Hi, ConTeXters

I'm playing some Chinese vertical typesetting. Mr. Wolfgang Shuster helps me
a lot about it.

In vertical typesetting, the top of each leading Chinese characters at each
column are aligned horizontally. But if we changed the size of the bodyfont
of some characters and they could wrap to the next column, then the top of
the wrapped texts are not aligned with the other columns. So we can give
them a raise, but it is not so easy to calculate the dimension to be raised,
for ConTeXt will give every Chinese a \strut and makes the original height
and depth unavailable. Since we can aligned the \strut-ed characters
precisely, the real characters are not.

Can Hans or other TeXperts give me a nice solution?

In fact, I think in vertical Chinese, we should move the baseline to the top
of the character. and make it with height=0pt and depth=width

-- 
Sincerely yours,
Chen
