TIFFFieldReadCount(3TIFF) TIFFFieldReadCount(3TIFF) NAME TIFFFieldReadCount - Get number of values to be read from field SYNOPSIS #include <tiffio.h> int TIFFFieldReadCount(const TIFFField* fip) DESCRIPTION TIFFFieldReadCount returns the number of values available to be read from the specified TIFF field; that is, the number of arguments that should be supplied to TIFFGetField. 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 TIFFGetField. TIFF_VARIABLE2 is the same as TIFF_VARIABLE except that the count argument must have type uint32. TIFF_SPP indicates that the number of arguments is equal to the image's number of samples per pixel. fip is a field information pointer previously returned by TIFFFindField, TIFFFieldWithTag, or TIFFFieldWithName. RETURN VALUES TIFFFieldReadCount returns an integer. SEE ALSO libtiff(3TIFF), Libtiff library home page: http://www.remotesensing.org/libtiff/ libtiff July 26, 2012 TIFFFieldReadCount(3TIFF)
