It's true the ContrastAdjuster is running on the current displayed image
found by the WindowManager method.

And I think that the ImagePlus I define in my frame corresponds to the
value returned by WindowManager.getCurrentImage() because the histogram
plotted in the B&C window corresponds to the "image.bmp" image ...

Is it possible to add some methods like "update()" rather than modifying
the ImageJ plugin ??
