smooth a 2 color image

I have an image in 2 colors (b&w, no greys). How do I smooth the edges while maintaing 2 colors?

For example, suppose the following represents a segment of the image (where B = black pixel and W = white pixel)

WWWBW WWWBW
WBBBW
WWWBW
WWWBW

i would like the image to be like this:

WWWBW WWBBW
WBBBW
WWBBW
WWWBW

(the 3rd pixel in line 2 and the 3rd pixel in line 4 changed from W to B, thus smoothing from edge from line 1, pixel 4 to line 3, pixel 2)

Most filters don't operate on 1-bit images. Would it be feasible for you to convert your image to grayscale, use a smoothing filter, and then converting back to 1-bit?
