Pro SDK GeometryBag Extent not implemented

MartinVDW

Hi, Looking at the GeometryBag in the SDK the extent property is not implemented. Is there another way of getting the extent of the added geometries in the GeometryBag. The samples show how to add geometries using the GeometryBagBuilder, get the GeometryBag and check the geometries added. But not all the functionality as in ArcObjects. Am I missing something?

SDK: ArcGIS Pro 2.4 API Reference Guide 

Samples: ProSnippets Geometry · Esri/arcgis-pro-sdk Wiki · GitHub  

Thank you.

This works for me with 2.9 (see Extent at end)

private static void Test()
{
    //from here: https://pro.arcgis.com/en/pro-app/latest/sdk/api-reference/#topic20909.html
    using (GeometryBagBuilder builder = new GeometryBagBuilder(SpatialReferences.WGS84))
    {
        GeometryBag emptyBag = builder.ToGeometry();
        // emptyBag.IsEmpty = true

        MapPoint point = MapPointBuilder.CreateMapPoint(1, 2, SpatialReferences.WebMercator);
        builder.AddGeometry(point);
        // builder.CountGeometries = 1

        GeometryBag geometryBag = builder.ToGeometry();
        // geometryBag.PartCount = 1
        // geometryBag.PointCount = 1
        // geometryBag.IsEmpty = false

        IReadOnlyList<Geometry> geometries = geometryBag.Geometries;
        // geometries.Count = 1
        // geometries[0] is MapPoint with a sr of WGS84

        bool isEqual = geometryBag.IsEqual(emptyBag);   // isEqual = false

        List<Coordinate2D> coords2D = new List<Coordinate2D>()
        {
            new Coordinate2D(0, 0),
            new Coordinate2D(0, 1),
            new Coordinate2D(1, 1),
            new Coordinate2D(1, 0)
        };

        Multipoint multipoint = MultipointBuilder.CreateMultipoint(coords2D, SpatialReferences.WGS84);
        builder.InsertGeometry(0, multipoint);
        geometryBag = builder.ToGeometry();
        // geometryBag.PartCount = 2

        geometries = geometryBag.Geometries;
        // geometries.Count = 2
        // geometries[0] is Multipoint
        // geometries[1] is MapPoint

        Polyline polyline = PolylineBuilder.CreatePolyline(coords2D, SpatialReferences.WebMercator);
        builder.AddGeometry(polyline);
        //builder.RemoveGeometry(1);
        geometryBag = builder.ToGeometry();
        // geometryBag.PartCount = 2

        geometries = geometryBag.Geometries;
        // geometries.Count = 2
        // geometries[0] is Multipoint
        // geometries[1] is Polyline
        var ext = geometryBag.Extent;
        Console.WriteLine(ext.ToJson());
    }
}
