More About the Line Profile

Overview

The line profile feature, available by clicking in the Output pane, draws a line on the top of the displayed image, and shows the corresponding line profile plot at the bottom of the pane.

The line profile plot shows the light intensity values (monochrome image) or color intensity values (color image) on the various points along the line segment (line profile) drawn on the image.

Examples
