1 Imager release history. Older releases can be found in Changes.old
3 - Imager::Color::Table is now pre-loaded by the preload() method.
4 https://rt.cpan.org/Ticket/Display.html?id=104896
6 - fix an assertion triggered under perl 5.23.4.
7 Thanks to A. Sinan Unur for the report and the patch.
9 Imager 1.003 - 12 May 2015
12 - update 1.002 release notes to include the center change for filled
15 - flood_fill() would escape beyond a 4-connected space under some
17 Added many more flood_fill() tests.
18 https://rt.cpan.org/Ticket/Display.html?id=103786
20 Imager 1.002 - 3 Apr 2015
23 - drawing anti-aliased filled circles is now 10 to 50 times faster
24 depending on the size of the circle.
25 This also changed the center from being the center of the pixel to
26 being the top left of the pixel to match the filled arcs drawn by
28 https://rt.cpan.org/Ticket/Display.html?id=101682
30 - enhancements to polygon filling:
32 - added a mode parameter to control how overlapping regions behave
34 - added a polypolygon() method to fill more than one polygon at a
37 - polygon filling is now exposed through the API.
39 - added colormodel(), alphachannel() and colorchannels() methods.
40 These were added for two reasons:
42 - a future version of Imager may allow the number of channels in
43 an image to not directly represent the color model of an image.
44 eg. a greyscale TIFF image with multiple alpha channels.
46 - a future version of Imager may allow an image to be read without
47 translation, for example a TIFF file that contains measurements
48 from an instrument. Currently Imager transforms the samples into
49 the range 0.0 ... 1.0 which may means the user has to translates
52 An untranslated image would be unusable as image data, so
53 colormodel() would return "unknown" in this case.
55 Similarly a CMYK image might be returned as an "unknown" color
56 model image, if the caller chooses to disable translation to
59 Imager 1.001 - 2 Jan 2015
62 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
63 Thanks to Slaven Rezic for the report and the patch.
64 https://rt.cpan.org/Public/Bug/Display.html?id=98234
66 - GIF: clean-up a test file if the test for the giflib 4.2.0 file
69 - fix Imager::Matrix2d::rotate()'s centre point handling
70 https://rt.cpan.org/Public/Bug/Display.html?id=99959
72 - ICO: don't apply the icon mask to images with an alpha channel by
74 https://rt.cpan.org/Public/Bug/Display.html?id=99507
76 - make verbose probing output more verbose
78 - use Imager::Probe to probe for freetype 1.x
79 https://rt.cpan.org/Ticket/Display.html?id=100502
81 - The --enable and --disable parameters to the top-level Makefile.PL
84 - update the bundled/modified Devel::CheckLib to handle the gcc-4
87 Imager 1.000 - 28 Jul 2014
90 There's nothing special about Imager 1.000, it's just another release.
92 - fix the skip check for the iolayer qr// buffer test
94 - improve error reporting for the iolayer test failing on a small
95 number of Win32 CPAN testers
97 Imager 0.99_02 - 21 Jul 2014
100 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
101 the blue channel in the generated palette, and allow each color
102 component to be in the range 100..255 instead of just 100..254.
103 Thanks to Ralf Neubauer.
104 https://rt.cpan.org/Ticket/Display.html?id=97086
106 - revert "improved the XS for i_io_read() and i_io_raw_read()"
107 This caused problems with older perls and didn't provide much of a
108 performance improvement.
110 - support Inline 0.57 and later.
111 Inline 0.57 changed the "with" interface.
112 https://rt.cpan.org/Ticket/Display.html?id=97108
114 - don't define our own MAXINT macro, it conflicts with windows header
115 files and in a few places it was the wrong value to use anyway.
116 https://rt.cpan.org/Ticket/Display.html?id=96425
118 Imager 0.99_01 - 29 Jun 2014
121 - GIF: add support for giflib 5.1.0, which added error code pointer
122 parameters to EGifCloseFile() and DGifCloseFile().
123 https://rt.cpan.org/Ticket/Display.html?id=96756
125 - GIF: avoid a double-free when do_write() fails.
127 - fix SV type probing to work on perl before 5.12. Broken in 0.99.
128 https://rt.cpan.org/Ticket/Display.html?id=96761
130 - PNG: skip the benign error test before libpng 1.6.0, since the
131 error we're testing didn't exist before 1.6.0.
132 https://rt.cpan.org/Ticket/Display.html?id=94717 (continued)
134 Imager 0.99 - 25 Jun 2014
137 - Imager::IO->new_buffer() (and hence Imager->read()'s data
138 parameter) now accepts a reference to a scalar as well as just a
140 https://rt.cpan.org/Ticket/Display.html?id=92785
142 - Imager::IO->new_buffer() now always makes a copy of the passed in
143 buffer to avoid problems with temporary objects used for the return
145 https://rt.cpan.org/Ticket/Display.html?id=92785
147 - improved the XS for i_io_read() and i_io_raw_read()
148 https://rt.cpan.org/Ticket/Display.html?id=92738
150 - load plugins from absolute paths on Android
151 Thanks to Brian Fraser.
152 https://rt.cpan.org/Ticket/Display.html?id=93272
154 - added the jpeg_optimize parameter for writing JPEG files. This can
155 significantly reduce file sizes, but uses more memory and time.
156 https://rt.cpan.org/Ticket/Display.html?id=94292
158 - the autolevels filter now works on the luminosity of the image
159 rather then working per channel. The old autolevels filter is
160 still available as "autolevels_skew".
161 https://rt.cpan.org/Ticket/Display.html?id=94413
163 - Imager::File::PNG now supports libpng 1.6.10.
164 1.6.10 changed CRC errors from benign errors to normal errors,
165 which broke the test which used CRC errors to check for benign
166 error support. Switched to using a 1-bit grey-scale image with a
167 palette to test for benign errors.
168 https://rt.cpan.org/Ticket/Display.html?id=94717
170 Imager 0.98 - 3 Jan 2014
173 Incompatible changes:
175 - the return value of setpixel() has changed.
177 Previously the return values for undrawable pixels vs caller errors
178 changed depending on whether you used the multiple pixel calling
179 mechanism, or the single pixel mechanism.
183 - for an invalid parameter, such as an unknown colour, or missing
184 parameter, an empty list (or undef in scalar context) is
185 returned, and errstr() is set,
187 - otherwise the number of pixels drawn is returned. If none of
188 the pixels could be drawn (they were all outside the image), "0
189 but true" is returned.
191 https://rt.cpan.org/Ticket/Display.html?id=87650
195 - when drawing on an image with an alpha channel where the source
196 minimum is greater than zero, Imager would read from beyond the end
197 of a malloc() allocated buffer. In rare circumstances this could
198 lead to some of the source image not being written to the target
199 image, or possibly to a segmentation fault.
200 I don't believe this has any security concerns beyond that.
202 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
203 text drawn would be nonsense. This would also read beyond the end
204 of a malloced buffer.
206 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
208 https://rt.cpan.org/Ticket/Display.html?id=88993
210 - Imager::Font::Wrap no longer requires the image parameter.
211 https://rt.cpan.org/Ticket/Display.html?id=87338
213 - a documentation typo fix in Imager::Transformations
214 Thanks to Adrian Yee.
215 https://rt.cpan.org/Ticket/Display.html?id=88598
217 - Image::Probe, Imager's internal module for probing library
218 locations now searches the directories specified by LD_RUN_PATH,
219 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
220 and the corresponing s/\blib$/include/ directories for header
222 https://rt.cpan.org/Ticket/Display.html?id=86428
224 Imager 0.97 - 15 Jul 2013
227 No changes from 0.96_02.
229 Imager 0.96_02 - 8 Jul 2013
232 - PNG: treat a version mismatch between headers and library as a
234 https://rt.cpan.org/Ticket/Display.html?id=86659
236 - PNG: the check for benign error support is more complex than a
237 simple library version check, check for the appropriate macro.
238 Thanks for Slaven Rezic for following up on my CPAN Testers result
240 https://rt.cpan.org/Ticket/Display.html?id=86659
242 - W32: add a missing head1 AUTHORS to the old Win32.pm
243 https://rt.cpan.org/Ticket/Display.html?id=86658
245 Imager 0.96_01 - 1 Jul 2013
248 - TIFF: handle SampleFormat = 2 by translating the signed integer
249 values to unsigned by flipping their sign bits.
