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.
