pathIterator

public PathIterator pathIterator(Transform t,

Description copied from interface: IShape

Returns an iterator over the path described by this shape.

Specified by:

pathIterator in interface IShape

Parameters:

t - if supplied, the points in the path are transformed using this.

flatness - when approximating curved segments with lines, this controls the maximum distance the lines are allowed to deviate from the approximated curve, thus a higher flatness value generally allows for a path with fewer segments.
