read callback and
913 then panic about the result.
915 - the callback IO object now tests the result of calling the close
916 callback, which should return true for success.
918 - the PNM reader did its own buffering. This buffering has been
919 removed to avoid redundancy with the common io_glue buffering.
921 - previously the read handlers for fd and callback I/O layers would
922 call the underlying interface (POSIX read or your supplied callback)
923 until it filled the buffer. It now only makes one call.
925 - added public constructors for I/O layer objects (see Imager::IO)
927 - all core file handlers now use the i_io_foo() wrappers to gain
928 access to buffered I/O rather than calling the I/O layer
931 - all core file handlers now check for error on close.
933 - Backward compatibility: if you hava custom file handlers, you can
934 use i_io_write() etc since they're available as macros in older
937 - eliminate the final remnants of io_glue_commit_types().
939 - bump IMAGER_API_VERSION, since the above may break assumptions.
941 - removed the long unused i_gen_reader() and i_gen_writer() utility
944 Imager 0.85 - 29 Aug 2011
947 The main changes in the release versus 0.84 are:
949 - on 64-bit systems, 64-bit types are consistently used for image
950 dimensions and co-ordinated, and for memory block sizes.
952 - handle IFD loops in TIFF files correctly. Previously this would
953 lead to an infinite loop.
957 - fix the link in the getheight() entry in the method index
959 Imager 0.84_02 - 22 Aug 2011
962 Development release, this will become 0.85 if CPAN testers is
967 - the image file limits set by set_file_limits() weren't being
968 checked when reading TIFF files.
969 https://rt.cpan.org/Ticket/Display.html?id=69915
971 - Provide more information about file format module load errors on a
972 failed image file read() or write().
973 https://rt.cpan.org/Ticket/Display.html?id=69194
975 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
976 through TIFF images, since it checks for IFD loops.
977 https://rt.cpan.org/Ticket/Display.html?id=69914
979 - don't leak memory when out of range palette indexes are supplied to
981 https://rt.cpan.org/Ticket/Display.html?id=69242
983 - require a later version of CPAN::Meta to ensure JSON::PP and
984 CPAN::Meta::YAML are available.
985 https://rt.cpan.org/Ticket/Display.html?id=69008
987 - hoist the per-line calculations for the flines implementations, and
988 modernize the tests a bit.
989 https://rt.cpan.org/Ticket/Display.html?id=70126
991 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
993 https://rt.cpan.org/Ticket/Display.html?id=69147
995 - if t1lib failed to reinitialize it would be left as marked
997 https://rt.cpan.org/Ticket/Display.html?id=69877
999 - update the bundled (and still modified) Devel::CheckLib
1000 https://rt.cpan.org/Ticket/Display.html?id=69170
1002 Imager 0.84_01 - 8 Aug 2011
1005 Development release as a sanity check for the types re-work.
1007 Massive types re-work:
1009 - the type used internally for pixel co-ordinates and image sizes is
1010 now 64-bit on 64-bit platforms (at least sane ones).
1012 - size_t is now used consistently for memory block sizes.
1014 - since this changes the binary interface, the Imager API version has
1015 been incremented. Any module that uses the API will need to be
1016 rebuilt. In most cases that will be enough, but calls to any APIs
1017 that take a pointer to image sizes may need source changes.
1019 - you should be able to create very large images on 64-bit systems,
1020 if you have enough memory. Successfully created a 32768 x 49192 x
1021 3 channel image, filled with a tiled image and scaled it. The
1022 unscaled image was also successfully saved to a JPEG.
1024 - check the image size before attempting to write BMP, GIF, JPEG,
1025 PNG, SGI, TGA, TIFF images.
1027 - correctly handle reading TGA images over 32767 pixels wide or tall.
1031 - the gif_left and gif_top tags are now clamped to non-negative
1032 values when writing a GIF image.
1034 - removed dead callback read/write code
1036 The default maximum memory size when reading files is now 1G.
1038 Imager 0.84 - 20 Jun 2011
1041 - Imager no longer inherits from Exporter (unless you're running an
1044 - Imager can now write progressive JPEGs (it could always read them).
1045 https://rt.cpan.org/Ticket/Display.html?id=68691
1049 - re-work, document and test Imager's logging facility.
1050 https://rt.cpan.org/Ticket/Display.html?id=65227
1052 - fix META.yml testing and the generated META.yml
1053 https://rt.cpan.org/Ticket/Display.html?id=65235
1055 - test and add error reporting to to_*() family methods
1057 - add to_rgb_double() method.
1058 https://rt.cpan.org/Ticket/Display.html?id=65101
1060 - Imager no longer exports anything by default
1061 https://rt.cpan.org/Ticket/Display.html?id=65228
1063 - convert colors to grayscale if the supplied (or generated) palette
1064 contains only grays when performing error diffusion color
1066 https://rt.cpan.org/Ticket/Display.html?id=68508
1068 - writing a paletted image to GIF wouldn't always use the colors
1069 supplied (or generated, eg. via make_colors => "mono"), which was
1071 https://rt.cpan.org/Ticket/Display.html?id=67912
1073 - replace (imager|tony)@imager.perl.org in the doc, since I don't
1074 plan to continue receiving mail at that address.
1075 https://rt.cpan.org/Ticket/Display.html?id=68591
1077 Imager 0.83 - 21 May 2011
1082 - diag() the error message on failure for some TIFF tests that are
1083 failing on a Solaris smoker.
