Gets image box on a DC and saves it into a BITMAP object.

This function gets image box on the specified device context <em>hdc</em>, and saves the image bits into the BITMAP object pointed to by <em>bmp</em>. The image box begins at <em></em>(x,y), and is <em>w</em> wide and <em>h</em> high. You must make sure that <em>bmp-&gt;bits</em> is big enough to store the image.<p>
