How can i convert html document to image using CefSharp?

There is no direct support for doing this. You may be able to look at the WPF WebView code in CefSharp, which renders a webpage to an offscreen buffer and then draws to the screen.

In CEF there is a CefBrowser.GetImage() [1] method with which you can take a screenshot

of a webpage:

virtual bool GetImage(PaintElementType type, int width, int height,

void* buffer) =0;

I've implemented feature of taking full web page snapshot in a forked branch https://github.com/ivan-sam/CefSharp. This implementation depends on a another commit that fixes script evaluation bug https://github.com/cefsharp/CefSharp/issues/445 , so please clone or download the whole branch.

I've modified CefSharp.Wpf.Example project and added Snapshot button that makes snapshot of the page and opens an image.

If you need to use this feature in WinForms app you can host WPF control with ElementHost
