[CentOS] ooimpress in show only mode

hi all.

Look at ooimpress on centos 5 x86_64.

been trying to find a way to get it to just show a power point and not 
show the editor screen.

tried:

ooimpress -show pp.ppt
ooimpress -invisible -show pp.ppt
ooimpress -headless -show pp.ppt
and others
I always get the editor window.

Did some google searching and didnt find anything...

Was wondering if anyone knows how to start impress and not show the editor.
I just want to see the power point in slide show mode.

Thanks,

Jerry
