Print content of a WebView

Question

I have a web view that displays a fancy bar graph. I need to basically take a screenshot of it (entire HTML document, not just area currently visible in the webview control) and stuff it into a PDF. The HTML file is generated by my app, so I can add anything I want to it. Working with PDF is also not an issue.

The question is how do I go about grabbing rendered HTML document as a bitmap? Ideas on a high level approach would be helpful.

Note that HTML graph is done with DHTML and not canvas, so solution described here does not apply

If the second answer to that question -- using `capturePicture()` -- does not apply, then you are out of luck for doing anything on the device, AFAIK. — CommonsWare, Jan 04 '13 at 20:05

If you can use stream for generate pdf starting for generated image the path is that:

Picture picture = webView.capturePicture();
Bitmap  b = Bitmap.createBitmap(picture.getWidth(), picture.getHeight(), 
                                Bitmap.Config.ARGB_8888);

Canvas c = new Canvas( b );        
picture.draw( c );

FileOutputStream out = null;
byte[] byteArchadeImage = null;

try {
    out = new FileOutputStream(new File("/sdcard/snapshot/view-cutted.jpg"));

    if ( out != null ) {
        b.compress(Bitmap.CompressFormat.JPEG, 100, out);
        out.flush();
        out.close();
    }
} catch( Exception e ) {
    Log.e("MSG", e.getLocalizedMessage());    
}

You can redirect stream for pdf generation with any tool for pdf generate that functioning on android. I believe that iText is one sample for that.
