6 - add each library-directory/pkgconfig/ to the pkg-config search path
7 in Imager::Probe.
8 Thanks to Justin Davis.

TC
17Bug fixes:
18
19 - Imager::Probe was calling ExtUtils::Liblist to initialize
20 LD_RUN_PATH supplying an undefined value rather than the found
21 directory. Thanks to Justin Davis.

TC
24 - only prepend ./ to font filenames when passing them to T1Lib and
25 then only when it would use its search mechanisms.
26 https://rt.cpan.org/Ticket/Display.html?id=60509
27
173c91ba
TC
28 - fix the cache check for the X rgb.txt loader. This is typically
29 used for color translation on Unix-like systems, and improves
30 performance of supplying colors by name by about 80 times. Test
31 code that managed 3400 10x10 pixel boxes/second sped up to 25700
32 boxes/second.
b851aeeb 33
d3a96113
TC
34 - clarify that Imager doesn't write EXIF metadata to images.
35 https://rt.cpan.org/Ticket/Display.html?id=60637
36
37 - Imager::Probe can now search subdirectories under its include path.
38 Used by the PNG Makefile.PL to find headers and libraries when they
39 aren't in the base directory, as in cygwin.

42Imager 0.77 - 11 Aug 2010
43===========
44
45I don't want Imager::File::PNG indexed as part of Imager, but forgot
46to update the META.yml before updating the version.
47
48 - don't index Imager::File::PNG as part of Imager
49
50 - add resources to META.yml
51
52Imager 0.76 - not released

TC
53===========
54
55Bug fixes:
56
57 - the align_string() method would ignore a string of "0" due to a
58 mis-use of C< ||= >.
59 Thanks to Maurice Height for reporting this.

62Imager 0.75_03 - 09 Aug 2010
63==============
64
65Bug fixes:
66
67 - read_types() and write_types() would include png when it wasn't
68 available due to a problem with the %formats tie
69
70 - handle dependent libraries correctly (eg -lpng requiring -lz) in
71 the code run phase of library probing.

81==============
82
83Test release for the new PNG probe.

TC
85 - added the ability to read multiple-image PNM files.
86 Note that unlike the pbm/pgm/ppm specification this accepts mixed
87 format files and allows white space padding between files.
88 Thanks to Philip Gwyn (Leolo) for this patch.
89
1d7e3124
TC
90 - moved the PNG file handling code into a sub-module in preparation
91 for separate distribution.
92 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)
93 Also helps avoid complications from -I/-L compile/link options from
94 other libraries.

96Bugs:
97
98 - Imager->new(data => $data) didn't try to process image file data in
99 $data
100 https://rt.cpan.org/Ticket/Display.html?id=58761
101
b6071a43
TC
102 - t/t50basicoo.t no longer depends on the other tests to generate its
103 input files.
104 https://rt.cpan.org/Ticket/Display.html?id=9798
105 Also, it wasn't testing pnm (pnm vs ppm mix-up)
106
a9da425a
TC
107 - update the documentation of hardinvert to match the change in 0.62.
108 https://rt.cpan.org/Ticket/Display.html?id=59785
109
5558f899
TC
110 - added hardinvertall filter which also inverts the alpha channel
111 (sorry for the mess)
112
10b85929
TC
113 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
114 the probe can find the library for the test run.

134Bug fixes:
135
136 - read_multi() didn't handle a missing file format library correctly,
137 aborting on failing to call i_readgif_multi_wiol() or
138 i_readtiff_multi_wiol().
139

TC
164Imager 0.71_03 - 5 Dec 2009
165==============
166
167 - further adjust the threads test so it only performs the tests on
168 perls where it's expected to work, and only if the threads module
169 can be loaded.

178===========
179
180Bug fixes:
181
182 - use scanline oriented operations to flip images instead of pixel
183 operations
184 https://rt.cpan.org/Ticket/Display.html?id=39278
185
186 - use double/sample operations to flip large sample images instead of
187 8-bit sample operations.

TC
190 - fix POD nits
191 https://rt.cpan.org/Ticket/Display.html?id=51874
192
ffddd407
TC
193 - prevent double-frees when someone creates Imager objects and then
194 creates a thread. Note: this just handles some simple cases,
195 Imager doesn't support perl threads, and isn't likely to.

TC
201 - add the opacity fill type - an adaptor that modifies the opacity of
202 another fill.
203

TC
204Bug fixes:
205
206 - the conv filter now enforces that the sum of the coefficients is
207 non-zero. Also, rather than skipping pixels off the edge off the
208 edge of the image, the closest edge pixel is used. Previously
209 dividing by the zero sum of coefficients could cause invalid
210 results or runtime exceptions.
211 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
212 this bug.

TC
215===========
216
217Bug fixes:
218
219 - release image row and comments memory on all error returns in gif
220 reader
221
222 - handle zero length extensions, previously this would cause a null
223 pointer dereference
224 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.
225
b3afeed5
TC
226 - an integer division meant that preview scaling to below 1 pixel
227 wide or high (which isn't too useful anyway) was calculating using
228 NaNs on most platforms, and causing an exception on others.
229 Thanks to David Cantrell for producing a backtrace of the crash on
230 his Alpha-NetBSD CPAN test box which made it possible to track this
231 down.

