Type Method

performGammaFade()

Indicates whether the screen saver application should perform a gradual screen fade when it starts and stops the animation.

Declaration

class func performGammaFade() -> Bool

Discussion

This class method allows the screen saver view to select how the desktop visibly transitions to the screen saver view. If this method returns true, the screen will gradually darken before the animation begins. If it returns false, the transition will be immediate. The latter behavior is more appropriate if the screen saver animates a screen shot of the desktop, as is the case for optical lens effects. The default is true.
