GrabSprite() public method

Retreive a sprite that has to be drawn within the given destination rectangle, given the bounds of the viewport.

public GrabSprite ( int xFrame, int yFrame, Rectangle dest, Rectangle bounds ) : DirectDrawClippedRect
xFrame	int	Retrieve the Xth horizontal frame.
yFrame	int	Retrieve the Yth vertical frame.
dest	System.Drawing.Rectangle	The destination rectangle for the sprite.
bounds	System.Drawing.Rectangle	The view rectangle bounds.
return	DirectDrawClippedRect