251 Handle SampleFormat = 3 where possible.
253 SampleFormat is ignored for paletted images.
255 Mixed SampleFormat are handled incorrectly, since libtiff returns
256 only the first SampleFormat value, and an image with both an alpha
257 channel and SampleFormat = 2 for color channels probably has a
258 different SampleFormat for the alpha channel.
260 https://rt.cpan.org/Ticket/Display.html?id=74540
263 https://rt.cpan.org/Ticket/Display.html?id=69243
265 - Imager::Color's rgba() method now returns its values as integers
266 instead of floating point. (IV instead of NV).
268 - The XS for i_map() and i_matrix_transform() now use the AV *
269 typemap instead of rolling their own.
271 - The XS for DSO_call() now uses the HV * typemap instead of
274 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
275 i_gradgen() now use a new T_AVARRAY typemap that greatly
276 simplifies the XS code.
278 - many other minor XS changes
280 - some XS code formatting
282 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
283 now renders in alpha-combining mode, to match antialiased output.
284 https://rt.cpan.org/Ticket/Display.html?id=73359
286 - add sample code and cookbook notes for drawing a blurred drop-shadow.
288 - add support for libpng 1.6, which changed the defaults for
289 reporting some types of error.
290 https://rt.cpan.org/Ticket/Display.html?id=85746
292 - FT2: use gsamp/psamp() to transfer pixels from the work image to
293 the output image instead of gpix/ppix.
294 https://rt.cpan.org/Ticket/Display.html?id=83478
296 - eliminate various GCC warnings, mostly initialized but otherwise
299 Imager 0.96 - 19 May 2013
302 - rearrange Imager's test files.
303 https://rt.cpan.org/Ticket/Display.html?id=84596
305 - Imager::Probe::_gcc_lib_paths now forces C locale.
306 A sufficiently recent gcc prints localized keys for the search
307 paths, which avoids that localization.
308 https://rt.cpan.org/Ticket/Display.html?id=84963
310 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
311 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
313 https://rt.cpan.org/Ticket/Display.html?id=85262
314 reported by Andreas König
316 - add a test for unclosed POD in C source, and fix the errors it
318 https://rt.cpan.org/Ticket/Display.html?id=74875
320 - fix some spelling errors detected by the newer aspell in Debian
323 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
324 thanks to gregor herrmann <gregoa@debian.org>
325 https://rt.cpan.org/Ticket/Display.html?id=85413
327 - add a test for standard =head1 commands and fix the errors found
329 Imager 0.95 - 19 Apr 2013
332 - handle the SVf_UTF8 flag correctly on magic strings passed to
333 Imager::IO's write() and raw_write() methods.
334 This may misbehave in perl 5.6.x since the UTF8 flag may not be
335 visible in the main SV after SvGETMAGIC().
336 https://rt.cpan.org/Ticket/Display.html?id=83438
338 - document that bounding_box() ignores the transformation matrix
339 supplied to tranform() for fonts.
340 https://rt.cpan.org/Ticket/Display.html?id=84106
342 Imager 0.94_02 - 5 Apr 2013
345 - enable debug logging for the standard font tests
347 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
348 due to a bug in that version of perl.
350 - don't test for read() failing on a write-only handle in 5.8.x and
351 earlier, this was fixed in change 862083f7e4 in perl.
353 - report the version of Inline found during testing (an attempt to
354 diagnose some intermittent failures.)
356 Imager 0.94_01 - 2 Mar 2013
359 - NOTE: possibly backward incompatible:
360 support reading from/writing to perl filehandes that aren't raw
363 This allows Imager's I/O to honour handles with layers such as
364 gzip, scalar file handles or tied file handles.
366 This is backward incompatible in that previous Imager would simply
367 use fileno() to retrieve the fd for the file and call write(2) etc
369 https://rt.cpan.org/Ticket/Display.html?id=78843
371 - moved most of README to lib/Imager/Install.pod which should make it
372 more accessible to the "web" generation, also significantly updated
375 - updated README's for the separately distributed modules to refer to
376 Imager::Install, and that they need -dev versions of packages
377 https://rt.cpan.org/Ticket/Display.html?id=81265
379 - the JPEG test code now reports the compile-time library version
381 - avoid a possible compiler optimization issue on CentOS 5.9 i386 by
382 rearranging (and mildly optimizing) some code.
383 https://rt.cpan.org/Ticket/Display.html?id=83212
385 - fix a POD error in Imager::Fill (detected on new Pod-Simple)
386 https://rt.cpan.org/Ticket/Display.html?id=83434
388 - fix a broken link to Graphics::Magick
389 https://rt.cpan.org/Ticket/Display.html?id=82743
391 - drawing text to a channel with FT2 would draw with random coverage
392 due to an uninitialized alpha channel.
394 - marked the function pointer underlying the mm_log() API with the
395 correct gcc magic and fixed the resulting warnings.
397 - fixed some other compiler warnings
399 - Imager::Font::W32 now properly reports text drawing errors
400 https://rt.cpan.org/Ticket/Display.html?id=70098
402 - handle the SVf_UTF8 flag correctly on magic (eg. overloaded)
403 strings passed as text to draw(), bounding_box(), has_chars(),
404 glyph_names() (where supported) in each of the font drivers.
405 This may misbehave in perl 5.6.x since the UTF8 flag may not be
406 visible in the main SV after SvGETMAGIC().
407 https://rt.cpan.org/Ticket/Display.html?id=83438 (partial)
409 Imager 0.94 - 15 Dec 2012
410 =========================
412 Variations on some of these changes were included in development
415 - improved thread safety
416 - the internal error stack and log file handle are now in a per-thread
418 - JPEG now captures IPTC information in a thread-safe way
419 - avoid globals where possible for warning capture in libtiff
420 - use a mutex to avoid re-entering thread-unsafe giflib
421 - use a mutex to avoid re-entering thread-unsafe tifflib
422 - use a mutex to avoid re-entering thread-unsafe T1Lib
423 - use a library handle per thread for freetype 2.
424 - use an engine handle per thread for freetype 1.x.
425 - originally these changes broke ABI compatibility, this has been
428 - clarify the return value of getpixel();
429 https://rt.cpan.org/Ticket/Display.html?id=81198
431 - fixed a race condition in parallel testing for T1
433 - fixed a bug in handling yoff for untransformed image-based fills
435 - documentation improvements for Imager::Fill
437 - FT2: report the library version while testing.
439 Imager 0.93 - 15 Oct 2012
444 - previously a transparency enabled GIF write (the default) would
445 always use a GIF89a header even if none of the images were
448 - previously the probe step for freetype-config would fail on cygwin
450 - catch an invalid matrix parameter to convert() instead of crashing
451 https://rt.cpan.org/Ticket/Display.html?id=79922
453 - remove the 16-bit/sample limitation from the documentation for
454 setsamples(), it hasn't applied for many releases.
455 https://rt.cpan.org/Ticket/Display.html?id=79989
457 - don't copy setsamples() data parameter, it may be a large scalar
458 https://rt.cpan.org/Ticket/Display.html?id=79990
460 - clean up .dSYM directories generated performing probes on OS X
463 - pass the --verbose command-line option through to Imager::Probe in
464 sub-module's Makefile.PLs
465 https://rt.cpan.org/Ticket/Display.html?id=75878
469 - support for giflib 5.0. (5.0.1 and later)
470 https://rt.cpan.org/Ticket/Display.html?id=79029
471 The giflib API Imager uses doesn't have a mechanism to set the
472 header version in 5.0.0.
474 - update the GIF library probe code to check for the new giflib 5.0.1
475 EGifSetGifVersion() function, and to check for the giflib 4.2.0
476 uninitialized gif89 bug.
477 https://rt.cpan.org/Ticket/Display.html?id=79679
478 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
480 - avoid static variables when capturing IPTC data from JPEG files
482 - match Imager::Font;:T1's error message translations to those from
483 later versions of T1Lib.
485 - for libtiff versions that support extended warning handlers (3.8.0
486 or later), use them to avoid some global variables.
488 - note Image::ExifTool for better metadata support.
489 https://rt.cpan.org/Ticket/Display.html?id=79251
491 Imager 0.92 - 14 Aug 2012
494 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
495 correctly for both probing and runtime.
