title: How can I get the graphical output from another program?
body: <p>I'm trying to build my own remote desktop which can be accessed by the browser. My first idea was building a server (with python I would use flask) and including the graphical output of the OS into my html page. Because I thought that that would be difficult/not possible my next plan is to get just the graphical output of one program which I started from the server.</p>
  
  <p>Please tell me how I could do this or how I could start with this project.</p>
