 Hi,
I try to understand how this macro by testing a simple example. Why pdf file
is empty ?
This question follows my question Cover page (Metafun)

Thank you.

Do you have pstoedit installed?

Anyway, there is a new mechanism that doesn't depend on additional 
programs:

% outlinetext   (text) transformations ;
% outlinetext.d (text) (draw options) transformations ;
% outlinetext.f (text) (fill options) transformations ;
% outlinetext.b (text) (draw options) (fill options) transformations ;
% outlinetext.r (text) (fill options) (draw options) transformations ;

\starttext

\startMPdefinitions
     let graphictext = new_graphictext ;
\stopMPdefinitions

\startMPpage

     draw outlinetext.b
         ("\framed[align=normal]{\input{tufte}}")
         (withcolor .5white)
         (withcolor red withpen pencircle scaled 1/10)
         xsized 10cm ;

\stopMPpage

\startMPpage

     draw outlinetext.r
         ("\framed[align=normal]{\input{tufte}}")
         (withcolor red withpen pencircle scaled 1/10)
         (withcolor .5white)
         xsized 10cm ;

\stopMPpage

\startMPpage

     draw outlinetext.d
         ("\framed[align=normal]{\input{tufte}}")
         (withcolor .5white)
         xsized 10cm ;

\stopMPpage

\startMPpage

     picture p ; p := outlinetext.p("PX") ;

     for i within p :
         draw i withcolor red withpen pencircle scaled 1/10 ;
     endfor ;

\stopMPpage

\stoptext

Hi Hans,

Do you have pstoedit installed ?


root@debian:/home/fab# apt-cache search pstoedit
libpstoedit0c2a - PostScript to editable vector graphics library (runtime
files)
root@debian:/home/fab#

I compile the file test.tex  with  context test.tex

Hi Hans,
I installed pstoedit :

Version: 3.62-2+b3
Depends: libc6 (>= 2.2.5), libpstoedit0c2a, libstdc++6 (>= 4.1.1),
ghostscript
Suggests: xfig | ivtools-bin | tgif | transfig
Description: PostScript and PDF files to editable vector graphics converter
 pstoedit converts Postscript and PDF files to various editable
 vector graphic formats including tgif, xfig, PDF graphics, gnuplot format,
 idraw, MetaPost, GNU Metafile, PIC, Kontour and flattened PostScript.
Homepage: http://www.pstoedit.net/

I compiled the file as this : "context test.tex" but it is still empty.
Thanks,
Fabrice
