BTW, the output would presumably be better as png files, but I don't really know if I can count on my students' web browsers being able to read this format. Anyone who knows what browsers *can't* handle png files?
You may be able to find this information on the png home page at http://www.libpng.org/pub/png/ . Seems to be unreachable right now (for me, that is).
It was unreachable for me too.
Lots of mirrors are available, though, and they say Netscape and IE got support in late 1997 except for transparency, which our driver does not produce. E.g. http://www.mirror.ac.uk/sites/ftp.libpng.org/pub/png/pngstatus.html
To my little experience, "new" browsers will display png files all right
("new" meaning something >= Netscape 4.7 or Explorer 5). Older versions may
display them partly (without transparency effects, for instance). Or not at
all. :-(
<rant> Yes. Unfortunately, PNG is yet another example of good technologies being (or have been) ignored by browser makers because browser makers are more concerned with winning a browser war than providing useful software. </rant> I would suggest installing the ImageMagick "display" utility on all systems. <URL:http://www.simplesystems.org/ImageMagick/www/display.html>. It can display images on all systems running X server. Also, ImageMagick itself <URL:http://www.simplesystems.org/ImageMagick/> runs on most popular OSes, including Mac and Win32 (and obviously, unices), so you may get something out of that that can be used to view graphs on most platforms.
Um. It's an awful lot of effort to do that on Windows, and the only stable X servers I know there cost real money. Just to confirm, ImageMagick on Windows requires an X server, and in my experience a good one at that. GIMP will also work on most platforms, natively on Win32.
