Hi all,

Suppose I have enclosed an area using the polygon selection tool and got
ImageJ help me measure the enclosed area with its Measure function. I
wish to know how does ImageJ do it i.e. by trapezoidal rule or something
else? Also if possible, can someone point to me the folder in which the
code lies?

Regards,
Justin
