Hi,

we are experimenting with retrieving image informations out of an excel file by using infragistics (InfragisticsWPF4.Documents.Excel.v11.2). We are trying to get an image (i.e. a thumbnail) out of an excel file and this is what we have so far:

private BitmapImage GetImage(WorksheetShape shape) { 
  if (shape is WorksheetImage)
  {
    WorksheetImage img = shape as WorksheetImage;
    using(MemoryStream ms = new MemoryStream())
    {
      img.Image.Save(ms, ImageFormat.Png);
      BitmapImage result = new BitmapImage();
      result.BeginInit();
      result.StreamSource = new MemoryStream(ms.ToArray());
      result.EndInit();
      return result;
    }
  } else if (shape is WorksheetChart) {
     //?? 
  }
} 

As a next step, we would like to extract also chart thumbnails. Is that possible?

Cheers
