Hi!
I'd like to get a screenshot (PNG) of an agenda of mine by following
snippet:
(defun my-export-month-agenda-to-png-via-screenshot()
(interactive)
(org-agenda nil "n") ; generates agenda "n" (one month without todos)
(if (my-buffer-exists "*Org Agenda*")
(switch-to-buffer "*Org Agenda*")
(org-agenda-list)
)
(message "Waiting for Screenshot ...")
(sleep-for 1)
(message "Say cheese ...")
(setq myoutput
(shell-command-to-string "/usr/bin/import -window root /home/vk/share/agenda.png"))
(message (concat "Screenshot done (" myoutput ")"))
)
The code works somewhat: the corresponding agenda is generated, a
screenshot (via imagemagick) is created. But: on the screenshot, I
see the buffer from where I invoked
my-export-month-agenda-to-png-via-screenshot in the first place and
in the minibuffer I can read "Say cheese ...".
Therefore it seems to be the case that basically the function
changes to the newly created Agenda buffer *after* the screenshot
and probably after the end of the function.
As you can see, I tried to change to the agenda buffer «manually»
via switch-to-buffer with no change of the result. I even tried to
get the result I am wishing for by adding a one-second sleep phase
which should cancel out any buffer-switch-performance-delay.
Can you help me, what is going on here?

Hi Karl,
This seems strange to me too. I tested your code and found that the
screenshot always showed the pre-agenda state of the frame, showing the lisp
window at the top and the helm-M-x window at the bottom, the way it looked
when I hit RET to run the command.
However, I tried stepping through the function with edebug, and then it
worked properly: the screenshot was taken after the agenda displayed, and it
showed the agenda in the screenshot.
I don't know much about Emacs internals, but I'm guessing that something's
preventing the frame from being repainted until the function finishes.
Maybe you could use a separate function to take the screenshot and call it
with a timer?

You seem to have found the root cause. What works at my side:
(defun my-export-month-agenda-to-png-via-screenshot()
(interactive)
(org-agenda nil "n") ; generates agenda "n" (one month without todos)
(if (my-buffer-exists "*Org Agenda*")
(switch-to-buffer "*Org Agenda*")
(org-agenda-list)
)
(message "Waiting for Screenshot ...")
(sit-for 1)
(message "Say cheese ...")
(setq myoutput
(shell-command-to-string "/usr/bin/import -window root /home/vk/agenda.png"))
(message (concat "Screenshot done (" myoutput ")"))
)
