<div class="markdown level1 summary"><p>Returns the next code-block in the current tile for the specified
component, as a copy (see below). The order in which code-blocks are
returned is not specified. However each code-block is returned only
once and all code-blocks will be returned if the method is called 'N'
times, where 'N' is the number of code-blocks in the tile. After all
the code-blocks have been returned for the current tile calls to this
method will return 'null'.</p>
<pre><code>       &lt;p&gt;When changing the current tile (through 'setTile()' or 'nextTile()')
       this method will always return the first code-block, as if this method
       was never called before for the new current tile.&lt;/p&gt;&lt;p&gt;The data returned by this method is always a copy of the internal
       data of this object, if any, and it can be modified &quot;in place&quot; without
       any problems after being returned. The 'offset' of the returned data is
       0, and the 'scanw' is the same as the code-block width. See the
       'CBlkWTData' class.&lt;/p&gt;&lt;p&gt;The 'ulx' and 'uly' members of the returned 'CBlkWTData' object
       contain the coordinates of the top-left corner of the block, with
       respect to the tile, not the subband.&lt;/p&gt;
