Posted 2021-02-24

Converting BitmapSource to Bitmap in C#

private System.Drawing.Bitmap BitmapFromSource(BitmapSource bitmapsource)
 {
     System.Drawing.Bitmap bitmap;
     using (MemoryStream outStream = new MemoryStream())
     {
       BitmapEncoder enc = new BmpBitmapEncoder();
 
       enc.Frames.Add(BitmapFrame.Create(bitmapsource));
       enc.Save(outStream);
       bitmap = new System.Drawing.Bitmap(outStream);
     }
     return bitmap;
 }
