      Scarpening:
...
    OurImage = Image.JPEG.decode(buff);
    OurImage = OurImage-> 
      apply_matrix(
    	   ({({-1,-1,-1}),
    	   ({-1, 12,-1}),
    	   ({-1,-1,-1})})
    	   );
...
This is not the right forum for these kind of questions. Here we
discuss how to extend Pike, not how to use it. Isn't there still a
Pike user-list at pike@roxen.com? It says so on
http://pike.ida.liu.se/forums/ anyway.
