Dear all,
I am trying to obtain the grey values from a region of an image using the
Rectangle tool. When I use only the Straight Line and then Anaylze > Plot
Profile, I obtain a graphic with the gray values and distance (X,Y). But
when I want to analyze an area using the rectangle tool and then Analyze >
Plot Profil, I obtain a graphic with the average of gray values in each
distance.
Do you know how can I do to obtain the gray value in every point of the
square and not only the average?