496 https://rt.cpan.org/Ticket/Display.html?id=77672
498 - allow building JPEG/imexif.c on C89 compilers.
500 - allow building GIF/imgif.c on C89 compilers.
502 Imager 0.91 - 4 Jun 2012
507 - The size of rotated images is no longer rounded up so aggressively.
508 Added rounding to the linear interpolation done for rotate() and
509 matrix_transform() for 1 and 3 channel 8-bit images.
510 Adjusted the two tranlate matrices used to build the final rotation
511 matrix to use the distance between the outlier pixels rather than
512 the pixel dimensions (ie. dimension-1).
513 With all of this the output of rotate(degrees => 270) on an 8-bit
514 image exactly matches the output of rotate(right => 270).
515 https://rt.cpan.org/Ticket/Display.html?id=77063
519 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
520 internals, those names only matter for the XS interface.
522 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
523 the API level compiled into a loadable module such as
524 Imager::File::GIF doesn't match that of Imager. Previously it
525 could be difficult to determine exactly which module was failing to
527 https://rt.cpan.org/Ticket/Display.html?id=77173
529 - added Imager->check_file_limits() as an interface to the
530 i_int_check_image_file_limits() API.
532 - Imager->set_file_limits(reset => 1) now resets the limits to the
533 defaults rather than setting them all to unlimited.
535 - wrote a brief security note as Imager::Security
536 https://rt.cpan.org/Ticket/Display.html?id=68910
538 Imager 0.90 - 30 Apr 2012
543 - Imager::Test::is_imaged() attempted to process an "epsilon"
544 parameter but the prototype didn't allow for the extra parameter.
545 Corrected the prototype.
547 - when downconverting samples (eg. from floating point to 8 bit)
548 Imager now rounds the sample value rather than attempting to
549 allocate input values over output values equally. The old
550 behaviour had the probably surprising effect of converting a
551 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
553 This may result in slightly different 8 or 16-bit output images.
555 - BI_BITFIELD BMP images were handled incorrectly, both in
556 incorrectly calculating the space required for the masks and in
557 processing the image data itself.
558 https://rt.cpan.org/Ticket/Display.html?id=76736
560 - some odd width BMP BI_RLE4 images use run lengths that run one off
561 the edge of the image. Imager now allows this, discarding the
564 - odd length RLE4 runs in BMP images were decoded incorrectly.
566 - pkg-config could sometimes return a library that was in a directory
567 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
568 If no -L is included in the pkg-config library information check if
569 EU::MM can find the library, and if not, search our configured
570 directories and insert that into the library flags.
571 https://rt.cpan.org/Ticket/Display.html?id=75869
573 - Imager::Probe can now probe for libraries with dependent libraries,
574 common for static linking, eg. libpng requires libz.
575 https://rt.cpan.org/Ticket/Display.html?id=74043
577 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
579 - added alternative probe configurations that try to link libz, to
580 handle a statically linked libpng.
581 https://rt.cpan.org/Ticket/Display.html?id=74043
583 - if a probe includes testcode, Imager::Probe now checks that code as
584 part of the process of checking each configuration rather than as a
585 post test of the found configuration. This allows alternate
586 configurations to be checked if a matching but non-working
587 configuration is found.
588 https://rt.cpan.org/Ticket/Display.html?id=74043
592 - when reading or writing images via callbacks, the default callbacks
593 now push an error message indicating that a required callback was
594 called but not supplied.
595 https://rt.cpan.org/Ticket/Display.html?id=76782
597 - clarify which callbacks are required for reading and writing TIFF
600 - improve logging for creation of callback I/O layers.
602 - a little more documentation for Imager::Probe.
604 - the i_get_file_background() and i_get_file_backgroundf() APIs now
605 return int to indicate whether the i_background tag was found.
608 - improve error reporting
609 - add png_interlace, png_bits tags
610 - read paletted images as paletted images, including transparency
611 - read 1 bit greyscale images as a type suitable for other file
612 handlers to write as bilevel
613 - read 16 bit/sample PNG as 16-bit/sample Imager images
614 - write "bilevel" paletted images as 1 bit grayscale images
615 - write paletted images as paletted images
616 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
618 - improved metadata support
619 https://rt.cpan.org/Ticket/Display.html?id=29268
621 Imager 0.89 - 18 Mar 2012
626 - getpixel(..., type => "float") and the API i_gpixf() have been
627 broken on paletted images since they were implemented.
628 https://rt.cpan.org/Ticket/Display.html?id=75258
632 - links in the METHOD INDEX now point at the method documentation
633 rather than the heading you can find them under.
634 https://rt.cpan.org/Ticket/Display.html?id=71495
636 - Imager (and the bundled dynamic modules) no longer fallback to
637 using DynaLoader if loading via XSLoader fails.
638 For the bundled modules this could hide useful error messages.
639 https://rt.cpan.org/Ticket/Display.html?id=75560
641 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
642 buffer in the array of allocations, but just stores the filename
643 pointer and line number.
644 https://rt.cpan.org/Ticket/Display.html?id=70388
646 Imager 0.88 - 22 Feb 2012
649 - describe how to build libgif etc on OS X in such a way as to be
650 compatible with a fat binary perl (such as the system perl), in
652 https://rt.cpan.org/Ticket/Display.html?id=73371
654 - update the change notes for 0.77_01 to indicate that libungif
657 - add some other imaging modules to SEE ALSO
658 https://rt.cpan.org/Ticket/Display.html?id=73906
660 - note that the generator of the apparently non-DFSG-free postscript
661 in MMOne.pfb is a Debian package.
663 - setsamples() is now a true complement to getsamples() - it can
664 write 8-bit or floating point samples from a scalar or array
665 reference. This adds i_psamp() and i_psampf() to the C level API.
667 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
668 changed to make better use of the typemap, but these aren't part of
669 the perl level API anyway. There were no changes to the C level
670 interfaces to these functions.
672 - getpixel() and setpixel() now accept a mix of scalar and array
673 references for the x and y parameters, and unequal array lengths is
675 https://rt.cpan.org/Ticket/Display.html?id=73697
679 - correctly calculate the size of a rotated image
680 https://rt.cpan.org/Ticket/Display.html?id=69261
682 - fix incorrect rounding of color values for matrix_transform() and
684 https://rt.cpan.org/Ticket/Display.html?id=69261
686 - Win32 text output is now done in normal combine mode, the alpha
687 component of the color is now significant.
688 https://rt.cpan.org/Ticket/Display.html?id=70014
690 - remove long unused gif case from read()
691 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
693 - the getsamples() target parameter was being treated as a hashref
694 when it's meant to be an array reference.
695 https://rt.cpan.org/Ticket/Display.html?id=74882
697 - getpixel() and setpixel() now returns an empty list when invalid
698 parameters are supplied.
699 Invalid values for type now result in an error for getpixel().
700 https://rt.cpan.org/Ticket/Display.html?id=73697
702 Imager 0.87 - 03 Jan 2012
705 - document the return value of the filter() method.
706 https://rt.cpan.org/Ticket/Display.html?id=72369
708 - document i_gsamp_bits() and i_psamp_bits().
709 https://rt.cpan.org/Ticket/Display.html?id=68815
711 - properly increment the Imager::Matrix2d $VERSION.
713 - actually include the Imager::Test tests in the dist
715 - correctly read and write 256x256 pixel ICO files
716 https://rt.cpan.org/Ticket/Display.html?id=69599
718 - make the error message from read() or read_multi() when they can't
719 identify the file type match reality.
720 https://rt.cpan.org/Ticket/Display.html?id=72475
722 - read() now uses $FORMATGUESS if it can't determine the file type
723 based on the file header, to match read_multi().
725 - re-work and add tests for def_guess_type(). def_guess_type() no
726 longer returns any random file extension as the file type.
728 - add gray4, gray16 and gray as presets for make_colors.
729 https://rt.cpan.org/Ticket/Display.html?id=67911
731 - add make_palette() method that produces a palette from one or more
734 - fix the Imager dependency for the separately distributed font
736 https://rt.cpan.org/Ticket/Display.html?id=72643
738 - fix i_render_color() to properly draw in "normal" mode - ie. when
739 writing to a 1 or 3 channel image the second or fourth channel of
740 the source color was being ignored, it is now significant.
