Yes, I imported a tif file, exported it in eps and reimported it back ok. The eps exported from Mathematica was level 2. ted Chris Chiasson wrote: >So the EPS level 2 files do Import and display (using Show) in >Mathematica then? > >On 5/3/05, Ted Sariyski <tsariysk at craft-tech.com> wrote: > > >>ps was my first try but I get "Invalid file format".

When I try to import them I got "Invalid file format". That's why I converted the files to a format I was able to import. Actually that's one of my questions: Why I'm able to import eps level 2 but unable to import eps level 3 into Mathematica? >>>>Thanks, Ted >>>> >>>> >>>>Chris Chiasson wrote: >>>> >>>> >>>> >>>> >>>> >>>>>Why import a tif into Mathematica and then export it as an eps?
