Hi, Henning Thielemann. Thanks for your help. That is usful.
I have wrote the target function like this, and tested. mkBlocks (w,h) = map concat . concat . transpose . chop h . map (chop w) Hi, Dr. Janis Voigtlaender. This is not a homework, though likely to be one. I just use Haskell to write tools being used in my work. This is one of them. I need to locate the difference between my coded image and standard coded image. And both coded in 16x16 macroblocks. That is why I ran into this problem. Anyway, thanks for your advice. ------------------ L.Guo 2007-06-14 _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
