Awesomium Webview Surface to Byte Buffer or PictureBox

Question

I begun to develope in C#, and I'm trying to convert a surface to a byte buffer or to a Picture (to convert after to a byte buffer too).

I saw in other question this code:

string fileName = Path.GetTempFileName();
webView2.Render().SaveToPng(fileName);
byte[] bytes = File.ReadAllBytes(fileName);
File.Delete(fileName);
MemoryStream ms = new MemoryStream(bytes);

But, a webview don't have Render(), and he don't say what libraries I need to import.

I stop here:

var view = (WebView)WebCore.Views.Last();
WebCore.Update();
BitmapSurface surface = (BitmapSurface)view.Surface;
surface.??

Answer 1

There have been many undocumented changes in Awesomium lately.

Try WebView.Surface instead of WebView.Render.

using (WebView vw = WebCore.CreateWebView(1024, 768)) {
    vw.Source = new Uri("http://www.google.com");

    while (vw.IsLoading) {
        WebCore.Update();
    }
    ((BitmapSurface)vw.Surface).SaveToJPEG("D:\\google.jpg");
    PictureBox1.Load("D:\\google.jpg");
    WebCore.Shutdown();
}

There have been another set of changes that were pointed out in the comments. Just for the sake of correctness, here is an updated code and a link to the documentation.

using ( webView = WebCore.CreateWebView( 800, 600 ) )
{
    webView.Source = new Uri( "http://www.google.com" );

    view.LoadingFrameComplete += ( s, e ) =>
    {
        if ( !e.IsMainFrame )
            return;

        BitmapSurface surface = (BitmapSurface)view.Surface;
        surface.SaveToPNG( "result.png", true );

        WebCore.Shutdown();
    }
}

WebCore.Run();
