Hi Jim,

I’m afraid that this is a too generous statement.

https://www.pragma-ade.com/general/qrcs/setup-en.pdf#page=218 shows
which keys and values \setupexternalfigure allows.

I would say, that the offset and frameoffset don’t seem to be available
in \setupexternalfigure.

I hope it is clear now.

To get offset in the frame of the image, you need a different frame from
the external figure itself (or so it seems).

I hope it helps,
