1 Imager release history. Older releases can be found in Changes.old
3 Imager 0.99_02 - 21 Jul 2014
6 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
7 the blue channel in the generated palette, and allow each color
8 component to be in the range 100..255 instead of just 100..254.
9 Thanks to Ralf Neubauer.
10 https://rt.cpan.org/Ticket/Display.html?id=97086
12 - revert "improved the XS for i_io_read() and i_io_raw_read()"
13 This caused problems with older perls and didn't provide much of a
14 performance improvement.
16 - support Inline 0.57 and later.
17 Inline 0.57 changed the "with" interface.
18 https://rt.cpan.org/Ticket/Display.html?id=97108
20 - don't define our own MAXINT macro, it conflicts with windows header
21 files and in a few places it was the wrong value to use anyway.
22 https://rt.cpan.org/Ticket/Display.html?id=96425
24 Imager 0.99_01 - 29 Jun 2014
27 - GIF: add support for giflib 5.1.0, which added error code pointer
28 parameters to EGifCloseFile() and DGifCloseFile().
29 https://rt.cpan.org/Ticket/Display.html?id=96756
31 - GIF: avoid a double-free when do_write() fails.
33 - fix SV type probing to work on perl before 5.12. Broken in 0.99.
34 https://rt.cpan.org/Ticket/Display.html?id=96761
36 - PNG: skip the benign error test before libpng 1.6.0, since the
37 error we're testing didn't exist before 1.6.0.
38 https://rt.cpan.org/Ticket/Display.html?id=94717 (continued)
40 Imager 0.99 - 25 Jun 2014
43 - Imager::IO->new_buffer() (and hence Imager->read()'s data
44 parameter) now accepts a reference to a scalar as well as just a
46 https://rt.cpan.org/Ticket/Display.html?id=92785
48 - Imager::IO->new_buffer() now always makes a copy of the passed in
49 buffer to avoid problems with temporary objects used for the return
51 https://rt.cpan.org/Ticket/Display.html?id=92785
53 - improved the XS for i_io_read() and i_io_raw_read()
54 https://rt.cpan.org/Ticket/Display.html?id=92738
56 - load plugins from absolute paths on Android
57 Thanks to Brian Fraser.
58 https://rt.cpan.org/Ticket/Display.html?id=93272
60 - added the jpeg_optimize parameter for writing JPEG files. This can
61 significantly reduce file sizes, but uses more memory and time.
62 https://rt.cpan.org/Ticket/Display.html?id=94292
64 - the autolevels filter now works on the luminosity of the image
65 rather then working per channel. The old autolevels filter is
66 still available as "autolevels_skew".
67 https://rt.cpan.org/Ticket/Display.html?id=94413
69 - Imager::File::PNG now supports libpng 1.6.10.
70 1.6.10 changed CRC errors from benign errors to normal errors,
71 which broke the test which used CRC errors to check for benign
72 error support. Switched to using a 1-bit grey-scale image with a
73 palette to test for benign errors.
74 https://rt.cpan.org/Ticket/Display.html?id=94717
76 Imager 0.98 - 3 Jan 2014
81 - the return value of setpixel() has changed.
83 Previously the return values for undrawable pixels vs caller errors
84 changed depending on whether you used the multiple pixel calling
85 mechanism, or the single pixel mechanism.
89 - for an invalid parameter, such as an unknown colour, or missing
90 parameter, an empty list (or undef in scalar context) is
91 returned, and errstr() is set,
93 - otherwise the number of pixels drawn is returned. If none of
94 the pixels could be drawn (they were all outside the image), "0
95 but true" is returned.
97 https://rt.cpan.org/Ticket/Display.html?id=87650
101 - when drawing on an image with an alpha channel where the source
102 minimum is greater than zero, Imager would read from beyond the end
103 of a malloc() allocated buffer. In rare circumstances this could
104 lead to some of the source image not being written to the target
105 image, or possibly to a segmentation fault.
106 I don't believe this has any security concerns beyond that.
108 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
109 text drawn would be nonsense. This would also read beyond the end
110 of a malloced buffer.
112 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
114 https://rt.cpan.org/Ticket/Display.html?id=88993
116 - Imager::Font::Wrap no longer requires the image parameter.
117 https://rt.cpan.org/Ticket/Display.html?id=87338
119 - a documentation typo fix in Imager::Transformations
120 Thanks to Adrian Yee.
121 https://rt.cpan.org/Ticket/Display.html?id=88598
123 - Image::Probe, Imager's internal module for probing library
124 locations now searches the directories specified by LD_RUN_PATH,
125 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
126 and the corresponing s/\blib$/include/ directories for header
128 https://rt.cpan.org/Ticket/Display.html?id=86428
130 Imager 0.97 - 15 Jul 2013
133 No changes from 0.96_02.
135 Imager 0.96_02 - 8 Jul 2013
138 - PNG: treat a version mismatch between headers and library as a
140 https://rt.cpan.org/Ticket/Display.html?id=86659
142 - PNG: the check for benign error support is more complex than a
143 simple library version check, check for the appropriate macro.
144 Thanks for Slaven Rezic for following up on my CPAN Testers result
146 https://rt.cpan.org/Ticket/Display.html?id=86659
148 - W32: add a missing head1 AUTHORS to the old Win32.pm
149 https://rt.cpan.org/Ticket/Display.html?id=86658
151 Imager 0.96_01 - 1 Jul 2013
154 - TIFF: handle SampleFormat = 2 by translating the signed integer
155 values to unsigned by flipping their sign bits.
157 Handle SampleFormat = 3 where possible.
159 SampleFormat is ignored for paletted images.
161 Mixed SampleFormat are handled incorrectly, since libtiff returns
162 only the first SampleFormat value, and an image with both an alpha
163 channel and SampleFormat = 2 for color channels probably has a
164 different SampleFormat for the alpha channel.
166 https://rt.cpan.org/Ticket/Display.html?id=74540
169 https://rt.cpan.org/Ticket/Display.html?id=69243
171 - Imager::Color's rgba() method now returns its values as integers
172 instead of floating point. (IV instead of NV).
174 - The XS for i_map() and i_matrix_transform() now use the AV *
175 typemap instead of rolling their own.
177 - The XS for DSO_call() now uses the HV * typemap instead of
180 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
181 i_gradgen() now use a new T_AVARRAY typemap that greatly
182 simplifies the XS code.
184 - many other minor XS changes
186 - some XS code formatting
188 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
189 now renders in alpha-combining mode, to match antialiased output.
190 https://rt.cpan.org/Ticket/Display.html?id=73359
192 - add sample code and cookbook notes for drawing a blurred drop-shadow.
194 - add support for libpng 1.6, which changed the defaults for
195 reporting some types of error.
196 https://rt.cpan.org/Ticket/Display.html?id=85746
198 - FT2: use gsamp/psamp() to transfer pixels from the work image to
199 the output image instead of gpix/ppix.
200 https://rt.cpan.org/Ticket/Display.html?id=83478
202 - eliminate various GCC warnings, mostly initialized but otherwise
205 Imager 0.96 - 19 May 2013
208 - rearrange Imager's test files.
209 https://rt.cpan.org/Ticket/Display.html?id=84596
211 - Imager::Probe::_gcc_lib_paths now forces C locale.
212 A sufficiently recent gcc prints localized keys for the search
213 paths, which avoids that localization.
214 https://rt.cpan.org/Ticket/Display.html?id=84963
216 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
217 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
219 https://rt.cpan.org/Ticket/Display.html?id=85262
220 reported by Andreas König
222 - add a test for unclosed POD in C source, and fix the errors it
224 https://rt.cpan.org/Ticket/Display.html?id=74875
226 - fix some spelling errors detected by the newer aspell in Debian
229 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
230 thanks to gregor herrmann <gregoa@debian.org>
231 https://rt.cpan.org/Ticket/Display.html?id=85413
233 - add a test for standard =head1 commands and fix the errors found
235 Imager 0.95 - 19 Apr 2013
238 - handle the SVf_UTF8 flag correctly on magic strings passed to
239 Imager::IO's write() and raw_write() methods.
240 This may misbehave in perl 5.6.x since the UTF8 flag may not be
241 visible in the main SV after SvGETMAGIC().
242 https://rt.cpan.org/Ticket/Display.html?id=83438
244 - document that bounding_box() ignores the transformation matrix
245 supplied to tranform() for fonts.
246 https://rt.cpan.org/Ticket/Display.html?id=84106
248 Imager 0.94_02 - 5 Apr 2013
251 - enable debug logging for the standard font tests
253 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
254 due to a bug in that version of perl.
