16Bug fixes:
17
18 - read_types() and write_types() would include png when it wasn't
19 available due to a problem with the %formats tie
20
21 - handle dependent libraries correctly (eg -lpng requiring -lz) in
22 the code run phase of library probing.

TC
36 - added the ability to read multiple-image PNM files.
37 Note that unlike the pbm/pgm/ppm specification this accepts mixed
38 format files and allows white space padding between files.
39 Thanks to Philip Gwyn (Leolo) for this patch.

TC
41 - moved the PNG file handling code into a sub-module in preparation
42 for separate distribution.
43 https://rt.cpan.org/Ticket/Display.html?id=49616 (partial)

53 - t/t50basicoo.t no longer depends on the other tests to generate its
54 input files.
55 https://rt.cpan.org/Ticket/Display.html?id=9798
56 Also, it wasn't testing pnm (pnm vs ppm mix-up)
57

61 - added hardinvertall filter which also inverts the alpha channel
62 (sorry for the mess)
63
10b85929
TC
64 - when probing for TIFF, set LD_RUN_PATH just as the Makefile does so
65 the probe can find the library for the test run.

115Imager 0.71_03 - 5 Dec 2009
116==============
117
118 - further adjust the threads test so it only performs the tests on
119 perls where it's expected to work, and only if the threads module
120 can be loaded.

134 operations
135 https://rt.cpan.org/Ticket/Display.html?id=39278
136
137 - use double/sample operations to flip large sample images instead of
138 8-bit sample operations.

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

152 - add the opacity fill type - an adaptor that modifies the opacity of
153 another fill.
154

TC
155Bug fixes:
156
157 - the conv filter now enforces that the sum of the coefficients is
158 non-zero. Also, rather than skipping pixels off the edge off the
159 edge of the image, the closest edge pixel is used. Previously
160 dividing by the zero sum of coefficients could cause invalid
161 results or runtime exceptions.
162 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
163 this bug.

TC
166===========
167
168Bug fixes:
169
170 - release image row and comments memory on all error returns in gif
171 reader
172
173 - handle zero length extensions, previously this would cause a null
174 pointer dereference
175 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.
176

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

TC
209 - re-work most image file test files that require a library into
210 separate library present/not present files to remove stupidly long
211 conditionals
212
213 - don't treat rubthrough() outside the bounds of the target image as
214 an error.

220Bug fixes:
221
222 - correct documentation of default of raw image interleave read
223 parameter
224 https://rt.cpan.org/Ticket/Display.html?id=42074
225
226 - add raw_ prefix to raw read parameters, though the original names
227 still work.
228
229 - fail the read if an invalid raw_interleave parameter is supplied
230
231 - warn if no interleave or raw_interleave parameter is supplied,
232 since the documented default was wrong, and incompatible with the
233 write format
234
235 - for reading raw images, if raw_storechannels > raw_datachannels,
236 set the extra channels in the image to 0
237
cd476e58
TC
238 - when probing for executables like freetype-config, search for .bat

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

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

c586eb58
TC
284 - add limited tests for Imager::ExtUtils
285
286 - make Imager::ExtUtils->includes use an absolute path, since

289
6b22ba84
TC
290 - re-arrange the POD for Imager::Font::BBox:
291 - mark total_width(), pos_width(), end_offset() obsolete, since
292 they're mostly for backwards compatibility
293 - group width methods and height methods

299Bug fixes:
300
301 - In some cases when an error occurs reading those parts of a JPEG
302 file after the image the scan-line buffer could be freed a second
303 time. In cases where the the error occured while reading the image
304 data it's possible that the buffer could have leaked.
305 Thanks to Gabriel Vasseur for reporting this and help in tracking
306 it down.

308 - the gif_screen_height tag was overriding the screen width and being
309 ignored for the screen height when present.

