OMPoly cMode?

Hi all -

I'm interested in creating a diamond shape that represents a sensing area
for an aircraft. I think the best way for me to do this is to use the OMPoly
and specify a lat/lon (center of the sense point) with some x,y pairs for
offsets of the vertices of the diamond. However, the constructor wants an
int cMode (offset coordinate mode) at the end of it and I'm not sure what I
should pass to that. I can't see any indication in the Javadoc as to what
this might be. It's probably obvious and I just can't see it due to "Friday
brain". Can anyone help?

Thanks,
Chris
