[fusion-users] Re: Show Layer added in MapScript

[Paul Deschamps]

Here's a couple func's i've used in the past:

 function addPoint($oMap,$szName,$x,$y,$szSymbolName,$aColor1,$aColor2){
        // create layer
        $layer = ms_newLayerObj($oMap);
        $layer->set("name",$szName);
        $layer->set("status",MS_DEFAULT);
        $layer->set("type",MS_LAYER_POINT);

        // create class
        $class = ms_newClassObj($layer);
        $class->set("name",$szName);
        // set style
        $style = ms_newStyleObj($class);
        $style->set('symbolname',$szSymbolName);
        $style->set('size',12);
        $style->set('angle',0);
        $style->set('width',4);
        $style->color->setRGB($aColor1[0],$aColor1[1],$aColor1[2]);
        $style->outlinecolor->setRGB($aColor2[0],$aColor2[1],$aColor2[2]);

        // add lines / points to shape
        if ($x != "" && $y != ""){
            $shape = ms_newShapeObj(MS_SHAPE_POINT);
            $oLine = ms_newLineObj();
            $oLine->addXY($x,$y);
            $shape->add($oLine);
            $layer->addFeature($shape);
        }
    return $oMap;
    }

    function addPolygonFeatureToMap($oMap, $polygon_coordinates, $label,$oRGB){

        // create layer
        $layer = ms_newLayerObj($oMap);
        $layer->set("name","POLY_".$label);
        $layer->set("status",MS_DEFAULT);
        $layer->set("type",MS_LAYER_POLYGON);

        // create class
        $class = ms_newClassObj($layer);
        $class->set("name",$label);
        // set style
        $style = ms_newStyleObj($class);
        $outlineColor = $oRGB->outline;
        $fillColor = $oRGB->color;
        $style->color->setRGB($fillColor->r,$fillColor->g,$fillColor->b);
        $style->outlinecolor->setRGB($outlineColor->r,$outlineColor->g,$outlineColor->b);

        // add points
        $line = ms_newLineObj();
        foreach ($polygon_coordinates as $record){
            $point = ms_newPointObj();
            $x = $record->x;
            $y = $record->y;
            $point->setXY($x,$y);
            $line->add($point);
            }

        // add the first point again to close the polygon
        if(count($polygon_coordinates) > 2){
            $point = ms_newPointObj();
            $x = $polygon_coordinates[0]->x;
            $y = $polygon_coordinates[0]->y;
            $point->setXY($x,$y);
            $line->add($point);
            }

        // add lines / points to shape
        $shape = ms_newShapeObj(MS_SHAPE_POLYGON);
        $shape->set("classindex", 0);
        $shape->add($line);
        $layer->addFeature($shape);
        return $oMap;
    }

Hope this helps

Cheers
