1 Imager release history. Older releases can be found in Changes.old
3 Imager 1.005 - 16 Apr 2016
6 It's now been ten years since I switched to the new Changes file in
9 - revert the ivdformat probes, they don't work as is and trying to
10 fix them is too much work for now.
12 Imager 1.004_004 - 15 Apr 2016
15 - test that the ivdformat from Config is correct and look for a valid
17 For the strange Win32 failures.
19 - fix a copy and paste error in pod in samples/samp-form.cgi
21 Imager 1.004_003 - 23 Mar 2016
24 - add some extra error reporting to the I/O layers tests, this might
25 help catch a failure seen on Win32.
26 http://cpantesters.org/cpan/report/99781689-6bf5-1014-897a-75cb4eee1325
28 Imager 1.004_002 - 20 Mar 2016
31 - don't use the seek() method on opened() handles in
32 t/200-file/400-basic.t. In older versions of perl such handles are
33 only IO::Handle objects, not IO::File, and don't have a seek()
36 Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
39 - re-work the t/200-file/400-basic.t to correctly handle failures
40 It's custom ok() function didn't have a prototype and didn't use scalar().
41 This caused ok() to use the note instead of the value being tested when
42 the method called returned an empty list. For an example of the problem
43 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
45 - remove some noise from when Imager tried to work with bugs in old
46 versions of giflib. I can't do much about the new bugs.
48 - the new autolevels filter (Imager 0.99) used an integer for the
49 sample scaling factor which caused the top output level to be too
50 low (depending on the scaling required.) It now uses a double.
51 https://rt.cpan.org/Ticket/Display.html?id=111871
53 - the new autolevels filter had off-by-one errors calculating the
54 minimum and maximum luminance from the histogram. This slightly
55 reduced the contrast of the output image.
56 https://rt.cpan.org/Ticket/Display.html?id=111871
58 - the new autolevels filter now uses a lookup table for 8-bit images
59 to avoid a floating point multiply for each sample.
60 https://rt.cpan.org/Ticket/Display.html?id=111871
62 - fixed several memory leaks detected by valgrind:
64 - addcolors() leaked the temporary array of colors supplied to the
67 - make_palette() leaked the temporary image array (not the images
68 themselves) passed to the internal API.
70 - combine()/i_combine() leaked its working row buffers
72 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
73 buffer if there were too many colors
75 - getcolorcount()/i_count_colors() leaked the sample buffer if
76 there were too many colors.
78 - the nearest_color filter (undocumented until I find a use for it)
79 leaked both temporaries passed to the API and internal buffers
81 - the internal process of upgrading a paletted image to a direct
82 color image would leak a context object reference count.
84 - a write failure when writing to a GIF file could leak memory.
86 - failing to write to a 1-bit/pixel ICO image could leak memory.
88 - Imager no longer deliberately leaks the context object from the
89 initial thread. This was done to ensure there was always a context
90 object available, but the code that needed that now handles the
93 - fixed some uninitialized memory usage detected by valgrind:
95 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
96 i_matrix_transform_bg() didn't initialize a working color value
97 if there was zero pixel coverage.
99 - i_ft2_cp() didn't initialize the complete color when producing an
100 intermediate image. This caused uninitialized value usage when
103 Imager 1.004 - 8 Nov 2015
106 - Imager::Color::Table is now pre-loaded by the preload() method.
107 https://rt.cpan.org/Ticket/Display.html?id=104896
109 - fix an assertion triggered under perl 5.23.4.
110 Thanks to A. Sinan Unur for the report and the patch.
112 - Imager->new can now be used to read raw image files.
113 https://rt.cpan.org/Ticket/Display.html?id=106836
114 Thanks to Richard Kelsch for reporting this.
116 - deal with output changes from Pod::Spell
117 https://github.com/perl-pod/Pod-Spell/issues/21
119 Imager 1.003 - 12 May 2015
122 - update 1.002 release notes to include the center change for filled
125 - flood_fill() would escape beyond a 4-connected space under some
127 Added many more flood_fill() tests.
128 https://rt.cpan.org/Ticket/Display.html?id=103786
130 Imager 1.002 - 3 Apr 2015
133 - drawing anti-aliased filled circles is now 10 to 50 times faster
134 depending on the size of the circle.
135 This also changed the center from being the center of the pixel to
136 being the top left of the pixel to match the filled arcs drawn by
138 https://rt.cpan.org/Ticket/Display.html?id=101682
140 - enhancements to polygon filling:
142 - added a mode parameter to control how overlapping regions behave
144 - added a polypolygon() method to fill more than one polygon at a
147 - polygon filling is now exposed through the API.
149 - added colormodel(), alphachannel() and colorchannels() methods.
150 These were added for two reasons:
152 - a future version of Imager may allow the number of channels in
153 an image to not directly represent the color model of an image.
154 eg. a greyscale TIFF image with multiple alpha channels.
156 - a future version of Imager may allow an image to be read without
157 translation, for example a TIFF file that contains measurements
158 from an instrument. Currently Imager transforms the samples into
159 the range 0.0 ... 1.0 which may means the user has to translates
162 An untranslated image would be unusable as image data, so
163 colormodel() would return "unknown" in this case.
165 Similarly a CMYK image might be returned as an "unknown" color
166 model image, if the caller chooses to disable translation to
169 Imager 1.001 - 2 Jan 2015
172 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
173 Thanks to Slaven Rezic for the report and the patch.
174 https://rt.cpan.org/Public/Bug/Display.html?id=98234
176 - GIF: clean-up a test file if the test for the giflib 4.2.0 file
179 - fix Imager::Matrix2d::rotate()'s centre point handling
180 https://rt.cpan.org/Public/Bug/Display.html?id=99959
182 - ICO: don't apply the icon mask to images with an alpha channel by
184 https://rt.cpan.org/Public/Bug/Display.html?id=99507
186 - make verbose probing output more verbose
188 - use Imager::Probe to probe for freetype 1.x
189 https://rt.cpan.org/Ticket/Display.html?id=100502
191 - The --enable and --disable parameters to the top-level Makefile.PL
194 - update the bundled/modified Devel::CheckLib to handle the gcc-4
197 Imager 1.000 - 28 Jul 2014
200 There's nothing special about Imager 1.000, it's just another release.
202 - fix the skip check for the iolayer qr// buffer test
204 - improve error reporting for the iolayer test failing on a small
205 number of Win32 CPAN testers
207 Imager 0.99_02 - 21 Jul 2014
210 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
211 the blue channel in the generated palette, and allow each color
212 component to be in the range 100..255 instead of just 100..254.
213 Thanks to Ralf Neubauer.
214 https://rt.cpan.org/Ticket/Display.html?id=97086
216 - revert "improved the XS for i_io_read() and i_io_raw_read()"
217 This caused problems with older perls and didn't provide much of a
218 performance improvement.
220 - support Inline 0.57 and later.
221 Inline 0.57 changed the "with" interface.
222 https://rt.cpan.org/Ticket/Display.html?id=97108
224 - don't define our own MAXINT macro, it conflicts with windows header
225 files and in a few places it was the wrong value to use anyway.
226 https://rt.cpan.org/Ticket/Display.html?id=96425
228 Imager 0.99_01 - 29 Jun 2014
231 - GIF: add support for giflib 5.1.0, which added error code pointer
232 parameters to EGifCloseFile() and DGifCloseFile().
233 https://rt.cpan.org/Ticket/Display.html?id=96756
235 - GIF: avoid a double-free when do_write() fails.
237 - fix SV type probing to work on perl before 5.12. Broken in 0.99.
238 https://rt.cpan.org/Ticket/Display.html?id=96761
240 - PNG: skip the benign error test before libpng 1.6.0, since the
241 error we're testing didn't exist before 1.6.0.
242 https://rt.cpan.org/Ticket/Display.html?id=94717 (continued)
244 Imager 0.99 - 25 Jun 2014
247 - Imager::IO->new_buffer() (and hence Imager->read()'s data
248 parameter) now accepts a reference to a scalar as well as just a
250 https://rt.cpan.org/Ticket/Display.html?id=92785
252 - Imager::IO->new_buffer() now always makes a copy of the passed in
253 buffer to avoid problems with temporary objects used for the return
255 https://rt.cpan.org/Ticket/Display.html?id=92785
257 - improved the XS for i_io_read() and i_io_raw_read()
258 https://rt.cpan.org/Ticket/Display.html?id=92738
260 - load plugins from absolute paths on Android
261 Thanks to Brian Fraser.
262 https://rt.cpan.org/Ticket/Display.html?id=93272
264 - added the jpeg_optimize parameter for writing JPEG files. This can
265 significantly reduce file sizes, but uses more memory and time.
266 https://rt.cpan.org/Ticket/Display.html?id=94292
268 - the autolevels filter now works on the luminosity of the image
269 rather then working per channel. The old autolevels filter is
270 still available as "autolevels_skew".
271 https://rt.cpan.org/Ticket/Display.html?id=94413
273 - Imager::File::PNG now supports libpng 1.6.10.
274 1.6.10 changed CRC errors from benign errors to normal errors,
275 which broke the test which used CRC errors to check for benign
276 error support. Switched to using a 1-bit grey-scale image with a
277 palette to test for benign errors.
278 https://rt.cpan.org/Ticket/Display.html?id=94717
280 Imager 0.98 - 3 Jan 2014
283 Incompatible changes:
285 - the return value of setpixel() has changed.
