However, since we cannot produce a horizontal or vertical segment out of a diagonal stem, the stem cannot be blue zoned, e.g. the top and the bottom of 户. To solute the problem, I suggest to treat the extremas of every contours in a glyph as edge lines. Then we can blue zone the edges so that diagonal stems can also be aligned at top and bottom. What do you think?
