Represents line and arrowhead formatting.
For a line, the LineFormat object contains formatting information for the line itself; for a shape with a border, this object contains formatting information for the shape's border.
The following example adds a blue, dashed line to myDocument. There's a short, narrow oval at the line's starting point and a long, wide triangle at its end point.
