no.

One way is to let it ignore the picture height by wrapping it into a
\smash instead of \hbox, like \smash{\pdfrefximage 1}. If you want to
move stuff vertically without messing up the rest, write e. g.
\smash{\raise 20pt\hbox{\pdfrefximage 1}}.

(So it's more a plain TeX than a pdftex question.)
