#### 8.6.2 Shadow Attributes

`shadow.offset`

  If not set to zero, then the element will have a shadow (default is 0). The value of this attribute then determines, how much the shadow is offset (in pixels), in other words how "deep" the shadow is below the entity or box. In graphviz, this attribute is called `shadow_offset`.

`shadow.color`

  The color of the shadow. This attribute is ignored if shadow.offset is 0. In graphviz, this attribute is called `shadow_color`.

`shadow.blur`

  Specifies how much the shadow edge is blurred (in pixels). E.g., if shadow.offset is 10 and shadow.blur is 5, then half of the visible shadow will be blurred. Blurring is implemented by gradually changing the shadow color’s transparency towards fully transparent. This attribute is ignored if `shadow.offset` is 0. In graphviz, this attribute is called `shadow_blur`.
