I don't know why you haven't had anyone comment on your program yet.  Me, I am not into graphics, very much, so I can't give you any good advice or suggestions.  However, it seems to do exactly what you say, very well. 

Please continue with your stated intentions, and keep posting, here.  A guru or two should, hopefully, note your good efforts and join in with some helpful ideas!
