    // This sample shows the simplest way to render a web page
    // specified by a URL to a PDF (here we render the Google home page).
    //
    // In this sample we use GcHtmlBrowser to create an instance of HtmlPage
    // that loads the specified URI, and then call the HtmlPage.SaveAsPdf()
    // method to render the page to PDF.
    //
    // A different approach that allows you to easily add HTML content
    // to a PDF file along with other content is via the extension
    // methods GcPdfGraphics.MeasureHtml()/GcPdfGraphics.DrawHtml()
    // as demonstrated by HelloWorldHtml and other samples.
    // Note that those methods require an instance of GcHtmlBrowser
    // to be passed as parameter.
    //
    // Please see notes in comments at the top of HelloWorldHtml
    // sample code for details on adding DsHtml to your projects.