741 https://rt.cpan.org/Ticket/Display.html?id=71564
743 Imager 0.86 - 31 Oct 2011
746 - improve error reporting for W32 tests
748 Imager 0.85_02 - 24 Oct 2011
753 - eliminate unused i_gif_opts type (clean-up)
754 https://rt.cpan.org/Ticket/Display.html?id=69245
756 - fix combine=0 fill color anti-aliasing on the double/sample path
757 https://rt.cpan.org/Ticket/Display.html?id=71309
759 - make default text color non-transparent
760 https://rt.cpan.org/Ticket/Display.html?id=71469
762 - apply the last of the Debian unforwarded spelling fixes
763 https://rt.cpan.org/Ticket/Display.html?id=70656
765 - the log() method used its message parameter as a C level format
767 https://rt.cpan.org/Ticket/Display.html?id=71653
769 - provide our own STRLEN typemap entry for older perls.
770 https://rt.cpan.org/Ticket/Display.html?id=71641
772 - add extra ppport.h configuration to support older perls.
774 - depend on Scalar::Util, since we use it and older perls don't have
777 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
778 to synthesize it from overloaded "".
780 - use T1_StrError() for error messages on modern libt1
781 https://rt.cpan.org/Ticket/Display.html?id=69879
783 - actually load the font rather than just adding it to the catalog on
786 - Imager::Font->new now produces better error messages for the T1
789 - the font has_chars() method now returns perl's true and false
790 values in list context rather than integers, which should be more
792 https://rt.cpan.org/Ticket/Display.html?id=69158
794 - the btm data structure used by the flood_fill code is now
795 initialized more efficiently.
796 https://rt.cpan.org/Ticket/Display.html?id=68994
798 - updated the Thanks list in README
799 https://rt.cpan.org/Ticket/Display.html?id=71607
801 - check there's at least one coefficient for the convolution filter
802 https://rt.cpan.org/Ticket/Display.html?id=68993
804 - make the APIRef synopsis ordering consistent, older versions of
805 perl could order it differently.
806 https://rt.cpan.org/Ticket/Display.html?id=71675
808 - we rely on Config.pm's d_vsnprintf as to whether we use
809 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
810 though it only has _ prefixed versions of these. Define our own
811 prefixed names on Win32.
812 https://rt.cpan.org/Ticket/Display.html?id=71642
814 - fix library detection with MSVC
816 - search a few more library directories, so EU::MM doesn't discard
817 them. Hopefully fixes:
818 https://rt.cpan.org/Ticket/Display.html?id=71643
820 Imager 0.85_01 - 10 Oct 2011
823 - add simple tests for the Imager::Test test_image generators
825 - io_glue I/O buffering re-work:
827 - reorganize io_glue to do it's own buffering by default
829 - the unbuffered functions are available as i_io_raw_read() (or
830 raw_read() from perl) etc but are not recommended for typical
833 - use the new i_io_peekn() when checking for file magic to avoid
834 seek, allowing Imager to detect the file type and read the file
835 from an unseekable stream (for formats that don't use random
838 - added several new I/O layer API functions.
840 - fix the TGA performance problem, most noticably on Win32
841 https://rt.cpan.org/Ticket/Display.html?id=70037
843 - TIFF now uses wrapper functions of the correct types to avoid casts
844 https://rt.cpan.org/Ticket/Display.html?id=69912
846 - the callback IO object did its own buffering, controlled by the
847 maxbuffer parameter supplied to the read() and write() methods.
848 This buffering has been removed, to avoid redundancy with the
849 common io_glue buffering. This also avoids a bug in that code
850 which could rarely pass a zero length to the read callback and
851 then panic about the result.
853 - the callback IO object now tests the result of calling the close
854 callback, which should return true for success.
856 - the PNM reader did its own buffering. This buffering has been
857 removed to avoid redundancy with the common io_glue buffering.
859 - previously the read handlers for fd and callback I/O layers would
860 call the underlying interface (POSIX read or your supplied callback)
861 until it filled the buffer. It now only makes one call.
863 - added public constructors for I/O layer objects (see Imager::IO)
865 - all core file handlers now use the i_io_foo() wrappers to gain
866 access to buffered I/O rather than calling the I/O layer
869 - all core file handlers now check for error on close.
871 - Backward compatibility: if you hava custom file handlers, you can
872 use i_io_write() etc since they're available as macros in older
875 - eliminate the final remnants of io_glue_commit_types().
877 - bump IMAGER_API_VERSION, since the above may break assumptions.
879 - removed the long unused i_gen_reader() and i_gen_writer() utility
882 Imager 0.85 - 29 Aug 2011
885 The main changes in the release versus 0.84 are:
887 - on 64-bit systems, 64-bit types are consistently used for image
888 dimensions and co-ordinated, and for memory block sizes.
890 - handle IFD loops in TIFF files correctly. Previously this would
891 lead to an infinite loop.
895 - fix the link in the getheight() entry in the method index
897 Imager 0.84_02 - 22 Aug 2011
900 Development release, this will become 0.85 if CPAN testers is
905 - the image file limits set by set_file_limits() weren't being
906 checked when reading TIFF files.
907 https://rt.cpan.org/Ticket/Display.html?id=69915
909 - Provide more information about file format module load errors on a
910 failed image file read() or write().
911 https://rt.cpan.org/Ticket/Display.html?id=69194
913 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
914 through TIFF images, since it checks for IFD loops.
915 https://rt.cpan.org/Ticket/Display.html?id=69914
917 - don't leak memory when out of range palette indexes are supplied to
919 https://rt.cpan.org/Ticket/Display.html?id=69242
921 - require a later version of CPAN::Meta to ensure JSON::PP and
922 CPAN::Meta::YAML are available.
923 https://rt.cpan.org/Ticket/Display.html?id=69008
925 - hoist the per-line calculations for the flines implementations, and
926 modernize the tests a bit.
927 https://rt.cpan.org/Ticket/Display.html?id=70126
929 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
931 https://rt.cpan.org/Ticket/Display.html?id=69147
933 - if t1lib failed to reinitialize it would be left as marked
935 https://rt.cpan.org/Ticket/Display.html?id=69877
937 - update the bundled (and still modified) Devel::CheckLib
938 https://rt.cpan.org/Ticket/Display.html?id=69170
940 Imager 0.84_01 - 8 Aug 2011
943 Development release as a sanity check for the types re-work.
945 Massive types re-work:
947 - the type used internally for pixel co-ordinates and image sizes is
948 now 64-bit on 64-bit platforms (at least sane ones).
950 - size_t is now used consistently for memory block sizes.
952 - since this changes the binary interface, the Imager API version has
953 been incremented. Any module that uses the API will need to be
954 rebuilt. In most cases that will be enough, but calls to any APIs
955 that take a pointer to image sizes may need source changes.
957 - you should be able to create very large images on 64-bit systems,
958 if you have enough memory. Successfully created a 32768 x 49192 x
959 3 channel image, filled with a tiled image and scaled it. The
960 unscaled image was also successfully saved to a JPEG.
962 - check the image size before attempting to write BMP, GIF, JPEG,
963 PNG, SGI, TGA, TIFF images.
965 - correctly handle reading TGA images over 32767 pixels wide or tall.
969 - the gif_left and gif_top tags are now clamped to non-negative
970 values when writing a GIF image.
972 - removed dead callback read/write code
974 The default maximum memory size when reading files is now 1G.
976 Imager 0.84 - 20 Jun 2011
979 - Imager no longer inherits from Exporter (unless you're running an
982 - Imager can now write progressive JPEGs (it could always read them).
983 https://rt.cpan.org/Ticket/Display.html?id=68691
987 - re-work, document and test Imager's logging facility.
988 https://rt.cpan.org/Ticket/Display.html?id=65227
990 - fix META.yml testing and the generated META.yml
991 https://rt.cpan.org/Ticket/Display.html?id=65235
993 - test and add error reporting to to_*() family methods
995 - add to_rgb_double() method.
996 https://rt.cpan.org/Ticket/Display.html?id=65101
998 - Imager no longer exports anything by default
999 https://rt.cpan.org/Ticket/Display.html?id=65228
1001 - convert colors to grayscale if the supplied (or generated) palette
1002 contains only grays when performing error diffusion color
1004 https://rt.cpan.org/Ticket/Display.html?id=68508
1006 - writing a paletted image to GIF wouldn't always use the colors
1007 supplied (or generated, eg. via make_colors => "mono"), which was
1009 https://rt.cpan.org/Ticket/Display.html?id=67912
1011 - replace (imager|tony)@imager.perl.org in the doc, since I don't
1012 plan to continue receiving mail at that address.
1013 https://rt.cpan.org/Ticket/Display.html?id=68591
1015 Imager 0.83 - 21 May 2011
1020 - diag() the error message on failure for some TIFF tests that are
1021 failing on a Solaris smoker.
1022 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
1024 Imager 0.82_01 - 17 May 2011
1027 Dev release, in case the compose tests are too sensitive.
1031 - Imager::Font::T1 incorrectly checked for absolute filename under
1032 Win32. Thanks to kmx for the report and fix.
1033 https://rt.cpan.org/Ticket/Display.html?id=67963
1035 - compose() with the target, source or mask position off the top or
1036 left of the target image didn't clip the source image correctly.
1037 https://rt.cpan.org/Ticket/Display.html?id=67220
1039 - compose() now returns a useful error message on a non-positive
1042 - compose.im now at 100% test coverage. (As opposed to, umm, much,
1045 Imager 0.82 - 14 Mar 2011
1050 - eliminate calls to i_has_format() from the test suite, since it's
1051 no longer a useful way to check for file format support. Eliminate
1052 i_has_format() from the functions exposed via XS.
1053 https://rt.cpan.org/Ticket/Display.html?id=65863
1055 - eliminate calls to note(), which isn't in the (very old) version of
1056 Test::More we have as a pre-requisite. note() is modern enough
1057 that I don't feel a need to require a Test::More upgrade for it.
1058 https://rt.cpan.org/Ticket/Display.html?id=65864
1060 - skip the threads tests on Test::More 2.00_*
1061 https://rt.cpan.org/Ticket/Display.html?id=65812
1063 - add an (unshipped) test to check Imager's internal POD links
1064 https://rt.cpan.org/Ticket/Display.html?id=65749
1066 - improve the library detection summary
1067 https://rt.cpan.org/Ticket/Display.html?id=9675
1069 - increase the version of Imager::Font::Type1 so that upgrades don't
1070 downgrade the version in this file.
1071 https://rt.cpan.org/Ticket/Display.html?id=66250
1073 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
1074 that option for the directories that would normally go in
1075 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
1076 https://rt.cpan.org/Ticket/Display.html?id=65955
1078 Imager 0.81 - 14 Feb 2011
1081 - added coverage tests for masked images (maskimg.c @100% test coverage)
1083 - add hsv() method to Imager::Color
1084 Thanks to Leolo (Philip Gwyn)
1085 https://rt.cpan.org/Ticket/Display.html?id=65385
1087 - split libt1 Type 1 font support into a sub-module
1088 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1090 - add a preload() class method for use in forking servers, and to
1091 work around limitations in PAR.
1092 https://rt.cpan.org/Ticket/Display.html?id=65665
1096 - paletted writes to a masked image are now masked correctly.
1097 Revealed by new coverage tests.
1099 - update the filter plugin documentation.
1100 https://rt.cpan.org/Ticket/Display.html?id=56513
1102 - add the matrix() method to Imager::Matrix2d to allow creation of a
1103 matrix with specified co-efficients. You can now multiple an
1104 Imager::Matrix2d object by a 9 element array ref or a number.
1105 https://rt.cpan.org/Ticket/Display.html?id=29938
1107 - really fix loading TTF fonts with FT2 when FT1 isn't available.
1108 Thanks to Leolo (Philip Gwyn)
1109 https://rt.cpan.org/Ticket/Display.html?id=65386
1110 https://rt.cpan.org/Ticket/Display.html?id=62855
1112 - make sure each test script that needs testout/ creates it.
1113 https://rt.cpan.org/Ticket/Display.html?id=65088
1115 - handle a slightly different warning from libtiff 4.x
1116 https://rt.cpan.org/Ticket/Display.html?id=65268
1118 - the sat transform2() op returned an incorrect saturation.
1119 https://rt.cpan.org/Ticket/Display.html?id=65391
1121 Imager 0.80 - 17 Jan 2011
1124 - added coverage tests for Imager::Fountain and Imager::Color::Float
1126 - Imager is now maintained in git
1127 http://git.imager.perl.org/imager.git
1128 git://git.imager.perl.org/imager.git
1132 - images with an translucent alpha channel were not scaled correctly
1133 by the default (qtype=normal) scaling method.
1134 https://rt.cpan.org/Public/Bug/Display.html?id=63922
1136 - Imager::Color::Float now translates "#FFFFFF" to white instead of
1137 just a little darker.
1139 - make the default color map build algorithm "mediancut". This
1140 changes the default color map builder for writing GIFs back to what
1141 it was in 0.77, reverting a performance regression.
1142 https://rt.cpan.org/Ticket/Display.html?id=64785
1144 - handle failure to create a masked image correctly
1146 Imager 0.79 - 10 Dec 2010
1149 - add Imager::Test to the POD coverage tests and document the missing
1152 - the convert() method now optimizes the case where all output
1153 channels are either 0, sourced from a single input channel or 1.
1154 This significantly speeds up presets like "addalpha", "green".
1155 https://rt.cpan.org/Ticket/Display.html?id=51254
1157 - add wiggle.pl sample, as suggested by Dan Oppenheim.
1159 - add the combine() method to combine channels from multiple source
1160 images into a new image
1161 https://rt.cpan.org/Ticket/Display.html?id=11872
1165 - treat the co-efficients for convert() as doubles instead of floats.
1167 - If a higher (earlier) priority font handler failed to load, that
1168 would crash preventing loading of later font handlers.
1169 https://rt.cpan.org/Ticket/Display.html?id=62855
1171 - parse defines from the options returned by pkg-config --cflags
1172 https://rt.cpan.org/Ticket/Display.html?id=63223
1174 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
1175 included in the tarball. They are now included.
1177 Imager 0.78 - 4 Oct 2010
1182 - don't access deprecated members of the png_structp.
1183 https://rt.cpan.org/Ticket/Display.html?id=60242
1185 - document that using color objects is faster than supplying colors
1187 https://rt.cpan.org/Ticket/Display.html?id=61047
1189 - Imager::Probe now accepts array references for incpath and libpath.
1190 https://rt.cpan.org/Ticket/Display.html?id=60244
1192 Imager 0.77_02 - 27 Sep 2010
1195 - moved Win32, FreeType 2 font support into sub-modules.
1196 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1197 Uses Imager::Probe now.
1198 https://rt.cpan.org/Public/Bug/Display.html?id=61328
1200 - tested successfully with jpeg-8b
1201 https://rt.cpan.org/Ticket/Display.html?id=60221
1205 - from _01: look for missing file support test files in the right
1208 - flood_fill() wouldn't fill the right side of a single scan-line
1210 Thanks to Nicolas Roggli for reporting this.
1212 - flood_fill wouldn't fill to the left edge of the image if the
1213 starting line didn't reach the left edge.
1214 Thanks to Nicolas Roggli for reporting this.
1216 Imager 0.77_01 - 13 Sep 2010
1219 - add each library-directory/pkgconfig/ to the pkg-config search path
1221 Thanks to Justin Davis.
1222 https://rt.cpan.org/Ticket/Display.html?id=60491
1224 - moved GIF, TIFF, JPEG file handling code into sub-modules in
1225 preparation for separate distribution.
1226 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1228 Note: this removed support for libungif from Imager.
1230 - optimize filled box drawing (color, not fill)
1234 - Imager::Probe was calling ExtUtils::Liblist to initialize
1235 LD_RUN_PATH supplying an undefined value rather than the found
1236 directory. Thanks to Justin Davis.
1237 https://rt.cpan.org/Ticket/Display.html?id=60491
1239 - only prepend ./ to font filenames when passing them to T1Lib and
1240 then only when it would use its search mechanisms.
1241 https://rt.cpan.org/Ticket/Display.html?id=60509
1243 - fix the cache check for the X rgb.txt loader. This is typically
1244 used for color translation on Unix-like systems, and the fix
1245 improves performance of supplying colors by name by about 80 times.
1246 Test code that managed 3400 10x10 pixel boxes/second sped up to
1249 - clarify that Imager doesn't write EXIF metadata to images.
