<H2>DESCRIPTION</H2>
|
||
|
|
|
||
|
|
Read the contents of the specified tile into the
|
||
|
|
(user supplied) data buffer.
|
||
|
|
Note that the value of
|
||
|
|
<I>tile</I>
|
||
|
|
|
||
|
|
is a ``raw tile number.''
|
||
|
|
That is, the caller must take into account whether or not the
|
||
|
|
data is organized in separate planes (<I>PlanarConfiguration</I>=2).
|
||
|
|
|
||
|
|
<I>TIFFComputeTile</I>
|
||
|
|
|
||
|
|
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
|
||
|
|
<I>TIFFTileSize</I>.

<H2>RETURN VALUES</H2>
|
||
|
|

|
|
The actual number of bytes of data that were placed in
|
||
|
|
<I>buf</I>
|
||
|
|
|
||
|
|
is returned;
|
||
|
|
<I>TIFFReadEncodedTile</I>
|
||
|
|
|
||
|
|
returns -1 if an error was encountered.
