title: Which haskell library will let me save a 2D array/vector to a png/jpg/gif... file?
body: <p>I am playing around with haskell, starting with simple plotting programs to wet my feet. I need a library that will let me save a 2D array/vector to an image file. I don't want to write a list of colors. I want to use containers that are meant for array/vector like computations and can be (well, <em>almost</em>) automagically parallelized. </p>
  
  <p><strong>EDIT</strong> Ability to store color images is a must. </p>