287 Previously the return values for undrawable pixels vs caller errors
288 changed depending on whether you used the multiple pixel calling
289 mechanism, or the single pixel mechanism.
293 - for an invalid parameter, such as an unknown colour, or missing
294 parameter, an empty list (or undef in scalar context) is
295 returned, and errstr() is set,
297 - otherwise the number of pixels drawn is returned. If none of
298 the pixels could be drawn (they were all outside the image), "0
299 but true" is returned.
301 https://rt.cpan.org/Ticket/Display.html?id=87650
305 - when drawing on an image with an alpha channel where the source
306 minimum is greater than zero, Imager would read from beyond the end
307 of a malloc() allocated buffer. In rare circumstances this could
308 lead to some of the source image not being written to the target
309 image, or possibly to a segmentation fault.
310 I don't believe this has any security concerns beyond that.
312 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
313 text drawn would be nonsense. This would also read beyond the end
314 of a malloced buffer.
316 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
318 https://rt.cpan.org/Ticket/Display.html?id=88993
320 - Imager::Font::Wrap no longer requires the image parameter.
321 https://rt.cpan.org/Ticket/Display.html?id=87338
323 - a documentation typo fix in Imager::Transformations
324 Thanks to Adrian Yee.
325 https://rt.cpan.org/Ticket/Display.html?id=88598
327 - Image::Probe, Imager's internal module for probing library
328 locations now searches the directories specified by LD_RUN_PATH,
329 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
330 and the corresponing s/\blib$/include/ directories for header
332 https://rt.cpan.org/Ticket/Display.html?id=86428
334 Imager 0.97 - 15 Jul 2013
337 No changes from 0.96_02.
339 Imager 0.96_02 - 8 Jul 2013
342 - PNG: treat a version mismatch between headers and library as a
344 https://rt.cpan.org/Ticket/Display.html?id=86659
346 - PNG: the check for benign error support is more complex than a
347 simple library version check, check for the appropriate macro.
348 Thanks for Slaven Rezic for following up on my CPAN Testers result
350 https://rt.cpan.org/Ticket/Display.html?id=86659
352 - W32: add a missing head1 AUTHORS to the old Win32.pm
353 https://rt.cpan.org/Ticket/Display.html?id=86658
355 Imager 0.96_01 - 1 Jul 2013
358 - TIFF: handle SampleFormat = 2 by translating the signed integer
359 values to unsigned by flipping their sign bits.
361 Handle SampleFormat = 3 where possible.
363 SampleFormat is ignored for paletted images.
365 Mixed SampleFormat are handled incorrectly, since libtiff returns
366 only the first SampleFormat value, and an image with both an alpha
367 channel and SampleFormat = 2 for color channels probably has a
368 different SampleFormat for the alpha channel.
370 https://rt.cpan.org/Ticket/Display.html?id=74540
373 https://rt.cpan.org/Ticket/Display.html?id=69243
375 - Imager::Color's rgba() method now returns its values as integers
376 instead of floating point. (IV instead of NV).
378 - The XS for i_map() and i_matrix_transform() now use the AV *
379 typemap instead of rolling their own.
381 - The XS for DSO_call() now uses the HV * typemap instead of
384 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
385 i_gradgen() now use a new T_AVARRAY typemap that greatly
386 simplifies the XS code.
388 - many other minor XS changes
390 - some XS code formatting
392 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
393 now renders in alpha-combining mode, to match antialiased output.
394 https://rt.cpan.org/Ticket/Display.html?id=73359
396 - add sample code and cookbook notes for drawing a blurred drop-shadow.
398 - add support for libpng 1.6, which changed the defaults for
399 reporting some types of error.
400 https://rt.cpan.org/Ticket/Display.html?id=85746
402 - FT2: use gsamp/psamp() to transfer pixels from the work image to
403 the output image instead of gpix/ppix.
404 https://rt.cpan.org/Ticket/Display.html?id=83478
406 - eliminate various GCC warnings, mostly initialized but otherwise
409 Imager 0.96 - 19 May 2013
412 - rearrange Imager's test files.
413 https://rt.cpan.org/Ticket/Display.html?id=84596
415 - Imager::Probe::_gcc_lib_paths now forces C locale.
416 A sufficiently recent gcc prints localized keys for the search
417 paths, which avoids that localization.
418 https://rt.cpan.org/Ticket/Display.html?id=84963
420 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
421 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
423 https://rt.cpan.org/Ticket/Display.html?id=85262
424 reported by Andreas König
426 - add a test for unclosed POD in C source, and fix the errors it
428 https://rt.cpan.org/Ticket/Display.html?id=74875
430 - fix some spelling errors detected by the newer aspell in Debian
433 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
434 thanks to gregor herrmann <gregoa@debian.org>
435 https://rt.cpan.org/Ticket/Display.html?id=85413
437 - add a test for standard =head1 commands and fix the errors found
439 Imager 0.95 - 19 Apr 2013
442 - handle the SVf_UTF8 flag correctly on magic strings passed to
443 Imager::IO's write() and raw_write() methods.
444 This may misbehave in perl 5.6.x since the UTF8 flag may not be
445 visible in the main SV after SvGETMAGIC().
446 https://rt.cpan.org/Ticket/Display.html?id=83438
448 - document that bounding_box() ignores the transformation matrix
449 supplied to tranform() for fonts.
450 https://rt.cpan.org/Ticket/Display.html?id=84106
452 Imager 0.94_02 - 5 Apr 2013
455 - enable debug logging for the standard font tests
457 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
458 due to a bug in that version of perl.
460 - don't test for read() failing on a write-only handle in 5.8.x and
461 earlier, this was fixed in change 862083f7e4 in perl.
463 - report the version of Inline found during testing (an attempt to
464 diagnose some intermittent failures.)
466 Imager 0.94_01 - 2 Mar 2013
469 - NOTE: possibly backward incompatible:
470 support reading from/writing to perl filehandes that aren't raw
473 This allows Imager's I/O to honour handles with layers such as
474 gzip, scalar file handles or tied file handles.
476 This is backward incompatible in that previous Imager would simply
477 use fileno() to retrieve the fd for the file and call write(2) etc
479 https://rt.cpan.org/Ticket/Display.html?id=78843
481 - moved most of README to lib/Imager/Install.pod which should make it
482 more accessible to the "web" generation, also significantly updated
485 - updated README's for the separately distributed modules to refer to
486 Imager::Install, and that they need -dev versions of packages
487 https://rt.cpan.org/Ticket/Display.html?id=81265
489 - the JPEG test code now reports the compile-time library version
491 - avoid a possible compiler optimization issue on CentOS 5.9 i386 by
492 rearranging (and mildly optimizing) some code.
493 https://rt.cpan.org/Ticket/Display.html?id=83212
495 - fix a POD error in Imager::Fill (detected on new Pod-Simple)
496 https://rt.cpan.org/Ticket/Display.html?id=83434
498 - fix a broken link to Graphics::Magick
499 https://rt.cpan.org/Ticket/Display.html?id=82743
501 - drawing text to a channel with FT2 would draw with random coverage
502 due to an uninitialized alpha channel.
504 - marked the function pointer underlying the mm_log() API with the
505 correct gcc magic and fixed the resulting warnings.
507 - fixed some other compiler warnings
509 - Imager::Font::W32 now properly reports text drawing errors
510 https://rt.cpan.org/Ticket/Display.html?id=70098
512 - handle the SVf_UTF8 flag correctly on magic (eg. overloaded)
513 strings passed as text to draw(), bounding_box(), has_chars(),
514 glyph_names() (where supported) in each of the font drivers.
515 This may misbehave in perl 5.6.x since the UTF8 flag may not be
516 visible in the main SV after SvGETMAGIC().
517 https://rt.cpan.org/Ticket/Display.html?id=83438 (partial)
519 Imager 0.94 - 15 Dec 2012
520 =========================
522 Variations on some of these changes were included in development
525 - improved thread safety
526 - the internal error stack and log file handle are now in a per-thread
528 - JPEG now captures IPTC information in a thread-safe way
529 - avoid globals where possible for warning capture in libtiff
530 - use a mutex to avoid re-entering thread-unsafe giflib
531 - use a mutex to avoid re-entering thread-unsafe tifflib
532 - use a mutex to avoid re-entering thread-unsafe T1Lib
533 - use a library handle per thread for freetype 2.
534 - use an engine handle per thread for freetype 1.x.
535 - originally these changes broke ABI compatibility, this has been
538 - clarify the return value of getpixel();
539 https://rt.cpan.org/Ticket/Display.html?id=81198
541 - fixed a race condition in parallel testing for T1
543 - fixed a bug in handling yoff for untransformed image-based fills
545 - documentation improvements for Imager::Fill
547 - FT2: report the library version while testing.
549 Imager 0.93 - 15 Oct 2012
554 - previously a transparency enabled GIF write (the default) would
555 always use a GIF89a header even if none of the images were
558 - previously the probe step for freetype-config would fail on cygwin
560 - catch an invalid matrix parameter to convert() instead of crashing
561 https://rt.cpan.org/Ticket/Display.html?id=79922
563 - remove the 16-bit/sample limitation from the documentation for
564 setsamples(), it hasn't applied for many releases.
