ImageDrawStyle: SpeedometerImageDrawStyle;
The ImageDrawStyle property determines the method of image drawing in the background area.
Executing this example requires a form with the Button1 button and the SpeedometerBox component named SpeedometerBox1. There is Image.bmp file in the root of disk C.
Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
s: ISpeedometer;
v: ISpeedometerView;
Back: ISpeedometerBackground;
Begin
s := SpeedometerBox1.Speedometer;
v := s.View;
s.BeginUpdate;
Back := v.Background;
Back.Type := SpeedometerBackgroundType.Picture;
Back.Image := GxImage.FromFile("C:\Image.bmp");
Back.ImageDrawStyle := SpeedometerImageDrawStyle.Stretch;
s.EndUpdate;
End Sub Button1OnClick;
If the user presses the button after executing this example, the parameters of speedometer design that is displayed in the SpeedometerBox1 component are changed. The Image.bmp image is set as speedometer background. The image is stretched to the entire area of the component.
