NAME
       TIFFFieldReadCount - Get number of values to be read from field

SYNOPSIS
       #include <tiffio.h>

       int TIFFFieldReadCount(const TIFFField* fip)

DESCRIPTION
       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  sup‐
       plied to TIFFGetField.
       TIFF_VARIABLE2 is the same as TIFF_VARIABLE except that the count argu‐
       ment 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 TIFFFind‐
       Field, TIFFFieldWithTag, or TIFFFieldWithName.

RETURN VALUES
       TIFFFieldReadCount returns an integer.
