1 Imager release history. Older releases can be found in Changes.old
3 Coverity finally finished a build, fix a few problems:
5 - reading a color-mapped TGA file with an id string would cause a
6 double-free if the palette was truncated.
8 - mixing scaling to sizes where the accumulator row, the working
9 output row or the working input row didn't fit into the address
10 space could result in memory leaks. This can probably only be
11 reproduced on very wide floating-point sample images.
13 - convert an array style function parameter pointer to pointer style
14 to prevent confusing Coverity in the T1 bounding box implementation.
16 - Similarly in the FT1 bounding box implementation.
18 - initialize a pointer to prevent Coverity complaining in polygon
19 drawing (it should always end up being set.)
21 - addi style makemap could potentially read one past the end of an
24 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
25 would result in read beyond the end of the built-in hatch array.
26 Negative values (which Coverity didn't complain about) could also
29 - the Imager::Color set_internal() interal method no longer
30 calls the over-complicated ICL_set_internal() (which is retained
31 only for the old API.) Coverity complained that this leaked, but
32 this could only occur with an invalid (NULL pointer) color object.
34 - the underlying implementation of the map() method could read before
35 the beginning on an allocated array if supplied with inconsistent
36 parameters, which Coverity complained about. No Imager code calls
37 that function with inconsistent parameters, but a
38 belt-and-suspenders check was added.
40 Imager 1.008 - 31 Dec 2018
43 - moved EXIF handling from Imager::File::JPEG to core Imager
44 This allows file formats that store EXIF data as blobs similarly
45 to JPEG to re-use this code. (such as Imager::File::WEBP)
47 - added some more file extensions to image file type mappings
49 - added add_type_extensions() class method
51 Imager 1.007 - 24 Nov 2018
54 - add png_compression_level tag for writing PNG files.
56 - avoid flooring a second time in matrix transform interpolation.
57 https://rt.cpan.org/Ticket/Display.html?id=124001
59 - produce v2 metadata.
60 Includes change from the ticket and updates to sub-modules.
61 https://rt.cpan.org/Ticket/Display.html?id=127216
63 - improve error reporting for the polygon() method
65 Imager 1.006 - 26 Aug 2017
68 - the internal i_errors() function now correctly allocates the stack
69 space needed for its result.
70 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
72 - t/100-base/020-color.t now uses Imager::Test's test functions
74 https://rt.cpan.org/Ticket/Display.html?id=111993
76 - write_multi() now returns an error result (a false value) if called
77 with a non-(Imager image object). Previously it would typically
79 https://rt.cpan.org/Ticket/Display.html?id=117878
81 - improve the documentation of the jpegquality parameter when
84 - add code to mitigate CVE-2016-1238, Imager will no longer search the
85 default current directory entry in @INC when searching for file
86 format support modules.
88 Imager 1.005 - 16 Apr 2016
91 It's now been ten years since I switched to the new Changes file in
94 - revert the ivdformat probes, they don't work as is and trying to
95 fix them is too much work for now.
97 Imager 1.004_004 - 15 Apr 2016
100 - test that the ivdformat from Config is correct and look for a valid
102 For the strange Win32 failures.
104 - fix a copy and paste error in pod in samples/samp-form.cgi
106 Imager 1.004_003 - 23 Mar 2016
109 - add some extra error reporting to the I/O layers tests, this might
110 help catch a failure seen on Win32.
111 http://cpantesters.org/cpan/report/99781689-6bf5-1014-897a-75cb4eee1325
113 Imager 1.004_002 - 20 Mar 2016
116 - don't use the seek() method on opened() handles in
117 t/200-file/400-basic.t. In older versions of perl such handles are
118 only IO::Handle objects, not IO::File, and don't have a seek()
121 Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
124 - re-work the t/200-file/400-basic.t to correctly handle failures
125 It's custom ok() function didn't have a prototype and didn't use scalar().
126 This caused ok() to use the note instead of the value being tested when
127 the method called returned an empty list. For an example of the problem
128 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
130 - remove some noise from when Imager tried to work with bugs in old
131 versions of giflib. I can't do much about the new bugs.
133 - the new autolevels filter (Imager 0.99) used an integer for the
134 sample scaling factor which caused the top output level to be too
135 low (depending on the scaling required.) It now uses a double.
136 https://rt.cpan.org/Ticket/Display.html?id=111871
138 - the new autolevels filter had off-by-one errors calculating the
139 minimum and maximum luminance from the histogram. This slightly
140 reduced the contrast of the output image.
141 https://rt.cpan.org/Ticket/Display.html?id=111871
143 - the new autolevels filter now uses a lookup table for 8-bit images
144 to avoid a floating point multiply for each sample.
145 https://rt.cpan.org/Ticket/Display.html?id=111871
147 - fixed several memory leaks detected by valgrind:
149 - addcolors() leaked the temporary array of colors supplied to the
152 - make_palette() leaked the temporary image array (not the images
153 themselves) passed to the internal API.
155 - combine()/i_combine() leaked its working row buffers
157 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
158 buffer if there were too many colors
160 - getcolorcount()/i_count_colors() leaked the sample buffer if
161 there were too many colors.
163 - the nearest_color filter (undocumented until I find a use for it)
164 leaked both temporaries passed to the API and internal buffers
166 - the internal process of upgrading a paletted image to a direct
167 color image would leak a context object reference count.
169 - a write failure when writing to a GIF file could leak memory.
171 - failing to write to a 1-bit/pixel ICO image could leak memory.
173 - Imager no longer deliberately leaks the context object from the
174 initial thread. This was done to ensure there was always a context
175 object available, but the code that needed that now handles the
178 - fixed some uninitialized memory usage detected by valgrind:
180 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
181 i_matrix_transform_bg() didn't initialize a working color value
182 if there was zero pixel coverage.
184 - i_ft2_cp() didn't initialize the complete color when producing an
185 intermediate image. This caused uninitialized value usage when
188 Imager 1.004 - 8 Nov 2015
191 - Imager::Color::Table is now pre-loaded by the preload() method.
192 https://rt.cpan.org/Ticket/Display.html?id=104896
194 - fix an assertion triggered under perl 5.23.4.
195 Thanks to A. Sinan Unur for the report and the patch.
197 - Imager->new can now be used to read raw image files.
198 https://rt.cpan.org/Ticket/Display.html?id=106836
199 Thanks to Richard Kelsch for reporting this.
201 - deal with output changes from Pod::Spell
202 https://github.com/perl-pod/Pod-Spell/issues/21
204 Imager 1.003 - 12 May 2015
207 - update 1.002 release notes to include the center change for filled
210 - flood_fill() would escape beyond a 4-connected space under some
212 Added many more flood_fill() tests.
213 https://rt.cpan.org/Ticket/Display.html?id=103786
215 Imager 1.002 - 3 Apr 2015
218 - drawing anti-aliased filled circles is now 10 to 50 times faster
219 depending on the size of the circle.
220 This also changed the center from being the center of the pixel to
221 being the top left of the pixel to match the filled arcs drawn by
223 https://rt.cpan.org/Ticket/Display.html?id=101682
225 - enhancements to polygon filling:
227 - added a mode parameter to control how overlapping regions behave
229 - added a polypolygon() method to fill more than one polygon at a
232 - polygon filling is now exposed through the API.
234 - added colormodel(), alphachannel() and colorchannels() methods.
235 These were added for two reasons:
237 - a future version of Imager may allow the number of channels in
238 an image to not directly represent the color model of an image.
239 eg. a greyscale TIFF image with multiple alpha channels.
241 - a future version of Imager may allow an image to be read without
242 translation, for example a TIFF file that contains measurements
243 from an instrument. Currently Imager transforms the samples into
244 the range 0.0 ... 1.0 which may means the user has to translate
247 An untranslated image would be unusable as image data, so
248 colormodel() would return "unknown" in this case.
250 Similarly a CMYK image might be returned as an "unknown" color
251 model image, if the caller chooses to disable translation to
254 Imager 1.001 - 2 Jan 2015
257 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
258 Thanks to Slaven Rezic for the report and the patch.
259 https://rt.cpan.org/Public/Bug/Display.html?id=98234
261 - GIF: clean-up a test file if the test for the giflib 4.2.0 file
264 - fix Imager::Matrix2d::rotate()'s centre point handling
265 https://rt.cpan.org/Public/Bug/Display.html?id=99959
267 - ICO: don't apply the icon mask to images with an alpha channel by
269 https://rt.cpan.org/Public/Bug/Display.html?id=99507
271 - make verbose probing output more verbose
273 - use Imager::Probe to probe for freetype 1.x
274 https://rt.cpan.org/Ticket/Display.html?id=100502
276 - The --enable and --disable parameters to the top-level Makefile.PL
279 - update the bundled/modified Devel::CheckLib to handle the gcc-4
282 Imager 1.000 - 28 Jul 2014
285 There's nothing special about Imager 1.000, it's just another release.
287 - fix the skip check for the iolayer qr// buffer test
289 - improve error reporting for the iolayer test failing on a small
290 number of Win32 CPAN testers
292 Imager 0.99_02 - 21 Jul 2014
295 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
296 the blue channel in the generated palette, and allow each color
297 component to be in the range 100..255 instead of just 100..254.
298 Thanks to Ralf Neubauer.
299 https://rt.cpan.org/Ticket/Display.html?id=97086
301 - revert "improved the XS for i_io_read() and i_io_raw_read()"
302 This caused problems with older perls and didn't provide much of a
303 performance improvement.
305 - support Inline 0.57 and later.
306 Inline 0.57 changed the "with" interface.
307 https://rt.cpan.org/Ticket/Display.html?id=97108
309 - don't define our own MAXINT macro, it conflicts with windows header
310 files and in a few places it was the wrong value to use anyway.
