WPViewPDF.GetMetafile doesn't work (v1.1.8.0)

    The example below doesn't work either.
    https://www.wpcubed.com/ftp/ex/WPViewPDF_BMP.zip

    Here is the some code I find in the code of the component.

    // This function is not available in the demo version!
    function TWPViewPDF.PrintHDC(PageNO: Integer; DC: HDC; ResX, ResY: Integer): Boolean;
    begin
    // if GetDeviceCaps(DC, LOGPIXELSX)<> ResX then
    CommandEx(COMPDF_PrintHDCSetXRes, ResX);
    // if GetDeviceCaps(DC, LOGPIXELSY)<ResY>= 0;
    end;

    function TWPViewPDF.GetMetafile(PageNO: Integer): TMetafile;
    var acanvas: TMetafileCanvas;
    w, h: Integer;
    begin
    if (PageNO <0> PageCount) then
    raise Exception.Create('Page not available')
    else
    begin
    Result := TMetafile.Create();
    w := Command(COMPDF_GetPageWidth);
    h := Command(COMPDF_GetPageHeight);
    Result.MMWidth := Round(w / 72 * 2540);
    Result.MMHeight := Round(h / 72 * 2540);
    Result.Width := Round(w / 96);
    Result.Height := Round(h / 96);
    acanvas := TMetafileCanvas.CreateWithComment(Result, 0,
    'Created by WPViewPDF - http://www.wptools.de',
    'PDF Metafile - Page ' + IntToStr(PageNo));
    try
    PrintHDC(PageNO, acanvas.Handle, 96, 96);
    finally
    acanvas.Free;
    end;
    end;
    end;

    Does it mean I need to get the updated version or new license? If yes, could you please tell me which version or licence can make it work? Thanks a lot.
