ISpeedometerBackground.Image

Syntax

Description

The Image property determines the image that is used as a background.

Example

Executing the example requires a form with the Button1 button and the SpeedometerBox component named SpeedometerBox1. The root of disk C contains the Image.bmp file.

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;

After executing the example, on clicking the button, formatting parameters of the speedometer displayed in the SpeedometerBox1 component are changed. The Image.bmp image is set as a speedometer background.
