TIFFFieldWriteCount(3TIFF)			    TIFFFieldWriteCount(3TIFF)

NAME
       TIFFFieldWriteCount - Get number	of values to be	written	to field

SYNOPSIS
       #include	<tiffio.h>

       int TIFFFieldWriteCount(const TIFFField*	fip)

DESCRIPTION
       TIFFFieldWriteCount returns the number of values	to be written into the
       specified TIFF field; that is, the number of arguments that  should  be
       supplied	 to  TIFFSetField.  For	most field types this is a small posi-
       tive 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	TIFFSetField.
       TIFF_VARIABLE2 is the same as TIFF_VARIABLE except that the count argu-
       ment  must  have	 type uint32.  (On most	modern machines, this makes no
       practical difference, and the count argument can	simply be  an  int  in
       either case.)
       TIFF_SPP	 indicates  that  the number of	arguments must be equal	to the
       image's number of samples per pixel.

       fip is a	field information pointer  previously  returned	 by  TIFFFind-
       Field, TIFFFieldWithTag,	or TIFFFieldWithName.

       For  most  field	 types,	 TIFFFieldWriteCount returns the same value as
       TIFFFieldReadCount, but there are some exceptions.

RETURN VALUES
       TIFFFieldWriteCount returns an integer.