565 https://rt.cpan.org/Ticket/Display.html?id=79989
567 - don't copy setsamples() data parameter, it may be a large scalar
568 https://rt.cpan.org/Ticket/Display.html?id=79990
570 - clean up .dSYM directories generated performing probes on OS X
573 - pass the --verbose command-line option through to Imager::Probe in
574 sub-module's Makefile.PLs
575 https://rt.cpan.org/Ticket/Display.html?id=75878
579 - support for giflib 5.0. (5.0.1 and later)
580 https://rt.cpan.org/Ticket/Display.html?id=79029
581 The giflib API Imager uses doesn't have a mechanism to set the
582 header version in 5.0.0.
584 - update the GIF library probe code to check for the new giflib 5.0.1
585 EGifSetGifVersion() function, and to check for the giflib 4.2.0
586 uninitialized gif89 bug.
587 https://rt.cpan.org/Ticket/Display.html?id=79679
588 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
590 - avoid static variables when capturing IPTC data from JPEG files
592 - match Imager::Font;:T1's error message translations to those from
593 later versions of T1Lib.
595 - for libtiff versions that support extended warning handlers (3.8.0
596 or later), use them to avoid some global variables.
598 - note Image::ExifTool for better metadata support.
599 https://rt.cpan.org/Ticket/Display.html?id=79251
601 Imager 0.92 - 14 Aug 2012
604 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
605 correctly for both probing and runtime.
606 https://rt.cpan.org/Ticket/Display.html?id=77672
608 - allow building JPEG/imexif.c on C89 compilers.
610 - allow building GIF/imgif.c on C89 compilers.
612 Imager 0.91 - 4 Jun 2012
617 - The size of rotated images is no longer rounded up so aggressively.
618 Added rounding to the linear interpolation done for rotate() and
619 matrix_transform() for 1 and 3 channel 8-bit images.
620 Adjusted the two tranlate matrices used to build the final rotation
621 matrix to use the distance between the outlier pixels rather than
622 the pixel dimensions (ie. dimension-1).
623 With all of this the output of rotate(degrees => 270) on an 8-bit
624 image exactly matches the output of rotate(right => 270).
625 https://rt.cpan.org/Ticket/Display.html?id=77063
629 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
630 internals, those names only matter for the XS interface.
632 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
633 the API level compiled into a loadable module such as
634 Imager::File::GIF doesn't match that of Imager. Previously it
635 could be difficult to determine exactly which module was failing to
637 https://rt.cpan.org/Ticket/Display.html?id=77173
639 - added Imager->check_file_limits() as an interface to the
640 i_int_check_image_file_limits() API.
642 - Imager->set_file_limits(reset => 1) now resets the limits to the
643 defaults rather than setting them all to unlimited.
645 - wrote a brief security note as Imager::Security
646 https://rt.cpan.org/Ticket/Display.html?id=68910
648 Imager 0.90 - 30 Apr 2012
653 - Imager::Test::is_imaged() attempted to process an "epsilon"
654 parameter but the prototype didn't allow for the extra parameter.
655 Corrected the prototype.
657 - when downconverting samples (eg. from floating point to 8 bit)
658 Imager now rounds the sample value rather than attempting to
659 allocate input values over output values equally. The old
660 behaviour had the probably surprising effect of converting a
661 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
663 This may result in slightly different 8 or 16-bit output images.
665 - BI_BITFIELD BMP images were handled incorrectly, both in
666 incorrectly calculating the space required for the masks and in
667 processing the image data itself.
668 https://rt.cpan.org/Ticket/Display.html?id=76736
670 - some odd width BMP BI_RLE4 images use run lengths that run one off
671 the edge of the image. Imager now allows this, discarding the
674 - odd length RLE4 runs in BMP images were decoded incorrectly.
676 - pkg-config could sometimes return a library that was in a directory
677 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
678 If no -L is included in the pkg-config library information check if
679 EU::MM can find the library, and if not, search our configured
680 directories and insert that into the library flags.
681 https://rt.cpan.org/Ticket/Display.html?id=75869
683 - Imager::Probe can now probe for libraries with dependent libraries,
684 common for static linking, eg. libpng requires libz.
685 https://rt.cpan.org/Ticket/Display.html?id=74043
687 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
689 - added alternative probe configurations that try to link libz, to
690 handle a statically linked libpng.
691 https://rt.cpan.org/Ticket/Display.html?id=74043
693 - if a probe includes testcode, Imager::Probe now checks that code as
694 part of the process of checking each configuration rather than as a
695 post test of the found configuration. This allows alternate
696 configurations to be checked if a matching but non-working
697 configuration is found.
698 https://rt.cpan.org/Ticket/Display.html?id=74043
702 - when reading or writing images via callbacks, the default callbacks
703 now push an error message indicating that a required callback was
704 called but not supplied.
705 https://rt.cpan.org/Ticket/Display.html?id=76782
707 - clarify which callbacks are required for reading and writing TIFF
710 - improve logging for creation of callback I/O layers.
712 - a little more documentation for Imager::Probe.
714 - the i_get_file_background() and i_get_file_backgroundf() APIs now
715 return int to indicate whether the i_background tag was found.
718 - improve error reporting
719 - add png_interlace, png_bits tags
720 - read paletted images as paletted images, including transparency
721 - read 1 bit greyscale images as a type suitable for other file
722 handlers to write as bilevel
723 - read 16 bit/sample PNG as 16-bit/sample Imager images
724 - write "bilevel" paletted images as 1 bit grayscale images
725 - write paletted images as paletted images
726 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
728 - improved metadata support
729 https://rt.cpan.org/Ticket/Display.html?id=29268
731 Imager 0.89 - 18 Mar 2012
736 - getpixel(..., type => "float") and the API i_gpixf() have been
737 broken on paletted images since they were implemented.
738 https://rt.cpan.org/Ticket/Display.html?id=75258
742 - links in the METHOD INDEX now point at the method documentation
743 rather than the heading you can find them under.
744 https://rt.cpan.org/Ticket/Display.html?id=71495
746 - Imager (and the bundled dynamic modules) no longer fallback to
747 using DynaLoader if loading via XSLoader fails.
748 For the bundled modules this could hide useful error messages.
749 https://rt.cpan.org/Ticket/Display.html?id=75560
751 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
752 buffer in the array of allocations, but just stores the filename
753 pointer and line number.
754 https://rt.cpan.org/Ticket/Display.html?id=70388
756 Imager 0.88 - 22 Feb 2012
759 - describe how to build libgif etc on OS X in such a way as to be
760 compatible with a fat binary perl (such as the system perl), in
762 https://rt.cpan.org/Ticket/Display.html?id=73371
764 - update the change notes for 0.77_01 to indicate that libungif
767 - add some other imaging modules to SEE ALSO
768 https://rt.cpan.org/Ticket/Display.html?id=73906
770 - note that the generator of the apparently non-DFSG-free postscript
771 in MMOne.pfb is a Debian package.
773 - setsamples() is now a true complement to getsamples() - it can
774 write 8-bit or floating point samples from a scalar or array
775 reference. This adds i_psamp() and i_psampf() to the C level API.
777 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
778 changed to make better use of the typemap, but these aren't part of
779 the perl level API anyway. There were no changes to the C level
780 interfaces to these functions.
782 - getpixel() and setpixel() now accept a mix of scalar and array
783 references for the x and y parameters, and unequal array lengths is
785 https://rt.cpan.org/Ticket/Display.html?id=73697
789 - correctly calculate the size of a rotated image
790 https://rt.cpan.org/Ticket/Display.html?id=69261
792 - fix incorrect rounding of color values for matrix_transform() and
794 https://rt.cpan.org/Ticket/Display.html?id=69261
796 - Win32 text output is now done in normal combine mode, the alpha
797 component of the color is now significant.
798 https://rt.cpan.org/Ticket/Display.html?id=70014
800 - remove long unused gif case from read()
801 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
803 - the getsamples() target parameter was being treated as a hashref
804 when it's meant to be an array reference.
805 https://rt.cpan.org/Ticket/Display.html?id=74882
807 - getpixel() and setpixel() now returns an empty list when invalid
808 parameters are supplied.
809 Invalid values for type now result in an error for getpixel().
810 https://rt.cpan.org/Ticket/Display.html?id=73697
812 Imager 0.87 - 03 Jan 2012
815 - document the return value of the filter() method.
816 https://rt.cpan.org/Ticket/Display.html?id=72369
818 - document i_gsamp_bits() and i_psamp_bits().
819 https://rt.cpan.org/Ticket/Display.html?id=68815
821 - properly increment the Imager::Matrix2d $VERSION.
823 - actually include the Imager::Test tests in the dist
825 - correctly read and write 256x256 pixel ICO files
826 https://rt.cpan.org/Ticket/Display.html?id=69599
828 - make the error message from read() or read_multi() when they can't
829 identify the file type match reality.
830 https://rt.cpan.org/Ticket/Display.html?id=72475
832 - read() now uses $FORMATGUESS if it can't determine the file type
833 based on the file header, to match read_multi().
835 - re-work and add tests for def_guess_type(). def_guess_type() no
836 longer returns any random file extension as the file type.
838 - add gray4, gray16 and gray as presets for make_colors.