1084 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
1086 Imager 0.82_01 - 17 May 2011
1089 Dev release, in case the compose tests are too sensitive.
1093 - Imager::Font::T1 incorrectly checked for absolute filename under
1094 Win32. Thanks to kmx for the report and fix.
1095 https://rt.cpan.org/Ticket/Display.html?id=67963
1097 - compose() with the target, source or mask position off the top or
1098 left of the target image didn't clip the source image correctly.
1099 https://rt.cpan.org/Ticket/Display.html?id=67220
1101 - compose() now returns a useful error message on a non-positive
1104 - compose.im now at 100% test coverage. (As opposed to, umm, much,
1107 Imager 0.82 - 14 Mar 2011
1112 - eliminate calls to i_has_format() from the test suite, since it's
1113 no longer a useful way to check for file format support. Eliminate
1114 i_has_format() from the functions exposed via XS.
1115 https://rt.cpan.org/Ticket/Display.html?id=65863
1117 - eliminate calls to note(), which isn't in the (very old) version of
1118 Test::More we have as a pre-requisite. note() is modern enough
1119 that I don't feel a need to require a Test::More upgrade for it.
1120 https://rt.cpan.org/Ticket/Display.html?id=65864
1122 - skip the threads tests on Test::More 2.00_*
1123 https://rt.cpan.org/Ticket/Display.html?id=65812
1125 - add an (unshipped) test to check Imager's internal POD links
1126 https://rt.cpan.org/Ticket/Display.html?id=65749
1128 - improve the library detection summary
1129 https://rt.cpan.org/Ticket/Display.html?id=9675
1131 - increase the version of Imager::Font::Type1 so that upgrades don't
1132 downgrade the version in this file.
1133 https://rt.cpan.org/Ticket/Display.html?id=66250
1135 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
1136 that option for the directories that would normally go in
1137 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
1138 https://rt.cpan.org/Ticket/Display.html?id=65955
1140 Imager 0.81 - 14 Feb 2011
1143 - added coverage tests for masked images (maskimg.c @100% test coverage)
1145 - add hsv() method to Imager::Color
1146 Thanks to Leolo (Philip Gwyn)
1147 https://rt.cpan.org/Ticket/Display.html?id=65385
1149 - split libt1 Type 1 font support into a sub-module
1150 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1152 - add a preload() class method for use in forking servers, and to
1153 work around limitations in PAR.
1154 https://rt.cpan.org/Ticket/Display.html?id=65665
1158 - paletted writes to a masked image are now masked correctly.
1159 Revealed by new coverage tests.
1161 - update the filter plugin documentation.
1162 https://rt.cpan.org/Ticket/Display.html?id=56513
1164 - add the matrix() method to Imager::Matrix2d to allow creation of a
1165 matrix with specified co-efficients. You can now multiple an
1166 Imager::Matrix2d object by a 9 element array ref or a number.
1167 https://rt.cpan.org/Ticket/Display.html?id=29938
1169 - really fix loading TTF fonts with FT2 when FT1 isn't available.
1170 Thanks to Leolo (Philip Gwyn)
1171 https://rt.cpan.org/Ticket/Display.html?id=65386
1172 https://rt.cpan.org/Ticket/Display.html?id=62855
1174 - make sure each test script that needs testout/ creates it.
1175 https://rt.cpan.org/Ticket/Display.html?id=65088
1177 - handle a slightly different warning from libtiff 4.x
1178 https://rt.cpan.org/Ticket/Display.html?id=65268
1180 - the sat transform2() op returned an incorrect saturation.
1181 https://rt.cpan.org/Ticket/Display.html?id=65391
1183 Imager 0.80 - 17 Jan 2011
1186 - added coverage tests for Imager::Fountain and Imager::Color::Float
1188 - Imager is now maintained in git
1189 http://git.imager.perl.org/imager.git
1190 git://git.imager.perl.org/imager.git
1194 - images with an translucent alpha channel were not scaled correctly
1195 by the default (qtype=normal) scaling method.
1196 https://rt.cpan.org/Public/Bug/Display.html?id=63922
1198 - Imager::Color::Float now translates "#FFFFFF" to white instead of
1199 just a little darker.
1201 - make the default color map build algorithm "mediancut". This
1202 changes the default color map builder for writing GIFs back to what
1203 it was in 0.77, reverting a performance regression.
1204 https://rt.cpan.org/Ticket/Display.html?id=64785
1206 - handle failure to create a masked image correctly
1208 Imager 0.79 - 10 Dec 2010
1211 - add Imager::Test to the POD coverage tests and document the missing
1214 - the convert() method now optimizes the case where all output
1215 channels are either 0, sourced from a single input channel or 1.
1216 This significantly speeds up presets like "addalpha", "green".
1217 https://rt.cpan.org/Ticket/Display.html?id=51254
1219 - add wiggle.pl sample, as suggested by Dan Oppenheim.
1221 - add the combine() method to combine channels from multiple source
1222 images into a new image
1223 https://rt.cpan.org/Ticket/Display.html?id=11872
1227 - treat the co-efficients for convert() as doubles instead of floats.
1229 - If a higher (earlier) priority font handler failed to load, that
1230 would crash preventing loading of later font handlers.
1231 https://rt.cpan.org/Ticket/Display.html?id=62855
1233 - parse defines from the options returned by pkg-config --cflags
1234 https://rt.cpan.org/Ticket/Display.html?id=63223
1236 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
1237 included in the tarball. They are now included.
