isDoubleSided
A Boolean value that indicates whether content appears on the back of pages.
Declaration
var isDoubleSided: Bool { get set }Discussion
The default value for this property is false.
If the back of pages has no content (the value is false), then the content on the front of the page will partially show through to the back when turning pages.
If the spine is located in the middle, the value must be true. Setting it to false with the spine located in the middle raises an exception.
