Is it possible to use DB to invert all the screen colors continuously in real time ?

You might be able to do it by rendering to bitmap 0, copying that into another bitmap, or straight into a memblock, then inverting all the numbers in the memblock and converting it back to a bitmap, then getting that image and pasting it as a sprite over the screen. I don't know how fast this would work, if it even did work.

Just in case I was not clear.
I meant everything on the windows desktop.

I dont know if it is possible to capture the screen and redraw it as negative in real time so maybe it is possible to modify a driver setting.

eg. similar to changing the gamma in display properties ?
