Constructor
The constructor is where the flipbook or the zoom viewport is created. Therefore, it's called once and cannot be omitted.
Both the flipbook and the zoom viewport have independent constructors.
Turn Constructor
Syntax:
$(".magazine").turn([options]);
For example:
$(".magazine").turn({page: 1, acceleration: true, gradients: true});
Zoom Constructor
Syntax:
$(".viewport").zoom(options);
For example:
$(".viewport").zoom({flipbook: $(".viewport")});
