I am currently drawing some charts and diagrams using MS Visio. But when I convert them into pdf for using in Latex-Documents, I get the whole page of the vsd-file, and not just the diagrams etc. So the entire page will be converted into pdf. Since I don't have access to tools such as Adobe Acrobat Pro etc., I also can't cut the diagram from the pdf-file just so. Adobe Reader hasn't got any alike function except the snapshot, which only helps if I copy it into MS Word or so. I am not an expert of MS Office, so I also can't convert to the pdf from MS Word, without having page background.
So the question is, is it possible to only convert the diagrams/charts or selections into pdf in -preferably- Visio or Word?
Thanks!
