    • draw

      public abstract void draw​(Canvas canvas)
      Draw the graphic on the supplied canvas. Drawing should use the following methods to convert to view coordinates for the graphics that are drawn:
      1. scaleX(float) and scaleY(float) adjust the size of the supplied value from the preview scale to the view scale.
      2. translateX(float) and translateY(float) adjust the coordinate from the preview's coordinate system to the view coordinate system.
      Parameters:
      canvas - drawing canvas
