[mapserver-users] Re: How to add attributes to feature/shape with mapscript java?

[rai 8]

Hi!,

Finaly I found the way set the id of a feature, mapscript maps the last
value set by setvalue with layer.setClassItem ,but I only can add a one
attribute with layer.setFilteritem("itemName");

// Features add
for (Iterator iterator = sites.iterator(); iterator.hasNext();) {

          Site site = (Site) iterator.next();
    shapeObj shape = new shapeObj( mapscriptConstants.MS_SHP_POINTM );
    lineObj line = new lineObj();

    // latlon source data
    pointObj point = new pointObj( site.getLatLonPosition().getX() ,
site.getLatLonPosition().getY() , 0);

    shape = point.toShape();

    shape.initValues(2);
    shape.setValue(0, site.getId().toString() ); // ID
    layer.addFeature(shape );
 }
}

layer.setClassitem("id");

I think that the way to add many attributes is with layer.SetItems but isn't
implemented in mapscript swig, I found in maplayer.c msLayerSetItems function,
why setlayerItem is not appear in mapscript?

/*
** A helper function to set the items to be retrieved with a particular
shape. Unused at the moment but will be used
** from within MapScript. Should not need modification.
*/
int msLayerSetItems(layerObj *layer, char **items, int numitems)


Another problem that I have is to reproject the data, It seems that there is
a bug with reprojections in mapscript, if projection map and projection
layer is not the same the reprojected coordinates aren't correct. Also if I
try to reproject manualy the coordinates are wrong. I'm leaving something?

projectionObj proj4326 = new projectionObj("EPSG:4326");
    projectionObj proj32631 = new projectionObj("EPSG:32631");
    point.project(proj4326, proj32631);


thanks!
