[pstricks] pst-eps: \color{white} vs. \fbox[linewidth=0pt]{...

[hjsalchow at aol.com]

In his book Voss (2005)  explained how to create an encapsulated
postscript file from a PSTricks-graphics file. He suggests (see page
245, listing 21.1)

...
\begin{document}
\color{white}
\fboxsep=0pt
\fbox{<some PSTricks-graphics commands>}
\end{document}

There may be a minor inelegancy in this procedure. If you follow this
proceture you may wonder where all the prosa is gone you added in your
PSTricks-graphics commands. The answer is simple: its color was changed
to white, too.

Recall that the \color{white} was set, just to make the frame of \fbox
invisible. A more adequate solution for this simple problem may be to
set the linewidth of the \fbox to zero. For example

\fboxsep=0pt
\fbox[linewidth=0pt]{<your PSTricks-graphics commands>}
