Threshold Viewer Impact Reference Guide
Datalogic Automation Inc. 6-6
The Threshold Viewer Window will display a grey level or gradient Line Profile, depending on the mode
chosen in the tool, for these ROI types: Arc, Line, and Wide Line. For details about the Histogram window,
see “Histogram” on page 6-2.
Title
The window title displays the current Profile Mode (Grey Level or Gradient), the Tool or Task name, and the
current threshold mode being used (when applicable).
Grey Level Mode - Adjustable Threshold
Line Profile Plot
The grey level Line Profile is displayed as a line plotted on a graph where the X-Axis represents the length
of the selected line ROI and the Y-Axis represents the line’s grey level percent from zero percent (black) to
100 percent (white).
The horizontal green cursor represents the tool's Grey Level Threshold Minimum or Maximum percent
(based on bright or dark line type). When the green cursor is adjusted, the threshold percent in the tool's
property is also adjusted. If Pseudocolor is turned on, adjusting the green cursor will adjust the threshold
limits on the image display. If the tool is in Autothreshold mode, the green cursor is only displayed when the
Pseudocolor is ON, it will then only adjust the image display's threshold limits and NOT the tool's property
values.
