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 chang开发者_如何学Goe 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.
