1 Imager release history. Older releases can be found in Changes.old
3 Imager 0.94 - 15 Dec 2012
4 =========================
6 Variations on some of these changes were included in development
9 - improved thread safety
10 - the internal error stack and log file handle are now in a per-thread
12 - JPEG now captures IPTC information in a thread-safe way
13 - avoid globals where possible for warning capture in libtiff
14 - use a mutex to avoid re-entering thread-unsafe giflib
15 - use a mutex to avoid re-entering thread-unsafe tifflib
16 - use a mutex to avoid re-entering thread-unsafe T1Lib
17 - use a library handle per thread for freetype 2.
18 - use an engine handle per thread for freetype 1.x.
19 - originally these changes broke ABI compatibility, this has been
22 - clarify the return value of getpixel();
23 https://rt.cpan.org/Ticket/Display.html?id=81198
25 - fixed a race condition in parallel testing for T1
27 - fixed a bug in handling yoff for untransformed image-based fills
29 - documentation improvements for Imager::Fill
31 - FT2: report the library version while testing.
33 Imager 0.93 - 15 Oct 2012
38 - previously a transparency enabled GIF write (the default) would
39 always use a GIF89a header even if none of the images were
42 - previously the probe step for freetype-config would fail on cygwin
44 - catch an invalid matrix parameter to convert() instead of crashing
45 https://rt.cpan.org/Ticket/Display.html?id=79922
47 - remove the 16-bit/sample limitation from the documentation for
48 setsamples(), it hasn't applied for many releases.
49 https://rt.cpan.org/Ticket/Display.html?id=79989
51 - don't copy setsamples() data parameter, it may be a large scalar
52 https://rt.cpan.org/Ticket/Display.html?id=79990
54 - clean up .dSYM directories generated performing probes on OS X
57 - pass the --verbose command-line option through to Imager::Probe in
58 sub-module's Makefile.PLs
59 https://rt.cpan.org/Ticket/Display.html?id=75878
63 - support for giflib 5.0. (5.0.1 and later)
64 https://rt.cpan.org/Ticket/Display.html?id=79029
65 The giflib API Imager uses doesn't have a mechanism to set the
66 header version in 5.0.0.
68 - update the GIF library probe code to check for the new giflib 5.0.1
69 EGifSetGifVersion() function, and to check for the giflib 4.2.0
70 uninitialized gif89 bug.
71 https://rt.cpan.org/Ticket/Display.html?id=79679
72 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
74 - avoid static variables when capturing IPTC data from JPEG files
76 - match Imager::Font;:T1's error message translations to those from
77 later versions of T1Lib.
79 - for libtiff versions that support extended warning handlers (3.8.0
80 or later), use them to avoid some global variables.
82 - note Image::ExifTool for better metadata support.
83 https://rt.cpan.org/Ticket/Display.html?id=79251
85 Imager 0.92 - 14 Aug 2012
88 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
89 correctly for both probing and runtime.
90 https://rt.cpan.org/Ticket/Display.html?id=77672
92 - allow building JPEG/imexif.c on C89 compilers.
94 - allow building GIF/imgif.c on C89 compilers.
96 Imager 0.91 - 4 Jun 2012
101 - The size of rotated images is no longer rounded up so aggressively.
102 Added rounding to the linear interpolation done for rotate() and
103 matrix_transform() for 1 and 3 channel 8-bit images.
104 Adjusted the two tranlate matrices used to build the final rotation
105 matrix to use the distance between the outlier pixels rather than
106 the pixel dimensions (ie. dimension-1).
107 With all of this the output of rotate(degrees => 270) on an 8-bit
108 image exactly matches the output of rotate(right => 270).
109 https://rt.cpan.org/Ticket/Display.html?id=77063
113 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
114 internals, those names only matter for the XS interface.
116 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
117 the API level compiled into a loadable module such as
118 Imager::File::GIF doesn't match that of Imager. Previously it
119 could be difficult to determine exactly which module was failing to
121 https://rt.cpan.org/Ticket/Display.html?id=77173
123 - added Imager->check_file_limits() as an interface to the
124 i_int_check_image_file_limits() API.
126 - Imager->set_file_limits(reset => 1) now resets the limits to the
127 defaults rather than setting them all to unlimited.
129 - wrote a brief security note as Imager::Security
130 https://rt.cpan.org/Ticket/Display.html?id=68910
132 Imager 0.90 - 30 Apr 2012
137 - Imager::Test::is_imaged() attempted to process an "epsilon"
138 parameter but the prototype didn't allow for the extra parameter.
139 Corrected the prototype.
141 - when downconverting samples (eg. from floating point to 8 bit)
142 Imager now rounds the sample value rather than attempting to
143 allocate input values over output values equally. The old
144 behaviour had the probably surprising effect of converting a
145 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
147 This may result in slightly different 8 or 16-bit output images.
149 - BI_BITFIELD BMP images were handled incorrectly, both in
150 incorrectly calculating the space required for the masks and in
151 processing the image data itself.
152 https://rt.cpan.org/Ticket/Display.html?id=76736
154 - some odd width BMP BI_RLE4 images use run lengths that run one off
155 the edge of the image. Imager now allows this, discarding the
158 - odd length RLE4 runs in BMP images were decoded incorrectly.
160 - pkg-config could sometimes return a library that was in a directory
161 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
162 If no -L is included in the pkg-config library information check if
163 EU::MM can find the library, and if not, search our configured
164 directories and insert that into the library flags.
165 https://rt.cpan.org/Ticket/Display.html?id=75869
167 - Imager::Probe can now probe for libraries with dependent libraries,
168 common for static linking, eg. libpng requires libz.
169 https://rt.cpan.org/Ticket/Display.html?id=74043
171 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
173 - added alternative probe configurations that try to link libz, to
174 handle a statically linked libpng.
175 https://rt.cpan.org/Ticket/Display.html?id=74043
177 - if a probe includes testcode, Imager::Probe now checks that code as
178 part of the process of checking each configuration rather than as a
179 post test of the found configuration. This allows alternate
180 configurations to be checked if a matching but non-working
181 configuration is found.
182 https://rt.cpan.org/Ticket/Display.html?id=74043
186 - when reading or writing images via callbacks, the default callbacks
187 now push an error message indicating that a required callback was
188 called but not supplied.
189 https://rt.cpan.org/Ticket/Display.html?id=76782
191 - clarify which callbacks are required for reading and writing TIFF
194 - improve logging for creation of callback I/O layers.
196 - a little more documentation for Imager::Probe.
198 - the i_get_file_background() and i_get_file_backgroundf() APIs now
199 return int to indicate whether the i_background tag was found.
202 - improve error reporting
203 - add png_interlace, png_bits tags
204 - read paletted images as paletted images, including transparency
205 - read 1 bit greyscale images as a type suitable for other file
206 handlers to write as bilevel
207 - read 16 bit/sample PNG as 16-bit/sample Imager images
208 - write "bilevel" paletted images as 1 bit grayscale images
209 - write paletted images as paletted images
210 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
212 - improved metadata support
213 https://rt.cpan.org/Ticket/Display.html?id=29268
215 Imager 0.89 - 18 Mar 2012
220 - getpixel(..., type => "float") and the API i_gpixf() have been
221 broken on paletted images since they were implemented.
