10139N/A<para>Return the data for the tile containing the specified coordinates. The

10139N/Adata is returned decompressed and in the native byte- and bit-ordering, but

10139N/Ais otherwise packed as described below. The buffer must be large enough to

10139N/Ahold an entire tile of data. Applications should call the routine <literal>

10139N/ATIFFTileSize</literal> to find out the size in bytes of a tile buffer. The <literal>

10139N/Ax</literal> and <literal>y</literal> parameters are always used by <literal>

10139N/ATIFFReadTile</literal>. The <literal>z</literal> parameter is used if the

10139N/Aimage is deeper than 1 slice (ImageDepth>1). The <literal>sample</literal>

10139N/Aparameter is used only if data is organized in separate planes (PlanarConfiguration=2).

10139N/A</para>

10139N/A<para>The library attempts to hide bit- and byte-ordering differences between

10139N/Athe image and the native machine by converting data to the native machine

10139N/Aorder. Bit reversal is performed if the <literal>FillOrder</literal> tag is

10139N/Aopposite to the native machine bit order. 16- and 32-bit samples are automatically

10139N/Abyte-swapped if the file was written with a byte order opposite to the native

10139N/Amachine byte order.</para>
