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.

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

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

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

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.

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.
