Epson 5 LineObject1 Property

LineObject1 Property

LineObject1 Property

Applies To

Vision Objects: Point

Description

Specifies the 1st Line object to use for defining the position of a Point object. (LineObject1 defines the line

which is used by the PointType property for defining the position of the Point object. )

Usage

VGet Sequence.Object.LineObject1, var

VSet Sequence.Object.LineObject1, 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.

Values

Any Line object which is located prior to the Point object can be specified as the LineObject1 property

value.

Default: None

Remarks

When a Point object is first created, the default LineObject1 property is set to None. However, if you want

to position a point on the midpoint of a line, then the LineObject1 property defines which Line object to

use. In this case the LineObject1 property must be set first and then the PointType property can be set to

MidPoint. A MidPoint of a line can only be specified for LineObject1. (i.e. you cannot specify the

MidPoint of the LineObject2 property.)

LineObject1 can also be used to define the 1st of 2 lines when you want to define a Point object position as

the intersection point between 2 lines. (LineObject2 defines the other Line to use for the intersection point.)

It is important to note that for each specific vision sequence, only those Line objects which are executed

prior to the Point object in the vision sequence steps will be available to use as LineObject1. (The order of

the vision object execution can be adjusted from the Sequence Tab.)

NOTE

When using the point and click interface click on the LineObject1 property Value Field and a drop down

list will appear showing a list of available Line objects which can be used for the LineObject1 property.

Click on one of the choices and the value field will be set accordingly.

When using the Point-and-Click Object tab to set the LineObject1 property it is important to note that only

those objects which are defined prior to the Point object are displayed in the drop down list. This helps

reduce the chances of the user defining a Line object which isn't defined prior to the Point object.

)

NOTE Vision Guide automatically checks which vision objects may be used as LineObject1 and only displays

those items in the LineObject1 drop down list.
