trigger area.

moved and vertexes can be moved/added or deleted.
Capacity

trigger area.
The quantity is specified from the pull-down list.
Similar to a active window, the trigger area can also be
moved and its vertexes can also be moved, added or
deleted.
Minimum quantity: The quantity is specified from the
“Minimum quantity” pull-down.
Trigger size
Specify the minimum trigger size and maximum trigger
size of the object. To specify the size, you can either
enter values or drag the vertexes of the area.
The size of an object is measured in pixels.
• When you place the cursor on the area, the cursor
changes to a crossed arrow, which you can drag to
move the minimum trigger size area and maximum
trigger size area.
• Placing the cursor on the vertex of the minimum
trigger size area or maximum trigger size area will
change the cursor to n, then you can drag the vertex
to change the inspection size.
Tip
The minimum and maximum detection sizes configured
in the VMD setting are displayed, but the size of the area
cannot be modified from here.
