[NTG-context] Using Postscript Type 1 fonts in ConTeXt/XeTeX?

20 Jan 2008

      Hi,

I am fairly new to both ConTeXt (and XeTeX) but I've already been very
impressed with the active user community and the amount of
documentation available, as well as with the sheer userfriendliness of
ConTeXt when compared to LaTeX. Now I'm trying to get into fonts, but
activating a Postscript Type 1 font seems to go beyond my abilities
and the wiki documentation on
http://wiki.contextgarden.net/Fonts_in_XeTeX . Perhaps anybody can
help?

I have a Postscript type 1 font family called Eco, consisting of
Eco101Roman, Eco102Italic, Eco301Bold and some others. FontBook shows
these names identically as PostScript name, Full Name and Family name
(which means Fontbook is unaware that they are a family, but this is
not the topic here).

The fonts can be used with any Mac application and they also work fine
in a LaTeX-fontspec-XeTeX combination: the following minimal LaTeX
file produces the text as desired in Eco101Roman.

     1  %!TEX TS-program = xelatex
     2  %!TEX encoding = UTF-8 Unicode
     3  \documentclass[12pt]{article}
     4  \usepackage{fontspec}
     5  \defaultfontfeatures{Scale=MatchLowercase}
     6  \setromanfont[Mapping=tex-text]{Eco101Roman}
     7  \setsansfont[Mapping=tex-text]{Skia}
     8  \setmonofont{Courier}
     9  \author{Roland}
    10  \title{XeTeX test}
    11
    12  \begin{document}
    13          \maketitle
    14          \section{This is a new section}
    15          Let's try to \emph{write} this.
    16
    17  Lorem ipsum dolor sit amet, consectetur adipisicing elit,
    40  \end{document}

On ConTeXt however, I cannot get the font to be recognised. Please see
my testfile below, in which I tried to
(a) compile it with a self-installed TrueType font (which works)
(b) tried to select Eco101Roman directly (which produces a ** ERROR **
Invalid font) and
(c) tried to select the font through a typescript (which produces a
"Metric (TFM) file or installed font not found.")

What am I doing wrong? How can I get these fonts to work (and make
ConTeXt treat them as a proper family too?)

Looking forward to your ideas!
Roland
