Is there any way through either the HTTP or Telnet Property interfaces
to force a screenshot to be taken?
That's easy. On a very recent CVS (= development) version write this into
a file $FG_ROOT/Nasal/local.nas:
INIT = func {
setlistener("/sim/screenshot", func { fgcommand("screen-capture",
props.Node.new()) });
}
settimer(INIT, 0);
Then set property "/sim/screenshot" via telnet to an arbitrary value.
On older systems you write this into that file and set /sim/screenshot
to a positive value:
screenshot = nil;
loop = func {
if (screenshot.getBoolValue()) {
fgcommand("screen-capture", props.Node.new());
screenshot.setBoolValue(0);
}
settimer(loop, 0.05);
}
INIT = func {
screenshot = props.globals.getNode("/sim/screenshot", 1);
screenshot.setBoolValue(0);
loop();
}
settimer(INIT, 0);
If screen-capture is the exposed function name, then you should also be
able to just setup the telnet interface, telnet in, and type "run
screen-capture".
