1 Imager release history. Older releases can be found in Changes.old
3 - add some extra error reporting to the I/O layers tests, this might
4 help catch a failure seen on Win32.
5 http://cpantesters.org/cpan/report/99781689-6bf5-1014-897a-75cb4eee1325
7 Imager 1.004_002 - 20 Mar 2016
10 - don't use the seek() method on opened() handles in
11 t/200-file/400-basic.t. In older versions of perl such handles are
12 only IO::Handle objects, not IO::File, and don't have a seek()
15 Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
18 - re-work the t/200-file/400-basic.t to correctly handle failures
19 It's custom ok() function didn't have a prototype and didn't use scalar().
20 This caused ok() to use the note instead of the value being tested when
21 the method called returned an empty list. For an example of the problem
22 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
24 - remove some noise from when Imager tried to work with bugs in old
25 versions of giflib. I can't do much about the new bugs.
27 - the new autolevels filter (Imager 0.99) used an integer for the
28 sample scaling factor which caused the top output level to be too
29 low (depending on the scaling required.) It now uses a double.
30 https://rt.cpan.org/Ticket/Display.html?id=111871
32 - the new autolevels filter had off-by-one errors calculating the
33 minimum and maximum luminance from the histogram. This slightly
34 reduced the contrast of the output image.
35 https://rt.cpan.org/Ticket/Display.html?id=111871
37 - the new autolevels filter now uses a lookup table for 8-bit images
38 to avoid a floating point multiply for each sample.
39 https://rt.cpan.org/Ticket/Display.html?id=111871
41 - fixed several memory leaks detected by valgrind:
43 - addcolors() leaked the temporary array of colors supplied to the
46 - make_palette() leaked the temporary image array (not the images
47 themselves) passed to the internal API.
49 - combine()/i_combine() leaked its working row buffers
51 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
52 buffer if there were too many colors
54 - getcolorcount()/i_count_colors() leaked the sample buffer if
55 there were too many colors.
57 - the nearest_color filter (undocumented until I find a use for it)
58 leaked both temporaries passed to the API and internal buffers
60 - the internal process of upgrading a paletted image to a direct
61 color image would leak a context object reference count.
63 - a write failure when writing to a GIF file could leak memory.
65 - failing to write to a 1-bit/pixel ICO image could leak memory.
67 - Imager no longer deliberately leaks the context object from the
68 initial thread. This was done to ensure there was always a context
69 object available, but the code that needed that now handles the
72 - fixed some uninitialized memory usage detected by valgrind:
74 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
75 i_matrix_transform_bg() didn't initialize a working color value
76 if there was zero pixel coverage.
78 - i_ft2_cp() didn't initialize the complete color when producing an
79 intermediate image. This caused uninitialized value usage when
82 Imager 1.004 - 8 Nov 2015
85 - Imager::Color::Table is now pre-loaded by the preload() method.
86 https://rt.cpan.org/Ticket/Display.html?id=104896
88 - fix an assertion triggered under perl 5.23.4.
89 Thanks to A. Sinan Unur for the report and the patch.
91 - Imager->new can now be used to read raw image files.
92 https://rt.cpan.org/Ticket/Display.html?id=106836
93 Thanks to Richard Kelsch for reporting this.
95 - deal with output changes from Pod::Spell
96 https://github.com/perl-pod/Pod-Spell/issues/21
98 Imager 1.003 - 12 May 2015
101 - update 1.002 release notes to include the center change for filled
104 - flood_fill() would escape beyond a 4-connected space under some
106 Added many more flood_fill() tests.
107 https://rt.cpan.org/Ticket/Display.html?id=103786
109 Imager 1.002 - 3 Apr 2015
112 - drawing anti-aliased filled circles is now 10 to 50 times faster
113 depending on the size of the circle.
114 This also changed the center from being the center of the pixel to
115 being the top left of the pixel to match the filled arcs drawn by
117 https://rt.cpan.org/Ticket/Display.html?id=101682
119 - enhancements to polygon filling:
121 - added a mode parameter to control how overlapping regions behave
123 - added a polypolygon() method to fill more than one polygon at a
126 - polygon filling is now exposed through the API.
128 - added colormodel(), alphachannel() and colorchannels() methods.
129 These were added for two reasons:
131 - a future version of Imager may allow the number of channels in
132 an image to not directly represent the color model of an image.
133 eg. a greyscale TIFF image with multiple alpha channels.
135 - a future version of Imager may allow an image to be read without
136 translation, for example a TIFF file that contains measurements
137 from an instrument. Currently Imager transforms the samples into
138 the range 0.0 ... 1.0 which may means the user has to translates
141 An untranslated image would be unusable as image data, so
142 colormodel() would return "unknown" in this case.
144 Similarly a CMYK image might be returned as an "unknown" color
145 model image, if the caller chooses to disable translation to
148 Imager 1.001 - 2 Jan 2015
151 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
152 Thanks to Slaven Rezic for the report and the patch.
153 https://rt.cpan.org/Public/Bug/Display.html?id=98234
155 - GIF: clean-up a test file if the test for the giflib 4.2.0 file
158 - fix Imager::Matrix2d::rotate()'s centre point handling
159 https://rt.cpan.org/Public/Bug/Display.html?id=99959
161 - ICO: don't apply the icon mask to images with an alpha channel by
163 https://rt.cpan.org/Public/Bug/Display.html?id=99507
165 - make verbose probing output more verbose
167 - use Imager::Probe to probe for freetype 1.x
168 https://rt.cpan.org/Ticket/Display.html?id=100502
170 - The --enable and --disable parameters to the top-level Makefile.PL
173 - update the bundled/modified Devel::CheckLib to handle the gcc-4
176 Imager 1.000 - 28 Jul 2014
179 There's nothing special about Imager 1.000, it's just another release.
181 - fix the skip check for the iolayer qr// buffer test
183 - improve error reporting for the iolayer test failing on a small
184 number of Win32 CPAN testers
186 Imager 0.99_02 - 21 Jul 2014
189 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
190 the blue channel in the generated palette, and allow each color
191 component to be in the range 100..255 instead of just 100..254.
192 Thanks to Ralf Neubauer.
193 https://rt.cpan.org/Ticket/Display.html?id=97086
195 - revert "improved the XS for i_io_read() and i_io_raw_read()"
196 This caused problems with older perls and didn't provide much of a
197 performance improvement.
199 - support Inline 0.57 and later.
200 Inline 0.57 changed the "with" interface.
201 https://rt.cpan.org/Ticket/Display.html?id=97108
203 - don't define our own MAXINT macro, it conflicts with windows header
204 files and in a few places it was the wrong value to use anyway.
205 https://rt.cpan.org/Ticket/Display.html?id=96425
207 Imager 0.99_01 - 29 Jun 2014
210 - GIF: add support for giflib 5.1.0, which added error code pointer
211 parameters to EGifCloseFile() and DGifCloseFile().
212 https://rt.cpan.org/Ticket/Display.html?id=96756
214 - GIF: avoid a double-free when do_write() fails.
216 - fix SV type probing to work on perl before 5.12. Broken in 0.99.
217 https://rt.cpan.org/Ticket/Display.html?id=96761
219 - PNG: skip the benign error test before libpng 1.6.0, since the
220 error we're testing didn't exist before 1.6.0.
221 https://rt.cpan.org/Ticket/Display.html?id=94717 (continued)
223 Imager 0.99 - 25 Jun 2014
226 - Imager::IO->new_buffer() (and hence Imager->read()'s data
227 parameter) now accepts a reference to a scalar as well as just a
229 https://rt.cpan.org/Ticket/Display.html?id=92785
231 - Imager::IO->new_buffer() now always makes a copy of the passed in
232 buffer to avoid problems with temporary objects used for the return
234 https://rt.cpan.org/Ticket/Display.html?id=92785
236 - improved the XS for i_io_read() and i_io_raw_read()
237 https://rt.cpan.org/Ticket/Display.html?id=92738
239 - load plugins from absolute paths on Android
240 Thanks to Brian Fraser.
241 https://rt.cpan.org/Ticket/Display.html?id=93272
243 - added the jpeg_optimize parameter for writing JPEG files. This can
244 significantly reduce file sizes, but uses more memory and time.
245 https://rt.cpan.org/Ticket/Display.html?id=94292
247 - the autolevels filter now works on the luminosity of the image
248 rather then working per channel. The old autolevels filter is
249 still available as "autolevels_skew".
250 https://rt.cpan.org/Ticket/Display.html?id=94413
252 - Imager::File::PNG now supports libpng 1.6.10.
253 1.6.10 changed CRC errors from benign errors to normal errors,
254 which broke the test which used CRC errors to check for benign
255 error support. Switched to using a 1-bit grey-scale image with a
256 palette to test for benign errors.
257 https://rt.cpan.org/Ticket/Display.html?id=94717
259 Imager 0.98 - 3 Jan 2014
262 Incompatible changes:
264 - the return value of setpixel() has changed.
266 Previously the return values for undrawable pixels vs caller errors
267 changed depending on whether you used the multiple pixel calling
268 mechanism, or the single pixel mechanism.
272 - for an invalid parameter, such as an unknown colour, or missing
273 parameter, an empty list (or undef in scalar context) is
274 returned, and errstr() is set,
276 - otherwise the number of pixels drawn is returned. If none of
277 the pixels could be drawn (they were all outside the image), "0
278 but true" is returned.
