If the screenshot includes lots of fancy menu's and icons and other graphical formatting, it might be more bitmap oriented i'd argue.
I didn't mean that, I agree. What I pointed out is that screenshots are vector-like because of the numerous straight lines, rectangles, characters, etc. but are bitmap by way of capture procedure. Any software able to reconstruct the vectors from the bitmap (would look like a graphical OCR) ? >> >>Anyway, it is safe to conclude there are many ways of converting (or even obtaining) screenshots and the best way depends on your application. That's not true: the best way is to keep it of good quality in the printed documents, whatever the application. If you don't understand (and I truly not claim here to have understood all the odds and ends of image conversion) the basics of image manipulation, resolution and conversion, you will get into trouble. These are not application dependent, they are truly depending on the current state of the art of image format. To be (very) short: - drawings with characters: goto to EPS, convert from there - screenshots: goto PNG if no native EPS available (may happen with good quality applications), avoid conversion to EPS unless you're aware of the pitfalls - pictures: goto JPEG, EPS conversion bearable due to natural texture anti-aliasing, resolution depnds on the original compression factor (this is true for PNG as well, AFAIU). You want to know more ? understand the various options of Imagemagick convert/mogrify (may take some time). >> >>A question to conclude this mail: what is the difference between the two options one >gets when insert->figure'ing ?
