Quickly create thumbnails of websites

Use the WebBrowser Control in .Net to quickly create Thumbnails of WebSites.

WebBrowser control in .Net can be used to take thumbnail/ Screenshots of websites. 
Then use the Bitmap Class to save them locally.

Code snippet shown below:

public Bitmap GenerateThumbnail(string url)
{
    //rendered at full size
    return GenerateScreenshot(url, -1, -1);
}
 
public Bitmap GenerateThumbnail(string url, int width, int height)
{
    // Load the webpage into a WebBrowser control
    WebBrowser wb = new WebBrowser();
    wb.ScrollBarsEnabled = false;
    wb.ScriptErrorsSuppressed = true;
    wb.Navigate(url);
    while (wb.ReadyState != WebBrowserReadyState.Complete) {   Application.DoEvents(); }

    // Set the size of the WebBrowser control
    wb.Width = width;
    wb.Height = height;

    if (width == -1)
    {
        // Take Screenshot of the web pages full width
        wb.Width = wb.Document.Body.ScrollRectangle.Width;
    }
 
    if (height == -1)
    {
        // Take Screenshot of the web pages full height
        wb.Height = wb.Document.Body.ScrollRectangle.Height;

    }

 
    // Get a Bitmap representation of the webpage as it's rendered in the WebBrowser control
    Bitmap bitmap = new Bitmap(wb.Width, wb.Height);
    wb.DrawToBitmap(bitmap, new Rectangle(0, 0, wb.Width, wb.Height));
    wb.Dispose();

    return bitmap;

} 
 

Notes:
// Generate thumbnail of www.devx.com at 1024x768 resolution
Bitmap thumbnail = GenerateThumbnail("http://www.eggheadcafe.com", 1024, 768); 

// Generate thumbnail of a www.devx.com at full size
thumbnail = GenerateThumbnail("http://www.eggheadcafe.com");
