1 Imager release history. Older releases can be found in Changes.old
3 Imager 1.011 - 7 Mar 2019
8 - correct the type of the data parameter for im_decode_exif().
10 - fix the release date listed below for 1.010
12 - add missing change entry for RT #128142
14 - binmode the correct handle in t/200-file/010-iolayer.t, this may fix some test
15 failures on one CPAN smoker.
17 - add the mymeta check (AUTHOR testing only) to MANIFEST
21 - translate_errdiff() could leak memory on failure (introduced in
24 - i_img_make_palette() could leak memory on failure (introduced in
27 - DSO_open(), from the original dynamic loading API, could leak
28 dlopen() handles on failure. CID 185309. DSO_close() now releases
29 the memory associated with the internal DSO handle, rather than
30 only releasing the dlopen() handle.
32 Imager 1.010 - 13 Feb 2019
37 - added the add_file_magic() class method for adding magic for new
38 file types to Imager's fairly primitive file magic detection.
40 - fixed an embarassing documentation typo in Imager::Test.
42 - trying to read from a GIF file with no images now sets an error
43 message. Thanks to Peter Sergeant for reporting this.
44 https://rt.cpan.org/Ticket/Display.html?id=128481
46 - use undeprecated encoding symbols for FT2. This should fix the
47 build on the badly patched CentOS 7 Freetype 2. Thanks to Slaven
49 https://rt.cpan.org/Ticket/Display.html?id=128142
51 Coverity has come back up read-only, a few more changes:
53 - add missing va_end() for bmp.c's write_packed(). CID 185320.
55 - similarly for read_packed(). CID 185329.
57 - add a NOTREACHED lint comment for pixel_coverage(). Compilers
58 complained about a missing return, Coverity complains about the
61 - avoid a possible sign extension in imsgi.c. CID 185326.
63 - add some FALLTHROUGH lint comments to i_readtga_wiol() where we
64 deliberately fall through switch cases. CID 185328.
66 - add assertions in callers to i_new_hatch_low() since Coverity
67 complained about some possible inconsistent NULL checks. CID
68 185339. I ended up rearranging this function later.
70 - remove pointless NULL checks from i_flipxy() and i_img_destroy().
73 Imager 1.009 - 11 Jan 2019
78 - drawing a filled, anti-aliased circle to the left or right of the
79 image (not within the image at all) would cause a buffer overflow.
80 https://rt.cpan.org/Ticket/Display.html?id=128208
84 - to_paletted() and make_palette() now fail (with an error in
85 errstr()) if invalid quantization parameters are supplied.
87 - map() would corrupt a channel if there was a gap in the arrayref of
88 channels. Detected by Coverity. CID 185300.
90 - most numeric parameters to the XS implementation now throw an
91 exception if supplied an unoverloaded reference.
92 https://rt.cpan.org/Ticket/Display.html?id=128208
94 Coverity finally finished a build[1], fixed several of the problems
95 found. Coverity went down before I could finish working through them.
99 - reading a color-mapped TGA file with an id string would cause a
100 double-free if the palette was truncated. CID 185317.
102 - mixing scaling to sizes where the accumulator row, the working
103 output row or the working input row didn't fit into the address
104 space could result in memory leaks. This can probably only be
105 reproduced on very wide floating-point sample images. CID 185318.
107 - convert an array style function parameter pointer to pointer style
108 to prevent confusing Coverity in the T1 bounding box implementation.
111 - Similarly in the FT1 bounding box implementation. CID 185338.
113 - Similarly for the i_tt_rasterize() function in the FT1
114 implementation. CID 185303.
116 - initialize a pointer to prevent Coverity complaining in polygon
117 drawing (it should always end up being set.) CID 185341.
119 - addi style makemap could potentially read one past the end of an
122 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
123 would result in read beyond the end of the built-in hatch array.
124 Negative values (which Coverity didn't complain about) could also
125 cause problems. CID 185331.
127 - the Imager::Color set_internal() interal method no longer
128 calls the over-complicated ICL_set_internal() (which is retained
129 only for the old API.) Coverity complained that this leaked, but
130 this could only occur with an invalid (NULL pointer) color object.
133 - the underlying implementation of the map() method could read before
134 the beginning on an allocated array if supplied with inconsistent
135 parameters, which Coverity complained about. No Imager code calls
136 that function with inconsistent parameters, but a
137 belt-and-suspenders check was added. CID 185315.
139 - Coverity complained a call to i_getcolors(), used by the
140 implementation of the is_bilevel() method could leave the fetched
141 colors uninitialized. Added a return value check. CID 185308.
143 - a numeric combining mode of 13 (eg. as a parameter to
144 Imager::Fill->new())could cause an invalid array read in
145 i_get_combine() due to a fencepost error in validating the combine
148 Lower severity (according to Coverity):
150 - avoid an unneeded EXTEND() call when the FT1 has_chars()
151 implementation returns 0. CID 185350.
153 - avoid accessing a possibly NULL map from MakeMapObject() in a
154 logging call. (GIF) CID 185296.
156 - gradgen() allocated the wrong amount of space (always too much) for
157 the color array. CID 185291.
159 - avoid dead code in i_tt_glyph_names(). CID 185321.
161 - avoid dead code in i_get_anonymous_color_histo(), which is the
162 implementation of getcolorusage(). CID 185327.
164 - avoid dead code in i_ft2_glyph_name(), which is the implementation
165 of glyph_names() for FT2. CID 185342.
167 - avoid dead code in i_t1_glyph_names(), which is the implementation
168 of glyph_names() for T1. CID 185322.
170 - avoid an unneeded EXTEND() call when the FT2 has_chars()
171 implementation returns 0. CID 185292.
173 - the unpack code for ICO/CUR file handling could extend 32-bit
174 unsigned values to 64-bit signed. I believe this is harmless. CID
177 - remove an unneeded check when terminating the stream for JPEG
180 - skip an unneeded check when freeing the combine temp buffer in the
181 fountain filter. CID 185286.
183 - check the combine function pointer consistently rather than the
184 combine code in one place in the fountain filter.
186 - error diffusion now validates a custom error diffusion map and reports
187 an error if it's bad. CID 185288.
189 - avoid discarding the value of i_io_getc() when scanning numbers in
192 - handle failure to clone the log filehandle when cloning the Imager
193 context object on thread creation. CID 185294.
195 - fix an unsigned comparison when converting character code to a
196 glyph index with a NULL character map when calculating the glyph
197 for display for FT1. This should be rare. CID 185297.
199 - fix a similar bug when calculating whether a glyph is present for
200 has_chars() for FT1. CID 185302.
202 - i_img_info() (C API) no longer tries to handle a NULL image object
205 - re-work testing for size_t overflow for circle/random
206 super-sampling for fountain fills. CID 185304.
208 - don't check if the unsigned size passed to Imager's malloc wrapper
209 (mymalloc) is negative. Left from when that parameter was signed.
212 - make some types larger and add a cast to prevent integer overflows
213 when calculating a palette with median cut for extraordinarily
214 large images. CID 185306.
216 - don't check if the unsigned size supplied to
217 im_set_image_file_limits() is negative. CID 185307.
219 [1] The first two build submissions ended up at the end of a ~400 item
220 build queue, and seemed to have been cancelled by Coverity. A build
221 submitted on NYE went through in minutes.
223 Imager 1.008 - 31 Dec 2018
226 - moved EXIF handling from Imager::File::JPEG to core Imager
227 This allows file formats that store EXIF data as blobs similarly
228 to JPEG to re-use this code. (such as Imager::File::WEBP)
230 - added some more file extensions to image file type mappings
232 - added add_type_extensions() class method
234 - Imager::Files now links to Imager::Install when discussing
235 appropriate libraries.
236 https://rt.cpan.org/Ticket/Display.html?id=127575
238 Imager 1.007 - 24 Nov 2018
241 - add png_compression_level tag for writing PNG files.
243 - avoid flooring a second time in matrix transform interpolation.
244 https://rt.cpan.org/Ticket/Display.html?id=124001
246 - produce v2 metadata.
247 Includes change from the ticket and updates to sub-modules.
248 https://rt.cpan.org/Ticket/Display.html?id=127216
250 - improve error reporting for the polygon() method
252 Imager 1.006 - 26 Aug 2017
255 - the internal i_errors() function now correctly allocates the stack
256 space needed for its result.
257 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
259 - t/100-base/020-color.t now uses Imager::Test's test functions
261 https://rt.cpan.org/Ticket/Display.html?id=111993
263 - write_multi() now returns an error result (a false value) if called
264 with a non-(Imager image object). Previously it would typically
266 https://rt.cpan.org/Ticket/Display.html?id=117878
268 - improve the documentation of the jpegquality parameter when
271 - add code to mitigate CVE-2016-1238, Imager will no longer search the
272 default current directory entry in @INC when searching for file
273 format support modules.
275 Imager 1.005 - 16 Apr 2016
278 It's now been ten years since I switched to the new Changes file in
281 - revert the ivdformat probes, they don't work as is and trying to
282 fix them is too much work for now.
284 Imager 1.004_004 - 15 Apr 2016
287 - test that the ivdformat from Config is correct and look for a valid
289 For the strange Win32 failures.
291 - fix a copy and paste error in pod in samples/samp-form.cgi
293 Imager 1.004_003 - 23 Mar 2016
296 - add some extra error reporting to the I/O layers tests, this might
297 help catch a failure seen on Win32.
298 http://cpantesters.org/cpan/report/99781689-6bf5-1014-897a-75cb4eee1325
300 Imager 1.004_002 - 20 Mar 2016
303 - don't use the seek() method on opened() handles in
304 t/200-file/400-basic.t. In older versions of perl such handles are
305 only IO::Handle objects, not IO::File, and don't have a seek()
308 Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
311 - re-work the t/200-file/400-basic.t to correctly handle failures
312 It's custom ok() function didn't have a prototype and didn't use scalar().
313 This caused ok() to use the note instead of the value being tested when
314 the method called returned an empty list. For an example of the problem
315 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
317 - remove some noise from when Imager tried to work with bugs in old
318 versions of giflib. I can't do much about the new bugs.
320 - the new autolevels filter (Imager 0.99) used an integer for the
321 sample scaling factor which caused the top output level to be too
322 low (depending on the scaling required.) It now uses a double.
