The fillrect was the simplest to implement. I agree that the others will be much higher value. In DirectFB there are a set of benchmarks that run through all of the different drawing types including filled rectangles. That is what I am using as my baseline.I don't know DirectFB. I am not sure if the DirectFB uses the frame buffer acceleration or its own.
DirectFB has it's own low level gfx drivers. It can use fbdev for mode switching but that's all. In fact there is no way to call fbdev accel code from userspace. -- Ville Syrjälä syrjala@sci.fi http://www.sci.fi/~syrjala/ ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