256 - don't test for read() failing on a write-only handle in 5.8.x and
257 earlier, this was fixed in change 862083f7e4 in perl.
259 - report the version of Inline found during testing (an attempt to
260 diagnose some intermittent failures.)
262 Imager 0.94_01 - 2 Mar 2013
265 - NOTE: possibly backward incompatible:
266 support reading from/writing to perl filehandes that aren't raw
269 This allows Imager's I/O to honour handles with layers such as
270 gzip, scalar file handles or tied file handles.
272 This is backward incompatible in that previous Imager would simply
273 use fileno() to retrieve the fd for the file and call write(2) etc
275 https://rt.cpan.org/Ticket/Display.html?id=78843
277 - moved most of README to lib/Imager/Install.pod which should make it
278 more accessible to the "web" generation, also significantly updated
281 - updated README's for the separately distributed modules to refer to
282 Imager::Install, and that they need -dev versions of packages
283 https://rt.cpan.org/Ticket/Display.html?id=81265
285 - the JPEG test code now reports the compile-time library version
287 - avoid a possible compiler optimization issue on CentOS 5.9 i386 by
288 rearranging (and mildly optimizing) some code.
289 https://rt.cpan.org/Ticket/Display.html?id=83212
291 - fix a POD error in Imager::Fill (detected on new Pod-Simple)
292 https://rt.cpan.org/Ticket/Display.html?id=83434
294 - fix a broken link to Graphics::Magick
295 https://rt.cpan.org/Ticket/Display.html?id=82743
297 - drawing text to a channel with FT2 would draw with random coverage
298 due to an uninitialized alpha channel.
300 - marked the function pointer underlying the mm_log() API with the
301 correct gcc magic and fixed the resulting warnings.
303 - fixed some other compiler warnings
305 - Imager::Font::W32 now properly reports text drawing errors
306 https://rt.cpan.org/Ticket/Display.html?id=70098
308 - handle the SVf_UTF8 flag correctly on magic (eg. overloaded)
309 strings passed as text to draw(), bounding_box(), has_chars(),
310 glyph_names() (where supported) in each of the font drivers.
311 This may misbehave in perl 5.6.x since the UTF8 flag may not be
312 visible in the main SV after SvGETMAGIC().
313 https://rt.cpan.org/Ticket/Display.html?id=83438 (partial)
315 Imager 0.94 - 15 Dec 2012
316 =========================
318 Variations on some of these changes were included in development
321 - improved thread safety
322 - the internal error stack and log file handle are now in a per-thread
324 - JPEG now captures IPTC information in a thread-safe way
325 - avoid globals where possible for warning capture in libtiff
326 - use a mutex to avoid re-entering thread-unsafe giflib
327 - use a mutex to avoid re-entering thread-unsafe tifflib
328 - use a mutex to avoid re-entering thread-unsafe T1Lib
329 - use a library handle per thread for freetype 2.
330 - use an engine handle per thread for freetype 1.x.
331 - originally these changes broke ABI compatibility, this has been
334 - clarify the return value of getpixel();
335 https://rt.cpan.org/Ticket/Display.html?id=81198
337 - fixed a race condition in parallel testing for T1
339 - fixed a bug in handling yoff for untransformed image-based fills
341 - documentation improvements for Imager::Fill
343 - FT2: report the library version while testing.
345 Imager 0.93 - 15 Oct 2012
350 - previously a transparency enabled GIF write (the default) would
351 always use a GIF89a header even if none of the images were
354 - previously the probe step for freetype-config would fail on cygwin
356 - catch an invalid matrix parameter to convert() instead of crashing
357 https://rt.cpan.org/Ticket/Display.html?id=79922
359 - remove the 16-bit/sample limitation from the documentation for
360 setsamples(), it hasn't applied for many releases.
361 https://rt.cpan.org/Ticket/Display.html?id=79989
363 - don't copy setsamples() data parameter, it may be a large scalar
364 https://rt.cpan.org/Ticket/Display.html?id=79990
366 - clean up .dSYM directories generated performing probes on OS X
369 - pass the --verbose command-line option through to Imager::Probe in
370 sub-module's Makefile.PLs
371 https://rt.cpan.org/Ticket/Display.html?id=75878
375 - support for giflib 5.0. (5.0.1 and later)
376 https://rt.cpan.org/Ticket/Display.html?id=79029
377 The giflib API Imager uses doesn't have a mechanism to set the
378 header version in 5.0.0.
380 - update the GIF library probe code to check for the new giflib 5.0.1
381 EGifSetGifVersion() function, and to check for the giflib 4.2.0
382 uninitialized gif89 bug.
383 https://rt.cpan.org/Ticket/Display.html?id=79679
384 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
386 - avoid static variables when capturing IPTC data from JPEG files
388 - match Imager::Font;:T1's error message translations to those from
389 later versions of T1Lib.
391 - for libtiff versions that support extended warning handlers (3.8.0
392 or later), use them to avoid some global variables.
394 - note Image::ExifTool for better metadata support.
395 https://rt.cpan.org/Ticket/Display.html?id=79251
397 Imager 0.92 - 14 Aug 2012
400 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
401 correctly for both probing and runtime.
402 https://rt.cpan.org/Ticket/Display.html?id=77672
404 - allow building JPEG/imexif.c on C89 compilers.
406 - allow building GIF/imgif.c on C89 compilers.
408 Imager 0.91 - 4 Jun 2012
413 - The size of rotated images is no longer rounded up so aggressively.
414 Added rounding to the linear interpolation done for rotate() and
415 matrix_transform() for 1 and 3 channel 8-bit images.
416 Adjusted the two tranlate matrices used to build the final rotation
417 matrix to use the distance between the outlier pixels rather than
418 the pixel dimensions (ie. dimension-1).
419 With all of this the output of rotate(degrees => 270) on an 8-bit
420 image exactly matches the output of rotate(right => 270).
421 https://rt.cpan.org/Ticket/Display.html?id=77063
425 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
426 internals, those names only matter for the XS interface.
428 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
429 the API level compiled into a loadable module such as
430 Imager::File::GIF doesn't match that of Imager. Previously it
431 could be difficult to determine exactly which module was failing to
433 https://rt.cpan.org/Ticket/Display.html?id=77173
435 - added Imager->check_file_limits() as an interface to the
436 i_int_check_image_file_limits() API.
438 - Imager->set_file_limits(reset => 1) now resets the limits to the
439 defaults rather than setting them all to unlimited.
441 - wrote a brief security note as Imager::Security
442 https://rt.cpan.org/Ticket/Display.html?id=68910
444 Imager 0.90 - 30 Apr 2012
449 - Imager::Test::is_imaged() attempted to process an "epsilon"
450 parameter but the prototype didn't allow for the extra parameter.
451 Corrected the prototype.
453 - when downconverting samples (eg. from floating point to 8 bit)
454 Imager now rounds the sample value rather than attempting to
455 allocate input values over output values equally. The old
456 behaviour had the probably surprising effect of converting a
457 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
459 This may result in slightly different 8 or 16-bit output images.
461 - BI_BITFIELD BMP images were handled incorrectly, both in
462 incorrectly calculating the space required for the masks and in
463 processing the image data itself.
464 https://rt.cpan.org/Ticket/Display.html?id=76736
466 - some odd width BMP BI_RLE4 images use run lengths that run one off
467 the edge of the image. Imager now allows this, discarding the
470 - odd length RLE4 runs in BMP images were decoded incorrectly.
472 - pkg-config could sometimes return a library that was in a directory
473 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
474 If no -L is included in the pkg-config library information check if
475 EU::MM can find the library, and if not, search our configured
476 directories and insert that into the library flags.
477 https://rt.cpan.org/Ticket/Display.html?id=75869
479 - Imager::Probe can now probe for libraries with dependent libraries,
480 common for static linking, eg. libpng requires libz.
481 https://rt.cpan.org/Ticket/Display.html?id=74043
483 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
485 - added alternative probe configurations that try to link libz, to
486 handle a statically linked libpng.
487 https://rt.cpan.org/Ticket/Display.html?id=74043
489 - if a probe includes testcode, Imager::Probe now checks that code as
490 part of the process of checking each configuration rather than as a
491 post test of the found configuration. This allows alternate
492 configurations to be checked if a matching but non-working
493 configuration is found.
494 https://rt.cpan.org/Ticket/Display.html?id=74043
498 - when reading or writing images via callbacks, the default callbacks
499 now push an error message indicating that a required callback was
500 called but not supplied.