323 https://rt.cpan.org/Ticket/Display.html?id=111871
325 - the new autolevels filter had off-by-one errors calculating the
326 minimum and maximum luminance from the histogram. This slightly
327 reduced the contrast of the output image.
328 https://rt.cpan.org/Ticket/Display.html?id=111871
330 - the new autolevels filter now uses a lookup table for 8-bit images
331 to avoid a floating point multiply for each sample.
332 https://rt.cpan.org/Ticket/Display.html?id=111871
334 - fixed several memory leaks detected by valgrind:
336 - addcolors() leaked the temporary array of colors supplied to the
339 - make_palette() leaked the temporary image array (not the images
340 themselves) passed to the internal API.
342 - combine()/i_combine() leaked its working row buffers
344 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
345 buffer if there were too many colors
347 - getcolorcount()/i_count_colors() leaked the sample buffer if
348 there were too many colors.
350 - the nearest_color filter (undocumented until I find a use for it)
351 leaked both temporaries passed to the API and internal buffers
353 - the internal process of upgrading a paletted image to a direct
354 color image would leak a context object reference count.
356 - a write failure when writing to a GIF file could leak memory.
358 - failing to write to a 1-bit/pixel ICO image could leak memory.
360 - Imager no longer deliberately leaks the context object from the
361 initial thread. This was done to ensure there was always a context
362 object available, but the code that needed that now handles the
365 - fixed some uninitialized memory usage detected by valgrind:
367 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
368 i_matrix_transform_bg() didn't initialize a working color value
369 if there was zero pixel coverage.
371 - i_ft2_cp() didn't initialize the complete color when producing an
372 intermediate image. This caused uninitialized value usage when
375 Imager 1.004 - 8 Nov 2015
378 - Imager::Color::Table is now pre-loaded by the preload() method.
379 https://rt.cpan.org/Ticket/Display.html?id=104896
381 - fix an assertion triggered under perl 5.23.4.
382 Thanks to A. Sinan Unur for the report and the patch.
384 - Imager->new can now be used to read raw image files.
385 https://rt.cpan.org/Ticket/Display.html?id=106836
386 Thanks to Richard Kelsch for reporting this.
388 - deal with output changes from Pod::Spell
389 https://github.com/perl-pod/Pod-Spell/issues/21
391 Imager 1.003 - 12 May 2015
394 - update 1.002 release notes to include the center change for filled
397 - flood_fill() would escape beyond a 4-connected space under some
399 Added many more flood_fill() tests.
400 https://rt.cpan.org/Ticket/Display.html?id=103786
402 Imager 1.002 - 3 Apr 2015
405 - drawing anti-aliased filled circles is now 10 to 50 times faster
406 depending on the size of the circle.
407 This also changed the center from being the center of the pixel to
408 being the top left of the pixel to match the filled arcs drawn by
410 https://rt.cpan.org/Ticket/Display.html?id=101682
412 - enhancements to polygon filling:
414 - added a mode parameter to control how overlapping regions behave
416 - added a polypolygon() method to fill more than one polygon at a
419 - polygon filling is now exposed through the API.
421 - added colormodel(), alphachannel() and colorchannels() methods.
422 These were added for two reasons:
424 - a future version of Imager may allow the number of channels in
425 an image to not directly represent the color model of an image.
426 eg. a greyscale TIFF image with multiple alpha channels.
428 - a future version of Imager may allow an image to be read without
429 translation, for example a TIFF file that contains measurements
430 from an instrument. Currently Imager transforms the samples into
431 the range 0.0 ... 1.0 which may means the user has to translate
434 An untranslated image would be unusable as image data, so
435 colormodel() would return "unknown" in this case.
437 Similarly a CMYK image might be returned as an "unknown" color
438 model image, if the caller chooses to disable translation to
441 Imager 1.001 - 2 Jan 2015
444 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
445 Thanks to Slaven Rezic for the report and the patch.
446 https://rt.cpan.org/Public/Bug/Display.html?id=98234
448 - GIF: clean-up a test file if the test for the giflib 4.2.0 file
451 - fix Imager::Matrix2d::rotate()'s centre point handling
452 https://rt.cpan.org/Public/Bug/Display.html?id=99959
454 - ICO: don't apply the icon mask to images with an alpha channel by
456 https://rt.cpan.org/Public/Bug/Display.html?id=99507
458 - make verbose probing output more verbose
460 - use Imager::Probe to probe for freetype 1.x
461 https://rt.cpan.org/Ticket/Display.html?id=100502
463 - The --enable and --disable parameters to the top-level Makefile.PL
466 - update the bundled/modified Devel::CheckLib to handle the gcc-4
469 Imager 1.000 - 28 Jul 2014
472 There's nothing special about Imager 1.000, it's just another release.
474 - fix the skip check for the iolayer qr// buffer test
476 - improve error reporting for the iolayer test failing on a small
477 number of Win32 CPAN testers
479 Imager 0.99_02 - 21 Jul 2014
482 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
483 the blue channel in the generated palette, and allow each color
484 component to be in the range 100..255 instead of just 100..254.
485 Thanks to Ralf Neubauer.
486 https://rt.cpan.org/Ticket/Display.html?id=97086
488 - revert "improved the XS for i_io_read() and i_io_raw_read()"
489 This caused problems with older perls and didn't provide much of a
490 performance improvement.
492 - support Inline 0.57 and later.
493 Inline 0.57 changed the "with" interface.
494 https://rt.cpan.org/Ticket/Display.html?id=97108
496 - don't define our own MAXINT macro, it conflicts with windows header
497 files and in a few places it was the wrong value to use anyway.
498 https://rt.cpan.org/Ticket/Display.html?id=96425
500 Imager 0.99_01 - 29 Jun 2014
503 - GIF: add support for giflib 5.1.0, which added error code pointer
504 parameters to EGifCloseFile() and DGifCloseFile().
505 https://rt.cpan.org/Ticket/Display.html?id=96756
507 - GIF: avoid a double-free when do_write() fails.
509 - fix SV type probing to work on perl before 5.12. Broken in 0.99.
510 https://rt.cpan.org/Ticket/Display.html?id=96761
512 - PNG: skip the benign error test before libpng 1.6.0, since the
513 error we're testing didn't exist before 1.6.0.
514 https://rt.cpan.org/Ticket/Display.html?id=94717 (continued)
516 Imager 0.99 - 25 Jun 2014
519 - Imager::IO->new_buffer() (and hence Imager->read()'s data
520 parameter) now accepts a reference to a scalar as well as just a
522 https://rt.cpan.org/Ticket/Display.html?id=92785
524 - Imager::IO->new_buffer() now always makes a copy of the passed in
525 buffer to avoid problems with temporary objects used for the return
527 https://rt.cpan.org/Ticket/Display.html?id=92785
529 - improved the XS for i_io_read() and i_io_raw_read()
530 https://rt.cpan.org/Ticket/Display.html?id=92738
532 - load plugins from absolute paths on Android
533 Thanks to Brian Fraser.
534 https://rt.cpan.org/Ticket/Display.html?id=93272
536 - added the jpeg_optimize parameter for writing JPEG files. This can
537 significantly reduce file sizes, but uses more memory and time.
538 https://rt.cpan.org/Ticket/Display.html?id=94292
540 - the autolevels filter now works on the luminosity of the image
541 rather then working per channel. The old autolevels filter is
542 still available as "autolevels_skew".
543 https://rt.cpan.org/Ticket/Display.html?id=94413
545 - Imager::File::PNG now supports libpng 1.6.10.
546 1.6.10 changed CRC errors from benign errors to normal errors,
547 which broke the test which used CRC errors to check for benign
548 error support. Switched to using a 1-bit grey-scale image with a
549 palette to test for benign errors.
550 https://rt.cpan.org/Ticket/Display.html?id=94717
552 Imager 0.98 - 3 Jan 2014
555 Incompatible changes:
557 - the return value of setpixel() has changed.
559 Previously the return values for undrawable pixels vs caller errors
560 changed depending on whether you used the multiple pixel calling
561 mechanism, or the single pixel mechanism.
565 - for an invalid parameter, such as an unknown colour, or missing
566 parameter, an empty list (or undef in scalar context) is
567 returned, and errstr() is set,
569 - otherwise the number of pixels drawn is returned. If none of
570 the pixels could be drawn (they were all outside the image), "0
571 but true" is returned.
573 https://rt.cpan.org/Ticket/Display.html?id=87650
577 - when drawing on an image with an alpha channel where the source
578 minimum is greater than zero, Imager would read from beyond the end
579 of a malloc() allocated buffer. In rare circumstances this could
580 lead to some of the source image not being written to the target
581 image, or possibly to a segmentation fault.
582 I don't believe this has any security concerns beyond that.
584 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
585 text drawn would be nonsense. This would also read beyond the end
586 of a malloced buffer.
588 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
590 https://rt.cpan.org/Ticket/Display.html?id=88993
592 - Imager::Font::Wrap no longer requires the image parameter.
593 https://rt.cpan.org/Ticket/Display.html?id=87338
595 - a documentation typo fix in Imager::Transformations
596 Thanks to Adrian Yee.
597 https://rt.cpan.org/Ticket/Display.html?id=88598
599 - Image::Probe, Imager's internal module for probing library
600 locations now searches the directories specified by LD_RUN_PATH,
601 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
602 and the corresponing s/\blib$/include/ directories for header
604 https://rt.cpan.org/Ticket/Display.html?id=86428
606 Imager 0.97 - 15 Jul 2013
609 No changes from 0.96_02.
611 Imager 0.96_02 - 8 Jul 2013
614 - PNG: treat a version mismatch between headers and library as a
616 https://rt.cpan.org/Ticket/Display.html?id=86659
618 - PNG: the check for benign error support is more complex than a
619 simple library version check, check for the appropriate macro.
620 Thanks for Slaven Rezic for following up on my CPAN Testers result
622 https://rt.cpan.org/Ticket/Display.html?id=86659
624 - W32: add a missing head1 AUTHORS to the old Win32.pm
625 https://rt.cpan.org/Ticket/Display.html?id=86658
627 Imager 0.96_01 - 1 Jul 2013
630 - TIFF: handle SampleFormat = 2 by translating the signed integer
631 values to unsigned by flipping their sign bits.
