Saving Visio files as EPS to put in LaTeX:
From Visio do File-> Print. Chose the best printer available.
choose print to file. Say the file is "foo.ps"
in a multi-page document, choose print range = "current page"
click on "properties" of the printer, then click advanced
under "graphic" change "print quality" to the highest dpi you can
under "Document Options->Postscript Options" set "Postscript Output Option" to "Encapsulated PostScript" Click "ok" until it prints. On the current document, it'll complain that the page size is wrong. Ignore that.
At this point you have a ps file. Yes, I know, we said to save as EPS, but it gets the bounding box and some other details wrong.
Open foo.ps in Ghostview. Important: this must be a fairly recent version of ghostview; the one on the cs.ubc.ca linux machines is not recent enough.
Choose File->PS to EPS.
Make sure that "automatically calculate bounding box" is selected.
Say you've read the help (trust me, it's only relevant if it goes wrong).
click "yes" and save as a file.
Voila! You have an EPS file that should work with LaTeX and appear (approximately) correctly in ghostview.
Caveat: Irritatingly, the "right" way to do this seems to change pretty often, so you may someday discover that it needs to be re-adjusted.