311 https://rt.cpan.org/Ticket/Display.html?id=96425
313 Imager 0.99_01 - 29 Jun 2014
316 - GIF: add support for giflib 5.1.0, which added error code pointer
317 parameters to EGifCloseFile() and DGifCloseFile().
318 https://rt.cpan.org/Ticket/Display.html?id=96756
320 - GIF: avoid a double-free when do_write() fails.
322 - fix SV type probing to work on perl before 5.12. Broken in 0.99.
323 https://rt.cpan.org/Ticket/Display.html?id=96761
325 - PNG: skip the benign error test before libpng 1.6.0, since the
326 error we're testing didn't exist before 1.6.0.
327 https://rt.cpan.org/Ticket/Display.html?id=94717 (continued)
329 Imager 0.99 - 25 Jun 2014
332 - Imager::IO->new_buffer() (and hence Imager->read()'s data
333 parameter) now accepts a reference to a scalar as well as just a
335 https://rt.cpan.org/Ticket/Display.html?id=92785
337 - Imager::IO->new_buffer() now always makes a copy of the passed in
338 buffer to avoid problems with temporary objects used for the return
340 https://rt.cpan.org/Ticket/Display.html?id=92785
342 - improved the XS for i_io_read() and i_io_raw_read()
343 https://rt.cpan.org/Ticket/Display.html?id=92738
345 - load plugins from absolute paths on Android
346 Thanks to Brian Fraser.
347 https://rt.cpan.org/Ticket/Display.html?id=93272
349 - added the jpeg_optimize parameter for writing JPEG files. This can
350 significantly reduce file sizes, but uses more memory and time.
351 https://rt.cpan.org/Ticket/Display.html?id=94292
353 - the autolevels filter now works on the luminosity of the image
354 rather then working per channel. The old autolevels filter is
355 still available as "autolevels_skew".
356 https://rt.cpan.org/Ticket/Display.html?id=94413
358 - Imager::File::PNG now supports libpng 1.6.10.
359 1.6.10 changed CRC errors from benign errors to normal errors,
360 which broke the test which used CRC errors to check for benign
361 error support. Switched to using a 1-bit grey-scale image with a
362 palette to test for benign errors.
363 https://rt.cpan.org/Ticket/Display.html?id=94717
365 Imager 0.98 - 3 Jan 2014
368 Incompatible changes:
370 - the return value of setpixel() has changed.
372 Previously the return values for undrawable pixels vs caller errors
373 changed depending on whether you used the multiple pixel calling
374 mechanism, or the single pixel mechanism.
378 - for an invalid parameter, such as an unknown colour, or missing
379 parameter, an empty list (or undef in scalar context) is
380 returned, and errstr() is set,
382 - otherwise the number of pixels drawn is returned. If none of
383 the pixels could be drawn (they were all outside the image), "0
384 but true" is returned.
386 https://rt.cpan.org/Ticket/Display.html?id=87650
390 - when drawing on an image with an alpha channel where the source
391 minimum is greater than zero, Imager would read from beyond the end
392 of a malloc() allocated buffer. In rare circumstances this could
393 lead to some of the source image not being written to the target
394 image, or possibly to a segmentation fault.
395 I don't believe this has any security concerns beyond that.
397 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
398 text drawn would be nonsense. This would also read beyond the end
399 of a malloced buffer.
401 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
403 https://rt.cpan.org/Ticket/Display.html?id=88993
405 - Imager::Font::Wrap no longer requires the image parameter.
406 https://rt.cpan.org/Ticket/Display.html?id=87338
408 - a documentation typo fix in Imager::Transformations
409 Thanks to Adrian Yee.
410 https://rt.cpan.org/Ticket/Display.html?id=88598
412 - Image::Probe, Imager's internal module for probing library
413 locations now searches the directories specified by LD_RUN_PATH,
414 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
415 and the corresponing s/\blib$/include/ directories for header
417 https://rt.cpan.org/Ticket/Display.html?id=86428
419 Imager 0.97 - 15 Jul 2013
422 No changes from 0.96_02.
424 Imager 0.96_02 - 8 Jul 2013
427 - PNG: treat a version mismatch between headers and library as a
429 https://rt.cpan.org/Ticket/Display.html?id=86659
431 - PNG: the check for benign error support is more complex than a
432 simple library version check, check for the appropriate macro.
433 Thanks for Slaven Rezic for following up on my CPAN Testers result
435 https://rt.cpan.org/Ticket/Display.html?id=86659
437 - W32: add a missing head1 AUTHORS to the old Win32.pm
438 https://rt.cpan.org/Ticket/Display.html?id=86658
440 Imager 0.96_01 - 1 Jul 2013
443 - TIFF: handle SampleFormat = 2 by translating the signed integer
444 values to unsigned by flipping their sign bits.
446 Handle SampleFormat = 3 where possible.
448 SampleFormat is ignored for paletted images.
450 Mixed SampleFormat are handled incorrectly, since libtiff returns
451 only the first SampleFormat value, and an image with both an alpha
452 channel and SampleFormat = 2 for color channels probably has a
453 different SampleFormat for the alpha channel.
455 https://rt.cpan.org/Ticket/Display.html?id=74540
458 https://rt.cpan.org/Ticket/Display.html?id=69243
460 - Imager::Color's rgba() method now returns its values as integers
461 instead of floating point. (IV instead of NV).
463 - The XS for i_map() and i_matrix_transform() now use the AV *
464 typemap instead of rolling their own.
466 - The XS for DSO_call() now uses the HV * typemap instead of
469 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
470 i_gradgen() now use a new T_AVARRAY typemap that greatly
471 simplifies the XS code.
473 - many other minor XS changes
475 - some XS code formatting
477 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
478 now renders in alpha-combining mode, to match antialiased output.
479 https://rt.cpan.org/Ticket/Display.html?id=73359
481 - add sample code and cookbook notes for drawing a blurred drop-shadow.
483 - add support for libpng 1.6, which changed the defaults for
484 reporting some types of error.
485 https://rt.cpan.org/Ticket/Display.html?id=85746
487 - FT2: use gsamp/psamp() to transfer pixels from the work image to
488 the output image instead of gpix/ppix.
489 https://rt.cpan.org/Ticket/Display.html?id=83478
491 - eliminate various GCC warnings, mostly initialized but otherwise
494 Imager 0.96 - 19 May 2013
497 - rearrange Imager's test files.
498 https://rt.cpan.org/Ticket/Display.html?id=84596
500 - Imager::Probe::_gcc_lib_paths now forces C locale.
501 A sufficiently recent gcc prints localized keys for the search
502 paths, which avoids that localization.
503 https://rt.cpan.org/Ticket/Display.html?id=84963
505 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
506 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
508 https://rt.cpan.org/Ticket/Display.html?id=85262
509 reported by Andreas König
511 - add a test for unclosed POD in C source, and fix the errors it
513 https://rt.cpan.org/Ticket/Display.html?id=74875
515 - fix some spelling errors detected by the newer aspell in Debian
518 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
519 thanks to gregor herrmann <gregoa@debian.org>
520 https://rt.cpan.org/Ticket/Display.html?id=85413
522 - add a test for standard =head1 commands and fix the errors found
524 Imager 0.95 - 19 Apr 2013
527 - handle the SVf_UTF8 flag correctly on magic strings passed to
528 Imager::IO's write() and raw_write() methods.
529 This may misbehave in perl 5.6.x since the UTF8 flag may not be
530 visible in the main SV after SvGETMAGIC().
531 https://rt.cpan.org/Ticket/Display.html?id=83438
533 - document that bounding_box() ignores the transformation matrix
534 supplied to tranform() for fonts.
535 https://rt.cpan.org/Ticket/Display.html?id=84106
537 Imager 0.94_02 - 5 Apr 2013
540 - enable debug logging for the standard font tests
542 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
543 due to a bug in that version of perl.
545 - don't test for read() failing on a write-only handle in 5.8.x and
546 earlier, this was fixed in change 862083f7e4 in perl.
548 - report the version of Inline found during testing (an attempt to
549 diagnose some intermittent failures.)
551 Imager 0.94_01 - 2 Mar 2013
554 - NOTE: possibly backward incompatible:
555 support reading from/writing to perl filehandes that aren't raw
558 This allows Imager's I/O to honour handles with layers such as
559 gzip, scalar file handles or tied file handles.
561 This is backward incompatible in that previous Imager would simply
562 use fileno() to retrieve the fd for the file and call write(2) etc
564 https://rt.cpan.org/Ticket/Display.html?id=78843
566 - moved most of README to lib/Imager/Install.pod which should make it
567 more accessible to the "web" generation, also significantly updated
570 - updated README's for the separately distributed modules to refer to
571 Imager::Install, and that they need -dev versions of packages
572 https://rt.cpan.org/Ticket/Display.html?id=81265
574 - the JPEG test code now reports the compile-time library version
576 - avoid a possible compiler optimization issue on CentOS 5.9 i386 by
577 rearranging (and mildly optimizing) some code.
578 https://rt.cpan.org/Ticket/Display.html?id=83212
580 - fix a POD error in Imager::Fill (detected on new Pod-Simple)
581 https://rt.cpan.org/Ticket/Display.html?id=83434
583 - fix a broken link to Graphics::Magick
584 https://rt.cpan.org/Ticket/Display.html?id=82743
586 - drawing text to a channel with FT2 would draw with random coverage
587 due to an uninitialized alpha channel.
589 - marked the function pointer underlying the mm_log() API with the
590 correct gcc magic and fixed the resulting warnings.
