\twopagepicture package refining

Question

I have been able to use the \twopagepicture package with success (all margins, appearances, etc.) correspond to what I have been looking for one of my wide figures in the thesis, however, it only gets at the end of the chapter not right after the text where it is supposed to introduce the figure. Is there a particular command I should add to force the figure to the next even/odd pages? I have tried the \clearpage before the next section but still it is.

I am working on a memoir like class that I have found useful for french style memoires. Here is what you can find on my styles file:

And this is how my chapter looks like:

    \section % another section
\end

Could you please help in telling me why the process picture is shifted till the end of the chapter and does not take its place after the \twopagepicture environment? I still am facing a shifting between the left portion of the picture and the right portion (amounting to the caption's space). I totally depend on you figuring out what packages &/or commands are conflicting and resulting in these two issues please.

OK. I seem a bit clearer on this oversize image. But perhaps I'm not getting the required results because I'm not following the advice correctly. Here are some steps I need to clarify: a) When you say "These type of figures are best to insert them manually". You meant insert in the chapter directly? Where is the \twopagepicture command line then? b)You adviced to "Try modifying the \twopagepicture by copying it and renaming it". Where should I copy the file? and HOW could I rename it? c) The commands:

\cleartoevenpage \includegraphics[height=0.95\textheight]{petra} \newpage

should come in the chapter I'm writing? how do I combine these commands with the \twopagepicture command? Is the 0.95 indicative of an "OK" rescaling of my picture? or should I try other ratios until I reach the desired results?

Last, I used the commands as follows in my chapter:

 \cleartoevenpage
    \twopagepicture{b}{p}{Chapitre8/ATMprocessmap.jpg}{Schéma du processus de dévidage des enveloppes de paiement déposées dans les guichets automatiques}
    \label{fig:ATMprocess}
    \pagebreak 
    \cleardoublepage

By trying the \cleartoevenpage before the \includegraphics and the \newpage after do not get me the required results. Notice that I need to omit all paper margins and that still my float goes to the end of the chapter leaving a blank paper at the required section. How could I manage a caption that spans above the two pages?

Answer 1

The reason has to do with an oversize image. As LaTeX cannot fit it on a page it will float to the end. These type of figures are best to insert them manually. You will need to define a different environment for this. Try modifying the \twopagepicture by copying it a renaming it and just comment out the begin{figure} and \end{figure}.

\newcommand*{\twopagepicture}[4]{% copy twopagepicture an comment out
    .....
 %   \begin{figure}[#1]
    ....                
 %    \end{figure}%
 %   \begin{figure}[#1]
    .....     
 %   \end{figure}%
   ......
}

This ensures that the images will be shown exactly where placed.

To have a correctly placed two page spread firstly, one needs a method to clear to an even page, normally I would code it as follows:

\usepackage[strict]{changepage}
\makeatletter
\newcommand{\cleartoevenpage}{%
  \clearpage%
  \ifoddpage\c@page\hbox{}\clearpage\fi}

The second issue to take into consideration, is that the image width is always larger than the \textwidth dimension and hence any scaling must be done on the \textheight. This is important, otherwise you will get a new page.

The even page image is simply placed normally but issuing a \cleartoevenpage before the placement and a \newpage after it, producing the image shown above.

\cleartoevenpage
\includegraphics[height=0.95\textheight]{petra}
\newpage

The odd page image, will have to be shifted to the left by \textwidth.

 \hspace*{-\textwidth}\includegraphics[height=0.95\textheight]{petra}\hspace{1em}

The caption can be placed using a parbox or a minipage. In this case I have used a parbox. If your captions will have more than a paragraph of text, then use a minipage. Depending on the amount of text you have it may look better if you shift it slightly up or down. This can be done either using a vspace command or use a rule (I prefer the latter as I can have a visual clue and only zero the width at the final copy).

  \parbox[b]{0.25\textwidth}{\lipsum*[1-2]\par\rule{1pt}{50pt}}

You can see the rule in the last image below.

Full MWE

\documentclass{book}
\usepackage[left=0pt,right=0pt,top=0.5in,bottom=0.5in]{geometry}
\usepackage{graphicx,lipsum,caption,crop}
\usepackage[strict]{changepage}
\makeatletter
\newcommand{\cleartoevenpage}{%
  \clearpage%
  \ifoddpage\c@page\hbox{}\clearpage\fi}
\begin{document}
First page

\cleartoevenpage
\includegraphics[height=0.95\textheight]{petra}
\newpage
\hspace*{-\textwidth}\includegraphics[height=0.95\textheight]{petra}\hspace{1em}
\parbox[b]{0.25\textwidth}{\lipsum*[1-2]\par\rule{1pt}{50pt}}
\end{document}

Hope this helps.
