Hello,
I suppose the control Adjuster does nothing because it doesn't work with
your frame.
The ContrastAdjuster is running on the current displayed image found by
the WindowManager method:
ImagePlus imp = WindowManager.getCurrentImage();

It is probably why in your code,  the B&C don't know your ImagePlus object.
If you want to use the ij B&C, you can modify it in order to apply it on
your own image...

Rémi.
