Layer from MS_LAYER_RASTER type did'nt have getExtent()

[mapmaniac]

i have written a java mapscript like this to get the Extent of the layer defined in the mapfile:

        System.loadLibrary("mapscript");

        mapObj map = new mapObj("C:/AppsJava/mapserver_java/test.map");
        int size = map.getNumlayers();
        for (int i=0;i<size;i++){
            layerObj layer=map.getLayer(i);
            layer.setTemplate("template.html");
            pointObj p = new pointObj(4.868779043979817,44.99013635404045,0);
            layer.queryByPoint(map, p3a, mapscriptConstants.MS_SINGLE, 1)

            try {
            System.out.println(layer.getExtent().getMinx());
            System.out.println(layer.getExtent().getMiny());
            System.out.println(layer.getExtent().getMaxx());
            System.out.println(layer.getExtent().getMaxy());
            } catch (ParseException e) {
                e.printStackTrace();
            }
        }

If the type of the layer is MS_LAYER_RASTER, i get wrong values for the Extent.

I looked to the sources and i found in maprasterquery.c

int msRASTERLayerGetExtent(layerObj *layer, rectObj *extent)
	{ return MS_FAILURE; }

So i think that this is'nt implemented. Is this right? Can you fix this?

Thank you very much
