Zooming
By default, users can zoom in or out to view pages by just pointing to the page to zoom and clicking the mouse. You can provide additional zooming capabilities, including allowing users to zoom to a specific percentage, to view the whole page or a dimension of the page (such as the entire page width), and to zoom using a button or another control. If you prefer, you can prevent users from zooming using the mouse, and just let them zoom using the controls and options you provide.
For instructions for setting up and providing zoom capabilities, see Scaling the Preview Page.
