[Gdal-dev] Problem with geometry

[vuilleumier vincent]

Hi,
I'm making a little GIS application in python using wxPython for the layout. To do this, I need to read the (x, y) of each feature on a layer. With a point's feature I use the GetX and GetY's methods, but I don't know how to do with a polygon's feature or line's feature. For this two features, I need to read the x, y of all the points to draw them back on a canvas. Knows someone the methods to use ?

thanks
Vincent
