I see, .... USER ERROR :-)
Thanks a bunch

Why are you using getBoundary()? It looks like this is converting the
polygon to a linestring - which explains your result.

Hello everyone
I am new to OpenJump. While trying to get familiar with the code and
concepts
I encountered the following:
I have a coordinate object that I want to test against a polygon but
the obvious
does not come out to be true the point in clearly within the polygon
but it comes out as disjoint.
Any Ideas? Am I doing this wrong? is this a bug?
========================================================== the code
private boolean isOutside(Coordinate coordinate) {
GeometryFactory factory = new GeometryFactory();
Geometry pt= factory.createPoint(coordinate);
Collection selectedFeatures =
getPanel().getSelectionManager().getFeaturesWithSelectedItems();
Iterator it=selectedFeatures.iterator();
boolean isOut=false;
for(;it.hasNext() ;){
Geometry candidate = ((Polygon)
((Feature)it.next()).getGeometry()).getBoundary();
isOut= isOut? isOut : candidate.disjoint(pt);
System.out.println("the point \n\t"+pt+"\n and the
poly\n\t");
for (int
vrt=0;vrt<candidate.getCoordinates().length;vrt++)
System.out.println(candidate.getCoordinates()[vrt]);
System.out.println(" within "+candidate.within(pt));
System.out.println(" contains "+candidate.contains(pt));
System.out.println(" disjoint "+candidate.disjoint(pt));
System.out.println(" intersects
"+candidate.intersects(pt));
System.out.println(" coveredBy

System.out.println(" covers "+candidate.covers(pt));
System.out.println(" crosses "+candidate.crosses(pt));
System.out.println(" distance "+candidate.distance(pt));
System.out.println(" relate "+candidate.relate(pt));
}
return isOut;