633 Handle SampleFormat = 3 where possible.
635 SampleFormat is ignored for paletted images.
637 Mixed SampleFormat are handled incorrectly, since libtiff returns
638 only the first SampleFormat value, and an image with both an alpha
639 channel and SampleFormat = 2 for color channels probably has a
640 different SampleFormat for the alpha channel.
642 https://rt.cpan.org/Ticket/Display.html?id=74540
645 https://rt.cpan.org/Ticket/Display.html?id=69243
647 - Imager::Color's rgba() method now returns its values as integers
648 instead of floating point. (IV instead of NV).
650 - The XS for i_map() and i_matrix_transform() now use the AV *
651 typemap instead of rolling their own.
653 - The XS for DSO_call() now uses the HV * typemap instead of
656 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
657 i_gradgen() now use a new T_AVARRAY typemap that greatly
658 simplifies the XS code.
660 - many other minor XS changes
662 - some XS code formatting
664 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
665 now renders in alpha-combining mode, to match antialiased output.
666 https://rt.cpan.org/Ticket/Display.html?id=73359
668 - add sample code and cookbook notes for drawing a blurred drop-shadow.
670 - add support for libpng 1.6, which changed the defaults for
671 reporting some types of error.
672 https://rt.cpan.org/Ticket/Display.html?id=85746
674 - FT2: use gsamp/psamp() to transfer pixels from the work image to
675 the output image instead of gpix/ppix.
676 https://rt.cpan.org/Ticket/Display.html?id=83478
678 - eliminate various GCC warnings, mostly initialized but otherwise
681 Imager 0.96 - 19 May 2013
684 - rearrange Imager's test files.
685 https://rt.cpan.org/Ticket/Display.html?id=84596
687 - Imager::Probe::_gcc_lib_paths now forces C locale.
688 A sufficiently recent gcc prints localized keys for the search
689 paths, which avoids that localization.
690 https://rt.cpan.org/Ticket/Display.html?id=84963
692 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
693 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
695 https://rt.cpan.org/Ticket/Display.html?id=85262
696 reported by Andreas König
698 - add a test for unclosed POD in C source, and fix the errors it
700 https://rt.cpan.org/Ticket/Display.html?id=74875
702 - fix some spelling errors detected by the newer aspell in Debian
705 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
706 thanks to gregor herrmann <gregoa@debian.org>
707 https://rt.cpan.org/Ticket/Display.html?id=85413
709 - add a test for standard =head1 commands and fix the errors found
711 Imager 0.95 - 19 Apr 2013
714 - handle the SVf_UTF8 flag correctly on magic strings passed to
715 Imager::IO's write() and raw_write() methods.
716 This may misbehave in perl 5.6.x since the UTF8 flag may not be
717 visible in the main SV after SvGETMAGIC().
718 https://rt.cpan.org/Ticket/Display.html?id=83438
720 - document that bounding_box() ignores the transformation matrix
721 supplied to tranform() for fonts.
722 https://rt.cpan.org/Ticket/Display.html?id=84106
724 Imager 0.94_02 - 5 Apr 2013
727 - enable debug logging for the standard font tests
729 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
730 due to a bug in that version of perl.
732 - don't test for read() failing on a write-only handle in 5.8.x and
733 earlier, this was fixed in change 862083f7e4 in perl.
735 - report the version of Inline found during testing (an attempt to
736 diagnose some intermittent failures.)
738 Imager 0.94_01 - 2 Mar 2013
741 - NOTE: possibly backward incompatible:
742 support reading from/writing to perl filehandes that aren't raw
745 This allows Imager's I/O to honour handles with layers such as
746 gzip, scalar file handles or tied file handles.
748 This is backward incompatible in that previous Imager would simply
749 use fileno() to retrieve the fd for the file and call write(2) etc
751 https://rt.cpan.org/Ticket/Display.html?id=78843
753 - moved most of README to lib/Imager/Install.pod which should make it
754 more accessible to the "web" generation, also significantly updated
757 - updated README's for the separately distributed modules to refer to
758 Imager::Install, and that they need -dev versions of packages
759 https://rt.cpan.org/Ticket/Display.html?id=81265
761 - the JPEG test code now reports the compile-time library version
763 - avoid a possible compiler optimization issue on CentOS 5.9 i386 by
764 rearranging (and mildly optimizing) some code.
765 https://rt.cpan.org/Ticket/Display.html?id=83212
767 - fix a POD error in Imager::Fill (detected on new Pod-Simple)
768 https://rt.cpan.org/Ticket/Display.html?id=83434
770 - fix a broken link to Graphics::Magick
771 https://rt.cpan.org/Ticket/Display.html?id=82743
773 - drawing text to a channel with FT2 would draw with random coverage
774 due to an uninitialized alpha channel.
776 - marked the function pointer underlying the mm_log() API with the
777 correct gcc magic and fixed the resulting warnings.
779 - fixed some other compiler warnings
781 - Imager::Font::W32 now properly reports text drawing errors
782 https://rt.cpan.org/Ticket/Display.html?id=70098
784 - handle the SVf_UTF8 flag correctly on magic (eg. overloaded)
785 strings passed as text to draw(), bounding_box(), has_chars(),
786 glyph_names() (where supported) in each of the font drivers.
787 This may misbehave in perl 5.6.x since the UTF8 flag may not be
788 visible in the main SV after SvGETMAGIC().
789 https://rt.cpan.org/Ticket/Display.html?id=83438 (partial)
791 Imager 0.94 - 15 Dec 2012
792 =========================
794 Variations on some of these changes were included in development
797 - improved thread safety
798 - the internal error stack and log file handle are now in a per-thread
800 - JPEG now captures IPTC information in a thread-safe way
801 - avoid globals where possible for warning capture in libtiff
802 - use a mutex to avoid re-entering thread-unsafe giflib
803 - use a mutex to avoid re-entering thread-unsafe tifflib
804 - use a mutex to avoid re-entering thread-unsafe T1Lib
805 - use a library handle per thread for freetype 2.
806 - use an engine handle per thread for freetype 1.x.
807 - originally these changes broke ABI compatibility, this has been
810 - clarify the return value of getpixel();
811 https://rt.cpan.org/Ticket/Display.html?id=81198
813 - fixed a race condition in parallel testing for T1
815 - fixed a bug in handling yoff for untransformed image-based fills
817 - documentation improvements for Imager::Fill
819 - FT2: report the library version while testing.
821 Imager 0.93 - 15 Oct 2012
826 - previously a transparency enabled GIF write (the default) would
827 always use a GIF89a header even if none of the images were
830 - previously the probe step for freetype-config would fail on cygwin
832 - catch an invalid matrix parameter to convert() instead of crashing
833 https://rt.cpan.org/Ticket/Display.html?id=79922
835 - remove the 16-bit/sample limitation from the documentation for
836 setsamples(), it hasn't applied for many releases.
837 https://rt.cpan.org/Ticket/Display.html?id=79989
839 - don't copy setsamples() data parameter, it may be a large scalar
840 https://rt.cpan.org/Ticket/Display.html?id=79990
842 - clean up .dSYM directories generated performing probes on OS X
845 - pass the --verbose command-line option through to Imager::Probe in
846 sub-module's Makefile.PLs
847 https://rt.cpan.org/Ticket/Display.html?id=75878
851 - support for giflib 5.0. (5.0.1 and later)
852 https://rt.cpan.org/Ticket/Display.html?id=79029
853 The giflib API Imager uses doesn't have a mechanism to set the
854 header version in 5.0.0.
856 - update the GIF library probe code to check for the new giflib 5.0.1
857 EGifSetGifVersion() function, and to check for the giflib 4.2.0
858 uninitialized gif89 bug.
859 https://rt.cpan.org/Ticket/Display.html?id=79679
860 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
862 - avoid static variables when capturing IPTC data from JPEG files
864 - match Imager::Font::T1's error message translations to those from
865 later versions of T1Lib.
867 - for libtiff versions that support extended warning handlers (3.8.0
868 or later), use them to avoid some global variables.
870 - note Image::ExifTool for better metadata support.
871 https://rt.cpan.org/Ticket/Display.html?id=79251
873 Imager 0.92 - 14 Aug 2012
876 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
877 correctly for both probing and runtime.
878 https://rt.cpan.org/Ticket/Display.html?id=77672
880 - allow building JPEG/imexif.c on C89 compilers.
882 - allow building GIF/imgif.c on C89 compilers.
884 Imager 0.91 - 4 Jun 2012
889 - The size of rotated images is no longer rounded up so aggressively.
890 Added rounding to the linear interpolation done for rotate() and
891 matrix_transform() for 1 and 3 channel 8-bit images.
892 Adjusted the two tranlate matrices used to build the final rotation
893 matrix to use the distance between the outlier pixels rather than
894 the pixel dimensions (ie. dimension-1).
895 With all of this the output of rotate(degrees => 270) on an 8-bit
896 image exactly matches the output of rotate(right => 270).
897 https://rt.cpan.org/Ticket/Display.html?id=77063
901 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
902 internals, those names only matter for the XS interface.
904 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
905 the API level compiled into a loadable module such as
906 Imager::File::GIF doesn't match that of Imager. Previously it
907 could be difficult to determine exactly which module was failing to
909 https://rt.cpan.org/Ticket/Display.html?id=77173
911 - added Imager->check_file_limits() as an interface to the
912 i_int_check_image_file_limits() API.
914 - Imager->set_file_limits(reset => 1) now resets the limits to the
915 defaults rather than setting them all to unlimited.
917 - wrote a brief security note as Imager::Security
918 https://rt.cpan.org/Ticket/Display.html?id=68910
920 Imager 0.90 - 30 Apr 2012
925 - Imager::Test::is_imaged() attempted to process an "epsilon"
926 parameter but the prototype didn't allow for the extra parameter.
927 Corrected the prototype.
929 - when downconverting samples (eg. from floating point to 8 bit)
930 Imager now rounds the sample value rather than attempting to
931 allocate input values over output values equally. The old
932 behaviour had the probably surprising effect of converting a
933 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
935 This may result in slightly different 8 or 16-bit output images.
937 - BI_BITFIELD BMP images were handled incorrectly, both in
938 incorrectly calculating the space required for the masks and in
939 processing the image data itself.
