Constructor Details

#initialize(element, x = 0, y = 0, width = nil, height = nil) ⇒ Use

In a container, Use objects are created indirectly via the RVG::UseConstructors#use method. The x and y arguments can be used to specify an additional translation for the group. The width and height arguments specify a width and height for referenced RVG objects.
