How to make shaded pages and still see memoir's trim frame?

Question

I am using memoir and I have the showtrims setting activated which I want visible on my pages. I am trying to toggle shading of entire pages and so far I am not having any great success. I have looked around but not seen anything obvious that can help me but this is what I have managed to come up with:

\documentclass[showtrims, 10pt]{memoir}
\usepackage{lipsum}
\usepackage{eso-pic}

\stockaiv
\settrims{20mm}{20mm}
\trimFrame

\pagesmallroyalvo

\setbinding{4mm}
\settypeblocksize{*}{24.5pc}{1.618}
\setlrmargins{*}{*}{1.5}
\setulmarginsandblock{6pc}{7pc}{*}
\setmarginnotes{6pt}{6pc}{12pt}
\strictpagecheck
\setlength{\topskip}{1.6\topskip}
\checkandfixthelayout

\begin{document}
\lipsum[1-4]

\newpage
\AddToShipoutPictureBG{
  \AtStockUpperLeft{
    \colorbox{cyan}{\vspace* \stockheight \hspace \stockwidth}
  }
}

\lipsum[1-4]

\AddToShipoutPictureBG{
  \AtStockUpperLeft{
  }
}
\newpage
\lipsum[1-4]


\end{document}

However there are two problems.

1. I can't seem to manage to fill out the page in the vertical direction. Only in te horizontal.

2. I don't seem to be able to turn it off by changing the ship out picture again.

What am I doing wrong? Or is there a better way of doing this?

Answer 1

You could use the background package; the \NoBgThispage commands allows you to suppress the color for the pages in which the command is used:

\documentclass[showtrims, 10pt]{memoir}
\usepackage{lipsum}
\usepackage{ifthen,background}

\stockaiv
\settrims{20mm}{20mm}
\trimFrame

\pagesmallroyalvo

\setbinding{4mm}
\settypeblocksize{*}{24.5pc}{1.618}
\setlrmargins{*}{*}{1.5}
\setulmarginsandblock{6pc}{7pc}{*}
\setmarginnotes{6pt}{6pc}{12pt}
\strictpagecheck
\setlength{\topskip}{1.6\topskip}
\checkandfixthelayout

\SetBgScale{1}
\SetBgAngle{0}
\SetBgVshift{10pc}
\SetBgColor{cyan}

\makeatletter
\AddEverypageHook{%
  \ifthenelse{\isodd{\value{page}}}{\SetBgHshift{8pc-1.5pt}}{\SetBgHshift{5pc-3pt}}
  \SetBgContents{\rule{\paperwidth}{\paperheight}}%
  \bg@material
}
\makeatother

\begin{document}

\lipsum[1-4]

\newpage\NoBgThispage
\lipsum[1-4]

\newpage
\lipsum[1-4]

\end{document}

Compile the document twice.

Using the above code, only the actual page will receive a colored background; increasing the width and height of the rule, you can obtain some bleed. Here's the result obtained by replacing \SetBgContents{\rule{\paperwidth}{\paperheight}} with \SetBgContents{\rule{\dimexpr\paperwidth+3cm\relax}{\dimexpr\paperheight+3cm\re‌​lax}} in the code above:

Answer 2

You can use \pagecolor to specify the background color of the page, and \afterpage from the afterpage package to reset to \nopagecolor after the current page is output.

Known Issues:

• As noted by @jonalv this solution places itself on top of the frame showing the paper size, so is not a good solution when you require both the frame and page color.

Code:

\documentclass{article}
\usepackage{afterpage}
\usepackage{xcolor}
\usepackage{lipsum}% for dummy text

\begin{document}
\pagecolor{yellow!20}\afterpage{\nopagecolor}
\lipsum[1-11]
\pagecolor{blue!20}\afterpage{\pagecolor{red!20}}
\lipsum[1-10]
\end{document}

Answer 3

I changed the colorbox to a \rule and anchored it at the bottom left, instead of the top left.

To clear it from subsequent pages, I used \ClearShipoutPictureBG

\documentclass[showtrims, 10pt]{memoir}
\usepackage{lipsum}
\usepackage{eso-pic}

\stockaiv
\settrims{20mm}{20mm}
\trimFrame

\pagesmallroyalvo

\setbinding{4mm}
\settypeblocksize{*}{24.5pc}{1.618}
\setlrmargins{*}{*}{1.5}
\setulmarginsandblock{6pc}{7pc}{*}
\setmarginnotes{6pt}{6pc}{12pt}
\strictpagecheck
\setlength{\topskip}{1.6\topskip}
\checkandfixthelayout

\begin{document}
\lipsum[1-4]

\newpage
\AddToShipoutPictureBG{
  %\AtStockUpperLeft{
  %  \colorbox{cyan}{\vspace* \stockheight \hspace \stockwidth}
  %}
  \AtTextLowerLeft{% put it at the left bottom of the text area
  \color{cyan}\rule{\textwidth}{\LenToUnit\textheight}%
  }%
}

\lipsum[1-4]


\newpage
\lipsum[1-4]
\ClearShipoutPictureBG{}


\end{document}

Answer 4

Based on cmhughes answer I came up with this solution which has all the signs of an ugly hack:

\documentclass[showtrims, 10pt]{memoir}
\usepackage{lipsum}
\usepackage{eso-pic}
\usepackage{transparent}

\stockaiv
\settrims{20mm}{20mm}
\trimFrame

\pagesmallroyalvo

\setbinding{4mm}
\settypeblocksize{*}{24.5pc}{1.618}
\setlrmargins{*}{*}{1.5}
\setulmarginsandblock{6pc}{7pc}{*}
\setmarginnotes{6pt}{6pc}{12pt}
\strictpagecheck
\setlength{\topskip}{1.6\topskip}
\checkandfixthelayout

\begin{document}
\lipsum[1-4]

\newpage
\AddToShipoutPictureBG{
  %\AtStockUpperLeft{
  %  \colorbox{cyan}{\vspace* \stockheight \hspace \stockwidth}
  %}
  \AtStockLowerLeft{% put it at the left bottom of the text area
  \color{cyan}\transparent{0.5}\rule{\stockwidth}{\LenToUnit\stockheight}%
  }%
}

\lipsum[1-4]


\newpage
\lipsum[1-4]
\ClearShipoutPictureBG{}


\end{document}

This solution has the disadvantage that the actual color needs to be calculated by taking the transparency into account so it's not the ideal solution...
