    `sy` - The start y coordiante of the path

Method Detail

### startHole

    public void startHole(float sx,
                          float sy)

  Start building a hole in the previously defined contour

  Parameters:
    `sx` - The start point of the hole
    `sy` - The start point of the hole

### lineTo

    public void lineTo(float x,
                       float y)

  Add a line to the contour or hole which ends at the specified location.

  Parameters:

    `y` - The y coordiante to draw the line to

### close

    public void close()

  Close the path to form a polygon

### curveTo

    public void curveTo(float x,
                        float y,
