Known bugs and suggested enhancements in libpng-1.0.8
1. July 2, 2000 -- BUG -- pnggccrd.c
0: November 3, 2000 -- BUG -- incorrect iCCP chunk is written
The png_read_filter() function has still not been fully converted and
The compression_type byte in the iCCP chunk written by libpng is
usually incorrect.
Status: Fixed in libpng-1.0.9beta1
1. October 12, 2000 -- BUG -- pngtest fails
The three WRITEFILE calls in pngtest.c are incorrect. They must be
changed to read
WRITEFILE((png_FILE_p)png_ptr->io_ptr, data, length, check);
WRITEFILE(io_ptr, near_data, length, check);
WRITEFILE(io_ptr, buf, written, err);
2. August 28, 2000 -- BUG -- pnggccrd.c
The interlacing() function has still not been fully converted and
will not compile under gcc-2.95.2; it is currently ifdef'ed out.
STATUS: Under investigation. Experts on MMX assembler code are
invited to help with the debugging. Note that pngvcrd.c works fine.
STATUS: Fixed in libpng-1.0.9. There were also bugs in pngvcrd.c
which have been fixed. The replacement files are available at the
PNG web site (http://www.libpng.org/pub/png).
