I can not manage it with sed only, but this works as well, using awk instead:
. sy pdfinfo @$1 | \
awk '/Page size/ {print ".nr pdf-wid \\(p;" $3 "\\)\\n.nr pdf-ht \\(p;" $5i
"\\)\\n"}' \
> /tmp/pdfpic\n[$$]
It depends on pdfinfo putting the numbers at pos $3 and $5
If you don't like to change pdfpic.tmac I could make a small script "genpdf"
which calls convert and removes all \n : sed 's/\0//g'
