Class Transformer

java.lang.Object

vn.uiza.views.draggablepanel.transformer.Transformer

Direct Known Subclasses:

ScaleTransformer

public abstract class Transformer
extends java.lang.Object

Abstract class created to be implemented by different classes are going to change the size of a view. The most basic one is going to scale the view and the most complex used with VideoView is going to change the size of the view.

The view used in this class has to be contained by a RelativeLayout.

This class also provide information about the size of the view and the position because different Transformer implementations could change the size of the view but not the position, like ScaleTransformer does.