592 - fixed some other compiler warnings
594 - Imager::Font::W32 now properly reports text drawing errors
595 https://rt.cpan.org/Ticket/Display.html?id=70098
597 - handle the SVf_UTF8 flag correctly on magic (eg. overloaded)
598 strings passed as text to draw(), bounding_box(), has_chars(),
599 glyph_names() (where supported) in each of the font drivers.
600 This may misbehave in perl 5.6.x since the UTF8 flag may not be
601 visible in the main SV after SvGETMAGIC().
602 https://rt.cpan.org/Ticket/Display.html?id=83438 (partial)
604 Imager 0.94 - 15 Dec 2012
605 =========================
607 Variations on some of these changes were included in development
610 - improved thread safety
611 - the internal error stack and log file handle are now in a per-thread
613 - JPEG now captures IPTC information in a thread-safe way
614 - avoid globals where possible for warning capture in libtiff
615 - use a mutex to avoid re-entering thread-unsafe giflib
616 - use a mutex to avoid re-entering thread-unsafe tifflib
617 - use a mutex to avoid re-entering thread-unsafe T1Lib
618 - use a library handle per thread for freetype 2.
619 - use an engine handle per thread for freetype 1.x.
620 - originally these changes broke ABI compatibility, this has been
623 - clarify the return value of getpixel();
624 https://rt.cpan.org/Ticket/Display.html?id=81198
626 - fixed a race condition in parallel testing for T1
628 - fixed a bug in handling yoff for untransformed image-based fills
630 - documentation improvements for Imager::Fill
632 - FT2: report the library version while testing.
634 Imager 0.93 - 15 Oct 2012
639 - previously a transparency enabled GIF write (the default) would
640 always use a GIF89a header even if none of the images were
643 - previously the probe step for freetype-config would fail on cygwin
645 - catch an invalid matrix parameter to convert() instead of crashing
646 https://rt.cpan.org/Ticket/Display.html?id=79922
648 - remove the 16-bit/sample limitation from the documentation for
649 setsamples(), it hasn't applied for many releases.
650 https://rt.cpan.org/Ticket/Display.html?id=79989
652 - don't copy setsamples() data parameter, it may be a large scalar
653 https://rt.cpan.org/Ticket/Display.html?id=79990
655 - clean up .dSYM directories generated performing probes on OS X
658 - pass the --verbose command-line option through to Imager::Probe in
659 sub-module's Makefile.PLs
660 https://rt.cpan.org/Ticket/Display.html?id=75878
664 - support for giflib 5.0. (5.0.1 and later)
665 https://rt.cpan.org/Ticket/Display.html?id=79029
666 The giflib API Imager uses doesn't have a mechanism to set the
667 header version in 5.0.0.
669 - update the GIF library probe code to check for the new giflib 5.0.1
670 EGifSetGifVersion() function, and to check for the giflib 4.2.0
671 uninitialized gif89 bug.
672 https://rt.cpan.org/Ticket/Display.html?id=79679
673 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
675 - avoid static variables when capturing IPTC data from JPEG files
677 - match Imager::Font::T1's error message translations to those from
678 later versions of T1Lib.
680 - for libtiff versions that support extended warning handlers (3.8.0
681 or later), use them to avoid some global variables.
683 - note Image::ExifTool for better metadata support.
684 https://rt.cpan.org/Ticket/Display.html?id=79251
686 Imager 0.92 - 14 Aug 2012
689 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
690 correctly for both probing and runtime.
691 https://rt.cpan.org/Ticket/Display.html?id=77672
693 - allow building JPEG/imexif.c on C89 compilers.
695 - allow building GIF/imgif.c on C89 compilers.
697 Imager 0.91 - 4 Jun 2012
702 - The size of rotated images is no longer rounded up so aggressively.
703 Added rounding to the linear interpolation done for rotate() and
704 matrix_transform() for 1 and 3 channel 8-bit images.
705 Adjusted the two tranlate matrices used to build the final rotation
706 matrix to use the distance between the outlier pixels rather than
707 the pixel dimensions (ie. dimension-1).
708 With all of this the output of rotate(degrees => 270) on an 8-bit
709 image exactly matches the output of rotate(right => 270).
710 https://rt.cpan.org/Ticket/Display.html?id=77063
714 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
715 internals, those names only matter for the XS interface.
717 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
718 the API level compiled into a loadable module such as
719 Imager::File::GIF doesn't match that of Imager. Previously it
720 could be difficult to determine exactly which module was failing to
722 https://rt.cpan.org/Ticket/Display.html?id=77173
724 - added Imager->check_file_limits() as an interface to the
725 i_int_check_image_file_limits() API.
727 - Imager->set_file_limits(reset => 1) now resets the limits to the
728 defaults rather than setting them all to unlimited.
730 - wrote a brief security note as Imager::Security
731 https://rt.cpan.org/Ticket/Display.html?id=68910
733 Imager 0.90 - 30 Apr 2012
738 - Imager::Test::is_imaged() attempted to process an "epsilon"
739 parameter but the prototype didn't allow for the extra parameter.
740 Corrected the prototype.
742 - when downconverting samples (eg. from floating point to 8 bit)
743 Imager now rounds the sample value rather than attempting to
744 allocate input values over output values equally. The old
745 behaviour had the probably surprising effect of converting a
746 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
748 This may result in slightly different 8 or 16-bit output images.
750 - BI_BITFIELD BMP images were handled incorrectly, both in
751 incorrectly calculating the space required for the masks and in
752 processing the image data itself.
753 https://rt.cpan.org/Ticket/Display.html?id=76736
755 - some odd width BMP BI_RLE4 images use run lengths that run one off
756 the edge of the image. Imager now allows this, discarding the
759 - odd length RLE4 runs in BMP images were decoded incorrectly.
761 - pkg-config could sometimes return a library that was in a directory
762 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
763 If no -L is included in the pkg-config library information check if
764 EU::MM can find the library, and if not, search our configured
765 directories and insert that into the library flags.
766 https://rt.cpan.org/Ticket/Display.html?id=75869
768 - Imager::Probe can now probe for libraries with dependent libraries,
769 common for static linking, eg. libpng requires libz.
770 https://rt.cpan.org/Ticket/Display.html?id=74043
772 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
774 - added alternative probe configurations that try to link libz, to
775 handle a statically linked libpng.
776 https://rt.cpan.org/Ticket/Display.html?id=74043
778 - if a probe includes testcode, Imager::Probe now checks that code as
779 part of the process of checking each configuration rather than as a
780 post test of the found configuration. This allows alternate
781 configurations to be checked if a matching but non-working
782 configuration is found.
783 https://rt.cpan.org/Ticket/Display.html?id=74043
787 - when reading or writing images via callbacks, the default callbacks
788 now push an error message indicating that a required callback was
789 called but not supplied.
790 https://rt.cpan.org/Ticket/Display.html?id=76782
792 - clarify which callbacks are required for reading and writing TIFF
795 - improve logging for creation of callback I/O layers.
797 - a little more documentation for Imager::Probe.
799 - the i_get_file_background() and i_get_file_backgroundf() APIs now
800 return int to indicate whether the i_background tag was found.
803 - improve error reporting
804 - add png_interlace, png_bits tags
805 - read paletted images as paletted images, including transparency
806 - read 1 bit greyscale images as a type suitable for other file
807 handlers to write as bilevel
808 - read 16 bit/sample PNG as 16-bit/sample Imager images
809 - write "bilevel" paletted images as 1 bit grayscale images
810 - write paletted images as paletted images
811 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
813 - improved metadata support
814 https://rt.cpan.org/Ticket/Display.html?id=29268
816 Imager 0.89 - 18 Mar 2012
821 - getpixel(..., type => "float") and the API i_gpixf() have been
822 broken on paletted images since they were implemented.
823 https://rt.cpan.org/Ticket/Display.html?id=75258
827 - links in the METHOD INDEX now point at the method documentation
828 rather than the heading you can find them under.
829 https://rt.cpan.org/Ticket/Display.html?id=71495
831 - Imager (and the bundled dynamic modules) no longer fallback to
832 using DynaLoader if loading via XSLoader fails.
833 For the bundled modules this could hide useful error messages.
834 https://rt.cpan.org/Ticket/Display.html?id=75560
836 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
837 buffer in the array of allocations, but just stores the filename
838 pointer and line number.
839 https://rt.cpan.org/Ticket/Display.html?id=70388
841 Imager 0.88 - 22 Feb 2012
844 - describe how to build libgif etc on OS X in such a way as to be
845 compatible with a fat binary perl (such as the system perl), in
847 https://rt.cpan.org/Ticket/Display.html?id=73371
849 - update the change notes for 0.77_01 to indicate that libungif
852 - add some other imaging modules to SEE ALSO
853 https://rt.cpan.org/Ticket/Display.html?id=73906
855 - note that the generator of the apparently non-DFSG-free postscript
856 in MMOne.pfb is a Debian package.
858 - setsamples() is now a true complement to getsamples() - it can
859 write 8-bit or floating point samples from a scalar or array
860 reference. This adds i_psamp() and i_psampf() to the C level API.
862 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
863 changed to make better use of the typemap, but these aren't part of
864 the perl level API anyway. There were no changes to the C level
865 interfaces to these functions.
867 - getpixel() and setpixel() now accept a mix of scalar and array
868 references for the x and y parameters, and unequal array lengths is
870 https://rt.cpan.org/Ticket/Display.html?id=73697
874 - correctly calculate the size of a rotated image
875 https://rt.cpan.org/Ticket/Display.html?id=69261
877 - fix incorrect rounding of color values for matrix_transform() and
879 https://rt.cpan.org/Ticket/Display.html?id=69261
881 - Win32 text output is now done in normal combine mode, the alpha
882 component of the color is now significant.
883 https://rt.cpan.org/Ticket/Display.html?id=70014
885 - remove long unused gif case from read()
886 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
888 - the getsamples() target parameter was being treated as a hashref
889 when it's meant to be an array reference.
890 https://rt.cpan.org/Ticket/Display.html?id=74882
892 - getpixel() and setpixel() now returns an empty list when invalid
893 parameters are supplied.
894 Invalid values for type now result in an error for getpixel().
895 https://rt.cpan.org/Ticket/Display.html?id=73697
897 Imager 0.87 - 03 Jan 2012
900 - document the return value of the filter() method.
901 https://rt.cpan.org/Ticket/Display.html?id=72369
903 - document i_gsamp_bits() and i_psamp_bits().
904 https://rt.cpan.org/Ticket/Display.html?id=68815
906 - properly increment the Imager::Matrix2d $VERSION.
908 - actually include the Imager::Test tests in the dist
910 - correctly read and write 256x256 pixel ICO files
911 https://rt.cpan.org/Ticket/Display.html?id=69599
913 - make the error message from read() or read_multi() when they can't
914 identify the file type match reality.
915 https://rt.cpan.org/Ticket/Display.html?id=72475
917 - read() now uses $FORMATGUESS if it can't determine the file type
918 based on the file header, to match read_multi().
920 - re-work and add tests for def_guess_type(). def_guess_type() no
921 longer returns any random file extension as the file type.
923 - add gray4, gray16 and gray as presets for make_colors.
924 https://rt.cpan.org/Ticket/Display.html?id=67911
926 - add make_palette() method that produces a palette from one or more
929 - fix the Imager dependency for the separately distributed font
931 https://rt.cpan.org/Ticket/Display.html?id=72643
933 - fix i_render_color() to properly draw in "normal" mode - ie. when
934 writing to a 1 or 3 channel image the second or fourth channel of
935 the source color was being ignored, it is now significant.
936 https://rt.cpan.org/Ticket/Display.html?id=71564
938 Imager 0.86 - 31 Oct 2011
941 - improve error reporting for W32 tests
943 Imager 0.85_02 - 24 Oct 2011
948 - eliminate unused i_gif_opts type (clean-up)
949 https://rt.cpan.org/Ticket/Display.html?id=69245
951 - fix combine=0 fill color anti-aliasing on the double/sample path
952 https://rt.cpan.org/Ticket/Display.html?id=71309
954 - make default text color non-transparent
955 https://rt.cpan.org/Ticket/Display.html?id=71469
957 - apply the last of the Debian unforwarded spelling fixes
958 https://rt.cpan.org/Ticket/Display.html?id=70656
960 - the log() method used its message parameter as a C level format
962 https://rt.cpan.org/Ticket/Display.html?id=71653
964 - provide our own STRLEN typemap entry for older perls.
965 https://rt.cpan.org/Ticket/Display.html?id=71641
967 - add extra ppport.h configuration to support older perls.
969 - depend on Scalar::Util, since we use it and older perls don't have
972 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
973 to synthesize it from overloaded "".
975 - use T1_StrError() for error messages on modern libt1
976 https://rt.cpan.org/Ticket/Display.html?id=69879
978 - actually load the font rather than just adding it to the catalog on
981 - Imager::Font->new now produces better error messages for the T1
984 - the font has_chars() method now returns perl's true and false
985 values in list context rather than integers, which should be more
987 https://rt.cpan.org/Ticket/Display.html?id=69158
989 - the btm data structure used by the flood_fill code is now
990 initialized more efficiently.
991 https://rt.cpan.org/Ticket/Display.html?id=68994
993 - updated the Thanks list in README
994 https://rt.cpan.org/Ticket/Display.html?id=71607
996 - check there's at least one coefficient for the convolution filter
997 https://rt.cpan.org/Ticket/Display.html?id=68993
999 - make the APIRef synopsis ordering consistent, older versions of
1000 perl could order it differently.
1001 https://rt.cpan.org/Ticket/Display.html?id=71675
1003 - we rely on Config.pm's d_vsnprintf as to whether we use
1004 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
1005 though it only has _ prefixed versions of these. Define our own
1006 prefixed names on Win32.
1007 https://rt.cpan.org/Ticket/Display.html?id=71642
1009 - fix library detection with MSVC
1011 - search a few more library directories, so EU::MM doesn't discard
1012 them. Hopefully fixes:
1013 https://rt.cpan.org/Ticket/Display.html?id=71643
1015 Imager 0.85_01 - 10 Oct 2011
1018 - add simple tests for the Imager::Test test_image generators
1020 - io_glue I/O buffering re-work:
1022 - reorganize io_glue to do it's own buffering by default
1024 - the unbuffered functions are available as i_io_raw_read() (or
1025 raw_read() from perl) etc but are not recommended for typical
1028 - use the new i_io_peekn() when checking for file magic to avoid
1029 seek, allowing Imager to detect the file type and read the file
1030 from an unseekable stream (for formats that don't use random
1033 - added several new I/O layer API functions.
1035 - fix the TGA performance problem, most noticably on Win32
1036 https://rt.cpan.org/Ticket/Display.html?id=70037
1038 - TIFF now uses wrapper functions of the correct types to avoid casts
1039 https://rt.cpan.org/Ticket/Display.html?id=69912
1041 - the callback IO object did its own buffering, controlled by the
1042 maxbuffer parameter supplied to the read() and write() methods.
1043 This buffering has been removed, to avoid redundancy with the
1044 common io_glue buffering. This also avoids a bug in that code
1045 which could rarely pass a zero length to the read callback and
1046 then panic about the result.
1048 - the callback IO object now tests the result of calling the close
1049 callback, which should return true for success.
1051 - the PNM reader did its own buffering. This buffering has been
1052 removed to avoid redundancy with the common io_glue buffering.
1054 - previously the read handlers for fd and callback I/O layers would
1055 call the underlying interface (POSIX read or your supplied callback)
1056 until it filled the buffer. It now only makes one call.
1058 - added public constructors for I/O layer objects (see Imager::IO)
1060 - all core file handlers now use the i_io_foo() wrappers to gain
1061 access to buffered I/O rather than calling the I/O layer
1064 - all core file handlers now check for error on close.
1066 - Backward compatibility: if you hava custom file handlers, you can
1067 use i_io_write() etc since they're available as macros in older
1070 - eliminate the final remnants of io_glue_commit_types().
1072 - bump IMAGER_API_VERSION, since the above may break assumptions.
1074 - removed the long unused i_gen_reader() and i_gen_writer() utility
1077 Imager 0.85 - 29 Aug 2011
1080 The main changes in the release versus 0.84 are:
1082 - on 64-bit systems, 64-bit types are consistently used for image
1083 dimensions and co-ordinated, and for memory block sizes.
1085 - handle IFD loops in TIFF files correctly. Previously this would
1086 lead to an infinite loop.
1090 - fix the link in the getheight() entry in the method index
1092 Imager 0.84_02 - 22 Aug 2011
1095 Development release, this will become 0.85 if CPAN testers is
1100 - the image file limits set by set_file_limits() weren't being
1101 checked when reading TIFF files.
1102 https://rt.cpan.org/Ticket/Display.html?id=69915
1104 - Provide more information about file format module load errors on a
1105 failed image file read() or write().
1106 https://rt.cpan.org/Ticket/Display.html?id=69194
1108 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
1109 through TIFF images, since it checks for IFD loops.
1110 https://rt.cpan.org/Ticket/Display.html?id=69914
1112 - don't leak memory when out of range palette indexes are supplied to
1114 https://rt.cpan.org/Ticket/Display.html?id=69242
1116 - require a later version of CPAN::Meta to ensure JSON::PP and
1117 CPAN::Meta::YAML are available.
1118 https://rt.cpan.org/Ticket/Display.html?id=69008
1120 - hoist the per-line calculations for the flines implementations, and
1121 modernize the tests a bit.
1122 https://rt.cpan.org/Ticket/Display.html?id=70126
1124 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
1125 them when available.
1126 https://rt.cpan.org/Ticket/Display.html?id=69147
1128 - if t1lib failed to reinitialize it would be left as marked
1130 https://rt.cpan.org/Ticket/Display.html?id=69877
1132 - update the bundled (and still modified) Devel::CheckLib
1133 https://rt.cpan.org/Ticket/Display.html?id=69170
1135 Imager 0.84_01 - 8 Aug 2011
1138 Development release as a sanity check for the types re-work.
1140 Massive types re-work:
1142 - the type used internally for pixel co-ordinates and image sizes is
1143 now 64-bit on 64-bit platforms (at least sane ones).
1145 - size_t is now used consistently for memory block sizes.
1147 - since this changes the binary interface, the Imager API version has
1148 been incremented. Any module that uses the API will need to be
1149 rebuilt. In most cases that will be enough, but calls to any APIs
1150 that take a pointer to image sizes may need source changes.
1152 - you should be able to create very large images on 64-bit systems,
1153 if you have enough memory. Successfully created a 32768 x 49192 x
1154 3 channel image, filled with a tiled image and scaled it. The
1155 unscaled image was also successfully saved to a JPEG.
1157 - check the image size before attempting to write BMP, GIF, JPEG,
1158 PNG, SGI, TGA, TIFF images.
1160 - correctly handle reading TGA images over 32767 pixels wide or tall.
1164 - the gif_left and gif_top tags are now clamped to non-negative
1165 values when writing a GIF image.
1167 - removed dead callback read/write code
1169 The default maximum memory size when reading files is now 1G.
1171 Imager 0.84 - 20 Jun 2011
1174 - Imager no longer inherits from Exporter (unless you're running an
1177 - Imager can now write progressive JPEGs (it could always read them).