1250 https://rt.cpan.org/Ticket/Display.html?id=60637
1252 - Imager::Probe can now search subdirectories under its include path.
1253 Used by the PNG Makefile.PL to find headers and libraries when they
1254 aren't in the base directory, as in cygwin.

1257 Imager 0.77 - 11 Aug 2010
1260 I don't want Imager::File::PNG indexed as part of Imager, but forgot
1261 to update the META.yml before updating the version.
1263 - don't index Imager::File::PNG as part of Imager
1265 - add resources to META.yml
1267 Imager 0.76 - not released
1272 - the align_string() method would ignore a string of "0" due to a
1273 mis-use of C< ||= >.
1274 Thanks to Maurice Height for reporting this.
1275 https://rt.cpan.org/Ticket/Display.html?id=60199
1277 Imager 0.75_03 - 09 Aug 2010
1282 - read_types() and write_types() would include png when it wasn't
1283 available due to a problem with the %formats tie
1285 - handle dependent libraries correctly (eg -lpng requiring -lz) in
1286 the code run phase of library probing.
1288 Imager 0.75_02 - 07 Aug 2010
1293 - add file missing from MANIFEST, which was causing TIFF failures.
1295 Imager 0.75_01 - 06 Aug 2010
1298 Test release for the new PNG probe.
1300 - added the ability to read multiple-image PNM files.
1301 Note that unlike the pbm/pgm/ppm specification this accepts mixed
1302 format files and allows white space padding between files.
1303 Thanks to Philip Gwyn (Leolo) for this patch.
1305 - moved the PNG file handling code into a sub-module in preparation
1306 for separate distribution.
1307 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1308 Also helps avoid complications from -I/-L compile/link options from
1313 - Imager->new(data => $data) didn't try to process image file data in
1315 https://rt.cpan.org/Ticket/Display.html?id=58761
1317 - t/t50basicoo.t no longer depends on the other tests to generate its
1319 https://rt.cpan.org/Ticket/Display.html?id=9798
1320 Also, it wasn't testing pnm (pnm vs ppm mix-up)
1322 - update the documentation of hardinvert to match the change in 0.62.
1323 https://rt.cpan.org/Ticket/Display.html?id=59785
1325 - added hardinvertall filter which also inverts the alpha channel
1326 (sorry for the mess)
1328 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
1329 the probe can find the library for the test run.
1330 https://rt.cpan.org/Ticket/Display.html?id=57518
1332 Imager 0.75 - 20 Jun 2010
1335 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
1336 perls (not measured)
1340 - an opacity fill based on a fountain fill would segfault when
1341 filling an 8-bit/sample image.
1343 - merge thickline branch polygon fix
1344 https://rt.cpan.org/Ticket/Display.html?id=43518
1346 Imager 0.74 - 7 May 2010
1351 - read_multi() didn't handle a missing file format library correctly,
1352 aborting on failing to call i_readgif_multi_wiol() or
1353 i_readtiff_multi_wiol().
1355 - fix spelling errors patched by Debian
1356 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
1358 - add an (unshipped) author test to spellcheck Imager's POD.
1360 - update the TIFF file format documentation
1361 https://rt.cpan.org/Ticket/Display.html?id=56510
1363 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
1365 Imager 0.73 - 15 Mar 2010
1368 - implement outline circles, both anti-aliased and not
1369 https://rt.cpan.org/Ticket/Display.html?id=19755
1371 - a combine => "none" fill to a 1 or 3 channel image would produce
1372 the incorrect colour.
1374 Imager 0.72 - 09 Dec 2009
1377 Bump version for release, since 0.71_03 is stable with CPAN testers.
1379 Imager 0.71_03 - 5 Dec 2009
1382 - further adjust the threads test so it only performs the tests on
1383 perls where it's expected to work, and only if the threads module
1386 Imager 0.71_02 - 1 Dec 2009
1389 - adjust the way we load the threads module for the threads test so
1390 it works with non-threaded perls
1392 Imager 0.71_01 - 30 Nov 2009
1397 - use scanline oriented operations to flip images instead of pixel
1399 https://rt.cpan.org/Ticket/Display.html?id=39278
1401 - use double/sample operations to flip large sample images instead of
1402 8-bit sample operations.
1403 https://rt.cpan.org/Ticket/Display.html?id=39280
1406 https://rt.cpan.org/Ticket/Display.html?id=51874
1408 - prevent double-frees when someone creates Imager objects and then
1409 creates a thread. Note: this just handles some simple cases,
1410 Imager doesn't support perl threads, and isn't likely to.
1411 https://rt.cpan.org/Ticket/Display.html?id=52268
1413 Imager 0.71 - 16 Nov 2009
1416 - add the opacity fill type - an adaptor that modifies the opacity of
1421 - the conv filter now enforces that the sum of the coefficients is
1422 non-zero. Also, rather than skipping pixels off the edge off the
1423 edge of the image, the closest edge pixel is used. Previously
1424 dividing by the zero sum of coefficients could cause invalid
1425 results or runtime exceptions.
1426 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
1429 Imager 0.70 - 21 Sep 2009
1434 - release image row and comments memory on all error returns in gif
1437 - handle zero length extensions, previously this would cause a null
1439 Thanks to Krzysztof Wojtaś for the test data and fix for this.
1441 - an integer division meant that preview scaling to below 1 pixel
1442 wide or high (which isn't too useful anyway) was calculating using
1443 NaNs on most platforms, and causing an exception on others.
1444 Thanks to David Cantrell for producing a backtrace of the crash on
1445 his Alpha-NetBSD CPAN test box which made it possible to track this
1448 Imager 0.69 - 08 Sep 2009
1453 - broken test fix - was attempting to call a function skip_all, when
1454 that should be a parameter to plan().
1456 - briefly document apidocs.perl, the tool used to build
1457 Imager::APIRef and make some minor enhancements
1459 - various minor documentation enhancements and fixes.
1461 Imager 0.68 - 07 Sep 2009
1464 - Imager->new(file => $filename) and other similar incantations will
1465 load the given file.
1466 https://rt.cpan.org/Ticket/Display.html?id=48261
1470 - avoid using CHECK as a label in Imager::Test
1471 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
1473 - re-work most image file test files that require a library into
1474 separate library present/not present files to remove stupidly long
1477 - don't treat rubthrough() outside the bounds of the target image as
1479 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
1481 Imager 0.67_01 - 02 Sep 2009
1486 - correct documentation of default of raw image interleave read
1488 https://rt.cpan.org/Ticket/Display.html?id=42074
1490 - add raw_ prefix to raw read parameters, though the original names
1493 - fail the read if an invalid raw_interleave parameter is supplied
1495 - warn if no interleave or raw_interleave parameter is supplied,
1496 since the documented default was wrong, and incompatible with the
1499 - for reading raw images, if raw_storechannels > raw_datachannels,
1500 set the extra channels in the image to 0
1502 - when probing for executables like freetype-config, search for .bat
1503 and .cmd on MSWin32, as well as .exe.
1504 https://rt.cpan.org/Ticket/Display.html?id=49275
1506 - re-work the external libraries section of README:
1507 - list Debian and Redhat package names for each library
1511 - use the new EU::MM META_MERGE facility instead of generating
1512 META.yml from scratch
1513 https://rt.cpan.org/Ticket/Display.html?id=47888
1515 - use Devel::CheckLib (bundled, modified) to check which release of
1516 libtiff is installed and reject 3.9.0
1517 http://bugzilla.maptools.org/show_bug.cgi?id=2088
1518 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
1520 Imager 0.67 - 12 Dec 2008
1525 - fix a packaging error
1527 Imager 0.66 - 12 Dec 2008
1530 - 24-bit color .ICO/.CUR files can now be read.
1534 - an optimization skipping 0 src alpha values could cause the
1535 rubthrough() to read past the end of a buffer.
1536 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
1538 - corrected a reference leak where writing GIFs would leak memory.
1539 This could also happen calling to_paletted().
1540 Also documented the underlying long existing feature where the
1541 colors parameter is filled with the generated color table and added
1543 http://rt.cpan.org/Ticket/Display.html?id=41028
1545 - write out the image size in bytes field of a BMP correctly.
