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.
