\Grot@start problem with CJK rotation and "dvips -Pdfaxlo"
Danai SAE-HAN (韓達耐)
Last year I sent a similar email (see [1]) about this topic.
I'm currently using CJK4.7.0 (GIT HEAD) and TeXlive2007 on Debian GNU/
Linux unstable.
Here's my problem: CJK (a package to write Chinese, Japanese, Korean,
Thai and other languages in LaTeX) uses PS rotation to get vertical
glyphs. Vertical writing is still used for traditional texts, and some
of the better East-Asian newspapers still use it.
Converting a DVI file to PS shows no problems (for a minimal example
file, see [a]). However, when I use "dvips -Pdfaxlo" to get a G3 fax at
low resolution (204x98), I get some seriously distorted output: the
glyphs are about twice as large but have kept their height.
You can find the output in [2].
I have been told that an improved version of \Grot@start (for a similar
bug in LaTeX3 with code graphics/1896, see [3]) in dvips.def or in the
"graphics" bundle would do the trick. I myself know nothing about
Postscript, so my hands are bound.

BTW, turning glyphs 90 degrees to get vertical writing is a dirty
trick. There are some glyphs -- certain punctuations -- that should
not turn with the text. This is exemplified in the Chinese quotation
marks in your file [2]. The quotation marks should have been kept
unturned. Turning them has made them look weird.

Isn't this a LaTeX & DVI problem rather than a Postscript problem?
Can't you work around it by first converting to PS using dvips and
then coverting the PS to fax format using Ghostscript?
If this workaround succeeds, then your problem is not related to
Postscript, but to dvips. So, this is the wrong place to ask. You
may want to check the "dfaxlo" settings of dvips to see why it's
creating such a problem.

Thank you for your remarks on this one; I'll mail it to the CJK
maintainer.
Some TTF or OTF come with an extra GSUB for glyph substitution, but I'm
not sure if there are any (free) fonts that überhaupt make use of it.
Perhaps a new variant of TeX called XeTeX (with direct TTF support) might
take advantage of this feature, but that's probably something for a
distant future.

Indeed it is; and apparently, "faxlo" and "faxhigh" are only conceived to
work with bitmap fonts, not with Type1 fonts.
Thanks for your info, and sorry for bothering this list. I've sent the
first mail to comp.text.tex as well, and there I got the solution to my
question.

題目:《啼鳥》
作者:歐陽修（１００７－１０７２）
我遭讒口身落此，每聞巧言宜可憎。
春到山城苦寂寞，把盞常恨無娉婷。
花開鳥語輒自醉，醉與花鳥為交朋。
花能嫣然顧我笑，鳥勸我飲非無情。
身閑酒美惜光景，惟恐鳥散花飄零。
可笑靈均楚澤畔，離騷憔悴愁獨醒。
