  • Clones a portion of that Bitmap.

  • Draws the cloned portion to the screen.


private void Clone_Example2(PaintEventArgs e)
{

    // Create a Bitmap object from a file.
    Bitmap myBitmap = new Bitmap("Grapes.jpg");

    // Clone a portion of the Bitmap object.
    RectangleF cloneRect = new RectangleF(0, 0, 100, 100);
    System.Drawing.Imaging.PixelFormat format =
        myBitmap.PixelFormat;
    Bitmap cloneBitmap = myBitmap.Clone(cloneRect, format);

    // Draw the cloned portion of the Bitmap object.
    e.Graphics.DrawImage(cloneBitmap, 0, 0);
