I have a loop that goes through all the items in a tab file that looks about like this:
pFeat = table->GetNextFeature(); if(//check to see if it's a polygon etc... then if it is I get it's geometry and cast it to a polygon OGRGeometry *poGeom = pFeat->GetGeometryRef(); OGRPolygon *poPolygon = (OGRPolygon*)poGeom; OGRPoint *pPt = new OGRPoint; poPolygon->Centroid(pPt); Now if I call: pPt->getX() or pPt->getY() They always return 0.0 yet if I extract the rings I can calculate the Center of gravity just fine. Does anyone know what I might be doing wrong? Thank you, Andy ------------------------ Yahoo!
