hi all

I made a MetaPost graphic and I want to use this graphic for a background.
The graphic is too large and I want to clip it to the size of 84mm width and
54mm height. With
"clip currentpicture to unitsquare xyscaled (86mm,54mm)"

I get the size I wanted but the clipped field should be placed in the center
of the currenpicture. I tried:

"clip currentpicture to unitsquare xyscaled (86mm,54mm) shifted center
boundingbox currentpicture"

but that became not the effect I wanted.How can I shift the clipping area to
the center of the currenpicture?

thx for help
