Jose,

As far as I know you will need to build your own routine for this.
Have a look at this thread to get you started:

http://groups.google.com/group/comp.lang.idl-pvwave/browse_f rm/thread/4b90c8f4a2c7b715/782d5e7153c7fda8?lnk=gst&q=Ap ply+shapefile#782d5e7153c7fda8

This thread mostly deals with building masks from EVF files (that were
created by converting shapefiles) but you could modify the process to
work with an IDLffShape object.

Good luck,
Jeff
