hm, strange, it seems that
externalfigure is redefined
This is ok

\starttext
\startMPcode
def externalfigure primary filename =
if false :
rawtextext("\externalfigure[" & filename & "]")
else :
image (
addto currentpicture doublepath unitsquare
withprescript "fg_name=" & filename ;
)
% unitsquare
% withpen pencircle scaled 0
% withprescript "fg_name=" & filename
fi
enddef ;
draw externalfigure "hacker.jpg" xscaled 30mm yscaled 20mm ;
\stopMPcode
\stoptext

Re: [NTG-context] MetaPost error

Hi Martin,

The metafun.mem file is svaed in the directory where you run texexec --make
metafun. Thus you need to copy this file into a place where TeX can find it.
e.g. \...\texmf-var\web2c. Run mktexlsr

In order to be able to typeset FLOWcharts do not forget to load the
chart-module

At the beginning of your file just say: \usemodule[chart]

[NTG-context] MetaPost error

2003-09-04 Thread ^Nitram^ 

 Hello

 I'm very newbie in ConTeXt and I can't generate any document with
 MetaPost... For example: \startFLOWchart etc.

 I generate: makemem metafun
 I did texexec --make --alone metafun

 and I still have error:

 initexmf: don't know to dump metafun
 I can't find default mem file!

 Where I can set it or something else do to fix this ?...

 Best regards
 martin
