14 TIFFFieldReadCount returns the number of values available to be read
15 from the specified TIFF field; that is, the number of arguments that
16 should be supplied to TIFFGetField. For most field types this is a
17 small positive integer, typically 1 or 2, but there are some special
18 values:
19 TIFF_VARIABLE indicates that a variable number of values is possible;
20 then, a uint16_t count argument and a pointer data argument must be
21 supplied to TIFFGetField.
22 TIFF_VARIABLE2 is the same as TIFF_VARIABLE except that the count argu‐
23 ment must have type uint32_t.
24 TIFF_SPP indicates that the number of arguments is equal to the image's
25 number of samples per pixel.
26
27 fip is a field information pointer previously returned by TIFFFind‐
28 Field, TIFFFieldWithTag, or TIFFFieldWithName.

31 TIFFFieldReadCount returns an integer.
