the .NET Image Tools library is a good starting point. The ImageTools.Filtering namespace includes some filters that may do what you are looking for.

Just a guess, but how about using layering and transparency; for example:

Rectangle { Background = black} Image Rectange { Background = white }

By changing the relative opacity of the image and foreground (white) rectangle, I would imagine you'd get a reasonable simulation of changing contrast.

Be interested to know if this works...

I'm not sure about that. In my case, I need to be sure, so no. But not a bad ideia. – alansiqueira27 Mar 09 '11 at 16:33
