      • PathMeasure

        public PathMeasure()

      • PathMeasure

        public PathMeasure​(Path path)
        Initialize the pathmeasure with the specified path. The parts of the path that are needed are copied, so the client is free to modify/delete the path after this call.

      • PathMeasure

        public PathMeasure​(Path path,
                   boolean forceClosed)
        Initialize the pathmeasure with the specified path. The parts of the path that are needed are copied, so the client is free to modify/delete the path after this call.

      • PathMeasure

        public PathMeasure​(Path path,
                   boolean forceClosed,
                   float resScale)

        Initialize the pathmeasure with the specified path. The parts of the path that are needed are copied, so the client is free to modify/delete the path after this call.

        resScale controls the precision of the measure. values > 1 increase the precision (and possible slow down the computation).

        Reset the pathmeasure with the specified path. The parts of the path that are needed are copied, so the client is free to modify/delete the path after this call.

      • getLength

        public float getLength()
        Return the total length of the current contour, or 0 if no path is associated (e.g. resetPath(null))

      • getPosition

        @Nullable
public @Nullable io.github.humbleui.types.Point getPosition​(float distance)
        Pins distance to 0 <= distance <= getLength(), and then computes the corresponding position.

        @Nullable
public @Nullable io.github.humbleui.types.Point getTangent​(float distance)
        Pins distance to 0 <= distance <= getLength(), and then computes the corresponding tangent.
        Returns:
        null if there is no path, or a zero-length path was specified.

      • getRSXform

        @Nullable
public @Nullable RSXform getRSXform​(float distance)
        Pins distance to 0 <= distance <= getLength(), and then computes the corresponding RSXform.
        Returns:
        null if there is no path, or a zero-length path was specified.

        @Nullable
public @Nullable Matrix33 getMatrix​(float distance,
                                    boolean getPosition,
                                    boolean getTangent)

        Given a start and stop distance, return in dst the intervening segment(s). If the segment is zero-length, return false, else return true. startD and stopD are pinned to legal values (0..getLength()). If startD > stopD then return false (and leave dst untouched). Begin the segment with a moveTo if startWithMoveTo is true

        Overrides:
        isClosed in class Managed
        Returns:
        true if the current contour is closed.

      • nextContour

        public boolean nextContour()
        Move to the next contour in the path. Return true if one exists, or false if we're done with the path.
