Donald, I haven't tried this, but di you try using Image (pixel) values for the buffer?
bobb >>> "Donald Kerr" <[email protected]> 01/08/09 11:47 AM >>> I'd appreciate it if someone could give me some clarification please? I am using the following url to return an image: http://localhost/cgi-bin/mapserv.exe?map=/ms4w/os.map&mode=map&mapsize=500+4 00&mapxy=258544+665909&layers=all&buffer=2000 The documentation states, "BUFFER [distance] - A distance, in the same coordinate system as the map file, used in conjunction with MAPXY to create an new map extent". The coordinate system is in metres so I would expect that the width of the image (500px) would be 2000m (2km). That doesn't seem to be the case i.e. the returned images is, at a guess, double that. I need clarification on what "buffer" is actually doing. No doubt I'm way off the mark with the deduction above! Many thanks.
