Width: IMapVisualNumericProperty;
The property is read-only.
The Width property returns icon factor width parameters.
Executing the example requires a form, a button named Button1 on the form, the UiMap component named UiMap1 that is a data source for the MapBox component. The map must be connected to the UiMap1 component. The VisualDataAdapter class, that creates a dynamic data source, must also be implemented. The class example is contained in the IMapVisual.DataAdapter property description. The "C:\blue.gif" file, that contains the image, must be present in the file system.
Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
Map: IMap;
Layer: IMapLayer;
ImageVisual: IMapImageVisual;
Image: IGxImage;
Begin
Map := UiMap1.Map;
Layer := Map.Layers.FindByName("Regions");
ImageVisual := Layer.Visuals.AddImageVisual;
ImageVisual.DataAdapter := New VisualDataAdapter.Create As IMapDynamicDataAdapter;
Image := GxImage.FromFile("C:\blue.gif");
ImageVisual.Image.Value := Image;
ImageVisual.Height.Value := 4;
ImageVisual.Width.Value := 4;
End Sub Button1OnClick;
After executing the example the icon factor, that has the length and the width of 4 pixels, is added to the Regions layer.
