title: What's the easiest way to display an image in C/Linux?
body: <p>I'm quite comfortable with C for numerical computation, but not for graphical programming.  I have a Nx by Ny by 3 RGB matrix in a command-line program for linux (gcc, ubuntu) and I want to pop up a window with it as an image. What's the easiest way to do this?  It has to be relatively quick because I'll be updating the image frequently.</p>
  
  <p>Thanks</p>