280 https://rt.cpan.org/Ticket/Display.html?id=87650
284 - when drawing on an image with an alpha channel where the source
285 minimum is greater than zero, Imager would read from beyond the end
286 of a malloc() allocated buffer. In rare circumstances this could
287 lead to some of the source image not being written to the target
288 image, or possibly to a segmentation fault.
289 I don't believe this has any security concerns beyond that.
291 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
292 text drawn would be nonsense. This would also read beyond the end
293 of a malloced buffer.
295 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
297 https://rt.cpan.org/Ticket/Display.html?id=88993
299 - Imager::Font::Wrap no longer requires the image parameter.
300 https://rt.cpan.org/Ticket/Display.html?id=87338
302 - a documentation typo fix in Imager::Transformations
303 Thanks to Adrian Yee.
304 https://rt.cpan.org/Ticket/Display.html?id=88598
306 - Image::Probe, Imager's internal module for probing library
307 locations now searches the directories specified by LD_RUN_PATH,
308 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
309 and the corresponing s/\blib$/include/ directories for header
311 https://rt.cpan.org/Ticket/Display.html?id=86428
313 Imager 0.97 - 15 Jul 2013
316 No changes from 0.96_02.
318 Imager 0.96_02 - 8 Jul 2013
321 - PNG: treat a version mismatch between headers and library as a
323 https://rt.cpan.org/Ticket/Display.html?id=86659
325 - PNG: the check for benign error support is more complex than a
326 simple library version check, check for the appropriate macro.
327 Thanks for Slaven Rezic for following up on my CPAN Testers result
329 https://rt.cpan.org/Ticket/Display.html?id=86659
331 - W32: add a missing head1 AUTHORS to the old Win32.pm
332 https://rt.cpan.org/Ticket/Display.html?id=86658
334 Imager 0.96_01 - 1 Jul 2013
337 - TIFF: handle SampleFormat = 2 by translating the signed integer
338 values to unsigned by flipping their sign bits.
340 Handle SampleFormat = 3 where possible.
342 SampleFormat is ignored for paletted images.
344 Mixed SampleFormat are handled incorrectly, since libtiff returns
345 only the first SampleFormat value, and an image with both an alpha
346 channel and SampleFormat = 2 for color channels probably has a
347 different SampleFormat for the alpha channel.
349 https://rt.cpan.org/Ticket/Display.html?id=74540
352 https://rt.cpan.org/Ticket/Display.html?id=69243
354 - Imager::Color's rgba() method now returns its values as integers
355 instead of floating point. (IV instead of NV).
357 - The XS for i_map() and i_matrix_transform() now use the AV *
358 typemap instead of rolling their own.
360 - The XS for DSO_call() now uses the HV * typemap instead of
363 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
364 i_gradgen() now use a new T_AVARRAY typemap that greatly
365 simplifies the XS code.
367 - many other minor XS changes
369 - some XS code formatting
371 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
372 now renders in alpha-combining mode, to match antialiased output.
373 https://rt.cpan.org/Ticket/Display.html?id=73359
375 - add sample code and cookbook notes for drawing a blurred drop-shadow.
377 - add support for libpng 1.6, which changed the defaults for
378 reporting some types of error.
379 https://rt.cpan.org/Ticket/Display.html?id=85746
381 - FT2: use gsamp/psamp() to transfer pixels from the work image to
382 the output image instead of gpix/ppix.
383 https://rt.cpan.org/Ticket/Display.html?id=83478
385 - eliminate various GCC warnings, mostly initialized but otherwise
388 Imager 0.96 - 19 May 2013
391 - rearrange Imager's test files.
392 https://rt.cpan.org/Ticket/Display.html?id=84596
394 - Imager::Probe::_gcc_lib_paths now forces C locale.
395 A sufficiently recent gcc prints localized keys for the search
396 paths, which avoids that localization.
397 https://rt.cpan.org/Ticket/Display.html?id=84963
399 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
400 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
402 https://rt.cpan.org/Ticket/Display.html?id=85262
403 reported by Andreas König
405 - add a test for unclosed POD in C source, and fix the errors it
407 https://rt.cpan.org/Ticket/Display.html?id=74875
409 - fix some spelling errors detected by the newer aspell in Debian
412 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
413 thanks to gregor herrmann <gregoa@debian.org>
414 https://rt.cpan.org/Ticket/Display.html?id=85413
416 - add a test for standard =head1 commands and fix the errors found
418 Imager 0.95 - 19 Apr 2013
421 - handle the SVf_UTF8 flag correctly on magic strings passed to
422 Imager::IO's write() and raw_write() methods.
423 This may misbehave in perl 5.6.x since the UTF8 flag may not be
424 visible in the main SV after SvGETMAGIC().
425 https://rt.cpan.org/Ticket/Display.html?id=83438
427 - document that bounding_box() ignores the transformation matrix
428 supplied to tranform() for fonts.
429 https://rt.cpan.org/Ticket/Display.html?id=84106
431 Imager 0.94_02 - 5 Apr 2013
434 - enable debug logging for the standard font tests
436 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
437 due to a bug in that version of perl.
439 - don't test for read() failing on a write-only handle in 5.8.x and
440 earlier, this was fixed in change 862083f7e4 in perl.
442 - report the version of Inline found during testing (an attempt to
443 diagnose some intermittent failures.)
445 Imager 0.94_01 - 2 Mar 2013
448 - NOTE: possibly backward incompatible:
449 support reading from/writing to perl filehandes that aren't raw
452 This allows Imager's I/O to honour handles with layers such as
453 gzip, scalar file handles or tied file handles.
455 This is backward incompatible in that previous Imager would simply
456 use fileno() to retrieve the fd for the file and call write(2) etc
458 https://rt.cpan.org/Ticket/Display.html?id=78843
460 - moved most of README to lib/Imager/Install.pod which should make it
461 more accessible to the "web" generation, also significantly updated
464 - updated README's for the separately distributed modules to refer to
465 Imager::Install, and that they need -dev versions of packages
466 https://rt.cpan.org/Ticket/Display.html?id=81265
468 - the JPEG test code now reports the compile-time library version
470 - avoid a possible compiler optimization issue on CentOS 5.9 i386 by
471 rearranging (and mildly optimizing) some code.
472 https://rt.cpan.org/Ticket/Display.html?id=83212
474 - fix a POD error in Imager::Fill (detected on new Pod-Simple)
475 https://rt.cpan.org/Ticket/Display.html?id=83434
477 - fix a broken link to Graphics::Magick
478 https://rt.cpan.org/Ticket/Display.html?id=82743
480 - drawing text to a channel with FT2 would draw with random coverage
481 due to an uninitialized alpha channel.
483 - marked the function pointer underlying the mm_log() API with the
484 correct gcc magic and fixed the resulting warnings.
486 - fixed some other compiler warnings
488 - Imager::Font::W32 now properly reports text drawing errors
489 https://rt.cpan.org/Ticket/Display.html?id=70098
491 - handle the SVf_UTF8 flag correctly on magic (eg. overloaded)
492 strings passed as text to draw(), bounding_box(), has_chars(),
493 glyph_names() (where supported) in each of the font drivers.
494 This may misbehave in perl 5.6.x since the UTF8 flag may not be
495 visible in the main SV after SvGETMAGIC().
496 https://rt.cpan.org/Ticket/Display.html?id=83438 (partial)
498 Imager 0.94 - 15 Dec 2012
499 =========================
501 Variations on some of these changes were included in development
504 - improved thread safety
505 - the internal error stack and log file handle are now in a per-thread
507 - JPEG now captures IPTC information in a thread-safe way
508 - avoid globals where possible for warning capture in libtiff
509 - use a mutex to avoid re-entering thread-unsafe giflib
510 - use a mutex to avoid re-entering thread-unsafe tifflib
511 - use a mutex to avoid re-entering thread-unsafe T1Lib
512 - use a library handle per thread for freetype 2.
513 - use an engine handle per thread for freetype 1.x.
514 - originally these changes broke ABI compatibility, this has been
517 - clarify the return value of getpixel();
518 https://rt.cpan.org/Ticket/Display.html?id=81198
520 - fixed a race condition in parallel testing for T1
522 - fixed a bug in handling yoff for untransformed image-based fills
524 - documentation improvements for Imager::Fill
526 - FT2: report the library version while testing.
528 Imager 0.93 - 15 Oct 2012
533 - previously a transparency enabled GIF write (the default) would
534 always use a GIF89a header even if none of the images were
537 - previously the probe step for freetype-config would fail on cygwin
539 - catch an invalid matrix parameter to convert() instead of crashing
540 https://rt.cpan.org/Ticket/Display.html?id=79922
542 - remove the 16-bit/sample limitation from the documentation for
543 setsamples(), it hasn't applied for many releases.
544 https://rt.cpan.org/Ticket/Display.html?id=79989
546 - don't copy setsamples() data parameter, it may be a large scalar
547 https://rt.cpan.org/Ticket/Display.html?id=79990
549 - clean up .dSYM directories generated performing probes on OS X
552 - pass the --verbose command-line option through to Imager::Probe in
553 sub-module's Makefile.PLs
554 https://rt.cpan.org/Ticket/Display.html?id=75878
558 - support for giflib 5.0. (5.0.1 and later)
559 https://rt.cpan.org/Ticket/Display.html?id=79029
560 The giflib API Imager uses doesn't have a mechanism to set the
561 header version in 5.0.0.
