Hi,
We have something similar but not exactly the same. You would use this method to capture the page image:
http://www.essentialobjects.com/doc/eo.webbrowser.webview.capture_overloads.aspxThe different is because we use Chromium's engine and Chromium's engine uses GPU to render output. As a result the capturing the code works by directly capture from the GPU frame buffer, which only represents the area that is currently visible in the window. So if you wish to capture the whole page, you must resize the window to fit the whole page without scrolling first --- which can be a problem because the GPU frame buffer may not be able to accommodate that size.
Thanks!
