Im running XDirectFB and DirectFB in software mode in ARGB mode on hardware where the alpha value in the framebuffer controls the visibility of the graphics plane over an video underlay. Ie, a alpha value of 255 in the framebuffer will make the graphics pixel fully opaque.
My problem is that when running XDirectFB the X applications are invisible. X seems to zero the alpha value. However if I also start another DirectFB application that also creates windows on the primary display and blend the windows, the X applications is seen though the windows. What I dont really understand is the relation between the alpha values in layers(mainly the primary display layer) and the alpha value that is written in /dev/fb and how layers are blended together. Is this up to driver to decide? Please explain this. TIA, Marcus Gustafsson -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-dev" as subject.
