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_t 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_t.  (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.
