 Firstly, EPS is a vector format so DPI doesn't make any sense (except
for embedding raster image data within it).

 Secondly, how do you know many dots (pixels) to make your image if
you don't know how big in inches your image is going to be?

 Thirdly, if its a graph, it's probably best saved as an EPS to
preserve the inherent vector nature of a plot.

 Fourthly, I should have answered this on stackoverflow.org in order
to increase my reputation points :) Or maybe decrease them :)