563 - update the GIF library probe code to check for the new giflib 5.0.1
564 EGifSetGifVersion() function, and to check for the giflib 4.2.0
565 uninitialized gif89 bug.
566 https://rt.cpan.org/Ticket/Display.html?id=79679
567 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
569 - avoid static variables when capturing IPTC data from JPEG files
571 - match Imager::Font;:T1's error message translations to those from
572 later versions of T1Lib.
574 - for libtiff versions that support extended warning handlers (3.8.0
575 or later), use them to avoid some global variables.
577 - note Image::ExifTool for better metadata support.
578 https://rt.cpan.org/Ticket/Display.html?id=79251
580 Imager 0.92 - 14 Aug 2012
583 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
584 correctly for both probing and runtime.
585 https://rt.cpan.org/Ticket/Display.html?id=77672
587 - allow building JPEG/imexif.c on C89 compilers.
589 - allow building GIF/imgif.c on C89 compilers.
591 Imager 0.91 - 4 Jun 2012
596 - The size of rotated images is no longer rounded up so aggressively.
597 Added rounding to the linear interpolation done for rotate() and
598 matrix_transform() for 1 and 3 channel 8-bit images.
599 Adjusted the two tranlate matrices used to build the final rotation
600 matrix to use the distance between the outlier pixels rather than
601 the pixel dimensions (ie. dimension-1).
602 With all of this the output of rotate(degrees => 270) on an 8-bit
603 image exactly matches the output of rotate(right => 270).
604 https://rt.cpan.org/Ticket/Display.html?id=77063
608 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
609 internals, those names only matter for the XS interface.
611 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
612 the API level compiled into a loadable module such as
613 Imager::File::GIF doesn't match that of Imager. Previously it
614 could be difficult to determine exactly which module was failing to
616 https://rt.cpan.org/Ticket/Display.html?id=77173
618 - added Imager->check_file_limits() as an interface to the
619 i_int_check_image_file_limits() API.
621 - Imager->set_file_limits(reset => 1) now resets the limits to the
622 defaults rather than setting them all to unlimited.
624 - wrote a brief security note as Imager::Security

627 Imager 0.90 - 30 Apr 2012
632 - Imager::Test::is_imaged() attempted to process an "epsilon"
633 parameter but the prototype didn't allow for the extra parameter.
634 Corrected the prototype.
636 - when downconverting samples (eg. from floating point to 8 bit)
637 Imager now rounds the sample value rather than attempting to
638 allocate input values over output values equally. The old
639 behaviour had the probably surprising effect of converting a
640 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
642 This may result in slightly different 8 or 16-bit output images.
644 - BI_BITFIELD BMP images were handled incorrectly, both in
645 incorrectly calculating the space required for the masks and in
646 processing the image data itself.
647 https://rt.cpan.org/Ticket/Display.html?id=76736
649 - some odd width BMP BI_RLE4 images use run lengths that run one off
650 the edge of the image. Imager now allows this, discarding the
653 - odd length RLE4 runs in BMP images were decoded incorrectly.
655 - pkg-config could sometimes return a library that was in a directory
656 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
657 If no -L is included in the pkg-config library information check if
658 EU::MM can find the library, and if not, search our configured
659 directories and insert that into the library flags.
660 https://rt.cpan.org/Ticket/Display.html?id=75869
662 - Imager::Probe can now probe for libraries with dependent libraries,
663 common for static linking, eg. libpng requires libz.
664 https://rt.cpan.org/Ticket/Display.html?id=74043
666 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
668 - added alternative probe configurations that try to link libz, to
669 handle a statically linked libpng.
670 https://rt.cpan.org/Ticket/Display.html?id=74043
672 - if a probe includes testcode, Imager::Probe now checks that code as
673 part of the process of checking each configuration rather than as a
674 post test of the found configuration. This allows alternate
675 configurations to be checked if a matching but non-working
676 configuration is found.
677 https://rt.cpan.org/Ticket/Display.html?id=74043
681 - when reading or writing images via callbacks, the default callbacks
682 now push an error message indicating that a required callback was
683 called but not supplied.
684 https://rt.cpan.org/Ticket/Display.html?id=76782
686 - clarify which callbacks are required for reading and writing TIFF
689 - improve logging for creation of callback I/O layers.
691 - a little more documentation for Imager::Probe.
693 - the i_get_file_background() and i_get_file_backgroundf() APIs now
694 return int to indicate whether the i_background tag was found.
697 - improve error reporting
698 - add png_interlace, png_bits tags
699 - read paletted images as paletted images, including transparency
700 - read 1 bit greyscale images as a type suitable for other file
701 handlers to write as bilevel
702 - read 16 bit/sample PNG as 16-bit/sample Imager images
703 - write "bilevel" paletted images as 1 bit grayscale images
704 - write paletted images as paletted images
705 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
707 - improved metadata support
708 https://rt.cpan.org/Ticket/Display.html?id=29268
710 Imager 0.89 - 18 Mar 2012
715 - getpixel(..., type => "float") and the API i_gpixf() have been
716 broken on paletted images since they were implemented.
717 https://rt.cpan.org/Ticket/Display.html?id=75258
721 - links in the METHOD INDEX now point at the method documentation
722 rather than the heading you can find them under.
723 https://rt.cpan.org/Ticket/Display.html?id=71495
725 - Imager (and the bundled dynamic modules) no longer fallback to
726 using DynaLoader if loading via XSLoader fails.
727 For the bundled modules this could hide useful error messages.
728 https://rt.cpan.org/Ticket/Display.html?id=75560
730 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
731 buffer in the array of allocations, but just stores the filename
732 pointer and line number.
733 https://rt.cpan.org/Ticket/Display.html?id=70388
735 Imager 0.88 - 22 Feb 2012
738 - describe how to build libgif etc on OS X in such a way as to be
739 compatible with a fat binary perl (such as the system perl), in
741 https://rt.cpan.org/Ticket/Display.html?id=73371
743 - update the change notes for 0.77_01 to indicate that libungif
746 - add some other imaging modules to SEE ALSO
747 https://rt.cpan.org/Ticket/Display.html?id=73906
749 - note that the generator of the apparently non-DFSG-free postscript
750 in MMOne.pfb is a Debian package.
752 - setsamples() is now a true complement to getsamples() - it can
753 write 8-bit or floating point samples from a scalar or array
754 reference. This adds i_psamp() and i_psampf() to the C level API.
756 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
757 changed to make better use of the typemap, but these aren't part of
758 the perl level API anyway. There were no changes to the C level
759 interfaces to these functions.
761 - getpixel() and setpixel() now accept a mix of scalar and array
762 references for the x and y parameters, and unequal array lengths is
764 https://rt.cpan.org/Ticket/Display.html?id=73697
768 - correctly calculate the size of a rotated image
769 https://rt.cpan.org/Ticket/Display.html?id=69261
771 - fix incorrect rounding of color values for matrix_transform() and
773 https://rt.cpan.org/Ticket/Display.html?id=69261
775 - Win32 text output is now done in normal combine mode, the alpha
776 component of the color is now significant.
777 https://rt.cpan.org/Ticket/Display.html?id=70014
779 - remove long unused gif case from read()
780 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
782 - the getsamples() target parameter was being treated as a hashref
783 when it's meant to be an array reference.
784 https://rt.cpan.org/Ticket/Display.html?id=74882
786 - getpixel() and setpixel() now returns an empty list when invalid
787 parameters are supplied.
788 Invalid values for type now result in an error for getpixel().
789 https://rt.cpan.org/Ticket/Display.html?id=73697
791 Imager 0.87 - 03 Jan 2012
794 - document the return value of the filter() method.
795 https://rt.cpan.org/Ticket/Display.html?id=72369
797 - document i_gsamp_bits() and i_psamp_bits().
798 https://rt.cpan.org/Ticket/Display.html?id=68815
800 - properly increment the Imager::Matrix2d $VERSION.
802 - actually include the Imager::Test tests in the dist
804 - correctly read and write 256x256 pixel ICO files
805 https://rt.cpan.org/Ticket/Display.html?id=69599
807 - make the error message from read() or read_multi() when they can't
808 identify the file type match reality.
809 https://rt.cpan.org/Ticket/Display.html?id=72475
811 - read() now uses $FORMATGUESS if it can't determine the file type
812 based on the file header, to match read_multi().
814 - re-work and add tests for def_guess_type(). def_guess_type() no
815 longer returns any random file extension as the file type.
817 - add gray4, gray16 and gray as presets for make_colors.
818 https://rt.cpan.org/Ticket/Display.html?id=67911
820 - add make_palette() method that produces a palette from one or more
823 - fix the Imager dependency for the separately distributed font
825 https://rt.cpan.org/Ticket/Display.html?id=72643
827 - fix i_render_color() to properly draw in "normal" mode - ie. when
828 writing to a 1 or 3 channel image the second or fourth channel of
829 the source color was being ignored, it is now significant.