839 https://rt.cpan.org/Ticket/Display.html?id=67911
841 - add make_palette() method that produces a palette from one or more
844 - fix the Imager dependency for the separately distributed font
846 https://rt.cpan.org/Ticket/Display.html?id=72643
848 - fix i_render_color() to properly draw in "normal" mode - ie. when
849 writing to a 1 or 3 channel image the second or fourth channel of
850 the source color was being ignored, it is now significant.
851 https://rt.cpan.org/Ticket/Display.html?id=71564
853 Imager 0.86 - 31 Oct 2011
856 - improve error reporting for W32 tests
858 Imager 0.85_02 - 24 Oct 2011
863 - eliminate unused i_gif_opts type (clean-up)
864 https://rt.cpan.org/Ticket/Display.html?id=69245
866 - fix combine=0 fill color anti-aliasing on the double/sample path
867 https://rt.cpan.org/Ticket/Display.html?id=71309
869 - make default text color non-transparent
870 https://rt.cpan.org/Ticket/Display.html?id=71469
872 - apply the last of the Debian unforwarded spelling fixes
873 https://rt.cpan.org/Ticket/Display.html?id=70656
875 - the log() method used its message parameter as a C level format
877 https://rt.cpan.org/Ticket/Display.html?id=71653
879 - provide our own STRLEN typemap entry for older perls.
880 https://rt.cpan.org/Ticket/Display.html?id=71641
882 - add extra ppport.h configuration to support older perls.
884 - depend on Scalar::Util, since we use it and older perls don't have
887 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
888 to synthesize it from overloaded "".
890 - use T1_StrError() for error messages on modern libt1
891 https://rt.cpan.org/Ticket/Display.html?id=69879
893 - actually load the font rather than just adding it to the catalog on
896 - Imager::Font->new now produces better error messages for the T1
899 - the font has_chars() method now returns perl's true and false
900 values in list context rather than integers, which should be more
902 https://rt.cpan.org/Ticket/Display.html?id=69158
904 - the btm data structure used by the flood_fill code is now
905 initialized more efficiently.
906 https://rt.cpan.org/Ticket/Display.html?id=68994
908 - updated the Thanks list in README
909 https://rt.cpan.org/Ticket/Display.html?id=71607
911 - check there's at least one coefficient for the convolution filter
912 https://rt.cpan.org/Ticket/Display.html?id=68993
914 - make the APIRef synopsis ordering consistent, older versions of
915 perl could order it differently.
916 https://rt.cpan.org/Ticket/Display.html?id=71675
918 - we rely on Config.pm's d_vsnprintf as to whether we use
919 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
920 though it only has _ prefixed versions of these. Define our own
921 prefixed names on Win32.
922 https://rt.cpan.org/Ticket/Display.html?id=71642
924 - fix library detection with MSVC
926 - search a few more library directories, so EU::MM doesn't discard
927 them. Hopefully fixes:
928 https://rt.cpan.org/Ticket/Display.html?id=71643
930 Imager 0.85_01 - 10 Oct 2011
933 - add simple tests for the Imager::Test test_image generators
935 - io_glue I/O buffering re-work:
937 - reorganize io_glue to do it's own buffering by default
939 - the unbuffered functions are available as i_io_raw_read() (or
940 raw_read() from perl) etc but are not recommended for typical
943 - use the new i_io_peekn() when checking for file magic to avoid
944 seek, allowing Imager to detect the file type and read the file
945 from an unseekable stream (for formats that don't use random
948 - added several new I/O layer API functions.
950 - fix the TGA performance problem, most noticably on Win32
951 https://rt.cpan.org/Ticket/Display.html?id=70037
953 - TIFF now uses wrapper functions of the correct types to avoid casts
954 https://rt.cpan.org/Ticket/Display.html?id=69912
956 - the callback IO object did its own buffering, controlled by the
957 maxbuffer parameter supplied to the read() and write() methods.
958 This buffering has been removed, to avoid redundancy with the
959 common io_glue buffering. This also avoids a bug in that code
960 which could rarely pass a zero length to the read callback and
961 then panic about the result.
963 - the callback IO object now tests the result of calling the close
964 callback, which should return true for success.
966 - the PNM reader did its own buffering. This buffering has been
967 removed to avoid redundancy with the common io_glue buffering.
969 - previously the read handlers for fd and callback I/O layers would
970 call the underlying interface (POSIX read or your supplied callback)
971 until it filled the buffer. It now only makes one call.
973 - added public constructors for I/O layer objects (see Imager::IO)
975 - all core file handlers now use the i_io_foo() wrappers to gain
976 access to buffered I/O rather than calling the I/O layer
979 - all core file handlers now check for error on close.
981 - Backward compatibility: if you hava custom file handlers, you can
982 use i_io_write() etc since they're available as macros in older
985 - eliminate the final remnants of io_glue_commit_types().
987 - bump IMAGER_API_VERSION, since the above may break assumptions.
989 - removed the long unused i_gen_reader() and i_gen_writer() utility
992 Imager 0.85 - 29 Aug 2011
995 The main changes in the release versus 0.84 are:
997 - on 64-bit systems, 64-bit types are consistently used for image
998 dimensions and co-ordinated, and for memory block sizes.
1000 - handle IFD loops in TIFF files correctly. Previously this would
1001 lead to an infinite loop.
1005 - fix the link in the getheight() entry in the method index
1007 Imager 0.84_02 - 22 Aug 2011
1010 Development release, this will become 0.85 if CPAN testers is
1015 - the image file limits set by set_file_limits() weren't being
1016 checked when reading TIFF files.
1017 https://rt.cpan.org/Ticket/Display.html?id=69915
1019 - Provide more information about file format module load errors on a
1020 failed image file read() or write().
1021 https://rt.cpan.org/Ticket/Display.html?id=69194
1023 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
1024 through TIFF images, since it checks for IFD loops.
1025 https://rt.cpan.org/Ticket/Display.html?id=69914
1027 - don't leak memory when out of range palette indexes are supplied to
1029 https://rt.cpan.org/Ticket/Display.html?id=69242
1031 - require a later version of CPAN::Meta to ensure JSON::PP and
1032 CPAN::Meta::YAML are available.
1033 https://rt.cpan.org/Ticket/Display.html?id=69008
1035 - hoist the per-line calculations for the flines implementations, and
1036 modernize the tests a bit.
1037 https://rt.cpan.org/Ticket/Display.html?id=70126
1039 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
1040 them when available.
1041 https://rt.cpan.org/Ticket/Display.html?id=69147
1043 - if t1lib failed to reinitialize it would be left as marked
1045 https://rt.cpan.org/Ticket/Display.html?id=69877
1047 - update the bundled (and still modified) Devel::CheckLib
1048 https://rt.cpan.org/Ticket/Display.html?id=69170
1050 Imager 0.84_01 - 8 Aug 2011
1053 Development release as a sanity check for the types re-work.
1055 Massive types re-work:
1057 - the type used internally for pixel co-ordinates and image sizes is
1058 now 64-bit on 64-bit platforms (at least sane ones).
1060 - size_t is now used consistently for memory block sizes.
1062 - since this changes the binary interface, the Imager API version has
1063 been incremented. Any module that uses the API will need to be
1064 rebuilt. In most cases that will be enough, but calls to any APIs
1065 that take a pointer to image sizes may need source changes.
1067 - you should be able to create very large images on 64-bit systems,
1068 if you have enough memory. Successfully created a 32768 x 49192 x
1069 3 channel image, filled with a tiled image and scaled it. The
1070 unscaled image was also successfully saved to a JPEG.
1072 - check the image size before attempting to write BMP, GIF, JPEG,
1073 PNG, SGI, TGA, TIFF images.
1075 - correctly handle reading TGA images over 32767 pixels wide or tall.
1079 - the gif_left and gif_top tags are now clamped to non-negative
1080 values when writing a GIF image.
1082 - removed dead callback read/write code
1084 The default maximum memory size when reading files is now 1G.
1086 Imager 0.84 - 20 Jun 2011
1089 - Imager no longer inherits from Exporter (unless you're running an
1092 - Imager can now write progressive JPEGs (it could always read them).
1093 https://rt.cpan.org/Ticket/Display.html?id=68691
1097 - re-work, document and test Imager's logging facility.
1098 https://rt.cpan.org/Ticket/Display.html?id=65227
1100 - fix META.yml testing and the generated META.yml
1101 https://rt.cpan.org/Ticket/Display.html?id=65235
1103 - test and add error reporting to to_*() family methods
1105 - add to_rgb_double() method.
1106 https://rt.cpan.org/Ticket/Display.html?id=65101
1108 - Imager no longer exports anything by default
1109 https://rt.cpan.org/Ticket/Display.html?id=65228
1111 - convert colors to grayscale if the supplied (or generated) palette
1112 contains only grays when performing error diffusion color
1114 https://rt.cpan.org/Ticket/Display.html?id=68508
1116 - writing a paletted image to GIF wouldn't always use the colors
1117 supplied (or generated, eg. via make_colors => "mono"), which was
1119 https://rt.cpan.org/Ticket/Display.html?id=67912
1121 - replace (imager|tony)@imager.perl.org in the doc, since I don't
1122 plan to continue receiving mail at that address.
1123 https://rt.cpan.org/Ticket/Display.html?id=68591
1125 Imager 0.83 - 21 May 2011
1130 - diag() the error message on failure for some TIFF tests that are
1131 failing on a Solaris smoker.