940 https://rt.cpan.org/Ticket/Display.html?id=76736
942 - some odd width BMP BI_RLE4 images use run lengths that run one off
943 the edge of the image. Imager now allows this, discarding the
946 - odd length RLE4 runs in BMP images were decoded incorrectly.
948 - pkg-config could sometimes return a library that was in a directory
949 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
950 If no -L is included in the pkg-config library information check if
951 EU::MM can find the library, and if not, search our configured
952 directories and insert that into the library flags.
953 https://rt.cpan.org/Ticket/Display.html?id=75869
955 - Imager::Probe can now probe for libraries with dependent libraries,
956 common for static linking, eg. libpng requires libz.
957 https://rt.cpan.org/Ticket/Display.html?id=74043
959 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
961 - added alternative probe configurations that try to link libz, to
962 handle a statically linked libpng.
963 https://rt.cpan.org/Ticket/Display.html?id=74043
965 - if a probe includes testcode, Imager::Probe now checks that code as
966 part of the process of checking each configuration rather than as a
967 post test of the found configuration. This allows alternate
968 configurations to be checked if a matching but non-working
969 configuration is found.
970 https://rt.cpan.org/Ticket/Display.html?id=74043
974 - when reading or writing images via callbacks, the default callbacks
975 now push an error message indicating that a required callback was
976 called but not supplied.
977 https://rt.cpan.org/Ticket/Display.html?id=76782
979 - clarify which callbacks are required for reading and writing TIFF
982 - improve logging for creation of callback I/O layers.
984 - a little more documentation for Imager::Probe.
986 - the i_get_file_background() and i_get_file_backgroundf() APIs now
987 return int to indicate whether the i_background tag was found.
990 - improve error reporting
991 - add png_interlace, png_bits tags
992 - read paletted images as paletted images, including transparency
993 - read 1 bit greyscale images as a type suitable for other file
994 handlers to write as bilevel
995 - read 16 bit/sample PNG as 16-bit/sample Imager images
996 - write "bilevel" paletted images as 1 bit grayscale images
997 - write paletted images as paletted images
998 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
1000 - improved metadata support
1001 https://rt.cpan.org/Ticket/Display.html?id=29268
1003 Imager 0.89 - 18 Mar 2012
1008 - getpixel(..., type => "float") and the API i_gpixf() have been
1009 broken on paletted images since they were implemented.
1010 https://rt.cpan.org/Ticket/Display.html?id=75258
1014 - links in the METHOD INDEX now point at the method documentation
1015 rather than the heading you can find them under.
1016 https://rt.cpan.org/Ticket/Display.html?id=71495
1018 - Imager (and the bundled dynamic modules) no longer fallback to
1019 using DynaLoader if loading via XSLoader fails.
1020 For the bundled modules this could hide useful error messages.
1021 https://rt.cpan.org/Ticket/Display.html?id=75560
1023 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
1024 buffer in the array of allocations, but just stores the filename
1025 pointer and line number.
1026 https://rt.cpan.org/Ticket/Display.html?id=70388
1028 Imager 0.88 - 22 Feb 2012
1031 - describe how to build libgif etc on OS X in such a way as to be
1032 compatible with a fat binary perl (such as the system perl), in
1034 https://rt.cpan.org/Ticket/Display.html?id=73371
1036 - update the change notes for 0.77_01 to indicate that libungif
1037 support was removed.
1039 - add some other imaging modules to SEE ALSO
1040 https://rt.cpan.org/Ticket/Display.html?id=73906
1042 - note that the generator of the apparently non-DFSG-free postscript
1043 in MMOne.pfb is a Debian package.
1045 - setsamples() is now a true complement to getsamples() - it can
1046 write 8-bit or floating point samples from a scalar or array
1047 reference. This adds i_psamp() and i_psampf() to the C level API.
1049 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
1050 changed to make better use of the typemap, but these aren't part of
1051 the perl level API anyway. There were no changes to the C level
1052 interfaces to these functions.
1054 - getpixel() and setpixel() now accept a mix of scalar and array
1055 references for the x and y parameters, and unequal array lengths is
1057 https://rt.cpan.org/Ticket/Display.html?id=73697
1061 - correctly calculate the size of a rotated image
1062 https://rt.cpan.org/Ticket/Display.html?id=69261
1064 - fix incorrect rounding of color values for matrix_transform() and
1066 https://rt.cpan.org/Ticket/Display.html?id=69261
1068 - Win32 text output is now done in normal combine mode, the alpha
1069 component of the color is now significant.
1070 https://rt.cpan.org/Ticket/Display.html?id=70014
1072 - remove long unused gif case from read()
1073 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
1075 - the getsamples() target parameter was being treated as a hashref
1076 when it's meant to be an array reference.
1077 https://rt.cpan.org/Ticket/Display.html?id=74882
1079 - getpixel() and setpixel() now returns an empty list when invalid
1080 parameters are supplied.
1081 Invalid values for type now result in an error for getpixel().
1082 https://rt.cpan.org/Ticket/Display.html?id=73697
1084 Imager 0.87 - 03 Jan 2012
1087 - document the return value of the filter() method.
1088 https://rt.cpan.org/Ticket/Display.html?id=72369
1090 - document i_gsamp_bits() and i_psamp_bits().
1091 https://rt.cpan.org/Ticket/Display.html?id=68815
1093 - properly increment the Imager::Matrix2d $VERSION.
1095 - actually include the Imager::Test tests in the dist
1097 - correctly read and write 256x256 pixel ICO files
1098 https://rt.cpan.org/Ticket/Display.html?id=69599
1100 - make the error message from read() or read_multi() when they can't
1101 identify the file type match reality.
1102 https://rt.cpan.org/Ticket/Display.html?id=72475
1104 - read() now uses $FORMATGUESS if it can't determine the file type
1105 based on the file header, to match read_multi().
1107 - re-work and add tests for def_guess_type(). def_guess_type() no
1108 longer returns any random file extension as the file type.
1110 - add gray4, gray16 and gray as presets for make_colors.
1111 https://rt.cpan.org/Ticket/Display.html?id=67911
1113 - add make_palette() method that produces a palette from one or more
1116 - fix the Imager dependency for the separately distributed font
1118 https://rt.cpan.org/Ticket/Display.html?id=72643
1120 - fix i_render_color() to properly draw in "normal" mode - ie. when
1121 writing to a 1 or 3 channel image the second or fourth channel of
1122 the source color was being ignored, it is now significant.
1123 https://rt.cpan.org/Ticket/Display.html?id=71564
1125 Imager 0.86 - 31 Oct 2011
1128 - improve error reporting for W32 tests
1130 Imager 0.85_02 - 24 Oct 2011
1135 - eliminate unused i_gif_opts type (clean-up)
1136 https://rt.cpan.org/Ticket/Display.html?id=69245
1138 - fix combine=0 fill color anti-aliasing on the double/sample path
1139 https://rt.cpan.org/Ticket/Display.html?id=71309
1141 - make default text color non-transparent
1142 https://rt.cpan.org/Ticket/Display.html?id=71469
1144 - apply the last of the Debian unforwarded spelling fixes
1145 https://rt.cpan.org/Ticket/Display.html?id=70656
1147 - the log() method used its message parameter as a C level format
1149 https://rt.cpan.org/Ticket/Display.html?id=71653
1151 - provide our own STRLEN typemap entry for older perls.
1152 https://rt.cpan.org/Ticket/Display.html?id=71641
1154 - add extra ppport.h configuration to support older perls.
1156 - depend on Scalar::Util, since we use it and older perls don't have
1159 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
1160 to synthesize it from overloaded "".
1162 - use T1_StrError() for error messages on modern libt1
1163 https://rt.cpan.org/Ticket/Display.html?id=69879
1165 - actually load the font rather than just adding it to the catalog on
1168 - Imager::Font->new now produces better error messages for the T1
1171 - the font has_chars() method now returns perl's true and false
1172 values in list context rather than integers, which should be more
1174 https://rt.cpan.org/Ticket/Display.html?id=69158
1176 - the btm data structure used by the flood_fill code is now
1177 initialized more efficiently.
1178 https://rt.cpan.org/Ticket/Display.html?id=68994
1180 - updated the Thanks list in README
1181 https://rt.cpan.org/Ticket/Display.html?id=71607
1183 - check there's at least one coefficient for the convolution filter
1184 https://rt.cpan.org/Ticket/Display.html?id=68993
1186 - make the APIRef synopsis ordering consistent, older versions of
1187 perl could order it differently.
1188 https://rt.cpan.org/Ticket/Display.html?id=71675
1190 - we rely on Config.pm's d_vsnprintf as to whether we use
1191 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
1192 though it only has _ prefixed versions of these. Define our own
1193 prefixed names on Win32.
1194 https://rt.cpan.org/Ticket/Display.html?id=71642
1196 - fix library detection with MSVC
1198 - search a few more library directories, so EU::MM doesn't discard
1199 them. Hopefully fixes:
1200 https://rt.cpan.org/Ticket/Display.html?id=71643
1202 Imager 0.85_01 - 10 Oct 2011
1205 - add simple tests for the Imager::Test test_image generators
1207 - io_glue I/O buffering re-work:
1209 - reorganize io_glue to do it's own buffering by default
1211 - the unbuffered functions are available as i_io_raw_read() (or
1212 raw_read() from perl) etc but are not recommended for typical
1215 - use the new i_io_peekn() when checking for file magic to avoid
1216 seek, allowing Imager to detect the file type and read the file
1217 from an unseekable stream (for formats that don't use random
1220 - added several new I/O layer API functions.
1222 - fix the TGA performance problem, most noticably on Win32
1223 https://rt.cpan.org/Ticket/Display.html?id=70037
1225 - TIFF now uses wrapper functions of the correct types to avoid casts
1226 https://rt.cpan.org/Ticket/Display.html?id=69912
1228 - the callback IO object did its own buffering, controlled by the
1229 maxbuffer parameter supplied to the read() and write() methods.
1230 This buffering has been removed, to avoid redundancy with the
1231 common io_glue buffering. This also avoids a bug in that code
1232 which could rarely pass a zero length to the read callback and
1233 then panic about the result.
1235 - the callback IO object now tests the result of calling the close
1236 callback, which should return true for success.
1238 - the PNM reader did its own buffering. This buffering has been
1239 removed to avoid redundancy with the common io_glue buffering.