830 https://rt.cpan.org/Ticket/Display.html?id=71564
832 Imager 0.86 - 31 Oct 2011
835 - improve error reporting for W32 tests
837 Imager 0.85_02 - 24 Oct 2011
842 - eliminate unused i_gif_opts type (clean-up)
843 https://rt.cpan.org/Ticket/Display.html?id=69245
845 - fix combine=0 fill color anti-aliasing on the double/sample path
846 https://rt.cpan.org/Ticket/Display.html?id=71309
848 - make default text color non-transparent
849 https://rt.cpan.org/Ticket/Display.html?id=71469
851 - apply the last of the Debian unforwarded spelling fixes
852 https://rt.cpan.org/Ticket/Display.html?id=70656
854 - the log() method used its message parameter as a C level format
856 https://rt.cpan.org/Ticket/Display.html?id=71653
858 - provide our own STRLEN typemap entry for older perls.
859 https://rt.cpan.org/Ticket/Display.html?id=71641
861 - add extra ppport.h configuration to support older perls.
863 - depend on Scalar::Util, since we use it and older perls don't have
866 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
867 to synthesize it from overloaded "".
869 - use T1_StrError() for error messages on modern libt1
870 https://rt.cpan.org/Ticket/Display.html?id=69879
872 - actually load the font rather than just adding it to the catalog on
875 - Imager::Font->new now produces better error messages for the T1
878 - the font has_chars() method now returns perl's true and false
879 values in list context rather than integers, which should be more
881 https://rt.cpan.org/Ticket/Display.html?id=69158
883 - the btm data structure used by the flood_fill code is now
884 initialized more efficiently.
885 https://rt.cpan.org/Ticket/Display.html?id=68994
887 - updated the Thanks list in README
888 https://rt.cpan.org/Ticket/Display.html?id=71607
890 - check there's at least one coefficient for the convolution filter
891 https://rt.cpan.org/Ticket/Display.html?id=68993
893 - make the APIRef synopsis ordering consistent, older versions of
894 perl could order it differently.
895 https://rt.cpan.org/Ticket/Display.html?id=71675
897 - we rely on Config.pm's d_vsnprintf as to whether we use
898 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
899 though it only has _ prefixed versions of these. Define our own
900 prefixed names on Win32.
901 https://rt.cpan.org/Ticket/Display.html?id=71642
903 - fix library detection with MSVC
905 - search a few more library directories, so EU::MM doesn't discard
906 them. Hopefully fixes:
907 https://rt.cpan.org/Ticket/Display.html?id=71643
909 Imager 0.85_01 - 10 Oct 2011
912 - add simple tests for the Imager::Test test_image generators
914 - io_glue I/O buffering re-work:
916 - reorganize io_glue to do it's own buffering by default
918 - the unbuffered functions are available as i_io_raw_read() (or
919 raw_read() from perl) etc but are not recommended for typical
922 - use the new i_io_peekn() when checking for file magic to avoid
923 seek, allowing Imager to detect the file type and read the file
924 from an unseekable stream (for formats that don't use random
927 - added several new I/O layer API functions.
929 - fix the TGA performance problem, most noticably on Win32
930 https://rt.cpan.org/Ticket/Display.html?id=70037
932 - TIFF now uses wrapper functions of the correct types to avoid casts
933 https://rt.cpan.org/Ticket/Display.html?id=69912
935 - the callback IO object did its own buffering, controlled by the
936 maxbuffer parameter supplied to the read() and write() methods.
937 This buffering has been removed, to avoid redundancy with the
938 common io_glue buffering. This also avoids a bug in that code
939 which could rarely pass a zero length to the read callback and
940 then panic about the result.
942 - the callback IO object now tests the result of calling the close
943 callback, which should return true for success.
945 - the PNM reader did its own buffering. This buffering has been
946 removed to avoid redundancy with the common io_glue buffering.
948 - previously the read handlers for fd and callback I/O layers would
949 call the underlying interface (POSIX read or your supplied callback)
950 until it filled the buffer. It now only makes one call.
952 - added public constructors for I/O layer objects (see Imager::IO)
954 - all core file handlers now use the i_io_foo() wrappers to gain
955 access to buffered I/O rather than calling the I/O layer
958 - all core file handlers now check for error on close.
960 - Backward compatibility: if you hava custom file handlers, you can
961 use i_io_write() etc since they're available as macros in older
964 - eliminate the final remnants of io_glue_commit_types().
966 - bump IMAGER_API_VERSION, since the above may break assumptions.
968 - removed the long unused i_gen_reader() and i_gen_writer() utility
971 Imager 0.85 - 29 Aug 2011
974 The main changes in the release versus 0.84 are:
976 - on 64-bit systems, 64-bit types are consistently used for image
977 dimensions and co-ordinated, and for memory block sizes.
979 - handle IFD loops in TIFF files correctly. Previously this would
980 lead to an infinite loop.
984 - fix the link in the getheight() entry in the method index
986 Imager 0.84_02 - 22 Aug 2011
989 Development release, this will become 0.85 if CPAN testers is
994 - the image file limits set by set_file_limits() weren't being
995 checked when reading TIFF files.
996 https://rt.cpan.org/Ticket/Display.html?id=69915
998 - Provide more information about file format module load errors on a
999 failed image file read() or write().
1000 https://rt.cpan.org/Ticket/Display.html?id=69194
1002 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
1003 through TIFF images, since it checks for IFD loops.
1004 https://rt.cpan.org/Ticket/Display.html?id=69914
1006 - don't leak memory when out of range palette indexes are supplied to
1008 https://rt.cpan.org/Ticket/Display.html?id=69242
1010 - require a later version of CPAN::Meta to ensure JSON::PP and
1011 CPAN::Meta::YAML are available.
1012 https://rt.cpan.org/Ticket/Display.html?id=69008
1014 - hoist the per-line calculations for the flines implementations, and
1015 modernize the tests a bit.
1016 https://rt.cpan.org/Ticket/Display.html?id=70126
1018 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
1019 them when available.
1020 https://rt.cpan.org/Ticket/Display.html?id=69147
1022 - if t1lib failed to reinitialize it would be left as marked
1024 https://rt.cpan.org/Ticket/Display.html?id=69877
1026 - update the bundled (and still modified) Devel::CheckLib
1027 https://rt.cpan.org/Ticket/Display.html?id=69170
1029 Imager 0.84_01 - 8 Aug 2011
1032 Development release as a sanity check for the types re-work.
1034 Massive types re-work:
1036 - the type used internally for pixel co-ordinates and image sizes is
1037 now 64-bit on 64-bit platforms (at least sane ones).
1039 - size_t is now used consistently for memory block sizes.
1041 - since this changes the binary interface, the Imager API version has
1042 been incremented. Any module that uses the API will need to be
1043 rebuilt. In most cases that will be enough, but calls to any APIs
1044 that take a pointer to image sizes may need source changes.
1046 - you should be able to create very large images on 64-bit systems,
1047 if you have enough memory. Successfully created a 32768 x 49192 x
1048 3 channel image, filled with a tiled image and scaled it. The
1049 unscaled image was also successfully saved to a JPEG.
1051 - check the image size before attempting to write BMP, GIF, JPEG,
1052 PNG, SGI, TGA, TIFF images.
1054 - correctly handle reading TGA images over 32767 pixels wide or tall.
1058 - the gif_left and gif_top tags are now clamped to non-negative
1059 values when writing a GIF image.
1061 - removed dead callback read/write code
1063 The default maximum memory size when reading files is now 1G.
1065 Imager 0.84 - 20 Jun 2011
1068 - Imager no longer inherits from Exporter (unless you're running an
1071 - Imager can now write progressive JPEGs (it could always read them).
1072 https://rt.cpan.org/Ticket/Display.html?id=68691
1076 - re-work, document and test Imager's logging facility.
1077 https://rt.cpan.org/Ticket/Display.html?id=65227
1079 - fix META.yml testing and the generated META.yml
1080 https://rt.cpan.org/Ticket/Display.html?id=65235
1082 - test and add error reporting to to_*() family methods
1084 - add to_rgb_double() method.
1085 https://rt.cpan.org/Ticket/Display.html?id=65101
1087 - Imager no longer exports anything by default
1088 https://rt.cpan.org/Ticket/Display.html?id=65228
1090 - convert colors to grayscale if the supplied (or generated) palette
1091 contains only grays when performing error diffusion color
1093 https://rt.cpan.org/Ticket/Display.html?id=68508
1095 - writing a paletted image to GIF wouldn't always use the colors
1096 supplied (or generated, eg. via make_colors => "mono"), which was
1098 https://rt.cpan.org/Ticket/Display.html?id=67912
1100 - replace (imager|tony)@imager.perl.org in the doc, since I don't
1101 plan to continue receiving mail at that address.
1102 https://rt.cpan.org/Ticket/Display.html?id=68591
1104 Imager 0.83 - 21 May 2011
1109 - diag() the error message on failure for some TIFF tests that are
1110 failing on a Solaris smoker.
1111 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
1113 Imager 0.82_01 - 17 May 2011
1116 Dev release, in case the compose tests are too sensitive.
1120 - Imager::Font::T1 incorrectly checked for absolute filename under
1121 Win32. Thanks to kmx for the report and fix.
1122 https://rt.cpan.org/Ticket/Display.html?id=67963
1124 - compose() with the target, source or mask position off the top or
1125 left of the target image didn't clip the source image correctly.
