Protractor Annotation Object

Note:

This topic is for Document/Medical only.

The protractor annotation object (ANN_OBJECT_PROTRACTOR) 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.

For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.

With low-level functions, you must define the size and position of the rectangle. Other applicable properties have the following defaults, which you can change:

Visible	Defaults to FALSE. It can be changed using the AnnSetVisible method.
Selected	Defaults to FALSE. It can be changed using the AnnSetSelected method.
Name	Defaults to an empty string. It can be changed using the AnnSetNameOptions method.
Line width	Defaults to 0.75 points. It can be changed using the AnnSetLineWidth method. (Note that when displayed, the line must have a minimum width of 1 pixel.)
Line style	Defaults to solid. It can be changed using the AnnSetLineStyle method.
ROP2 code	Defaults to ANN_ROP2_COPY. It can be changed using the AnnSetROP2 method.
Fill mode	Defaults to transparent. It can be changed using the AnnSetFillModeExt method. For version 14.5, before calling this method enable the alpha background fill mode by calling the AnnSetOptions method.
Foreground color	Defaults to red. It can be changed using the AnnSetForeColor method.
Background color	Defaults to white. It can be changed using the AnnSetBackColor method. The default does not affect highlight, redaction, or note objects.
Ruler show flags	Defaults to not show the Length, the Gauge or the Tic Marks. These options can be changed using the AnnSetShowFlags method, the AnnSetGaugeLength method, and the AnnSetUnit method.
Protractor	Defaults to displaying the inside (acute) angle, measured in degrees, to a precision of two places right of the decimal, and an arc radius of 30. These settings can be changed using the AnnSetProtractorOptions method. To retrieve the current values, use the AnnGetProtractorOptions method.
Fixed State	Defaults to not fixed. It can be changed using the AnnFixed property.
Hyperlink	Defaults to None. It can be changed using the AnnSetHyperlinkString method.
Tag (identifier)	Defaults to 0. It can be changed using the AnnSetTag method.
Window handle	Defaults to NULL or the handle inherited from the container. It can be changed for all objects using the AnnSetWnd method.
User mode	Defaults to design mode or the mode inherited from the container. It can be changed for all objects using the AnnUserMode property.

To get the angle of the Protractor object in the object's unit of measurement, use AnnGetAngle method
