About the other bluezones, it's difficult for me to recognize
remarkable improvement. Talking about the height/width proportion
of 想意, the non-autofitted results look like same size, but
both (old/new) autofitted results look like different size
(rather, 想 looks like as taller than 意).
That's obviously because we failed to detect a top segment/edge for
the 2 glyphs. Therefore we cannot 'lift' the top edges of the glyphs.
At the same time, the first detected horizontal edges are grid-fit
to the lower grid. The result is a pressed down perception on the
top of the glyphs.
Cannot do much with blue zone before we can detect all the ending of a
stem and also the extrema of a diagonal stem. It's not a problem of
the blue zone fitting.
For CJK glyph, There are alway many diagonal stems that needed to
be fit with blue zones. 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?