1132 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
1134 Imager 0.82_01 - 17 May 2011
1137 Dev release, in case the compose tests are too sensitive.
1141 - Imager::Font::T1 incorrectly checked for absolute filename under
1142 Win32. Thanks to kmx for the report and fix.
1143 https://rt.cpan.org/Ticket/Display.html?id=67963
1145 - compose() with the target, source or mask position off the top or
1146 left of the target image didn't clip the source image correctly.
1147 https://rt.cpan.org/Ticket/Display.html?id=67220
1149 - compose() now returns a useful error message on a non-positive
1152 - compose.im now at 100% test coverage. (As opposed to, umm, much,
1155 Imager 0.82 - 14 Mar 2011
1160 - eliminate calls to i_has_format() from the test suite, since it's
1161 no longer a useful way to check for file format support. Eliminate
1162 i_has_format() from the functions exposed via XS.
1163 https://rt.cpan.org/Ticket/Display.html?id=65863
1165 - eliminate calls to note(), which isn't in the (very old) version of
1166 Test::More we have as a pre-requisite. note() is modern enough
1167 that I don't feel a need to require a Test::More upgrade for it.
1168 https://rt.cpan.org/Ticket/Display.html?id=65864
1170 - skip the threads tests on Test::More 2.00_*
1171 https://rt.cpan.org/Ticket/Display.html?id=65812
1173 - add an (unshipped) test to check Imager's internal POD links
1174 https://rt.cpan.org/Ticket/Display.html?id=65749
1176 - improve the library detection summary
1177 https://rt.cpan.org/Ticket/Display.html?id=9675
1179 - increase the version of Imager::Font::Type1 so that upgrades don't
1180 downgrade the version in this file.
1181 https://rt.cpan.org/Ticket/Display.html?id=66250
1183 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
1184 that option for the directories that would normally go in
1185 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
1186 https://rt.cpan.org/Ticket/Display.html?id=65955
1188 Imager 0.81 - 14 Feb 2011
1191 - added coverage tests for masked images (maskimg.c @100% test coverage)
1193 - add hsv() method to Imager::Color
1194 Thanks to Leolo (Philip Gwyn)
1195 https://rt.cpan.org/Ticket/Display.html?id=65385
1197 - split libt1 Type 1 font support into a sub-module
1198 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1200 - add a preload() class method for use in forking servers, and to
1201 work around limitations in PAR.
1202 https://rt.cpan.org/Ticket/Display.html?id=65665
1206 - paletted writes to a masked image are now masked correctly.
1207 Revealed by new coverage tests.
1209 - update the filter plugin documentation.
1210 https://rt.cpan.org/Ticket/Display.html?id=56513
1212 - add the matrix() method to Imager::Matrix2d to allow creation of a
1213 matrix with specified co-efficients. You can now multiple an
1214 Imager::Matrix2d object by a 9 element array ref or a number.
1215 https://rt.cpan.org/Ticket/Display.html?id=29938
1217 - really fix loading TTF fonts with FT2 when FT1 isn't available.
1218 Thanks to Leolo (Philip Gwyn)
1219 https://rt.cpan.org/Ticket/Display.html?id=65386
1220 https://rt.cpan.org/Ticket/Display.html?id=62855
1222 - make sure each test script that needs testout/ creates it.
1223 https://rt.cpan.org/Ticket/Display.html?id=65088
1225 - handle a slightly different warning from libtiff 4.x
1226 https://rt.cpan.org/Ticket/Display.html?id=65268
1228 - the sat transform2() op returned an incorrect saturation.
1229 https://rt.cpan.org/Ticket/Display.html?id=65391
1231 Imager 0.80 - 17 Jan 2011
1234 - added coverage tests for Imager::Fountain and Imager::Color::Float
1236 - Imager is now maintained in git
1237 http://git.imager.perl.org/imager.git
1238 git://git.imager.perl.org/imager.git
1242 - images with an translucent alpha channel were not scaled correctly
1243 by the default (qtype=normal) scaling method.
1244 https://rt.cpan.org/Public/Bug/Display.html?id=63922
1246 - Imager::Color::Float now translates "#FFFFFF" to white instead of
1247 just a little darker.
1249 - make the default color map build algorithm "mediancut". This
1250 changes the default color map builder for writing GIFs back to what
1251 it was in 0.77, reverting a performance regression.
1252 https://rt.cpan.org/Ticket/Display.html?id=64785
1254 - handle failure to create a masked image correctly
1256 Imager 0.79 - 10 Dec 2010
1259 - add Imager::Test to the POD coverage tests and document the missing
1262 - the convert() method now optimizes the case where all output
1263 channels are either 0, sourced from a single input channel or 1.
1264 This significantly speeds up presets like "addalpha", "green".
1265 https://rt.cpan.org/Ticket/Display.html?id=51254
1267 - add wiggle.pl sample, as suggested by Dan Oppenheim.
1269 - add the combine() method to combine channels from multiple source
1270 images into a new image
1271 https://rt.cpan.org/Ticket/Display.html?id=11872
1275 - treat the co-efficients for convert() as doubles instead of floats.
1277 - If a higher (earlier) priority font handler failed to load, that
1278 would crash preventing loading of later font handlers.
1279 https://rt.cpan.org/Ticket/Display.html?id=62855
1281 - parse defines from the options returned by pkg-config --cflags
1282 https://rt.cpan.org/Ticket/Display.html?id=63223
1284 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
1285 included in the tarball. They are now included.
1287 Imager 0.78 - 4 Oct 2010
1292 - don't access deprecated members of the png_structp.
1293 https://rt.cpan.org/Ticket/Display.html?id=60242
1295 - document that using color objects is faster than supplying colors
1297 https://rt.cpan.org/Ticket/Display.html?id=61047
1299 - Imager::Probe now accepts array references for incpath and libpath.
1300 https://rt.cpan.org/Ticket/Display.html?id=60244
1302 Imager 0.77_02 - 27 Sep 2010
1305 - moved Win32, FreeType 2 font support into sub-modules.
1306 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1307 Uses Imager::Probe now.
1308 https://rt.cpan.org/Public/Bug/Display.html?id=61328
1310 - tested successfully with jpeg-8b
1311 https://rt.cpan.org/Ticket/Display.html?id=60221
1315 - from _01: look for missing file support test files in the right
1318 - flood_fill() wouldn't fill the right side of a single scan-line
1320 Thanks to Nicolas Roggli for reporting this.
1322 - flood_fill wouldn't fill to the left edge of the image if the
1323 starting line didn't reach the left edge.
1324 Thanks to Nicolas Roggli for reporting this.
1326 Imager 0.77_01 - 13 Sep 2010
1329 - add each library-directory/pkgconfig/ to the pkg-config search path
1331 Thanks to Justin Davis.
1332 https://rt.cpan.org/Ticket/Display.html?id=60491
1334 - moved GIF, TIFF, JPEG file handling code into sub-modules in
1335 preparation for separate distribution.
1336 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1338 Note: this removed support for libungif from Imager.
1340 - optimize filled box drawing (color, not fill)
1344 - Imager::Probe was calling ExtUtils::Liblist to initialize
1345 LD_RUN_PATH supplying an undefined value rather than the found
1346 directory. Thanks to Justin Davis.
1347 https://rt.cpan.org/Ticket/Display.html?id=60491
1349 - only prepend ./ to font filenames when passing them to T1Lib and
1350 then only when it would use its search mechanisms.
1351 https://rt.cpan.org/Ticket/Display.html?id=60509
1353 - fix the cache check for the X rgb.txt loader. This is typically
1354 used for color translation on Unix-like systems, and the fix
1355 improves performance of supplying colors by name by about 80 times.
1356 Test code that managed 3400 10x10 pixel boxes/second sped up to
1359 - clarify that Imager doesn't write EXIF metadata to images.
1360 https://rt.cpan.org/Ticket/Display.html?id=60637
1362 - Imager::Probe can now search subdirectories under its include path.
1363 Used by the PNG Makefile.PL to find headers and libraries when they
1364 aren't in the base directory, as in cygwin.
1365 https://rt.cpan.org/Ticket/Display.html?id=60635
1367 Imager 0.77 - 11 Aug 2010
1370 I don't want Imager::File::PNG indexed as part of Imager, but forgot
1371 to update the META.yml before updating the version.
1373 - don't index Imager::File::PNG as part of Imager
1375 - add resources to META.yml
1377 Imager 0.76 - not released
1382 - the align_string() method would ignore a string of "0" due to a
1383 mis-use of C< ||= >.
1384 Thanks to Maurice Height for reporting this.
1385 https://rt.cpan.org/Ticket/Display.html?id=60199
1387 Imager 0.75_03 - 09 Aug 2010
1392 - read_types() and write_types() would include png when it wasn't
1393 available due to a problem with the %formats tie
1395 - handle dependent libraries correctly (eg -lpng requiring -lz) in
1396 the code run phase of library probing.
1398 Imager 0.75_02 - 07 Aug 2010
1403 - add file missing from MANIFEST, which was causing TIFF failures.
1405 Imager 0.75_01 - 06 Aug 2010
1408 Test release for the new PNG probe.
1410 - added the ability to read multiple-image PNM files.
1411 Note that unlike the pbm/pgm/ppm specification this accepts mixed
1412 format files and allows white space padding between files.
1413 Thanks to Philip Gwyn (Leolo) for this patch.
1415 - moved the PNG file handling code into a sub-module in preparation
1416 for separate distribution.