1239 Imager 0.78 - 4 Oct 2010
1244 - don't access deprecated members of the png_structp.
1245 https://rt.cpan.org/Ticket/Display.html?id=60242
1247 - document that using color objects is faster than supplying colors
1249 https://rt.cpan.org/Ticket/Display.html?id=61047
1251 - Imager::Probe now accepts array references for incpath and libpath.
1252 https://rt.cpan.org/Ticket/Display.html?id=60244
1254 Imager 0.77_02 - 27 Sep 2010
1257 - moved Win32, FreeType 2 font support into sub-modules.
1258 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1259 Uses Imager::Probe now.
1260 https://rt.cpan.org/Public/Bug/Display.html?id=61328
1262 - tested successfully with jpeg-8b
1263 https://rt.cpan.org/Ticket/Display.html?id=60221
1267 - from _01: look for missing file support test files in the right
1270 - flood_fill() wouldn't fill the right side of a single scan-line
1272 Thanks to Nicolas Roggli for reporting this.
1274 - flood_fill wouldn't fill to the left edge of the image if the
1275 starting line didn't reach the left edge.
1276 Thanks to Nicolas Roggli for reporting this.
1278 Imager 0.77_01 - 13 Sep 2010
1281 - add each library-directory/pkgconfig/ to the pkg-config search path
1283 Thanks to Justin Davis.
1284 https://rt.cpan.org/Ticket/Display.html?id=60491
1286 - moved GIF, TIFF, JPEG file handling code into sub-modules in
1287 preparation for separate distribution.
1288 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1290 Note: this removed support for libungif from Imager.
1292 - optimize filled box drawing (color, not fill)
1296 - Imager::Probe was calling ExtUtils::Liblist to initialize
1297 LD_RUN_PATH supplying an undefined value rather than the found
1298 directory. Thanks to Justin Davis.
1299 https://rt.cpan.org/Ticket/Display.html?id=60491
1301 - only prepend ./ to font filenames when passing them to T1Lib and
1302 then only when it would use its search mechanisms.
1303 https://rt.cpan.org/Ticket/Display.html?id=60509
1305 - fix the cache check for the X rgb.txt loader. This is typically
1306 used for color translation on Unix-like systems, and the fix
1307 improves performance of supplying colors by name by about 80 times.
1308 Test code that managed 3400 10x10 pixel boxes/second sped up to
1311 - clarify that Imager doesn't write EXIF metadata to images.
1312 https://rt.cpan.org/Ticket/Display.html?id=60637
1314 - Imager::Probe can now search subdirectories under its include path.
1315 Used by the PNG Makefile.PL to find headers and libraries when they
1316 aren't in the base directory, as in cygwin.
1317 https://rt.cpan.org/Ticket/Display.html?id=60635
1319 Imager 0.77 - 11 Aug 2010
1322 I don't want Imager::File::PNG indexed as part of Imager, but forgot
1323 to update the META.yml before updating the version.
1325 - don't index Imager::File::PNG as part of Imager
1327 - add resources to META.yml
1329 Imager 0.76 - not released
1334 - the align_string() method would ignore a string of "0" due to a
1335 mis-use of C< ||= >.
1336 Thanks to Maurice Height for reporting this.
1337 https://rt.cpan.org/Ticket/Display.html?id=60199
1339 Imager 0.75_03 - 09 Aug 2010
1344 - read_types() and write_types() would include png when it wasn't
1345 available due to a problem with the %formats tie
1347 - handle dependent libraries correctly (eg -lpng requiring -lz) in
1348 the code run phase of library probing.
1350 Imager 0.75_02 - 07 Aug 2010
1355 - add file missing from MANIFEST, which was causing TIFF failures.
1357 Imager 0.75_01 - 06 Aug 2010
1360 Test release for the new PNG probe.
1362 - added the ability to read multiple-image PNM files.
1363 Note that unlike the pbm/pgm/ppm specification this accepts mixed
1364 format files and allows white space padding between files.
1365 Thanks to Philip Gwyn (Leolo) for this patch.
1367 - moved the PNG file handling code into a sub-module in preparation
1368 for separate distribution.
1369 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1370 Also helps avoid complications from -I/-L compile/link options from
1375 - Imager->new(data => $data) didn't try to process image file data in
1377 https://rt.cpan.org/Ticket/Display.html?id=58761
1379 - t/t50basicoo.t no longer depends on the other tests to generate its
1381 https://rt.cpan.org/Ticket/Display.html?id=9798
1382 Also, it wasn't testing pnm (pnm vs ppm mix-up)
1384 - update the documentation of hardinvert to match the change in 0.62.
1385 https://rt.cpan.org/Ticket/Display.html?id=59785
1387 - added hardinvertall filter which also inverts the alpha channel
1388 (sorry for the mess)
1390 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
1391 the probe can find the library for the test run.
1392 https://rt.cpan.org/Ticket/Display.html?id=57518
1394 Imager 0.75 - 20 Jun 2010
1397 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
1398 perls (not measured)
1402 - an opacity fill based on a fountain fill would segfault when
1403 filling an 8-bit/sample image.
1405 - merge thickline branch polygon fix
1406 https://rt.cpan.org/Ticket/Display.html?id=43518
1408 Imager 0.74 - 7 May 2010
1413 - read_multi() didn't handle a missing file format library correctly,
1414 aborting on failing to call i_readgif_multi_wiol() or
1415 i_readtiff_multi_wiol().