1178 https://rt.cpan.org/Ticket/Display.html?id=68691
1182 - re-work, document and test Imager's logging facility.
1183 https://rt.cpan.org/Ticket/Display.html?id=65227
1185 - fix META.yml testing and the generated META.yml
1186 https://rt.cpan.org/Ticket/Display.html?id=65235
1188 - test and add error reporting to to_*() family methods
1190 - add to_rgb_double() method.
1191 https://rt.cpan.org/Ticket/Display.html?id=65101
1193 - Imager no longer exports anything by default
1194 https://rt.cpan.org/Ticket/Display.html?id=65228
1196 - convert colors to grayscale if the supplied (or generated) palette
1197 contains only grays when performing error diffusion color
1199 https://rt.cpan.org/Ticket/Display.html?id=68508
1201 - writing a paletted image to GIF wouldn't always use the colors
1202 supplied (or generated, eg. via make_colors => "mono"), which was
1204 https://rt.cpan.org/Ticket/Display.html?id=67912
1206 - replace (imager|tony)@imager.perl.org in the doc, since I don't
1207 plan to continue receiving mail at that address.
1208 https://rt.cpan.org/Ticket/Display.html?id=68591
1210 Imager 0.83 - 21 May 2011
1215 - diag() the error message on failure for some TIFF tests that are
1216 failing on a Solaris smoker.
1217 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
1219 Imager 0.82_01 - 17 May 2011
1222 Dev release, in case the compose tests are too sensitive.
1226 - Imager::Font::T1 incorrectly checked for absolute filename under
1227 Win32. Thanks to kmx for the report and fix.
1228 https://rt.cpan.org/Ticket/Display.html?id=67963
1230 - compose() with the target, source or mask position off the top or
1231 left of the target image didn't clip the source image correctly.
1232 https://rt.cpan.org/Ticket/Display.html?id=67220
1234 - compose() now returns a useful error message on a non-positive
1237 - compose.im now at 100% test coverage. (As opposed to, umm, much,
1240 Imager 0.82 - 14 Mar 2011
1245 - eliminate calls to i_has_format() from the test suite, since it's
1246 no longer a useful way to check for file format support. Eliminate
1247 i_has_format() from the functions exposed via XS.
1248 https://rt.cpan.org/Ticket/Display.html?id=65863
1250 - eliminate calls to note(), which isn't in the (very old) version of
1251 Test::More we have as a pre-requisite. note() is modern enough
1252 that I don't feel a need to require a Test::More upgrade for it.
1253 https://rt.cpan.org/Ticket/Display.html?id=65864
1255 - skip the threads tests on Test::More 2.00_*
1256 https://rt.cpan.org/Ticket/Display.html?id=65812
1258 - add an (unshipped) test to check Imager's internal POD links
1259 https://rt.cpan.org/Ticket/Display.html?id=65749
1261 - improve the library detection summary
1262 https://rt.cpan.org/Ticket/Display.html?id=9675
1264 - increase the version of Imager::Font::Type1 so that upgrades don't
1265 downgrade the version in this file.
1266 https://rt.cpan.org/Ticket/Display.html?id=66250
1268 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
1269 that option for the directories that would normally go in
1270 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
1271 https://rt.cpan.org/Ticket/Display.html?id=65955
1273 Imager 0.81 - 14 Feb 2011
1276 - added coverage tests for masked images (maskimg.c @100% test coverage)
1278 - add hsv() method to Imager::Color
1279 Thanks to Leolo (Philip Gwyn)
1280 https://rt.cpan.org/Ticket/Display.html?id=65385
1282 - split libt1 Type 1 font support into a sub-module
1283 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1285 - add a preload() class method for use in forking servers, and to
1286 work around limitations in PAR.
1287 https://rt.cpan.org/Ticket/Display.html?id=65665
1291 - paletted writes to a masked image are now masked correctly.
1292 Revealed by new coverage tests.
1294 - update the filter plugin documentation.
1295 https://rt.cpan.org/Ticket/Display.html?id=56513
1297 - add the matrix() method to Imager::Matrix2d to allow creation of a
1298 matrix with specified co-efficients. You can now multiple an
1299 Imager::Matrix2d object by a 9 element array ref or a number.
1300 https://rt.cpan.org/Ticket/Display.html?id=29938
1302 - really fix loading TTF fonts with FT2 when FT1 isn't available.
1303 Thanks to Leolo (Philip Gwyn)
1304 https://rt.cpan.org/Ticket/Display.html?id=65386
1305 https://rt.cpan.org/Ticket/Display.html?id=62855
1307 - make sure each test script that needs testout/ creates it.
1308 https://rt.cpan.org/Ticket/Display.html?id=65088
1310 - handle a slightly different warning from libtiff 4.x
1311 https://rt.cpan.org/Ticket/Display.html?id=65268
1313 - the sat transform2() op returned an incorrect saturation.
1314 https://rt.cpan.org/Ticket/Display.html?id=65391
1316 Imager 0.80 - 17 Jan 2011
1319 - added coverage tests for Imager::Fountain and Imager::Color::Float
1321 - Imager is now maintained in git
1322 http://git.imager.perl.org/imager.git
1323 git://git.imager.perl.org/imager.git
1327 - images with an translucent alpha channel were not scaled correctly
1328 by the default (qtype=normal) scaling method.
1329 https://rt.cpan.org/Public/Bug/Display.html?id=63922
1331 - Imager::Color::Float now translates "#FFFFFF" to white instead of
1332 just a little darker.
1334 - make the default color map build algorithm "mediancut". This
1335 changes the default color map builder for writing GIFs back to what
1336 it was in 0.77, reverting a performance regression.
1337 https://rt.cpan.org/Ticket/Display.html?id=64785
1339 - handle failure to create a masked image correctly
1341 Imager 0.79 - 10 Dec 2010
1344 - add Imager::Test to the POD coverage tests and document the missing
1347 - the convert() method now optimizes the case where all output
1348 channels are either 0, sourced from a single input channel or 1.
1349 This significantly speeds up presets like "addalpha", "green".
1350 https://rt.cpan.org/Ticket/Display.html?id=51254
1352 - add wiggle.pl sample, as suggested by Dan Oppenheim.
1354 - add the combine() method to combine channels from multiple source
1355 images into a new image
1356 https://rt.cpan.org/Ticket/Display.html?id=11872
1360 - treat the co-efficients for convert() as doubles instead of floats.
1362 - If a higher (earlier) priority font handler failed to load, that
1363 would crash preventing loading of later font handlers.
1364 https://rt.cpan.org/Ticket/Display.html?id=62855
1366 - parse defines from the options returned by pkg-config --cflags
1367 https://rt.cpan.org/Ticket/Display.html?id=63223
1369 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
1370 included in the tarball. They are now included.
1372 Imager 0.78 - 4 Oct 2010
1377 - don't access deprecated members of the png_structp.
1378 https://rt.cpan.org/Ticket/Display.html?id=60242
1380 - document that using color objects is faster than supplying colors
1382 https://rt.cpan.org/Ticket/Display.html?id=61047
1384 - Imager::Probe now accepts array references for incpath and libpath.
1385 https://rt.cpan.org/Ticket/Display.html?id=60244
1387 Imager 0.77_02 - 27 Sep 2010
1390 - moved Win32, FreeType 2 font support into sub-modules.
1391 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1392 Uses Imager::Probe now.
1393 https://rt.cpan.org/Public/Bug/Display.html?id=61328
1395 - tested successfully with jpeg-8b
1396 https://rt.cpan.org/Ticket/Display.html?id=60221
1400 - from _01: look for missing file support test files in the right
1403 - flood_fill() wouldn't fill the right side of a single scan-line
1405 Thanks to Nicolas Roggli for reporting this.
1407 - flood_fill wouldn't fill to the left edge of the image if the
1408 starting line didn't reach the left edge.
1409 Thanks to Nicolas Roggli for reporting this.
1411 Imager 0.77_01 - 13 Sep 2010
1414 - add each library-directory/pkgconfig/ to the pkg-config search path
1416 Thanks to Justin Davis.
1417 https://rt.cpan.org/Ticket/Display.html?id=60491
1419 - moved GIF, TIFF, JPEG file handling code into sub-modules in
1420 preparation for separate distribution.
1421 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1423 Note: this removed support for libungif from Imager.
1425 - optimize filled box drawing (color, not fill)
1429 - Imager::Probe was calling ExtUtils::Liblist to initialize
1430 LD_RUN_PATH supplying an undefined value rather than the found
1431 directory. Thanks to Justin Davis.
1432 https://rt.cpan.org/Ticket/Display.html?id=60491
1434 - only prepend ./ to font filenames when passing them to T1Lib and
1435 then only when it would use its search mechanisms.
1436 https://rt.cpan.org/Ticket/Display.html?id=60509
1438 - fix the cache check for the X rgb.txt loader. This is typically
1439 used for color translation on Unix-like systems, and the fix
1440 improves performance of supplying colors by name by about 80 times.
1441 Test code that managed 3400 10x10 pixel boxes/second sped up to
1444 - clarify that Imager doesn't write EXIF metadata to images.
1445 https://rt.cpan.org/Ticket/Display.html?id=60637
1447 - Imager::Probe can now search subdirectories under its include path.
1448 Used by the PNG Makefile.PL to find headers and libraries when they
1449 aren't in the base directory, as in cygwin.
1450 https://rt.cpan.org/Ticket/Display.html?id=60635
1452 Imager 0.77 - 11 Aug 2010
1455 I don't want Imager::File::PNG indexed as part of Imager, but forgot
1456 to update the META.yml before updating the version.
1458 - don't index Imager::File::PNG as part of Imager
1460 - add resources to META.yml
1462 Imager 0.76 - not released
1467 - the align_string() method would ignore a string of "0" due to a
1468 mis-use of C< ||= >.