222 https://rt.cpan.org/Ticket/Display.html?id=75258
226 - links in the METHOD INDEX now point at the method documentation
227 rather than the heading you can find them under.
228 https://rt.cpan.org/Ticket/Display.html?id=71495
230 - Imager (and the bundled dynamic modules) no longer fallback to
231 using DynaLoader if loading via XSLoader fails.
232 For the bundled modules this could hide useful error messages.
233 https://rt.cpan.org/Ticket/Display.html?id=75560
235 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
236 buffer in the array of allocations, but just stores the filename
237 pointer and line number.
238 https://rt.cpan.org/Ticket/Display.html?id=70388
240 Imager 0.88 - 22 Feb 2012
243 - describe how to build libgif etc on OS X in such a way as to be
244 compatible with a fat binary perl (such as the system perl), in
246 https://rt.cpan.org/Ticket/Display.html?id=73371
248 - update the change notes for 0.77_01 to indicate that libungif
251 - add some other imaging modules to SEE ALSO
252 https://rt.cpan.org/Ticket/Display.html?id=73906
254 - note that the generator of the apparently non-DFSG-free postscript
255 in MMOne.pfb is a Debian package.
257 - setsamples() is now a true complement to getsamples() - it can
258 write 8-bit or floating point samples from a scalar or array
259 reference. This adds i_psamp() and i_psampf() to the C level API.
261 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
262 changed to make better use of the typemap, but these aren't part of
263 the perl level API anyway. There were no changes to the C level
264 interfaces to these functions.
266 - getpixel() and setpixel() now accept a mix of scalar and array
267 references for the x and y parameters, and unequal array lengths is
269 https://rt.cpan.org/Ticket/Display.html?id=73697
273 - correctly calculate the size of a rotated image
274 https://rt.cpan.org/Ticket/Display.html?id=69261
276 - fix incorrect rounding of color values for matrix_transform() and
278 https://rt.cpan.org/Ticket/Display.html?id=69261
280 - Win32 text output is now done in normal combine mode, the alpha
281 component of the color is now significant.
282 https://rt.cpan.org/Ticket/Display.html?id=70014
284 - remove long unused gif case from read()
285 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
287 - the getsamples() target parameter was being treated as a hashref
288 when it's meant to be an array reference.
289 https://rt.cpan.org/Ticket/Display.html?id=74882
291 - getpixel() and setpixel() now returns an empty list when invalid
292 parameters are supplied.
293 Invalid values for type now result in an error for getpixel().
294 https://rt.cpan.org/Ticket/Display.html?id=73697
296 Imager 0.87 - 03 Jan 2012
299 - document the return value of the filter() method.
300 https://rt.cpan.org/Ticket/Display.html?id=72369
302 - document i_gsamp_bits() and i_psamp_bits().
303 https://rt.cpan.org/Ticket/Display.html?id=68815
305 - properly increment the Imager::Matrix2d $VERSION.
307 - actually include the Imager::Test tests in the dist
309 - correctly read and write 256x256 pixel ICO files
310 https://rt.cpan.org/Ticket/Display.html?id=69599
312 - make the error message from read() or read_multi() when they can't
313 identify the file type match reality.
314 https://rt.cpan.org/Ticket/Display.html?id=72475
316 - read() now uses $FORMATGUESS if it can't determine the file type
317 based on the file header, to match read_multi().
319 - re-work and add tests for def_guess_type(). def_guess_type() no
320 longer returns any random file extension as the file type.
322 - add gray4, gray16 and gray as presets for make_colors.
323 https://rt.cpan.org/Ticket/Display.html?id=67911
325 - add make_palette() method that produces a palette from one or more
328 - fix the Imager dependency for the separately distributed font
330 https://rt.cpan.org/Ticket/Display.html?id=72643
332 - fix i_render_color() to properly draw in "normal" mode - ie. when
333 writing to a 1 or 3 channel image the second or fourth channel of
334 the source color was being ignored, it is now significant.
335 https://rt.cpan.org/Ticket/Display.html?id=71564
337 Imager 0.86 - 31 Oct 2011
340 - improve error reporting for W32 tests
342 Imager 0.85_02 - 24 Oct 2011
347 - eliminate unused i_gif_opts type (clean-up)
348 https://rt.cpan.org/Ticket/Display.html?id=69245
350 - fix combine=0 fill color anti-aliasing on the double/sample path
351 https://rt.cpan.org/Ticket/Display.html?id=71309
353 - make default text color non-transparent
354 https://rt.cpan.org/Ticket/Display.html?id=71469
356 - apply the last of the Debian unforwarded spelling fixes
357 https://rt.cpan.org/Ticket/Display.html?id=70656
359 - the log() method used its message parameter as a C level format
361 https://rt.cpan.org/Ticket/Display.html?id=71653
363 - provide our own STRLEN typemap entry for older perls.
364 https://rt.cpan.org/Ticket/Display.html?id=71641
366 - add extra ppport.h configuration to support older perls.
368 - depend on Scalar::Util, since we use it and older perls don't have
371 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
372 to synthesize it from overloaded "".
374 - use T1_StrError() for error messages on modern libt1
375 https://rt.cpan.org/Ticket/Display.html?id=69879
377 - actually load the font rather than just adding it to the catalog on
380 - Imager::Font->new now produces better error messages for the T1
383 - the font has_chars() method now returns perl's true and false
384 values in list context rather than integers, which should be more
386 https://rt.cpan.org/Ticket/Display.html?id=69158
388 - the btm data structure used by the flood_fill code is now
389 initialized more efficiently.
390 https://rt.cpan.org/Ticket/Display.html?id=68994
392 - updated the Thanks list in README
393 https://rt.cpan.org/Ticket/Display.html?id=71607
395 - check there's at least one coefficient for the convolution filter
396 https://rt.cpan.org/Ticket/Display.html?id=68993
398 - make the APIRef synopsis ordering consistent, older versions of
399 perl could order it differently.
400 https://rt.cpan.org/Ticket/Display.html?id=71675
402 - we rely on Config.pm's d_vsnprintf as to whether we use
403 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
404 though it only has _ prefixed versions of these. Define our own
405 prefixed names on Win32.
406 https://rt.cpan.org/Ticket/Display.html?id=71642
408 - fix library detection with MSVC
410 - search a few more library directories, so EU::MM doesn't discard
411 them. Hopefully fixes:
412 https://rt.cpan.org/Ticket/Display.html?id=71643
414 Imager 0.85_01 - 10 Oct 2011
417 - add simple tests for the Imager::Test test_image generators
419 - io_glue I/O buffering re-work:
421 - reorganize io_glue to do it's own buffering by default
423 - the unbuffered functions are available as i_io_raw_read() (or
424 raw_read() from perl) etc but are not recommended for typical
427 - use the new i_io_peekn() when checking for file magic to avoid
428 seek, allowing Imager to detect the file type and read the file
429 from an unseekable stream (for formats that don't use random
432 - added several new I/O layer API functions.
