[mapserver-users] Clipping

[Joshua Hevenor]

Good morning list, 
I'm looking for a function and/or method to clip a 
polygon. In general, I need to limit a polygon to the map boundary for export 
(export as shapefile from a web map)...so if I had a 20x20 square that was 
overlapping the visible map by 10 units, the exported result would be a 10x20 
rectangle.  PHP MapScript is my weapon of choice.  I'd also welcome opinions on 
the approach or suggestions for alternatives.


Thanks for your assistance,


Josh
