Class RMPathOffsetter

java.lang.Object

com.inductiveautomation.rm.graphics.RMPathOffsetter

public class RMPathOffsetter
extends java.lang.Object

Offset path - a path that follows the curvature of the input path but is located a constant distance away from the curve.

Mathematically, the offset path is the path defined by tracing the normal to the curve, scaled by d, along the entire path.