434 - fix the TGA performance problem, most noticably on Win32
435 https://rt.cpan.org/Ticket/Display.html?id=70037
437 - TIFF now uses wrapper functions of the correct types to avoid casts
438 https://rt.cpan.org/Ticket/Display.html?id=69912
440 - the callback IO object did its own buffering, controlled by the
441 maxbuffer parameter supplied to the read() and write() methods.
442 This buffering has been removed, to avoid redundancy with the
443 common io_glue buffering. This also avoids a bug in that code
444 which could rarely pass a zero length to the read callback and
445 then panic about the result.
447 - the callback IO object now tests the result of calling the close
448 callback, which should return true for success.
450 - the PNM reader did its own buffering. This buffering has been
451 removed to avoid redundancy with the common io_glue buffering.
453 - previously the read handlers for fd and callback I/O layers would
454 call the underlying interface (POSIX read or your supplied callback)
455 until it filled the buffer. It now only makes one call.
457 - added public constructors for I/O layer objects (see Imager::IO)
459 - all core file handlers now use the i_io_foo() wrappers to gain
460 access to buffered I/O rather than calling the I/O layer
463 - all core file handlers now check for error on close.
465 - Backward compatibility: if you hava custom file handlers, you can
466 use i_io_write() etc since they're available as macros in older
469 - eliminate the final remnants of io_glue_commit_types().
471 - bump IMAGER_API_VERSION, since the above may break assumptions.
473 - removed the long unused i_gen_reader() and i_gen_writer() utility
476 Imager 0.85 - 29 Aug 2011
479 The main changes in the release versus 0.84 are:
481 - on 64-bit systems, 64-bit types are consistently used for image
482 dimensions and co-ordinated, and for memory block sizes.
484 - handle IFD loops in TIFF files correctly. Previously this would
485 lead to an infinite loop.
489 - fix the link in the getheight() entry in the method index
491 Imager 0.84_02 - 22 Aug 2011
494 Development release, this will become 0.85 if CPAN testers is
499 - the image file limits set by set_file_limits() weren't being
500 checked when reading TIFF files.
501 https://rt.cpan.org/Ticket/Display.html?id=69915
503 - Provide more information about file format module load errors on a
504 failed image file read() or write().
505 https://rt.cpan.org/Ticket/Display.html?id=69194
507 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
508 through TIFF images, since it checks for IFD loops.
509 https://rt.cpan.org/Ticket/Display.html?id=69914
511 - don't leak memory when out of range palette indexes are supplied to
513 https://rt.cpan.org/Ticket/Display.html?id=69242
515 - require a later version of CPAN::Meta to ensure JSON::PP and
516 CPAN::Meta::YAML are available.
517 https://rt.cpan.org/Ticket/Display.html?id=69008
519 - hoist the per-line calculations for the flines implementations, and
520 modernize the tests a bit.
521 https://rt.cpan.org/Ticket/Display.html?id=70126
523 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
525 https://rt.cpan.org/Ticket/Display.html?id=69147
527 - if t1lib failed to reinitialize it would be left as marked
529 https://rt.cpan.org/Ticket/Display.html?id=69877
531 - update the bundled (and still modified) Devel::CheckLib
532 https://rt.cpan.org/Ticket/Display.html?id=69170
534 Imager 0.84_01 - 8 Aug 2011
537 Development release as a sanity check for the types re-work.
539 Massive types re-work:
541 - the type used internally for pixel co-ordinates and image sizes is
542 now 64-bit on 64-bit platforms (at least sane ones).
544 - size_t is now used consistently for memory block sizes.
546 - since this changes the binary interface, the Imager API version has
547 been incremented. Any module that uses the API will need to be
548 rebuilt. In most cases that will be enough, but calls to any APIs
549 that take a pointer to image sizes may need source changes.
551 - you should be able to create very large images on 64-bit systems,
552 if you have enough memory. Successfully created a 32768 x 49192 x
553 3 channel image, filled with a tiled image and scaled it. The
554 unscaled image was also successfully saved to a JPEG.
556 - check the image size before attempting to write BMP, GIF, JPEG,
557 PNG, SGI, TGA, TIFF images.
559 - correctly handle reading TGA images over 32767 pixels wide or tall.
563 - the gif_left and gif_top tags are now clamped to non-negative
564 values when writing a GIF image.
566 - removed dead callback read/write code
568 The default maximum memory size when reading files is now 1G.
570 Imager 0.84 - 20 Jun 2011
573 - Imager no longer inherits from Exporter (unless you're running an
576 - Imager can now write progressive JPEGs (it could always read them).
577 https://rt.cpan.org/Ticket/Display.html?id=68691
581 - re-work, document and test Imager's logging facility.
582 https://rt.cpan.org/Ticket/Display.html?id=65227
584 - fix META.yml testing and the generated META.yml
585 https://rt.cpan.org/Ticket/Display.html?id=65235
587 - test and add error reporting to to_*() family methods
589 - add to_rgb_double() method.
590 https://rt.cpan.org/Ticket/Display.html?id=65101
592 - Imager no longer exports anything by default
593 https://rt.cpan.org/Ticket/Display.html?id=65228
595 - convert colors to grayscale if the supplied (or generated) palette
596 contains only grays when performing error diffusion color
598 https://rt.cpan.org/Ticket/Display.html?id=68508
600 - writing a paletted image to GIF wouldn't always use the colors
601 supplied (or generated, eg. via make_colors => "mono"), which was
603 https://rt.cpan.org/Ticket/Display.html?id=67912
605 - replace (imager|tony)@imager.perl.org in the doc, since I don't
606 plan to continue receiving mail at that address.
607 https://rt.cpan.org/Ticket/Display.html?id=68591
609 Imager 0.83 - 21 May 2011
614 - diag() the error message on failure for some TIFF tests that are
615 failing on a Solaris smoker.
616 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
618 Imager 0.82_01 - 17 May 2011
621 Dev release, in case the compose tests are too sensitive.
625 - Imager::Font::T1 incorrectly checked for absolute filename under
626 Win32. Thanks to kmx for the report and fix.
627 https://rt.cpan.org/Ticket/Display.html?id=67963
629 - compose() with the target, source or mask position off the top or
630 left of the target image didn't clip the source image correctly.
631 https://rt.cpan.org/Ticket/Display.html?id=67220
633 - compose() now returns a useful error message on a non-positive
636 - compose.im now at 100% test coverage. (As opposed to, umm, much,
639 Imager 0.82 - 14 Mar 2011
644 - eliminate calls to i_has_format() from the test suite, since it's
645 no longer a useful way to check for file format support. Eliminate
646 i_has_format() from the functions exposed via XS.
647 https://rt.cpan.org/Ticket/Display.html?id=65863
649 - eliminate calls to note(), which isn't in the (very old) version of
650 Test::More we have as a pre-requisite. note() is modern enough
651 that I don't feel a need to require a Test::More upgrade for it.
