Change pixels to fill with color in a WPF image

I'm trying to fill an area of an image in WPF. Something similar to the bucket in Paint. How should I do this? I'm thinking of getting the pixel color under the mouse, and change all the pixels with the same color near. Is there a simpler way?
What should I use? WriteableBitmap?
Thank you
Yes, WriteableBitmap is the best way to go on this one IMHO.
