Is there any possible way to replace the shape of Guardzone from circle to atleast a rectangle by just modifying the function, bool ocpn_draw_pi::CreateGZLeftClick( wxMouseEvent &event )?
The only thing matter is the shape of the boundary right? the other functionalities are same.
ie Draw the boundary using Mouse events
with respect to the center of the boat.
As an initial step I would like to implement at least a rectangle boundary moving with the boat.
If you have any idea regarding this, please let me know.
