+\section{Introduction}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+Frida is a versatile data-analysis program.
+From a command-line interface, it offers various methods to
+visualize, manipulate and fit tabular data.
+Frida is especially designed for the analysis of spectral data,
+in particular from quasielastic neutron scattering (QENS).
+
+Frida is currently in maintenance mode, which means:
+bugs will be fixed speedily,
+new features will be implemented occasionally,
+but development at large is stalled until a decision is taken
+which QENS software shall be institutionally supported at MLZ and
+partner institutes.
+
+The following notes describe how to post-process PostScript graphics files
+generated by Frida, in order to obtain publication-grade figure.
+These notes have grown out of an oral tutorial.
+They will be gradually converted from slide-show format to written-manual style.
+
+In Frida, two different methods are used to visualize data.
+For screen display in interactive sessions,
+Frida spawns a Gnuplot session.
+Plot commands are sent from Frida to Gnuplot through a first-in, first-out pipe.
+For saving graphics (command \texttt{gp}),
+Frida does \E{not} use Gnuplot's PostScript backend,
+but directly writes PostScript commands to a file.
+In the following,
+the structure of this Frida-generated PostScript file is explained,
+and it is shown how to embellish a plot by a few edits to this file.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\section{Graphic formats, workflow}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+\subsection{Graphic formats}
+
+Graphics can be stored in many different file formats.
+\Cref{Tgformats} lists formats that are in wide-spread use.
+One distinction is between \E{proprietary} and \E{open} standards.
+It strongly correlates with the distinction between \E{platform-specific}
+and \E{cross-platform} formats.
+To facilitate cooperation,
+we should prefer open, cross-platform standards whenever possible.
+Platform-specific formats like Windows Metafile (wmf)
+or Enhanced Metafile (emf) should be avoided.
+
+The most important distinction, however, is between \E{raster graphics}
+(bitmaps, pixel maps) and \E{vector graphics}.
+In raster graphics, the coloring of each single pixel in an image
+is specified.
+Typically, for each of the three base colors,
+values between 0 and 255 can be specified.
+Additional, there may be a fourth number to indicate transparency.
+So there are three or four bytes per pixel.
+Accordingly,
+an image with $1000\times1000$ pixels (1~Megapixel) is stored in a file
+of size 3~or 4~MByte.
+
+In contrast, a graphics file in vector format specifies an image in
+terms of basic plotting operations.
+Such operations include: choice of color, pen, font;
+coordinate system transformations;
+specification of path, clippath, region;
+drawing lines, arcs, Bezier curves using chosen pen;
+printing text using characters from chosen font.
+In this way, complex plots can be stored in a file
+that takes only a few kBytes.
+
+\begin{table}
+ \begin{center}
+ \btabb @{}p{.32\TW}@{}p{.42\TW}@{} 1.1
+ \hline

+ svg &vector, XML-based, for WWW\\
+ pbm, pgm, ppm, pnm & bitmap (b/w, grey, color, any)\\

+ \hline
+ \etabb
+ \end{center}
+\caption{Frequently used data formats}
+\label{Tgformats}
+\end{table}
+
+Advantages of vector format over bitmap:
+ \bitem
+ \I scaling without quality loss
+ \I easier manipulation
+ \I smaller files
+ \eitem
+ \bigskip
+ Therefore:
+ \bitem
+ \I don't convert to bitmap until unavoidable
+ \I usually, leave conversion to
+ \bitem \I printer / printer driver
+ \I screen viewer (\texttt{acrobat}, \texttt{evince}, \ldots) \eitem
+ \I since 2013, even MS Words understands PDF
+ \eitem
+
+\subsection{Figures in LaTeX}
+
+ [from memory, needs verification]
+
+ classic LaTeX:\\
+ \bitem \I generates PS \I includes only PS\eitem
+ \bigskip
+ pdfLaTeX:\\
+ \bitem \I generates PDF \I includes PDF and many others, but no PS\eitem
+ \bigskip
+ XeLaTeX:\\
+ \bitem \I generates PDF \I includes all current graphic formats\eitem
+
+\subsection{Workflow for Frida figures}
+ \bitem
+ \I plot commands \texttt{p}, \texttt{a}
+ \I \texttt{gp} creates e.~g.\ \url{~/gnew/l97.ps}
+ \I rename file, move to appropriate folder
+ \I open with viewer (e.~g.\ \texttt{evince})
+ \I in parallel, open with editor and modify
+ \I \texttt{bboxx -insert <filename>.ps}
+ \I \texttt{ps2pdf -dEPSCrop <filename>.ps <filename>.pdf}
+ \eitem
+

+\section{Postscript}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+\subsection{PostScript}\label{STEST}
+ Basic facts:
+ \bitem
+ \I Created around 1981, few additions
+ \I Open standard: Red Book
+ \I Lossless convertible $\leftrightarrow$ PDF, SVG
+ \I Programmable in plain ASCII
+ \eitem
+ \bigskip
+ To come:
+ \bitem
+ \I 4 slides on programming
+ \I 2 slides on plotting
+ \I then back to Frida
+ \eitem
+
+
+\subsection{Programming PostScript}
+ Compute $(780-120)/2$:
+ \bigskip
+\lstset{basicstyle=\ttfamily\normalsize}
+\begin{lstlisting}
+ 780 120 sub 2 div
+\end{lstlisting}
+
+
+\subsection{Programming PostScript}
+ Convert $r=7$, $\varphi=36^\circ$ to Cartesian coordinates
+\lstset{basicstyle=\ttfamily\normalsize}
+\begin{lstlisting}
+ 7 36 % -> 7 36
+ 2 copy % -> 7 36 7 36
+ cos % -> 7 36 7 cos(36)
+ mul % -> 7 36 x [where x=7*cos(36)]
+ 3 1 roll % -> x 7 36
+ sin % -> x 7 sin(36)
+ mul % -> x y [where y=7*sin(36)]
+\end{lstlisting}
+
+
+\subsection{Programming PostScript}
+ Convert $r=7$, $\varphi=36^\circ$ to Cartesian coordinates
+\lstset{basicstyle=\ttfamily\normalsize}
+\begin{lstlisting}
+ 7 36
+ /phi exch def
+ /r exch def
+ r phi cos mul % -> x
+ r phi sin mul % -> x y
+\end{lstlisting}
+\bigskip
+Easier and clearer, but does not allow iteration\\
+(only global namespace)
+
+
+\subsection{Programming PostScript}
+ Subroutine to convert $r$, $\varphi$ to Cartesian coordinates
+\lstset{basicstyle=\ttfamily\normalsize}
+\begin{lstlisting}
+ /polar2xy { % r phi | x y
+ 2 copy % -> r phi r phi
+ cos mul % -> r phi x
+ 3 1 roll % -> x r phi
+ sin mul % -> x y
+ } def
+\end{lstlisting}
+\bigskip
+Application:
+\begin{lstlisting}
+ 7 36 polar2xy % yields 7*cos(36) 7*sin(36)
+\end{lstlisting}
+
+
+\subsection{Programming PostScript}
+\subsubsection*{Exercises}
+This code fragment takes one operand. What does it return?
+\lstset{basicstyle=\ttfamily\normalsize}