1241 - previously the read handlers for fd and callback I/O layers would
1242 call the underlying interface (POSIX read or your supplied callback)
1243 until it filled the buffer. It now only makes one call.
1245 - added public constructors for I/O layer objects (see Imager::IO)
1247 - all core file handlers now use the i_io_foo() wrappers to gain
1248 access to buffered I/O rather than calling the I/O layer
1251 - all core file handlers now check for error on close.
1253 - Backward compatibility: if you hava custom file handlers, you can
1254 use i_io_write() etc since they're available as macros in older
1257 - eliminate the final remnants of io_glue_commit_types().
1259 - bump IMAGER_API_VERSION, since the above may break assumptions.
1261 - removed the long unused i_gen_reader() and i_gen_writer() utility
1264 Imager 0.85 - 29 Aug 2011
1267 The main changes in the release versus 0.84 are:
1269 - on 64-bit systems, 64-bit types are consistently used for image
1270 dimensions and co-ordinated, and for memory block sizes.
1272 - handle IFD loops in TIFF files correctly. Previously this would
1273 lead to an infinite loop.
1277 - fix the link in the getheight() entry in the method index
1279 Imager 0.84_02 - 22 Aug 2011
1282 Development release, this will become 0.85 if CPAN testers is
1287 - the image file limits set by set_file_limits() weren't being
1288 checked when reading TIFF files.
1289 https://rt.cpan.org/Ticket/Display.html?id=69915
1291 - Provide more information about file format module load errors on a
1292 failed image file read() or write().
1293 https://rt.cpan.org/Ticket/Display.html?id=69194
1295 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
1296 through TIFF images, since it checks for IFD loops.
1297 https://rt.cpan.org/Ticket/Display.html?id=69914
1299 - don't leak memory when out of range palette indexes are supplied to
1301 https://rt.cpan.org/Ticket/Display.html?id=69242
1303 - require a later version of CPAN::Meta to ensure JSON::PP and
1304 CPAN::Meta::YAML are available.
1305 https://rt.cpan.org/Ticket/Display.html?id=69008
1307 - hoist the per-line calculations for the flines implementations, and
1308 modernize the tests a bit.
1309 https://rt.cpan.org/Ticket/Display.html?id=70126
1311 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
1312 them when available.
1313 https://rt.cpan.org/Ticket/Display.html?id=69147
1315 - if t1lib failed to reinitialize it would be left as marked
1317 https://rt.cpan.org/Ticket/Display.html?id=69877
1319 - update the bundled (and still modified) Devel::CheckLib
1320 https://rt.cpan.org/Ticket/Display.html?id=69170
1322 Imager 0.84_01 - 8 Aug 2011
1325 Development release as a sanity check for the types re-work.
1327 Massive types re-work:
1329 - the type used internally for pixel co-ordinates and image sizes is
1330 now 64-bit on 64-bit platforms (at least sane ones).
1332 - size_t is now used consistently for memory block sizes.
1334 - since this changes the binary interface, the Imager API version has
1335 been incremented. Any module that uses the API will need to be
1336 rebuilt. In most cases that will be enough, but calls to any APIs
1337 that take a pointer to image sizes may need source changes.
1339 - you should be able to create very large images on 64-bit systems,
1340 if you have enough memory. Successfully created a 32768 x 49192 x
1341 3 channel image, filled with a tiled image and scaled it. The
1342 unscaled image was also successfully saved to a JPEG.
1344 - check the image size before attempting to write BMP, GIF, JPEG,
1345 PNG, SGI, TGA, TIFF images.
1347 - correctly handle reading TGA images over 32767 pixels wide or tall.
1351 - the gif_left and gif_top tags are now clamped to non-negative
1352 values when writing a GIF image.
1354 - removed dead callback read/write code
1356 The default maximum memory size when reading files is now 1G.
1358 Imager 0.84 - 20 Jun 2011
1361 - Imager no longer inherits from Exporter (unless you're running an
1364 - Imager can now write progressive JPEGs (it could always read them).
1365 https://rt.cpan.org/Ticket/Display.html?id=68691
1369 - re-work, document and test Imager's logging facility.
1370 https://rt.cpan.org/Ticket/Display.html?id=65227
1372 - fix META.yml testing and the generated META.yml
1373 https://rt.cpan.org/Ticket/Display.html?id=65235
1375 - test and add error reporting to to_*() family methods
1377 - add to_rgb_double() method.
1378 https://rt.cpan.org/Ticket/Display.html?id=65101
1380 - Imager no longer exports anything by default
1381 https://rt.cpan.org/Ticket/Display.html?id=65228
1383 - convert colors to grayscale if the supplied (or generated) palette
1384 contains only grays when performing error diffusion color
1386 https://rt.cpan.org/Ticket/Display.html?id=68508
1388 - writing a paletted image to GIF wouldn't always use the colors
1389 supplied (or generated, eg. via make_colors => "mono"), which was
1391 https://rt.cpan.org/Ticket/Display.html?id=67912
1393 - replace (imager|tony)@imager.perl.org in the doc, since I don't
1394 plan to continue receiving mail at that address.
1395 https://rt.cpan.org/Ticket/Display.html?id=68591
1397 Imager 0.83 - 21 May 2011
1402 - diag() the error message on failure for some TIFF tests that are
1403 failing on a Solaris smoker.
1404 http://www.cpantesters.org/cpan/report/6396db1e-8090-11e0-9682-112b785ebe45
1406 Imager 0.82_01 - 17 May 2011
1409 Dev release, in case the compose tests are too sensitive.
1413 - Imager::Font::T1 incorrectly checked for absolute filename under
1414 Win32. Thanks to kmx for the report and fix.
1415 https://rt.cpan.org/Ticket/Display.html?id=67963
1417 - compose() with the target, source or mask position off the top or
1418 left of the target image didn't clip the source image correctly.
1419 https://rt.cpan.org/Ticket/Display.html?id=67220
1421 - compose() now returns a useful error message on a non-positive
1424 - compose.im now at 100% test coverage. (As opposed to, umm, much,
1427 Imager 0.82 - 14 Mar 2011
1432 - eliminate calls to i_has_format() from the test suite, since it's
1433 no longer a useful way to check for file format support. Eliminate
1434 i_has_format() from the functions exposed via XS.
1435 https://rt.cpan.org/Ticket/Display.html?id=65863
1437 - eliminate calls to note(), which isn't in the (very old) version of
1438 Test::More we have as a pre-requisite. note() is modern enough
1439 that I don't feel a need to require a Test::More upgrade for it.
1440 https://rt.cpan.org/Ticket/Display.html?id=65864
1442 - skip the threads tests on Test::More 2.00_*
1443 https://rt.cpan.org/Ticket/Display.html?id=65812
1445 - add an (unshipped) test to check Imager's internal POD links
1446 https://rt.cpan.org/Ticket/Display.html?id=65749
1448 - improve the library detection summary
1449 https://rt.cpan.org/Ticket/Display.html?id=9675
1451 - increase the version of Imager::Font::Type1 so that upgrades don't
1452 downgrade the version in this file.
1453 https://rt.cpan.org/Ticket/Display.html?id=66250
1455 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
1456 that option for the directories that would normally go in
1457 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.
1458 https://rt.cpan.org/Ticket/Display.html?id=65955
1460 Imager 0.81 - 14 Feb 2011
1463 - added coverage tests for masked images (maskimg.c @100% test coverage)
1465 - add hsv() method to Imager::Color
1466 Thanks to Leolo (Philip Gwyn)
1467 https://rt.cpan.org/Ticket/Display.html?id=65385
1469 - split libt1 Type 1 font support into a sub-module
1470 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1472 - add a preload() class method for use in forking servers, and to
1473 work around limitations in PAR.
1474 https://rt.cpan.org/Ticket/Display.html?id=65665
1478 - paletted writes to a masked image are now masked correctly.
1479 Revealed by new coverage tests.
1481 - update the filter plugin documentation.
1482 https://rt.cpan.org/Ticket/Display.html?id=56513
1484 - add the matrix() method to Imager::Matrix2d to allow creation of a
1485 matrix with specified co-efficients. You can now multiple an
1486 Imager::Matrix2d object by a 9 element array ref or a number.
1487 https://rt.cpan.org/Ticket/Display.html?id=29938
1489 - really fix loading TTF fonts with FT2 when FT1 isn't available.
1490 Thanks to Leolo (Philip Gwyn)
1491 https://rt.cpan.org/Ticket/Display.html?id=65386
1492 https://rt.cpan.org/Ticket/Display.html?id=62855
1494 - make sure each test script that needs testout/ creates it.
1495 https://rt.cpan.org/Ticket/Display.html?id=65088
1497 - handle a slightly different warning from libtiff 4.x
1498 https://rt.cpan.org/Ticket/Display.html?id=65268
1500 - the sat transform2() op returned an incorrect saturation.
1501 https://rt.cpan.org/Ticket/Display.html?id=65391
1503 Imager 0.80 - 17 Jan 2011
1506 - added coverage tests for Imager::Fountain and Imager::Color::Float
1508 - Imager is now maintained in git
1509 http://git.imager.perl.org/imager.git
1510 git://git.imager.perl.org/imager.git
1514 - images with an translucent alpha channel were not scaled correctly
1515 by the default (qtype=normal) scaling method.
1516 https://rt.cpan.org/Public/Bug/Display.html?id=63922
1518 - Imager::Color::Float now translates "#FFFFFF" to white instead of
1519 just a little darker.
1521 - make the default color map build algorithm "mediancut". This
1522 changes the default color map builder for writing GIFs back to what
1523 it was in 0.77, reverting a performance regression.
1524 https://rt.cpan.org/Ticket/Display.html?id=64785
1526 - handle failure to create a masked image correctly
1528 Imager 0.79 - 10 Dec 2010
1531 - add Imager::Test to the POD coverage tests and document the missing
1534 - the convert() method now optimizes the case where all output
1535 channels are either 0, sourced from a single input channel or 1.
1536 This significantly speeds up presets like "addalpha", "green".
1537 https://rt.cpan.org/Ticket/Display.html?id=51254
1539 - add wiggle.pl sample, as suggested by Dan Oppenheim.
1541 - add the combine() method to combine channels from multiple source
1542 images into a new image
1543 https://rt.cpan.org/Ticket/Display.html?id=11872
1547 - treat the co-efficients for convert() as doubles instead of floats.
