Something like this: > CGContextSetShadow(context, shadowOffset, shadowBlur); > CGContextBeginTransparencyLayer(context, NULL); // do your drawing > CGContextEndTransparencyLayer(context); You could get the graphicsPort from > the NSGraphicsContext to call the transperancy layer methods and otherwise > stick to NSGraphics stuff.
