[wxPython] Draw a road map

wxPython Users
1

Hello everybody,

I would like to have some advice.

I'm working on drawing a road map.
I read a data file which contains the central points coordinates (x, y)
of the road, the road width and the number of the lanes. I would like to

draw the road with one or several lane(s).

For the moment, I just use DrawLine with a big width for the pen. But
it's then difficult to draw over fine lines for the lanes, and the end
of the roads are rounded and not straight.

Can I use DrawRectangle to draw "tilted" rectangle
(DrawRectangle(wxCoord x, wxCoord y, wxCoord width, wxCoord height):
just the top left corner and the size are not enought to define a
"tilted" rectangle...)? Do you know other methods to do this?

Thank you very much in advance.
Carole.

Check out wxDC.DrawPolygon, along with some elementary geometry.
