The only, but difficult, task is to find the lat/lng coordinates of the **SVG bounding box** - lower left and upper right corner points. Then convert all points' coordinates from (lat,lng) to (x,y) and display them.  Thank you very much for your reply.Do you have any good methods to find the lat/lng coordinates of the SVG bounding box？ -- This is an automated message from the Apache Git Service.