652 https://rt.cpan.org/Ticket/Display.html?id=65864
654 - skip the threads tests on Test::More 2.00_*
655 https://rt.cpan.org/Ticket/Display.html?id=65812
657 - add an (unshipped) test to check Imager's internal POD links
658 https://rt.cpan.org/Ticket/Display.html?id=65749
660 - improve the library detection summary
661 https://rt.cpan.org/Ticket/Display.html?id=9675
663 - increase the version of Imager::Font::Type1 so that upgrades don't
664 downgrade the version in this file.
665 https://rt.cpan.org/Ticket/Display.html?id=66250
667 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
668 that option for the directories that would normally go in
669 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
670 https://rt.cpan.org/Ticket/Display.html?id=65955
672 Imager 0.81 - 14 Feb 2011
675 - added coverage tests for masked images (maskimg.c @100% test coverage)
677 - add hsv() method to Imager::Color
678 Thanks to Leolo (Philip Gwyn)
679 https://rt.cpan.org/Ticket/Display.html?id=65385
681 - split libt1 Type 1 font support into a sub-module
682 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
684 - add a preload() class method for use in forking servers, and to
685 work around limitations in PAR.
686 https://rt.cpan.org/Ticket/Display.html?id=65665
690 - paletted writes to a masked image are now masked correctly.
691 Revealed by new coverage tests.
693 - update the filter plugin documentation.
694 https://rt.cpan.org/Ticket/Display.html?id=56513
696 - add the matrix() method to Imager::Matrix2d to allow creation of a
697 matrix with specified co-efficients. You can now multiple an
698 Imager::Matrix2d object by a 9 element array ref or a number.
699 https://rt.cpan.org/Ticket/Display.html?id=29938
701 - really fix loading TTF fonts with FT2 when FT1 isn't available.
702 Thanks to Leolo (Philip Gwyn)
703 https://rt.cpan.org/Ticket/Display.html?id=65386
704 https://rt.cpan.org/Ticket/Display.html?id=62855
706 - make sure each test script that needs testout/ creates it.
707 https://rt.cpan.org/Ticket/Display.html?id=65088
709 - handle a slightly different warning from libtiff 4.x
710 https://rt.cpan.org/Ticket/Display.html?id=65268
712 - the sat transform2() op returned an incorrect saturation.
713 https://rt.cpan.org/Ticket/Display.html?id=65391
715 Imager 0.80 - 17 Jan 2011
718 - added coverage tests for Imager::Fountain and Imager::Color::Float
720 - Imager is now maintained in git
721 http://git.imager.perl.org/imager.git
722 git://git.imager.perl.org/imager.git
726 - images with an translucent alpha channel were not scaled correctly
727 by the default (qtype=normal) scaling method.
728 https://rt.cpan.org/Public/Bug/Display.html?id=63922
730 - Imager::Color::Float now translates "#FFFFFF" to white instead of
731 just a little darker.
733 - make the default color map build algorithm "mediancut". This
734 changes the default color map builder for writing GIFs back to what
735 it was in 0.77, reverting a performance regression.
736 https://rt.cpan.org/Ticket/Display.html?id=64785
738 - handle failure to create a masked image correctly
740 Imager 0.79 - 10 Dec 2010
743 - add Imager::Test to the POD coverage tests and document the missing
746 - the convert() method now optimizes the case where all output
747 channels are either 0, sourced from a single input channel or 1.
748 This significantly speeds up presets like "addalpha", "green".
749 https://rt.cpan.org/Ticket/Display.html?id=51254
751 - add wiggle.pl sample, as suggested by Dan Oppenheim.
753 - add the combine() method to combine channels from multiple source
754 images into a new image
755 https://rt.cpan.org/Ticket/Display.html?id=11872
759 - treat the co-efficients for convert() as doubles instead of floats.
761 - If a higher (earlier) priority font handler failed to load, that
762 would crash preventing loading of later font handlers.
763 https://rt.cpan.org/Ticket/Display.html?id=62855
765 - parse defines from the options returned by pkg-config --cflags
766 https://rt.cpan.org/Ticket/Display.html?id=63223
768 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
769 included in the tarball. They are now included.
771 Imager 0.78 - 4 Oct 2010
776 - don't access deprecated members of the png_structp.
777 https://rt.cpan.org/Ticket/Display.html?id=60242
779 - document that using color objects is faster than supplying colors
781 https://rt.cpan.org/Ticket/Display.html?id=61047
783 - Imager::Probe now accepts array references for incpath and libpath.
784 https://rt.cpan.org/Ticket/Display.html?id=60244
786 Imager 0.77_02 - 27 Sep 2010
789 - moved Win32, FreeType 2 font support into sub-modules.
790 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
791 Uses Imager::Probe now.
792 https://rt.cpan.org/Public/Bug/Display.html?id=61328
794 - tested successfully with jpeg-8b
795 https://rt.cpan.org/Ticket/Display.html?id=60221
799 - from _01: look for missing file support test files in the right
802 - flood_fill() wouldn't fill the right side of a single scan-line
804 Thanks to Nicolas Roggli for reporting this.
806 - flood_fill wouldn't fill to the left edge of the image if the
807 starting line didn't reach the left edge.
808 Thanks to Nicolas Roggli for reporting this.
810 Imager 0.77_01 - 13 Sep 2010
813 - add each library-directory/pkgconfig/ to the pkg-config search path
815 Thanks to Justin Davis.
816 https://rt.cpan.org/Ticket/Display.html?id=60491
818 - moved GIF, TIFF, JPEG file handling code into sub-modules in
819 preparation for separate distribution.
820 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
822 Note: this removed support for libungif from Imager.
824 - optimize filled box drawing (color, not fill)
828 - Imager::Probe was calling ExtUtils::Liblist to initialize
829 LD_RUN_PATH supplying an undefined value rather than the found
830 directory. Thanks to Justin Davis.
831 https://rt.cpan.org/Ticket/Display.html?id=60491
833 - only prepend ./ to font filenames when passing them to T1Lib and
834 then only when it would use its search mechanisms.
835 https://rt.cpan.org/Ticket/Display.html?id=60509
837 - fix the cache check for the X rgb.txt loader. This is typically
838 used for color translation on Unix-like systems, and the fix
839 improves performance of supplying colors by name by about 80 times.
840 Test code that managed 3400 10x10 pixel boxes/second sped up to
843 - clarify that Imager doesn't write EXIF metadata to images.
844 https://rt.cpan.org/Ticket/Display.html?id=60637
846 - Imager::Probe can now search subdirectories under its include path.
847 Used by the PNG Makefile.PL to find headers and libraries when they
848 aren't in the base directory, as in cygwin.
849 https://rt.cpan.org/Ticket/Display.html?id=60635
851 Imager 0.77 - 11 Aug 2010
854 I don't want Imager::File::PNG indexed as part of Imager, but forgot
855 to update the META.yml before updating the version.
857 - don't index Imager::File::PNG as part of Imager
859 - add resources to META.yml
861 Imager 0.76 - not released
866 - the align_string() method would ignore a string of "0" due to a
868 Thanks to Maurice Height for reporting this.
869 https://rt.cpan.org/Ticket/Display.html?id=60199
871 Imager 0.75_03 - 09 Aug 2010
876 - read_types() and write_types() would include png when it wasn't
877 available due to a problem with the %formats tie
879 - handle dependent libraries correctly (eg -lpng requiring -lz) in
880 the code run phase of library probing.
