// 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 directly use the GcHtmlRenderer class
// to render the page to a temporary PDF file, which is then
// returned in the output stream.
// A more flexible way that allows to easily add HTML conetnt
// to a PDF file along with other content is via the extension
// methods GcPdfGraphics.MeasureHtml()/GcPdfGraphics.DrawHtml()
// as demonstrated by HelloWorldHtml and other samples.
//
// Please see notes in comments at the top of HelloWorldHtml
// sample code for details on adding GcHtml to your projects.

{
// Get a temporary file where the web page will be rendered:
var tmp = Path.GetTempFileName();
// The Uri of the web page to render:
var uri = new Uri("http://www.google.com");
// Create a GcHtmlRenderer with the source Uri
// (note that GcHtmlRenderer ctor and other HTML rendering methods accept either a Uri
// specifying the HTML page to render, or a string which represents the actual HTML):
using (var re = new GcHtmlRenderer(uri))
// Render the source Web page to the temporary file:
re.RenderToPdf(tmp);
// Copy the created PDF from the temp file to target stream:
using (var ts = File.OpenRead(tmp))
ts.CopyTo(stream);
// Clean up:
File.Delete(tmp);
// Done.
