\section{Graphics on Athena}

\subsection{Quick Work}

There will be times when you will need to make a 
quick image file for some purpose: to make a poster, 
decorate a web page, make a graphic for a course related
paper, or other purposes. There are several tools on 
Athena that will help you do that. Most reside in 
the {\em graphics} locker. If a tool is mentioned 
and its locker is not named, presume that it lives in 
the {\em graphics}.

For a quick and dirty drawing, you have your choice of 
{\tt xpaint}, {\tt gimp},
as well as the Applix and Open Office suites, both 
of which have drawing components. All these are available
from your Athena menu bar. 
For a more schematic drawing, you can use 
{\tt xfig}, {\tt tgif}, in the {\tt sipb} locker, 
{\tt dia}, in its own {\tt dia} locker,   
or {\tt xcircuit} in the {\tt xcircuit} locker.  

To edit an image file for cropping, resizing, 
color corrections, or other quick tasks, 
there is the {\tt xv} utility in the {\tt graphics}
locker. Just type {\tt add graphics; xv filename} and
when the window showing the image pops up, right-click
on it to see what xv can do for you. 

To grab a screenshot in the Athena GNOME environment, 
jsut press the PrintScreen button. A dialog will show up
to let you save your screen in the PNG format. 
You can also use the utilities {\tt xdpr}, and  {\tt xv}
for the same purpose, as well as the GIMP. 

To make file conversions at the command line there is
a whole slew of utilities in the {\tt graphics} locker. 
If the {\tt convert} utility (on the Suns it is known 
as  {\tt imconvert}) can't do it for you, then just type
the suffix of your input graphics file name (for 
example, {\tt athena\% png}) and then the tab key, 
and a whole list of utilities should pop up. 
For more information, type {\tt add graphics; man convert}
and {\tt man mogrify}. 

To make animated image files, the {\tt graphics} locker
containes two very useful utilities, 
{\tt gifsicle} and {\tt animate}. Both have manual pages
with instructions for using them. 

\subsection{The GIMP}

The GIMP is your Serious image editing tool on Athena. 
It slices. It dices.
Just type {\tt gimp \&} and have at it. 
Tutorials and guides for using it are found at 
{\tt http://www.gimp.org}.
