<div class="markdown level1 summary"><p>Returns, in the blk argument, a block of image data containing the
specifed rectangular area, in the specified component. The data is
returned, as a reference to the internal data, if any, instead of as a
copy, therefore the returned data should not be modified.</p>
<pre><code>       &lt;p&gt;The rectangular area to return is specified by the 'ulx', 'uly', 'w'
       and 'h' members of the 'blk' argument, relative to the current
       tile. These members are not modified by this method. The 'offset' and
       'scanw' of the returned data can be arbitrary. See the 'DataBlk'
       class.&lt;/p&gt;

       &lt;p&gt;This method, in general, is more efficient than the 'getCompData()'
       method since it may not copy the data. However if the array of returned
       data is to be modified by the caller then the other method is probably
       preferable.&lt;/p&gt;

       &lt;p&gt;If the data array in &lt;tt&gt;blk&lt;/tt&gt; is &lt;tt&gt;null&lt;/tt&gt;, then a new one
       is created if necessary. The implementation of this interface may
       choose to return the same array or a new one, depending on what is more
       efficient. Therefore, the data array in &lt;tt&gt;blk&lt;/tt&gt; prior to the
       method call should not be considered to contain the returned data, a
       new array may have been created. Instead, get the array from
       &lt;tt&gt;blk&lt;/tt&gt; after the method has returned.&lt;/p&gt;

       &lt;p&gt;The returned data may have its 'progressive' attribute set. In this
       case the returned data is only an approximation of the &quot;final&quot;
       data.&lt;/p&gt;
