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.

24 - only prepend ./ to font filenames when passing them to T1Lib and
25 then only when it would use its search mechanisms.

27

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.

34Imager 0.77 - 11 Aug 2010
35===========
36
37I don't want Imager::File::PNG indexed as part of Imager, but forgot
38to update the META.yml before updating the version.
39
40 - don't index Imager::File::PNG as part of Imager
41
42 - add resources to META.yml

45===========
46
47Bug fixes:
48
49 - the align_string() method would ignore a string of "0" due to a
50 mis-use of C< ||= >.
51 Thanks to Maurice Height for reporting this.

55==============
56
57Bug fixes:
58
59 - read_types() and write_types() would include png when it wasn't
60 available due to a problem with the %formats tie
61
62 - handle dependent libraries correctly (eg -lpng requiring -lz) in
63 the code run phase of library probing.

TC
77 - added the ability to read multiple-image PNM files.
78 Note that unlike the pbm/pgm/ppm specification this accepts mixed
79 format files and allows white space padding between files.
80 Thanks to Philip Gwyn (Leolo) for this patch.
81
1d7e3124
TC
82 - moved the PNG file handling code into a sub-module in preparation
83 for separate distribution.
84 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)

TC
94 - t/t50basicoo.t no longer depends on the other tests to generate its
95 input files.
96 https://rt.cpan.org/Ticket/Display.html?id=9798
97 Also, it wasn't testing pnm (pnm vs ppm mix-up)
98

99 - update the documentation of hardinvert to match the change in 0.62.
100 https://rt.cpan.org/Ticket/Display.html?id=59785
101

TC
102 - added hardinvertall filter which also inverts the alpha channel
103 (sorry for the mess)
104
10b85929
TC
105 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
106 the probe can find the library for the test run.

156Imager 0.71_03 - 5 Dec 2009
157==============
158
159 - further adjust the threads test so it only performs the tests on
160 perls where it's expected to work, and only if the threads module
161 can be loaded.

172Bug fixes:
173
174 - use scanline oriented operations to flip images instead of pixel
175 operations
176 https://rt.cpan.org/Ticket/Display.html?id=39278
177
178 - use double/sample operations to flip large sample images instead of
179 8-bit sample operations.

TC
182 - fix POD nits

184
ffddd407
TC
185 - prevent double-frees when someone creates Imager objects and then
186 creates a thread. Note: this just handles some simple cases,
187 Imager doesn't support perl threads, and isn't likely to.

193 - add the opacity fill type - an adaptor that modifies the opacity of
194 another fill.
195

TC
196Bug fixes:
197
198 - the conv filter now enforces that the sum of the coefficients is
199 non-zero. Also, rather than skipping pixels off the edge off the
200 edge of the image, the closest edge pixel is used. Previously
201 dividing by the zero sum of coefficients could cause invalid
202 results or runtime exceptions.
203 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
204 this bug.

209Bug fixes:
210
211 - release image row and comments memory on all error returns in gif
212 reader
213
214 - handle zero length extensions, previously this would cause a null
215 pointer dereference
216 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.
217

TC
218 - an integer division meant that preview scaling to below 1 pixel
219 wide or high (which isn't too useful anyway) was calculating using
220 NaNs on most platforms, and causing an exception on others.
221 Thanks to David Cantrell for producing a backtrace of the crash on
222 his Alpha-NetBSD CPAN test box which made it possible to track this
223 down.

TC
250 - re-work most image file test files that require a library into
251 separate library present/not present files to remove stupidly long
252 conditionals

254 - don't treat rubthrough() outside the bounds of the target image as
255 an error.

263 - correct documentation of default of raw image interleave read
264 parameter
265 https://rt.cpan.org/Ticket/Display.html?id=42074
266
267 - add raw_ prefix to raw read parameters, though the original names
268 still work.
269
270 - fail the read if an invalid raw_interleave parameter is supplied
271
272 - warn if no interleave or raw_interleave parameter is supplied,
273 since the documented default was wrong, and incompatible with the
274 write format
275
276 - for reading raw images, if raw_storechannels > raw_datachannels,
277 set the extra channels in the image to 0

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

TC
315 - corrected a reference leak where writing GIFs would leak memory.
316 This could also happen calling to_paletted().
317 Also documented the underlying long existing feature where the
318 colors parameter is filled with the generated color table and added
319 tests for it.

