[OS X TeX] texshop and preview

[Victor Ivrii]

The following example was posted in MacOSX TeX mailing list

\documentclass{article}
\usepackage{tikz}
\usepackage[papersize={51pt,51pt},margin=.5pt,centering]{geometry}
\begin{document}
\parindent 0pt
\begin{tikzpicture}
 \draw[line width=.5pt] (0,0) circle (24.75pt);
  \draw (0,0) node{24.75pt};
\end{tikzpicture}
\end{document}

It results in pdf file which looks perfect in AR, evince, kpdf, Apple
"Get Info" but not in Apple Preview and other applications using the
same engine: it looks like pdf was slightly cropped from the top and a
tiny margin was added on the bottom. Further, running pdfcrop
generates pdf which looks perfect in Apple Preview and Co as well


Would be it possible to explain the reason of such unusual behavior?

Victor
