Get the 'changes' flag of an image in a macro

[Tiago Ferreira]

Sorry if this will sound silly:

I am trying to detect in a macro if changes have been done to an image.

Using built-in macro functions I know I can use ' setOption("Changes",boolean)'
to SET the 'changes' status of an image, but I don't know how to GET it...

I guess I would need to read the value of  'changes' in class ij.ImagePlus...

Does anyone have an idea on how to obtain this in a macro?

The latest 1.42m daily build has a is("changes") macro function that  
can be used obtain the value of the 'changes' flag.
