Dear list,
I have some special needs that requires all the characters be rotated by
90 degrees. I've searched around the web and maybe adding
/FontMatrix [0 1 -1 0 0 0]
to the font descriptor dictionary is helpful. But I can't find a \pdf???
primitive that can achieve this. (Am I wrong about this?)
Another solution might be the "vrt2" font feature. There's no difference
between the results with or without enabling the feature. But
I do see the font has the feature by using the shell command:
otfinfo -f <fontname.otf>
May I put my temporary unsatisfying code here and ask for optimization?
Thanks in advance.
