271. Scan Pitch (Only for individual scans)
Set the interval in terms of pixels in the scanning direction at which
scanning is performed in the inspection area. The initial value is 1.
Setting a wide pitch makes inspection faster, but there is a greater
interval between the sections examined. If the pitch is set wider than the
scanning area, only a single line is scanned.
Scan pitch = 1
272. Filter
The filter function is a function that combines and makes one edge if the
interval between pixels where an edge was detected relative to the
scanning direction is less than the filter value.
273. Width (can only be set for individual scans)
The width function counts the detected number of edges in the vertical
direction relative to the scanning direction, calculates the sum of the
continuous edge counts, and if it is as large as or larger than the width
value, records it as an edge.
