For right-to-left languages such as Arabic or Hebrew, the viewer interface can be mirrored. This example enables RTL mode.

Viewer setup. Configure the viewer, load the report, assign it to the component, and process the requests or events raised by the UI.
@Component({
    selector: "rtl-viewer",
    imports: [Viewer],
    template: `<sti-viewer [report]="report" [options]="viewerOptions"></sti-viewer>`
})
export class RtlViewer {
    report = new Stimulsoft.Report.StiReport();
    viewerOptions = new Stimulsoft.Viewer.StiViewerOptions();
    constructor() {
        this.report.loadFile("Reports/BookmarksAndHyperlinks.mrt");
        this.viewerOptions.appearance.rightToLeft = true;
    }
}

Setting appearance.rightToLeft = true lays the toolbar, panels and scrollbars out right-to-left for a fully localized experience.