1417 - fix spelling errors patched by Debian
1418 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
1420 - add an (unshipped) author test to spellcheck Imager's POD.
1422 - update the TIFF file format documentation
1423 https://rt.cpan.org/Ticket/Display.html?id=56510
1425 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
1427 Imager 0.73 - 15 Mar 2010
1430 - implement outline circles, both anti-aliased and not
1431 https://rt.cpan.org/Ticket/Display.html?id=19755
1433 - a combine => "none" fill to a 1 or 3 channel image would produce
1434 the incorrect colour.
1436 Imager 0.72 - 09 Dec 2009
1439 Bump version for release, since 0.71_03 is stable with CPAN testers.
1441 Imager 0.71_03 - 5 Dec 2009
1444 - further adjust the threads test so it only performs the tests on
1445 perls where it's expected to work, and only if the threads module
1448 Imager 0.71_02 - 1 Dec 2009
1451 - adjust the way we load the threads module for the threads test so
1452 it works with non-threaded perls
1454 Imager 0.71_01 - 30 Nov 2009
1459 - use scanline oriented operations to flip images instead of pixel
1461 https://rt.cpan.org/Ticket/Display.html?id=39278
1463 - use double/sample operations to flip large sample images instead of
1464 8-bit sample operations.
1465 https://rt.cpan.org/Ticket/Display.html?id=39280
1468 https://rt.cpan.org/Ticket/Display.html?id=51874
1470 - prevent double-frees when someone creates Imager objects and then
1471 creates a thread. Note: this just handles some simple cases,
1472 Imager doesn't support perl threads, and isn't likely to.
1473 https://rt.cpan.org/Ticket/Display.html?id=52268
1475 Imager 0.71 - 16 Nov 2009
1478 - add the opacity fill type - an adaptor that modifies the opacity of
1483 - the conv filter now enforces that the sum of the coefficients is
1484 non-zero. Also, rather than skipping pixels off the edge off the
1485 edge of the image, the closest edge pixel is used. Previously
1486 dividing by the zero sum of coefficients could cause invalid
1487 results or runtime exceptions.
1488 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
1491 Imager 0.70 - 21 Sep 2009
1496 - release image row and comments memory on all error returns in gif
1499 - handle zero length extensions, previously this would cause a null
1501 Thanks to Krzysztof Wojtaś for the test data and fix for this.
1503 - an integer division meant that preview scaling to below 1 pixel
1504 wide or high (which isn't too useful anyway) was calculating using
1505 NaNs on most platforms, and causing an exception on others.
1506 Thanks to David Cantrell for producing a backtrace of the crash on
1507 his Alpha-NetBSD CPAN test box which made it possible to track this
1510 Imager 0.69 - 08 Sep 2009
1515 - broken test fix - was attempting to call a function skip_all, when
1516 that should be a parameter to plan().
1518 - briefly document apidocs.perl, the tool used to build
1519 Imager::APIRef and make some minor enhancements
1521 - various minor documentation enhancements and fixes.
1523 Imager 0.68 - 07 Sep 2009
1526 - Imager->new(file => $filename) and other similar incantations will
1527 load the given file.
1528 https://rt.cpan.org/Ticket/Display.html?id=48261
1532 - avoid using CHECK as a label in Imager::Test
1533 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
1535 - re-work most image file test files that require a library into
1536 separate library present/not present files to remove stupidly long
1539 - don't treat rubthrough() outside the bounds of the target image as
1541 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
1543 Imager 0.67_01 - 02 Sep 2009
1548 - correct documentation of default of raw image interleave read
1550 https://rt.cpan.org/Ticket/Display.html?id=42074
1552 - add raw_ prefix to raw read parameters, though the original names
1555 - fail the read if an invalid raw_interleave parameter is supplied
1557 - warn if no interleave or raw_interleave parameter is supplied,
1558 since the documented default was wrong, and incompatible with the
1561 - for reading raw images, if raw_storechannels > raw_datachannels,
1562 set the extra channels in the image to 0
1564 - when probing for executables like freetype-config, search for .bat
1565 and .cmd on MSWin32, as well as .exe.
1566 https://rt.cpan.org/Ticket/Display.html?id=49275
1568 - re-work the external libraries section of README:
1569 - list Debian and Redhat package names for each library
1573 - use the new EU::MM META_MERGE facility instead of generating
1574 META.yml from scratch
1575 https://rt.cpan.org/Ticket/Display.html?id=47888
1577 - use Devel::CheckLib (bundled, modified) to check which release of
1578 libtiff is installed and reject 3.9.0
1579 http://bugzilla.maptools.org/show_bug.cgi?id=2088
1580 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
1582 Imager 0.67 - 12 Dec 2008
1587 - fix a packaging error
1589 Imager 0.66 - 12 Dec 2008
1592 - 24-bit color .ICO/.CUR files can now be read.
1596 - an optimization skipping 0 src alpha values could cause the
1597 rubthrough() to read past the end of a buffer.
1598 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
1600 - corrected a reference leak where writing GIFs would leak memory.
1601 This could also happen calling to_paletted().
1602 Also documented the underlying long existing feature where the
1603 colors parameter is filled with the generated color table and added
1605 http://rt.cpan.org/Ticket/Display.html?id=41028
1607 - write out the image size in bytes field of a BMP correctly.
