new IWGeometryFilter()

Methods

clear(map)

resets the geometryFilter (removes renderers and shapes)
Parameters:
Name Type Description

drawGetLayerResult(result, renderingAttributes, highlightingAttributes, map, callback, options)

draw the geometries of the given result object on the map.
Parameters:
Name Type Description
result object the result of getLayer function (contains array of geometries, extent and layer infos)
renderingAttributes object a set of CSS attributes to render the filtered polygons, e.g. {fill: "red", fillOpacity: 0, stroke: "grey", strokeWidth: 5}

area object an area to bound the shapes, e.g. {topleft: "697526,6759257", bottomright: "789250,6667533"}, a bounding box {coord: "726113,6702540", radius: 16758}, a circle {polygon: ["727641,6713853","739566,6726694","749197,6708808"]}, a polygon
filters array a list of filter objects, e.g. {type: "prefix", key: "PLZ", value: "5"} a prefix filter to select only postal codes starting with 5
renderingAttributes object a set of CSS attributes to render the filtered polygons, e.g. {fill: "red", fillOpacity: 0, stroke: "grey", strokeWidth: 5}

map IWMap a map
callback function the callback function
options object set tooltip attribute or textAttributes E.g {tooltip:{value:'$ID$ $NAME$'}, textAttributes:{value:'NAME', renderOptions: {fill: 'red',fontSize: '30px', fontWeight: 'bold'}, boxAttributes: {fill: 'white'}}}

getLayer(layerId, area, filters, zoom, callback)

Requests geometry and attributes from the given layer.
Parameters:
Name Type Description
layerId String ID of the layer, e.g. KGS
area object an area to bound the shapes, e.g. {topleft: "697526,6759257", bottomright: "789250,6667533"}, a bounding box {coord: "726113,6702540", radius: 16758}, a circle {polygon: ["727641,6713853","739566,6726694","749197,6708808"]}, a polygon
filters array a list of filter objects, e.g. {type: "prefix", key: "PLZ", value: "5"} a prefix filter to select only postal codes starting with 5
zoom number preffered zoom level (depends on the zoom range of the layer, if it is out of range no layer is returned). Default is 13
callback function the callback function