1469 Thanks to Maurice Height for reporting this.
1470 https://rt.cpan.org/Ticket/Display.html?id=60199
1472 Imager 0.75_03 - 09 Aug 2010
1477 - read_types() and write_types() would include png when it wasn't
1478 available due to a problem with the %formats tie
1480 - handle dependent libraries correctly (eg -lpng requiring -lz) in
1481 the code run phase of library probing.
1483 Imager 0.75_02 - 07 Aug 2010
1488 - add file missing from MANIFEST, which was causing TIFF failures.
1490 Imager 0.75_01 - 06 Aug 2010
1493 Test release for the new PNG probe.
1495 - added the ability to read multiple-image PNM files.
1496 Note that unlike the pbm/pgm/ppm specification this accepts mixed
1497 format files and allows white space padding between files.
1498 Thanks to Philip Gwyn (Leolo) for this patch.
1500 - moved the PNG file handling code into a sub-module in preparation
1501 for separate distribution.
1502 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1503 Also helps avoid complications from -I/-L compile/link options from
1508 - Imager->new(data => $data) didn't try to process image file data in
1510 https://rt.cpan.org/Ticket/Display.html?id=58761
1512 - t/t50basicoo.t no longer depends on the other tests to generate its
1514 https://rt.cpan.org/Ticket/Display.html?id=9798
1515 Also, it wasn't testing pnm (pnm vs ppm mix-up)
1517 - update the documentation of hardinvert to match the change in 0.62.
1518 https://rt.cpan.org/Ticket/Display.html?id=59785
1520 - added hardinvertall filter which also inverts the alpha channel
1521 (sorry for the mess)
1523 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
1524 the probe can find the library for the test run.
1525 https://rt.cpan.org/Ticket/Display.html?id=57518
1527 Imager 0.75 - 20 Jun 2010
1530 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
1531 perls (not measured)
1535 - an opacity fill based on a fountain fill would segfault when
1536 filling an 8-bit/sample image.
1538 - merge thickline branch polygon fix
1539 https://rt.cpan.org/Ticket/Display.html?id=43518
1541 Imager 0.74 - 7 May 2010
1546 - read_multi() didn't handle a missing file format library correctly,
1547 aborting on failing to call i_readgif_multi_wiol() or
1548 i_readtiff_multi_wiol().
1550 - fix spelling errors patched by Debian
1551 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
1553 - add an (unshipped) author test to spellcheck Imager's POD.
1555 - update the TIFF file format documentation
1556 https://rt.cpan.org/Ticket/Display.html?id=56510
1558 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
1560 Imager 0.73 - 15 Mar 2010
1563 - implement outline circles, both anti-aliased and not
1564 https://rt.cpan.org/Ticket/Display.html?id=19755
1566 - a combine => "none" fill to a 1 or 3 channel image would produce
1567 the incorrect colour.
1569 Imager 0.72 - 09 Dec 2009
1572 Bump version for release, since 0.71_03 is stable with CPAN testers.
1574 Imager 0.71_03 - 5 Dec 2009
1577 - further adjust the threads test so it only performs the tests on
1578 perls where it's expected to work, and only if the threads module
1581 Imager 0.71_02 - 1 Dec 2009
1584 - adjust the way we load the threads module for the threads test so
1585 it works with non-threaded perls
1587 Imager 0.71_01 - 30 Nov 2009
1592 - use scanline oriented operations to flip images instead of pixel
1594 https://rt.cpan.org/Ticket/Display.html?id=39278
1596 - use double/sample operations to flip large sample images instead of
1597 8-bit sample operations.
1598 https://rt.cpan.org/Ticket/Display.html?id=39280
1601 https://rt.cpan.org/Ticket/Display.html?id=51874
1603 - prevent double-frees when someone creates Imager objects and then
1604 creates a thread. Note: this just handles some simple cases,
1605 Imager doesn't support perl threads, and isn't likely to.
1606 https://rt.cpan.org/Ticket/Display.html?id=52268
1608 Imager 0.71 - 16 Nov 2009
1611 - add the opacity fill type - an adaptor that modifies the opacity of
1616 - the conv filter now enforces that the sum of the coefficients is
1617 non-zero. Also, rather than skipping pixels off the edge off the
1618 edge of the image, the closest edge pixel is used. Previously
1619 dividing by the zero sum of coefficients could cause invalid
1620 results or runtime exceptions.
1621 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
1624 Imager 0.70 - 21 Sep 2009
1629 - release image row and comments memory on all error returns in gif
1632 - handle zero length extensions, previously this would cause a null
1634 Thanks to Krzysztof Wojtaś for the test data and fix for this.
1636 - an integer division meant that preview scaling to below 1 pixel
1637 wide or high (which isn't too useful anyway) was calculating using
1638 NaNs on most platforms, and causing an exception on others.
1639 Thanks to David Cantrell for producing a backtrace of the crash on
1640 his Alpha-NetBSD CPAN test box which made it possible to track this
1643 Imager 0.69 - 08 Sep 2009
1648 - broken test fix - was attempting to call a function skip_all, when
1649 that should be a parameter to plan().
1651 - briefly document apidocs.perl, the tool used to build
1652 Imager::APIRef and make some minor enhancements
1654 - various minor documentation enhancements and fixes.
1656 Imager 0.68 - 07 Sep 2009
1659 - Imager->new(file => $filename) and other similar incantations will
1660 load the given file.
1661 https://rt.cpan.org/Ticket/Display.html?id=48261
1665 - avoid using CHECK as a label in Imager::Test
1666 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
1668 - re-work most image file test files that require a library into
1669 separate library present/not present files to remove stupidly long
1672 - don't treat rubthrough() outside the bounds of the target image as
1674 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
1676 Imager 0.67_01 - 02 Sep 2009
1681 - correct documentation of default of raw image interleave read
1683 https://rt.cpan.org/Ticket/Display.html?id=42074
1685 - add raw_ prefix to raw read parameters, though the original names
1688 - fail the read if an invalid raw_interleave parameter is supplied
1690 - warn if no interleave or raw_interleave parameter is supplied,
1691 since the documented default was wrong, and incompatible with the
1694 - for reading raw images, if raw_storechannels > raw_datachannels,
1695 set the extra channels in the image to 0
1697 - when probing for executables like freetype-config, search for .bat
1698 and .cmd on MSWin32, as well as .exe.
1699 https://rt.cpan.org/Ticket/Display.html?id=49275
1701 - re-work the external libraries section of README:
1702 - list Debian and Redhat package names for each library
1706 - use the new EU::MM META_MERGE facility instead of generating
1707 META.yml from scratch
1708 https://rt.cpan.org/Ticket/Display.html?id=47888
1710 - use Devel::CheckLib (bundled, modified) to check which release of
1711 libtiff is installed and reject 3.9.0
1712 http://bugzilla.maptools.org/show_bug.cgi?id=2088
1713 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
1715 Imager 0.67 - 12 Dec 2008
1720 - fix a packaging error
1722 Imager 0.66 - 12 Dec 2008
1725 - 24-bit color .ICO/.CUR files can now be read.
1729 - an optimization skipping 0 src alpha values could cause the
1730 rubthrough() to read past the end of a buffer.
1731 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
1733 - corrected a reference leak where writing GIFs would leak memory.
1734 This could also happen calling to_paletted().
1735 Also documented the underlying long existing feature where the
1736 colors parameter is filled with the generated color table and added
1738 http://rt.cpan.org/Ticket/Display.html?id=41028
1740 - write out the image size in bytes field of a BMP correctly.
1741 http://rt.cpan.org/Ticket/Display.html?id=41406
1743 - add limited tests for Imager::ExtUtils
1745 - make Imager::ExtUtils->includes use an absolute path, since
1746 a relative path could cause failures using Inline::C.
1747 http://rt.cpan.org/Ticket/Display.html?id=37353
1749 - re-arrange the POD for Imager::Font::BBox:
1750 - mark total_width(), pos_width(), end_offset() obsolete, since
1751 they're mostly for backwards compatibility
1752 - group width methods and height methods
1753 https://rt.cpan.org/Ticket/Display.html?id=39999
1755 Imager 0.65 - 20 May 2008
1760 - In some cases when an error occurs reading those parts of a JPEG
1761 file after the image the scan-line buffer could be freed a second
1762 time. In cases where the the error occured while reading the image
1763 data it's possible that the buffer could have leaked.
1764 Thanks to Gabriel Vasseur for reporting this and help in tracking
1767 - the gif_screen_height tag was overriding the screen width and being
1768 ignored for the screen height when present.
1769 https://rt.cpan.org/Public/Bug/Display.html?id=35568
1771 Imager 0.64 - 23 April 2008
1774 This is a bug fix release. This includes a fix for a possible
1779 - Possible security issue: The floating point sample path for image
1780 based fills had a buffer overflow. This would overwrite the end of
1781 a malloc()ed buffer with double precision floats.
1782 http://rt.cpan.org/Ticket/Display.html?id=35324
1785 - check that the result of fileno($fh) is defined rather than simply
1786 true when read() or write() is supplied with an fh parameter.
1787 http://rt.cpan.org/Ticket/Display.html?id=35139
1789 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1790 resulting in a SIGSEGV when attempting to scale an image to a size
1791 too large to fit in memory. This is a NULL pointer access issue,
1792 not a buffer overflow.
1793 Added a check for the failure.
1794 scale_calculate() (and hence scale()) will now fail if any of the
1795 scale size parameters are a reference.
1796 http://rt.cpan.org/Ticket/Display.html?id=35172
1798 - Regression: filling a greyscale image with a hatch used the wrong
1799 color channels from the supplied fg/bg colors.
