Remarks

There are cases where the user may want to position a Point object dynamically and for that reason the Y1

property can also be set from the SPEL+ Language.

Line Object:

The Y1 property is used to locate vertical position for the starting point of a Line object. This property is

initially set to the Y position where the user drops a newly created Line object. However, if a Point object

is associated with another object in the sequence (i.e. the StartPointType property is set to another vision

object and not set to Screen), then the Y1 property for the Line object is automatically modified according

to the associated property.

When the StartPointType property is set to Screen there are 2 methods which can be used to move the Line

object:

- Click on the Line object's label and drag the object to the position you want to place it.

- Change the X1, Y1, X2, or Y2 coordinates.

Edge Object:

The Y1 property is used to locate veritical position for the starting point of an Edge object.
