Hello All,
      i have an application where i am comparing two images and highlighting
the difference part in a separate image. I am using ImageChops subtract
method. Here is the code:

        diff = ImageChops.subtract(file1,file2,0.3)

But i want to find other image statistics such as finding number of pixels,
getting sum of all pixels and area of pixels that are different etc.

please guide me regarding this...
