Question: tickmarks

A scientific journal, which will remain nameless, requires that tickmarks on the plots face IN rather than OUT. I don't see how to change this in Maple... I can't blame them, it seems like a triviality. So is there a way? And failing that, anyone have any ideas. I'm thinking I'll load the gifs into gimp and fix them that way, but that seems awfully roundabout. Thanks.
