First click Options select a device, then click Connect in order to connect to the DirectDraw system. Create one or more surfaces by clicking the Create button and selecting the desired capabilities. Note that an error appears in the message list if creation was not successful.
Select a surface from the drop-down list and manipulate it by using the various buttons. Choose Blt in order to blit from one surface to another using various flags.