1126 https://rt.cpan.org/Ticket/Display.html?id=67220
1128 - compose() now returns a useful error message on a non-positive
1131 - compose.im now at 100% test coverage. (As opposed to, umm, much,
1134 Imager 0.82 - 14 Mar 2011
1139 - eliminate calls to i_has_format() from the test suite, since it's
1140 no longer a useful way to check for file format support. Eliminate
1141 i_has_format() from the functions exposed via XS.
1142 https://rt.cpan.org/Ticket/Display.html?id=65863
1144 - eliminate calls to note(), which isn't in the (very old) version of
1145 Test::More we have as a pre-requisite. note() is modern enough
1146 that I don't feel a need to require a Test::More upgrade for it.
1147 https://rt.cpan.org/Ticket/Display.html?id=65864
1149 - skip the threads tests on Test::More 2.00_*
1150 https://rt.cpan.org/Ticket/Display.html?id=65812
1152 - add an (unshipped) test to check Imager's internal POD links
1153 https://rt.cpan.org/Ticket/Display.html?id=65749
1155 - improve the library detection summary
1156 https://rt.cpan.org/Ticket/Display.html?id=9675
1158 - increase the version of Imager::Font::Type1 so that upgrades don't
1159 downgrade the version in this file.
1160 https://rt.cpan.org/Ticket/Display.html?id=66250
1162 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
1163 that option for the directories that would normally go in
1164 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
1165 https://rt.cpan.org/Ticket/Display.html?id=65955
1167 Imager 0.81 - 14 Feb 2011
1170 - added coverage tests for masked images (maskimg.c @100% test coverage)
1172 - add hsv() method to Imager::Color
1173 Thanks to Leolo (Philip Gwyn)
1174 https://rt.cpan.org/Ticket/Display.html?id=65385
1176 - split libt1 Type 1 font support into a sub-module
1177 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1179 - add a preload() class method for use in forking servers, and to
1180 work around limitations in PAR.
1181 https://rt.cpan.org/Ticket/Display.html?id=65665
1185 - paletted writes to a masked image are now masked correctly.
1186 Revealed by new coverage tests.
1188 - update the filter plugin documentation.
1189 https://rt.cpan.org/Ticket/Display.html?id=56513
1191 - add the matrix() method to Imager::Matrix2d to allow creation of a
1192 matrix with specified co-efficients. You can now multiple an
1193 Imager::Matrix2d object by a 9 element array ref or a number.
1194 https://rt.cpan.org/Ticket/Display.html?id=29938
1196 - really fix loading TTF fonts with FT2 when FT1 isn't available.
1197 Thanks to Leolo (Philip Gwyn)
1198 https://rt.cpan.org/Ticket/Display.html?id=65386
1199 https://rt.cpan.org/Ticket/Display.html?id=62855
1201 - make sure each test script that needs testout/ creates it.
1202 https://rt.cpan.org/Ticket/Display.html?id=65088
1204 - handle a slightly different warning from libtiff 4.x
1205 https://rt.cpan.org/Ticket/Display.html?id=65268
1207 - the sat transform2() op returned an incorrect saturation.
1208 https://rt.cpan.org/Ticket/Display.html?id=65391
1210 Imager 0.80 - 17 Jan 2011
1213 - added coverage tests for Imager::Fountain and Imager::Color::Float
1215 - Imager is now maintained in git
1216 http://git.imager.perl.org/imager.git
1217 git://git.imager.perl.org/imager.git
1221 - images with an translucent alpha channel were not scaled correctly
1222 by the default (qtype=normal) scaling method.
1223 https://rt.cpan.org/Public/Bug/Display.html?id=63922
1225 - Imager::Color::Float now translates "#FFFFFF" to white instead of
1226 just a little darker.
1228 - make the default color map build algorithm "mediancut". This
1229 changes the default color map builder for writing GIFs back to what
1230 it was in 0.77, reverting a performance regression.
1231 https://rt.cpan.org/Ticket/Display.html?id=64785
1233 - handle failure to create a masked image correctly
1235 Imager 0.79 - 10 Dec 2010
1238 - add Imager::Test to the POD coverage tests and document the missing
1241 - the convert() method now optimizes the case where all output
1242 channels are either 0, sourced from a single input channel or 1.
1243 This significantly speeds up presets like "addalpha", "green".
1244 https://rt.cpan.org/Ticket/Display.html?id=51254
1246 - add wiggle.pl sample, as suggested by Dan Oppenheim.
1248 - add the combine() method to combine channels from multiple source
1249 images into a new image
1250 https://rt.cpan.org/Ticket/Display.html?id=11872
1254 - treat the co-efficients for convert() as doubles instead of floats.
1256 - If a higher (earlier) priority font handler failed to load, that
1257 would crash preventing loading of later font handlers.
1258 https://rt.cpan.org/Ticket/Display.html?id=62855
1260 - parse defines from the options returned by pkg-config --cflags
1261 https://rt.cpan.org/Ticket/Display.html?id=63223
1263 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
1264 included in the tarball. They are now included.
1266 Imager 0.78 - 4 Oct 2010
1271 - don't access deprecated members of the png_structp.
1272 https://rt.cpan.org/Ticket/Display.html?id=60242
1274 - document that using color objects is faster than supplying colors
1276 https://rt.cpan.org/Ticket/Display.html?id=61047
1278 - Imager::Probe now accepts array references for incpath and libpath.
1279 https://rt.cpan.org/Ticket/Display.html?id=60244
1281 Imager 0.77_02 - 27 Sep 2010
1284 - moved Win32, FreeType 2 font support into sub-modules.
1285 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1286 Uses Imager::Probe now.
1287 https://rt.cpan.org/Public/Bug/Display.html?id=61328
1289 - tested successfully with jpeg-8b
1290 https://rt.cpan.org/Ticket/Display.html?id=60221
1294 - from _01: look for missing file support test files in the right
1297 - flood_fill() wouldn't fill the right side of a single scan-line
1299 Thanks to Nicolas Roggli for reporting this.
1301 - flood_fill wouldn't fill to the left edge of the image if the
1302 starting line didn't reach the left edge.
1303 Thanks to Nicolas Roggli for reporting this.
1305 Imager 0.77_01 - 13 Sep 2010
1308 - add each library-directory/pkgconfig/ to the pkg-config search path
1310 Thanks to Justin Davis.
1311 https://rt.cpan.org/Ticket/Display.html?id=60491
1313 - moved GIF, TIFF, JPEG file handling code into sub-modules in
1314 preparation for separate distribution.
1315 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1317 Note: this removed support for libungif from Imager.
1319 - optimize filled box drawing (color, not fill)
1323 - Imager::Probe was calling ExtUtils::Liblist to initialize
1324 LD_RUN_PATH supplying an undefined value rather than the found
1325 directory. Thanks to Justin Davis.
1326 https://rt.cpan.org/Ticket/Display.html?id=60491
1328 - only prepend ./ to font filenames when passing them to T1Lib and
1329 then only when it would use its search mechanisms.
1330 https://rt.cpan.org/Ticket/Display.html?id=60509
1332 - fix the cache check for the X rgb.txt loader. This is typically
1333 used for color translation on Unix-like systems, and the fix
1334 improves performance of supplying colors by name by about 80 times.
1335 Test code that managed 3400 10x10 pixel boxes/second sped up to
1338 - clarify that Imager doesn't write EXIF metadata to images.
1339 https://rt.cpan.org/Ticket/Display.html?id=60637
1341 - Imager::Probe can now search subdirectories under its include path.
1342 Used by the PNG Makefile.PL to find headers and libraries when they
1343 aren't in the base directory, as in cygwin.
1344 https://rt.cpan.org/Ticket/Display.html?id=60635
1346 Imager 0.77 - 11 Aug 2010
1349 I don't want Imager::File::PNG indexed as part of Imager, but forgot
1350 to update the META.yml before updating the version.
1352 - don't index Imager::File::PNG as part of Imager
1354 - add resources to META.yml
1356 Imager 0.76 - not released
1361 - the align_string() method would ignore a string of "0" due to a
1362 mis-use of C< ||= >.
1363 Thanks to Maurice Height for reporting this.
1364 https://rt.cpan.org/Ticket/Display.html?id=60199
1366 Imager 0.75_03 - 09 Aug 2010
1371 - read_types() and write_types() would include png when it wasn't
1372 available due to a problem with the %formats tie
1374 - handle dependent libraries correctly (eg -lpng requiring -lz) in
1375 the code run phase of library probing.
1377 Imager 0.75_02 - 07 Aug 2010
1382 - add file missing from MANIFEST, which was causing TIFF failures.
1384 Imager 0.75_01 - 06 Aug 2010
1387 Test release for the new PNG probe.
1389 - added the ability to read multiple-image PNM files.
1390 Note that unlike the pbm/pgm/ppm specification this accepts mixed
1391 format files and allows white space padding between files.
1392 Thanks to Philip Gwyn (Leolo) for this patch.
1394 - moved the PNG file handling code into a sub-module in preparation
1395 for separate distribution.
