As I said earlier, I'm working on the tutorial in the LM. It uses
screenshots to show what users will see on the screen. The versions on the
web are (as expected from a pixel-based system) fine. However, the versions
in the PDF docs are badly scaled and look ugly. It seems that this is
generally tackled for images by making them large and then constraining the
width in the tex version of the source (this is how it's done in the essay).
I'm wondering if there's a better way - is there a recommended
pixel-per-inch setting for image files that will end up in the PDFs? I've
looked on the web and couldn't find anything, but am hoping someone will
know.
