            Bug ID: 1148
           Summary: Different mean intensity than in analyze, measurements
           Product: Fiji
           Version: unspecified
          Hardware: Macintosh
                OS: Mac OS
            Status: NEW
          Severity: normal
          Priority: P4

When I try to run the following code in Javascript:

importClass(Packages.ij.IJ);
importClass(Packages.ij.plugin.frame.RoiManager);
importClass(Packages.ij.io.OpenDialog);
importClass(Packages.ij.io.DirectoryChooser);
importClass(Packages.java.io.File);
importClass(Packages.ij.gui.GenericDialog);
importClass(Packages.ij.util.Tools);
importClass(Packages.ij.plugin.Duplicator);
importClass(Packages.ij.measure.ResultsTable);
importClass(Packages.ij.ImagePlus);
importClass(Packages.ij.process.ImageProcessor);

IJ = IJ();
rm = RoiManager.getInstance();
rt = ResultsTable.getResultsTable();
if (rm==null) rm = new RoiManager();
if (rt==null) rt = new ResultsTable();
//var procName = "MC21_w1cf-Brightfield_s1-0001proc.tif";
//IJ.selectWindow(procName);
impProc = IJ.getImage();
rm.select(impProc, 0);
ipProc = impProc.getProcessor();
stats = ipProc.getStatistics();
mean = stats.mean;
print("The mean is: " + mean);

stats2 = impProc.getStatistics();
mean2 = stats.mean;
print("Mean2 is: " + mean2);

I get the following output:

The mean is: 14891.73076923077
Mean2 is: 14891.73076923077

However, if I go to the graphical user interface and do analyze, measure, I get
a different answer:

18444.4111