501 https://rt.cpan.org/Ticket/Display.html?id=76782
503 - clarify which callbacks are required for reading and writing TIFF
506 - improve logging for creation of callback I/O layers.
508 - a little more documentation for Imager::Probe.
510 - the i_get_file_background() and i_get_file_backgroundf() APIs now
511 return int to indicate whether the i_background tag was found.
514 - improve error reporting
515 - add png_interlace, png_bits tags
516 - read paletted images as paletted images, including transparency
517 - read 1 bit greyscale images as a type suitable for other file
518 handlers to write as bilevel
519 - read 16 bit/sample PNG as 16-bit/sample Imager images
520 - write "bilevel" paletted images as 1 bit grayscale images
521 - write paletted images as paletted images
522 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
524 - improved metadata support
525 https://rt.cpan.org/Ticket/Display.html?id=29268
527 Imager 0.89 - 18 Mar 2012
532 - getpixel(..., type => "float") and the API i_gpixf() have been
533 broken on paletted images since they were implemented.
534 https://rt.cpan.org/Ticket/Display.html?id=75258
538 - links in the METHOD INDEX now point at the method documentation
539 rather than the heading you can find them under.
540 https://rt.cpan.org/Ticket/Display.html?id=71495
542 - Imager (and the bundled dynamic modules) no longer fallback to
543 using DynaLoader if loading via XSLoader fails.
544 For the bundled modules this could hide useful error messages.
545 https://rt.cpan.org/Ticket/Display.html?id=75560
547 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
548 buffer in the array of allocations, but just stores the filename
549 pointer and line number.
550 https://rt.cpan.org/Ticket/Display.html?id=70388
552 Imager 0.88 - 22 Feb 2012
555 - describe how to build libgif etc on OS X in such a way as to be
556 compatible with a fat binary perl (such as the system perl), in
558 https://rt.cpan.org/Ticket/Display.html?id=73371
560 - update the change notes for 0.77_01 to indicate that libungif
563 - add some other imaging modules to SEE ALSO
564 https://rt.cpan.org/Ticket/Display.html?id=73906
566 - note that the generator of the apparently non-DFSG-free postscript
567 in MMOne.pfb is a Debian package.
569 - setsamples() is now a true complement to getsamples() - it can
570 write 8-bit or floating point samples from a scalar or array
571 reference. This adds i_psamp() and i_psampf() to the C level API.
573 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
574 changed to make better use of the typemap, but these aren't part of
575 the perl level API anyway. There were no changes to the C level
576 interfaces to these functions.
578 - getpixel() and setpixel() now accept a mix of scalar and array
579 references for the x and y parameters, and unequal array lengths is
581 https://rt.cpan.org/Ticket/Display.html?id=73697
585 - correctly calculate the size of a rotated image
586 https://rt.cpan.org/Ticket/Display.html?id=69261
588 - fix incorrect rounding of color values for matrix_transform() and
590 https://rt.cpan.org/Ticket/Display.html?id=69261
592 - Win32 text output is now done in normal combine mode, the alpha
593 component of the color is now significant.
594 https://rt.cpan.org/Ticket/Display.html?id=70014
596 - remove long unused gif case from read()
597 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
599 - the getsamples() target parameter was being treated as a hashref
600 when it's meant to be an array reference.
601 https://rt.cpan.org/Ticket/Display.html?id=74882
603 - getpixel() and setpixel() now returns an empty list when invalid
604 parameters are supplied.
605 Invalid values for type now result in an error for getpixel().
606 https://rt.cpan.org/Ticket/Display.html?id=73697
608 Imager 0.87 - 03 Jan 2012
611 - document the return value of the filter() method.
612 https://rt.cpan.org/Ticket/Display.html?id=72369
614 - document i_gsamp_bits() and i_psamp_bits().
615 https://rt.cpan.org/Ticket/Display.html?id=68815
617 - properly increment the Imager::Matrix2d $VERSION.
619 - actually include the Imager::Test tests in the dist
621 - correctly read and write 256x256 pixel ICO files
622 https://rt.cpan.org/Ticket/Display.html?id=69599
624 - make the error message from read() or read_multi() when they can't
625 identify the file type match reality.
626 https://rt.cpan.org/Ticket/Display.html?id=72475
628 - read() now uses $FORMATGUESS if it can't determine the file type
629 based on the file header, to match read_multi().
631 - re-work and add tests for def_guess_type(). def_guess_type() no
632 longer returns any random file extension as the file type.
634 - add gray4, gray16 and gray as presets for make_colors.
635 https://rt.cpan.org/Ticket/Display.html?id=67911
637 - add make_palette() method that produces a palette from one or more
640 - fix the Imager dependency for the separately distributed font
642 https://rt.cpan.org/Ticket/Display.html?id=72643
644 - fix i_render_color() to properly draw in "normal" mode - ie. when
645 writing to a 1 or 3 channel image the second or fourth channel of
646 the source color was being ignored, it is now significant.
647 https://rt.cpan.org/Ticket/Display.html?id=71564
649 Imager 0.86 - 31 Oct 2011
652 - improve error reporting for W32 tests
654 Imager 0.85_02 - 24 Oct 2011
659 - eliminate unused i_gif_opts type (clean-up)
660 https://rt.cpan.org/Ticket/Display.html?id=69245
662 - fix combine=0 fill color anti-aliasing on the double/sample path
663 https://rt.cpan.org/Ticket/Display.html?id=71309
665 - make default text color non-transparent
666 https://rt.cpan.org/Ticket/Display.html?id=71469
668 - apply the last of the Debian unforwarded spelling fixes
669 https://rt.cpan.org/Ticket/Display.html?id=70656
671 - the log() method used its message parameter as a C level format
673 https://rt.cpan.org/Ticket/Display.html?id=71653
675 - provide our own STRLEN typemap entry for older perls.
676 https://rt.cpan.org/Ticket/Display.html?id=71641
678 - add extra ppport.h configuration to support older perls.
680 - depend on Scalar::Util, since we use it and older perls don't have
683 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
684 to synthesize it from overloaded "".
686 - use T1_StrError() for error messages on modern libt1
687 https://rt.cpan.org/Ticket/Display.html?id=69879
689 - actually load the font rather than just adding it to the catalog on
692 - Imager::Font->new now produces better error messages for the T1
695 - the font has_chars() method now returns perl's true and false
696 values in list context rather than integers, which should be more
698 https://rt.cpan.org/Ticket/Display.html?id=69158
700 - the btm data structure used by the flood_fill code is now
701 initialized more efficiently.
702 https://rt.cpan.org/Ticket/Display.html?id=68994
704 - updated the Thanks list in README
705 https://rt.cpan.org/Ticket/Display.html?id=71607
707 - check there's at least one coefficient for the convolution filter
708 https://rt.cpan.org/Ticket/Display.html?id=68993
710 - make the APIRef synopsis ordering consistent, older versions of
711 perl could order it differently.
712 https://rt.cpan.org/Ticket/Display.html?id=71675
714 - we rely on Config.pm's d_vsnprintf as to whether we use
715 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
716 though it only has _ prefixed versions of these. Define our own
717 prefixed names on Win32.
718 https://rt.cpan.org/Ticket/Display.html?id=71642
720 - fix library detection with MSVC
722 - search a few more library directories, so EU::MM doesn't discard
723 them. Hopefully fixes:
724 https://rt.cpan.org/Ticket/Display.html?id=71643
726 Imager 0.85_01 - 10 Oct 2011
729 - add simple tests for the Imager::Test test_image generators
731 - io_glue I/O buffering re-work:
733 - reorganize io_glue to do it's own buffering by default
735 - the unbuffered functions are available as i_io_raw_read() (or
736 raw_read() from perl) etc but are not recommended for typical
739 - use the new i_io_peekn() when checking for file magic to avoid
740 seek, allowing Imager to detect the file type and read the file
741 from an unseekable stream (for formats that don't use random
744 - added several new I/O layer API functions.
746 - fix the TGA performance problem, most noticably on Win32
747 https://rt.cpan.org/Ticket/Display.html?id=70037
749 - TIFF now uses wrapper functions of the correct types to avoid casts
750 https://rt.cpan.org/Ticket/Display.html?id=69912
752 - the callback IO object did its own buffering, controlled by the
753 maxbuffer parameter supplied to the read() and write() methods.
754 This buffering has been removed, to avoid redundancy with the
755 common io_glue buffering. This also avoids a bug in that code
756 which could rarely pass a zero length to the read callback and
757 then panic about the result.
