Michael, I'm finally getting around to running the new mathtext
examples in mathtext_examples.py. Wow.
As before, I noticed a few things that don't look quite right -- as
usual, some of this may be bakoma font problems, and some may be
correct but just look funny to me, but I'll mention them briefly
- r'$\Delta_i^j$' : the j looks too far to the right
- \frac and \sqrt overbar: the horizontal line appears too thick,
can we make this thinner? THe look pretty good in PS, but too thick
in Agg.
The recursive frac examples are very cool!
- r"$\sqrt[3]{\frac{X_2}{Y}}=5$", I would think the Y should be
under the X, but it is centered under the whole of X_2. Is this how
TeX does it?
- Hinting: you mentioned that the fonts looked so bad because they
lacked hinting. Is this something entirely missing from the fonts or
are we just not making use of it? With hinting, we would have a very
serviceable set of fonts, at least until the STIX fonts come out in
2018
- Kerning -- I may have mentioned this before. I have thought about
implementing autokerning by using the ink extent of the renderered
glyph in the freetype pixel buffer. This would enable us to properly
kern sin(2\pi) for example, if the ) char is in a different font file
than \pi. Over the vertical extent of the \pi, you could locate the
left most pixel ink of the ')' and kern it to the left a bit. Do you
think this is something worth doing, or do you have an alternative?
In the worst case scenario, one could use the spacing operators to fix
stuff up manually for publication, I suppose.
Anyway, very nice work.
JDH
