transform

public void transform(android.view.View view,
                      float position)

Description copied from interface: CarouselView.ViewTransformer

Transform a given item view based on position. Usually translate, rotation, alpha, visibility, ... may be altered.

Specified by:

transform in interface CarouselView.ViewTransformer

Overrides:

transform in class ParameterizableViewTransformer

Parameters:

view - Item view

position - For example, 0 for the current center-most item at a stable position; 4 for 4-th item at the right to the current item; -3 for 3-rd item at the left to the current item; 0.1 for the current item with 10% offset right to its stable position.
