Hi Michael, Sorry if my text wasn't clear enough and I confirm that "command does update the histogram display" (as I wrote "As the min and max levels seem to be updated"). The issue is that the method name doesn't get updated within the "Threshold..." window. Thus a user can't know "which" or "if" a given method had been set by the macro code. Kindest regards, Philippe

You won't see much difference with the Blobs sample and these thresholding methods because they all yield essentially the same threshold. If you use a different image like the M51 galaxy sample, you can better see it.