882 Imager 0.75_02 - 07 Aug 2010
887 - add file missing from MANIFEST, which was causing TIFF failures.
889 Imager 0.75_01 - 06 Aug 2010
892 Test release for the new PNG probe.
894 - added the ability to read multiple-image PNM files.
895 Note that unlike the pbm/pgm/ppm specification this accepts mixed
896 format files and allows white space padding between files.
897 Thanks to Philip Gwyn (Leolo) for this patch.
899 - moved the PNG file handling code into a sub-module in preparation
900 for separate distribution.
901 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
902 Also helps avoid complications from -I/-L compile/link options from
907 - Imager->new(data => $data) didn't try to process image file data in
909 https://rt.cpan.org/Ticket/Display.html?id=58761
911 - t/t50basicoo.t no longer depends on the other tests to generate its
913 https://rt.cpan.org/Ticket/Display.html?id=9798
914 Also, it wasn't testing pnm (pnm vs ppm mix-up)
916 - update the documentation of hardinvert to match the change in 0.62.
917 https://rt.cpan.org/Ticket/Display.html?id=59785
919 - added hardinvertall filter which also inverts the alpha channel
922 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
923 the probe can find the library for the test run.
924 https://rt.cpan.org/Ticket/Display.html?id=57518
926 Imager 0.75 - 20 Jun 2010
929 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
934 - an opacity fill based on a fountain fill would segfault when
935 filling an 8-bit/sample image.
937 - merge thickline branch polygon fix
938 https://rt.cpan.org/Ticket/Display.html?id=43518
940 Imager 0.74 - 7 May 2010
945 - read_multi() didn't handle a missing file format library correctly,
946 aborting on failing to call i_readgif_multi_wiol() or
947 i_readtiff_multi_wiol().
949 - fix spelling errors patched by Debian
950 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
952 - add an (unshipped) author test to spellcheck Imager's POD.
954 - update the TIFF file format documentation
955 https://rt.cpan.org/Ticket/Display.html?id=56510
957 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
959 Imager 0.73 - 15 Mar 2010
962 - implement outline circles, both anti-aliased and not
963 https://rt.cpan.org/Ticket/Display.html?id=19755
965 - a combine => "none" fill to a 1 or 3 channel image would produce
966 the incorrect colour.
968 Imager 0.72 - 09 Dec 2009
971 Bump version for release, since 0.71_03 is stable with CPAN testers.
973 Imager 0.71_03 - 5 Dec 2009
976 - further adjust the threads test so it only performs the tests on
977 perls where it's expected to work, and only if the threads module
980 Imager 0.71_02 - 1 Dec 2009
983 - adjust the way we load the threads module for the threads test so
984 it works with non-threaded perls
986 Imager 0.71_01 - 30 Nov 2009
991 - use scanline oriented operations to flip images instead of pixel
993 https://rt.cpan.org/Ticket/Display.html?id=39278
995 - use double/sample operations to flip large sample images instead of
996 8-bit sample operations.
997 https://rt.cpan.org/Ticket/Display.html?id=39280
1000 https://rt.cpan.org/Ticket/Display.html?id=51874
1002 - prevent double-frees when someone creates Imager objects and then
1003 creates a thread. Note: this just handles some simple cases,
1004 Imager doesn't support perl threads, and isn't likely to.
1005 https://rt.cpan.org/Ticket/Display.html?id=52268
1007 Imager 0.71 - 16 Nov 2009
1010 - add the opacity fill type - an adaptor that modifies the opacity of
1015 - the conv filter now enforces that the sum of the coefficients is
1016 non-zero. Also, rather than skipping pixels off the edge off the
1017 edge of the image, the closest edge pixel is used. Previously
1018 dividing by the zero sum of coefficients could cause invalid
1019 results or runtime exceptions.
1020 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
1023 Imager 0.70 - 21 Sep 2009
1028 - release image row and comments memory on all error returns in gif
1031 - handle zero length extensions, previously this would cause a null
1033 Thanks to Krzysztof Wojtaś for the test data and fix for this.
1035 - an integer division meant that preview scaling to below 1 pixel
1036 wide or high (which isn't too useful anyway) was calculating using
1037 NaNs on most platforms, and causing an exception on others.
1038 Thanks to David Cantrell for producing a backtrace of the crash on
1039 his Alpha-NetBSD CPAN test box which made it possible to track this
1042 Imager 0.69 - 08 Sep 2009
1047 - broken test fix - was attempting to call a function skip_all, when
1048 that should be a parameter to plan().
1050 - briefly document apidocs.perl, the tool used to build
1051 Imager::APIRef and make some minor enhancements
1053 - various minor documentation enhancements and fixes.
1055 Imager 0.68 - 07 Sep 2009
1058 - Imager->new(file => $filename) and other similar incantations will
1059 load the given file.
1060 https://rt.cpan.org/Ticket/Display.html?id=48261
1064 - avoid using CHECK as a label in Imager::Test
1065 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
1067 - re-work most image file test files that require a library into
1068 separate library present/not present files to remove stupidly long
1071 - don't treat rubthrough() outside the bounds of the target image as
1073 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
1075 Imager 0.67_01 - 02 Sep 2009
1080 - correct documentation of default of raw image interleave read
1082 https://rt.cpan.org/Ticket/Display.html?id=42074
1084 - add raw_ prefix to raw read parameters, though the original names
1087 - fail the read if an invalid raw_interleave parameter is supplied
1089 - warn if no interleave or raw_interleave parameter is supplied,
1090 since the documented default was wrong, and incompatible with the
1093 - for reading raw images, if raw_storechannels > raw_datachannels,
1094 set the extra channels in the image to 0
1096 - when probing for executables like freetype-config, search for .bat
1097 and .cmd on MSWin32, as well as .exe.
1098 https://rt.cpan.org/Ticket/Display.html?id=49275
1100 - re-work the external libraries section of README:
1101 - list Debian and Redhat package names for each library
1105 - use the new EU::MM META_MERGE facility instead of generating
1106 META.yml from scratch
1107 https://rt.cpan.org/Ticket/Display.html?id=47888
1109 - use Devel::CheckLib (bundled, modified) to check which release of
1110 libtiff is installed and reject 3.9.0
1111 http://bugzilla.maptools.org/show_bug.cgi?id=2088
1112 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
1114 Imager 0.67 - 12 Dec 2008
1119 - fix a packaging error
1121 Imager 0.66 - 12 Dec 2008
1124 - 24-bit color .ICO/.CUR files can now be read.
1128 - an optimization skipping 0 src alpha values could cause the
1129 rubthrough() to read past the end of a buffer.
1130 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
1132 - corrected a reference leak where writing GIFs would leak memory.
1133 This could also happen calling to_paletted().
1134 Also documented the underlying long existing feature where the
1135 colors parameter is filled with the generated color table and added
1137 http://rt.cpan.org/Ticket/Display.html?id=41028
1139 - write out the image size in bytes field of a BMP correctly.
