I have a couple of small canvases holding some icon images in them which look fine on iPhone. How do I scale the canvas to look appropriate on iPad? ---

If you want to change the height or width or any of the auto-layout constraints on your canvases, use [iOSLayoutConstraint](http://developer.xojo.com/ioslayoutconstraint) to create a reference to the constraint(s) you want to change and then change the property you want, eg the offset. ---

Thanks Jason, I thought that was above my pay grade but it strangely makes sense. Cheers Martin ---
