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.
