profile of a line

[Ben Liu-3]

Hi there,

if the line width is larger than one, say 5, does the "Plot Profile" function return the profile along the center of the line or the averages of 5 pixels along the line?

Thanks.
Ben

With straight line selections, it returns the averages of the pixels
along the line.
