* Writes raster data from the given in-memory source buffer into the data sink specified by the
* given source band and region.
*
* <p>
*
* <h3>Source band</h3>
*
* The source band is used to identify the data sink in which this method transfers the sample
* values given in the source buffer. The method does not modify the pixel data of the given
* source band at all.
*
* <p>
*
* <h3>Source buffer</h3>
*
* The first element of the source buffer corresponds to the given <code>sourceOffsetX</code> and
* <code>sourceOffsetY</code> of the source region. These parameters are an offset within the
* band's raster data and <b>not</b> an offset within the source buffer.<br>
* The number of elements in the buffer must be exactly be <code>sourceWidth * sourceHeight</code>
* . The pixel values to be writte are considered to be stored in line-by-line order, so the
* raster X co-ordinate varies faster than the Y.
*
* <p>
*
* <h3>Source region</h3>
*
* The given destination region specified by the <code>sourceOffsetX</code>, <code>sourceOffsetY
* </code>, <code>sourceWidth</code> and <code>sourceHeight</code> parameters is given in the
* source band's raster co-ordinates. These co-ordinates are identical with the destination raster
* co-ordinates since product writers do not support spectral or spatial subsets.
*
* @param sourceBand the source band which identifies the data sink to which to write the sample
* values
* @param regionData the data buffer which provides the sample values to be written
* @param regionX the X-offset in the band's raster co-ordinates
* @param regionY the Y-offset in the band's raster co-ordinates
* @param regionWidth the width of region to be written given in the band's raster co-ordinates
* @param regionHeight the height of region to be written given in the band's raster co-ordinates
* @throws java.io.IOException if an I/O error occurs
* @throws IllegalArgumentException if the number of elements source buffer not equals <code>
* sourceWidth *
* sourceHeight</code> or the source region is out of the band's
* raster
* @see Band#getRasterWidth()
* @see Band#getRasterHeight()
