int TIFFFieldPassCount(const TIFFField* fip)
fip is a field information pointer previously returned by TIFFFindField, TIFFFieldWithTag, or TIFFFieldWithName.
When a
count
is required, it will be of type
uint32
when
TIFFFieldReadCount
reports
TIFF_VARIABLE2,
and of type
uint16
otherwise. (This distinction is critical for use of
TIFFGetField,
but normally not so for use of
TIFFSetField.)
