TIFFVSetField is functionally equivalent to TIFFSetField except that it takes a pointer to a variable argument list. TIFFVSetField is useful for writing routines that are layered on top of the functionality provided by TIFFSetField .
The tags understood by libtiff , the number of parameter values, and the expected types for the parameter values are shown below. The data types are: char* is null-terminated string and corresponds to the ASCII data type; uint16 is an unsigned 16-bit value; uint32 is an unsigned 32-bit value; uint16* is an array of unsigned 16-bit values. void* is an array of data values of unspecified type. Consult the TIFF specification for information on the meaning of each tag.

\(dd If SamplesPerPixel is one, then a single array is passed; otherwise three arrays should be passed. * The contents of this field are quite complex. See "The ICC Profile Format Specification" , Annex B.3 "Embedding ICC Profiles in TIFF Files" (available at http://www.color.org) for an explanation.
%s: Cannot modify tag "%s" while writing. Data has already been written to the file, so the specified tag's value can not be changed. This restriction is applied to all tags that affect the format of written data.
%d: Bad value for "%s". An invalid value was supplied for the named tag.