1140 http://rt.cpan.org/Ticket/Display.html?id=41406
1142 - add limited tests for Imager::ExtUtils
1144 - make Imager::ExtUtils->includes use an absolute path, since
1145 a relative path could cause failures using Inline::C.
1146 http://rt.cpan.org/Ticket/Display.html?id=37353
1148 - re-arrange the POD for Imager::Font::BBox:
1149 - mark total_width(), pos_width(), end_offset() obsolete, since
1150 they're mostly for backwards compatibility
1151 - group width methods and height methods
1152 https://rt.cpan.org/Ticket/Display.html?id=39999
1154 Imager 0.65 - 20 May 2008
1159 - In some cases when an error occurs reading those parts of a JPEG
1160 file after the image the scan-line buffer could be freed a second
1161 time. In cases where the the error occured while reading the image
1162 data it's possible that the buffer could have leaked.
1163 Thanks to Gabriel Vasseur for reporting this and help in tracking
1166 - the gif_screen_height tag was overriding the screen width and being
1167 ignored for the screen height when present.
1168 https://rt.cpan.org/Public/Bug/Display.html?id=35568
1170 Imager 0.64 - 23 April 2008
1173 This is a bug fix release. This includes a fix for a possible
1178 - Possible security issue: The floating point sample path for image
1179 based fills had a buffer overflow. This would overwrite the end of
1180 a malloc()ed buffer with double precision floats.
1181 http://rt.cpan.org/Ticket/Display.html?id=35324
1184 - check that the result of fileno($fh) is defined rather than simply
1185 true when read() or write() is supplied with an fh parameter.
1186 http://rt.cpan.org/Ticket/Display.html?id=35139
1188 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1189 resulting in a SIGSEGV when attempting to scale an image to a size
1190 too large to fit in memory. This is a NULL pointer access issue,
1191 not a buffer overflow.
1192 Added a check for the failure.
1193 scale_calculate() (and hence scale()) will now fail if any of the
1194 scale size parameters are a reference.
1195 http://rt.cpan.org/Ticket/Display.html?id=35172
1197 - Regression: filling a greyscale image with a hatch used the wrong
1198 color channels from the supplied fg/bg colors.
1199 https://rt.cpan.org/Ticket/Display.html?id=35278
1201 - fixed a related problem for image fills.
1203 Imager 0.63 - 7 April 2008
1206 This release primarily contains changes to improve ease of use -
1207 rather than you having to convert images to the appropriate number of
1208 channels, Imager handles it internally. How to handle drawing colors
1209 and the default combine mode is a thornier problem left for some other
1212 - the font libraries are now only initialized when needed.
1213 http://rt.cpan.org/Ticket/Display.html?id=28825
1215 - moved the imtoc.perl code into Imager::Preprocess
1217 - paste() and rubthrough() now adapt the source image data to the
1218 destination, so you can now safely paste/rubthrough from greyscale
1219 images to color images or back, or from alpha channel images to
1220 noalpha channels or back.
1221 https://rt.cpan.org/Ticket/Display.html?id=30908
1223 - rubthrough() now falls back to pasting when the source doesn't have
1224 an alpha channel. This effectively treats the source as having a
1225 max alpha channel, the right thing to do.
1226 http://rt.cpan.org/Ticket/Display.html?id=29944
1228 - re-worked most of the area filling code to use a common set of
1229 functions when filling.
1230 Corrected normal combine mode.
1231 Rewrote most of the combine modes to match the way the SVG draft
1232 defines them with respect to a translucent source and destination.
1233 Added tests for translucent source and destination.
1234 Added tests to check 8-bit/sample and double/sample combines work
1236 https://rt.cpan.org/Ticket/Display.html?id=29879
1238 - writing a 2 or 4 channel image to a JPEG file will now write that
1239 image as if composited against a background, black by default,
1240 overridable with the i_background tag/parameter.
1241 https://rt.cpan.org/Ticket/Display.html?id=29876
1243 - writing a 2 or 4 channel image to a PGM/PPM file will now write
1244 that image as if composited against a background, black by default,
1245 overridable with the i_background tag/parameter.
1246 http://rt.cpan.org/Ticket/Display.html?id=30074
1248 - writing a 2 or 4 channel image to a BMP file will now write that
1249 image as if composited against a background, black by default,
1250 overridable with the i_background tag/parameter.
1251 http://rt.cpan.org/Ticket/Display.html?id=30075
1255 - Imager::Matrix2d->translate() now only requires one of the x or y
1257 http://rt.cpan.org/Ticket/Display.html?id=29937
1259 - mixing qtype scaling now sets all channels of a pixel to zero if
1260 the pixel has zero coverage (zero alpha). This should produce more
1261 compressible output files.
1262 http://rt.cpan.org/Ticket/Display.html?id=32324
1264 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
1266 https://bugzilla.redhat.com/show_bug.cgi?id=166254
1267 I'm not changing the #! lines of the sample code, since it's sample
1268 code, not intended for installation.
1269 http://rt.cpan.org/Ticket/Display.html?id=33408
1271 - some TGA images weren't being detected correctly as TGA images
1272 https://rt.cpan.org/Ticket/Display.html?id=32925
1274 - handling of the left-over bit for 16-bit/pixel TGA images has been
1275 changed to match the behaviour of the GIMP. Previously the bit
1276 being set was treated as an opaque pixel, but one user reported a
1277 problem with loading such an image. I haven't been able to find any
1278 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1279 I'll match it's behaviour. See issue 114913 in the GIMP's
1281 http://rt.cpan.org/Ticket/Display.html?id=32926
1283 Imager 0.62 - 10 December 2007
1286 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
1287 to /path under your home directory.
1288 http://rt.cpan.org/Ticket/Display.html?id=29484
1290 - the old dynaload code used Mach API functions to load dynamic
1291 libraries on Mac OS X. These APIs have been deprecated in OS X
1292 10.5 and were causing some build problems.
1293 So henceforth Imager uses the dlopen() family of functions, and you
1294 will need version 10.3 or later of OS X.
1296 - added the det() function to the transform2() engine.
1297 added the sample quad_to_square.pl
1298 Courtesy Richard Fairhurst.
1299 http://rt.cpan.org/Ticket/Display.html?id=31244
1303 - samples/gifscale.pl sourced the base value for gif_top from
1305 Thanks to Eleneldil G. Arilou for pointing this out.
1307 - t/t82inline.t no longer loads B at runtime, to work around a bug
1308 in some 5.005_0[45] installations.
1309 http://rt.cpan.org/Ticket/Display.html?id=30508
1311 - work around Module::Depends::Intrusive bug #21229
1312 http://rt.cpan.org/Ticket/Display.html?id=30520
1314 - the hardinvert filter no-longer inverts the alpha channel.
1315 http://rt.cpan.org/Ticket/Display.html?id=30002
1317 - the hardinvert filter now supports large samples
1319 Imager 0.61_02 - 28 November 2007
1322 - major TIFF support re-work
1323 http://rt.cpan.org/Ticket/Display.html?id=20329
1325 - added a C level image interface for accessing samples from 1-32
1326 bits, exposed this at the perl level in getsamples()
1328 - the conv filter now works at floating point precision for high bit
1331 - added is_bilevel method to test whether an image should be written as
1332 a bilevel image if the image format supports it.
