    <para>
        The box at the bottom of the dialog box displays a sample of the
        current line pattern. You can choose one of the predefined patterns,
        such as Solid or Dashed. Alternatively, you can select Custom,
        and define your own line pattern.

    <para>
        To define a line pattern, type a list of numbers, separated by
        commas, in the box labeled <italic>Segment lengths</italic>. These
        numbers are the lengths, in millimeters, of alternating line segments
        and gaps in the line pattern. If the <italic>First segment is
        visible</italic> box is checked, the first number represents the
        length of a line segment. Otherwise, the first number represents
        the length of a gap.
