Refer to a specific page of a multipage object

Question

I am sure the answer to this exists somewhere here, but I am just not able to find it. I have many multipage figures/tables etc. in my document. I would like to be able to refer to a specific page of a multipage object. Using ~\pageref{somelabel}, I am able to refer to the first page of the object. If I know that my reference of interest is say, on the 5th page, how do I get ~\pageref{somelabel} to link to the 5th page of this multipage object. Thanks in advance for any help!

Answer 1

Here's a mock-up of how you could go about obtaining your hyper-linked page references.

Assume the following is your multi-page image (or table):

\documentclass{article}
\usepackage{lipsum}% http://ctan.org/pkg/lipsum
\begin{document}
\lipsum[1-50]
\end{document}

This creates a 10-page document containing "stuff." Now you can include this in your main document in the following hypothetical way using pdfpages:

\documentclass{article}
\usepackage{lipsum}% http://ctan.org/pkg/lipsum
\usepackage{pdfpages}% http://ctan.org/pkg/pdfpages
\usepackage{hyperref}% http://ctan.org/pkg/hyperref
\newcounter{myimage}
\begin{document}
\lipsum[1-2]
See page~\pageref{myimage-5} for more details.
\includepdf[pages=-,pagecommand={\stepcounter{myimage}\label{myimage-\themyimage}}]{lipsum50}
\lipsum[1-2]
\end{document}

The above creates a 12-page document with the 10-page image on pages 2-11. Page X receives the label myimage-X via pagecommand. pagecommand steps some counter (myimage) and also inserts a unique label. Then you can refer to the specific page of a multi-page image using \pageref{myimage-<page>} like in my example:

\pageref{myimage-5} refers to page 6. For multiple multi-page images/tables, you need to reset the counter before each inclusion (\setcounter{myimage}{0}) and also provide a unique label for each image/table. The latter requirement is usually the default when working with labels, so shouldn't influence your workflow.

The above discussion involves the inclusion of multi-page "images." Using multi-page tables in the longtable sense you can insert \label inside the table where you want to obtain the exact reference you need for the page it's on.