1546 http://rt.cpan.org/Ticket/Display.html?id=41406
1548 - add limited tests for Imager::ExtUtils
1550 - make Imager::ExtUtils->includes use an absolute path, since
1551 a relative path could cause failures using Inline::C.
1552 http://rt.cpan.org/Ticket/Display.html?id=37353
1554 - re-arrange the POD for Imager::Font::BBox:
1555 - mark total_width(), pos_width(), end_offset() obsolete, since
1556 they're mostly for backwards compatibility
1557 - group width methods and height methods
1558 https://rt.cpan.org/Ticket/Display.html?id=39999
1560 Imager 0.65 - 20 May 2008
1565 - In some cases when an error occurs reading those parts of a JPEG
1566 file after the image the scan-line buffer could be freed a second
1567 time. In cases where the the error occured while reading the image
1568 data it's possible that the buffer could have leaked.
1569 Thanks to Gabriel Vasseur for reporting this and help in tracking
1572 - the gif_screen_height tag was overriding the screen width and being
1573 ignored for the screen height when present.
1574 https://rt.cpan.org/Public/Bug/Display.html?id=35568
1576 Imager 0.64 - 23 April 2008
1579 This is a bug fix release. This includes a fix for a possible
1584 - Possible security issue: The floating point sample path for image
1585 based fills had a buffer overflow. This would overwrite the end of
1586 a malloc()ed buffer with double precision floats.
1587 http://rt.cpan.org/Ticket/Display.html?id=35324
1590 - check that the result of fileno($fh) is defined rather than simply
1591 true when read() or write() is supplied with an fh parameter.
1592 http://rt.cpan.org/Ticket/Display.html?id=35139
1594 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1595 resulting in a SIGSEGV when attempting to scale an image to a size
1596 too large to fit in memory. This is a NULL pointer access issue,
1597 not a buffer overflow.
1598 Added a check for the failure.
1599 scale_calculate() (and hence scale()) will now fail if any of the
1600 scale size parameters are a reference.
1601 http://rt.cpan.org/Ticket/Display.html?id=35172
1603 - Regression: filling a greyscale image with a hatch used the wrong
1604 color channels from the supplied fg/bg colors.
1605 https://rt.cpan.org/Ticket/Display.html?id=35278
1607 - fixed a related problem for image fills.
1609 Imager 0.63 - 7 April 2008
1612 This release primarily contains changes to improve ease of use -
1613 rather than you having to convert images to the appropriate number of
1614 channels, Imager handles it internally. How to handle drawing colors
1615 and the default combine mode is a thornier problem left for some other
1618 - the font libraries are now only initialized when needed.
1619 http://rt.cpan.org/Ticket/Display.html?id=28825
1621 - moved the imtoc.perl code into Imager::Preprocess
1623 - paste() and rubthrough() now adapt the source image data to the
1624 destination, so you can now safely paste/rubthrough from greyscale
1625 images to color images or back, or from alpha channel images to
1626 noalpha channels or back.
1627 https://rt.cpan.org/Ticket/Display.html?id=30908
1629 - rubthrough() now falls back to pasting when the source doesn't have
1630 an alpha channel. This effectively treats the source as having a
1631 max alpha channel, the right thing to do.
1632 http://rt.cpan.org/Ticket/Display.html?id=29944
1634 - re-worked most of the area filling code to use a common set of
1635 functions when filling.
1636 Corrected normal combine mode.
1637 Rewrote most of the combine modes to match the way the SVG draft
1638 defines them with respect to a translucent source and destination.
1639 Added tests for translucent source and destination.
1640 Added tests to check 8-bit/sample and double/sample combines work
1642 https://rt.cpan.org/Ticket/Display.html?id=29879
1644 - writing a 2 or 4 channel image to a JPEG file will now write that
1645 image as if composited against a background, black by default,
1646 overridable with the i_background tag/parameter.
1647 https://rt.cpan.org/Ticket/Display.html?id=29876
1649 - writing a 2 or 4 channel image to a PGM/PPM file will now write
1650 that image as if composited against a background, black by default,
1651 overridable with the i_background tag/parameter.
1652 http://rt.cpan.org/Ticket/Display.html?id=30074
1654 - writing a 2 or 4 channel image to a BMP file will now write that
1655 image as if composited against a background, black by default,
1656 overridable with the i_background tag/parameter.
1657 http://rt.cpan.org/Ticket/Display.html?id=30075
1661 - Imager::Matrix2d->translate() now only requires one of the x or y
1663 http://rt.cpan.org/Ticket/Display.html?id=29937
1665 - mixing qtype scaling now sets all channels of a pixel to zero if
1666 the pixel has zero coverage (zero alpha). This should produce more
1667 compressible output files.
1668 http://rt.cpan.org/Ticket/Display.html?id=32324
1670 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
1672 https://bugzilla.redhat.com/show_bug.cgi?id=166254
1673 I'm not changing the #! lines of the sample code, since it's sample
1674 code, not intended for installation.
1675 http://rt.cpan.org/Ticket/Display.html?id=33408
1677 - some TGA images weren't being detected correctly as TGA images
1678 https://rt.cpan.org/Ticket/Display.html?id=32925
1680 - handling of the left-over bit for 16-bit/pixel TGA images has been
1681 changed to match the behaviour of the GIMP. Previously the bit
1682 being set was treated as an opaque pixel, but one user reported a
1683 problem with loading such an image. I haven't been able to find any
1684 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1685 I'll match it's behaviour. See issue 114913 in the GIMP's
1687 http://rt.cpan.org/Ticket/Display.html?id=32926
1689 Imager 0.62 - 10 December 2007
1692 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
1693 to /path under your home directory.
1694 http://rt.cpan.org/Ticket/Display.html?id=29484
1696 - the old dynaload code used Mach API functions to load dynamic
1697 libraries on Mac OS X. These APIs have been deprecated in OS X
1698 10.5 and were causing some build problems.
1699 So henceforth Imager uses the dlopen() family of functions, and you
1700 will need version 10.3 or later of OS X.
1702 - added the det() function to the transform2() engine.
1703 added the sample quad_to_square.pl
1704 Courtesy Richard Fairhurst.
1705 http://rt.cpan.org/Ticket/Display.html?id=31244
1709 - samples/gifscale.pl sourced the base value for gif_top from
1711 Thanks to Eleneldil G. Arilou for pointing this out.
1713 - t/t82inline.t no longer loads B at runtime, to work around a bug
1714 in some 5.005_0[45] installations.
1715 http://rt.cpan.org/Ticket/Display.html?id=30508
1717 - work around Module::Depends::Intrusive bug #21229
1718 http://rt.cpan.org/Ticket/Display.html?id=30520
1720 - the hardinvert filter no-longer inverts the alpha channel.
1721 http://rt.cpan.org/Ticket/Display.html?id=30002
1723 - the hardinvert filter now supports large samples
1725 Imager 0.61_02 - 28 November 2007
1728 - major TIFF support re-work
1729 http://rt.cpan.org/Ticket/Display.html?id=20329
1731 - added a C level image interface for accessing samples from 1-32
1732 bits, exposed this at the perl level in getsamples()
1734 - the conv filter now works at floating point precision for high bit
1737 - added is_bilevel method to test whether an image should be written as
1738 a bilevel image if the image format supports it.
1740 - added -log-stderr as an Imager import list option
1742 - added some important types to Imager::APIRef
1744 - added test_image_double() to Imager::Test
1748 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
1751 - the scale() method with qtype mixing now handles images with an
1752 alpha channel correctly.
1754 - fixed a broken link from the "animated GIF" entry in the concept index.
1755 Thanks to Slaven Rezic.
1756 http://rt.cpan.org/Ticket/Display.html?id=30889
1758 - on some perl's the infix expression parser test would fail due to
1759 actions in the grammar returning false. Made sure all actions return
1761 Thanks to Richard Fairhurst for spending a lot of time in tracking
1763 http://rt.cpan.org/Public/Bug/Display.html?id=29562
1765 Imager 0.61 - 5 November 2007
1768 - added samples/gifscale.pl, which adjusts the screen size/position tags
1769 when scaling an animated gif
1770 http://rt.cpan.org/Ticket/Display.html?id=27591
1774 - correct handling of sz in matrix_transform() - this should allow
1775 perspective type transformations to work now.
