"Dimension too large" error with tikz graphic using tikzmark when document gets too many pages
(To long for a comment). It is a bug in tikzmark and related to the next page option. It multiplies \pgf@y by the page number, and with a large enough page number it explodes.
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{tikzmark}
\tikzset{
next page=below,
}
\begin{document}
\setcounter{page}{30}
\tikzmark{blub}\tikz[remember picture]\draw(pic cs:blub);
\end{document}
Here's my proposed fix. To try it out, put it between \makeatletter ... \makeatother
in your preamble after loading the tikzmark library.
It's entirely possible that I don't understand how \numexpr
or dimensions work, but the idea is sound.
\tikzdeclarecoordinatesystem{pic}{%
\pgfutil@in@,{#1}%
\ifpgfutil@in@%
\tmk@labeldef#1\@nil
\else
\tmk@labeldef#1,(0pt,0pt)\@nil
\fi
\@ifundefined{save@pt@\tmk@label}{%
\tikz@scan@one@point\pgfutil@firstofone\tmk@def
}{%
\pgfsys@getposition{\csname save@pt@\tmk@label\endcsname}%
\save@orig@pic%
\pgfsys@getposition{\pgfpictureid}\save@this@pic%
\pgf@process{\pgfpointorigin\save@this@pic}%
\pgf@xa=\pgf@x
\pgf@ya=\pgf@y
\pgf@process{\pgfpointorigin\save@orig@pic}%
\advance\pgf@x by -\pgf@xa
\advance\pgf@y by -\pgf@ya
\pgf@xa=\pgf@x
\pgf@ya=\pgf@y
\pgf@process%

\advance\pgf@xa by \pgf@x
\advance\pgf@ya by \pgf@y
