       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
       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.