238 - broken test fix - was attempting to call a function skip_all, when
239 that should be a parameter to plan().
240

0d670555
TC
258 - re-work most image file test files that require a library into
259 separate library present/not present files to remove stupidly long
260 conditionals
261
262 - don't treat rubthrough() outside the bounds of the target image as
263 an error.

271 - correct documentation of default of raw image interleave read
272 parameter
273 https://rt.cpan.org/Ticket/Display.html?id=42074
274
275 - add raw_ prefix to raw read parameters, though the original names
276 still work.
277
278 - fail the read if an invalid raw_interleave parameter is supplied
279
280 - warn if no interleave or raw_interleave parameter is supplied,
281 since the documented default was wrong, and incompatible with the
282 write format
283
284 - for reading raw images, if raw_storechannels > raw_datachannels,
285 set the extra channels in the image to 0
286
cd476e58
TC
287 - when probing for executables like freetype-config, search for .bat
288 and .cmd on MSWin32, as well as .exe.

TC
319 - an optimization skipping 0 src alpha values could cause the
320 rubthrough() to read past the end of a buffer.

322
5c0d0ddf
TC
323 - corrected a reference leak where writing GIFs would leak memory.
324 This could also happen calling to_paletted().
325 Also documented the underlying long existing feature where the
326 colors parameter is filled with the generated color table and added
327 tests for it.

TC
333 - add limited tests for Imager::ExtUtils
334
335 - make Imager::ExtUtils->includes use an absolute path, since

338
6b22ba84
TC
339 - re-arrange the POD for Imager::Font::BBox:
340 - mark total_width(), pos_width(), end_offset() obsolete, since
341 they're mostly for backwards compatibility
342 - group width methods and height methods

346===========
347
348Bug fixes:
349
350 - In some cases when an error occurs reading those parts of a JPEG
351 file after the image the scan-line buffer could be freed a second
352 time. In cases where the the error occured while reading the image
353 data it's possible that the buffer could have leaked.
354 Thanks to Gabriel Vasseur for reporting this and help in tracking
355 it down.

TC
367Bug fixes:
368
e02d22d2
TC
369 - Possible security issue: The floating point sample path for image
370 based fills had a buffer overflow. This would overwrite the end of
371 a malloc()ed buffer with double precision floats.
372 http://rt.cpan.org/Ticket/Display.html?id=35324
6912d85a 373 CVE-2008-1928
e02d22d2 374
de470892
TC
375 - check that the result of fileno($fh) is defined rather than simply
376 true when read() or write() is supplied with an fh parameter.
377 http://rt.cpan.org/Ticket/Display.html?id=35139
378
379 - i_scale_axis() wasn't checking the result of i_img_new_ch()
380 resulting in a SIGSEGV when attempting to scale an image to a size
381 too large to fit in memory. This is a NULL pointer access issue,
382 not a buffer overflow.
383 Added a check for the failure.
384 scale_calculate() (and hence scale()) will now fail if any of the
385 scale size parameters are a reference.

TC
397This release primarily contains changes to improve ease of use -
398rather than you having to convert images to the appropriate number of
399channels, Imager handles it internally. How to handle drawing colors
400and the default combine mode is a thornier problem left for some other
401release.
402

TC
403 - the font libraries are now only initialized when needed.

405
9b1ec2b8
TC
406 - moved the imtoc.perl code into Imager::Preprocess
407
408 - paste() and rubthrough() now adapt the source image data to the
409 destination, so you can now safely paste/rubthrough from greyscale
410 images to color images or back, or from alpha channel images to
411 noalpha channels or back.
412 https://rt.cpan.org/Ticket/Display.html?id=30908
413
414 - rubthrough() now falls back to pasting when the source doesn't have
415 an alpha channel. This effectively treats the source as having a
416 max alpha channel, the right thing to do.
417 http://rt.cpan.org/Ticket/Display.html?id=29944
418
419 - re-worked most of the area filling code to use a common set of
420 functions when filling.
421 Corrected normal combine mode.
422 Rewrote most of the combine modes to match the way the SVG draft
423 defines them with respect to a translucent source and destination.
424 Added tests for translucent source and destination.
425 Added tests to check 8-bit/sample and double/sample combines work
426 similarly.

449
2757bad0
TC
450 - mixing qtype scaling now sets all channels of a pixel to zero if
451 the pixel has zero coverage (zero alpha). This should produce more
452 compressible output files.
453 http://rt.cpan.org/Ticket/Display.html?id=32324

3da08517
TC
455 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
456 Noticed when I saw:
457 https://bugzilla.redhat.com/show_bug.cgi?id=166254
458 I'm not changing the #! lines of the sample code, since it's sample
459 code, not intended for installation.

