Invalidates the cached path that is used to render the stroke.

open Any!

open OrientedBoundingBox!

Computes an oriented bounding box of the stroke.

open Path!

open Path!
toPath(width: Float, height: Float, numSample: Int)

GestureStroke(points: ArrayList<GesturePoint!>!)

A constructor that constructs a gesture stroke from a list of gesture points.

Parameters
points ArrayList<GesturePoint!>!:

Public methods

clearPath

Added in API level 4
open fun clearPath(): Unit

Invalidates the cached path that is used to render the stroke.

clone

Added in API level 4
open fun clone(): Any!
Return
Any! a clone of this instance.
Exceptions
java.lang.CloneNotSupportedException if the object's class does not support the Cloneable interface. Subclasses that override the clone method can also throw this exception to indicate that an instance cannot be cloned.

computeOrientedBoundingBox
