It's a stack. Save pushes, Restore pops. /* Push a copy of the current graphics state onto the graphics state stack. Note that the path is not considered part of the graphics state, and is not saved. */ CG_EXTERN void CGContextSaveGState(CGContextRef c) CG_AVAILABLE_STARTING(__MAC_10_0, __IPHONE_2_0); /* Restore the current graphics state from the one on the top of the graphics state stack, popping the graphics state stack in the process. */ CG_EXTERN void CGContextRestoreGState(CGContextRef c) CG_AVAILABLE_STARTING(__MAC_10_0, __IPHONE_2_0); -- Seth Willits _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