465 - handling of the left-over bit for 16-bit/pixel TGA images has been
466 changed to match the behaviour of the GIMP. Previously the bit
467 being set was treated as an opaque pixel, but one user reported a
468 problem with loading such an image. I haven't been able to find any
469 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
470 I'll match it's behaviour. See issue 114913 in the GIMP's
471 bugzilla.

481 - the old dynaload code used Mach API functions to load dynamic
482 libraries on Mac OS X. These APIs have been deprecated in OS X
483 10.5 and were causing some build problems.
484 So henceforth Imager uses the dlopen() family of functions, and you
485 will need version 10.3 or later of OS X.

792This is primarily a bug fix release.
793
794Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
795
796There is one new feature:
797
798 - the Win32 font driver now supports UTF8 (RT 22166)
799 http://www.cpanforum.com/threads/3276
800 http://rt.cpan.org/Ticket/Display.html?id=22166
801
802Several bugs were fixed:
803
804 - the string() method would not output the string "0"
805 http://rt.cpan.org/Public/Bug/Display.html?id=21770
806
807 - fills.c was failing to compile on Solaris 10 (compiler unknown)
808 http://rt.cpan.org/Public/Bug/Display.html?id=21944
809
810 - the gif_disposal and gif_user_input tags weren't being read from
811 the file correctly
812 http://rt.cpan.org/Public/Bug/Display.html?id=22192
813
814 - gif.c was failing to build under MSVC
815 http://rt.cpan.org/Ticket/Display.html?id=23922
816
817 - in some cases strings passed to the string() method were treated as
818 terminated by NUL (chr 0)
819 http://rt.cpan.org/Public/Bug/Display.html?id=21770
820
821 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
822 that's the default build name for zlib on Win32.
823 http://rt.cpan.org/Ticket/Display.html?id=23064
824
825 - search $Config{incpath} for headers too, which we should have been
826 doing all along.
827
828Win32 font driver fixes:
829
830 - the global descent value from bounding box was the wrong sign
831 http://www.cpanforum.com/threads/3276
832
833 - if the first or last glyph overflowed the left or right side of the
834 advance width they would be clipped
835
836
837Imager 0.54 - 14 Sep 2006
838===========
839
840This is primarily a feature release:
841
842 - a new qtype value 'mixing' has been added to the scale()
843 method. This is faster than 'normal', slower than 'preview'. This
844 is based on the method used by pnmscale, and seems to produce less
845 blurry results than normal.
846 http://rt.cpan.org/Public/Bug/Display.html?id=20677
847
848 - the rubthrough() method can now render onto images with an alpha
849 channel.
850 http://rt.cpan.org/Ticket/Display.html?id=20678
851
852 - the read_multi() method now falls back to calling doing a single
853 image read via the read() method and write_multi() will now fall
854 back to calling write() if a single image is supplied. This means
855 you can simply call the read_multi() or write_multi() functions
856 without having to check if the type is formatted by that method.
857 http://rt.cpan.org/Ticket/Display.html?id=19457
858 http://rt.cpan.org/Ticket/Display.html?id=19458
859
860 - the GIF loop extension can now be written. If you don't have
861 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
862 should upgrade.
863 http://rt.cpan.org/Ticket/Display.html?id=21185
864
865 - getscanline() and setscanline() can now read/write palette index
866 based data from/to the image for paletted images, by setting type to
867 'index'.
868 http://rt.cpan.org/Ticket/Display.html?id=20338
869
870 - we no longer hassle you to disable GIF support
871 http://rt.cpan.org/Ticket/Display.html?id=20687
872
873 - minor documentation fixes
874
875
876Imager 0.53 - 26 Jul 2006
877===========
878
879This is a bugfix release.
880
881Some test code was left in a code path not covered by the test
882suite. A test was added to cover this code path and the test code was
883removed.
884http://rt.cpan.org/Public/Bug/Display.html?id=20705

886
887Imager 0.52 - 25 Jul 2006
888===========
889
890This is primarily a feature release, but contains a fair few bug
891fixes, new features:
892
893 - ability to read and write MS Windows ICO and CUR files
894
895 - you can now add file format plugins to support new file formats
896
897 - add POD coverage tests
898
899 - setcolors() and addcolors() now accept color names and so on
900 instead of requiring Imager::Color objects.
901 http://rt.cpan.org/Ticket/Display.html?id=20056
902
903 - flood_fill() can now fill to a specified border color instead of
904 just to the area the same color as the seed.
905 http://rt.cpan.org/Ticket/Display.html?id=19618
906
907
908Bug fixes:
909
910 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
911 calculating the advance width.
912 http://rt.cpan.org/Public/Bug/Display.html?id=20554
913
914 - bounding_box for the T1 driver wasn't including leading and
915 trailing spaces in the bounding box as the other drivers did, it also
916 produced strange results for empty strings or strings containing only
917 spaces
918
919 - when reading CMYK jpeg images they were being transferred to the
920 image object as is, producing a four channel image. It only looked ok
921 due to an old still unfixed Photoshop bug. We now convert from the
922 inverted CMYK that photoshop (and Corel for example) produce into RGB.
