104 d.northarrow displays a north arrow symbol at the given screen coordi‐
105 nates. If no coordinates are given it will draw the north arrow in the
106 bottom right of the display. It can draw the north arrow in a number of
107 styles (see the wiki page for details). With certain styles of north
108 arrow label ’N’ is displayed by default, and can be changed with option
109 label, for example for different languages. The label can be hidden
110 with -t flag.
111 North arrow can be rotated, for example to align with true north, not
113 grid north. The angle in degrees counter-clockwise (or radians with -r
114 flag) can be specified with option rotation. Label is rotated together
115 with the arrow, unless flag -w is specified.