759 - the callback IO object now tests the result of calling the close
760 callback, which should return true for success.
762 - the PNM reader did its own buffering. This buffering has been
763 removed to avoid redundancy with the common io_glue buffering.
765 - previously the read handlers for fd and callback I/O layers would
766 call the underlying interface (POSIX read or your supplied callback)
767 until it filled the buffer. It now only makes one call.
769 - added public constructors for I/O layer objects (see Imager::IO)
771 - all core file handlers now use the i_io_foo() wrappers to gain
772 access to buffered I/O rather than calling the I/O layer
775 - all core file handlers now check for error on close.
777 - Backward compatibility: if you hava custom file handlers, you can
778 use i_io_write() etc since they're available as macros in older
781 - eliminate the final remnants of io_glue_commit_types().
783 - bump IMAGER_API_VERSION, since the above may break assumptions.
785 - removed the long unused i_gen_reader() and i_gen_writer() utility
788 Imager 0.85 - 29 Aug 2011
791 The main changes in the release versus 0.84 are:
793 - on 64-bit systems, 64-bit types are consistently used for image
794 dimensions and co-ordinated, and for memory block sizes.
796 - handle IFD loops in TIFF files correctly. Previously this would
797 lead to an infinite loop.
801 - fix the link in the getheight() entry in the method index
803 Imager 0.84_02 - 22 Aug 2011
806 Development release, this will become 0.85 if CPAN testers is
811 - the image file limits set by set_file_limits() weren't being
812 checked when reading TIFF files.
813 https://rt.cpan.org/Ticket/Display.html?id=69915
815 - Provide more information about file format module load errors on a
816 failed image file read() or write().
817 https://rt.cpan.org/Ticket/Display.html?id=69194
819 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
820 through TIFF images, since it checks for IFD loops.
821 https://rt.cpan.org/Ticket/Display.html?id=69914
823 - don't leak memory when out of range palette indexes are supplied to
825 https://rt.cpan.org/Ticket/Display.html?id=69242
827 - require a later version of CPAN::Meta to ensure JSON::PP and
828 CPAN::Meta::YAML are available.
829 https://rt.cpan.org/Ticket/Display.html?id=69008
831 - hoist the per-line calculations for the flines implementations, and
832 modernize the tests a bit.
833 https://rt.cpan.org/Ticket/Display.html?id=70126
835 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
837 https://rt.cpan.org/Ticket/Display.html?id=69147
839 - if t1lib failed to reinitialize it would be left as marked
841 https://rt.cpan.org/Ticket/Display.html?id=69877
843 - update the bundled (and still modified) Devel::CheckLib
844 https://rt.cpan.org/Ticket/Display.html?id=69170
846 Imager 0.84_01 - 8 Aug 2011
849 Development release as a sanity check for the types re-work.
851 Massive types re-work:
853 - the type used internally for pixel co-ordinates and image sizes is
854 now 64-bit on 64-bit platforms (at least sane ones).
856 - size_t is now used consistently for memory block sizes.
858 - since this changes the binary interface, the Imager API version has
859 been incremented. Any module that uses the API will need to be
860 rebuilt. In most cases that will be enough, but calls to any APIs
861 that take a pointer to image sizes may need source changes.
863 - you should be able to create very large images on 64-bit systems,
864 if you have enough memory. Successfully created a 32768 x 49192 x
865 3 channel image, filled with a tiled image and scaled it. The
866 unscaled image was also successfully saved to a JPEG.
868 - check the image size before attempting to write BMP, GIF, JPEG,
869 PNG, SGI, TGA, TIFF images.
871 - correctly handle reading TGA images over 32767 pixels wide or tall.
875 - the gif_left and gif_top tags are now clamped to non-negative
876 values when writing a GIF image.
878 - removed dead callback read/write code
880 The default maximum memory size when reading files is now 1G.
882 Imager 0.84 - 20 Jun 2011
885 - Imager no longer inherits from Exporter (unless you're running an
888 - Imager can now write progressive JPEGs (it could always read them).
889 https://rt.cpan.org/Ticket/Display.html?id=68691
893 - re-work, document and test Imager's logging facility.
894 https://rt.cpan.org/Ticket/Display.html?id=65227
896 - fix META.yml testing and the generated META.yml
897 https://rt.cpan.org/Ticket/Display.html?id=65235
899 - test and add error reporting to to_*() family methods
901 - add to_rgb_double() method.
902 https://rt.cpan.org/Ticket/Display.html?id=65101
904 - Imager no longer exports anything by default
905 https://rt.cpan.org/Ticket/Display.html?id=65228
907 - convert colors to grayscale if the supplied (or generated) palette
908 contains only grays when performing error diffusion color
910 https://rt.cpan.org/Ticket/Display.html?id=68508
912 - writing a paletted image to GIF wouldn't always use the colors
913 supplied (or generated, eg. via make_colors => "mono"), which was
915 https://rt.cpan.org/Ticket/Display.html?id=67912
917 - replace (imager|tony)@imager.perl.org in the doc, since I don't
918 plan to continue receiving mail at that address.
919 https://rt.cpan.org/Ticket/Display.html?id=68591
921 Imager 0.83 - 21 May 2011
926 - diag() the error message on failure for some TIFF tests that are
927 failing on a Solaris smoker.
928 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
930 Imager 0.82_01 - 17 May 2011
933 Dev release, in case the compose tests are too sensitive.
937 - Imager::Font::T1 incorrectly checked for absolute filename under
938 Win32. Thanks to kmx for the report and fix.
939 https://rt.cpan.org/Ticket/Display.html?id=67963
941 - compose() with the target, source or mask position off the top or
942 left of the target image didn't clip the source image correctly.
943 https://rt.cpan.org/Ticket/Display.html?id=67220
945 - compose() now returns a useful error message on a non-positive
948 - compose.im now at 100% test coverage. (As opposed to, umm, much,
951 Imager 0.82 - 14 Mar 2011
956 - eliminate calls to i_has_format() from the test suite, since it's
957 no longer a useful way to check for file format support. Eliminate
958 i_has_format() from the functions exposed via XS.
959 https://rt.cpan.org/Ticket/Display.html?id=65863
961 - eliminate calls to note(), which isn't in the (very old) version of
962 Test::More we have as a pre-requisite. note() is modern enough
963 that I don't feel a need to require a Test::More upgrade for it.
964 https://rt.cpan.org/Ticket/Display.html?id=65864
966 - skip the threads tests on Test::More 2.00_*
967 https://rt.cpan.org/Ticket/Display.html?id=65812
969 - add an (unshipped) test to check Imager's internal POD links
970 https://rt.cpan.org/Ticket/Display.html?id=65749
972 - improve the library detection summary
973 https://rt.cpan.org/Ticket/Display.html?id=9675
975 - increase the version of Imager::Font::Type1 so that upgrades don't
976 downgrade the version in this file.
977 https://rt.cpan.org/Ticket/Display.html?id=66250
979 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
980 that option for the directories that would normally go in
981 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
982 https://rt.cpan.org/Ticket/Display.html?id=65955
984 Imager 0.81 - 14 Feb 2011
987 - added coverage tests for masked images (maskimg.c @100% test coverage)
989 - add hsv() method to Imager::Color
990 Thanks to Leolo (Philip Gwyn)
991 https://rt.cpan.org/Ticket/Display.html?id=65385
993 - split libt1 Type 1 font support into a sub-module
994 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
996 - add a preload() class method for use in forking servers, and to
997 work around limitations in PAR.
998 https://rt.cpan.org/Ticket/Display.html?id=65665
1002 - paletted writes to a masked image are now masked correctly.
1003 Revealed by new coverage tests.
1005 - update the filter plugin documentation.
1006 https://rt.cpan.org/Ticket/Display.html?id=56513
1008 - add the matrix() method to Imager::Matrix2d to allow creation of a
1009 matrix with specified co-efficients. You can now multiple an
1010 Imager::Matrix2d object by a 9 element array ref or a number.
1011 https://rt.cpan.org/Ticket/Display.html?id=29938
1013 - really fix loading TTF fonts with FT2 when FT1 isn't available.
1014 Thanks to Leolo (Philip Gwyn)
1015 https://rt.cpan.org/Ticket/Display.html?id=65386
1016 https://rt.cpan.org/Ticket/Display.html?id=62855
1018 - make sure each test script that needs testout/ creates it.
