Note: This topic is for Document/Medical only. The freehand hot spot annotation object (AnnFreehandHotspotObject) is an array of points that creates a sequence of joined lines. With the automated functions, in design mode, each line segment is formed with a mouse move event when the left button is down, and the object is completed on a mouse up event. In run mode, the object is transparent, but the mouse pointer changes to a hand when it is over the object. You can change the points of a freehand object using the Points collection property. Programmatically, the boundaries and location of the freehand hotspot object can be controlled using the following properties:

• Origin
• Points

The AnnFreehandHotspotObject 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 name of the freehand 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 freehand 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 AnnFreehandHotspotObject class object:

• IsClosed
• FillRule
• Hyperlink
• IsLocked
• Password
• Picture
• SerializePassword
• Visiblility