1417 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1418 Also helps avoid complications from -I/-L compile/link options from
1423 - Imager->new(data => $data) didn't try to process image file data in
1425 https://rt.cpan.org/Ticket/Display.html?id=58761
1427 - t/t50basicoo.t no longer depends on the other tests to generate its
1429 https://rt.cpan.org/Ticket/Display.html?id=9798
1430 Also, it wasn't testing pnm (pnm vs ppm mix-up)
1432 - update the documentation of hardinvert to match the change in 0.62.
1433 https://rt.cpan.org/Ticket/Display.html?id=59785
1435 - added hardinvertall filter which also inverts the alpha channel
1436 (sorry for the mess)
1438 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
1439 the probe can find the library for the test run.
1440 https://rt.cpan.org/Ticket/Display.html?id=57518
1442 Imager 0.75 - 20 Jun 2010
1445 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
1446 perls (not measured)
1450 - an opacity fill based on a fountain fill would segfault when
1451 filling an 8-bit/sample image.
1453 - merge thickline branch polygon fix
1454 https://rt.cpan.org/Ticket/Display.html?id=43518
1456 Imager 0.74 - 7 May 2010
1461 - read_multi() didn't handle a missing file format library correctly,
1462 aborting on failing to call i_readgif_multi_wiol() or
1463 i_readtiff_multi_wiol().
1465 - fix spelling errors patched by Debian
1466 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
1468 - add an (unshipped) author test to spellcheck Imager's POD.
1470 - update the TIFF file format documentation
1471 https://rt.cpan.org/Ticket/Display.html?id=56510
1473 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
1475 Imager 0.73 - 15 Mar 2010
1478 - implement outline circles, both anti-aliased and not
1479 https://rt.cpan.org/Ticket/Display.html?id=19755
1481 - a combine => "none" fill to a 1 or 3 channel image would produce
1482 the incorrect colour.
1484 Imager 0.72 - 09 Dec 2009
1487 Bump version for release, since 0.71_03 is stable with CPAN testers.
1489 Imager 0.71_03 - 5 Dec 2009
1492 - further adjust the threads test so it only performs the tests on
1493 perls where it's expected to work, and only if the threads module
1496 Imager 0.71_02 - 1 Dec 2009
1499 - adjust the way we load the threads module for the threads test so
1500 it works with non-threaded perls
1502 Imager 0.71_01 - 30 Nov 2009
1507 - use scanline oriented operations to flip images instead of pixel
1509 https://rt.cpan.org/Ticket/Display.html?id=39278
1511 - use double/sample operations to flip large sample images instead of
1512 8-bit sample operations.
1513 https://rt.cpan.org/Ticket/Display.html?id=39280
1516 https://rt.cpan.org/Ticket/Display.html?id=51874
1518 - prevent double-frees when someone creates Imager objects and then
1519 creates a thread. Note: this just handles some simple cases,
1520 Imager doesn't support perl threads, and isn't likely to.
1521 https://rt.cpan.org/Ticket/Display.html?id=52268
1523 Imager 0.71 - 16 Nov 2009
1526 - add the opacity fill type - an adaptor that modifies the opacity of
1531 - the conv filter now enforces that the sum of the coefficients is
1532 non-zero. Also, rather than skipping pixels off the edge off the
1533 edge of the image, the closest edge pixel is used. Previously
1534 dividing by the zero sum of coefficients could cause invalid
1535 results or runtime exceptions.
1536 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
1539 Imager 0.70 - 21 Sep 2009
1544 - release image row and comments memory on all error returns in gif
1547 - handle zero length extensions, previously this would cause a null
1549 Thanks to Krzysztof Wojtaś for the test data and fix for this.
1551 - an integer division meant that preview scaling to below 1 pixel
1552 wide or high (which isn't too useful anyway) was calculating using
1553 NaNs on most platforms, and causing an exception on others.
1554 Thanks to David Cantrell for producing a backtrace of the crash on
1555 his Alpha-NetBSD CPAN test box which made it possible to track this
1558 Imager 0.69 - 08 Sep 2009
1563 - broken test fix - was attempting to call a function skip_all, when
1564 that should be a parameter to plan().
1566 - briefly document apidocs.perl, the tool used to build
1567 Imager::APIRef and make some minor enhancements
1569 - various minor documentation enhancements and fixes.
1571 Imager 0.68 - 07 Sep 2009
1574 - Imager->new(file => $filename) and other similar incantations will
1575 load the given file.
1576 https://rt.cpan.org/Ticket/Display.html?id=48261
1580 - avoid using CHECK as a label in Imager::Test
1581 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
1583 - re-work most image file test files that require a library into
1584 separate library present/not present files to remove stupidly long
1587 - don't treat rubthrough() outside the bounds of the target image as
1589 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
1591 Imager 0.67_01 - 02 Sep 2009
1596 - correct documentation of default of raw image interleave read
1598 https://rt.cpan.org/Ticket/Display.html?id=42074
1600 - add raw_ prefix to raw read parameters, though the original names
1603 - fail the read if an invalid raw_interleave parameter is supplied
1605 - warn if no interleave or raw_interleave parameter is supplied,
1606 since the documented default was wrong, and incompatible with the
1609 - for reading raw images, if raw_storechannels > raw_datachannels,
1610 set the extra channels in the image to 0
1612 - when probing for executables like freetype-config, search for .bat
1613 and .cmd on MSWin32, as well as .exe.
1614 https://rt.cpan.org/Ticket/Display.html?id=49275
1616 - re-work the external libraries section of README:
1617 - list Debian and Redhat package names for each library
1621 - use the new EU::MM META_MERGE facility instead of generating
1622 META.yml from scratch
1623 https://rt.cpan.org/Ticket/Display.html?id=47888
1625 - use Devel::CheckLib (bundled, modified) to check which release of
1626 libtiff is installed and reject 3.9.0
1627 http://bugzilla.maptools.org/show_bug.cgi?id=2088
1628 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
1630 Imager 0.67 - 12 Dec 2008
1635 - fix a packaging error
1637 Imager 0.66 - 12 Dec 2008
1640 - 24-bit color .ICO/.CUR files can now be read.
1644 - an optimization skipping 0 src alpha values could cause the
1645 rubthrough() to read past the end of a buffer.
1646 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
1648 - corrected a reference leak where writing GIFs would leak memory.
1649 This could also happen calling to_paletted().
1650 Also documented the underlying long existing feature where the
1651 colors parameter is filled with the generated color table and added
1653 http://rt.cpan.org/Ticket/Display.html?id=41028
1655 - write out the image size in bytes field of a BMP correctly.
1656 http://rt.cpan.org/Ticket/Display.html?id=41406
1658 - add limited tests for Imager::ExtUtils
1660 - make Imager::ExtUtils->includes use an absolute path, since
1661 a relative path could cause failures using Inline::C.
1662 http://rt.cpan.org/Ticket/Display.html?id=37353
1664 - re-arrange the POD for Imager::Font::BBox:
1665 - mark total_width(), pos_width(), end_offset() obsolete, since
1666 they're mostly for backwards compatibility
1667 - group width methods and height methods
1668 https://rt.cpan.org/Ticket/Display.html?id=39999
1670 Imager 0.65 - 20 May 2008
1675 - In some cases when an error occurs reading those parts of a JPEG
1676 file after the image the scan-line buffer could be freed a second
1677 time. In cases where the the error occured while reading the image
1678 data it's possible that the buffer could have leaked.
1679 Thanks to Gabriel Vasseur for reporting this and help in tracking
1682 - the gif_screen_height tag was overriding the screen width and being
1683 ignored for the screen height when present.
1684 https://rt.cpan.org/Public/Bug/Display.html?id=35568
1686 Imager 0.64 - 23 April 2008
1689 This is a bug fix release. This includes a fix for a possible
1694 - Possible security issue: The floating point sample path for image
1695 based fills had a buffer overflow. This would overwrite the end of
1696 a malloc()ed buffer with double precision floats.
1697 http://rt.cpan.org/Ticket/Display.html?id=35324
1700 - check that the result of fileno($fh) is defined rather than simply
1701 true when read() or write() is supplied with an fh parameter.
1702 http://rt.cpan.org/Ticket/Display.html?id=35139
1704 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1705 resulting in a SIGSEGV when attempting to scale an image to a size
1706 too large to fit in memory. This is a NULL pointer access issue,
1707 not a buffer overflow.
1708 Added a check for the failure.
1709 scale_calculate() (and hence scale()) will now fail if any of the
1710 scale size parameters are a reference.
1711 http://rt.cpan.org/Ticket/Display.html?id=35172
1713 - Regression: filling a greyscale image with a hatch used the wrong
1714 color channels from the supplied fg/bg colors.
1715 https://rt.cpan.org/Ticket/Display.html?id=35278
1717 - fixed a related problem for image fills.
1719 Imager 0.63 - 7 April 2008
1722 This release primarily contains changes to improve ease of use -
1723 rather than you having to convert images to the appropriate number of
1724 channels, Imager handles it internally. How to handle drawing colors
1725 and the default combine mode is a thornier problem left for some other
1728 - the font libraries are now only initialized when needed.
1729 http://rt.cpan.org/Ticket/Display.html?id=28825
1731 - moved the imtoc.perl code into Imager::Preprocess
1733 - paste() and rubthrough() now adapt the source image data to the
1734 destination, so you can now safely paste/rubthrough from greyscale
1735 images to color images or back, or from alpha channel images to
1736 noalpha channels or back.
