WPF image manipulation

Question

I have some idea of changing brightness in contrast, but i was wondering had a simple solution for changing brightness and contrast

Answer 1

If you're looking to merely modify the image as it's displaying on screen, here's a tutorial on using HLSL (Pixel shaders) in WPF and one specifically for brightness and contrast

If you're looking for how to manipulate the images in memory and save them to disk, I'll need to look harder, but I'm sure I can come up with something. :)
