Taco has already answered the question, but if you just want to insert the 
image as a background, there is no need to do so via MP. The following 
also works:


\setupexternalfigures[location={local,global,default}]
\setupbackgrounds[page][background={Bkg}]

\defineoverlay[Bkg][{\externalfigure[hacker.png][width=\overlaywidth,
height=\overlayheight]}]

\starttext
  Ahoj

Use

  draw externalfigure “hacker.png”;

Best wishes,

[NTG-context] Problem inserting image within MP

2019-10-10 Thread context 

Hello,

this is a probably basic question, but the following code doesn't 
compile:



\setupbackgrounds[page][background={Bkg}]

\defineoverlay[Bkg][\useMPgraphic{Bkg}]

\startuseMPgraphic{Bkg}
  externalfigure "hacker.png";
\stopuseMPgraphic

\starttext
  Ahoj
\stoptext


with:

"

picture

! Isolated expression.

;
<*>  externalfigure "hacker.png";
;
I couldn't find an `=' or `:=' after the
expression that is shown above this error message,
so I guess I'll just ignore it and carry on.
"

I just want to insert a picture from within MP code. What am I doing 
wrong?


Best regards,

Lukas
