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_tcount 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.
