[Fontinst] font expansion feature of pdftex

[Ulrich Dirr]

Hi,

recently I've setup some Type-1 fonts for use in TeX with files supplied
by Walter Schmidt (http://home.vr-web.de/was/fonts.html).

Minion, e.g., uses a virtual font pmnr9d which maps to pmnr8r and pmnr8x
respectively. Well, everything worked fine until I decided to use some
small font expansion (up to \pm 2/1000) with pdftex.

Until now I succeeded to use fontinst for this goal only with 'single'
or 'flat' fonts like below.

---snip---
\input fontinst.sty
\declareencoding{FONTSPECIFIC}{uli}
\transformfont{AJenR}{\xscalefont{1000}{\frompl{AJen}}}
\transformfont{AJen+20}{\xscalefont{1020}{\frompl{AJen}}}
\transformfont{AJen+15}{\xscalefont{1015}{\frompl{AJen}}}
\transformfont{AJen+10}{\xscalefont{1010}{\frompl{AJen}}}
\transformfont{AJen+5}{\xscalefont{1005}{\frompl{AJen}}}
\transformfont{AJen-5}{\xscalefont{995}{\frompl{AJen}}}
\transformfont{AJen-10}{\xscalefont{990}{\frompl{AJen}}}
\transformfont{AJen-15}{\xscalefont{985}{\frompl{AJen}}}
\transformfont{AJen-20}{\xscalefont{980}{\frompl{AJen}}}
\bye

and after that
---snip---
\input fontinst.sty
\installfonts
\installrawfont{AJen}{AJenR,AJen}{uli}{LY1}{ajmm}{m}{n}{}
\installrawfont{AJen+40}{AJen+40,AJen}{uli}{LY1}{ajmm}{m}{n}{}
\installrawfont{AJen+35}{AJen+35,AJen}{uli}{LY1}{ajmm}{m}{n}{}
\installrawfont{AJen+30}{AJen+30,AJen}{uli}{LY1}{ajmm}{m}{n}{}
\installrawfont{AJen+25}{AJen+25,AJen}{uli}{LY1}{ajmm}{m}{n}{}
\installrawfont{AJen+20}{AJen+20,AJen}{uli}{LY1}{ajmm}{m}{n}{}
\installrawfont{AJen+15}{AJen+15,AJen}{uli}{LY1}{ajmm}{m}{n}{}
\installrawfont{AJen+10}{AJen+10,AJen}{uli}{LY1}{ajmm}{m}{n}{}
\installrawfont{AJen+5}{AJen+5,AJen}{uli}{LY1}{ajmm}{m}{n}{}
\installrawfont{AJen-5}{AJen-5,AJen}{uli}{LY1}{ajmm}{m}{n}{}
\installrawfont{AJen-10}{AJen-10,AJen}{uli}{LY1}{ajmm}{m}{n}{}
\installrawfont{AJen-15}{AJen-15,AJen}{uli}{LY1}{ajmm}{m}{n}{}
\installrawfont{AJen-20}{AJen-20,AJen}{uli}{LY1}{ajmm}{m}{n}{}
\endinstallfonts
\bye

So finally my question: How can I generate the needed tfm's for pdftex?

Best regards,
