  +--edu.berkeley.guir.lib.satin.objects.ViewHandler

All Implemented Interfaces:

Cloneable, SatinConstants, Serializable

public class ViewHandler

extends Object

implements SatinConstants, Serializable, Cloneable

Handles the view portions of GraphicalObjects.

Everything in here is in local coordinates. That is, (0,0) is defined to be the top-left corner of the GraphicalObject, without any transforms applied anywhere.
