Class EdgeTrace

java.lang.Object

imagingbook.common.edges.EdgeTrace

All Implemented Interfaces:

Iterable<Pnt2d.PntInt>

public class EdgeTrace
extends Object
implements Iterable<Pnt2d.PntInt>

Represents a chain of connected edge points (integer pixel coordinates). As is, this could have also be implemented as a generic List but additional properties may be added in a future version.
