New Post: New draw

or I can set the radius of which will not be change when zooming?

double x = 0;
double y = 0;
MapWinGIS.Point pnt = new MapWinGIS.Point();
map.PixelToProj(e.x, e.y, ref x, ref y);
pnt.x = x;
pnt.y = y;
int draw_hndl = map.NewDrawing(MapWinGIS.tkDrawReferenceList.dlSpatiallyReferencedList);
map.DrawCircle(pnt.x, pnt.y, 1, 20, false);