1334 - added -log-stderr as an Imager import list option
1336 - added some important types to Imager::APIRef
1338 - added test_image_double() to Imager::Test
1342 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
1345 - the scale() method with qtype mixing now handles images with an
1346 alpha channel correctly.
1348 - fixed a broken link from the "animated GIF" entry in the concept index.
1349 Thanks to Slaven Rezic.
1350 http://rt.cpan.org/Ticket/Display.html?id=30889
1352 - on some perl's the infix expression parser test would fail due to
1353 actions in the grammar returning false. Made sure all actions return
1355 Thanks to Richard Fairhurst for spending a lot of time in tracking
1357 http://rt.cpan.org/Public/Bug/Display.html?id=29562
1359 Imager 0.61 - 5 November 2007
1362 - added samples/gifscale.pl, which adjusts the screen size/position tags
1363 when scaling an animated gif
1364 http://rt.cpan.org/Ticket/Display.html?id=27591
1368 - correct handling of sz in matrix_transform() - this should allow
1369 perspective type transformations to work now.
1370 http://rt.cpan.org/Ticket/Display.html?id=29936
1372 - prevent a cast to integer warning on x64 builds in datatypes.c
1373 also fixed some other type warnings
1374 https://rt.cpan.org/Ticket/Display.html?id=30204
1376 - some sub-directory tests depended on files produced by the parent
1378 http://rt.cpan.org/Ticket/Display.html?id=30203
1380 - Imager::Font::Wrap doesn't correctly set savepos
1381 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
1382 http://rt.cpan.org/Ticket/Display.html?id=29771
1384 - test 171 in t/t01introvert.t was failing on perls configured to
1386 http://rt.cpan.org/Ticket/Display.html?id=29413
1388 - the code for the transform2() uminus operator was missing a break.
1389 Added tests for better code coverage of the ops.
1390 http://rt.cpan.org/Ticket/Display.html?id=29296
1392 - the SGI RLE compression code could overflow its compression buffer
1393 http://rt.cpan.org/Ticket/Display.html?id=30334
1395 - the 32-bit output function used by the SGI code only handled values
1396 under 0x10000. This was most noticable when writing large RLE images.
1397 http://rt.cpan.org/Ticket/Display.html?id=30335
1399 - validate chan_count for chans == NULL for each of the i_gsamp()
1401 http://rt.cpan.org/Ticket/Display.html?id=28985
1403 - attempt to work around the test failure at
1404 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
1405 http://rt.cpan.org/Ticket/Display.html?id=29562
1407 - improve the error messages produced when attempting to read or write
1408 an unknown image file format.
1409 http://rt.cpan.org/Ticket/Display.html?id=30103
1411 - improve the transform2() documentation
1412 http://rt.cpan.org/Ticket/Display.html?id=29267
1414 - correctly generate the author key in META.yml
1415 http://rt.cpan.org/Ticket/Display.html?id=30377
1417 - correctly blend a rotated (or matrix_transformed()) image when
1418 performing interpolation in the presence of an alpha channel.
1419 Also corrected the centring of the rotated image on the output
1422 Imager 0.60 - 30 August 2007
1425 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
1426 now has full SGI RGB image format, including RLE and 16-bit/sample
1428 https://rt.cpan.org/Ticket/Display.html?id=8666
1430 - logging functions are now available in the API
1432 - applied Gabriel Vasseur's patch
1433 added documentation, further tests, and support for greyscale images
1434 Obviously problems are my fault :)
1435 https://rt.cpan.org/Ticket/Display.html?id=28142
1437 - the mask for ICO/CUR images is now applied as an alpha channel to
1438 the returned image. For the old behaviour, supply ico_masked => 0
1439 to read() or read_multi(). This should be less confusing when
1440 using Imager as a general image processor.
1441 https://rt.cpan.org/Ticket/Display.html?id=29001
1445 - in some cases it's possible for giflib/libungif to return color
1446 indexes outside the range of colors defined by the image's palette.
1447 We now expand the palette to match the indexes used.
1448 Thanks to Gabriel Vasseur for reporting this.
1450 - fixed various memory leaks that could occur when failing to read png,
1451 jpeg, bmp or tga files.
1453 - to avoid confusion, channels not present in the image are returned as
1454 zero by getscanline(). This has no effect on the C level i_glin()
1455 and i_glinf() API functions which continue to not set the unused
1458 - the convert() method now returns an image of the same sample size as
1460 https://rt.cpan.org/Ticket/Display.html?id=28492
1462 - remove repeated text in Imager::Files
1463 http://rt.cpan.org/Ticket/Display.html?id=27589
1465 - be even more explicit that scale() and friends don't modify the source
1466 image, but return a new image.
1467 http://rt.cpan.org/Ticket/Display.html?id=28570
1469 - improve the error message from errstr() when you try to load a font
1470 for which the driver hasn't been built in Imager.
1471 http://rt.cpan.org/Ticket/Display.html?id=27571
1473 - transparency is now enabled by default when writing GIF images
1474 http://rt.cpan.org/Ticket/Display.html?id=27615
1476 - Imager would not load on Windows 98
1477 http://rt.cpan.org/Ticket/Display.html?id=27653
1479 Imager 0.59 - 14 June 2007
1484 - fixes a regression introduced by the fixes for RT 11972
1485 http://rt.cpan.org/Ticket/Display.html?id=27546
1487 - cropping outside the image would return an Imager object with
1488 no low-level image object, instead of returning false.
1489 Fixed by: Philip Gwyn (Leolo)
1490 http://rt.cpan.org/Ticket/Display.html?id=27509
1492 Imager 0.58 - 16 May 2007
1495 No significant changes from 0.57_01.
1497 Imager 0.57_01 - 11 May 2007
1500 - added to_rgb16 to produce a 16-bit/sample version of an image
1502 - improve freetype 1.x text output efficiency
1506 - search another place for rgb.txt, and check all the places
1507 Imager::Color checks when deciding whether to skip testing it
1508 http://rt.cpan.org/Ticket/Display.html?id=26064
1510 - use a convolution kernel size based on the stddev rather than a
1511 fixed size when performing a gaussian blur
1512 http://rt.cpan.org/Ticket/Display.html?id=25645
1514 - document the difference() method's mindist parameter, and debug it.
1516 - put the Imager release number in the Inline::C generated code to
1517 regenerate Inline code when a new release of Imager is installed.
1518 http://rt.cpan.org/Ticket/Display.html?id=26278
1520 - fix rendering on alpha channel images for the FreeType 1.x driver.
1521 http://rt.cpan.org/Ticket/Display.html?id=11972
1523 - fix rendering on alpha channel images for the T1lib driver.
1524 http://rt.cpan.org/Ticket/Display.html?id=11972
1526 - reworked library probing, we can now set more than one probe
1527 function for a library. Disabled the default (non-freetype-config)
1528 library probe and added an extra probe function that searches for
1529 both ft2build.h and whatever it includes, and adds -I as needed.