1019 https://rt.cpan.org/Ticket/Display.html?id=65088
1021 - handle a slightly different warning from libtiff 4.x
1022 https://rt.cpan.org/Ticket/Display.html?id=65268
1024 - the sat transform2() op returned an incorrect saturation.
1025 https://rt.cpan.org/Ticket/Display.html?id=65391
1027 Imager 0.80 - 17 Jan 2011
1030 - added coverage tests for Imager::Fountain and Imager::Color::Float
1032 - Imager is now maintained in git
1033 http://git.imager.perl.org/imager.git
1034 git://git.imager.perl.org/imager.git
1038 - images with an translucent alpha channel were not scaled correctly
1039 by the default (qtype=normal) scaling method.
1040 https://rt.cpan.org/Public/Bug/Display.html?id=63922
1042 - Imager::Color::Float now translates "#FFFFFF" to white instead of
1043 just a little darker.
1045 - make the default color map build algorithm "mediancut". This
1046 changes the default color map builder for writing GIFs back to what
1047 it was in 0.77, reverting a performance regression.
1048 https://rt.cpan.org/Ticket/Display.html?id=64785
1050 - handle failure to create a masked image correctly
1052 Imager 0.79 - 10 Dec 2010
1055 - add Imager::Test to the POD coverage tests and document the missing
1058 - the convert() method now optimizes the case where all output
1059 channels are either 0, sourced from a single input channel or 1.
1060 This significantly speeds up presets like "addalpha", "green".
1061 https://rt.cpan.org/Ticket/Display.html?id=51254
1063 - add wiggle.pl sample, as suggested by Dan Oppenheim.
1065 - add the combine() method to combine channels from multiple source
1066 images into a new image
1067 https://rt.cpan.org/Ticket/Display.html?id=11872
1071 - treat the co-efficients for convert() as doubles instead of floats.
1073 - If a higher (earlier) priority font handler failed to load, that
1074 would crash preventing loading of later font handlers.
1075 https://rt.cpan.org/Ticket/Display.html?id=62855
1077 - parse defines from the options returned by pkg-config --cflags
1078 https://rt.cpan.org/Ticket/Display.html?id=63223
1080 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
1081 included in the tarball. They are now included.
1083 Imager 0.78 - 4 Oct 2010
1088 - don't access deprecated members of the png_structp.
1089 https://rt.cpan.org/Ticket/Display.html?id=60242
1091 - document that using color objects is faster than supplying colors
1093 https://rt.cpan.org/Ticket/Display.html?id=61047
1095 - Imager::Probe now accepts array references for incpath and libpath.
1096 https://rt.cpan.org/Ticket/Display.html?id=60244
1098 Imager 0.77_02 - 27 Sep 2010
1101 - moved Win32, FreeType 2 font support into sub-modules.
1102 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1103 Uses Imager::Probe now.
1104 https://rt.cpan.org/Public/Bug/Display.html?id=61328
1106 - tested successfully with jpeg-8b
1107 https://rt.cpan.org/Ticket/Display.html?id=60221
1111 - from _01: look for missing file support test files in the right
1114 - flood_fill() wouldn't fill the right side of a single scan-line
1116 Thanks to Nicolas Roggli for reporting this.
1118 - flood_fill wouldn't fill to the left edge of the image if the
1119 starting line didn't reach the left edge.
1120 Thanks to Nicolas Roggli for reporting this.
1122 Imager 0.77_01 - 13 Sep 2010
1125 - add each library-directory/pkgconfig/ to the pkg-config search path
1127 Thanks to Justin Davis.
1128 https://rt.cpan.org/Ticket/Display.html?id=60491
1130 - moved GIF, TIFF, JPEG file handling code into sub-modules in
1131 preparation for separate distribution.
1132 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1134 Note: this removed support for libungif from Imager.
1136 - optimize filled box drawing (color, not fill)
1140 - Imager::Probe was calling ExtUtils::Liblist to initialize
1141 LD_RUN_PATH supplying an undefined value rather than the found
1142 directory. Thanks to Justin Davis.
1143 https://rt.cpan.org/Ticket/Display.html?id=60491
1145 - only prepend ./ to font filenames when passing them to T1Lib and
1146 then only when it would use its search mechanisms.
1147 https://rt.cpan.org/Ticket/Display.html?id=60509
1149 - fix the cache check for the X rgb.txt loader. This is typically
1150 used for color translation on Unix-like systems, and the fix
1151 improves performance of supplying colors by name by about 80 times.
1152 Test code that managed 3400 10x10 pixel boxes/second sped up to
1155 - clarify that Imager doesn't write EXIF metadata to images.
1156 https://rt.cpan.org/Ticket/Display.html?id=60637
1158 - Imager::Probe can now search subdirectories under its include path.
1159 Used by the PNG Makefile.PL to find headers and libraries when they
1160 aren't in the base directory, as in cygwin.
1161 https://rt.cpan.org/Ticket/Display.html?id=60635
1163 Imager 0.77 - 11 Aug 2010
1166 I don't want Imager::File::PNG indexed as part of Imager, but forgot
1167 to update the META.yml before updating the version.
1169 - don't index Imager::File::PNG as part of Imager
1171 - add resources to META.yml
1173 Imager 0.76 - not released
1178 - the align_string() method would ignore a string of "0" due to a
1179 mis-use of C< ||= >.
1180 Thanks to Maurice Height for reporting this.
1181 https://rt.cpan.org/Ticket/Display.html?id=60199
1183 Imager 0.75_03 - 09 Aug 2010
1188 - read_types() and write_types() would include png when it wasn't
1189 available due to a problem with the %formats tie
1191 - handle dependent libraries correctly (eg -lpng requiring -lz) in
1192 the code run phase of library probing.
1194 Imager 0.75_02 - 07 Aug 2010
1199 - add file missing from MANIFEST, which was causing TIFF failures.
1201 Imager 0.75_01 - 06 Aug 2010
1204 Test release for the new PNG probe.
1206 - added the ability to read multiple-image PNM files.
1207 Note that unlike the pbm/pgm/ppm specification this accepts mixed
1208 format files and allows white space padding between files.
1209 Thanks to Philip Gwyn (Leolo) for this patch.
1211 - moved the PNG file handling code into a sub-module in preparation
1212 for separate distribution.
1213 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1214 Also helps avoid complications from -I/-L compile/link options from
1219 - Imager->new(data => $data) didn't try to process image file data in
1221 https://rt.cpan.org/Ticket/Display.html?id=58761
1223 - t/t50basicoo.t no longer depends on the other tests to generate its
1225 https://rt.cpan.org/Ticket/Display.html?id=9798
1226 Also, it wasn't testing pnm (pnm vs ppm mix-up)
1228 - update the documentation of hardinvert to match the change in 0.62.
1229 https://rt.cpan.org/Ticket/Display.html?id=59785
1231 - added hardinvertall filter which also inverts the alpha channel
1232 (sorry for the mess)
1234 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
1235 the probe can find the library for the test run.
1236 https://rt.cpan.org/Ticket/Display.html?id=57518
1238 Imager 0.75 - 20 Jun 2010
1241 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
1242 perls (not measured)
1246 - an opacity fill based on a fountain fill would segfault when
1247 filling an 8-bit/sample image.
1249 - merge thickline branch polygon fix
1250 https://rt.cpan.org/Ticket/Display.html?id=43518
1252 Imager 0.74 - 7 May 2010
1257 - read_multi() didn't handle a missing file format library correctly,
1258 aborting on failing to call i_readgif_multi_wiol() or

1261 - fix spelling errors patched by Debian
1262 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
1264 - add an (unshipped) author test to spellcheck Imager's POD.
1266 - update the TIFF file format documentation
1267 https://rt.cpan.org/Ticket/Display.html?id=56510
1269 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
1271 Imager 0.73 - 15 Mar 2010
1274 - implement outline circles, both anti-aliased and not
1275 https://rt.cpan.org/Ticket/Display.html?id=19755
1277 - a combine => "none" fill to a 1 or 3 channel image would produce
1278 the incorrect colour.
1280 Imager 0.72 - 09 Dec 2009
1283 Bump version for release, since 0.71_03 is stable with CPAN testers.
1285 Imager 0.71_03 - 5 Dec 2009
1288 - further adjust the threads test so it only performs the tests on
1289 perls where it's expected to work, and only if the threads module
1292 Imager 0.71_02 - 1 Dec 2009
1295 - adjust the way we load the threads module for the threads test so
1296 it works with non-threaded perls
1298 Imager 0.71_01 - 30 Nov 2009
1303 - use scanline oriented operations to flip images instead of pixel
1305 https://rt.cpan.org/Ticket/Display.html?id=39278
1307 - use double/sample operations to flip large sample images instead of
1308 8-bit sample operations.
