Note: This topic is for Document/Medical only. The text pointer annotation object (AnnTextPointerObject) extends the AnnTextObject class by providing an extra line that starts from one of the four corners of the bounding rectangle around the text. The other endpoint of the line can be moved to point to anything on the underlying image. This extra endpoint may or may not be fixed. Programmatically, the boundaries and location of the text pointer object can be controlled using the following properties:

• Left
• Top
• Width
• Height
• IsFixedPointer
• Origin

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

• Fill
• Stroke
• StrokeDashArray
• StrokeDashCap
• StrokeDashOffset
• StrokeEndLineCap
• StrokeLineJoin
• StrokeMiterLimit
• StrokeStartLineCap
• StrokeThickness
• FontDecorations
• FontFamily
• FontSize
• FontStretch
• FontStyle
• FontWeight
• SupportsFill
• SupportsFont
• SupportsStroke

The AnnTextPointerObject class inherits a number of text properties from the AnnTextObject class that provide support for text alignment, margins, etc. These properties are listed below:

• TextHorizontalAlignment
• EdgeMargin
• TextVerticalAlignment
• Text
• IsTextImplemented
• TextBrush
• TextRotate

The name of the text pointer object can be controlled using the following properties, inherited from the AnnObjectBase class:

• Header
• HeaderBackground
• HeaderDecorations
• HeaderFontFamily
• HeaderFontSize
• HeaderFontStretch
• HeaderFontStyle
• HeaderFontWeight
• HeaderForeground
• HeaderOffset
• IsHeaderRestricted
• IsHeaderVisible

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

• RenderTransform
• 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 AnnObjectBase 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 AnnTextPointerObject class object:

• Hyperlink
• IsLocked
• Password
• PointerPosition
• SerializePassword
• Visiblility
