title: How to create mirror shape on graphic
body: <p>I have the point list</p>
  
  <pre><code>List&lt;Point&gt; pointList = new List&lt;Point&gt;();
  
  pointList.Add(new Point(0,0));
  pointList.Add(new Point(30,0));
  pointList.Add(new Point(30,-100));
  pointList.Add(new Point(0,-100));
  </code></pre>
  
  <p>Then Draw the line </p>
  
  <pre><code>Pen pen = new Pen(Color.Red,2);
  
  g.Drawline(pen,pointList[0],pointList[1]);
  
  g.Drawline(pen,pointList[3],poin,tList[4]);
  </code></pre>
  
  <p>for this I will get the result of the left image in the link</p>
  
  <p><img src="https://i.stack.imgur.com/IlTk4.png" alt="mirror image"></p>
  
  <p>and If I need to create the mirror to get the result of the right image in the link</p>
  
  <p>is there any method that can mirror the graphic that I draw from pointlist ?</p>
  
  <p>it there something like copy and flip the graphic and compound?</p>
  
  <p>Thank you</p>
