Awesome! I'll be sure and check that out. I tried version 1.7 (command line) for my prs500 last night, but it didn't seem to work properly. It made the .png's but then the .lrf was empty. Interestingly, 1.6 worked fine.
I'll give 1.8 a whirl and see if the mac issues with 1.7 have been fixed.
Is 1.8 a fork? Why does the sourceforge page still only have up to 1.7?
Great software btw.... it's the best workaround for viewing non-optimal pdfs that I've found. Keep up the good work!
