My never ending battle with plot drivers... (tiff.plt)

Hi!

I was wondering if anyone knows how to change the dpi in the tiff.plt file? The resolution line under the sizes says " resolution(IN)=(0.01,0.01) ; 100 dpi". I need it to be atleast 300. What would the resolution be? And more importantly, does that really control the dpi?

I would appreciate any help!
