8e92cd51c6 [libpng16] Bump version to 1.6.0beta16 2012-03-02 14:04:36 -06:00
Glenn Randers-Pehrson
363387c9c0 [libpng16] Imported from libpng-1.6.0beta15.tar v1.6.0beta15 2012-03-02 13:45:00 -06:00

6f237b6bf0 [libpng16] Remove whitespace at end of lines 2012-03-02 13:20:52 -06:00

a0ddf0b5f2 [libpng16] Minor update to pngstest.c, chmod 755 gentests.sh 2012-03-02 06:56:33 -06:00

5541ea8aaf [libpng16] Relocated declarations of index and padding in new index-checking 
code.
 2012-03-01 22:18:09 -06:00
John Bowler
cf49919686 [libpng16] Fixed some bugs in ICC profile writing. The code should now accept 
all potentially valid ICC profiles and reject obviously invalid ones.
It now uses png_error() to do so rather than casually writing a PNG
without the necessary color data.
 2012-03-01 21:54:07 -06:00
Glenn Randers-Pehrson
363ae65e2b [libpng16] Added tests for invalid palette index while reading and writing 
(work in progress, the latter isn't finished).

cb129a6234 [libpng16] Improved pngstest fine tuning of error numbers, new test file 
generator.  The generator generates images that test the full range of sample
values, allow the error numbers in pngstest to be tuned and checked.  makepng
also allows generation of images with extra chunks, although this is
still work-in-progress.

dee7577330 [libpng16] Added PNG_IMAGE_FLAG_FAST for the benefit of applications that 
store intermediate files, or intermediate in-memory data, while processing
image data with the simplified API.  The option makes the files larger
but faster to write and read.  pngstest now uses this by default; this
can be disabled with the --slow option.

1c25b9b06b [libpng16] Fixed transparent pixel and 16-bit rgb tests in pngstest and removed

Glenn Randers-Pehrson
4690b89eaa [libpng16] Added PNG_SAFE_LIMITS feature to pnglibconf.dfa, pngpriv.h, and new pngusr.dfa 
to reset the user limits to safe ones if PNG_SAFE_LIMITS is defined.
To enable, use CPPFLAGS=-DPNG_SAFE_LIMITS on the configure command
or put #define PNG_SAFE_LIMITS_SUPPORTED in pnglibconf.h.prebuilt.
(Reverted previous implementation of PNG_SECURE.)

bce7988230 [libpng16] Fixed fixed/float API export conditionals. 1) If FIXED_POINT or 
FLOATING_POINT options were switched off, png.h ended up with lone ';'
    characters.  This is not valid ANSI-C outside a function.  The ';'
    characters have been moved inside the definition of PNG_FP_EXPORT and
    PNG_FIXED_EXPORT. 2) If either option was switched off, the declaration
    of the corresponding functions were completely omitted, even though some
    of them are still used internally.  The result is still valid, but
    produces warnings from gcc with some warning options (including -Wall). The
    fix is to cause png.h to declare the functions with PNG_INTERNAL_FUNCTION
    when png.h is included from pngpriv.h.

Fixed a memory overwrite bug in simplified read of RGB PNG with
non-linear gamma Also bugs in the error checking in pngread.c and changed
quite a lot of the checks in pngstest.c to be correct; either correctly
written or not over-optimistic.  The pngstest changes are insufficient to
allow all possible RGB transforms to be passed; pngstest cmppixel needs
to be rewritten to make it clearer which errors it allows and then changed
to permit known inaccuracies.

aa725a375c [libpng16] Corrected estimate of error in libpng png_set_rgb_to_gray API. 
The API is extremely inaccurate for sRGB conversions because it uses an 8-bit
intermediate linear value and it does not use the sRGB transform, so it
suffers from the known instability in gamma transforms for values close
to 0 (see Poynton).  The net result is that the calculation has a maximum
error of 14.99/255; 0.5/255^(1/2.2).  pngstest now uses 15 for the
permitted 8-bit error. This may still not be enough because of arithmetic
error.
