9 available due to a problem with the %formats tie
10
11 - handle dependent libraries correctly (eg -lpng requiring -lz) in
12 the code run phase of library probing.

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

31 - moved the PNG file handling code into a sub-module in preparation
32 for separate distribution.

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

145Bug fixes:
146
147 - the conv filter now enforces that the sum of the coefficients is
148 non-zero. Also, rather than skipping pixels off the edge off the
149 edge of the image, the closest edge pixel is used. Previously
150 dividing by the zero sum of coefficients could cause invalid
151 results or runtime exceptions.
152 Thanks to David Cantrell's Alpha-NetBSD CPAN test box for revealing
153 this bug.

160 - release image row and comments memory on all error returns in gif
161 reader

164 pointer dereference
165 Thanks to Krzysztof Wojtaƛ for the test data and fix for this.

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

213 parameter
214 https://rt.cpan.org/Ticket/Display.html?id=42074
215
216 - add raw_ prefix to raw read parameters, though the original names
217 still work.
218
219 - fail the read if an invalid raw_interleave parameter is supplied
220
221 - warn if no interleave or raw_interleave parameter is supplied,
222 since the documented default was wrong, and incompatible with the
223 write format

225 - for reading raw images, if raw_storechannels > raw_datachannels,
226 set the extra channels in the image to 0

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

280 - re-arrange the POD for Imager::Font::BBox:
281 - mark total_width(), pos_width(), end_offset() obsolete, since
282 they're mostly for backwards compatibility

289Bug fixes:
290
291 - In some cases when an error occurs reading those parts of a JPEG
292 file after the image the scan-line buffer could be freed a second
293 time. In cases where the the error occured while reading the image
294 data it's possible that the buffer could have leaked.
295 Thanks to Gabriel Vasseur for reporting this and help in tracking
296 it down.

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

e02d22d2 315
de470892
TC
316 - check that the result of fileno($fh) is defined rather than simply
317 true when read() or write() is supplied with an fh parameter.
318 http://rt.cpan.org/Ticket/Display.html?id=35139
319
320 - i_scale_axis() wasn't checking the result of i_img_new_ch()
321 resulting in a SIGSEGV when attempting to scale an image to a size
322 too large to fit in memory. This is a NULL pointer access issue,
323 not a buffer overflow.
324 Added a check for the failure.
325 scale_calculate() (and hence scale()) will now fail if any of the
326 scale size parameters are a reference.

TC
338This release primarily contains changes to improve ease of use -
339rather than you having to convert images to the appropriate number of
340channels, Imager handles it internally. How to handle drawing colors
341and the default combine mode is a thornier problem left for some other
342release.
343

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

TC
347 - moved the imtoc.perl code into Imager::Preprocess
348
349 - paste() and rubthrough() now adapt the source image data to the
350 destination, so you can now safely paste/rubthrough from greyscale
351 images to color images or back, or from alpha channel images to
352 noalpha channels or back.
353 https://rt.cpan.org/Ticket/Display.html?id=30908
354
355 - rubthrough() now falls back to pasting when the source doesn't have
356 an alpha channel. This effectively treats the source as having a
357 max alpha channel, the right thing to do.
358 http://rt.cpan.org/Ticket/Display.html?id=29944
359
360 - re-worked most of the area filling code to use a common set of
361 functions when filling.
362 Corrected normal combine mode.
363 Rewrote most of the combine modes to match the way the SVG draft
364 defines them with respect to a translucent source and destination.
365 Added tests for translucent source and destination.
366 Added tests to check 8-bit/sample and double/sample combines work
367 similarly.

391 - mixing qtype scaling now sets all channels of a pixel to zero if

403 - some TGA images weren't being detected correctly as TGA images
404 https://rt.cpan.org/Ticket/Display.html?id=32925
405
406 - handling of the left-over bit for 16-bit/pixel TGA images has been
407 changed to match the behaviour of the GIMP. Previously the bit
408 being set was treated as an opaque pixel, but one user reported a
409 problem with loading such an image. I haven't been able to find any
410 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
411 I'll match it's behaviour. See issue 114913 in the GIMP's
412 bugzilla.

422 - the old dynaload code used Mach API functions to load dynamic
423 libraries on Mac OS X. These APIs have been deprecated in OS X
424 10.5 and were causing some build problems.
425 So henceforth Imager uses the dlopen() family of functions, and you
426 will need version 10.3 or later of OS X.