TC
318Bug fixes:
319
e02d22d2
TC
320 - Possible security issue: The floating point sample path for image
321 based fills had a buffer overflow. This would overwrite the end of
322 a malloc()ed buffer with double precision floats.
323 http://rt.cpan.org/Ticket/Display.html?id=35324
6912d85a 324 CVE-2008-1928
e02d22d2 325
de470892
TC
326 - check that the result of fileno($fh) is defined rather than simply
327 true when read() or write() is supplied with an fh parameter.
328 http://rt.cpan.org/Ticket/Display.html?id=35139
329
330 - i_scale_axis() wasn't checking the result of i_img_new_ch()
331 resulting in a SIGSEGV when attempting to scale an image to a size
332 too large to fit in memory. This is a NULL pointer access issue,
333 not a buffer overflow.
334 Added a check for the failure.
335 scale_calculate() (and hence scale()) will now fail if any of the
336 scale size parameters are a reference.

346===========
347
242d7497
TC
348This release primarily contains changes to improve ease of use -
349rather than you having to convert images to the appropriate number of
350channels, Imager handles it internally. How to handle drawing colors
351and the default combine mode is a thornier problem left for some other
352release.
353

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

356
9b1ec2b8
TC
357 - moved the imtoc.perl code into Imager::Preprocess
358
359 - paste() and rubthrough() now adapt the source image data to the
360 destination, so you can now safely paste/rubthrough from greyscale
361 images to color images or back, or from alpha channel images to
362 noalpha channels or back.
363 https://rt.cpan.org/Ticket/Display.html?id=30908
364
365 - rubthrough() now falls back to pasting when the source doesn't have
366 an alpha channel. This effectively treats the source as having a
367 max alpha channel, the right thing to do.
368 http://rt.cpan.org/Ticket/Display.html?id=29944
369
370 - re-worked most of the area filling code to use a common set of
371 functions when filling.
372 Corrected normal combine mode.
373 Rewrote most of the combine modes to match the way the SVG draft
374 defines them with respect to a translucent source and destination.
375 Added tests for translucent source and destination.
376 Added tests to check 8-bit/sample and double/sample combines work
377 similarly.

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

408 https://bugzilla.redhat.com/show_bug.cgi?id=166254
409 I'm not changing the #! lines of the sample code, since it's sample
410 code, not intended for installation.

413 - some TGA images weren't being detected correctly as TGA images
414 https://rt.cpan.org/Ticket/Display.html?id=32925
415
416 - handling of the left-over bit for 16-bit/pixel TGA images has been
417 changed to match the behaviour of the GIMP. Previously the bit
418 being set was treated as an opaque pixel, but one user reported a
419 problem with loading such an image. I haven't been able to find any
420 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
421 I'll match it's behaviour. See issue 114913 in the GIMP's
422 bugzilla.

432 - the old dynaload code used Mach API functions to load dynamic
433 libraries on Mac OS X. These APIs have been deprecated in OS X
434 10.5 and were causing some build problems.
435 So henceforth Imager uses the dlopen() family of functions, and you
436 will need version 10.3 or later of OS X.

