StartPointType Property
StartPointType Property
Applies To
Vision Objects: Edge, Line
Description
Specifies the type of start point to use for the line object. In most cases the start point type will be a point
(which usually means the PixelX and PixelY position of the StartPointObject). However, when the
StartPointObject for the current line is a 2nd Line object, the StartPointType property is used to define an
intersection point on the 2nd line such as the lines midpoint, endpoint, startpoint or perpendicular position.

VSet Sequence.Object.StartPointType, value

When used with objects other than the Line object, the StartPointType can
only be of type 0 - Point.
