In particular, the second pass from bottom to top seems to have no effect and proximity to things below is lost (or always set to zero?). {{{ gdal_proximity.py small.tif out.tif -ot Byte }}} Note that the out.tif is all zeros but it should have increasing proximities from the middle up as the bottom of the source image is non-zero.
