The protractor annotation object (AnnProtractorObject) consists of two simple lines joined at a vertex to create an angle. With the automated functions, the first line of the protractor is started on a mouse-down event and completed on a second mouse-down event. The second line is completed on a third mouse-down event.
Programmatically, the boundaries and location of the protractor object can be controlled using the following properties:
The AnnProtractorObject 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 AnnProtractorObject class implements the IAnnProtractorObject interface. This interface provides a number of protractor properties that control certain aspects of the protractors themselves and indicate which characteristics will be displayed on the protractor. These properties are listed below:
The AnnProtractorObject class implements the IAnnRulerObject interface. This interface provides a number of ruler properties that control certain aspects of the rulers themselves and indicate which characteristics will be displayed on the ruler. These properties are listed below:
GaugeLength MeasurementUnit Precision IsRulerImplemented ShowGauge ShowLength ShowTickMarks TickMarksLength UnitAbbreviation
The name of the protractor 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 protractor annotation object:
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 AnnProtractorObject class object:
