Line Profile

Displays the grayscale distribution along a line of pixels in an image. Using the Line Tool, Broken Line Tool, or Freehand Line Tool from the toolbar, click and drag to draw a line segment.

Note  The Line Profile function analyzes the image and displays information for you to review. This function does not modify the image.

• Step Name—Name to give the step.
• Reposition Region of Interest—When enabled, the step dynamically repositions the region of interest based on a coordinate system you built in a previous step.
• Reference Coordinate System—Coordinate system to which you want to link the region of interest.

Line Profile Tab

The following controls are available on the Line Profile tab.

• Line Profile—Variations of intensity along a line.
• Minimum Value—Smallest pixel intensity found in the line profile.
• Maximum Value—Largest pixel intensity found in the line profile.
• Mean Value—Mean value of pixel intensities found in the line profile.
• Std Deviation—Standard deviation of pixel intensities from the line profile.
• Number of Pixels—Number of pixels found in the line profile.
• Mapping mode—Specifies if the vertical scale (y-axis) of the histogram is linear or logarithmic.
  • Linear—Displays the line profile in a linear scale.
  • Logarithmic—Displays the line profile in a logarithmic scale. Use the logarithmic scale if the linear values are too small to view.