1549 - If a higher (earlier) priority font handler failed to load, that
1550 would crash preventing loading of later font handlers.
1551 https://rt.cpan.org/Ticket/Display.html?id=62855
1553 - parse defines from the options returned by pkg-config --cflags
1554 https://rt.cpan.org/Ticket/Display.html?id=63223
1556 - a regen of the MANIFEST revealed that GIF and FT2 tests weren't
1557 included in the tarball. They are now included.
1559 Imager 0.78 - 4 Oct 2010
1564 - don't access deprecated members of the png_structp.
1565 https://rt.cpan.org/Ticket/Display.html?id=60242
1567 - document that using color objects is faster than supplying colors
1569 https://rt.cpan.org/Ticket/Display.html?id=61047
1571 - Imager::Probe now accepts array references for incpath and libpath.
1572 https://rt.cpan.org/Ticket/Display.html?id=60244
1574 Imager 0.77_02 - 27 Sep 2010
1577 - moved Win32, FreeType 2 font support into sub-modules.
1578 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1579 Uses Imager::Probe now.
1580 https://rt.cpan.org/Public/Bug/Display.html?id=61328
1582 - tested successfully with jpeg-8b
1583 https://rt.cpan.org/Ticket/Display.html?id=60221
1587 - from _01: look for missing file support test files in the right
1590 - flood_fill() wouldn't fill the right side of a single scan-line
1592 Thanks to Nicolas Roggli for reporting this.
1594 - flood_fill wouldn't fill to the left edge of the image if the
1595 starting line didn't reach the left edge.
1596 Thanks to Nicolas Roggli for reporting this.
1598 Imager 0.77_01 - 13 Sep 2010
1601 - add each library-directory/pkgconfig/ to the pkg-config search path
1603 Thanks to Justin Davis.
1604 https://rt.cpan.org/Ticket/Display.html?id=60491
1606 - moved GIF, TIFF, JPEG file handling code into sub-modules in
1607 preparation for separate distribution.
1608 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1610 Note: this removed support for libungif from Imager.
1612 - optimize filled box drawing (color, not fill)
1616 - Imager::Probe was calling ExtUtils::Liblist to initialize
1617 LD_RUN_PATH supplying an undefined value rather than the found
1618 directory. Thanks to Justin Davis.
1619 https://rt.cpan.org/Ticket/Display.html?id=60491
1621 - only prepend ./ to font filenames when passing them to T1Lib and
1622 then only when it would use its search mechanisms.
1623 https://rt.cpan.org/Ticket/Display.html?id=60509
1625 - fix the cache check for the X rgb.txt loader. This is typically
1626 used for color translation on Unix-like systems, and the fix
1627 improves performance of supplying colors by name by about 80 times.
1628 Test code that managed 3400 10x10 pixel boxes/second sped up to
1631 - clarify that Imager doesn't write EXIF metadata to images.
1632 https://rt.cpan.org/Ticket/Display.html?id=60637
1634 - Imager::Probe can now search subdirectories under its include path.
1635 Used by the PNG Makefile.PL to find headers and libraries when they
1636 aren't in the base directory, as in cygwin.
1637 https://rt.cpan.org/Ticket/Display.html?id=60635
1639 Imager 0.77 - 11 Aug 2010
1642 I don't want Imager::File::PNG indexed as part of Imager, but forgot
1643 to update the META.yml before updating the version.
1645 - don't index Imager::File::PNG as part of Imager
1647 - add resources to META.yml
1649 Imager 0.76 - not released
1654 - the align_string() method would ignore a string of "0" due to a
1655 mis-use of C< ||= >.
1656 Thanks to Maurice Height for reporting this.
1657 https://rt.cpan.org/Ticket/Display.html?id=60199
1659 Imager 0.75_03 - 09 Aug 2010
1664 - read_types() and write_types() would include png when it wasn't
1665 available due to a problem with the %formats tie
1667 - handle dependent libraries correctly (eg -lpng requiring -lz) in
1668 the code run phase of library probing.
1670 Imager 0.75_02 - 07 Aug 2010
1675 - add file missing from MANIFEST, which was causing TIFF failures.
1677 Imager 0.75_01 - 06 Aug 2010
1680 Test release for the new PNG probe.
1682 - added the ability to read multiple-image PNM files.
1683 Note that unlike the pbm/pgm/ppm specification this accepts mixed
1684 format files and allows white space padding between files.
1685 Thanks to Philip Gwyn (Leolo) for this patch.
1687 - moved the PNG file handling code into a sub-module in preparation
1688 for separate distribution.
1689 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
1690 Also helps avoid complications from -I/-L compile/link options from
1695 - Imager->new(data => $data) didn't try to process image file data in
1697 https://rt.cpan.org/Ticket/Display.html?id=58761
1699 - t/t50basicoo.t no longer depends on the other tests to generate its
1701 https://rt.cpan.org/Ticket/Display.html?id=9798
1702 Also, it wasn't testing pnm (pnm vs ppm mix-up)
1704 - update the documentation of hardinvert to match the change in 0.62.
1705 https://rt.cpan.org/Ticket/Display.html?id=59785
1707 - added hardinvertall filter which also inverts the alpha channel
1708 (sorry for the mess)
1710 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
1711 the probe can find the library for the test run.
1712 https://rt.cpan.org/Ticket/Display.html?id=57518
1714 Imager 0.75 - 20 Jun 2010
1717 - use PERL_NO_GET_CONTEXT to slightly improve performance on threaded
1718 perls (not measured)
1722 - an opacity fill based on a fountain fill would segfault when
1723 filling an 8-bit/sample image.
1725 - merge thickline branch polygon fix
1726 https://rt.cpan.org/Ticket/Display.html?id=43518
1728 Imager 0.74 - 7 May 2010
1733 - read_multi() didn't handle a missing file format library correctly,
1734 aborting on failing to call i_readgif_multi_wiol() or
1735 i_readtiff_multi_wiol().
1737 - fix spelling errors patched by Debian
1738 http://svn.debian.org/viewsvn/pkg-perl/trunk/libimager-perl/debian/patches/spelling.patch?revision=54839&view=markup
1740 - add an (unshipped) author test to spellcheck Imager's POD.
1742 - update the TIFF file format documentation
1743 https://rt.cpan.org/Ticket/Display.html?id=56510
1745 - lib/Imager/IO.pod was written almost 4 years ago but never shipped.
1747 Imager 0.73 - 15 Mar 2010
1750 - implement outline circles, both anti-aliased and not
1751 https://rt.cpan.org/Ticket/Display.html?id=19755
1753 - a combine => "none" fill to a 1 or 3 channel image would produce
1754 the incorrect colour.
1756 Imager 0.72 - 09 Dec 2009
1759 Bump version for release, since 0.71_03 is stable with CPAN testers.
1761 Imager 0.71_03 - 5 Dec 2009
1764 - further adjust the threads test so it only performs the tests on
1765 perls where it's expected to work, and only if the threads module
1768 Imager 0.71_02 - 1 Dec 2009
1771 - adjust the way we load the threads module for the threads test so
1772 it works with non-threaded perls
1774 Imager 0.71_01 - 30 Nov 2009
1779 - use scanline oriented operations to flip images instead of pixel
1781 https://rt.cpan.org/Ticket/Display.html?id=39278
1783 - use double/sample operations to flip large sample images instead of
1784 8-bit sample operations.
1785 https://rt.cpan.org/Ticket/Display.html?id=39280
1788 https://rt.cpan.org/Ticket/Display.html?id=51874
1790 - prevent double-frees when someone creates Imager objects and then
1791 creates a thread. Note: this just handles some simple cases,
1792 Imager doesn't support perl threads, and isn't likely to.
1793 https://rt.cpan.org/Ticket/Display.html?id=52268
1795 Imager 0.71 - 16 Nov 2009
1798 - add the opacity fill type - an adaptor that modifies the opacity of
1803 - the conv filter now enforces that the sum of the coefficients is
1804 non-zero. Also, rather than skipping pixels off the edge off the
1805 edge of the image, the closest edge pixel is used. Previously
1806 dividing by the zero sum of coefficients could cause invalid
1807 results or runtime exceptions.
1808 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
1811 Imager 0.70 - 21 Sep 2009
1816 - release image row and comments memory on all error returns in gif
1819 - handle zero length extensions, previously this would cause a null
1821 Thanks to Krzysztof Wojtaś for the test data and fix for this.
1823 - an integer division meant that preview scaling to below 1 pixel
1824 wide or high (which isn't too useful anyway) was calculating using
1825 NaNs on most platforms, and causing an exception on others.
1826 Thanks to David Cantrell for producing a backtrace of the crash on
1827 his Alpha-NetBSD CPAN test box which made it possible to track this
1830 Imager 0.69 - 08 Sep 2009
1835 - broken test fix - was attempting to call a function skip_all, when
1836 that should be a parameter to plan().
1838 - briefly document apidocs.perl, the tool used to build
1839 Imager::APIRef and make some minor enhancements
1841 - various minor documentation enhancements and fixes.
1843 Imager 0.68 - 07 Sep 2009
1846 - Imager->new(file => $filename) and other similar incantations will
1847 load the given file.
1848 https://rt.cpan.org/Ticket/Display.html?id=48261
1852 - avoid using CHECK as a label in Imager::Test
1853 http://nntp.x.perl.org/group/perl.cpan.testers/5220921
1855 - re-work most image file test files that require a library into
1856 separate library present/not present files to remove stupidly long
1859 - don't treat rubthrough() outside the bounds of the target image as
1861 http://nntp.x.perl.org/group/perl.cpan.testers/5185716
1863 Imager 0.67_01 - 02 Sep 2009
1868 - correct documentation of default of raw image interleave read
1870 https://rt.cpan.org/Ticket/Display.html?id=42074
1872 - add raw_ prefix to raw read parameters, though the original names
1875 - fail the read if an invalid raw_interleave parameter is supplied
1877 - warn if no interleave or raw_interleave parameter is supplied,
1878 since the documented default was wrong, and incompatible with the
1881 - for reading raw images, if raw_storechannels > raw_datachannels,
1882 set the extra channels in the image to 0
1884 - when probing for executables like freetype-config, search for .bat
1885 and .cmd on MSWin32, as well as .exe.
