Note: This topic is for Document/Medical only. The highlight annotation object (AnnHiliteObject) is a rectangle with default properties that are appropriate for highlighting an area. With the automated functions, the user clicks and drags to specify the rectangle in the current window. Programmatically, the boundaries and location of the highlight object can be controlled using the following properties:

• Rect
• Origin

The AnnHiliteObject class inherits a number of properties from the AnnObject class that provide support for font, stroke and fill characteristics. These properties are listed below:

• Fill
• FillBrush
• Stroke
• StrokeBrush
• StrokeThickness

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

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

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

• RenderTransform
• TransformMode

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 following properties can also be used to programmatically set characteristics of an AnnHiliteObject class object:

• Fill
• Hyperlink
• IsLocked
• Password
• IsVisible
