It's true :) I'd like to make screencasts (gifs) by saving a picture of an
Emacs window or frame after each redisplay (I tried a number of programs that
record screencasts, but they all gave disappointing results; by saving a
picture (and a timestamp) after each redisplay, I might get much better
results).
A post-command hook would almost work, but it doesn't work for, say, a
compilation buffer showing new output.
Would it be hard to add a redisplay hook? Alternatively, is there a
non-deprecated way to achieve what the snippet that I posted does?
Also, is there a way to save a bitmap copy of a frame, other than asking the
system to take a screenshot? Could emacs do a redisplay cycle but write to a
bitmap instead of the screen?
Cheers,
Clément.
