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 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 TIFFSetField.
       TIFF_VARIABLE2  is the same as TIFF_VARIABLE except that the count argument 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 TIFFFindField, 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.
