Detecting animated state in a macro?

[Bill Mohler]

  Is there any way to detect whether a stack is currently animated using
macro code?

Hi Bill,

You can try the following code. You might have to adjust the wait time, depending on the your stack size and speed.

------------------------------------
a = getSliceNumber();
wait(1000);
b = getSliceNumber();

if(a!=b)
print("Stack is animated.");
else
print("Stack is not animated.");
-------------------------------------

Bill, Ved,

The following macro retrieves the animation state of the current stack using
a javascript call. The state is returned using the built-in preferences
mechanism, because the eval() macro function cannot return a value.

s="Prefs.set('is.animated',WindowManager."+
"getCurrentImage().getWindow()."+
"getAnimate());";
eval("script",s)
a = call ('ij.Prefs.get','is.animated',false);
print ("animated: "+a);

Thanks for your advice. I guess I'll have to experiment to find out how
much lag there might be in the disk-access required (I think) for the
prefs approach, versus the need to wait for a frame change in the
getSliceNumber approach. I'm trying to set up a very quick response in
the UI to a keystroke, but need to know whether the stack is currently
animated before choosing which actions to perform. It would be best, I
think, if a macro command could directly return the current value of
StackWindow.getAnimate().  Obviously this means work for Wayne, but I
think it would be useful.

Thanks to all,
Bill

The is("animated") macro function, added in the 1.44g daily build, can be used to detect if a stack is currently animated.
