TIFFFieldReadCount - Get number of values to be read from field
#include <tiffio.h>
int TIFFFieldReadCount(const TIFFField* fip)
TIFFFieldReadCount returns the number of values available
to be read from the specified TIFF field; that is, the number of arguments
that should be supplied to TIFFGetField. For most field types this is
a small positive integer, typically 1 or 2, but there are some special
values:
TIFF_VARIABLE indicates that a variable number of values is possible;
then, a uint16 count argument and a pointer data
argument must be supplied to TIFFGetField.
TIFF_VARIABLE2 is the same as TIFF_VARIABLE except that the
count argument must have type uint32.
TIFF_SPP indicates that the number of arguments is equal to the image's
number of samples per pixel.
fip is a field information pointer previously returned by
TIFFFindField, TIFFFieldWithTag, or TIFFFieldWithName.
TIFFFieldReadCount returns an integer.
