Epson 5 StartPointObject Property

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.
