src_x - x-coordinate of source pixel to copy from
src_y - y-coordinate of source pixel to copy from src_buffer - name of buffer to copy from, e.g. ImageBuffer() dest_x - x-coordinate of destination pixel to copy to dest_y - y-coordinate of destination pixel to copy to dest_buffer (optional) - name of buffer to copy to, e.g. BackBuffer() |

You can use this command on a locked buffer for a slight speed-up. See LockBuffer.