1608 http://rt.cpan.org/Ticket/Display.html?id=41406
1610 - add limited tests for Imager::ExtUtils
1612 - make Imager::ExtUtils->includes use an absolute path, since
1613 a relative path could cause failures using Inline::C.
1614 http://rt.cpan.org/Ticket/Display.html?id=37353
1616 - re-arrange the POD for Imager::Font::BBox:
1617 - mark total_width(), pos_width(), end_offset() obsolete, since
1618 they're mostly for backwards compatibility
1619 - group width methods and height methods
1620 https://rt.cpan.org/Ticket/Display.html?id=39999
1622 Imager 0.65 - 20 May 2008
1627 - In some cases when an error occurs reading those parts of a JPEG
1628 file after the image the scan-line buffer could be freed a second
1629 time. In cases where the the error occured while reading the image
1630 data it's possible that the buffer could have leaked.
1631 Thanks to Gabriel Vasseur for reporting this and help in tracking
1634 - the gif_screen_height tag was overriding the screen width and being
1635 ignored for the screen height when present.
1636 https://rt.cpan.org/Public/Bug/Display.html?id=35568
1638 Imager 0.64 - 23 April 2008
1641 This is a bug fix release. This includes a fix for a possible
1646 - Possible security issue: The floating point sample path for image
1647 based fills had a buffer overflow. This would overwrite the end of
1648 a malloc()ed buffer with double precision floats.
1649 http://rt.cpan.org/Ticket/Display.html?id=35324
1652 - check that the result of fileno($fh) is defined rather than simply
1653 true when read() or write() is supplied with an fh parameter.
1654 http://rt.cpan.org/Ticket/Display.html?id=35139
1656 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1657 resulting in a SIGSEGV when attempting to scale an image to a size
1658 too large to fit in memory. This is a NULL pointer access issue,
1659 not a buffer overflow.
1660 Added a check for the failure.
1661 scale_calculate() (and hence scale()) will now fail if any of the
1662 scale size parameters are a reference.
1663 http://rt.cpan.org/Ticket/Display.html?id=35172
1665 - Regression: filling a greyscale image with a hatch used the wrong
1666 color channels from the supplied fg/bg colors.
1667 https://rt.cpan.org/Ticket/Display.html?id=35278
1669 - fixed a related problem for image fills.
1671 Imager 0.63 - 7 April 2008
1674 This release primarily contains changes to improve ease of use -
1675 rather than you having to convert images to the appropriate number of
1676 channels, Imager handles it internally. How to handle drawing colors
1677 and the default combine mode is a thornier problem left for some other
1680 - the font libraries are now only initialized when needed.
1681 http://rt.cpan.org/Ticket/Display.html?id=28825
1683 - moved the imtoc.perl code into Imager::Preprocess
1685 - paste() and rubthrough() now adapt the source image data to the
1686 destination, so you can now safely paste/rubthrough from greyscale
1687 images to color images or back, or from alpha channel images to
1688 noalpha channels or back.
1689 https://rt.cpan.org/Ticket/Display.html?id=30908
1691 - rubthrough() now falls back to pasting when the source doesn't have
1692 an alpha channel. This effectively treats the source as having a
1693 max alpha channel, the right thing to do.
1694 http://rt.cpan.org/Ticket/Display.html?id=29944
1696 - re-worked most of the area filling code to use a common set of
1697 functions when filling.
1698 Corrected normal combine mode.
1699 Rewrote most of the combine modes to match the way the SVG draft
1700 defines them with respect to a translucent source and destination.
1701 Added tests for translucent source and destination.
1702 Added tests to check 8-bit/sample and double/sample combines work
1704 https://rt.cpan.org/Ticket/Display.html?id=29879
1706 - writing a 2 or 4 channel image to a JPEG file will now write that
1707 image as if composited against a background, black by default,
1708 overridable with the i_background tag/parameter.
1709 https://rt.cpan.org/Ticket/Display.html?id=29876
1711 - writing a 2 or 4 channel image to a PGM/PPM file will now write
1712 that image as if composited against a background, black by default,
1713 overridable with the i_background tag/parameter.
1714 http://rt.cpan.org/Ticket/Display.html?id=30074
1716 - writing a 2 or 4 channel image to a BMP file will now write that
1717 image as if composited against a background, black by default,
1718 overridable with the i_background tag/parameter.
1719 http://rt.cpan.org/Ticket/Display.html?id=30075
1723 - Imager::Matrix2d->translate() now only requires one of the x or y
1725 http://rt.cpan.org/Ticket/Display.html?id=29937
1727 - mixing qtype scaling now sets all channels of a pixel to zero if
1728 the pixel has zero coverage (zero alpha). This should produce more
1729 compressible output files.
1730 http://rt.cpan.org/Ticket/Display.html?id=32324
1732 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
1734 https://bugzilla.redhat.com/show_bug.cgi?id=166254
1735 I'm not changing the #! lines of the sample code, since it's sample
1736 code, not intended for installation.
1737 http://rt.cpan.org/Ticket/Display.html?id=33408
1739 - some TGA images weren't being detected correctly as TGA images
1740 https://rt.cpan.org/Ticket/Display.html?id=32925
1742 - handling of the left-over bit for 16-bit/pixel TGA images has been
1743 changed to match the behaviour of the GIMP. Previously the bit
1744 being set was treated as an opaque pixel, but one user reported a
1745 problem with loading such an image. I haven't been able to find any
1746 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1747 I'll match it's behaviour. See issue 114913 in the GIMP's
1749 http://rt.cpan.org/Ticket/Display.html?id=32926
1751 Imager 0.62 - 10 December 2007
1754 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
1755 to /path under your home directory.
