Line Profile

A line profile is a representation of the pixel intensity values along a line that you draw in the image.  The line can be straight, in the shape of a circle or square, a polyline, or a polygon.  The line profile of the line lists and graphs the brightness/darkness value of each pixel along that line.  The brightness/darkness values are expressed as either pixel intensity values or, if a calibration definition has been applied to the image, as calibrated values.  

When you click the Line Profile tool, the Line Profile ribbon is displayed at the top of the Image-Pro application window, and the Line Profile Window is displayed at the bottom of the application window.

Line profile data can then be obtained and analyzed using the tools on the Line Profile tab's ribbon.  Use the links below to access related help topics.

Note: The line profile tool measures pixel values as they exist in the image bitmap.  It does not reflect values as they are interpreted through the LUT.  This allows you to make visual adjustments to your image for viewing purposes without affecting the data used for analysis.  In the event that you want to have LUT intensity adjustments reflected in your line profile, you must apply the LUT to your bitmap using the Apply LUT command.
