Impact Reference Guide Threshold Viewer
6-7 Datalogic Automation Inc.
The vertical red cursor is movable and shows the Greyscale or Gradient value at its location. A red hash
mark on the selected Line ROI follows the position of the red cursor on the plot.
Greyscale %
The percent greyscale, as shown graphically in the plot, at the red vertical line (cursor).
Grey Level Threshold (%)
The Grey Level Threshold (%) Minimum and Maximum fields work as follows:
When a Bright Line Type (e.g. First Bright Line) is selected in a tool, the Minimum field is editable and the
Maximum field is disabled and displays a fixed value of 100.0. When the green horizontal line (cursor) is
moved up or down, the Minimum threshold value is adjusted. When you type a value into the Minimum
field, the green cursor is adjusted. The Minimum value is reflected in the tool's "Fixed Grey Level Threshold
Percentage" property.
When a Dark Line Type (e.g. First Dark Line) is selected in a tool, the Maximum field is editable and the
Minimum field is disabled and displays a fixed value of 0.0. When the green cursor is moved up or down,
the Maximum threshold value is adjusted. When you type a value into the Maximum field, the green cursor
is adjusted. The Maximum value is reflected in the tool's "Fixed Grey Level Threshold Percentage" property.
Profile Type
Wide Circle Arc ROIs have an additional Profile Type selection: Radial and Arc
Radial Profile: When Radial Profile is selected, a radial line segment is shown on the ROI. Click and drag
the line segment to move it around the circle.The profile viewer shows the pixel values under the line seg-
ment.
The red hashmark on the
ROI corresponds to the
red cursor’s position.