740Imager 0.55 - 16 Dec 2006
741===========
742
743This is primarily a bug fix release.
744
745Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
746
747There is one new feature:
748
749 - the Win32 font driver now supports UTF8 (RT 22166)
750 http://www.cpanforum.com/threads/3276
751 http://rt.cpan.org/Ticket/Display.html?id=22166
752
753Several bugs were fixed:
754
755 - the string() method would not output the string "0"
756 http://rt.cpan.org/Public/Bug/Display.html?id=21770
757
758 - fills.c was failing to compile on Solaris 10 (compiler unknown)
759 http://rt.cpan.org/Public/Bug/Display.html?id=21944
760
761 - the gif_disposal and gif_user_input tags weren't being read from
762 the file correctly
763 http://rt.cpan.org/Public/Bug/Display.html?id=22192
764
765 - gif.c was failing to build under MSVC
766 http://rt.cpan.org/Ticket/Display.html?id=23922
767
768 - in some cases strings passed to the string() method were treated as
769 terminated by NUL (chr 0)
770 http://rt.cpan.org/Public/Bug/Display.html?id=21770
771
772 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
773 that's the default build name for zlib on Win32.
774 http://rt.cpan.org/Ticket/Display.html?id=23064
775
776 - search $Config{incpath} for headers too, which we should have been
777 doing all along.
778
779Win32 font driver fixes:
780
781 - the global descent value from bounding box was the wrong sign
782 http://www.cpanforum.com/threads/3276
783
784 - if the first or last glyph overflowed the left or right side of the
785 advance width they would be clipped
786
787
788Imager 0.54 - 14 Sep 2006
789===========
790
791This is primarily a feature release:
792
793 - a new qtype value 'mixing' has been added to the scale()
794 method. This is faster than 'normal', slower than 'preview'. This
795 is based on the method used by pnmscale, and seems to produce less
796 blurry results than normal.
797 http://rt.cpan.org/Public/Bug/Display.html?id=20677
798
799 - the rubthrough() method can now render onto images with an alpha
800 channel.
801 http://rt.cpan.org/Ticket/Display.html?id=20678
802
803 - the read_multi() method now falls back to calling doing a single
804 image read via the read() method and write_multi() will now fall
805 back to calling write() if a single image is supplied. This means
806 you can simply call the read_multi() or write_multi() functions
807 without having to check if the type is formatted by that method.
808 http://rt.cpan.org/Ticket/Display.html?id=19457
809 http://rt.cpan.org/Ticket/Display.html?id=19458
810
811 - the GIF loop extension can now be written. If you don't have
812 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
813 should upgrade.
814 http://rt.cpan.org/Ticket/Display.html?id=21185
815
816 - getscanline() and setscanline() can now read/write palette index
817 based data from/to the image for paletted images, by setting type to
818 'index'.
819 http://rt.cpan.org/Ticket/Display.html?id=20338
820
821 - we no longer hassle you to disable GIF support
822 http://rt.cpan.org/Ticket/Display.html?id=20687
823
824 - minor documentation fixes
825
826
827Imager 0.53 - 26 Jul 2006
828===========
829
830This is a bugfix release.
831
832Some test code was left in a code path not covered by the test
833suite. A test was added to cover this code path and the test code was
834removed.
835http://rt.cpan.org/Public/Bug/Display.html?id=20705
836
837
838Imager 0.52 - 25 Jul 2006
839===========
840
841This is primarily a feature release, but contains a fair few bug
842fixes, new features:
843
844 - ability to read and write MS Windows ICO and CUR files
845
846 - you can now add file format plugins to support new file formats
847
848 - add POD coverage tests
849
850 - setcolors() and addcolors() now accept color names and so on
851 instead of requiring Imager::Color objects.
852 http://rt.cpan.org/Ticket/Display.html?id=20056
853
854 - flood_fill() can now fill to a specified border color instead of
855 just to the area the same color as the seed.
856 http://rt.cpan.org/Ticket/Display.html?id=19618
857
858
859Bug fixes:
860
861 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
862 calculating the advance width.
863 http://rt.cpan.org/Public/Bug/Display.html?id=20554
864
865 - bounding_box for the T1 driver wasn't including leading and
866 trailing spaces in the bounding box as the other drivers did, it also
867 produced strange results for empty strings or strings containing only
868 spaces
869
870 - when reading CMYK jpeg images they were being transferred to the
871 image object as is, producing a four channel image. It only looked ok
872 due to an old still unfixed Photoshop bug. We now convert from the
873 inverted CMYK that photoshop (and Corel for example) produce into RGB.
874 http://rt.cpan.org/Ticket/Display.html?id=20416
875
876 - reading a CYMK TIFF would result in a 4 channel image, reading any
877 image with more than 4 channels (eg. RGB with 2 alpha channels) would
878 result in an error.
879 http://rt.cpan.org/Ticket/Display.html?id=20415
880
881 - added /usr/local/include to the default include search path, since
882 we were already searching /usr/local/lib for libraries.
883
884And various minor fixes and documentation updates.
885
886
