All shapes support the following additional properties

  • borderColor: defines the color of the shape's outline. If false, the outline will not be drawn.
  • borderWidth: defines the thickness of the shape's outline.
  • fill: defines the color, paint or gradient to fill the shape's content.
  • opacity: controls how much of the shape is visible, value must be in the range [0..1], default is 1.
  • asShape: creates the shape but does not render to the screen, useful for mixing complex shapes.
  • asImage: creates the shape but does not render to the screen, useful for drawing images or applying textures.
