PS: The WDDM driver is a virtual driver, I use it to maintain pictures and send them to remote clients to display(like RDP). so I must compress the pictures before transmission. When I get the process id of the application, I can compress the pictures belong to the corresponding application to decide compression algorithm in lossy or lossless.
