Save to Bitmap Example

[drich...@secondstory.com]

Would it be possible to create an example that just saves a screenshot to a bitmap? Without using Windows Forms or WPF?  I've tried extricating the necessary code from the WPFOSR example but I haven't been able to get it to work.  The OnPaint method is never called despite the having overridden GetRenderHandler on the client and having created a render handler with the OnPaint method defined.

Can you provide your's sample?

Hmm. I've been writing my test to work with OpenTK, an OpenGL library for C#. But you have a good idea.  I will extract the relevant CefGlue code and write an example for saving to a bitmap and then you can review it.  I'll post it once I'm done with it, probably in an hour or so.

Good idea. Thanks.

Implement method in CefSimpleRenderHandler like this:

        protected override bool GetViewRect(CefBrowser browser, ref CefRectangle rect)

        {

            rect = new CefRectangle(0, 0, 300, 200);

            return true;

        }

In this case - OnPaint called. I'm not sure that is happens if view rectange is not provided, but probably it is means drawing on canvas 0x0 (and it is not happens).

I've partially completed Save to Bitmap example.  OnPaint in the render handler never gets called.  Could you take a look and tell me why? Once I figure that out I'll be able to complete the example.

I'll share it with the group.
