26 | |
27 | ---Version: |
28 | |
29 | ---Purpose: The primitive EllipsMarker |
30 | -- Every marker takes a reference point as an argument in |
31 | -- its constructor. CircleMarker and EllipsMarker take |
32 | -- another point as the center and PolylineMarker takes the |
33 | -- first point of its list as its origin. |
34 | -- The coordinates of the centre or origin point are offsets |
35 | -- with respect to the reference point. |
