Maybe I am just too tired, but I simply can't explain what is going on.
The file
\documentclass[a5paper]{scrbook}
\usepackage{lipsum}
\begin{document}
\lipsum
\end{document}
produces A4 sized pdf pages (when run with pdflatex) with text only in the upper left corner, while
\documentclass[a5paper]{scrbook}
\usepackage{tikz}
\usepackage{lipsum}
\begin{document}
\lipsum
\end{document}
produces the proper A5 pages. Why is that?
Knuth in the TeXBook gave an example of "poor man's bold," (The TeXbook, p. 386) which can be typeset obtained by overprinting the normal weight symbol with slight offsets.
As he says:
The results are somewhat fuzzy, and they certainly are no match for the real thing if it's available; but poor man's bold is better than nothing, and once in a while you can get away with it.
Here, one can use a similar technique and the code is shown below:
\documentclass{article}
\usepackage{graphicx,xcolor}
\usepackage{amsmath}
\def\PoorManContour#1#2#3{\leavevmode
\setbox0=\hbox{{#1}}%
\color{#3}\kern-.002em\copy0\kern-\wd0
\color{#3}\raise-.04em\copy0\kern-\wd0
\color{#3}\lower.04em\copy0\kern-\wd0
\color{#3}\raise0.04em\copy0\kern-\wd0
\color{#2}\raise-.012em\copy0\kern-\wd0
\color{#2}\kern.06em\copy0\kern-\wd0
\color{blue}\kern-.020em\lower.003em\box0
}
\begin{document}
\colorbox{gray!5}{\scalebox{5}{\PoorManContour{$\sqrt{\dfrac{A^3_i}{B^2}}$}{gray!60}{gray!60}}}
\end{document}
To achieve the best results possible one has to kern in small steps for possibly twenty steps or so. For simplicity, I have not done that. In the final version, you need to adjust the colors to suit, possibly changing the shading to white.
Edit
After reading Jan's comment below I read the manual and true, as the commenter said the easiest way to achieve what the OP wanted is to include the package without an option i.e., \usepackage{contour}. Helps to RFM!
For the scrartcl class and others in this family, the default is not to set the paper size infomation in the output file, just to set the LaTeX lengths; under pdflatex the output file then gets the dimensions of the system default. This can be changed by adding the option pagesize to the documentclass. For example, choosing a non-standard size:
\documentclass[paper=b5,pagesize,DIV=12,twoside]{scrartcl}
\begin{document}
Test.
\end{document}
the viewer reports that the pdf is 17.6x25.0cm, whereas without pagesize on my system it is 21.0x29.7cm (I need to close my viewer between file changes to see a reported change of information).
If you want to move this pagesize setting out of the file, not sure that is a good thing, then you can create a typearea.cfg containing
\KOMAoptions{pagesize}
placed either in the current directory of the project, or in the local texmf tree (where will be picked up by all your scrartcl documents).
Best Answer
Use the option
pagesize:You may specify
pagesize=pdftexor set it todvipsorauto. This option takes care of setting either pdf lengths or putting\specialcommands into the dvi file, see the manual.Even without, in such cases (other classes for instance ) you don't need TikZ.
takes care of the correct paper size, as well as
\usepackage{hyperref}. Apparently the pdf paper size has not been correctly set (or use the default of the distribution) but geometry and hyperref fix that.Alternatively, without any option or package this would fix it for pdfLaTeX:
