Create landscape image page in pdf, without breaking text flow

Question

Here is an MWE. If you compile this to PDF, you get a half-empty page on the first page, as the last part of the text doesn't come up, but is forced onto a new page. Compare this with the same thing, but with the \begin{landscape} removed.

\documentclass[11pt,a4paper,twoside,openright]{book}
\usepackage{graphicx}
\usepackage{pdflscape}

\begin{document}

\chapter{blah}

blah blah

\section{something}
\begin{landscape}
\begin{figure}[p!]
  \includegraphics{figures/someimage.pdf}
\end{figure}
\end{landscape}


A whole lot more text.

\end{document}

Thing is, I really need a full page landscape for this particular figure, because it has so much detail. Is there a way to do this that doesn't break the text flow so badly? (perhaps using another package? the pdflscape documentation is horrendous - 14 pages, and only two lines dedicated to usage.)

Answer 1

landscape does \clearpage you don't want that, just use a figure and rotate the image with

\rotatebox{90}{\includegraphics...} 

or if you want the caption on its side as well use the sidewaysfigure environment from the rotating package

Answer 2

Package afterpage does the trick. If the environment landscape is put into \afterpage then the landscape page is inserted after the current page is completed.

\documentclass[11pt,a4paper,twoside,openright]{book}
\usepackage{graphicx}
\usepackage{pdflscape}
\usepackage{afterpage}

\begin{document}

\chapter{blah}

blah blah

\section{something}
\afterpage{\begin{landscape}
\begin{figure}[p!]
  \includegraphics{figures/someimage.pdf}
\end{figure}
\end{landscape}}

A whole lot more text.

\end{document}
