title: DotSpatial: Convert a Polygon Feature to System.Drawing.Region
body: <p>I want to paint a Polygon region with a color. </p>
  
  <p>I know I can use <code>Symbolizer</code> to do this but I want that region to blink (change it's color in a timer) and using <code>symbolizer</code> seems to be slow for this purpose. </p>
  
  <p>I'm already using <code>Map.OnPaint</code> event to draw a colored image of a point (in a <code>PointLayer</code>). </p>
  
  <p>So how can I Convert a Polygon Feature (in a <code>PolygonLayer</code>) to <code>System.Drawing.Region</code> so I can use methods in Graphics class to paint that region? </p>
  
  <p>Thanks in advance.</p>