1776 http://rt.cpan.org/Ticket/Display.html?id=29936
1778 - prevent a cast to integer warning on x64 builds in datatypes.c
1779 also fixed some other type warnings
1780 https://rt.cpan.org/Ticket/Display.html?id=30204
1782 - some sub-directory tests depended on files produced by the parent
1784 http://rt.cpan.org/Ticket/Display.html?id=30203
1786 - Imager::Font::Wrap doesn't correctly set savepos
1787 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
1788 http://rt.cpan.org/Ticket/Display.html?id=29771
1790 - test 171 in t/t01introvert.t was failing on perls configured to
1792 http://rt.cpan.org/Ticket/Display.html?id=29413
1794 - the code for the transform2() uminus operator was missing a break.
1795 Added tests for better code coverage of the ops.
1796 http://rt.cpan.org/Ticket/Display.html?id=29296
1798 - the SGI RLE compression code could overflow its compression buffer
1799 http://rt.cpan.org/Ticket/Display.html?id=30334
1801 - the 32-bit output function used by the SGI code only handled values
1802 under 0x10000. This was most noticable when writing large RLE images.
1803 http://rt.cpan.org/Ticket/Display.html?id=30335
1805 - validate chan_count for chans == NULL for each of the i_gsamp()
1807 http://rt.cpan.org/Ticket/Display.html?id=28985
1809 - attempt to work around the test failure at
1810 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
1811 http://rt.cpan.org/Ticket/Display.html?id=29562
1813 - improve the error messages produced when attempting to read or write
1814 an unknown image file format.
1815 http://rt.cpan.org/Ticket/Display.html?id=30103
1817 - improve the transform2() documentation
1818 http://rt.cpan.org/Ticket/Display.html?id=29267
1820 - correctly generate the author key in META.yml
1821 http://rt.cpan.org/Ticket/Display.html?id=30377
1823 - correctly blend a rotated (or matrix_transformed()) image when
1824 performing interpolation in the presence of an alpha channel.
1825 Also corrected the centring of the rotated image on the output
1828 Imager 0.60 - 30 August 2007
1831 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
1832 now has full SGI RGB image format, including RLE and 16-bit/sample
1834 https://rt.cpan.org/Ticket/Display.html?id=8666
1836 - logging functions are now available in the API
1838 - applied Gabriel Vasseur's patch
1839 added documentation, further tests, and support for greyscale images
1840 Obviously problems are my fault :)
1841 https://rt.cpan.org/Ticket/Display.html?id=28142
1843 - the mask for ICO/CUR images is now applied as an alpha channel to
1844 the returned image. For the old behaviour, supply ico_masked => 0
1845 to read() or read_multi(). This should be less confusing when
1846 using Imager as a general image processor.
1847 https://rt.cpan.org/Ticket/Display.html?id=29001
1851 - in some cases it's possible for giflib/libungif to return color
1852 indexes outside the range of colors defined by the image's palette.
1853 We now expand the palette to match the indexes used.
1854 Thanks to Gabriel Vasseur for reporting this.
1856 - fixed various memory leaks that could occur when failing to read png,
1857 jpeg, bmp or tga files.
1859 - to avoid confusion, channels not present in the image are returned as
1860 zero by getscanline(). This has no effect on the C level i_glin()
1861 and i_glinf() API functions which continue to not set the unused
1864 - the convert() method now returns an image of the same sample size as
1866 https://rt.cpan.org/Ticket/Display.html?id=28492
1868 - remove repeated text in Imager::Files
1869 http://rt.cpan.org/Ticket/Display.html?id=27589
1871 - be even more explicit that scale() and friends don't modify the source
1872 image, but return a new image.
1873 http://rt.cpan.org/Ticket/Display.html?id=28570
1875 - improve the error message from errstr() when you try to load a font
1876 for which the driver hasn't been built in Imager.
1877 http://rt.cpan.org/Ticket/Display.html?id=27571

2002 https://rt.cpan.org/Ticket/Display.html?id=24391
2004 Imager 0.55 - 16 Dec 2006
2007 This is primarily a bug fix release.
2009 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2011 There is one new feature:
2013 - the Win32 font driver now supports UTF8 (RT 22166)
2014 http://www.cpanforum.com/threads/3276
2015 http://rt.cpan.org/Ticket/Display.html?id=22166
2017 Several bugs were fixed:
2019 - the string() method would not output the string "0"
2020 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2022 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2023 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2025 - the gif_disposal and gif_user_input tags weren't being read from
2027 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2029 - gif.c was failing to build under MSVC
2030 http://rt.cpan.org/Ticket/Display.html?id=23922
2032 - in some cases strings passed to the string() method were treated as
2033 terminated by NUL (chr 0)
2034 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2036 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2037 that's the default build name for zlib on Win32.
2038 http://rt.cpan.org/Ticket/Display.html?id=23064
2040 - search $Config{incpath} for headers too, which we should have been
2043 Win32 font driver fixes:
2045 - the global descent value from bounding box was the wrong sign
2046 http://www.cpanforum.com/threads/3276
2048 - if the first or last glyph overflowed the left or right side of the
2049 advance width they would be clipped
2052 Imager 0.54 - 14 Sep 2006
2055 This is primarily a feature release:
2057 - a new qtype value 'mixing' has been added to the scale()
2058 method. This is faster than 'normal', slower than 'preview'. This
2059 is based on the method used by pnmscale, and seems to produce less
2060 blurry results than normal.
2061 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2063 - the rubthrough() method can now render onto images with an alpha
2065 http://rt.cpan.org/Ticket/Display.html?id=20678
2067 - the read_multi() method now falls back to calling doing a single
2068 image read via the read() method and write_multi() will now fall
2069 back to calling write() if a single image is supplied. This means
2070 you can simply call the read_multi() or write_multi() functions
2071 without having to check if the type is formatted by that method.
2072 http://rt.cpan.org/Ticket/Display.html?id=19457
2073 http://rt.cpan.org/Ticket/Display.html?id=19458
2075 - the GIF loop extension can now be written. If you don't have
2076 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2078 http://rt.cpan.org/Ticket/Display.html?id=21185
2080 - getscanline() and setscanline() can now read/write palette index
2081 based data from/to the image for paletted images, by setting type to
2083 http://rt.cpan.org/Ticket/Display.html?id=20338
2085 - we no longer hassle you to disable GIF support
2086 http://rt.cpan.org/Ticket/Display.html?id=20687

2094 This is a bugfix release.
2096 Some test code was left in a code path not covered by the test
2097 suite. A test was added to cover this code path and the test code was

2102 Imager 0.52 - 25 Jul 2006
2105 This is primarily a feature release, but contains a fair few bug
2106 fixes, new features:
2108 - ability to read and write MS Windows ICO and CUR files
2110 - you can now add file format plugins to support new file formats
2112 - add POD coverage tests
2114 - setcolors() and addcolors() now accept color names and so on
2115 instead of requiring Imager::Color objects.
2116 http://rt.cpan.org/Ticket/Display.html?id=20056
2118 - flood_fill() can now fill to a specified border color instead of
2119 just to the area the same color as the seed.
2120 http://rt.cpan.org/Ticket/Display.html?id=19618
2125 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2126 calculating the advance width.
2127 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2129 - bounding_box for the T1 driver wasn't including leading and
2130 trailing spaces in the bounding box as the other drivers did, it also
2131 produced strange results for empty strings or strings containing only
2134 - when reading CMYK jpeg images they were being transferred to the
2135 image object as is, producing a four channel image. It only looked ok
2136 due to an old still unfixed Photoshop bug. We now convert from the
2137 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2138 http://rt.cpan.org/Ticket/Display.html?id=20416
2140 - reading a CYMK TIFF would result in a 4 channel image, reading any
2141 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2143 http://rt.cpan.org/Ticket/Display.html?id=20415
2145 - added /usr/local/include to the default include search path, since
2146 we were already searching /usr/local/lib for libraries.
2148 And various minor fixes and documentation updates.
2151 Imager 0.51 - 23 Apr 2006

2164 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2167 Imager 0.50 - 29 Mar 2006
2170 - CRITICAL: fixes a segmentation fault from attempting to write a 2
2171 or 4 channel image to jpeg or a 2 channel image to tga where the
2172 output is an in-memeory buffer.
2173 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2175 - fixes an incorrect pointer parameter in the PNG code
2176 http://rt.cpan.org/Public/Bug/Display.html?id=18051
