Accelerating Color Space Conversion

Indigo2 IMPACT systems provide accelerated color space conversions and device-specific color matching.

Linear color space conversion. Use the color matrix extension to handle linear color space conversion, such as CMY to RGB, in hardware. This extension is also useful for reassigning or duplicating components. See "The Color Matrix Extension" for more information.
Non-linear color space conversions. Use the 3D and 4D texture extension for color conversion (for example, RGBA to CMYK). Using the glPixelTexGenSGIX() command, you can direct pixels into the lookup table and get other pixels out. Performance has been optimized.
