StartPointObject Property
StartPointObject Property
Applies To
Vision Objects: Edge, Line
Description
Specifies the vision object to connect the starting point of the Line to. (i.e. This property defines the
position of the start point of the line.)
Usage
VGet Sequence.Object.StartPointObject, var
VSet Sequence.Object.StartPointObject, value
Sequence Name of a sequence or string variable containing a sequence name.
Object Name of an object or string variable containing an object name. The object must exist in the
specified sequence.
var String variable that will contain the value of the property.
value String expression for the new value of the property. Valid vision objects for the
StartPointObject property are: Blob, Correlation, Edge, Geometric, Line, and Point objects.
Values
Screen or any object that runs prior to the Line object.
Remarks
When a Line object is first created, the StartPointObject property is set to Screen. However, Line objects
are normally attached to other vision objects. This is the purpose of the StartPointObject and
EndPointObject properties. Through these two properties the user can define a line between any two vision
objects (except Frames).
Frame objects cannot be used to define an start point for a Line object. However, this does not cause a
limitation because Frames are defined by other vision objects. In those cases where you want to define a
line start point with a Frame object, use a Point object in the frame to define the start point of the Line
object.
It is important to note that for each specific vision sequence, only those vision objects which are executed
prior to the Line object in the vision sequence steps will be available to use as an StartPointObject.
