Re: [9fans] How to take a portion of a screenshot

Thanks Skip, Cinap,

This command seems to be working quite nicely (except for the memory allocation problem in gif(1) for larger recordings):

for (i in `{seq -w 1 25}) { sleep 0.01; cat /dev/screen > /tmp/screen-$i.img }; togif -l -1 -d 300 /tmp/screen-*.img > /tmp/recording.gif; rm /tmp/screen-*.img; echo Done

It would be easy enough to introduce a crop to restrict the recording to a particular window or area of the screen.

Is there a way to capture the current mouse position without blocking to wait on an event from /dev/mouse? I was thinking that it would be interesting to crop around the current mouse position.
