Example

Executing the example requires a form with the Button1 button and the ImageBox component named ImageBox1. The repository should contain a regular report with the REPORT identifier.

Add links to the Drawing and Metabase system assemblies.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Mb: IMetabase;
    Doc: IGxDocument;
    Img: IGxImage;
Begin
    Mb := MetabaseClass.Active;
    Doc := Mb.ItemById("REPORT").Bind As IGxDocument;
    Img := Doc.Preview(GxImageFormats.Png);
    ImageBox1.Image := Img;
End Sub Button1OnClick;

Clicking the button loads an image for report preview to the ImageBox1 component.
