I was wondering if is possible to use GDK to develop a app capable of creating vignettes on Glass, like this.
Is it possible?

If you see the tags there is a specific tag [google-gdk](http://stackoverflow.com/questions/tagged/google-gdk) for that purpose. – llrs Apr 04 '14 at 12:48

What "vignette" do you want to create (location? time? other?). You might send the image to your server and add the vignette as a response (like the "cats" improve picture demo). – ErstwhileIII Apr 06 '14 at 14:01

I imagine the vignette being independent from the running program. If I am using Google Maps, the vignette should be created with the displayed map. If I am using Facebook, the vignette should show the facebook screen... and so on. – Emerson Takahashi Apr 07 '14 at 13:48

Interesting question. I imagine your app would need to do 3 steps:
- Take a screenshot
- Take a picture
- Put them together
Steps 2 and 3 are pretty easy and shouldn't be a problem on Glass.
When it comes to step 1, you can take a screenshot from your app in Android by creating a bitmap from a view, which should work on Glass as well. But I don't think you can screenshot other apps or the timeline, so I don't think it is doable in general.
