Hi John,
I used the following code to test WrapDataLine mode with SingleTile, it works.
wpfMap1.MapUnit = GeographyUnit.DecimalDegree;
WorldMapKitWmsWpfOverlay worldMapKitOverlay = new WorldMapKitWmsWpfOverlay();
wpfMap1.Overlays.Add(worldMapKitOverlay);
worldMapKitOverlay.WrappingMode = WrappingMode.WrapDateline;
ShapeFileFeatureLayer worldLayer = new ShapeFileFeatureLayer(@"..\..\SampleData\Data\Countries02.shp");
worldLayer.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level20;
worldLayer.ZoomLevelSet.ZoomLevel01.DefaultAreaStyle = AreaStyles.CreateSimpleAreaStyle(GeoColor.SimpleColors.Transparent, GeoColor.FromArgb(100, GeoColor.SimpleColors.Green));
worldLayer.WrappingMode = WrappingMode.WrapDateline;
worldLayer.WrappingExtent = new RectangleShape(-180,90,180,0);
LayerOverlay staticOverlay = new LayerOverlay();
staticOverlay.Layers.Add("WorldLayer", worldLayer);
staticOverlay.TileType = TileType.SingleTile;
wpfMap1.Overlays.Add(staticOverlay);
wpfMap1.CurrentExtent = new RectangleShape(-133.2515625, 89.2484375, 126.9046875, -88.290625);
wpfMap1.Refresh();
Please let me know if you have further questions.
Regards,
Ivan
