RotatePage
Page properties, Page manipulation
Description
Used to rotate the page by a multiple of 90 degrees. This will also rotate the co-ordinate system on the page so that it remains the same with respect to the orientation of the page. The rotation is absolute, for example calling the function twice with a parameter of 90 will result in a page rotated by 90 degrees, not 180 degrees.