1737 https://rt.cpan.org/Ticket/Display.html?id=30908
1739 - rubthrough() now falls back to pasting when the source doesn't have
1740 an alpha channel. This effectively treats the source as having a
1741 max alpha channel, the right thing to do.
1742 http://rt.cpan.org/Ticket/Display.html?id=29944
1744 - re-worked most of the area filling code to use a common set of
1745 functions when filling.
1746 Corrected normal combine mode.
1747 Rewrote most of the combine modes to match the way the SVG draft
1748 defines them with respect to a translucent source and destination.
1749 Added tests for translucent source and destination.
1750 Added tests to check 8-bit/sample and double/sample combines work
1752 https://rt.cpan.org/Ticket/Display.html?id=29879
1754 - writing a 2 or 4 channel image to a JPEG file will now write that
1755 image as if composited against a background, black by default,
1756 overridable with the i_background tag/parameter.
1757 https://rt.cpan.org/Ticket/Display.html?id=29876
1759 - writing a 2 or 4 channel image to a PGM/PPM file will now write
1760 that image as if composited against a background, black by default,
1761 overridable with the i_background tag/parameter.
1762 http://rt.cpan.org/Ticket/Display.html?id=30074
1764 - writing a 2 or 4 channel image to a BMP file will now write that
1765 image as if composited against a background, black by default,
1766 overridable with the i_background tag/parameter.
1767 http://rt.cpan.org/Ticket/Display.html?id=30075
1771 - Imager::Matrix2d->translate() now only requires one of the x or y
1773 http://rt.cpan.org/Ticket/Display.html?id=29937
1775 - mixing qtype scaling now sets all channels of a pixel to zero if
1776 the pixel has zero coverage (zero alpha). This should produce more
1777 compressible output files.
1778 http://rt.cpan.org/Ticket/Display.html?id=32324
1780 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
1782 https://bugzilla.redhat.com/show_bug.cgi?id=166254
1783 I'm not changing the #! lines of the sample code, since it's sample
1784 code, not intended for installation.
1785 http://rt.cpan.org/Ticket/Display.html?id=33408
1787 - some TGA images weren't being detected correctly as TGA images
1788 https://rt.cpan.org/Ticket/Display.html?id=32925
1790 - handling of the left-over bit for 16-bit/pixel TGA images has been
1791 changed to match the behaviour of the GIMP. Previously the bit
1792 being set was treated as an opaque pixel, but one user reported a
1793 problem with loading such an image. I haven't been able to find any
1794 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1795 I'll match it's behaviour. See issue 114913 in the GIMP's
1797 http://rt.cpan.org/Ticket/Display.html?id=32926
1799 Imager 0.62 - 10 December 2007
1802 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
1803 to /path under your home directory.
1804 http://rt.cpan.org/Ticket/Display.html?id=29484
1806 - the old dynaload code used Mach API functions to load dynamic
1807 libraries on Mac OS X. These APIs have been deprecated in OS X
1808 10.5 and were causing some build problems.
1809 So henceforth Imager uses the dlopen() family of functions, and you
1810 will need version 10.3 or later of OS X.
1812 - added the det() function to the transform2() engine.
1813 added the sample quad_to_square.pl
1814 Courtesy Richard Fairhurst.
1815 http://rt.cpan.org/Ticket/Display.html?id=31244
1819 - samples/gifscale.pl sourced the base value for gif_top from
1821 Thanks to Eleneldil G. Arilou for pointing this out.
1823 - t/t82inline.t no longer loads B at runtime, to work around a bug
1824 in some 5.005_0[45] installations.
1825 http://rt.cpan.org/Ticket/Display.html?id=30508
1827 - work around Module::Depends::Intrusive bug #21229
1828 http://rt.cpan.org/Ticket/Display.html?id=30520
1830 - the hardinvert filter no-longer inverts the alpha channel.
1831 http://rt.cpan.org/Ticket/Display.html?id=30002
1833 - the hardinvert filter now supports large samples
1835 Imager 0.61_02 - 28 November 2007
1838 - major TIFF support re-work
1839 http://rt.cpan.org/Ticket/Display.html?id=20329
1841 - added a C level image interface for accessing samples from 1-32
1842 bits, exposed this at the perl level in getsamples()
1844 - the conv filter now works at floating point precision for high bit
1847 - added is_bilevel method to test whether an image should be written as
1848 a bilevel image if the image format supports it.
1850 - added -log-stderr as an Imager import list option
1852 - added some important types to Imager::APIRef
1854 - added test_image_double() to Imager::Test
1858 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
1861 - the scale() method with qtype mixing now handles images with an
1862 alpha channel correctly.
1864 - fixed a broken link from the "animated GIF" entry in the concept index.
1865 Thanks to Slaven Rezic.
1866 http://rt.cpan.org/Ticket/Display.html?id=30889
1868 - on some perl's the infix expression parser test would fail due to
1869 actions in the grammar returning false. Made sure all actions return
1871 Thanks to Richard Fairhurst for spending a lot of time in tracking
1873 http://rt.cpan.org/Public/Bug/Display.html?id=29562
1875 Imager 0.61 - 5 November 2007
1878 - added samples/gifscale.pl, which adjusts the screen size/position tags
1879 when scaling an animated gif
1880 http://rt.cpan.org/Ticket/Display.html?id=27591
1884 - correct handling of sz in matrix_transform() - this should allow
1885 perspective type transformations to work now.
1886 http://rt.cpan.org/Ticket/Display.html?id=29936
1888 - prevent a cast to integer warning on x64 builds in datatypes.c
1889 also fixed some other type warnings
1890 https://rt.cpan.org/Ticket/Display.html?id=30204
1892 - some sub-directory tests depended on files produced by the parent
1894 http://rt.cpan.org/Ticket/Display.html?id=30203
1896 - Imager::Font::Wrap doesn't correctly set savepos
1897 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
1898 http://rt.cpan.org/Ticket/Display.html?id=29771
1900 - test 171 in t/t01introvert.t was failing on perls configured to
1902 http://rt.cpan.org/Ticket/Display.html?id=29413
1904 - the code for the transform2() uminus operator was missing a break.
1905 Added tests for better code coverage of the ops.
1906 http://rt.cpan.org/Ticket/Display.html?id=29296
1908 - the SGI RLE compression code could overflow its compression buffer
1909 http://rt.cpan.org/Ticket/Display.html?id=30334
1911 - the 32-bit output function used by the SGI code only handled values
1912 under 0x10000. This was most noticable when writing large RLE images.
1913 http://rt.cpan.org/Ticket/Display.html?id=30335
1915 - validate chan_count for chans == NULL for each of the i_gsamp()
1917 http://rt.cpan.org/Ticket/Display.html?id=28985
1919 - attempt to work around the test failure at
1920 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
1921 http://rt.cpan.org/Ticket/Display.html?id=29562
1923 - improve the error messages produced when attempting to read or write
1924 an unknown image file format.
1925 http://rt.cpan.org/Ticket/Display.html?id=30103
1927 - improve the transform2() documentation
1928 http://rt.cpan.org/Ticket/Display.html?id=29267
1930 - correctly generate the author key in META.yml
1931 http://rt.cpan.org/Ticket/Display.html?id=30377
1933 - correctly blend a rotated (or matrix_transformed()) image when
1934 performing interpolation in the presence of an alpha channel.
1935 Also corrected the centring of the rotated image on the output
1938 Imager 0.60 - 30 August 2007
1941 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
1942 now has full SGI RGB image format, including RLE and 16-bit/sample
1944 https://rt.cpan.org/Ticket/Display.html?id=8666
1946 - logging functions are now available in the API
1948 - applied Gabriel Vasseur's patch
1949 added documentation, further tests, and support for greyscale images
1950 Obviously problems are my fault :)
1951 https://rt.cpan.org/Ticket/Display.html?id=28142
1953 - the mask for ICO/CUR images is now applied as an alpha channel to
1954 the returned image. For the old behaviour, supply ico_masked => 0
1955 to read() or read_multi(). This should be less confusing when
1956 using Imager as a general image processor.
1957 https://rt.cpan.org/Ticket/Display.html?id=29001
1961 - in some cases it's possible for giflib/libungif to return color
1962 indexes outside the range of colors defined by the image's palette.
1963 We now expand the palette to match the indexes used.
1964 Thanks to Gabriel Vasseur for reporting this.
1966 - fixed various memory leaks that could occur when failing to read png,
1967 jpeg, bmp or tga files.
1969 - to avoid confusion, channels not present in the image are returned as
1970 zero by getscanline(). This has no effect on the C level i_glin()
1971 and i_glinf() API functions which continue to not set the unused
1974 - the convert() method now returns an image of the same sample size as
1976 https://rt.cpan.org/Ticket/Display.html?id=28492
1978 - remove repeated text in Imager::Files
1979 http://rt.cpan.org/Ticket/Display.html?id=27589
1981 - be even more explicit that scale() and friends don't modify the source
1982 image, but return a new image.
1983 http://rt.cpan.org/Ticket/Display.html?id=28570
1985 - improve the error message from errstr() when you try to load a font
1986 for which the driver hasn't been built in Imager.
1987 http://rt.cpan.org/Ticket/Display.html?id=27571
1989 - transparency is now enabled by default when writing GIF images
1990 http://rt.cpan.org/Ticket/Display.html?id=27615
1992 - Imager would not load on Windows 98
1993 http://rt.cpan.org/Ticket/Display.html?id=27653
1995 Imager 0.59 - 14 June 2007
2000 - fixes a regression introduced by the fixes for RT 11972
2001 http://rt.cpan.org/Ticket/Display.html?id=27546
2003 - cropping outside the image would return an Imager object with
2004 no low-level image object, instead of returning false.
2005 Fixed by: Philip Gwyn (Leolo)
2006 http://rt.cpan.org/Ticket/Display.html?id=27509
2008 Imager 0.58 - 16 May 2007
2011 No significant changes from 0.57_01.
2013 Imager 0.57_01 - 11 May 2007
2016 - added to_rgb16 to produce a 16-bit/sample version of an image
2018 - improve freetype 1.x text output efficiency
2022 - search another place for rgb.txt, and check all the places
2023 Imager::Color checks when deciding whether to skip testing it
2024 http://rt.cpan.org/Ticket/Display.html?id=26064
2026 - use a convolution kernel size based on the stddev rather than a
2027 fixed size when performing a gaussian blur
2028 http://rt.cpan.org/Ticket/Display.html?id=25645
2030 - document the difference() method's mindist parameter, and debug it.
2032 - put the Imager release number in the Inline::C generated code to
2033 regenerate Inline code when a new release of Imager is installed.
2034 http://rt.cpan.org/Ticket/Display.html?id=26278
2036 - fix rendering on alpha channel images for the FreeType 1.x driver.
2037 http://rt.cpan.org/Ticket/Display.html?id=11972
2039 - fix rendering on alpha channel images for the T1lib driver.
2040 http://rt.cpan.org/Ticket/Display.html?id=11972
2042 - reworked library probing, we can now set more than one probe
2043 function for a library. Disabled the default (non-freetype-config)
2044 library probe and added an extra probe function that searches for
2045 both ft2build.h and whatever it includes, and adds -I as needed.
2046 Hopefully this will fix build problems like
2047 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
2048 http://rt.cpan.org/Ticket/Display.html?id=26086
2050 Imager 0.57 - 30 Apr 2007
2053 This is a maintenence release fixing a security issue in Imager.
2055 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
2056 overflow in malloced memory. There will be further discussion of
2057 this issue in the ticket below.
2058 http://rt.cpan.org/Ticket/Display.html?id=26811
2059 CVE-2007-2459 CVE-2007-2413
2060 The descriptions at cve.mitre.org varied in quality, please see the
2061 ticket at rt.cpan.org for a more accurate description of the issue.
2063 Imager 0.56 - 1 Apr 2007
2066 - added support for reading 16-bit/sample PGM/PPM images
2068 - added support for writing 16-bit/sample PGM/PPM images
2070 - improved performance of reading PBM/PGM/PPM images
2072 - added support for writing PBM images if the image is paletted and
2073 contains only black and white
2075 - added a new make_colors value - "mono"
2077 - switched from the svn log Changes to a manual Changes to reduce
2080 - new sample code - samples/flasher.pl
2084 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
2085 was returning an image object with an extra reference, this
2086 resulted in a memory leak.
2087 http://rt.cpan.org/Ticket/Display.html?id=24992
2089 - fix rendering on alpha channel images for the FreeType 2.x driver
2090 http://rt.cpan.org/Ticket/Display.html?id=11972
2092 - reading bmp files now consitently handles short reads. You can now
2093 supply a parameter to treat a short read as successful and set
2095 http://rt.cpan.org/Ticket/Display.html?id=8426
2097 - previously, reading ASCII PBM files required spaces between samples,
2098 even though the format doesn't require that
2100 - improved documentation of the unsharpmask filter (I hope)
2101 http://rt.cpan.org/Ticket/Display.html?id=25531
2103 - force flushing of the output from i_tt_dump_names() and test output
2104 in t/t35ttfont.t to prevent output from being mixed up.
2105 https://rt.cpan.org/Ticket/Display.html?id=24859
2107 - rewrite a conditional expression as an if() to hopefully work around
2108 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
2109 https://rt.cpan.org/Ticket/Display.html?id=25561
2111 - avoid Data::Dumper in regops.perl to support older releases of perl
2112 https://rt.cpan.org/Ticket/Display.html?id=24391
2114 Imager 0.55 - 16 Dec 2006
2117 This is primarily a bug fix release.
2119 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2121 There is one new feature:
2123 - the Win32 font driver now supports UTF8 (RT 22166)
2124 http://www.cpanforum.com/threads/3276
2125 http://rt.cpan.org/Ticket/Display.html?id=22166
2127 Several bugs were fixed:
2129 - the string() method would not output the string "0"
2130 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2132 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2133 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2135 - the gif_disposal and gif_user_input tags weren't being read from
2137 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2139 - gif.c was failing to build under MSVC
2140 http://rt.cpan.org/Ticket/Display.html?id=23922
2142 - in some cases strings passed to the string() method were treated as
2143 terminated by NUL (chr 0)
2144 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2146 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2147 that's the default build name for zlib on Win32.
2148 http://rt.cpan.org/Ticket/Display.html?id=23064
2150 - search $Config{incpath} for headers too, which we should have been
2153 Win32 font driver fixes:
2155 - the global descent value from bounding box was the wrong sign
2156 http://www.cpanforum.com/threads/3276
2158 - if the first or last glyph overflowed the left or right side of the
2159 advance width they would be clipped
2162 Imager 0.54 - 14 Sep 2006
2165 This is primarily a feature release:
2167 - a new qtype value 'mixing' has been added to the scale()
2168 method. This is faster than 'normal', slower than 'preview'. This
2169 is based on the method used by pnmscale, and seems to produce less
2170 blurry results than normal.
2171 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2173 - the rubthrough() method can now render onto images with an alpha
2175 http://rt.cpan.org/Ticket/Display.html?id=20678
2177 - the read_multi() method now falls back to calling doing a single
2178 image read via the read() method and write_multi() will now fall
2179 back to calling write() if a single image is supplied. This means
2180 you can simply call the read_multi() or write_multi() functions
2181 without having to check if the type is formatted by that method.
2182 http://rt.cpan.org/Ticket/Display.html?id=19457
2183 http://rt.cpan.org/Ticket/Display.html?id=19458
2185 - the GIF loop extension can now be written. If you don't have
2186 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2188 http://rt.cpan.org/Ticket/Display.html?id=21185
2190 - getscanline() and setscanline() can now read/write palette index
2191 based data from/to the image for paletted images, by setting type to
2193 http://rt.cpan.org/Ticket/Display.html?id=20338
2195 - we no longer hassle you to disable GIF support
2196 http://rt.cpan.org/Ticket/Display.html?id=20687
2198 - minor documentation fixes
2201 Imager 0.53 - 26 Jul 2006
2204 This is a bugfix release.
2206 Some test code was left in a code path not covered by the test
2207 suite. A test was added to cover this code path and the test code was
2209 http://rt.cpan.org/Public/Bug/Display.html?id=20705
2212 Imager 0.52 - 25 Jul 2006
2215 This is primarily a feature release, but contains a fair few bug
2216 fixes, new features:
2218 - ability to read and write MS Windows ICO and CUR files
2220 - you can now add file format plugins to support new file formats
2222 - add POD coverage tests
2224 - setcolors() and addcolors() now accept color names and so on
2225 instead of requiring Imager::Color objects.
2226 http://rt.cpan.org/Ticket/Display.html?id=20056
2228 - flood_fill() can now fill to a specified border color instead of
2229 just to the area the same color as the seed.
2230 http://rt.cpan.org/Ticket/Display.html?id=19618
2235 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2236 calculating the advance width.
2237 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2239 - bounding_box for the T1 driver wasn't including leading and
2240 trailing spaces in the bounding box as the other drivers did, it also
2241 produced strange results for empty strings or strings containing only
2244 - when reading CMYK jpeg images they were being transferred to the
2245 image object as is, producing a four channel image. It only looked ok
2246 due to an old still unfixed Photoshop bug. We now convert from the
2247 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2248 http://rt.cpan.org/Ticket/Display.html?id=20416
2250 - reading a CYMK TIFF would result in a 4 channel image, reading any
2251 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2253 http://rt.cpan.org/Ticket/Display.html?id=20415
2255 - added /usr/local/include to the default include search path, since
2256 we were already searching /usr/local/lib for libraries.
2258 And various minor fixes and documentation updates.
2261 Imager 0.51 - 23 Apr 2006
2264 - fix a validation bug when processing JPEG EXIF data that can cause
2266 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2268 - fix mis-processing of the src_maxx and src_maxy parameters of the
2270 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2272 - fix a problem in Imager's "smart" handling of the color parameter
2274 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2277 Imager 0.50 - 29 Mar 2006
2280 - CRITICAL: fixes a segmentation fault from attempting to write a 2
2281 or 4 channel image to jpeg or a 2 channel image to tga where the
2282 output is an in-memeory buffer.
2283 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2285 - fixes an incorrect pointer parameter in the PNG code
2286 http://rt.cpan.org/Public/Bug/Display.html?id=18051
2288 - skip Inline::C tests when building in a directory with spaces
2289 http://rt.cpan.org/Public/Bug/Display.html?id=18049
