A circular annulus section is a four-sided shape bounded by two circular arcs and two radial lines. The arcs are scaled copies of each other, and the radial lines connect the endpoints of the arcs. You specify the ( CenterX, CenterY ), Radius, AngleStart and AngleSpan which define the start arc and then provide a RadialScale that defines the end arc. If the RadialScale is less than 1, the start arc is the outer arc.

The CircularAnnulusSection type exposes the following members.
| Name | Description | |
|---|---|---|
| CircularAnnulusSection | Constructs a new instance of this class. |
| Name | Description | |
|---|---|---|
| Copy | Creates a new circular annulus section, copying the specified parameters. | |
| CopyBase | Copy a graphic and its derived parameters. | |
| CreateCircularArc | Creates a new circular arc (copying the specified parameters) defined by this circular annulus section at the given radial fraction between the start and end arcs. For example, specify 0 for the start arc, 0.5 for the center arc, and 1 for the end arc. | |
| DistanceToPoint | Shortest distance from a boundary of this shape to the given point. Points within closed shapes return a distance less than zero. | |
| EnclosingRectangle | Minimum enclosing rectangle of this shape. | |
| Equals | Compares the equality of this object with another. (Overrides GraphicInteractiveBase Equals(Object).) | |
| FitToBoundingBox | Adjust the shape's geometric properties so that the shape fits inside passed in rectangle. | |
| FitToImage | Adjust the shape's geometric properties such that its default size is based on the image and its SelectedSpaceName. XScale and YScale are multipliers where 1.0 designates 100% scaling. | |
| GetCenterRadiusAngleStartAngleSpanRadialScale | Gets CenterX, CenterY, Radius, AngleStart (in radians), AngleSpan (in radians) and RadialScale of the circular annulus section. | |
| GetCornerWidthHeightRotationCurve | Gets corner, width, height, rotation and curvature of the circular annulus section. | |
| GetHashCode | Returns the hash code of this object. (Overrides GraphicInteractiveBase GetHashCode .) | |
| GetParentFromChildTransform | Gets the parent transform from the child transform. | |
| GetType | Gets the Type of the current instance. (Inherited from Object.) | |
| GetTypeMeta | Get the TypeMeta that describes the type of this object. | |
| Map | Maps this shape through the given transform. | |
| MapLinear | Creates a new elliptical annulus section (copying the specified parameters) by mapping this circular annulus section through the given linear transform. | |
| ResumeAndRaiseChangedEvent | Re-enables raising of the ChangedEvent after SuspendChangedEvent has been called, and raises the ChangedEvent if the ChangedEventSuspended count is reduced to zero and any changes were made while events were suspended. Must be called once for each call to SuspendChangedEvent. | |
| SetCenterRadiusAngleStartAngleSpanRadialScale | Sets CenterX, CenterY, Radius, AngleStart (in radians), AngleSpan (in radians) and RadialScale of the circular annulus section. | |
| SetCornerWidthHeightRotationCurve | Sets corner, width, height, rotation and curvature of the circular annulus section. | |
| SuspendChangedEvent | Temporarily suspends the raising of the ChangedEvent. May be called more than once, and a corresponding call to ResumeAndRaiseChangedEvent must be made for each call to SuspendChangedEvent. | |
| ToString | Returns a human readable string that represents the object. |
| Name | Description | |
|---|---|---|
| Equality | Compares the equality of two CircularAnnulusSection objects. | |
| Inequality | Compares the inequality of two CircularAnnulusSection objects. |

| AngleSpan | Get Gets the angle span (in radians) of this annulus section. Note that this can be positive or negative, and implies arc direction. | |
| AngleStart | Get Gets the starting angle (in radians) of this annulus section. | |
| ArcDirectionAdornment | Get Gets the arc direction adornment of this annulus section. | |
| Area | Returns the area enclosed by this circular annulus section. | |
| CenterArcAdornment | Get Gets the center arc adornment of this annulus section. | |
| CenterX | Get Gets the X coordinate of the center of the circle defined by this circular annulus section. | |
| CenterY | Get Gets the Y coordinate of the center of the circle defined by this circular annulus section. | |
| ChangedEventSuspended | Indicates if raising the ChangedEvent has been suspended. | |
| Children | Children of this graphic. | |
| Color | Color of this graphic. Can be any OLE_COLOR. | |
| DragColor | Color of this graphic when dragged. | |
| DragLineStyle | Line style of the graphic when dragged. | |
| DragLineWidthInScreenPixels | Line width of this graphic when dragged. | |
| FillColor | The fill color of this graphic. | |
| GraphicDOFEnable | Get Interactive Degree of freedom for this graphic object. Provides the ability to govern interactive manipulation of an object; for example could be used to prevent an object from being resized. | |
| GraphicDOFEnableBase | Interactive Degree of freedom for a graphic object. Allows access to each graphic's GraphicDOFEnable property without knowing the specific graphic type. | |
| Handle | (Overrides GraphicInteractiveBase Handle.) | |
| Interactive | Interactive property allow this graphic object to be selected. See GraphicDOFEnable for information on governing interactive manipulation of an object. | |
| LineStyle | Line style of this graphic. | |
| LineWidthInScreenPixels | Line width (in screen pixels) of this graphic. | |
| ManipArcFraction | Get Returns the fractional distance (between the start and end arcs) where the manipulation arc is drawn. During interactive manipulation, the shape usually resets this fraction to 0.5 but users may reset it sooner if they desire. | |
| MouseCursor | Mouse cursor to be displayed when the mouse is over the graphic. The cursor will be visible only if the graphic is interactive. | |
| Parent | Return a reference to the containing tracking collection. May be null. | |
| Perimeter | Returns the perimeter length of this circular annulus section. | |
| RadialDirectionAdornment | Get Gets the radial direction adornment of this annulus section. | |
| RadialScale | Get Gets the radial scale of this annular section. Note that this can be less than or greater than 1 (but not equal to 1, and not <=0) and therefore implies a radial direction. | |
| Radius | Get Gets the Radius of the start arc of this annulus section. Note this could be either the inner arc or the outer arc depending on whether RadialScale is greater than or less than 1.0. | |
| Selected | True when the shape is selected in a display. | |
| SelectedColor | Color of this graphic when selected. | |
| SelectedLineStyle | Line style of this graphic when selected. | |
| SelectedLineWidthInScreenPixels | Line width of this graphic when selected. | |
| SelectedSpaceName | Get (Overrides GraphicInteractiveBase SelectedSpaceName.)Coordinate space in which this shape is to be interpreted. | |

| Dragging | Raised when an interactive graphic is being dragged. | |
| DraggingStopped | Raised after the drag operation of an interactive graphic is complete. |