1800 https://rt.cpan.org/Ticket/Display.html?id=35278
1802 - fixed a related problem for image fills.
1804 Imager 0.63 - 7 April 2008
1807 This release primarily contains changes to improve ease of use -
1808 rather than you having to convert images to the appropriate number of
1809 channels, Imager handles it internally. How to handle drawing colors
1810 and the default combine mode is a thornier problem left for some other
1813 - the font libraries are now only initialized when needed.
1814 http://rt.cpan.org/Ticket/Display.html?id=28825
1816 - moved the imtoc.perl code into Imager::Preprocess
1818 - paste() and rubthrough() now adapt the source image data to the
1819 destination, so you can now safely paste/rubthrough from greyscale
1820 images to color images or back, or from alpha channel images to
1821 noalpha channels or back.
1822 https://rt.cpan.org/Ticket/Display.html?id=30908
1824 - rubthrough() now falls back to pasting when the source doesn't have
1825 an alpha channel. This effectively treats the source as having a
1826 max alpha channel, the right thing to do.
1827 http://rt.cpan.org/Ticket/Display.html?id=29944
1829 - re-worked most of the area filling code to use a common set of
1830 functions when filling.
1831 Corrected normal combine mode.
1832 Rewrote most of the combine modes to match the way the SVG draft
1833 defines them with respect to a translucent source and destination.
1834 Added tests for translucent source and destination.
1835 Added tests to check 8-bit/sample and double/sample combines work
1837 https://rt.cpan.org/Ticket/Display.html?id=29879
1839 - writing a 2 or 4 channel image to a JPEG file will now write that
1840 image as if composited against a background, black by default,
1841 overridable with the i_background tag/parameter.
1842 https://rt.cpan.org/Ticket/Display.html?id=29876
1844 - writing a 2 or 4 channel image to a PGM/PPM file will now write
1845 that image as if composited against a background, black by default,
1846 overridable with the i_background tag/parameter.
1847 http://rt.cpan.org/Ticket/Display.html?id=30074
1849 - writing a 2 or 4 channel image to a BMP file will now write that
1850 image as if composited against a background, black by default,
1851 overridable with the i_background tag/parameter.
1852 http://rt.cpan.org/Ticket/Display.html?id=30075
1856 - Imager::Matrix2d->translate() now only requires one of the x or y
1858 http://rt.cpan.org/Ticket/Display.html?id=29937
1860 - mixing qtype scaling now sets all channels of a pixel to zero if
1861 the pixel has zero coverage (zero alpha). This should produce more
1862 compressible output files.
1863 http://rt.cpan.org/Ticket/Display.html?id=32324
1865 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
1867 https://bugzilla.redhat.com/show_bug.cgi?id=166254
1868 I'm not changing the #! lines of the sample code, since it's sample
1869 code, not intended for installation.
1870 http://rt.cpan.org/Ticket/Display.html?id=33408
1872 - some TGA images weren't being detected correctly as TGA images
1873 https://rt.cpan.org/Ticket/Display.html?id=32925
1875 - handling of the left-over bit for 16-bit/pixel TGA images has been
1876 changed to match the behaviour of the GIMP. Previously the bit
1877 being set was treated as an opaque pixel, but one user reported a
1878 problem with loading such an image. I haven't been able to find any
1879 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1880 I'll match it's behaviour. See issue 114913 in the GIMP's
1882 http://rt.cpan.org/Ticket/Display.html?id=32926
1884 Imager 0.62 - 10 December 2007
1887 - Makefile.PL now expands ~/path supplied to --incpath or --libpath

1889 http://rt.cpan.org/Ticket/Display.html?id=29484
1891 - the old dynaload code used Mach API functions to load dynamic
1892 libraries on Mac OS X. These APIs have been deprecated in OS X
1893 10.5 and were causing some build problems.
1894 So henceforth Imager uses the dlopen() family of functions, and you
1895 will need version 10.3 or later of OS X.
1897 - added the det() function to the transform2() engine.
1898 added the sample quad_to_square.pl
1899 Courtesy Richard Fairhurst.
1900 http://rt.cpan.org/Ticket/Display.html?id=31244
1904 - samples/gifscale.pl sourced the base value for gif_top from
1906 Thanks to Eleneldil G. Arilou for pointing this out.
1908 - t/t82inline.t no longer loads B at runtime, to work around a bug
1909 in some 5.005_0[45] installations.
1910 http://rt.cpan.org/Ticket/Display.html?id=30508
1912 - work around Module::Depends::Intrusive bug #21229
1913 http://rt.cpan.org/Ticket/Display.html?id=30520
1915 - the hardinvert filter no-longer inverts the alpha channel.
1916 http://rt.cpan.org/Ticket/Display.html?id=30002
1918 - the hardinvert filter now supports large samples
1920 Imager 0.61_02 - 28 November 2007
1923 - major TIFF support re-work
1924 http://rt.cpan.org/Ticket/Display.html?id=20329
1926 - added a C level image interface for accessing samples from 1-32
1927 bits, exposed this at the perl level in getsamples()
1929 - the conv filter now works at floating point precision for high bit
1932 - added is_bilevel method to test whether an image should be written as
1933 a bilevel image if the image format supports it.
1935 - added -log-stderr as an Imager import list option
1937 - added some important types to Imager::APIRef
1939 - added test_image_double() to Imager::Test
1943 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
1946 - the scale() method with qtype mixing now handles images with an
1947 alpha channel correctly.
1949 - fixed a broken link from the "animated GIF" entry in the concept index.
1950 Thanks to Slaven Rezic.
1951 http://rt.cpan.org/Ticket/Display.html?id=30889
1953 - on some perl's the infix expression parser test would fail due to
1954 actions in the grammar returning false. Made sure all actions return
1956 Thanks to Richard Fairhurst for spending a lot of time in tracking
1958 http://rt.cpan.org/Public/Bug/Display.html?id=29562
1960 Imager 0.61 - 5 November 2007
1963 - added samples/gifscale.pl, which adjusts the screen size/position tags
1964 when scaling an animated gif
1965 http://rt.cpan.org/Ticket/Display.html?id=27591
1969 - correct handling of sz in matrix_transform() - this should allow
1970 perspective type transformations to work now.
1971 http://rt.cpan.org/Ticket/Display.html?id=29936
1973 - prevent a cast to integer warning on x64 builds in datatypes.c
1974 also fixed some other type warnings
1975 https://rt.cpan.org/Ticket/Display.html?id=30204
1977 - some sub-directory tests depended on files produced by the parent
1979 http://rt.cpan.org/Ticket/Display.html?id=30203
1981 - Imager::Font::Wrap doesn't correctly set savepos
1982 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
1983 http://rt.cpan.org/Ticket/Display.html?id=29771
1985 - test 171 in t/t01introvert.t was failing on perls configured to
1987 http://rt.cpan.org/Ticket/Display.html?id=29413
1989 - the code for the transform2() uminus operator was missing a break.
1990 Added tests for better code coverage of the ops.
1991 http://rt.cpan.org/Ticket/Display.html?id=29296
1993 - the SGI RLE compression code could overflow its compression buffer
1994 http://rt.cpan.org/Ticket/Display.html?id=30334
1996 - the 32-bit output function used by the SGI code only handled values
1997 under 0x10000. This was most noticable when writing large RLE images.
1998 http://rt.cpan.org/Ticket/Display.html?id=30335
2000 - validate chan_count for chans == NULL for each of the i_gsamp()
2002 http://rt.cpan.org/Ticket/Display.html?id=28985
2004 - attempt to work around the test failure at
2005 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
2006 http://rt.cpan.org/Ticket/Display.html?id=29562
2008 - improve the error messages produced when attempting to read or write
2009 an unknown image file format.
2010 http://rt.cpan.org/Ticket/Display.html?id=30103
2012 - improve the transform2() documentation
2013 http://rt.cpan.org/Ticket/Display.html?id=29267
2015 - correctly generate the author key in META.yml
2016 http://rt.cpan.org/Ticket/Display.html?id=30377
2018 - correctly blend a rotated (or matrix_transformed()) image when
2019 performing interpolation in the presence of an alpha channel.
2020 Also corrected the centring of the rotated image on the output
2023 Imager 0.60 - 30 August 2007
2026 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
2027 now has full SGI RGB image format, including RLE and 16-bit/sample
2029 https://rt.cpan.org/Ticket/Display.html?id=8666
2031 - logging functions are now available in the API
2033 - applied Gabriel Vasseur's patch
2034 added documentation, further tests, and support for greyscale images
2035 Obviously problems are my fault :)
2036 https://rt.cpan.org/Ticket/Display.html?id=28142
2038 - the mask for ICO/CUR images is now applied as an alpha channel to
2039 the returned image. For the old behaviour, supply ico_masked => 0
2040 to read() or read_multi(). This should be less confusing when
2041 using Imager as a general image processor.
2042 https://rt.cpan.org/Ticket/Display.html?id=29001
2046 - in some cases it's possible for giflib/libungif to return color
2047 indexes outside the range of colors defined by the image's palette.
2048 We now expand the palette to match the indexes used.
2049 Thanks to Gabriel Vasseur for reporting this.
2051 - fixed various memory leaks that could occur when failing to read png,
2052 jpeg, bmp or tga files.
2054 - to avoid confusion, channels not present in the image are returned as
2055 zero by getscanline(). This has no effect on the C level i_glin()
2056 and i_glinf() API functions which continue to not set the unused
2059 - the convert() method now returns an image of the same sample size as
2061 https://rt.cpan.org/Ticket/Display.html?id=28492
2063 - remove repeated text in Imager::Files
2064 http://rt.cpan.org/Ticket/Display.html?id=27589
2066 - be even more explicit that scale() and friends don't modify the source
2067 image, but return a new image.
