[mapserver-users] shape->intesects

[Jean-François MONY]

Hi,

I'm using mapscript with php as a DSO from the mapserver 3.4 on linux.

I've some questions on the intersects fonction of a shape object.
I've tried it on multi-part polygon and the result was not really fine.
After some search, I find that the total inclusion of a polygon in another was 
not take in count by this function.

After a look on the mapscript.i, I thought that the problem came from :
 
   int intersects(shapeObj *shape) {
     switch(self->type) {
     case(MS_SHAPE_LINE):
       switch(shape->type) {
       case(MS_SHAPE_LINE):
         return msIntersectPolylines(self, shape);
       case(MS_SHAPE_POLYGON):
         return msIntersectPolylinePolygon(self, shape);
       }
       break;
     case(MS_SHAPE_POLYGON):
       switch(shape->type) {
       case(MS_SHAPE_LINE):
         return msIntersectPolylinePolygon(shape, self);
       case(MS_SHAPE_POLYGON):
         return msIntersectPolylines(self, shape); <<=======
       }
       break;
     }
 
     return -1;
   }
 
But I've tried to recompil mapserver with the following modification, and 
nothing change.

         return msIntersectPolygons(self, shape);  <<=======


Is there somebody with a comment or an idea ?

Thanks everybody
