Specifying stroke and fill properties
You can use the Stroke tab on the Inspector to specify the stroke properties and fill properties for vector shape objects and text objects. The stroke is the outline of an object; the fill is the inside of an object.
You can choose to specify a color for the stroke, or you can choose a stroke value of None to not display an outline for an object. If you specify a color, you can also specify the stroke width and several other stroke attributes.
You can choose to fill an object with either a color or a pattern, you can choose to not fill the object at all.
You can animate the stroke color, stroke width, and fill color properties.