1396 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1397 Also helps avoid complications from -I/-L compile/link options from
1402 - Imager->new(data => $data) didn't try to process image file data in
1404 https://rt.cpan.org/Ticket/Display.html?id=58761
1406 - t/t50basicoo.t no longer depends on the other tests to generate its
1408 https://rt.cpan.org/Ticket/Display.html?id=9798
1409 Also, it wasn't testing pnm (pnm vs ppm mix-up)
1411 - update the documentation of hardinvert to match the change in 0.62.
1412 https://rt.cpan.org/Ticket/Display.html?id=59785
1414 - added hardinvertall filter which also inverts the alpha channel
1415 (sorry for the mess)
1417 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
1418 the probe can find the library for the test run.
1419 https://rt.cpan.org/Ticket/Display.html?id=57518
1421 Imager 0.75 - 20 Jun 2010
1424 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
1425 perls (not measured)
1429 - an opacity fill based on a fountain fill would segfault when
1430 filling an 8-bit/sample image.
1432 - merge thickline branch polygon fix
1433 https://rt.cpan.org/Ticket/Display.html?id=43518
1435 Imager 0.74 - 7 May 2010
1440 - read_multi() didn't handle a missing file format library correctly,
1441 aborting on failing to call i_readgif_multi_wiol() or
1442 i_readtiff_multi_wiol().
1444 - fix spelling errors patched by Debian
1445 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
1447 - add an (unshipped) author test to spellcheck Imager's POD.
1449 - update the TIFF file format documentation
1450 https://rt.cpan.org/Ticket/Display.html?id=56510
1452 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
1454 Imager 0.73 - 15 Mar 2010
1457 - implement outline circles, both anti-aliased and not
1458 https://rt.cpan.org/Ticket/Display.html?id=19755
1460 - a combine => "none" fill to a 1 or 3 channel image would produce
1461 the incorrect colour.
1463 Imager 0.72 - 09 Dec 2009
1466 Bump version for release, since 0.71_03 is stable with CPAN testers.
1468 Imager 0.71_03 - 5 Dec 2009
1471 - further adjust the threads test so it only performs the tests on
1472 perls where it's expected to work, and only if the threads module
1475 Imager 0.71_02 - 1 Dec 2009
1478 - adjust the way we load the threads module for the threads test so
1479 it works with non-threaded perls
1481 Imager 0.71_01 - 30 Nov 2009
1486 - use scanline oriented operations to flip images instead of pixel
1488 https://rt.cpan.org/Ticket/Display.html?id=39278
1490 - use double/sample operations to flip large sample images instead of
1491 8-bit sample operations.
1492 https://rt.cpan.org/Ticket/Display.html?id=39280
1495 https://rt.cpan.org/Ticket/Display.html?id=51874
1497 - prevent double-frees when someone creates Imager objects and then
1498 creates a thread. Note: this just handles some simple cases,
1499 Imager doesn't support perl threads, and isn't likely to.
1500 https://rt.cpan.org/Ticket/Display.html?id=52268
1502 Imager 0.71 - 16 Nov 2009
1505 - add the opacity fill type - an adaptor that modifies the opacity of
1510 - the conv filter now enforces that the sum of the coefficients is
1511 non-zero. Also, rather than skipping pixels off the edge off the
1512 edge of the image, the closest edge pixel is used. Previously
1513 dividing by the zero sum of coefficients could cause invalid
1514 results or runtime exceptions.
1515 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
1518 Imager 0.70 - 21 Sep 2009
1523 - release image row and comments memory on all error returns in gif
1526 - handle zero length extensions, previously this would cause a null
1528 Thanks to Krzysztof Wojtaś for the test data and fix for this.
1530 - an integer division meant that preview scaling to below 1 pixel
1531 wide or high (which isn't too useful anyway) was calculating using
1532 NaNs on most platforms, and causing an exception on others.
1533 Thanks to David Cantrell for producing a backtrace of the crash on
1534 his Alpha-NetBSD CPAN test box which made it possible to track this
1537 Imager 0.69 - 08 Sep 2009
1542 - broken test fix - was attempting to call a function skip_all, when
1543 that should be a parameter to plan().
1545 - briefly document apidocs.perl, the tool used to build
1546 Imager::APIRef and make some minor enhancements
1548 - various minor documentation enhancements and fixes.
1550 Imager 0.68 - 07 Sep 2009
1553 - Imager->new(file => $filename) and other similar incantations will
1554 load the given file.
1555 https://rt.cpan.org/Ticket/Display.html?id=48261
1559 - avoid using CHECK as a label in Imager::Test
1560 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
1562 - re-work most image file test files that require a library into
1563 separate library present/not present files to remove stupidly long
1566 - don't treat rubthrough() outside the bounds of the target image as
1568 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
1570 Imager 0.67_01 - 02 Sep 2009
1575 - correct documentation of default of raw image interleave read
1577 https://rt.cpan.org/Ticket/Display.html?id=42074
1579 - add raw_ prefix to raw read parameters, though the original names
1582 - fail the read if an invalid raw_interleave parameter is supplied
1584 - warn if no interleave or raw_interleave parameter is supplied,
1585 since the documented default was wrong, and incompatible with the
1588 - for reading raw images, if raw_storechannels > raw_datachannels,
1589 set the extra channels in the image to 0
1591 - when probing for executables like freetype-config, search for .bat
1592 and .cmd on MSWin32, as well as .exe.
1593 https://rt.cpan.org/Ticket/Display.html?id=49275
1595 - re-work the external libraries section of README:
1596 - list Debian and Redhat package names for each library
1600 - use the new EU::MM META_MERGE facility instead of generating
1601 META.yml from scratch
1602 https://rt.cpan.org/Ticket/Display.html?id=47888
1604 - use Devel::CheckLib (bundled, modified) to check which release of
1605 libtiff is installed and reject 3.9.0
1606 http://bugzilla.maptools.org/show_bug.cgi?id=2088
1607 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
1609 Imager 0.67 - 12 Dec 2008
1614 - fix a packaging error
1616 Imager 0.66 - 12 Dec 2008
1619 - 24-bit color .ICO/.CUR files can now be read.
1623 - an optimization skipping 0 src alpha values could cause the
1624 rubthrough() to read past the end of a buffer.
1625 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
1627 - corrected a reference leak where writing GIFs would leak memory.
1628 This could also happen calling to_paletted().
1629 Also documented the underlying long existing feature where the
1630 colors parameter is filled with the generated color table and added
1632 http://rt.cpan.org/Ticket/Display.html?id=41028
1634 - write out the image size in bytes field of a BMP correctly.
1635 http://rt.cpan.org/Ticket/Display.html?id=41406
1637 - add limited tests for Imager::ExtUtils
1639 - make Imager::ExtUtils->includes use an absolute path, since
1640 a relative path could cause failures using Inline::C.
1641 http://rt.cpan.org/Ticket/Display.html?id=37353
1643 - re-arrange the POD for Imager::Font::BBox:
1644 - mark total_width(), pos_width(), end_offset() obsolete, since
1645 they're mostly for backwards compatibility
1646 - group width methods and height methods
1647 https://rt.cpan.org/Ticket/Display.html?id=39999
1649 Imager 0.65 - 20 May 2008
1654 - In some cases when an error occurs reading those parts of a JPEG
1655 file after the image the scan-line buffer could be freed a second
1656 time. In cases where the the error occured while reading the image
1657 data it's possible that the buffer could have leaked.
1658 Thanks to Gabriel Vasseur for reporting this and help in tracking
1661 - the gif_screen_height tag was overriding the screen width and being
1662 ignored for the screen height when present.
1663 https://rt.cpan.org/Public/Bug/Display.html?id=35568
1665 Imager 0.64 - 23 April 2008
1668 This is a bug fix release. This includes a fix for a possible
1673 - Possible security issue: The floating point sample path for image
1674 based fills had a buffer overflow. This would overwrite the end of
1675 a malloc()ed buffer with double precision floats.
1676 http://rt.cpan.org/Ticket/Display.html?id=35324
1679 - check that the result of fileno($fh) is defined rather than simply
1680 true when read() or write() is supplied with an fh parameter.
1681 http://rt.cpan.org/Ticket/Display.html?id=35139
1683 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1684 resulting in a SIGSEGV when attempting to scale an image to a size
1685 too large to fit in memory. This is a NULL pointer access issue,
1686 not a buffer overflow.
1687 Added a check for the failure.
1688 scale_calculate() (and hence scale()) will now fail if any of the
1689 scale size parameters are a reference.
1690 http://rt.cpan.org/Ticket/Display.html?id=35172
1692 - Regression: filling a greyscale image with a hatch used the wrong
1693 color channels from the supplied fg/bg colors.
1694 https://rt.cpan.org/Ticket/Display.html?id=35278
1696 - fixed a related problem for image fills.
1698 Imager 0.63 - 7 April 2008
1701 This release primarily contains changes to improve ease of use -
1702 rather than you having to convert images to the appropriate number of
1703 channels, Imager handles it internally. How to handle drawing colors
1704 and the default combine mode is a thornier problem left for some other
1707 - the font libraries are now only initialized when needed.
1708 http://rt.cpan.org/Ticket/Display.html?id=28825
1710 - moved the imtoc.perl code into Imager::Preprocess
1712 - paste() and rubthrough() now adapt the source image data to the
1713 destination, so you can now safely paste/rubthrough from greyscale
1714 images to color images or back, or from alpha channel images to
1715 noalpha channels or back.
