flash export: questions about the GetIntersection

Hi all, Christian,
I am still puzzled about the GetIntersection() in 
Writer::Impl_writePolyPolygon()
     rPolyPoly.GetIntersection( *mpClipPolyPolygon,
aPolyPoly );
What is mpClipPolyPolygon presented for£¿What's the result
after this code? What's the relationship between rPolyPoly
and aPolyPoly ?

Best Regards,
Fang

Hi Fang,

mpClipPolyPolygon is the current clipping geometry. It is
used for clipping.
The result of

rPolyPoly.GetIntersection( *mpClipPolyPolygon, aPolyPoly );

is a geometry that only contains the parts of aPolyPoly that
are inside
of mpClipPolyPolygon.

rPolyPoly is the unclipped geometry and aPolyPoly is the
clipped geometry.

Regards,
Christian.
