OK, yeah, this operation will probably be slow! Taking a screenshot is a
time consuming op. I don't think there's much to do about that. I mean,
just run the Applications/Accessories/Take Screenshot app to see how
long it takes.

There is probably a better way to implement your app. What exactly do
you want to do?