2068 http://rt.cpan.org/Ticket/Display.html?id=28570
2070 - improve the error message from errstr() when you try to load a font
2071 for which the driver hasn't been built in Imager.
2072 http://rt.cpan.org/Ticket/Display.html?id=27571
2074 - transparency is now enabled by default when writing GIF images
2075 http://rt.cpan.org/Ticket/Display.html?id=27615
2077 - Imager would not load on Windows 98
2078 http://rt.cpan.org/Ticket/Display.html?id=27653
2080 Imager 0.59 - 14 June 2007
2085 - fixes a regression introduced by the fixes for RT 11972
2086 http://rt.cpan.org/Ticket/Display.html?id=27546
2088 - cropping outside the image would return an Imager object with
2089 no low-level image object, instead of returning false.
2090 Fixed by: Philip Gwyn (Leolo)
2091 http://rt.cpan.org/Ticket/Display.html?id=27509
2093 Imager 0.58 - 16 May 2007
2096 No significant changes from 0.57_01.
2098 Imager 0.57_01 - 11 May 2007
2101 - added to_rgb16 to produce a 16-bit/sample version of an image
2103 - improve freetype 1.x text output efficiency
2107 - search another place for rgb.txt, and check all the places
2108 Imager::Color checks when deciding whether to skip testing it
2109 http://rt.cpan.org/Ticket/Display.html?id=26064
2111 - use a convolution kernel size based on the stddev rather than a
2112 fixed size when performing a gaussian blur
2113 http://rt.cpan.org/Ticket/Display.html?id=25645
2115 - document the difference() method's mindist parameter, and debug it.
2117 - put the Imager release number in the Inline::C generated code to
2118 regenerate Inline code when a new release of Imager is installed.
2119 http://rt.cpan.org/Ticket/Display.html?id=26278
2121 - fix rendering on alpha channel images for the FreeType 1.x driver.
2122 http://rt.cpan.org/Ticket/Display.html?id=11972
2124 - fix rendering on alpha channel images for the T1lib driver.
2125 http://rt.cpan.org/Ticket/Display.html?id=11972
2127 - reworked library probing, we can now set more than one probe
2128 function for a library. Disabled the default (non-freetype-config)
2129 library probe and added an extra probe function that searches for
2130 both ft2build.h and whatever it includes, and adds -I as needed.
2131 Hopefully this will fix build problems like
2132 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
2133 http://rt.cpan.org/Ticket/Display.html?id=26086
2135 Imager 0.57 - 30 Apr 2007
2138 This is a maintenence release fixing a security issue in Imager.
2140 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
2141 overflow in malloced memory. There will be further discussion of
2142 this issue in the ticket below.
2143 http://rt.cpan.org/Ticket/Display.html?id=26811
2144 CVE-2007-2459 CVE-2007-2413
2145 The descriptions at cve.mitre.org varied in quality, please see the
2146 ticket at rt.cpan.org for a more accurate description of the issue.
2148 Imager 0.56 - 1 Apr 2007
2151 - added support for reading 16-bit/sample PGM/PPM images
2153 - added support for writing 16-bit/sample PGM/PPM images
2155 - improved performance of reading PBM/PGM/PPM images
2157 - added support for writing PBM images if the image is paletted and
2158 contains only black and white
2160 - added a new make_colors value - "mono"
2162 - switched from the svn log Changes to a manual Changes to reduce
2165 - new sample code - samples/flasher.pl
2169 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
2170 was returning an image object with an extra reference, this
2171 resulted in a memory leak.
2172 http://rt.cpan.org/Ticket/Display.html?id=24992
2174 - fix rendering on alpha channel images for the FreeType 2.x driver
2175 http://rt.cpan.org/Ticket/Display.html?id=11972
2177 - reading bmp files now consitently handles short reads. You can now
2178 supply a parameter to treat a short read as successful and set
2180 http://rt.cpan.org/Ticket/Display.html?id=8426
2182 - previously, reading ASCII PBM files required spaces between samples,
2183 even though the format doesn't require that
2185 - improved documentation of the unsharpmask filter (I hope)
2186 http://rt.cpan.org/Ticket/Display.html?id=25531
2188 - force flushing of the output from i_tt_dump_names() and test output
2189 in t/t35ttfont.t to prevent output from being mixed up.
2190 https://rt.cpan.org/Ticket/Display.html?id=24859
2192 - rewrite a conditional expression as an if() to hopefully work around
2193 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
2194 https://rt.cpan.org/Ticket/Display.html?id=25561
2196 - avoid Data::Dumper in regops.perl to support older releases of perl
2197 https://rt.cpan.org/Ticket/Display.html?id=24391
2199 Imager 0.55 - 16 Dec 2006
2202 This is primarily a bug fix release.
2204 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2206 There is one new feature:
2208 - the Win32 font driver now supports UTF8 (RT 22166)
2209 http://www.cpanforum.com/threads/3276
2210 http://rt.cpan.org/Ticket/Display.html?id=22166
2212 Several bugs were fixed:
2214 - the string() method would not output the string "0"
2215 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2217 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2218 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2220 - the gif_disposal and gif_user_input tags weren't being read from
2222 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2224 - gif.c was failing to build under MSVC
2225 http://rt.cpan.org/Ticket/Display.html?id=23922
2227 - in some cases strings passed to the string() method were treated as
2228 terminated by NUL (chr 0)
2229 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2231 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2232 that's the default build name for zlib on Win32.
2233 http://rt.cpan.org/Ticket/Display.html?id=23064
2235 - search $Config{incpath} for headers too, which we should have been
2238 Win32 font driver fixes:
2240 - the global descent value from bounding box was the wrong sign
2241 http://www.cpanforum.com/threads/3276
2243 - if the first or last glyph overflowed the left or right side of the
2244 advance width they would be clipped
2247 Imager 0.54 - 14 Sep 2006
2250 This is primarily a feature release:
2252 - a new qtype value 'mixing' has been added to the scale()
2253 method. This is faster than 'normal', slower than 'preview'. This
2254 is based on the method used by pnmscale, and seems to produce less
2255 blurry results than normal.
2256 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2258 - the rubthrough() method can now render onto images with an alpha
2260 http://rt.cpan.org/Ticket/Display.html?id=20678
2262 - the read_multi() method now falls back to calling doing a single
2263 image read via the read() method and write_multi() will now fall
2264 back to calling write() if a single image is supplied. This means
2265 you can simply call the read_multi() or write_multi() functions
2266 without having to check if the type is formatted by that method.
2267 http://rt.cpan.org/Ticket/Display.html?id=19457
2268 http://rt.cpan.org/Ticket/Display.html?id=19458
2270 - the GIF loop extension can now be written. If you don't have
2271 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2273 http://rt.cpan.org/Ticket/Display.html?id=21185
2275 - getscanline() and setscanline() can now read/write palette index
2276 based data from/to the image for paletted images, by setting type to
2278 http://rt.cpan.org/Ticket/Display.html?id=20338
2280 - we no longer hassle you to disable GIF support
2281 http://rt.cpan.org/Ticket/Display.html?id=20687
2283 - minor documentation fixes
2286 Imager 0.53 - 26 Jul 2006
2289 This is a bugfix release.
2291 Some test code was left in a code path not covered by the test
2292 suite. A test was added to cover this code path and the test code was
2294 http://rt.cpan.org/Public/Bug/Display.html?id=20705
2297 Imager 0.52 - 25 Jul 2006
2300 This is primarily a feature release, but contains a fair few bug
2301 fixes, new features:
2303 - ability to read and write MS Windows ICO and CUR files
2305 - you can now add file format plugins to support new file formats
2307 - add POD coverage tests
2309 - setcolors() and addcolors() now accept color names and so on
2310 instead of requiring Imager::Color objects.
2311 http://rt.cpan.org/Ticket/Display.html?id=20056
2313 - flood_fill() can now fill to a specified border color instead of
2314 just to the area the same color as the seed.
2315 http://rt.cpan.org/Ticket/Display.html?id=19618
2320 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2321 calculating the advance width.
2322 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2324 - bounding_box for the T1 driver wasn't including leading and
2325 trailing spaces in the bounding box as the other drivers did, it also
2326 produced strange results for empty strings or strings containing only
2329 - when reading CMYK jpeg images they were being transferred to the
2330 image object as is, producing a four channel image. It only looked ok
2331 due to an old still unfixed Photoshop bug. We now convert from the
2332 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2333 http://rt.cpan.org/Ticket/Display.html?id=20416
2335 - reading a CYMK TIFF would result in a 4 channel image, reading any
2336 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2338 http://rt.cpan.org/Ticket/Display.html?id=20415
2340 - added /usr/local/include to the default include search path, since
2341 we were already searching /usr/local/lib for libraries.
2343 And various minor fixes and documentation updates.
2346 Imager 0.51 - 23 Apr 2006
2349 - fix a validation bug when processing JPEG EXIF data that can cause
2351 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2353 - fix mis-processing of the src_maxx and src_maxy parameters of the
2355 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2357 - fix a problem in Imager's "smart" handling of the color parameter
2359 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2362 Imager 0.50 - 29 Mar 2006
2365 - CRITICAL: fixes a segmentation fault from attempting to write a 2
2366 or 4 channel image to jpeg or a 2 channel image to tga where the
2367 output is an in-memeory buffer.
2368 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2370 - fixes an incorrect pointer parameter in the PNG code
2371 http://rt.cpan.org/Public/Bug/Display.html?id=18051
2373 - skip Inline::C tests when building in a directory with spaces
2374 http://rt.cpan.org/Public/Bug/Display.html?id=18049
