Hallo!

I use the following test-file

--------------------test.tex-------------------------
\usetypescriptfile [type-bunt]
\usetypescript [Bunt]
\setupbodyfont [Bunt]
\starttext
\chapter{Test}
{\cg Gottes.}
\stoptext
---------------------------------------------------------

and this typescript

------------------type-bunt.tex--------------------
\starttypescript [calligraphy] [bunt] [name]
  \definefontsynonym [calligraphy] [bu1000]
\stoptypescript

\starttypescript [calligraphy] [bunt] [size]
  \definebodyfont [5pt,6pt,7pt,8pt] [cg]
    [tf=bu0900 sa 1]
  \definebodyfont [9pt] [cg]
    [tf=bu0900]
  \definebodyfont [10pt] [cg]
    [tf=bu1000]
  \definebodyfont [10.95pt] [cg]
    [tf=bu1095]
  \definebodyfont [12pt] [cg]
    [tf=bu1200]
  \definebodyfont [14.4pt] [cg]
    [tf=bu1440]
  \definebodyfont [17.28pt] [cg]
    [tf=bu1728]
%  \definebodyfont [20.7pt] [cg]
%   [tf=bu2074]
  \definebodyfont [20.74pt] [cg]
    [tf=bu2074]
  \definebodyfont [24.88pt] [cg]
    [tf=bu2488]
\stoptypescript

\starttypescript [Bunt]
  \definetypeface [Bunt] [cg] [calligraphy] [bunt] [bunt] [encoding=ec]
\stoptypescript
---------------------------------------------------------

to use a metafont which was designed in the 8 sizes
(9,10,10.95,12,14.4,17.28,20.74 and 24.88pt)
Fontsizes lower then 9pt should downscaled useing the 9pt font. (not testet
yet!)

Problems:

1. The bodyfont is 12pt per default, so pdftex uses bu1200.tfm to calculate
the text.
    The chaptertitle is then in 20.74pt, but pdftex doesn't use the
existing font bu2074.tfm, but
    scales the bodyfont by a factor of 1.728.
    As a result, mktexpk calculates the pk files bu1200.600pk and
bu1200.1037pk,
    and not bu1200.600pk and bu2074.600pk.

    I tried to include the commentet two lines in the typescript, because I
always found written sizes
    in context with one digit behind the point, but the result is negativ
too.

2. The log-file contains the following:

    > ) (./type-bunt.tex)
    > fonts          : [calligraphy] [bunt] [name,default,ec,special]

    My typescript neighter contains a section [ec] nor a section [special].

    What are they for? Why are they referenced in the log.

    > ) (./type-bunt.tex
    > bodyfont       : bodyfont 7.6pt is defined (can better be done
global)
    > bodyfont       : bodyfont 7.6pt is defined (can better be done
global)
    > bodyfont       : bodyfont 5.4pt is defined (can better be done
global)
    > ....

    lots of this lines. Most exist doubly, some not.
    What is this? I have not redefined 7.6pt or 5.4pt ...?