1309 https://rt.cpan.org/Ticket/Display.html?id=39280
1312 https://rt.cpan.org/Ticket/Display.html?id=51874
1314 - prevent double-frees when someone creates Imager objects and then
1315 creates a thread. Note: this just handles some simple cases,
1316 Imager doesn't support perl threads, and isn't likely to.
1317 https://rt.cpan.org/Ticket/Display.html?id=52268
1319 Imager 0.71 - 16 Nov 2009
1322 - add the opacity fill type - an adaptor that modifies the opacity of
1327 - the conv filter now enforces that the sum of the coefficients is
1328 non-zero. Also, rather than skipping pixels off the edge off the
1329 edge of the image, the closest edge pixel is used. Previously
1330 dividing by the zero sum of coefficients could cause invalid
1331 results or runtime exceptions.
1332 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
1335 Imager 0.70 - 21 Sep 2009
1340 - release image row and comments memory on all error returns in gif
1343 - handle zero length extensions, previously this would cause a null
1345 Thanks to Krzysztof WojtaÅ for the test data and fix for this.
1347 - an integer division meant that preview scaling to below 1 pixel
1348 wide or high (which isn't too useful anyway) was calculating using
1349 NaNs on most platforms, and causing an exception on others.
1350 Thanks to David Cantrell for producing a backtrace of the crash on
1351 his Alpha-NetBSD CPAN test box which made it possible to track this
1354 Imager 0.69 - 08 Sep 2009
1359 - broken test fix - was attempting to call a function skip_all, when
1360 that should be a parameter to plan().
1362 - briefly document apidocs.perl, the tool used to build
1363 Imager::APIRef and make some minor enhancements
1365 - various minor documentation enhancements and fixes.
1367 Imager 0.68 - 07 Sep 2009
1370 - Imager->new(file => $filename) and other similar incantations will
1371 load the given file.
1372 https://rt.cpan.org/Ticket/Display.html?id=48261
1376 - avoid using CHECK as a label in Imager::Test
1377 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
1379 - re-work most image file test files that require a library into
1380 separate library present/not present files to remove stupidly long
1383 - don't treat rubthrough() outside the bounds of the target image as
1385 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
1387 Imager 0.67_01 - 02 Sep 2009
1392 - correct documentation of default of raw image interleave read
1394 https://rt.cpan.org/Ticket/Display.html?id=42074
1396 - add raw_ prefix to raw read parameters, though the original names
1399 - fail the read if an invalid raw_interleave parameter is supplied
1401 - warn if no interleave or raw_interleave parameter is supplied,
1402 since the documented default was wrong, and incompatible with the
1405 - for reading raw images, if raw_storechannels > raw_datachannels,
1406 set the extra channels in the image to 0
1408 - when probing for executables like freetype-config, search for .bat
1409 and .cmd on MSWin32, as well as .exe.
1410 https://rt.cpan.org/Ticket/Display.html?id=49275
1412 - re-work the external libraries section of README:
1413 - list Debian and Redhat package names for each library
1417 - use the new EU::MM META_MERGE facility instead of generating
1418 META.yml from scratch
1419 https://rt.cpan.org/Ticket/Display.html?id=47888
1421 - use Devel::CheckLib (bundled, modified) to check which release of
1422 libtiff is installed and reject 3.9.0
1423 http://bugzilla.maptools.org/show_bug.cgi?id=2088
1424 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
1426 Imager 0.67 - 12 Dec 2008
1431 - fix a packaging error
1433 Imager 0.66 - 12 Dec 2008
1436 - 24-bit color .ICO/.CUR files can now be read.
1440 - an optimization skipping 0 src alpha values could cause the
1441 rubthrough() to read past the end of a buffer.
1442 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
1444 - corrected a reference leak where writing GIFs would leak memory.
1445 This could also happen calling to_paletted().
1446 Also documented the underlying long existing feature where the
1447 colors parameter is filled with the generated color table and added
1449 http://rt.cpan.org/Ticket/Display.html?id=41028
1451 - write out the image size in bytes field of a BMP correctly.
1452 http://rt.cpan.org/Ticket/Display.html?id=41406
1454 - add limited tests for Imager::ExtUtils
1456 - make Imager::ExtUtils->includes use an absolute path, since
1457 a relative path could cause failures using Inline::C.
1458 http://rt.cpan.org/Ticket/Display.html?id=37353
1460 - re-arrange the POD for Imager::Font::BBox:
1461 - mark total_width(), pos_width(), end_offset() obsolete, since
1462 they're mostly for backwards compatibility
1463 - group width methods and height methods
1464 https://rt.cpan.org/Ticket/Display.html?id=39999
1466 Imager 0.65 - 20 May 2008
1471 - In some cases when an error occurs reading those parts of a JPEG
1472 file after the image the scan-line buffer could be freed a second
1473 time. In cases where the the error occured while reading the image
1474 data it's possible that the buffer could have leaked.
1475 Thanks to Gabriel Vasseur for reporting this and help in tracking
1478 - the gif_screen_height tag was overriding the screen width and being
1479 ignored for the screen height when present.
1480 https://rt.cpan.org/Public/Bug/Display.html?id=35568
1482 Imager 0.64 - 23 April 2008
1485 This is a bug fix release. This includes a fix for a possible
1490 - Possible security issue: The floating point sample path for image
1491 based fills had a buffer overflow. This would overwrite the end of
1492 a malloc()ed buffer with double precision floats.
1493 http://rt.cpan.org/Ticket/Display.html?id=35324
1496 - check that the result of fileno($fh) is defined rather than simply
1497 true when read() or write() is supplied with an fh parameter.
1498 http://rt.cpan.org/Ticket/Display.html?id=35139
1500 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1501 resulting in a SIGSEGV when attempting to scale an image to a size
1502 too large to fit in memory. This is a NULL pointer access issue,
1503 not a buffer overflow.
1504 Added a check for the failure.
1505 scale_calculate() (and hence scale()) will now fail if any of the
1506 scale size parameters are a reference.
1507 http://rt.cpan.org/Ticket/Display.html?id=35172
1509 - Regression: filling a greyscale image with a hatch used the wrong
1510 color channels from the supplied fg/bg colors.
1511 https://rt.cpan.org/Ticket/Display.html?id=35278
1513 - fixed a related problem for image fills.
1515 Imager 0.63 - 7 April 2008
1518 This release primarily contains changes to improve ease of use -
1519 rather than you having to convert images to the appropriate number of
1520 channels, Imager handles it internally. How to handle drawing colors
1521 and the default combine mode is a thornier problem left for some other
1524 - the font libraries are now only initialized when needed.
1525 http://rt.cpan.org/Ticket/Display.html?id=28825
1527 - moved the imtoc.perl code into Imager::Preprocess
1529 - paste() and rubthrough() now adapt the source image data to the
1530 destination, so you can now safely paste/rubthrough from greyscale
1531 images to color images or back, or from alpha channel images to
1532 noalpha channels or back.
1533 https://rt.cpan.org/Ticket/Display.html?id=30908
1535 - rubthrough() now falls back to pasting when the source doesn't have
1536 an alpha channel. This effectively treats the source as having a
1537 max alpha channel, the right thing to do.
1538 http://rt.cpan.org/Ticket/Display.html?id=29944
1540 - re-worked most of the area filling code to use a common set of
1541 functions when filling.
1542 Corrected normal combine mode.
1543 Rewrote most of the combine modes to match the way the SVG draft
1544 defines them with respect to a translucent source and destination.
1545 Added tests for translucent source and destination.
1546 Added tests to check 8-bit/sample and double/sample combines work
1548 https://rt.cpan.org/Ticket/Display.html?id=29879
1550 - writing a 2 or 4 channel image to a JPEG file will now write that
1551 image as if composited against a background, black by default,
1552 overridable with the i_background tag/parameter.
1553 https://rt.cpan.org/Ticket/Display.html?id=29876
1555 - writing a 2 or 4 channel image to a PGM/PPM file will now write
1556 that image as if composited against a background, black by default,
1557 overridable with the i_background tag/parameter.
1558 http://rt.cpan.org/Ticket/Display.html?id=30074
1560 - writing a 2 or 4 channel image to a BMP file will now write that
1561 image as if composited against a background, black by default,
1562 overridable with the i_background tag/parameter.