TC
331 - re-arrange the POD for Imager::Font::BBox:
332 - mark total_width(), pos_width(), end_offset() obsolete, since
333 they're mostly for backwards compatibility
334 - group width methods and height methods

340Bug fixes:
341
342 - In some cases when an error occurs reading those parts of a JPEG
343 file after the image the scan-line buffer could be freed a second
344 time. In cases where the the error occured while reading the image
345 data it's possible that the buffer could have leaked.
346 Thanks to Gabriel Vasseur for reporting this and help in tracking
347 it down.

e02d22d2
TC
361 - Possible security issue: The floating point sample path for image
362 based fills had a buffer overflow. This would overwrite the end of
363 a malloc()ed buffer with double precision floats.

e02d22d2 366
de470892
TC
367 - check that the result of fileno($fh) is defined rather than simply
368 true when read() or write() is supplied with an fh parameter.
369 http://rt.cpan.org/Ticket/Display.html?id=35139
370
371 - i_scale_axis() wasn't checking the result of i_img_new_ch()
372 resulting in a SIGSEGV when attempting to scale an image to a size
373 too large to fit in memory. This is a NULL pointer access issue,
374 not a buffer overflow.
375 Added a check for the failure.
376 scale_calculate() (and hence scale()) will now fail if any of the
377 scale size parameters are a reference.

242d7497
TC
389This release primarily contains changes to improve ease of use -
390rather than you having to convert images to the appropriate number of
391channels, Imager handles it internally. How to handle drawing colors
392and the default combine mode is a thornier problem left for some other
393release.
394

395 - the font libraries are now only initialized when needed.

397

TC
398 - moved the imtoc.perl code into Imager::Preprocess
399
400 - paste() and rubthrough() now adapt the source image data to the
401 destination, so you can now safely paste/rubthrough from greyscale
402 images to color images or back, or from alpha channel images to
403 noalpha channels or back.
404 https://rt.cpan.org/Ticket/Display.html?id=30908
405
406 - rubthrough() now falls back to pasting when the source doesn't have
407 an alpha channel. This effectively treats the source as having a
408 max alpha channel, the right thing to do.
409 http://rt.cpan.org/Ticket/Display.html?id=29944
410
411 - re-worked most of the area filling code to use a common set of
412 functions when filling.
413 Corrected normal combine mode.
414 Rewrote most of the combine modes to match the way the SVG draft
415 defines them with respect to a translucent source and destination.
416 Added tests for translucent source and destination.
417 Added tests to check 8-bit/sample and double/sample combines work
418 similarly.

TC
442 - mixing qtype scaling now sets all channels of a pixel to zero if
443 the pixel has zero coverage (zero alpha). This should produce more
444 compressible output files.

447 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
448 Noticed when I saw:
449 https://bugzilla.redhat.com/show_bug.cgi?id=166254
450 I'm not changing the #! lines of the sample code, since it's sample
451 code, not intended for installation.

TC
454 - some TGA images weren't being detected correctly as TGA images
455 https://rt.cpan.org/Ticket/Display.html?id=32925
456
457 - handling of the left-over bit for 16-bit/pixel TGA images has been
458 changed to match the behaviour of the GIMP. Previously the bit
459 being set was treated as an opaque pixel, but one user reported a
460 problem with loading such an image. I haven't been able to find any
461 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
462 I'll match it's behaviour. See issue 114913 in the GIMP's
463 bugzilla.

473 - the old dynaload code used Mach API functions to load dynamic
474 libraries on Mac OS X. These APIs have been deprecated in OS X
475 10.5 and were causing some build problems.
476 So henceforth Imager uses the dlopen() family of functions, and you
477 will need version 10.3 or later of OS X.

