Another issue is that I am implementing a primitive requrested by Cho, to grab the BBox of an included pdf.
What's the purpose? The knowledge of width and height is important (graphicx, pdfpages, ...). By putting \pdfximage into a box these values are easily available (see pdftex.def). I would be interested, in which case the exact offset must be known.
there are users who want to use pdftex to produce dvi code and use dvipdfmx to produce the pdf; now that pdftex is the main tex engine, we need to address both audiences.
dvi users need to know the width and height of the graphics that TeX can reserve the needed place.
(btw, this feature should therefore also work when pdfoutput=0)
Ah, interesting.
usually the numbers returned are directly passed into the special that dvipdfmx uses for inclusion
* dvipdfm: CTAN:dviware/dvipdfm/dvipdfm-0.13.2c.pdf
Section "8.1 Epdf" explains the epdf special that can
embed the first page of a pdf file, but I didn't found
any need of bounding box information.
* dvipdfmx: CTAN:dviware/dvipdfmx/README
There is a section "6. DVI Specials" and
"6.2. Additions to Dvipdfm's pdf: Special",
but unhappily both sections are empty.
Is there a better source of information?
Yours sincerely
