Hi all ! I'm new here, so i'l try to be as clear as possible !

I'm using the FreehandRoi object in my project. I would like to know if it's
possible to measure the integrated density of a FreehandRoi object ?

I'm doing it well for rectangular Roi's (with the good results) via :
    [...]
    Analyzer.setMeasurements(Measurements.INTEGRATED_DENSITY);
    resultTable = myRoiManager.multiMeasure(MyImagePlus);
    resultTable.show("test");
    [...]

When i tried to do this with an FreehandRoi object, it doesn't work. I only
receive NaN for both (Inden and RawInDen) for all my frames in my ImagePlus.

Does someone have an idea ?

PS : the debug properties of myFreehand object is :
            bounds : null
            x,y,w,h: 57,32,1,1  
       as example, but i don't know if the two 1 and the null bounds are
normal


Thanks in advance !! Have a nice day.

Best regards,

Louis
