OpenVG™ 是针对诸如Flash和SVG的矢量图形算法库提供底层硬件加速界面的免授权费、跨平台应用程序接口API。OpenVG 现仍处于发展阶段，其初始目标主要面向需要高质量矢量图形算法加速技术的便携手持设备，用以在小屏幕设备上实现动人心弦的用户界面和文本显示效果，并支持硬件加速以在极低的处理器功率级别下实现流畅的交互性能。
The Standard for Vector Graphics Acceleration
OpenVG™ is a royalty-free, cross-platform API that provides a low-level hardware acceleration interface for vector graphics libraries such as Flash and SVG. OpenVG is targeted primarily at handheld devices that require portable acceleration of high-quality vector graphics for compelling user interfaces and text on small screen devices - while enabling hardware acceleration to provide fluidly interactive performance at very low power levels.
OpenVG at a glance
OpenVG 1.0 is an application programming interface (API) for hardware accelerated two-dimensional vector and raster graphics. It provides a device independent and vendor-neutral interface for sophisticated 2D graphical applications, while allowing device manufacturers to provide hardware acceleration on devices ranging from wrist watches to full microprocessor-based desktop and server machines.
OpenVG 1.1, released on December 8th, 2008, adds a Glyph API for hardware accelerated text rendering, full acceleration support for Adobe® Flash® and Flash Lite 3 technologies, and multi-sampled anti-aliasing to the original OpenVG 1.0 specification. The new OpenVG specification is accompanied by an open source reference implementation and a full suite of conformance tests implemented by the Khronos Group.
The Benefits of an Accelerated Vector Graphics API for Small Screen Devices
OpenVG in a Nutshell
Royalty-free open standard API
Low-level 2D vector graphics rendering API
Advanced feature set to enable SVG, Flash, Vector Fonts etc.
Enables smooth evolution towards hardware accelerated vector graphics
Vector graphics are widely used on today's desktop through packages such as Flash and SVG. Handheld devices have an urgent need for the smooth and fluidly scalable 2D that high-quality vector graphics provide to create high-quality user interfaces and ultra-readable text on small displays devices. Existing solutions have significant limitations. OpenVG addresses these limitation and provides additional tangible benefits:
Low Power Consumption - An efficient 3D hardware accelerator reduces power consumption by up to 90% compared to a software engine
Seamless Transition from Software to Hardware - Enables a seamless transition from efficient software rendering to hardware-accelerated high-quality 2D
Scalability - Vector graphics provides easy scalability with high-quality rendering, including anti-aliasing, to different screen sizes without multiple bitmaps
Accelerates Existing Formats -Designed to accelerate existing formats (e.g. Flash, SVG, PDF, Postscript, Vector fonts, etc.)
Games, Screensavers, Mapping, User Interfaces - Fast scalable anti-aliased vector graphics enables advanced user interfaces, mapping applications, games and screensavers
Portable Content - Scalable vector graphics makes it easier to port content across devices and platforms
Royalty Free - A royalty-free, cross platform API facilitate rapid developer adoption and content creation