1756 http://rt.cpan.org/Ticket/Display.html?id=29484
1758 - the old dynaload code used Mach API functions to load dynamic
1759 libraries on Mac OS X. These APIs have been deprecated in OS X
1760 10.5 and were causing some build problems.
1761 So henceforth Imager uses the dlopen() family of functions, and you
1762 will need version 10.3 or later of OS X.
1764 - added the det() function to the transform2() engine.
1765 added the sample quad_to_square.pl
1766 Courtesy Richard Fairhurst.
1767 http://rt.cpan.org/Ticket/Display.html?id=31244
1771 - samples/gifscale.pl sourced the base value for gif_top from
1773 Thanks to Eleneldil G. Arilou for pointing this out.
1775 - t/t82inline.t no longer loads B at runtime, to work around a bug
1776 in some 5.005_0[45] installations.
1777 http://rt.cpan.org/Ticket/Display.html?id=30508
1779 - work around Module::Depends::Intrusive bug #21229
1780 http://rt.cpan.org/Ticket/Display.html?id=30520
1782 - the hardinvert filter no-longer inverts the alpha channel.
1783 http://rt.cpan.org/Ticket/Display.html?id=30002
1785 - the hardinvert filter now supports large samples
1787 Imager 0.61_02 - 28 November 2007
1790 - major TIFF support re-work
1791 http://rt.cpan.org/Ticket/Display.html?id=20329
1793 - added a C level image interface for accessing samples from 1-32
1794 bits, exposed this at the perl level in getsamples()
1796 - the conv filter now works at floating point precision for high bit
1799 - added is_bilevel method to test whether an image should be written as
1800 a bilevel image if the image format supports it.
1802 - added -log-stderr as an Imager import list option
1804 - added some important types to Imager::APIRef
1806 - added test_image_double() to Imager::Test
1810 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
1813 - the scale() method with qtype mixing now handles images with an
1814 alpha channel correctly.
1816 - fixed a broken link from the "animated GIF" entry in the concept index.
1817 Thanks to Slaven Rezic.
1818 http://rt.cpan.org/Ticket/Display.html?id=30889
1820 - on some perl's the infix expression parser test would fail due to
1821 actions in the grammar returning false. Made sure all actions return
1823 Thanks to Richard Fairhurst for spending a lot of time in tracking
1825 http://rt.cpan.org/Public/Bug/Display.html?id=29562
1827 Imager 0.61 - 5 November 2007
1830 - added samples/gifscale.pl, which adjusts the screen size/position tags
1831 when scaling an animated gif
1832 http://rt.cpan.org/Ticket/Display.html?id=27591
1836 - correct handling of sz in matrix_transform() - this should allow
1837 perspective type transformations to work now.
1838 http://rt.cpan.org/Ticket/Display.html?id=29936
1840 - prevent a cast to integer warning on x64 builds in datatypes.c
1841 also fixed some other type warnings
1842 https://rt.cpan.org/Ticket/Display.html?id=30204
1844 - some sub-directory tests depended on files produced by the parent
1846 http://rt.cpan.org/Ticket/Display.html?id=30203
1848 - Imager::Font::Wrap doesn't correctly set savepos
1849 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
1850 http://rt.cpan.org/Ticket/Display.html?id=29771
1852 - test 171 in t/t01introvert.t was failing on perls configured to
1854 http://rt.cpan.org/Ticket/Display.html?id=29413
1856 - the code for the transform2() uminus operator was missing a break.
1857 Added tests for better code coverage of the ops.
1858 http://rt.cpan.org/Ticket/Display.html?id=29296
1860 - the SGI RLE compression code could overflow its compression buffer
1861 http://rt.cpan.org/Ticket/Display.html?id=30334
1863 - the 32-bit output function used by the SGI code only handled values
1864 under 0x10000. This was most noticable when writing large RLE images.
1865 http://rt.cpan.org/Ticket/Display.html?id=30335
1867 - validate chan_count for chans == NULL for each of the i_gsamp()
1869 http://rt.cpan.org/Ticket/Display.html?id=28985
1871 - attempt to work around the test failure at
1872 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
1873 http://rt.cpan.org/Ticket/Display.html?id=29562
1875 - improve the error messages produced when attempting to read or write
1876 an unknown image file format.
1877 http://rt.cpan.org/Ticket/Display.html?id=30103
1879 - improve the transform2() documentation
1880 http://rt.cpan.org/Ticket/Display.html?id=29267
1882 - correctly generate the author key in META.yml
1883 http://rt.cpan.org/Ticket/Display.html?id=30377
1885 - correctly blend a rotated (or matrix_transformed()) image when
1886 performing interpolation in the presence of an alpha channel.
1887 Also corrected the centring of the rotated image on the output
1890 Imager 0.60 - 30 August 2007
1893 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
1894 now has full SGI RGB image format, including RLE and 16-bit/sample
1896 https://rt.cpan.org/Ticket/Display.html?id=8666
1898 - logging functions are now available in the API
1900 - applied Gabriel Vasseur's patch
1901 added documentation, further tests, and support for greyscale images
1902 Obviously problems are my fault :)
1903 https://rt.cpan.org/Ticket/Display.html?id=28142
1905 - the mask for ICO/CUR images is now applied as an alpha channel to
1906 the returned image. For the old behaviour, supply ico_masked => 0
1907 to read() or read_multi(). This should be less confusing when
1908 using Imager as a general image processor.
