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. To change the line ("marker") this command draws on the image, see Marker Preferences.

Choosing the Appropriate Plotting Command

A line profile can be plotted using either the present command or by using the direction-specific commands for a Column Profile or a Row Profile. There are some unique capabilities offered by each method.

The Line Profile Plot

The Line Profile is drawn into a Plot Window like that shown below. Notice that the horizontal axis is distance, not an absolute position as for Column and Row Profile Plots.
