  <p><a href="https://github.com/Cheesebaron/MonoDroid.CaptureSignature" rel="nofollow">https://github.com/Cheesebaron/MonoDroid.CaptureSignature</a></p>
  
  <p>Its working fine if i save image as png but i want to save it in jpg </p>
  
  <p>I changed Bitmap.CompressFormat.Png to Bitmap.CompressFormat.Jpg</p>
  
  <p>but what i am getting is a black jpg file because the writing is in black </p>
  
  <p>and the background is already black. How can i make image background white?</p>
  
  <p>code i changed </p>
  
  <pre><code>using (var fs = new FileStream(extFileName, FileMode.OpenOrCreate))
  {
    _capture.CanvasBitmap().Compress(Bitmap.CompressFormat.Jpg, 100, fs);
  }
  </code></pre>
  
  <p>Looking for help. Thanks</p>
