    // This sample shows how to render a web page specified by a URL
    // to a PDF. Here we render the C# source of the WordIndex sample.
    // Similar to HtmlRenderPage0, this sample directly uses GcHtmlRenderer,
    // but shows how to specify options such as page orientation, margins,
    // headers and footers.
    // For reference, the following markup extensions can be used in the
    // header and title templates (all except title are used in this sample):
    // - <span class="date">       - Formatted date
    // - <span class="title">      - Document title
    // - <span class="url">        - Document location
    // - <span class="pageNumber"> - Current page number
    // - <span class="totalPages"> - Total number of pages
    // Please see notes in comments at the top of HelloWorldHtml
    // sample code for details on adding GcHtml to your projects.

                // - IgnoreCSSPageSize makes sure page size specified here is used.
                // - Landscape allows to change page orientation.
                // - Scale allows to enlarge or reduce the render size (default is 1).
