export class ViewerLoadFromLocalExample { 
    private _viewer: lt.LEADVIEW.Viewer = null; 
    private _file: File = null; 
 
    public constructor() { 
        if(lt.RasterSupport.kernelExpired)

    } 
 
    public run = (divID: string, buttonID: string): void => { 
        const lv = new lt.LEADVIEW.Viewer(); 
 
        // Builds a new instance of LEADVIEW. 
        // For the full list of options that can be passed to the run method, 
        // refer to the settings JSON files that are included in the LEADVIEW demo application. 
        // Settings files can also be generated from the LEADVIEW application itself. 
        lv.run(null, { 
            'rootDivId': divID, 
            'showMainMenu': false, 
            'serviceHost': 'http://localhost:40000', // or wherever your host is 
            'servicePath': '', // the path to the root of the service, which is nothing for this example 
            'serviceApiPath': 'api', // Routing occurs at "/api", unless you change the routing in the DocumentsService 
        });

    }