1886 https://rt.cpan.org/Ticket/Display.html?id=49275
1888 - re-work the external libraries section of README:
1889 - list Debian and Redhat package names for each library
1893 - use the new EU::MM META_MERGE facility instead of generating
1894 META.yml from scratch
1895 https://rt.cpan.org/Ticket/Display.html?id=47888
1897 - use Devel::CheckLib (bundled, modified) to check which release of
1898 libtiff is installed and reject 3.9.0
1899 http://bugzilla.maptools.org/show_bug.cgi?id=2088
1900 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543079
1902 Imager 0.67 - 12 Dec 2008
1907 - fix a packaging error
1909 Imager 0.66 - 12 Dec 2008
1912 - 24-bit color .ICO/.CUR files can now be read.
1916 - an optimization skipping 0 src alpha values could cause the
1917 rubthrough() to read past the end of a buffer.
1918 http://www.nntp.perl.org/group/perl.cpan.testers/2008/05/msg1509184.html
1920 - corrected a reference leak where writing GIFs would leak memory.
1921 This could also happen calling to_paletted().
1922 Also documented the underlying long existing feature where the
1923 colors parameter is filled with the generated color table and added
1925 http://rt.cpan.org/Ticket/Display.html?id=41028
1927 - write out the image size in bytes field of a BMP correctly.
1928 http://rt.cpan.org/Ticket/Display.html?id=41406
1930 - add limited tests for Imager::ExtUtils
1932 - make Imager::ExtUtils->includes use an absolute path, since
1933 a relative path could cause failures using Inline::C.
1934 http://rt.cpan.org/Ticket/Display.html?id=37353
1936 - re-arrange the POD for Imager::Font::BBox:
1937 - mark total_width(), pos_width(), end_offset() obsolete, since
1938 they're mostly for backwards compatibility
1939 - group width methods and height methods
1940 https://rt.cpan.org/Ticket/Display.html?id=39999
1942 Imager 0.65 - 20 May 2008
1947 - In some cases when an error occurs reading those parts of a JPEG
1948 file after the image the scan-line buffer could be freed a second
1949 time. In cases where the the error occured while reading the image
1950 data it's possible that the buffer could have leaked.
1951 Thanks to Gabriel Vasseur for reporting this and help in tracking
1954 - the gif_screen_height tag was overriding the screen width and being
1955 ignored for the screen height when present.
1956 https://rt.cpan.org/Public/Bug/Display.html?id=35568
1958 Imager 0.64 - 23 April 2008
1961 This is a bug fix release. This includes a fix for a possible
1966 - Possible security issue: The floating point sample path for image
1967 based fills had a buffer overflow. This would overwrite the end of
1968 a malloc()ed buffer with double precision floats.
1969 http://rt.cpan.org/Ticket/Display.html?id=35324
1972 - check that the result of fileno($fh) is defined rather than simply
1973 true when read() or write() is supplied with an fh parameter.
1974 http://rt.cpan.org/Ticket/Display.html?id=35139
1976 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1977 resulting in a SIGSEGV when attempting to scale an image to a size
1978 too large to fit in memory. This is a NULL pointer access issue,
1979 not a buffer overflow.
1980 Added a check for the failure.
1981 scale_calculate() (and hence scale()) will now fail if any of the
1982 scale size parameters are a reference.
1983 http://rt.cpan.org/Ticket/Display.html?id=35172
1985 - Regression: filling a greyscale image with a hatch used the wrong
1986 color channels from the supplied fg/bg colors.
1987 https://rt.cpan.org/Ticket/Display.html?id=35278
1989 - fixed a related problem for image fills.
1991 Imager 0.63 - 7 April 2008
1994 This release primarily contains changes to improve ease of use -
1995 rather than you having to convert images to the appropriate number of
1996 channels, Imager handles it internally. How to handle drawing colors
1997 and the default combine mode is a thornier problem left for some other
2000 - the font libraries are now only initialized when needed.
2001 http://rt.cpan.org/Ticket/Display.html?id=28825
2003 - moved the imtoc.perl code into Imager::Preprocess
2005 - paste() and rubthrough() now adapt the source image data to the
2006 destination, so you can now safely paste/rubthrough from greyscale
2007 images to color images or back, or from alpha channel images to
2008 noalpha channels or back.
2009 https://rt.cpan.org/Ticket/Display.html?id=30908
2011 - rubthrough() now falls back to pasting when the source doesn't have
2012 an alpha channel. This effectively treats the source as having a
2013 max alpha channel, the right thing to do.
2014 http://rt.cpan.org/Ticket/Display.html?id=29944
2016 - re-worked most of the area filling code to use a common set of
2017 functions when filling.
2018 Corrected normal combine mode.
2019 Rewrote most of the combine modes to match the way the SVG draft
2020 defines them with respect to a translucent source and destination.
2021 Added tests for translucent source and destination.
2022 Added tests to check 8-bit/sample and double/sample combines work
2024 https://rt.cpan.org/Ticket/Display.html?id=29879
2026 - writing a 2 or 4 channel image to a JPEG file will now write that
2027 image as if composited against a background, black by default,
2028 overridable with the i_background tag/parameter.
2029 https://rt.cpan.org/Ticket/Display.html?id=29876
2031 - writing a 2 or 4 channel image to a PGM/PPM file will now write
2032 that image as if composited against a background, black by default,
2033 overridable with the i_background tag/parameter.
2034 http://rt.cpan.org/Ticket/Display.html?id=30074
2036 - writing a 2 or 4 channel image to a BMP file will now write that
2037 image as if composited against a background, black by default,
2038 overridable with the i_background tag/parameter.
2039 http://rt.cpan.org/Ticket/Display.html?id=30075
2043 - Imager::Matrix2d->translate() now only requires one of the x or y
2045 http://rt.cpan.org/Ticket/Display.html?id=29937
2047 - mixing qtype scaling now sets all channels of a pixel to zero if
2048 the pixel has zero coverage (zero alpha). This should produce more
2049 compressible output files.
2050 http://rt.cpan.org/Ticket/Display.html?id=32324
2052 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
2054 https://bugzilla.redhat.com/show_bug.cgi?id=166254
2055 I'm not changing the #! lines of the sample code, since it's sample
2056 code, not intended for installation.
2057 http://rt.cpan.org/Ticket/Display.html?id=33408
2059 - some TGA images weren't being detected correctly as TGA images
2060 https://rt.cpan.org/Ticket/Display.html?id=32925
2062 - handling of the left-over bit for 16-bit/pixel TGA images has been
2063 changed to match the behaviour of the GIMP. Previously the bit
2064 being set was treated as an opaque pixel, but one user reported a
2065 problem with loading such an image. I haven't been able to find any
2066 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
2067 I'll match it's behaviour. See issue 114913 in the GIMP's
2069 http://rt.cpan.org/Ticket/Display.html?id=32926
2071 Imager 0.62 - 10 December 2007
2074 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
2075 to /path under your home directory.
2076 http://rt.cpan.org/Ticket/Display.html?id=29484
2078 - the old dynaload code used Mach API functions to load dynamic
2079 libraries on Mac OS X. These APIs have been deprecated in OS X
2080 10.5 and were causing some build problems.
2081 So henceforth Imager uses the dlopen() family of functions, and you
2082 will need version 10.3 or later of OS X.
2084 - added the det() function to the transform2() engine.
2085 added the sample quad_to_square.pl
2086 Courtesy Richard Fairhurst.
2087 http://rt.cpan.org/Ticket/Display.html?id=31244
2091 - samples/gifscale.pl sourced the base value for gif_top from
2093 Thanks to Eleneldil G. Arilou for pointing this out.
2095 - t/t82inline.t no longer loads B at runtime, to work around a bug
2096 in some 5.005_0[45] installations.
2097 http://rt.cpan.org/Ticket/Display.html?id=30508
2099 - work around Module::Depends::Intrusive bug #21229
2100 http://rt.cpan.org/Ticket/Display.html?id=30520
2102 - the hardinvert filter no-longer inverts the alpha channel.
2103 http://rt.cpan.org/Ticket/Display.html?id=30002
2105 - the hardinvert filter now supports large samples
2107 Imager 0.61_02 - 28 November 2007
2110 - major TIFF support re-work
2111 http://rt.cpan.org/Ticket/Display.html?id=20329
2113 - added a C level image interface for accessing samples from 1-32
2114 bits, exposed this at the perl level in getsamples()
2116 - the conv filter now works at floating point precision for high bit
2119 - added is_bilevel method to test whether an image should be written as
2120 a bilevel image if the image format supports it.
2122 - added -log-stderr as an Imager import list option
2124 - added some important types to Imager::APIRef
2126 - added test_image_double() to Imager::Test
2130 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
2133 - the scale() method with qtype mixing now handles images with an
2134 alpha channel correctly.
2136 - fixed a broken link from the "animated GIF" entry in the concept index.
2137 Thanks to Slaven Rezic.
2138 http://rt.cpan.org/Ticket/Display.html?id=30889
2140 - on some perl's the infix expression parser test would fail due to
2141 actions in the grammar returning false. Made sure all actions return
2143 Thanks to Richard Fairhurst for spending a lot of time in tracking
2145 http://rt.cpan.org/Public/Bug/Display.html?id=29562
2147 Imager 0.61 - 5 November 2007
2150 - added samples/gifscale.pl, which adjusts the screen size/position tags
2151 when scaling an animated gif
2152 http://rt.cpan.org/Ticket/Display.html?id=27591
2156 - correct handling of sz in matrix_transform() - this should allow
2157 perspective type transformations to work now.
2158 http://rt.cpan.org/Ticket/Display.html?id=29936
2160 - prevent a cast to integer warning on x64 builds in datatypes.c
2161 also fixed some other type warnings
2162 https://rt.cpan.org/Ticket/Display.html?id=30204
2164 - some sub-directory tests depended on files produced by the parent
2166 http://rt.cpan.org/Ticket/Display.html?id=30203
2168 - Imager::Font::Wrap doesn't correctly set savepos
2169 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
2170 http://rt.cpan.org/Ticket/Display.html?id=29771
2172 - test 171 in t/t01introvert.t was failing on perls configured to
2174 http://rt.cpan.org/Ticket/Display.html?id=29413
2176 - the code for the transform2() uminus operator was missing a break.