1716 https://rt.cpan.org/Ticket/Display.html?id=30908
1718 - rubthrough() now falls back to pasting when the source doesn't have
1719 an alpha channel. This effectively treats the source as having a
1720 max alpha channel, the right thing to do.
1721 http://rt.cpan.org/Ticket/Display.html?id=29944
1723 - re-worked most of the area filling code to use a common set of
1724 functions when filling.
1725 Corrected normal combine mode.
1726 Rewrote most of the combine modes to match the way the SVG draft
1727 defines them with respect to a translucent source and destination.
1728 Added tests for translucent source and destination.
1729 Added tests to check 8-bit/sample and double/sample combines work
1731 https://rt.cpan.org/Ticket/Display.html?id=29879
1733 - writing a 2 or 4 channel image to a JPEG file will now write that
1734 image as if composited against a background, black by default,
1735 overridable with the i_background tag/parameter.
1736 https://rt.cpan.org/Ticket/Display.html?id=29876
1738 - writing a 2 or 4 channel image to a PGM/PPM file will now write
1739 that image as if composited against a background, black by default,
1740 overridable with the i_background tag/parameter.
1741 http://rt.cpan.org/Ticket/Display.html?id=30074
1743 - writing a 2 or 4 channel image to a BMP file will now write that
1744 image as if composited against a background, black by default,
1745 overridable with the i_background tag/parameter.
1746 http://rt.cpan.org/Ticket/Display.html?id=30075
1750 - Imager::Matrix2d->translate() now only requires one of the x or y
1752 http://rt.cpan.org/Ticket/Display.html?id=29937
1754 - mixing qtype scaling now sets all channels of a pixel to zero if
1755 the pixel has zero coverage (zero alpha). This should produce more
1756 compressible output files.
1757 http://rt.cpan.org/Ticket/Display.html?id=32324
1759 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
1761 https://bugzilla.redhat.com/show_bug.cgi?id=166254
1762 I'm not changing the #! lines of the sample code, since it's sample
1763 code, not intended for installation.
1764 http://rt.cpan.org/Ticket/Display.html?id=33408
1766 - some TGA images weren't being detected correctly as TGA images
1767 https://rt.cpan.org/Ticket/Display.html?id=32925
1769 - handling of the left-over bit for 16-bit/pixel TGA images has been
1770 changed to match the behaviour of the GIMP. Previously the bit
1771 being set was treated as an opaque pixel, but one user reported a
1772 problem with loading such an image. I haven't been able to find any
1773 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1774 I'll match it's behaviour. See issue 114913 in the GIMP's
1776 http://rt.cpan.org/Ticket/Display.html?id=32926
1778 Imager 0.62 - 10 December 2007
1781 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
1782 to /path under your home directory.
1783 http://rt.cpan.org/Ticket/Display.html?id=29484
1785 - the old dynaload code used Mach API functions to load dynamic
1786 libraries on Mac OS X. These APIs have been deprecated in OS X
1787 10.5 and were causing some build problems.
1788 So henceforth Imager uses the dlopen() family of functions, and you
1789 will need version 10.3 or later of OS X.
1791 - added the det() function to the transform2() engine.
1792 added the sample quad_to_square.pl
1793 Courtesy Richard Fairhurst.
1794 http://rt.cpan.org/Ticket/Display.html?id=31244
1798 - samples/gifscale.pl sourced the base value for gif_top from
1800 Thanks to Eleneldil G. Arilou for pointing this out.
1802 - t/t82inline.t no longer loads B at runtime, to work around a bug
1803 in some 5.005_0[45] installations.
1804 http://rt.cpan.org/Ticket/Display.html?id=30508
1806 - work around Module::Depends::Intrusive bug #21229
1807 http://rt.cpan.org/Ticket/Display.html?id=30520
1809 - the hardinvert filter no-longer inverts the alpha channel.
1810 http://rt.cpan.org/Ticket/Display.html?id=30002
1812 - the hardinvert filter now supports large samples
1814 Imager 0.61_02 - 28 November 2007
1817 - major TIFF support re-work
1818 http://rt.cpan.org/Ticket/Display.html?id=20329
1820 - added a C level image interface for accessing samples from 1-32
1821 bits, exposed this at the perl level in getsamples()
1823 - the conv filter now works at floating point precision for high bit
1826 - added is_bilevel method to test whether an image should be written as
1827 a bilevel image if the image format supports it.
1829 - added -log-stderr as an Imager import list option
1831 - added some important types to Imager::APIRef
1833 - added test_image_double() to Imager::Test
1837 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
1840 - the scale() method with qtype mixing now handles images with an
1841 alpha channel correctly.
1843 - fixed a broken link from the "animated GIF" entry in the concept index.
1844 Thanks to Slaven Rezic.
1845 http://rt.cpan.org/Ticket/Display.html?id=30889
1847 - on some perl's the infix expression parser test would fail due to
1848 actions in the grammar returning false. Made sure all actions return
1850 Thanks to Richard Fairhurst for spending a lot of time in tracking
1852 http://rt.cpan.org/Public/Bug/Display.html?id=29562
1854 Imager 0.61 - 5 November 2007
1857 - added samples/gifscale.pl, which adjusts the screen size/position tags
1858 when scaling an animated gif
1859 http://rt.cpan.org/Ticket/Display.html?id=27591
1863 - correct handling of sz in matrix_transform() - this should allow
1864 perspective type transformations to work now.
1865 http://rt.cpan.org/Ticket/Display.html?id=29936
1867 - prevent a cast to integer warning on x64 builds in datatypes.c
1868 also fixed some other type warnings
1869 https://rt.cpan.org/Ticket/Display.html?id=30204
1871 - some sub-directory tests depended on files produced by the parent
1873 http://rt.cpan.org/Ticket/Display.html?id=30203
1875 - Imager::Font::Wrap doesn't correctly set savepos
1876 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
1877 http://rt.cpan.org/Ticket/Display.html?id=29771
1879 - test 171 in t/t01introvert.t was failing on perls configured to
1881 http://rt.cpan.org/Ticket/Display.html?id=29413
1883 - the code for the transform2() uminus operator was missing a break.
1884 Added tests for better code coverage of the ops.
1885 http://rt.cpan.org/Ticket/Display.html?id=29296
1887 - the SGI RLE compression code could overflow its compression buffer
1888 http://rt.cpan.org/Ticket/Display.html?id=30334
1890 - the 32-bit output function used by the SGI code only handled values
1891 under 0x10000. This was most noticable when writing large RLE images.
1892 http://rt.cpan.org/Ticket/Display.html?id=30335
1894 - validate chan_count for chans == NULL for each of the i_gsamp()
1896 http://rt.cpan.org/Ticket/Display.html?id=28985
1898 - attempt to work around the test failure at
1899 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
1900 http://rt.cpan.org/Ticket/Display.html?id=29562
1902 - improve the error messages produced when attempting to read or write
1903 an unknown image file format.
1904 http://rt.cpan.org/Ticket/Display.html?id=30103
1906 - improve the transform2() documentation
1907 http://rt.cpan.org/Ticket/Display.html?id=29267
1909 - correctly generate the author key in META.yml
1910 http://rt.cpan.org/Ticket/Display.html?id=30377
1912 - correctly blend a rotated (or matrix_transformed()) image when
1913 performing interpolation in the presence of an alpha channel.
1914 Also corrected the centring of the rotated image on the output
1917 Imager 0.60 - 30 August 2007
1920 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
1921 now has full SGI RGB image format, including RLE and 16-bit/sample
1923 https://rt.cpan.org/Ticket/Display.html?id=8666
1925 - logging functions are now available in the API
1927 - applied Gabriel Vasseur's patch
1928 added documentation, further tests, and support for greyscale images
1929 Obviously problems are my fault :)
1930 https://rt.cpan.org/Ticket/Display.html?id=28142
1932 - the mask for ICO/CUR images is now applied as an alpha channel to
1933 the returned image. For the old behaviour, supply ico_masked => 0
1934 to read() or read_multi(). This should be less confusing when
1935 using Imager as a general image processor.
1936 https://rt.cpan.org/Ticket/Display.html?id=29001
1940 - in some cases it's possible for giflib/libungif to return color
1941 indexes outside the range of colors defined by the image's palette.
1942 We now expand the palette to match the indexes used.
1943 Thanks to Gabriel Vasseur for reporting this.
1945 - fixed various memory leaks that could occur when failing to read png,
1946 jpeg, bmp or tga files.
1948 - to avoid confusion, channels not present in the image are returned as
1949 zero by getscanline(). This has no effect on the C level i_glin()
1950 and i_glinf() API functions which continue to not set the unused
1953 - the convert() method now returns an image of the same sample size as
1955 https://rt.cpan.org/Ticket/Display.html?id=28492
1957 - remove repeated text in Imager::Files
1958 http://rt.cpan.org/Ticket/Display.html?id=27589
1960 - be even more explicit that scale() and friends don't modify the source
1961 image, but return a new image.
1962 http://rt.cpan.org/Ticket/Display.html?id=28570
1964 - improve the error message from errstr() when you try to load a font
1965 for which the driver hasn't been built in Imager.