730Imager 0.55 - 16 Dec 2006
731===========
732
733This is primarily a bug fix release.
734
735Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
736
737There is one new feature:
738
739 - the Win32 font driver now supports UTF8 (RT 22166)
740 http://www.cpanforum.com/threads/3276
741 http://rt.cpan.org/Ticket/Display.html?id=22166
742
743Several bugs were fixed:
744
745 - the string() method would not output the string "0"
746 http://rt.cpan.org/Public/Bug/Display.html?id=21770
747
748 - fills.c was failing to compile on Solaris 10 (compiler unknown)
749 http://rt.cpan.org/Public/Bug/Display.html?id=21944
750
751 - the gif_disposal and gif_user_input tags weren't being read from
752 the file correctly
753 http://rt.cpan.org/Public/Bug/Display.html?id=22192
754
755 - gif.c was failing to build under MSVC
756 http://rt.cpan.org/Ticket/Display.html?id=23922
757
758 - in some cases strings passed to the string() method were treated as
759 terminated by NUL (chr 0)
760 http://rt.cpan.org/Public/Bug/Display.html?id=21770
761
762 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
763 that's the default build name for zlib on Win32.
764 http://rt.cpan.org/Ticket/Display.html?id=23064
765
766 - search $Config{incpath} for headers too, which we should have been
767 doing all along.
768
769Win32 font driver fixes:
770
771 - the global descent value from bounding box was the wrong sign
772 http://www.cpanforum.com/threads/3276
773
774 - if the first or last glyph overflowed the left or right side of the
775 advance width they would be clipped
776
777
778Imager 0.54 - 14 Sep 2006
779===========
780
781This is primarily a feature release:
782
783 - a new qtype value 'mixing' has been added to the scale()
784 method. This is faster than 'normal', slower than 'preview'. This
785 is based on the method used by pnmscale, and seems to produce less
786 blurry results than normal.
787 http://rt.cpan.org/Public/Bug/Display.html?id=20677
788
789 - the rubthrough() method can now render onto images with an alpha
790 channel.
791 http://rt.cpan.org/Ticket/Display.html?id=20678
792
793 - the read_multi() method now falls back to calling doing a single
794 image read via the read() method and write_multi() will now fall
795 back to calling write() if a single image is supplied. This means
796 you can simply call the read_multi() or write_multi() functions
797 without having to check if the type is formatted by that method.
798 http://rt.cpan.org/Ticket/Display.html?id=19457
799 http://rt.cpan.org/Ticket/Display.html?id=19458
800
801 - the GIF loop extension can now be written. If you don't have
802 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
803 should upgrade.
804 http://rt.cpan.org/Ticket/Display.html?id=21185
805
806 - getscanline() and setscanline() can now read/write palette index
807 based data from/to the image for paletted images, by setting type to
808 'index'.
809 http://rt.cpan.org/Ticket/Display.html?id=20338
810
811 - we no longer hassle you to disable GIF support
812 http://rt.cpan.org/Ticket/Display.html?id=20687
813
814 - minor documentation fixes
815
816
817Imager 0.53 - 26 Jul 2006
818===========
819
820This is a bugfix release.
821
822Some test code was left in a code path not covered by the test
823suite. A test was added to cover this code path and the test code was
824removed.
825http://rt.cpan.org/Public/Bug/Display.html?id=20705
826
827
828Imager 0.52 - 25 Jul 2006
829===========
830
831This is primarily a feature release, but contains a fair few bug
832fixes, new features:
833
834 - ability to read and write MS Windows ICO and CUR files
835
836 - you can now add file format plugins to support new file formats
837
838 - add POD coverage tests
839
840 - setcolors() and addcolors() now accept color names and so on
841 instead of requiring Imager::Color objects.
842 http://rt.cpan.org/Ticket/Display.html?id=20056
843
844 - flood_fill() can now fill to a specified border color instead of
845 just to the area the same color as the seed.
846 http://rt.cpan.org/Ticket/Display.html?id=19618
847
848
849Bug fixes:
850
851 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
852 calculating the advance width.
853 http://rt.cpan.org/Public/Bug/Display.html?id=20554
854
855 - bounding_box for the T1 driver wasn't including leading and
856 trailing spaces in the bounding box as the other drivers did, it also
857 produced strange results for empty strings or strings containing only
858 spaces
859
860 - when reading CMYK jpeg images they were being transferred to the
861 image object as is, producing a four channel image. It only looked ok
862 due to an old still unfixed Photoshop bug. We now convert from the
863 inverted CMYK that photoshop (and Corel for example) produce into RGB.
864 http://rt.cpan.org/Ticket/Display.html?id=20416
865
866 - reading a CYMK TIFF would result in a 4 channel image, reading any
867 image with more than 4 channels (eg. RGB with 2 alpha channels) would
868 result in an error.
869 http://rt.cpan.org/Ticket/Display.html?id=20415
870
871 - added /usr/local/include to the default include search path, since
872 we were already searching /usr/local/lib for libraries.
873
874And various minor fixes and documentation updates.
875
876
877Imager 0.51 - 23 Apr 2006