2177 Added tests for better code coverage of the ops.
2178 http://rt.cpan.org/Ticket/Display.html?id=29296
2180 - the SGI RLE compression code could overflow its compression buffer
2181 http://rt.cpan.org/Ticket/Display.html?id=30334
2183 - the 32-bit output function used by the SGI code only handled values
2184 under 0x10000. This was most noticable when writing large RLE images.
2185 http://rt.cpan.org/Ticket/Display.html?id=30335
2187 - validate chan_count for chans == NULL for each of the i_gsamp()
2189 http://rt.cpan.org/Ticket/Display.html?id=28985
2191 - attempt to work around the test failure at
2192 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
2193 http://rt.cpan.org/Ticket/Display.html?id=29562
2195 - improve the error messages produced when attempting to read or write
2196 an unknown image file format.
2197 http://rt.cpan.org/Ticket/Display.html?id=30103
2199 - improve the transform2() documentation
2200 http://rt.cpan.org/Ticket/Display.html?id=29267
2202 - correctly generate the author key in META.yml
2203 http://rt.cpan.org/Ticket/Display.html?id=30377
2205 - correctly blend a rotated (or matrix_transformed()) image when
2206 performing interpolation in the presence of an alpha channel.
2207 Also corrected the centring of the rotated image on the output
2210 Imager 0.60 - 30 August 2007
2213 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
2214 now has full SGI RGB image format, including RLE and 16-bit/sample
2216 https://rt.cpan.org/Ticket/Display.html?id=8666
2218 - logging functions are now available in the API
2220 - applied Gabriel Vasseur's patch
2221 added documentation, further tests, and support for greyscale images
2222 Obviously problems are my fault :)
2223 https://rt.cpan.org/Ticket/Display.html?id=28142
2225 - the mask for ICO/CUR images is now applied as an alpha channel to
2226 the returned image. For the old behaviour, supply ico_masked => 0
2227 to read() or read_multi(). This should be less confusing when
2228 using Imager as a general image processor.
2229 https://rt.cpan.org/Ticket/Display.html?id=29001
2233 - in some cases it's possible for giflib/libungif to return color
2234 indexes outside the range of colors defined by the image's palette.
2235 We now expand the palette to match the indexes used.
2236 Thanks to Gabriel Vasseur for reporting this.
2238 - fixed various memory leaks that could occur when failing to read png,
2239 jpeg, bmp or tga files.
2241 - to avoid confusion, channels not present in the image are returned as
2242 zero by getscanline(). This has no effect on the C level i_glin()
2243 and i_glinf() API functions which continue to not set the unused
2246 - the convert() method now returns an image of the same sample size as
2248 https://rt.cpan.org/Ticket/Display.html?id=28492
2250 - remove repeated text in Imager::Files
2251 http://rt.cpan.org/Ticket/Display.html?id=27589
2253 - be even more explicit that scale() and friends don't modify the source
2254 image, but return a new image.
2255 http://rt.cpan.org/Ticket/Display.html?id=28570
2257 - improve the error message from errstr() when you try to load a font
2258 for which the driver hasn't been built in Imager.
2259 http://rt.cpan.org/Ticket/Display.html?id=27571
2261 - transparency is now enabled by default when writing GIF images
2262 http://rt.cpan.org/Ticket/Display.html?id=27615
2264 - Imager would not load on Windows 98
2265 http://rt.cpan.org/Ticket/Display.html?id=27653
2267 Imager 0.59 - 14 June 2007
2272 - fixes a regression introduced by the fixes for RT 11972
2273 http://rt.cpan.org/Ticket/Display.html?id=27546
2275 - cropping outside the image would return an Imager object with
2276 no low-level image object, instead of returning false.
2277 Fixed by: Philip Gwyn (Leolo)
2278 http://rt.cpan.org/Ticket/Display.html?id=27509
2280 Imager 0.58 - 16 May 2007
2283 No significant changes from 0.57_01.
2285 Imager 0.57_01 - 11 May 2007
2288 - added to_rgb16 to produce a 16-bit/sample version of an image
2290 - improve freetype 1.x text output efficiency
2294 - search another place for rgb.txt, and check all the places
2295 Imager::Color checks when deciding whether to skip testing it
2296 http://rt.cpan.org/Ticket/Display.html?id=26064
2298 - use a convolution kernel size based on the stddev rather than a
2299 fixed size when performing a gaussian blur
2300 http://rt.cpan.org/Ticket/Display.html?id=25645
2302 - document the difference() method's mindist parameter, and debug it.
2304 - put the Imager release number in the Inline::C generated code to
2305 regenerate Inline code when a new release of Imager is installed.
2306 http://rt.cpan.org/Ticket/Display.html?id=26278
2308 - fix rendering on alpha channel images for the FreeType 1.x driver.
2309 http://rt.cpan.org/Ticket/Display.html?id=11972
2311 - fix rendering on alpha channel images for the T1lib driver.
2312 http://rt.cpan.org/Ticket/Display.html?id=11972
2314 - reworked library probing, we can now set more than one probe
2315 function for a library. Disabled the default (non-freetype-config)
2316 library probe and added an extra probe function that searches for
2317 both ft2build.h and whatever it includes, and adds -I as needed.
2318 Hopefully this will fix build problems like
2319 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
2320 http://rt.cpan.org/Ticket/Display.html?id=26086
2322 Imager 0.57 - 30 Apr 2007
2325 This is a maintenence release fixing a security issue in Imager.
2327 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
2328 overflow in malloced memory. There will be further discussion of
2329 this issue in the ticket below.
2330 http://rt.cpan.org/Ticket/Display.html?id=26811
2331 CVE-2007-2459 CVE-2007-2413
2332 The descriptions at cve.mitre.org varied in quality, please see the
2333 ticket at rt.cpan.org for a more accurate description of the issue.
2335 Imager 0.56 - 1 Apr 2007
2338 - added support for reading 16-bit/sample PGM/PPM images
2340 - added support for writing 16-bit/sample PGM/PPM images
2342 - improved performance of reading PBM/PGM/PPM images
2344 - added support for writing PBM images if the image is paletted and
2345 contains only black and white
2347 - added a new make_colors value - "mono"
2349 - switched from the svn log Changes to a manual Changes to reduce
2352 - new sample code - samples/flasher.pl
2356 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
2357 was returning an image object with an extra reference, this
2358 resulted in a memory leak.
2359 http://rt.cpan.org/Ticket/Display.html?id=24992
2361 - fix rendering on alpha channel images for the FreeType 2.x driver
2362 http://rt.cpan.org/Ticket/Display.html?id=11972
2364 - reading bmp files now consitently handles short reads. You can now
2365 supply a parameter to treat a short read as successful and set
2367 http://rt.cpan.org/Ticket/Display.html?id=8426
2369 - previously, reading ASCII PBM files required spaces between samples,
2370 even though the format doesn't require that
2372 - improved documentation of the unsharpmask filter (I hope)
2373 http://rt.cpan.org/Ticket/Display.html?id=25531
2375 - force flushing of the output from i_tt_dump_names() and test output
2376 in t/t35ttfont.t to prevent output from being mixed up.
2377 https://rt.cpan.org/Ticket/Display.html?id=24859
2379 - rewrite a conditional expression as an if() to hopefully work around
2380 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
2381 https://rt.cpan.org/Ticket/Display.html?id=25561
2383 - avoid Data::Dumper in regops.perl to support older releases of perl
2384 https://rt.cpan.org/Ticket/Display.html?id=24391
2386 Imager 0.55 - 16 Dec 2006
2389 This is primarily a bug fix release.
2391 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2393 There is one new feature:
2395 - the Win32 font driver now supports UTF8 (RT 22166)
2396 http://www.cpanforum.com/threads/3276
2397 http://rt.cpan.org/Ticket/Display.html?id=22166
2399 Several bugs were fixed:
2401 - the string() method would not output the string "0"
2402 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2404 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2405 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2407 - the gif_disposal and gif_user_input tags weren't being read from
2409 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2411 - gif.c was failing to build under MSVC
2412 http://rt.cpan.org/Ticket/Display.html?id=23922
2414 - in some cases strings passed to the string() method were treated as
2415 terminated by NUL (chr 0)
2416 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2418 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2419 that's the default build name for zlib on Win32.
2420 http://rt.cpan.org/Ticket/Display.html?id=23064
2422 - search $Config{incpath} for headers too, which we should have been
2425 Win32 font driver fixes:
2427 - the global descent value from bounding box was the wrong sign
2428 http://www.cpanforum.com/threads/3276
2430 - if the first or last glyph overflowed the left or right side of the
2431 advance width they would be clipped
2434 Imager 0.54 - 14 Sep 2006
2437 This is primarily a feature release:
2439 - a new qtype value 'mixing' has been added to the scale()
2440 method. This is faster than 'normal', slower than 'preview'. This
2441 is based on the method used by pnmscale, and seems to produce less
2442 blurry results than normal.
2443 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2445 - the rubthrough() method can now render onto images with an alpha
2447 http://rt.cpan.org/Ticket/Display.html?id=20678
2449 - the read_multi() method now falls back to calling doing a single
2450 image read via the read() method and write_multi() will now fall
2451 back to calling write() if a single image is supplied. This means
2452 you can simply call the read_multi() or write_multi() functions
2453 without having to check if the type is formatted by that method.
2454 http://rt.cpan.org/Ticket/Display.html?id=19457
2455 http://rt.cpan.org/Ticket/Display.html?id=19458
2457 - the GIF loop extension can now be written. If you don't have
2458 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2460 http://rt.cpan.org/Ticket/Display.html?id=21185
2462 - getscanline() and setscanline() can now read/write palette index
2463 based data from/to the image for paletted images, by setting type to
2465 http://rt.cpan.org/Ticket/Display.html?id=20338
2467 - we no longer hassle you to disable GIF support
2468 http://rt.cpan.org/Ticket/Display.html?id=20687
2470 - minor documentation fixes
2473 Imager 0.53 - 26 Jul 2006
2476 This is a bugfix release.
2478 Some test code was left in a code path not covered by the test
2479 suite. A test was added to cover this code path and the test code was
2481 http://rt.cpan.org/Public/Bug/Display.html?id=20705
2484 Imager 0.52 - 25 Jul 2006
2487 This is primarily a feature release, but contains a fair few bug
