\label{sec:konfigurationseintraege}
Configuration entries can be specified using different ways. To create
A4 output for a grayscaled laser printer you can use one of the
following commands:
\begin{lstlisting}
bmeps -l ps2 -o color=no -o media.size=A4 ...
bmeps -l ps2 -o c=n -o m.s=A4
bmeps -l ps2,color=no,media.size=A4 ...
bmeps -l ps2,c=n,m.s=A4 ...
\end{lstlisting}
Alternatively you can create a configuration file
\begin{lstlisting}
[printer:ps2]
color		=	no
media size	=	A4
\end{lstlisting}
and use the ``-l'' option to choose the configuration:
\begin{lstlisting}
bmeps -l printer ...
\end{lstlisting}

I recommend to use the full configuration entry name in the
configuration file. Abbreviations should be used on the command line only.

The following configuration entries can be used:
\begin{itemize}
\item	\texttt{output type} = \textit{string}\\
\texttt{o.t}\\
Output type, either ``ps'', ``pdf'' or ``bb'' (bounding box file
for \LaTeX{}).\\

\end{tabular}
\item	\texttt{level} = \textit{string}\\

or ``1.2'', ``1.3'' or ``1.4'' for \textsc{pdf}.\\

\item	\texttt{page}\\
shows page completely in window.
\end{itemize}

\item	\texttt{jpeg interpolate} = \textit{boolean}\\
\texttt{j.i}\\
works in conjunction with ``interpolate'' and
enables/disables image interpolation when passing through
\textsc{dct} encoded data from a \textsc{jpeg} file.
If this option is disabled, interpolation is turned of for
\textsc{dct} passthrough.\\

are separated by a colon, abbreviations can be used, i.e.
``a:r:f:d'' for ``ascii85:run-length:flate:dct''.\\
\figimage{compression}{Compression and encoding algorithms}%
The order of appearance in the list is insignificant, see
figure~\vref{fig:compression} for possible sequences of encodings.
The following encodings/compressions can be used:
\begin{itemize}
\item	\texttt{ascii85}\\
\texttt{a}\\
ASCII85-Encoding. If deactivated, ASCII-Hex-Encoding is used.
\item	\texttt{run-length}\\
\texttt{r}\\
Run-length compression.
\item	\texttt{flate}\\
\texttt{f}\\
Flate compression.
\item	\texttt{dct}\\
\texttt{d}\\

Bmeps does not \textsc{dct} compress data, but it can pass through
\textsc{dct} compressed data from \textsc{jpeg} files.
\end{itemize}

\texttt{j.s.s}\\
PostScript level 2 only allows \({\text{SOF}}_0\) and
\({\text{SOF}}_1\) markers in \textsc{dct} compressed data.\\
Some printers and interpreters implement support for additional
markers. To specifiy the set of marker, create a colon-separated list
of number, i.e. ``0:1:2'' to allow \({\text{SOF}}_0\), \({\text{SOF}}_1\)
and \({\text{SOF}}_2\).\\
