Read the contents of the specified tile into the (user supplied) data buffer.
Note that the value of
tile
is a ``raw tile number.'' That is, the caller must take into account whether
or not the data is organized in separate planes (PlanarConfiguration=2).
TIFFComputeTile
automatically does this when converting an (x,y,z,sample) coordinate quadruple
to a tile number. To read a full tile of data the data buffer should typically
be at least as large as the value returned by
TIFFTileSize.
RETURN VALUES
The actual number of bytes of data that were placed in
buf
is returned;
TIFFReadEncodedTile
returns -1 if an error was encountered.
DIAGNOSTICS
All error messages are directed to the
TIFFError(3TIFF)
routine.