781Imager 0.55 - 16 Dec 2006
782===========
783
784This is primarily a bug fix release.
785
786Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
787
788There is one new feature:
789
790 - the Win32 font driver now supports UTF8 (RT 22166)
791 http://www.cpanforum.com/threads/3276
792 http://rt.cpan.org/Ticket/Display.html?id=22166
793
794Several bugs were fixed:
795
796 - the string() method would not output the string "0"
797 http://rt.cpan.org/Public/Bug/Display.html?id=21770
798
799 - fills.c was failing to compile on Solaris 10 (compiler unknown)
800 http://rt.cpan.org/Public/Bug/Display.html?id=21944
801
802 - the gif_disposal and gif_user_input tags weren't being read from
803 the file correctly
804 http://rt.cpan.org/Public/Bug/Display.html?id=22192
805
806 - gif.c was failing to build under MSVC
807 http://rt.cpan.org/Ticket/Display.html?id=23922
808
809 - in some cases strings passed to the string() method were treated as
810 terminated by NUL (chr 0)
811 http://rt.cpan.org/Public/Bug/Display.html?id=21770
812
813 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
814 that's the default build name for zlib on Win32.
815 http://rt.cpan.org/Ticket/Display.html?id=23064
816
817 - search $Config{incpath} for headers too, which we should have been
818 doing all along.
819
820Win32 font driver fixes:
821
822 - the global descent value from bounding box was the wrong sign
823 http://www.cpanforum.com/threads/3276
824
825 - if the first or last glyph overflowed the left or right side of the
826 advance width they would be clipped
827
828
829Imager 0.54 - 14 Sep 2006
830===========
831
832This is primarily a feature release:
833
834 - a new qtype value 'mixing' has been added to the scale()
835 method. This is faster than 'normal', slower than 'preview'. This
836 is based on the method used by pnmscale, and seems to produce less
837 blurry results than normal.
838 http://rt.cpan.org/Public/Bug/Display.html?id=20677
839
840 - the rubthrough() method can now render onto images with an alpha
841 channel.
842 http://rt.cpan.org/Ticket/Display.html?id=20678
843
844 - the read_multi() method now falls back to calling doing a single
845 image read via the read() method and write_multi() will now fall
846 back to calling write() if a single image is supplied. This means
847 you can simply call the read_multi() or write_multi() functions
848 without having to check if the type is formatted by that method.
849 http://rt.cpan.org/Ticket/Display.html?id=19457
850 http://rt.cpan.org/Ticket/Display.html?id=19458
851
852 - the GIF loop extension can now be written. If you don't have
853 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
854 should upgrade.
855 http://rt.cpan.org/Ticket/Display.html?id=21185
856
857 - getscanline() and setscanline() can now read/write palette index
858 based data from/to the image for paletted images, by setting type to
859 'index'.
860 http://rt.cpan.org/Ticket/Display.html?id=20338
861
862 - we no longer hassle you to disable GIF support
863 http://rt.cpan.org/Ticket/Display.html?id=20687
864
865 - minor documentation fixes
866
867
868Imager 0.53 - 26 Jul 2006
869===========
870
871This is a bugfix release.
872
873Some test code was left in a code path not covered by the test
874suite. A test was added to cover this code path and the test code was
875removed.
876http://rt.cpan.org/Public/Bug/Display.html?id=20705
877
878
879Imager 0.52 - 25 Jul 2006
880===========
881
882This is primarily a feature release, but contains a fair few bug
883fixes, new features:
884
885 - ability to read and write MS Windows ICO and CUR files
886
887 - you can now add file format plugins to support new file formats
888
889 - add POD coverage tests
890
891 - setcolors() and addcolors() now accept color names and so on
892 instead of requiring Imager::Color objects.
893 http://rt.cpan.org/Ticket/Display.html?id=20056
894
895 - flood_fill() can now fill to a specified border color instead of
896 just to the area the same color as the seed.
897 http://rt.cpan.org/Ticket/Display.html?id=19618
898
899
900Bug fixes:
901
902 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
903 calculating the advance width.
904 http://rt.cpan.org/Public/Bug/Display.html?id=20554
905
906 - bounding_box for the T1 driver wasn't including leading and
907 trailing spaces in the bounding box as the other drivers did, it also
908 produced strange results for empty strings or strings containing only
909 spaces
910
911 - when reading CMYK jpeg images they were being transferred to the
912 image object as is, producing a four channel image. It only looked ok
913 due to an old still unfixed Photoshop bug. We now convert from the
914 inverted CMYK that photoshop (and Corel for example) produce into RGB.
915 http://rt.cpan.org/Ticket/Display.html?id=20416
916
917 - reading a CYMK TIFF would result in a 4 channel image, reading any
918 image with more than 4 channels (eg. RGB with 2 alpha channels) would
919 result in an error.
920 http://rt.cpan.org/Ticket/Display.html?id=20415
921
922 - added /usr/local/include to the default include search path, since
923 we were already searching /usr/local/lib for libraries.
924
