Note: This topic is for Document/Medical only. The hot spot annotation object (AnnHotspotObject) is a rectangle that can be activated for an application-defined purpose. With the automated functions, in design mode, the rectangle contains a scaled image. The user clicks and drags to specify the rectangle in the current window. In run mode, the object is transparent, but the mouse pointer changes to a hand when it is over the object. Programmatically, the boundaries and location of the hotspot object can be controlled using the following properties:

• Left
• Top
• Width
• Height
• Origin

The AnnHotspotObject class inherits a number of properties from the AnnObjectBase class that provide support for font, stroke and fill 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 name of the hotspot 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 hotspot 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 AnnHotspotObject class object:

• Hyperlink
• IsLocked
• Password
• Picture
• SerializePassword
• Visiblility