1563 http://rt.cpan.org/Ticket/Display.html?id=30075
1567 - Imager::Matrix2d->translate() now only requires one of the x or y
1569 http://rt.cpan.org/Ticket/Display.html?id=29937
1571 - mixing qtype scaling now sets all channels of a pixel to zero if
1572 the pixel has zero coverage (zero alpha). This should produce more
1573 compressible output files.
1574 http://rt.cpan.org/Ticket/Display.html?id=32324
1576 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
1578 https://bugzilla.redhat.com/show_bug.cgi?id=166254
1579 I'm not changing the #! lines of the sample code, since it's sample
1580 code, not intended for installation.
1581 http://rt.cpan.org/Ticket/Display.html?id=33408
1583 - some TGA images weren't being detected correctly as TGA images
1584 https://rt.cpan.org/Ticket/Display.html?id=32925
1586 - handling of the left-over bit for 16-bit/pixel TGA images has been
1587 changed to match the behaviour of the GIMP. Previously the bit
1588 being set was treated as an opaque pixel, but one user reported a
1589 problem with loading such an image. I haven't been able to find any
1590 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1591 I'll match it's behaviour. See issue 114913 in the GIMP's
1593 http://rt.cpan.org/Ticket/Display.html?id=32926
1595 Imager 0.62 - 10 December 2007
1598 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
1599 to /path under your home directory.
1600 http://rt.cpan.org/Ticket/Display.html?id=29484
1602 - the old dynaload code used Mach API functions to load dynamic
1603 libraries on Mac OS X. These APIs have been deprecated in OS X
1604 10.5 and were causing some build problems.
1605 So henceforth Imager uses the dlopen() family of functions, and you
1606 will need version 10.3 or later of OS X.
1608 - added the det() function to the transform2() engine.
1609 added the sample quad_to_square.pl
1610 Courtesy Richard Fairhurst.
1611 http://rt.cpan.org/Ticket/Display.html?id=31244
1615 - samples/gifscale.pl sourced the base value for gif_top from
1617 Thanks to Eleneldil G. Arilou for pointing this out.
1619 - t/t82inline.t no longer loads B at runtime, to work around a bug
1620 in some 5.005_0[45] installations.
1621 http://rt.cpan.org/Ticket/Display.html?id=30508
1623 - work around Module::Depends::Intrusive bug #21229
1624 http://rt.cpan.org/Ticket/Display.html?id=30520
1626 - the hardinvert filter no-longer inverts the alpha channel.
1627 http://rt.cpan.org/Ticket/Display.html?id=30002
1629 - the hardinvert filter now supports large samples
1631 Imager 0.61_02 - 28 November 2007
1634 - major TIFF support re-work
1635 http://rt.cpan.org/Ticket/Display.html?id=20329
1637 - added a C level image interface for accessing samples from 1-32
1638 bits, exposed this at the perl level in getsamples()
1640 - the conv filter now works at floating point precision for high bit
1643 - added is_bilevel method to test whether an image should be written as
1644 a bilevel image if the image format supports it.
1646 - added -log-stderr as an Imager import list option
1648 - added some important types to Imager::APIRef
1650 - added test_image_double() to Imager::Test
1654 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
1657 - the scale() method with qtype mixing now handles images with an
1658 alpha channel correctly.
1660 - fixed a broken link from the "animated GIF" entry in the concept index.
1661 Thanks to Slaven Rezic.
1662 http://rt.cpan.org/Ticket/Display.html?id=30889
1664 - on some perl's the infix expression parser test would fail due to
1665 actions in the grammar returning false. Made sure all actions return
1667 Thanks to Richard Fairhurst for spending a lot of time in tracking
1669 http://rt.cpan.org/Public/Bug/Display.html?id=29562
1671 Imager 0.61 - 5 November 2007
1674 - added samples/gifscale.pl, which adjusts the screen size/position tags
1675 when scaling an animated gif
1676 http://rt.cpan.org/Ticket/Display.html?id=27591
1680 - correct handling of sz in matrix_transform() - this should allow
1681 perspective type transformations to work now.
1682 http://rt.cpan.org/Ticket/Display.html?id=29936
1684 - prevent a cast to integer warning on x64 builds in datatypes.c
1685 also fixed some other type warnings
1686 https://rt.cpan.org/Ticket/Display.html?id=30204
1688 - some sub-directory tests depended on files produced by the parent
1690 http://rt.cpan.org/Ticket/Display.html?id=30203
1692 - Imager::Font::Wrap doesn't correctly set savepos
1693 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
1694 http://rt.cpan.org/Ticket/Display.html?id=29771
1696 - test 171 in t/t01introvert.t was failing on perls configured to
1698 http://rt.cpan.org/Ticket/Display.html?id=29413
1700 - the code for the transform2() uminus operator was missing a break.
1701 Added tests for better code coverage of the ops.
1702 http://rt.cpan.org/Ticket/Display.html?id=29296
1704 - the SGI RLE compression code could overflow its compression buffer
1705 http://rt.cpan.org/Ticket/Display.html?id=30334
1707 - the 32-bit output function used by the SGI code only handled values
1708 under 0x10000. This was most noticable when writing large RLE images.
1709 http://rt.cpan.org/Ticket/Display.html?id=30335
1711 - validate chan_count for chans == NULL for each of the i_gsamp()
1713 http://rt.cpan.org/Ticket/Display.html?id=28985
1715 - attempt to work around the test failure at
1716 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
1717 http://rt.cpan.org/Ticket/Display.html?id=29562
1719 - improve the error messages produced when attempting to read or write
1720 an unknown image file format.
1721 http://rt.cpan.org/Ticket/Display.html?id=30103
1723 - improve the transform2() documentation
1724 http://rt.cpan.org/Ticket/Display.html?id=29267
1726 - correctly generate the author key in META.yml
1727 http://rt.cpan.org/Ticket/Display.html?id=30377
1729 - correctly blend a rotated (or matrix_transformed()) image when
1730 performing interpolation in the presence of an alpha channel.
1731 Also corrected the centring of the rotated image on the output
1734 Imager 0.60 - 30 August 2007
1737 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
1738 now has full SGI RGB image format, including RLE and 16-bit/sample
1740 https://rt.cpan.org/Ticket/Display.html?id=8666
1742 - logging functions are now available in the API
1744 - applied Gabriel Vasseur's patch
1745 added documentation, further tests, and support for greyscale images
1746 Obviously problems are my fault :)
1747 https://rt.cpan.org/Ticket/Display.html?id=28142
1749 - the mask for ICO/CUR images is now applied as an alpha channel to
1750 the returned image. For the old behaviour, supply ico_masked => 0
1751 to read() or read_multi(). This should be less confusing when
1752 using Imager as a general image processor.
1753 https://rt.cpan.org/Ticket/Display.html?id=29001
1757 - in some cases it's possible for giflib/libungif to return color
1758 indexes outside the range of colors defined by the image's palette.
1759 We now expand the palette to match the indexes used.
1760 Thanks to Gabriel Vasseur for reporting this.
1762 - fixed various memory leaks that could occur when failing to read png,
1763 jpeg, bmp or tga files.
1765 - to avoid confusion, channels not present in the image are returned as
1766 zero by getscanline(). This has no effect on the C level i_glin()
1767 and i_glinf() API functions which continue to not set the unused
1770 - the convert() method now returns an image of the same sample size as
1772 https://rt.cpan.org/Ticket/Display.html?id=28492
1774 - remove repeated text in Imager::Files
1775 http://rt.cpan.org/Ticket/Display.html?id=27589
1777 - be even more explicit that scale() and friends don't modify the source
1778 image, but return a new image.
1779 http://rt.cpan.org/Ticket/Display.html?id=28570
1781 - improve the error message from errstr() when you try to load a font
1782 for which the driver hasn't been built in Imager.
1783 http://rt.cpan.org/Ticket/Display.html?id=27571
1785 - transparency is now enabled by default when writing GIF images
1786 http://rt.cpan.org/Ticket/Display.html?id=27615
1788 - Imager would not load on Windows 98
1789 http://rt.cpan.org/Ticket/Display.html?id=27653
1791 Imager 0.59 - 14 June 2007
1796 - fixes a regression introduced by the fixes for RT 11972
1797 http://rt.cpan.org/Ticket/Display.html?id=27546
1799 - cropping outside the image would return an Imager object with
1800 no low-level image object, instead of returning false.
