Fixed point APIs are now supported throughout (no missing APIs). Internal fixed point arithmetic support exists for all internal floating point operations. sCAL validates the floating point strings it is passed. Safe, albeit rudimentary, Watcom support is provided by PNG_API_RULE==2 Two new APIs exist to get the number of passes without turning on the PNG_INTERLACE transform and to get the number of rows in the current pass. A new test program, pngvalid.c, validates the gamma code. Errors in the 16 bit gamma correction (overflows) have been corrected. cHRM chunk testing is done consistently (previously the floating point API bypassed it, because the test really didn't work on FP, now the test is performed on the actual values to be stored in the PNG file so it works in the FP case too.) Most floating point APIs now simply call the fixed point APIs after converting the values to the fixed point form used in the PNG file. The standard headers no longer include zlib.h, which is currently only required for pngstruct.h and can therefore be internal. (Patches by John Bowler)

where it is not appropriate. If mainprog->jmpbuf is used by setjmp, then png_longjmp cannot be used. Reversed patch to remove error handler when the jmp_buf is stored in the main program structure, not the png_struct. The error handler is needed because the default handler in libpng will always use the jmp_buf in the library control structure; this is never set. The gregbook code is a useful example because, even though it uses setjmp/longjmp, it shows how error handling can be implemented using control mechanisms not directly supported by libpng. The technique will work correctly with mechanisms such as Microsoft Structure Exceptions or C++ exceptions (compiler willing - note that gcc does not by default support interworking of C and C++ error handling.)
