Line Profile


A Line Profile is a graph of pixel values versus distance along a line drawn on the image. A Line Profile differs from a Column Profile Plot and a Row Profile Plot in that the sample line is drawn manually using the mouse, In addition, the Line Profile plots luminance versus distance on the x-axis, whereas a column or row profile plots luminance versus position.
