Title: A Universal Gamma Control
Post by: Calin Leafshade on Wed 16/02/2011 22:15:26

Ok so AGS has a Game.SetGamma() function but this only works in DirectDraw in full screen so can anyone think of a way (internally or using a plugin) to increase/decrease brightness or gamma in an AGS game.

My thoughts:

Direct Draw:
AGS gives you direct access to the screen array in DD so it's pretty easy to alter the values for brightness. Although its probably not that fast.

D3D:
Draw a white primitive over the screen in additive mode.

Any other suggestions are welcome and encouraged.

Any special reason not to use D3D's own SetGammaRamp method?

Not fullscreen compatible.

EDIT No wait, *only* full screen compatible
