[mapserver-users] problem on java mapscript queryByPoint

[Marco Salvatori]

Hello,

I'm using java mapscript
I'm confused with queryByPoint function in  layerObj class.

I want to query a raster layer (Arc/Info Binary Grid) from specific
coordinates to check if
a point is covered by the layer.

The code is the follow:

        pointObj centerPoint = new pointObj(centerX, centerY, 0);
        layerObj layer = map.getLayerByName(layerName);
       
        int resQuery = layer.queryByPoint(map, centerPoint,
mapscript.MS_SINGLE, 180.0);
       .....

calling queryByPoint with mode mapscript.MS_SINGLE is the same as I call the
function with  mapscript.MS_MULTIPLE. My expectation is to have only one
result, but I get many resuts.

I tested the same function using python mapscript and it works correctly.

The question is why this does not work in Java?

Thanks
Marco
