resetAnnotationManager()
resetAnnotationManager: () =>
void
Returns
void
addAnnotation()
Add the annotation to the annotation manager along with the options that is used to filter the annotation manager and the annotation group that the annotation belongs to.
As a result, our default implementation will add the annotation to the default manager using the FrameOfReferenceUID as the group key.
Parameters
• annotation: Annotation
The annotation that is being added to the annotations manager.
• annotationGroupSelector: AnnotationGroupSelector
element or FrameOfReferenceUID that is used to group annotations in the annotation manager.
Returns
string
addChildAnnotation()
Creates a parent/child association between annotations. A annotation may have only one parent and multiple children (eg: a contour may have multiple holes in it).
Parameters
• parentAnnotation: Annotation
Parent annotation
• childAnnotation: Annotation
Child annotation
Returns
void
clearParentAnnotation()
Removes the association between the annotation passed as parameter and its parent in case it has one (eg: contour holes).
Parameters
• annotation: Annotation
Annotation
Returns
void
getAllAnnotations()
Returns
getAnnotation()
Get the Annotation object by its UID
Parameters
• annotationUID: string
The unique identifier of the annotation.
Returns
getAnnotationManager()
It returns the default annotations manager.
Returns
any
the singleton default annotations manager.
getAnnotations()
Returns the annotations for a given tool with the provided options that is used to filter annotations based on the annotation manager.
In our default implementation, the options are the element and/or the FrameOfReferenceUID. Hence, the getAnnotations function will return the annotations for the given tool that are associated with the FrameOfReferenceUID.
Parameters
• toolName: string
The name of the tool.
• annotationGroupSelector: AnnotationGroupSelector
element or FrameOfReferenceUID that is used to group annotations in the annotation manager.
Returns
The annotations corresponding to the Frame of Reference and the toolName.
getChildAnnotations()
Returns all children annotation of a given one since annotations can be associated in a parent/child way (eg: polyline holes)
Parameters
• annotation: Annotation
Annotation
Returns
Child annotations
getNumberOfAnnotations()
Get the number of annotations for a given tool with the provided options that is used to filter annotations based on the annotation manager.
In our default implementation, the options are the element and/or the FrameOfReferenceUID. Hence, the getNumberOfAnnotations function will return the number of annotations for the given tool that are associated with the FrameOfReferenceUID.
Parameters
• toolName: string
The name of the tool
• annotationGroupSelector: AnnotationGroupSelector
element or FrameOfReferenceUID that is used to group annotations in the annotation manager.
Returns
number
getParentAnnotation()
Returns the parent annotation of a given one since annotations can be associated in a parent/child way (eg: polyline holes)
Parameters
• annotation: Annotation
Annotation
Returns
Parent annotation
invalidateAnnotation()
Invalidate current and all parent annotations (eg: contour holes)
Parameters
• annotation: Annotation
Annotation
Returns
void
removeAllAnnotations()
It removes all annotations from the default annotation manager
Returns
void
removeAnnotation()
Remove the annotation by UID of the annotation.
Parameters
• annotationUID: string
The unique identifier for the annotation.
Returns
void
removeAnnotations()
Removes all annotations associated with the specified group (FrameOfReferenceUID) and tool, or all annotations for the group (FrameOfReferenceUID) if the tool name is not provided.
Parameters
• toolName: string
Optional. The name of the tool to remove annotations for.
• annotationGroupSelector: AnnotationGroupSelector
The group (FrameOfReferenceUID) to remove annotations for.
Returns
void
setAnnotationManager()
Set the annotation manager to be used for rendering, adding, removing, etc.
Parameters
• annotationManager: IAnnotationManager
The annotation manager to be used
Returns
void
