Draw(Graphics: IGxGraphics; Rect: IGxRectF);
Graphics. Graphic context for rendering.
Rect. Real rectangle where a legend is rendered.
The Draw method draws the specified rectangle of territory info.
Executing the example requires a form with the following components: the Button component named Button1, the MapBox component named MapBox1, and the UiMap component named UiMap1. UiMap1 is a data source for MapBox1. The map must be connected to the UiMap1 component.
The example is a handler of the OnClick event for the Button1 component.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
Map: IMap;
TerrI: IMapTerritoryInfo;
Graphics: IGxGraphics;
BitMap: IGxBitmap;
Image: IGxImage;
Rect: IGxRectF;
Begin
Map := UiMap1.Map;
TerrI := New DxMapTerritoryInfo.Create;
Map.View.TerritoryInfo := TerrI;
TerrI.Layer := Map.Layers.FindByName("Regions");
BitMap := TerrI.GetBitmap(150, 150, 92);
Image := BitMap.Clone;
Graphics := GxGraphicsClass.FromImage(Image);
Rect := New GxRectF.Create(0, 0, 20, 20);
TerrI.Draw(Graphics, Rect);
End Sub Button1OnClick;
After executing the example the specified territory info rectangle is drawn.