1909 https://rt.cpan.org/Ticket/Display.html?id=29001
1913 - in some cases it's possible for giflib/libungif to return color
1914 indexes outside the range of colors defined by the image's palette.
1915 We now expand the palette to match the indexes used.
1916 Thanks to Gabriel Vasseur for reporting this.
1918 - fixed various memory leaks that could occur when failing to read png,
1919 jpeg, bmp or tga files.
1921 - to avoid confusion, channels not present in the image are returned as
1922 zero by getscanline(). This has no effect on the C level i_glin()
1923 and i_glinf() API functions which continue to not set the unused
1926 - the convert() method now returns an image of the same sample size as
1928 https://rt.cpan.org/Ticket/Display.html?id=28492
1930 - remove repeated text in Imager::Files
1931 http://rt.cpan.org/Ticket/Display.html?id=27589
1933 - be even more explicit that scale() and friends don't modify the source
1934 image, but return a new image.
1935 http://rt.cpan.org/Ticket/Display.html?id=28570
1937 - improve the error message from errstr() when you try to load a font
1938 for which the driver hasn't been built in Imager.
1939 http://rt.cpan.org/Ticket/Display.html?id=27571
1941 - transparency is now enabled by default when writing GIF images
1942 http://rt.cpan.org/Ticket/Display.html?id=27615
1944 - Imager would not load on Windows 98
1945 http://rt.cpan.org/Ticket/Display.html?id=27653
1947 Imager 0.59 - 14 June 2007
1952 - fixes a regression introduced by the fixes for RT 11972
1953 http://rt.cpan.org/Ticket/Display.html?id=27546
1955 - cropping outside the image would return an Imager object with
1956 no low-level image object, instead of returning false.
1957 Fixed by: Philip Gwyn (Leolo)
1958 http://rt.cpan.org/Ticket/Display.html?id=27509
1960 Imager 0.58 - 16 May 2007
1963 No significant changes from 0.57_01.
1965 Imager 0.57_01 - 11 May 2007
1968 - added to_rgb16 to produce a 16-bit/sample version of an image
1970 - improve freetype 1.x text output efficiency
1974 - search another place for rgb.txt, and check all the places
1975 Imager::Color checks when deciding whether to skip testing it
1976 http://rt.cpan.org/Ticket/Display.html?id=26064
1978 - use a convolution kernel size based on the stddev rather than a
1979 fixed size when performing a gaussian blur
1980 http://rt.cpan.org/Ticket/Display.html?id=25645
1982 - document the difference() method's mindist parameter, and debug it.
1984 - put the Imager release number in the Inline::C generated code to
1985 regenerate Inline code when a new release of Imager is installed.
1986 http://rt.cpan.org/Ticket/Display.html?id=26278
1988 - fix rendering on alpha channel images for the FreeType 1.x driver.
1989 http://rt.cpan.org/Ticket/Display.html?id=11972
1991 - fix rendering on alpha channel images for the T1lib driver.
1992 http://rt.cpan.org/Ticket/Display.html?id=11972
1994 - reworked library probing, we can now set more than one probe
1995 function for a library. Disabled the default (non-freetype-config)
1996 library probe and added an extra probe function that searches for
1997 both ft2build.h and whatever it includes, and adds -I as needed.
1998 Hopefully this will fix build problems like
1999 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
2000 http://rt.cpan.org/Ticket/Display.html?id=26086
2002 Imager 0.57 - 30 Apr 2007
2005 This is a maintenence release fixing a security issue in Imager.
2007 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
2008 overflow in malloced memory. There will be further discussion of
2009 this issue in the ticket below.
2010 http://rt.cpan.org/Ticket/Display.html?id=26811
2011 CVE-2007-2459 CVE-2007-2413
2012 The descriptions at cve.mitre.org varied in quality, please see the
2013 ticket at rt.cpan.org for a more accurate description of the issue.
2015 Imager 0.56 - 1 Apr 2007
2018 - added support for reading 16-bit/sample PGM/PPM images
2020 - added support for writing 16-bit/sample PGM/PPM images
2022 - improved performance of reading PBM/PGM/PPM images
2024 - added support for writing PBM images if the image is paletted and
2025 contains only black and white
2027 - added a new make_colors value - "mono"
2029 - switched from the svn log Changes to a manual Changes to reduce
2032 - new sample code - samples/flasher.pl
2036 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
2037 was returning an image object with an extra reference, this
2038 resulted in a memory leak.
2039 http://rt.cpan.org/Ticket/Display.html?id=24992
2041 - fix rendering on alpha channel images for the FreeType 2.x driver
2042 http://rt.cpan.org/Ticket/Display.html?id=11972
2044 - reading bmp files now consitently handles short reads. You can now
2045 supply a parameter to treat a short read as successful and set
2047 http://rt.cpan.org/Ticket/Display.html?id=8426
2049 - previously, reading ASCII PBM files required spaces between samples,
2050 even though the format doesn't require that
2052 - improved documentation of the unsharpmask filter (I hope)
2053 http://rt.cpan.org/Ticket/Display.html?id=25531
2055 - force flushing of the output from i_tt_dump_names() and test output
2056 in t/t35ttfont.t to prevent output from being mixed up.
