The image is in landscape format when viewed with gv.

Short answer: use `width' instead of `height':


Long answer:

,----[ http://www.tex.ac.uk/cgi-bin/texfaq2html?label=divzero ]
| Graphics division by zero
| While the error
| ! Package graphics Error: Division by 0.
| can actually be caused by offering the package a figure which
| claims to have a zero dimension, it's more commonly caused by
| rotation.
| Objects in TeX may have both height (the height above the
| baseline) and depth (the distance the object goes below the
| baseline). If you rotate an object by 180 degrees, you convert
| its height into depth, and vice versa; if the object started
| with zero depth, you've converted it to a zero-height object.
| Suppose you're including your graphic with a command like:
| \includegraphics[angle=180,height=5cm]{myfig.eps}
| In the case that myfig.eps has no depth to start with, the
| scaling calculations will produce the division-by-zero error.
| Fortunately, the graphicx package has a keyword totalheight,
| which allows you to specify the size of the image relative to
| the sum of the object's height and depth, so
| \includegraphics[angle=180,totalheight=5cm]{myfig.eps}
| will resolve the error, and will behave as you might hope.
| If you're using the simpler graphics package, use the * form of
| the \resizebox command to specify the use of totalheight:
| \resizebox*{!}{5cm}{%
|   \rotatebox{180}{%
|     \includegraphics{myfig.eps}%
|   }%
| }


Computer games don't affect kids. If Pacman would have affected us as
children, we would now run around in darkened rooms, munching pills
and listening to repetetive music.
