[mapguide-users] RE: RE: Buffer rectangle

[Jim O'Leary]

I am already calling the Buffer() method from an MgGeometry polygon with an
arbitrary number of x,y coordinates. However, the buffer that the method
returns is a circle, and not the shape of that polygon. 

I took my code from the Autodesk Dev Guide sample
selectfeaturesinbuffer.php, and also from buffer.php in the mapviewerphp
folder. Both of those programs also return a round buffer from an MgGeometry
polygon. Does this mean it is not possible to produce a rectangle polygon?

Thanks
