OpenWF
Encyclopedia
OpenWF is a royalty-free, cross-platform API
that provides a low-level hardware abstraction interface for composited windowing systems to make use of composition and display hardware. OpenWF is targeted primarily at handheld devices that require portable acceleration of composition whilst minimizing memory bandwidth usage and power levels. OpenWF is managed by the non-profit

The OpenWF consists of two specifications.
- OpenWF Composition for accelerating composition of multimedia and graphics content. OpenWF Composition includes the ability to autonomously composite streams of pixel data to on-screen and off-screen destinations.
- OpenWF Display for managing display control hardware. OpenWF Display includes the ability to perform mode-setting on internal and external displays as well as discovery and querying of newly connected displays. Direct pipeline control allows composition of images and streams.
Specification versions
- OpenWF Composition 1.0 Specification was released November 9, 2009.
- OpenWF Display 1.0 Specification was released November 9, 2009.
