LaTeX forum ⇒ Others ⇒ Insert pdf file in LuaTex (not LuaLaTex or any ...LaTeX)

Hi there.

I wonder how to insert an existing pdf file into a LuaTex document.
I know how to insert images (\saveimageresource, \useimageresource, ...).
I know I can insert a pdf file with exact these image functions, but I don't know how to selcet special pages out of this pdf file.
I know the LaTex package pdfpages can do that, so it might be possible for plain tex (LuaTex), too.
Can anyone help?

Regards
Peter

I found the answer by myself in the PdfTex manual:

\saveimageresource page <page number> {<my-pdf-file>}
\useimageresource width <width>\lastsavedimageresourceindex

LuaTex commands \saveimageresource and \useimageresource are equivalents to PdfTex comands \pdfximage and \pdfrefximage.

Thanks and greetings from Germany
