Thanks Graham
It took a bit of trial and error, but scaleUnitSquareToSize seems to
do what I want. I ripped out all the transform code and just wrote a
simple override to setFrame for the page view
- (void) setFrame:(NSRect) inFrame
{
NSSize currentSize = [self frame].size;
float scale = inFrame.size.height /
currentSize.height;
[self scaleUnitSquareToSize: NSMakeSize(scale, scale)];
[super setFrame: inFrame];
}
Much easier

Setting a transform in -drawRect: will only apply it to whatever is
drawn within that method. That doesn't include the subviews.
What are you trying to do? If you need to scale the page view then
use -scaleUnitSquareToSize: and adjust the frame. To translate use a
scrollview. To rotate, use -rotateToAngle:
