See my question named "QD drawing".
OK. But why does using an NSScroller instead of an NSScrollView make a
difference?
Initially, I was drawing the wave with an NSBezierPath. But this is
painfully slow when the view is "zoomed" out so the entire sound is
visible within the view and the sound file is large.
Did you try to draw the whole lot only once and then use the Quartz
Compositor to scale the image?
With something like NSImage's - (void)drawInRect:(NSRect)dstRect
fromRect:(NSRect)srcRect operation:(NSCompositingOperation)op
fraction:(float)delta
bye. Andreas.
