NAME

SYNOPSIS

9       #include <tiffio.h>
10
11       int TIFFFieldWriteCount(const TIFFField* fip)

DESCRIPTION

14       TIFFFieldWriteCount returns the number of values to be written into the
15       specified TIFF field; that is, the number of arguments that  should  be
16       supplied  to  TIFFSetField.  For most field types this is a small posi‐
17       tive integer, typically 1 or 2, but there are some special values:
18       TIFF_VARIABLE indicates that a variable number of values  is  possible;
19       then,  a uint16 count argument and a pointer data argument must be sup‐
20       plied to TIFFSetField.
21       TIFF_VARIABLE2 is the same as TIFF_VARIABLE except that the count argu‐
22       ment  must  have  type uint32.  (On most modern machines, this makes no
23       practical difference, and the count argument can simply be  an  int  in
24       either case.)
25       TIFF_SPP  indicates  that  the number of arguments must be equal to the
26       image's number of samples per pixel.
27
28       fip is a field information pointer  previously  returned  by  TIFFFind‐
29       Field, TIFFFieldWithTag, or TIFFFieldWithName.
30
31       For  most  field  types,  TIFFFieldWriteCount returns the same value as
32       TIFFFieldReadCount, but there are some exceptions.

RETURN VALUES

35       TIFFFieldWriteCount returns an integer.
