Solution: Undim screen before taking screenshot
Authored by: mithras on Mar 09, '03 03:16:40PM

As others noted above, the problem that some encounter is that screen bitmaps can't be captured when the monitor is dimmed.

The solution is to undim the monitor briefly, before taking the screenshot.

I wrote a tiny program called undim that makes the one-line call to IOKit to undim the screen. It uses a snippet from the OSXvnc server.

You can download undim from me at http://mithras.homeunix.net/downloads
