DIVE (Direct Interface to Video Extensions)

DIVE is a DLL that provides optimized blitting performance for motion video subsystems and applications that perform rapid screen updates in the OS/2 PM and full-screen environments. Using DIVE functions, applications can either write directly to video memory or use the DIVE blitter to get a high level of screen update performance, image scaling, color space conversion, and bank-switch display support. The DIVE blitter utilizes acceleration hardware when present and applicable to the function being performed.
