Here's how I'd do it:
Edit->select by color
Select the black color. Copy it to the clipboard.
Select the white color. Fill it in black or invert the color (same effect).
Paste the black from the clipboard, invert the color (image->colors->invert
I think). Finally, line things up if the paste didn't go where it's supposed
