NAME
_TIFFauxiliary - auxiliary functions
SYNOPSIS
#include <tiffio.h>
uint32_t _TIFFClampDoubleToUInt32(double val)
uint32_t _TIFFMultiply32(TIFF *tif, uint32_t first, uint32_t second,
const char *where)
uint64_t _TIFFMultiply64(TIFF *tif, uint64_t first, uint64_t second,
const char *where)
DESCRIPTION
_TIFFClampDoubleToUInt32() clamps double values into the range of
uint32_t (i.e. 0 .. 0xFFFFFFFF)
_TIFFMultiply32() and _TIFFMultiply64() checks for an integer overflow
of the multiplication result and return the multiplication result or 0
if an overflow would happen. The string where is printed in the error
message in case an overflow happens and can be used to indicate where
the function was called.