1801 Fixed by: Philip Gwyn (Leolo)
1802 http://rt.cpan.org/Ticket/Display.html?id=27509
1804 Imager 0.58 - 16 May 2007
1807 No significant changes from 0.57_01.
1809 Imager 0.57_01 - 11 May 2007
1812 - added to_rgb16 to produce a 16-bit/sample version of an image
1814 - improve freetype 1.x text output efficiency
1818 - search another place for rgb.txt, and check all the places
1819 Imager::Color checks when deciding whether to skip testing it
1820 http://rt.cpan.org/Ticket/Display.html?id=26064
1822 - use a convolution kernel size based on the stddev rather than a
1823 fixed size when performing a gaussian blur
1824 http://rt.cpan.org/Ticket/Display.html?id=25645
1826 - document the difference() method's mindist parameter, and debug it.
1828 - put the Imager release number in the Inline::C generated code to
1829 regenerate Inline code when a new release of Imager is installed.
1830 http://rt.cpan.org/Ticket/Display.html?id=26278
1832 - fix rendering on alpha channel images for the FreeType 1.x driver.
1833 http://rt.cpan.org/Ticket/Display.html?id=11972
1835 - fix rendering on alpha channel images for the T1lib driver.
1836 http://rt.cpan.org/Ticket/Display.html?id=11972
1838 - reworked library probing, we can now set more than one probe
1839 function for a library. Disabled the default (non-freetype-config)
1840 library probe and added an extra probe function that searches for
1841 both ft2build.h and whatever it includes, and adds -I as needed.
1842 Hopefully this will fix build problems like
1843 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
1844 http://rt.cpan.org/Ticket/Display.html?id=26086
1846 Imager 0.57 - 30 Apr 2007
1849 This is a maintenence release fixing a security issue in Imager.
1851 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
1852 overflow in malloced memory. There will be further discussion of
1853 this issue in the ticket below.
1854 http://rt.cpan.org/Ticket/Display.html?id=26811
1855 CVE-2007-2459 CVE-2007-2413
1856 The descriptions at cve.mitre.org varied in quality, please see the
1857 ticket at rt.cpan.org for a more accurate description of the issue.
1859 Imager 0.56 - 1 Apr 2007
1862 - added support for reading 16-bit/sample PGM/PPM images
1864 - added support for writing 16-bit/sample PGM/PPM images
1866 - improved performance of reading PBM/PGM/PPM images
1868 - added support for writing PBM images if the image is paletted and
1869 contains only black and white
1871 - added a new make_colors value - "mono"
1873 - switched from the svn log Changes to a manual Changes to reduce
1876 - new sample code - samples/flasher.pl
1880 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
1881 was returning an image object with an extra reference, this
1882 resulted in a memory leak.
1883 http://rt.cpan.org/Ticket/Display.html?id=24992
1885 - fix rendering on alpha channel images for the FreeType 2.x driver
1886 http://rt.cpan.org/Ticket/Display.html?id=11972
1888 - reading bmp files now consitently handles short reads. You can now
1889 supply a parameter to treat a short read as successful and set
1891 http://rt.cpan.org/Ticket/Display.html?id=8426
1893 - previously, reading ASCII PBM files required spaces between samples,
1894 even though the format doesn't require that
1896 - improved documentation of the unsharpmask filter (I hope)
1897 http://rt.cpan.org/Ticket/Display.html?id=25531
1899 - force flushing of the output from i_tt_dump_names() and test output
1900 in t/t35ttfont.t to prevent output from being mixed up.
1901 https://rt.cpan.org/Ticket/Display.html?id=24859
1903 - rewrite a conditional expression as an if() to hopefully work around
1904 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
1905 https://rt.cpan.org/Ticket/Display.html?id=25561
1907 - avoid Data::Dumper in regops.perl to support older releases of perl
1908 https://rt.cpan.org/Ticket/Display.html?id=24391
1910 Imager 0.55 - 16 Dec 2006
1913 This is primarily a bug fix release.
1915 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1917 There is one new feature:
1919 - the Win32 font driver now supports UTF8 (RT 22166)
1920 http://www.cpanforum.com/threads/3276
1921 http://rt.cpan.org/Ticket/Display.html?id=22166
1923 Several bugs were fixed:
1925 - the string() method would not output the string "0"
1926 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1928 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1929 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1931 - the gif_disposal and gif_user_input tags weren't being read from
1933 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1935 - gif.c was failing to build under MSVC
1936 http://rt.cpan.org/Ticket/Display.html?id=23922
1938 - in some cases strings passed to the string() method were treated as
1939 terminated by NUL (chr 0)
1940 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1942 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1943 that's the default build name for zlib on Win32.
1944 http://rt.cpan.org/Ticket/Display.html?id=23064
1946 - search $Config{incpath} for headers too, which we should have been
1949 Win32 font driver fixes:
1951 - the global descent value from bounding box was the wrong sign
1952 http://www.cpanforum.com/threads/3276
1954 - if the first or last glyph overflowed the left or right side of the
1955 advance width they would be clipped
1958 Imager 0.54 - 14 Sep 2006
1961 This is primarily a feature release:
1963 - a new qtype value 'mixing' has been added to the scale()
1964 method. This is faster than 'normal', slower than 'preview'. This
1965 is based on the method used by pnmscale, and seems to produce less
1966 blurry results than normal.
1967 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1969 - the rubthrough() method can now render onto images with an alpha
1971 http://rt.cpan.org/Ticket/Display.html?id=20678
1973 - the read_multi() method now falls back to calling doing a single
1974 image read via the read() method and write_multi() will now fall
1975 back to calling write() if a single image is supplied. This means
1976 you can simply call the read_multi() or write_multi() functions
1977 without having to check if the type is formatted by that method.
1978 http://rt.cpan.org/Ticket/Display.html?id=19457
1979 http://rt.cpan.org/Ticket/Display.html?id=19458
1981 - the GIF loop extension can now be written. If you don't have
1982 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1984 http://rt.cpan.org/Ticket/Display.html?id=21185
1986 - getscanline() and setscanline() can now read/write palette index
1987 based data from/to the image for paletted images, by setting type to
1989 http://rt.cpan.org/Ticket/Display.html?id=20338
1991 - we no longer hassle you to disable GIF support
1992 http://rt.cpan.org/Ticket/Display.html?id=20687
1994 - minor documentation fixes
1997 Imager 0.53 - 26 Jul 2006
2000 This is a bugfix release.
2002 Some test code was left in a code path not covered by the test
2003 suite. A test was added to cover this code path and the test code was

2008 Imager 0.52 - 25 Jul 2006
2011 This is primarily a feature release, but contains a fair few bug
2012 fixes, new features:
2014 - ability to read and write MS Windows ICO and CUR files
2016 - you can now add file format plugins to support new file formats
2018 - add POD coverage tests
2020 - setcolors() and addcolors() now accept color names and so on
2021 instead of requiring Imager::Color objects.
2022 http://rt.cpan.org/Ticket/Display.html?id=20056
2024 - flood_fill() can now fill to a specified border color instead of
2025 just to the area the same color as the seed.
2026 http://rt.cpan.org/Ticket/Display.html?id=19618
2031 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2032 calculating the advance width.
2033 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2035 - bounding_box for the T1 driver wasn't including leading and
2036 trailing spaces in the bounding box as the other drivers did, it also
2037 produced strange results for empty strings or strings containing only
2040 - when reading CMYK jpeg images they were being transferred to the
2041 image object as is, producing a four channel image. It only looked ok
2042 due to an old still unfixed Photoshop bug. We now convert from the
2043 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2044 http://rt.cpan.org/Ticket/Display.html?id=20416
2046 - reading a CYMK TIFF would result in a 4 channel image, reading any
2047 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2049 http://rt.cpan.org/Ticket/Display.html?id=20415
2051 - added /usr/local/include to the default include search path, since
2052 we were already searching /usr/local/lib for libraries.
2054 And various minor fixes and documentation updates.
2057 Imager 0.51 - 23 Apr 2006
2060 - fix a validation bug when processing JPEG EXIF data that can cause
2062 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2064 - fix mis-processing of the src_maxx and src_maxy parameters of the
2066 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2068 - fix a problem in Imager's "smart" handling of the color parameter
2070 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2073 Imager 0.50 - 29 Mar 2006
2076 - CRITICAL: fixes a segmentation fault from attempting to write a 2
2077 or 4 channel image to jpeg or a 2 channel image to tga where the
2078 output is an in-memeory buffer.
2079 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2081 - fixes an incorrect pointer parameter in the PNG code
2082 http://rt.cpan.org/Public/Bug/Display.html?id=18051
2084 - skip Inline::C tests when building in a directory with spaces
