The Khronos Group, an industry consortium creating open standards to
enable the authoring and acceleration of graphics and dynamic media
on a variety of platforms and devices, has announced the release of
the OpenWF 1.0 standard.
OpenWF is an operating system-independent and hardware-neutral
foundation for building windowing systems and providing display
control functionality in accelerated mobile and embedded devices. It
enables a new degree of portability, acceleration and abstraction for
windowing systems, while adding functionality and features through
close integration with Khronos application APIs (application
programming interface), according to the Khrnonos Gorup. OpenWF acts
as the underlying route to the display for advanced graphics and
multimedia content generated using APIs such as OpenGL ES for
portable 3D graphics, OpenVG for vector graphics acceleration, and
OpenMAX for multimedia.
OpenWF provides two separate but complementary low-level APIs for
composition of content and the configuration of display devices:
OpenWF Composition and OpenWF Display. OpenWF Display enables
portable access to display control hardware for manipulating screen
attributes, while OpenWF Composition allows for layering and
system-wide composition of application content. The two APIs can be
used together or independently, depending on specific platform needs.
OpenWF enables highly-optimized mechanisms to display application
content in a windowing system. By eliminating redundant memory
accesses, consumed memory bandwidth may be reduced by more than half,
resulting in significant power savings, says the Khronos Group.