1966 http://rt.cpan.org/Ticket/Display.html?id=27571
1968 - transparency is now enabled by default when writing GIF images
1969 http://rt.cpan.org/Ticket/Display.html?id=27615
1971 - Imager would not load on Windows 98
1972 http://rt.cpan.org/Ticket/Display.html?id=27653
1974 Imager 0.59 - 14 June 2007
1979 - fixes a regression introduced by the fixes for RT 11972
1980 http://rt.cpan.org/Ticket/Display.html?id=27546
1982 - cropping outside the image would return an Imager object with
1983 no low-level image object, instead of returning false.
1984 Fixed by: Philip Gwyn (Leolo)
1985 http://rt.cpan.org/Ticket/Display.html?id=27509
1987 Imager 0.58 - 16 May 2007
1990 No significant changes from 0.57_01.
1992 Imager 0.57_01 - 11 May 2007
1995 - added to_rgb16 to produce a 16-bit/sample version of an image
1997 - improve freetype 1.x text output efficiency
2001 - search another place for rgb.txt, and check all the places
2002 Imager::Color checks when deciding whether to skip testing it
2003 http://rt.cpan.org/Ticket/Display.html?id=26064
2005 - use a convolution kernel size based on the stddev rather than a
2006 fixed size when performing a gaussian blur
2007 http://rt.cpan.org/Ticket/Display.html?id=25645
2009 - document the difference() method's mindist parameter, and debug it.
2011 - put the Imager release number in the Inline::C generated code to
2012 regenerate Inline code when a new release of Imager is installed.
2013 http://rt.cpan.org/Ticket/Display.html?id=26278
2015 - fix rendering on alpha channel images for the FreeType 1.x driver.
2016 http://rt.cpan.org/Ticket/Display.html?id=11972
2018 - fix rendering on alpha channel images for the T1lib driver.
2019 http://rt.cpan.org/Ticket/Display.html?id=11972
2021 - reworked library probing, we can now set more than one probe
2022 function for a library. Disabled the default (non-freetype-config)
2023 library probe and added an extra probe function that searches for
2024 both ft2build.h and whatever it includes, and adds -I as needed.
2025 Hopefully this will fix build problems like

2027 http://rt.cpan.org/Ticket/Display.html?id=26086
2029 Imager 0.57 - 30 Apr 2007
2032 This is a maintenence release fixing a security issue in Imager.
2034 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
2035 overflow in malloced memory. There will be further discussion of
2036 this issue in the ticket below.
2037 http://rt.cpan.org/Ticket/Display.html?id=26811
2038 CVE-2007-2459 CVE-2007-2413
2039 The descriptions at cve.mitre.org varied in quality, please see the
2040 ticket at rt.cpan.org for a more accurate description of the issue.
2042 Imager 0.56 - 1 Apr 2007
2045 - added support for reading 16-bit/sample PGM/PPM images
2047 - added support for writing 16-bit/sample PGM/PPM images
2049 - improved performance of reading PBM/PGM/PPM images
2051 - added support for writing PBM images if the image is paletted and
2052 contains only black and white
2054 - added a new make_colors value - "mono"
2056 - switched from the svn log Changes to a manual Changes to reduce
2059 - new sample code - samples/flasher.pl
2063 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
2064 was returning an image object with an extra reference, this
2065 resulted in a memory leak.
2066 http://rt.cpan.org/Ticket/Display.html?id=24992
2068 - fix rendering on alpha channel images for the FreeType 2.x driver
2069 http://rt.cpan.org/Ticket/Display.html?id=11972
2071 - reading bmp files now consitently handles short reads. You can now
2072 supply a parameter to treat a short read as successful and set
2074 http://rt.cpan.org/Ticket/Display.html?id=8426
2076 - previously, reading ASCII PBM files required spaces between samples,
2077 even though the format doesn't require that
2079 - improved documentation of the unsharpmask filter (I hope)
2080 http://rt.cpan.org/Ticket/Display.html?id=25531
2082 - force flushing of the output from i_tt_dump_names() and test output
2083 in t/t35ttfont.t to prevent output from being mixed up.
2084 https://rt.cpan.org/Ticket/Display.html?id=24859
2086 - rewrite a conditional expression as an if() to hopefully work around
2087 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
2088 https://rt.cpan.org/Ticket/Display.html?id=25561
2090 - avoid Data::Dumper in regops.perl to support older releases of perl
2091 https://rt.cpan.org/Ticket/Display.html?id=24391
2093 Imager 0.55 - 16 Dec 2006
2096 This is primarily a bug fix release.
2098 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2100 There is one new feature:
2102 - the Win32 font driver now supports UTF8 (RT 22166)
2103 http://www.cpanforum.com/threads/3276
2104 http://rt.cpan.org/Ticket/Display.html?id=22166
2106 Several bugs were fixed:
2108 - the string() method would not output the string "0"
2109 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2111 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2112 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2114 - the gif_disposal and gif_user_input tags weren't being read from
2116 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2118 - gif.c was failing to build under MSVC
2119 http://rt.cpan.org/Ticket/Display.html?id=23922
2121 - in some cases strings passed to the string() method were treated as
2122 terminated by NUL (chr 0)
2123 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2125 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2126 that's the default build name for zlib on Win32.
2127 http://rt.cpan.org/Ticket/Display.html?id=23064
2129 - search $Config{incpath} for headers too, which we should have been
2132 Win32 font driver fixes:
2134 - the global descent value from bounding box was the wrong sign
2135 http://www.cpanforum.com/threads/3276
2137 - if the first or last glyph overflowed the left or right side of the
2138 advance width they would be clipped
2141 Imager 0.54 - 14 Sep 2006
2144 This is primarily a feature release:
2146 - a new qtype value 'mixing' has been added to the scale()
2147 method. This is faster than 'normal', slower than 'preview'. This
2148 is based on the method used by pnmscale, and seems to produce less
2149 blurry results than normal.
2150 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2152 - the rubthrough() method can now render onto images with an alpha
2154 http://rt.cpan.org/Ticket/Display.html?id=20678
2156 - the read_multi() method now falls back to calling doing a single
2157 image read via the read() method and write_multi() will now fall
2158 back to calling write() if a single image is supplied. This means
2159 you can simply call the read_multi() or write_multi() functions
2160 without having to check if the type is formatted by that method.
2161 http://rt.cpan.org/Ticket/Display.html?id=19457
2162 http://rt.cpan.org/Ticket/Display.html?id=19458
2164 - the GIF loop extension can now be written. If you don't have
2165 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2167 http://rt.cpan.org/Ticket/Display.html?id=21185
2169 - getscanline() and setscanline() can now read/write palette index
2170 based data from/to the image for paletted images, by setting type to
2172 http://rt.cpan.org/Ticket/Display.html?id=20338
2174 - we no longer hassle you to disable GIF support
2175 http://rt.cpan.org/Ticket/Display.html?id=20687
2177 - minor documentation fixes
2180 Imager 0.53 - 26 Jul 2006
2183 This is a bugfix release.
2185 Some test code was left in a code path not covered by the test
2186 suite. A test was added to cover this code path and the test code was
2188 http://rt.cpan.org/Public/Bug/Display.html?id=20705
2191 Imager 0.52 - 25 Jul 2006
2194 This is primarily a feature release, but contains a fair few bug
2195 fixes, new features:
2197 - ability to read and write MS Windows ICO and CUR files
2199 - you can now add file format plugins to support new file formats
2201 - add POD coverage tests
2203 - setcolors() and addcolors() now accept color names and so on
2204 instead of requiring Imager::Color objects.
2205 http://rt.cpan.org/Ticket/Display.html?id=20056
2207 - flood_fill() can now fill to a specified border color instead of
2208 just to the area the same color as the seed.
2209 http://rt.cpan.org/Ticket/Display.html?id=19618
2214 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2215 calculating the advance width.
2216 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2218 - bounding_box for the T1 driver wasn't including leading and
2219 trailing spaces in the bounding box as the other drivers did, it also
2220 produced strange results for empty strings or strings containing only
2223 - when reading CMYK jpeg images they were being transferred to the
2224 image object as is, producing a four channel image. It only looked ok
2225 due to an old still unfixed Photoshop bug. We now convert from the
2226 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2227 http://rt.cpan.org/Ticket/Display.html?id=20416
2229 - reading a CYMK TIFF would result in a 4 channel image, reading any
2230 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2232 http://rt.cpan.org/Ticket/Display.html?id=20415
2234 - added /usr/local/include to the default include search path, since
2235 we were already searching /usr/local/lib for libraries.
2237 And various minor fixes and documentation updates.
2240 Imager 0.51 - 23 Apr 2006
2243 - fix a validation bug when processing JPEG EXIF data that can cause
2245 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2247 - fix mis-processing of the src_maxx and src_maxy parameters of the
2249 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2251 - fix a problem in Imager's "smart" handling of the color parameter
2253 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2256 Imager 0.50 - 29 Mar 2006
2259 - CRITICAL: fixes a segmentation fault from attempting to write a 2
2260 or 4 channel image to jpeg or a 2 channel image to tga where the
2261 output is an in-memeory buffer.
2262 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2264 - fixes an incorrect pointer parameter in the PNG code
2265 http://rt.cpan.org/Public/Bug/Display.html?id=18051
2267 - skip Inline::C tests when building in a directory with spaces
2268 http://rt.cpan.org/Public/Bug/Display.html?id=18049
