You've created a wonderful written report as a {\tt pdf} or {\tt ps}
file. Or you've created a beautiful figure as a {\tt pdf} or {\tt ps}
file. Or you have a {\tt jpg} image from your camera. How do you display
and/or print these in Linux?

The most common display programs are in the following table. Our
favorites are {\tt evince} for documents and {\tt xv} for images.

\begin{verbatim}
 pgm   img.ps img.eps img.pdf img.jpg  doc.pdf doc.ps  to     comments
                                 etc                  quit   

evince    y      n       y       n        y       y  ctrl-w   no GUI menu
xv        y      y       y       y        y       y    q      pixels; some image editing 
gv        y      y       y       n        y       y    q      gs + gui
display   y      n       n       y        n       n    q      good image editing
xpdf      n      n       y       n        y       n    q
gs        y      y       y       n        y       y    q      bare bones
\end{verbatim}

\noindent Comments: \begin{enumerate}
\item {\tt evince} is the most capable for documents. The only problem
  is a temporary glitch: the GUI menu is unavailable. So you
  need to memorize a few basic keybindings, taken from {\tt
    evince\_keybindings.pdf} The most important is to {\it print} use {\tt
    Ctrl p}.

\item {\tt xv} will handle almost any kind of file, especially image
  files. It has some image editing and file conversion; for a GUI,
  right-click. {\tt xv} is not available on all Linus/UNIX
  installations. Disadvantage: {\tt xv} pixellates the file before
  displaying it, so you can't enlarge the image while retaining detail.

\item {\tt gv} works on {\tt ps} and {\tt pdf} files only. It's a little
  less nice than {\tt evince}, but it has a nice GUI and is surely
  available on any Linux/UNIX platform.

\item {\tt display} is meant for images. It has a GUI for lots of image
  editing options. It's the modern replacement for {\tt xv}.

\item {\tt xpdf} is a basic, no-frills {\tt evince}---but at least it has GUI,
although it's somewhat primitive, 

\end{enumerate}
