Yes.  It would.  I hadn't known thei function was available, even 
though I had read the pict manual some time ago.

But the recursive scan over the entire set of subpicts might take some 
time.

But this is may be easier than the technique with the blank pict.

Yes ... I can calculate the size of the new bounding box from the sizes 
of the old picts and the offsets dx and dy, then make the blank pict 
accordingly, and then use pin-over and pin-under to make pin each
original pict to the blank pict.

Yes, that would work.  It would even handle the case where I wanted to 
pin more than two picts together.

(Now why didn't I think of that?)

Thank you.

It might affect other Picts inside, but if there aren't any, then yes.

Wouldn't `(panorama (pin-over base dx dy pict))` handle this?

You can cc-superimpose with a blank pict (perhaps that you get via
ghost/launder). Does that help?

[racket-users] pinning in pict

[Hendrik Boom]

Isn't there something like pin-over and pin-under which extends the 
bounding
box to contain both the 'base' and the pict being written over ot 
under it?

The version with dx and dy would be fine for me, especially if dx and/or 
dy can be negative.
