TIFFReadRawTile \- return an undecoded tile of data from an open TIFF file

.PP
Read the contents of the specified tile into the user-supplied data
buffer\&.
.PP
The value of \fItile\fR 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)\&. \fBTIFFComputeTile\fR
automatically does this when converting an \fIx,y,z,sample\fR
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 \fBTIFFTileSize(3tiff)\fR\&.
.PP
All error messages are directed to the \fBTIFFError(3tiff)\fR
routine\&.
.SH ""
.PP
Returns the actual number of bytes of data that were placed in \fBbuf\fR\&. Returns -1 if an error was encountered\&.
