示例1: TIFFWriteEncodedTile
// Encode the supplied data and write it to the
// specified tile. There must be space for the
// data. The function clamps individual writes
// to a tile to the tile size, but does not (and
// can not) check that multiple writes to the same
// tile do not write more than tile size data.
//
// NB: Image length must be setup before writing; this
// interface does not support automatically growing
// the image on each write (as TIFFWriteScanline does).
