Dear Sirs, Has anybody written a X windows driver that converts 8 bit pseudocolor visuals into 24 trucolor?
This is the problem "what we need is having two different pseudo color 8 bits visuals, we will call "standard" and "underlay". in both visuals we have several windows and colormaps and we have a root window. But in the "standard" visual" we would have a special (fixed) transparency color index in each colormap, that allows to see the underlay visual windows below: for instance suppose i create window A in the underlay visual, and do some drawings inside : nothing appears on the screen. now i create another window B in the normal visual, and paint its background with the transparency color ; if part of the B window rectangle intersects the A window rectangle, i can see the drawings in the intersection. All of this is standard X11 behaviour. The colormaps in both visual can be changed in real time by the application. That's why the problem is complicated and prevents from using directly the hardware. But those changes are not done very often and we might accept a software palette in the two visuals, that maps pseudocolors to tru colors. that's why i'm confident a solution might exists with ony software changes in the driver or X server."
