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
which exist after taking difference between two images, getting sum of all
pixels and area of pixels that are in that image etc.

please guide me regarding this...
