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;
    Bitmap: IGxBitmap;
Begin
    Map := UiMap1.Map;
    Bitmap := Map.GetBitmap(300, 150, 96);
    Bitmap.SaveToFile("C:\Map.gif");
End Sub Button1OnClick;

After executing the example the map graphic presentation is saved to file with the following properties: width - 300 pixels, height - 150 pixels, resolution - 96 dpi.
