Thanks, I'll test that.

A bizcard[1] is a picture in which you \put() things.

At the back of my cards[2] I place 2 images around the barcode.

The barcode is centered, vertically and horizontally, the images are
centered in the remaining spaces.

To do this, I need to know the size of the barcode.

Now you give me an answer to generated a tight image, so I can use
\includegraphic in a savebox and define to lengths with \settowidth and
\settoheight.

Regards.
