Hi,
my last message was inexact. You need to send getGlobalCalibration() to
an ImagePlus object, not to the class.
The best thing to do might be to get the image and use the method
getCalibration(). If a global calibration exists the method answers the
global calibration otherwise it answers the local calibration of the image.