2057 https://rt.cpan.org/Ticket/Display.html?id=24859
2059 - rewrite a conditional expression as an if() to hopefully work around
2060 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
2061 https://rt.cpan.org/Ticket/Display.html?id=25561
2063 - avoid Data::Dumper in regops.perl to support older releases of perl
2064 https://rt.cpan.org/Ticket/Display.html?id=24391
2066 Imager 0.55 - 16 Dec 2006
2069 This is primarily a bug fix release.
2071 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2073 There is one new feature:
2075 - the Win32 font driver now supports UTF8 (RT 22166)
2076 http://www.cpanforum.com/threads/3276
2077 http://rt.cpan.org/Ticket/Display.html?id=22166
2079 Several bugs were fixed:
2081 - the string() method would not output the string "0"
2082 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2084 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2085 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2087 - the gif_disposal and gif_user_input tags weren't being read from
2089 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2091 - gif.c was failing to build under MSVC
2092 http://rt.cpan.org/Ticket/Display.html?id=23922
2094 - in some cases strings passed to the string() method were treated as
2095 terminated by NUL (chr 0)
2096 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2098 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2099 that's the default build name for zlib on Win32.
2100 http://rt.cpan.org/Ticket/Display.html?id=23064
2102 - search $Config{incpath} for headers too, which we should have been
2105 Win32 font driver fixes:
2107 - the global descent value from bounding box was the wrong sign
2108 http://www.cpanforum.com/threads/3276
2110 - if the first or last glyph overflowed the left or right side of the
2111 advance width they would be clipped
2114 Imager 0.54 - 14 Sep 2006
2117 This is primarily a feature release:
2119 - a new qtype value 'mixing' has been added to the scale()
2120 method. This is faster than 'normal', slower than 'preview'. This
2121 is based on the method used by pnmscale, and seems to produce less
2122 blurry results than normal.
2123 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2125 - the rubthrough() method can now render onto images with an alpha
2127 http://rt.cpan.org/Ticket/Display.html?id=20678
2129 - the read_multi() method now falls back to calling doing a single
2130 image read via the read() method and write_multi() will now fall
2131 back to calling write() if a single image is supplied. This means
2132 you can simply call the read_multi() or write_multi() functions
2133 without having to check if the type is formatted by that method.
2134 http://rt.cpan.org/Ticket/Display.html?id=19457
2135 http://rt.cpan.org/Ticket/Display.html?id=19458
2137 - the GIF loop extension can now be written. If you don't have
2138 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2140 http://rt.cpan.org/Ticket/Display.html?id=21185
2142 - getscanline() and setscanline() can now read/write palette index
2143 based data from/to the image for paletted images, by setting type to
2145 http://rt.cpan.org/Ticket/Display.html?id=20338
2147 - we no longer hassle you to disable GIF support
2148 http://rt.cpan.org/Ticket/Display.html?id=20687
2150 - minor documentation fixes
2153 Imager 0.53 - 26 Jul 2006
2156 This is a bugfix release.
2158 Some test code was left in a code path not covered by the test
2159 suite. A test was added to cover this code path and the test code was
2161 http://rt.cpan.org/Public/Bug/Display.html?id=20705
2164 Imager 0.52 - 25 Jul 2006
2167 This is primarily a feature release, but contains a fair few bug
2168 fixes, new features:
2170 - ability to read and write MS Windows ICO and CUR files
2172 - you can now add file format plugins to support new file formats
2174 - add POD coverage tests
2176 - setcolors() and addcolors() now accept color names and so on
2177 instead of requiring Imager::Color objects.
2178 http://rt.cpan.org/Ticket/Display.html?id=20056
2180 - flood_fill() can now fill to a specified border color instead of
2181 just to the area the same color as the seed.
2182 http://rt.cpan.org/Ticket/Display.html?id=19618
2187 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2188 calculating the advance width.
2189 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2191 - bounding_box for the T1 driver wasn't including leading and
2192 trailing spaces in the bounding box as the other drivers did, it also
2193 produced strange results for empty strings or strings containing only
2196 - when reading CMYK jpeg images they were being transferred to the
2197 image object as is, producing a four channel image. It only looked ok
2198 due to an old still unfixed Photoshop bug. We now convert from the
2199 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2200 http://rt.cpan.org/Ticket/Display.html?id=20416
2202 - reading a CYMK TIFF would result in a 4 channel image, reading any
2203 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2205 http://rt.cpan.org/Ticket/Display.html?id=20415
2207 - added /usr/local/include to the default include search path, since
2208 we were already searching /usr/local/lib for libraries.
2210 And various minor fixes and documentation updates.
2213 Imager 0.51 - 23 Apr 2006
2216 - fix a validation bug when processing JPEG EXIF data that can cause
2218 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2220 - fix mis-processing of the src_maxx and src_maxy parameters of the
2222 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2224 - fix a problem in Imager's "smart" handling of the color parameter
2226 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2229 Imager 0.50 - 29 Mar 2006
2232 - CRITICAL: fixes a segmentation fault from attempting to write a 2
2233 or 4 channel image to jpeg or a 2 channel image to tga where the
2234 output is an in-memeory buffer.
2235 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2237 - fixes an incorrect pointer parameter in the PNG code
2238 http://rt.cpan.org/Public/Bug/Display.html?id=18051
2240 - skip Inline::C tests when building in a directory with spaces
2241 http://rt.cpan.org/Public/Bug/Display.html?id=18049
