 well, if you can find out what the problem is we can fix it (i dunno if
 it's in dvips or in the special driver of context; maybe something
 changes in dvips - which is probably only tested with latex -)

Probably I won't be able to find out the details, but I can make some
tests. I can already say, that dvips and xdvi behave the same: only white
area instead of the figure.
Cheers, Peter

 Hello,

 \externalfigure[test-img][width=0.5\textwidth]

 Or is there already such (undocumented) feature?

  
   
 \clip[nx=10,ny=20,x=2,y=4]{}

 and alike (grep for clip)

 Peter was asking for something different, I believe.

 \clip do the thing well but you have to measure a bb somewhere, e.g. in 
 GhostView. Since \externalfigure have to know bb then an option 'clip' 
 can do that without manual measuring. There might be even en extension: 
 apart from 'clip' option there could also be 'bb=10 20 100 200' option 
 for overwritting original boundingbox. Clipping a figures would be a bit 
 more strightforward.
   
i dunno what the intended effect is but here's an example

\starttext

\startuseMPgraphic{test}
draw fullcircle scaled 4cm withpen pencircle scaled 1cm ;
setbounds currentpicture to boundingbox fullcircle scaled 4cm ;
\stopuseMPgraphic

\ruledhbox{\useMPgraphic{test}}

\vskip3cm

\ruledhbox{\clip{\useMPgraphic{test}}}

\stoptext

I see, I did not realize such simple usage of \clip (without options). 
That do exactly what was thinking about. One character of typing 
difference between:

   \clip{\externalfigure{test}}

and

   \externalfigure[clip]{test}

is not crutial:) So sorry for noise.

But as far as I know, \clip works only with left|top,width|height 
params. Could right|bottom be added (assuming at least one from 
left-width-right and top-height-bottom is missing - if not width|height 
is ignored)? Or there is again some secret that I missed?

Thanks! I tried different options (x=1,y=1 or width=0.5\textwidth etc) but
whenever I use \clip[...]{\externalfigure...} the figure disappears.

What options should I use, to clip just exactly to the bounding-box (as the
LaTeX clip-option)?
