Note: This topic is for Document/Medical only. The line annotation object (AnnLineObject) is a simple line. With the automated functions, the line is started on a mouse-down event and completed on a mouse-up event. Programmatically, the boundaries and location of the line object can be controlled using the following properties:

• BoundingRectangle
• EndPoint
• InvalidRectangle
• Origin
• StartPoint

The AnnLineObject class inherits a number of properties from the AnnDrawable class that provide support for font, pen and brush characteristics. These properties are listed below:

• Brush
• Font
• HasBrush
• HasFont
• HasPen
• Pen
• SupportsBrush
• SupportsFont
• SupportsPen

The name of the line object can be controlled using the following properties, inherited from the AnnObject class:

• Name
• NameBackColor
• NameFont
• NameForeColor
• NameOffset
• NameRestrict
• NameVisible

The following properties may be used in transforming a line annotation object:

• PhysicalTransform
• Transform
• TransformObjectMode

An object can be part of a group annotation object or part of a container object. It cannot be part of both a group and a container at the same time. The Container property and the Group property, both inherited from the AnnObject class, contain information on the container or the group to which the object belongs. The following properties can also be used to programmatically set characteristics of an AnnLineObject class object:

• HitTestInterior
• Hyperlink
• IsLocked
• Password
• SerializePassword
• TextColor
• UnitConverter
• UserData
• Visible

Note: You can not create a line of two points which they are the same.
