This transformation lacks symmetry which makes it suspect. But currentlyCurrently there's nothing in the task description to help us understand this issue. It's difficult to see how this corresponds to a contour of the original image, but if the above were rotated counterclockwise 90 degrees, the inner region of zeros does correspond to the original image:

In contrast, the Wren and Phix solutions identify a path with length 11 composed of 10 unique coordinates which would probably correspond to these positions (or maybe this should be shifted up and to the left by one grid coordinate? I'm guessing because I don't know whether the 0,0 coordinate would correspond to the upper left hand corner of the bitmap or if it would be outside the bitmap):

Again, this lacks symmetry. But this result is not comparable to the other result because the starting bitmap was different (and also was not symmetric). This one, at least, seems to correspond more closely to the shape of the initial bitmap.
