"separate piece" means the per-page splitting?
Or, spliting a large page into small fragments
(e.g. from A3 page to 2 x A4 pages)?

Both can be realized by cairo output device, but
the cairo output device completely rewriting
the content (e.g. font names are changed, pictures
are extracted and losslessly-recompressed), so
some people may complain "it's not what I want".

# In my case, I don't use poppler for such purpose.
# I use pdftk command line tool.

At present, I think, PDFDoc object is created
by opening pathname for PDF file or reading
a stream to PDF file. PDFDoc object cannot be
created by subsetting other PDFDoc.
