Since you've programmed the bes to 1024x768 you must use at least that resolution. Otherwise you'll be downscaling and it's likely that the rectangle won't be visible. > All I want > to do is to use the hardware overlay function of G450 to achieve speed. > Besides, is it the same thing that is mentioned in chip specs of G450 as > 24 + 8 bit mode. 24 bit base image and 8 bit hardware overlay?? No this is different. BES is mainly used for video playback. I'm not sure what the 24+8 mode is normally used for. matroxfb doesn't program the hardware for this mode so you'd have to do it from DirectFB (and hope matroxfb won't reset it back :) Also DirectFB's drawing routines would probably overwrite your overlay data in an instant. Adding a new pixelformat could solve that but then I'm not sure how to decide which part of the pixel we're drawing to... -- Ville Syrj�l� [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-users" as subject.