1530 Hopefully this will fix build problems like
1531 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
1532 http://rt.cpan.org/Ticket/Display.html?id=26086
1534 Imager 0.57 - 30 Apr 2007
1537 This is a maintenence release fixing a security issue in Imager.
1539 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
1540 overflow in malloced memory. There will be further discussion of
1541 this issue in the ticket below.
1542 http://rt.cpan.org/Ticket/Display.html?id=26811
1543 CVE-2007-2459 CVE-2007-2413
1544 The descriptions at cve.mitre.org varied in quality, please see the
1545 ticket at rt.cpan.org for a more accurate description of the issue.
1547 Imager 0.56 - 1 Apr 2007
1550 - added support for reading 16-bit/sample PGM/PPM images
1552 - added support for writing 16-bit/sample PGM/PPM images
1554 - improved performance of reading PBM/PGM/PPM images
1556 - added support for writing PBM images if the image is paletted and
1557 contains only black and white
1559 - added a new make_colors value - "mono"
1561 - switched from the svn log Changes to a manual Changes to reduce
1564 - new sample code - samples/flasher.pl
1568 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
1569 was returning an image object with an extra reference, this
1570 resulted in a memory leak.
1571 http://rt.cpan.org/Ticket/Display.html?id=24992
1573 - fix rendering on alpha channel images for the FreeType 2.x driver
1574 http://rt.cpan.org/Ticket/Display.html?id=11972
1576 - reading bmp files now consitently handles short reads. You can now
1577 supply a parameter to treat a short read as successful and set
1579 http://rt.cpan.org/Ticket/Display.html?id=8426
1581 - previously, reading ASCII PBM files required spaces between samples,
1582 even though the format doesn't require that
1584 - improved documentation of the unsharpmask filter (I hope)
1585 http://rt.cpan.org/Ticket/Display.html?id=25531
1587 - force flushing of the output from i_tt_dump_names() and test output
1588 in t/t35ttfont.t to prevent output from being mixed up.
1589 https://rt.cpan.org/Ticket/Display.html?id=24859
1591 - rewrite a conditional expression as an if() to hopefully work around
1592 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
1593 https://rt.cpan.org/Ticket/Display.html?id=25561
1595 - avoid Data::Dumper in regops.perl to support older releases of perl
1596 https://rt.cpan.org/Ticket/Display.html?id=24391
1598 Imager 0.55 - 16 Dec 2006
1601 This is primarily a bug fix release.
1603 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1605 There is one new feature:
1607 - the Win32 font driver now supports UTF8 (RT 22166)
1608 http://www.cpanforum.com/threads/3276
1609 http://rt.cpan.org/Ticket/Display.html?id=22166
1611 Several bugs were fixed:
1613 - the string() method would not output the string "0"
1614 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1616 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1617 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1619 - the gif_disposal and gif_user_input tags weren't being read from
1621 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1623 - gif.c was failing to build under MSVC
1624 http://rt.cpan.org/Ticket/Display.html?id=23922
1626 - in some cases strings passed to the string() method were treated as
1627 terminated by NUL (chr 0)
1628 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1630 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1631 that's the default build name for zlib on Win32.
1632 http://rt.cpan.org/Ticket/Display.html?id=23064
1634 - search $Config{incpath} for headers too, which we should have been
1637 Win32 font driver fixes:
1639 - the global descent value from bounding box was the wrong sign
1640 http://www.cpanforum.com/threads/3276
1642 - if the first or last glyph overflowed the left or right side of the
1643 advance width they would be clipped
1646 Imager 0.54 - 14 Sep 2006
1649 This is primarily a feature release:
1651 - a new qtype value 'mixing' has been added to the scale()
1652 method. This is faster than 'normal', slower than 'preview'. This
1653 is based on the method used by pnmscale, and seems to produce less
1654 blurry results than normal.
1655 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1657 - the rubthrough() method can now render onto images with an alpha
1659 http://rt.cpan.org/Ticket/Display.html?id=20678
1661 - the read_multi() method now falls back to calling doing a single
1662 image read via the read() method and write_multi() will now fall
1663 back to calling write() if a single image is supplied. This means
1664 you can simply call the read_multi() or write_multi() functions
1665 without having to check if the type is formatted by that method.
1666 http://rt.cpan.org/Ticket/Display.html?id=19457
1667 http://rt.cpan.org/Ticket/Display.html?id=19458
1669 - the GIF loop extension can now be written. If you don't have
1670 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1672 http://rt.cpan.org/Ticket/Display.html?id=21185
1674 - getscanline() and setscanline() can now read/write palette index
1675 based data from/to the image for paletted images, by setting type to
1677 http://rt.cpan.org/Ticket/Display.html?id=20338
1679 - we no longer hassle you to disable GIF support
1680 http://rt.cpan.org/Ticket/Display.html?id=20687
1682 - minor documentation fixes
1685 Imager 0.53 - 26 Jul 2006
1688 This is a bugfix release.
1690 Some test code was left in a code path not covered by the test
1691 suite. A test was added to cover this code path and the test code was
1693 http://rt.cpan.org/Public/Bug/Display.html?id=20705
1696 Imager 0.52 - 25 Jul 2006
1699 This is primarily a feature release, but contains a fair few bug
1700 fixes, new features:
1702 - ability to read and write MS Windows ICO and CUR files
1704 - you can now add file format plugins to support new file formats
1706 - add POD coverage tests
1708 - setcolors() and addcolors() now accept color names and so on
1709 instead of requiring Imager::Color objects.
1710 http://rt.cpan.org/Ticket/Display.html?id=20056
1712 - flood_fill() can now fill to a specified border color instead of
1713 just to the area the same color as the seed.
1714 http://rt.cpan.org/Ticket/Display.html?id=19618
1719 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1720 calculating the advance width.
1721 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1723 - bounding_box for the T1 driver wasn't including leading and
1724 trailing spaces in the bounding box as the other drivers did, it also
1725 produced strange results for empty strings or strings containing only
1728 - when reading CMYK jpeg images they were being transferred to the
1729 image object as is, producing a four channel image. It only looked ok
1730 due to an old still unfixed Photoshop bug. We now convert from the
1731 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1732 http://rt.cpan.org/Ticket/Display.html?id=20416
1734 - reading a CYMK TIFF would result in a 4 channel image, reading any
1735 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1737 http://rt.cpan.org/Ticket/Display.html?id=20415
1739 - added /usr/local/include to the default include search path, since
1740 we were already searching /usr/local/lib for libraries.
1742 And various minor fixes and documentation updates.
1745 Imager 0.51 - 23 Apr 2006
1748 - fix a validation bug when processing JPEG EXIF data that can cause
1750 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1752 - fix mis-processing of the src_maxx and src_maxy parameters of the
1754 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1756 - fix a problem in Imager's "smart" handling of the color parameter
1758 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1761 Imager 0.50 - 29 Mar 2006
1764 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1765 or 4 channel image to jpeg or a 2 channel image to tga where the
1766 output is an in-memeory buffer.
1767 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1769 - fixes an incorrect pointer parameter in the PNG code
1770 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1772 - skip Inline::C tests when building in a directory with spaces
1773 http://rt.cpan.org/Public/Bug/Display.html?id=18049
