Hi Cspr,
Where cal is a declared Calibration object and imp the ImagePlus object of
interest use:
cal = imp.getCalibration();
x = cal.pixelWidth; //x contains the pixel width in units
y = cal.pixelHeight; //y contains the pixel height in units
z = cal.pixelDepth; //z contains the pixel (voxel) depth in units
if you need the name of the unit (e.g. micron) then ij.measure.getUnit()
returns the singular form as a string and ij.measure.getUnits() the plural.
Hope this helps,
Julian
