[Tex/LaTex] the cause of the error “Package keyval Error: orientation undefined”

errorsgraphics

When I try to compile the following code on Windows using MikTeX and TexWorks,

I get the error "Package keyval Error: orientation undefined".

I understand that it is referring to line 69, which has a \end{frame}. What I do not know is why is this LaTeX code not compiling on Texworks on Windows XP? It works on Kile on an Ubuntu box.

Best Answer

orientation is an undefined key for \includegraphics. Maybe you're interested in some form of rotation, which you can specify using the angle key-value.

Why did it compile on a different system? Perhaps it passed through the error due to switch -interaction=nonstopmode.
