Class: FrameOfReferenceSpecificAnnotationManager

This is the default annotation manager. It stores annotations by default based on the FrameOfReferenceUID. However, it is possible to override the getAnnotationStateKey function to store annotations based on any other property of the element. When you write your custom annotation manager, you can use the setAnnotationManager function to set your custom annotation.

Note that this class is a singleton and should not be instantiated directly. To get the stored annotations information you can use ToolState helpers.

Implements

• IAnnotationManager

Constructors

new FrameOfReferenceSpecificAnnotationManager()

new FrameOfReferenceSpecificAnnotationManager(uid?): FrameOfReferenceSpecificAnnotationManager

Parameters

• uid?: string

The uid of the state manager. If omitted it is autogenerated.

Returns

FrameOfReferenceSpecificAnnotationManager

Defined in

tools/src/stateManagement/annotation/FrameOfReferenceSpecificAnnotationManager.ts:40

Properties

uid

readonly uid: string

Defined in

tools/src/stateManagement/annotation/FrameOfReferenceSpecificAnnotationManager.ts:34

Methods

_imageVolumeModifiedHandler()

_imageVolumeModifiedHandler(evt): void

When a volume is modified we invalidate all of the annotations on the volume's FrameOfReferenceUID. This is mainly to update statistics calculations when an annotation is drawn whilst data is still loading.

Parameters

• evt: ImageVolumeModifiedEvent

The IMAGE_VOLUME_MODIFIED rendering event.

Returns

void

addAnnotation()

addAnnotation(annotation, groupKey?): void

Adds an annotation to the specified group.

Parameters

• annotation: Annotation

The annotation to add.

• groupKey?: string

The annotation group key to add the annotation to (in default manager it is FrameOfReferenceUID).

Returns

void

getAllAnnotations()

getAllAnnotations(): Annotations

return all annotations as a single array

Returns

Annotations

getAnnotation()

getAnnotation(annotationUID): Annotation

Returns the annotation with the specified UID.

Parameters

• annotationUID: string

The unique identifier of the annotation.

Returns

Annotation

The retrieved annotation.

IAnnotationManager.getAnnotation

Defined in

tools/src/stateManagement/annotation/FrameOfReferenceSpecificAnnotationManager.ts:159

---

getAnnotations()

getAnnotations(groupKey, toolName?): Annotations | GroupSpecificAnnotations

Returns the annotations associated with the specified group, if the toolName is specified, it will return the annotations for the specified tool.

Parameters

• groupKey: string

The annotation group key to retrieve annotations for (in default manager it is FrameOfReferenceUID).

• toolName?: string

Optional. The name of the tool to retrieve annotations for.

Returns

Annotations | GroupSpecificAnnotations

The annotations associated with the specified group (default FrameOfReferenceUID) and tool, or all annotations for the group (FrameOfReferenceUID) if the tool name is not provided. WARNING: The list returned here is internal tool data, not a copy, so do NOT modify it.

getFramesOfReference()

getFramesOfReference(): string[]

Returns all the available frameOfReferences inside the state manager

Returns

string[]

• All the added frames of references inside the manager

---

getGroupKey()

getGroupKey(annotationGroupSelector): string

Annotations are stored in Groups. Our default annotation manager groups the annotations based on FrameOfReferenceUID, but it is possible that you can group them based on different aspects or you only have one group totally.

This function returns the group key associated with the specified annotationGroupSelector. The annotationGroupSelector can be an HTML element or a string.

Parameters

• annotationGroupSelector: AnnotationGroupSelector

element or a string that is provided to the annotation manager to get the key.

Returns

string

• The annotation state key for the element.

---

getNumberOfAllAnnotations()

getNumberOfAllAnnotations(): number

Returns the total number of annotations across all groups.

Returns

number

---

getNumberOfAnnotations()

getNumberOfAnnotations(groupKey, toolName?): number

Returns the number of annotations associated with the specified group. If the toolName is specified, it will return the number of annotations

Parameters

• groupKey: string

The annotation group key to retrieve annotations for (in default manager it is FrameOfReferenceUID).

• toolName?: string

The name of the tool to retrieve data for.

Returns

number

The number of annotations for a given tool in the state

restoreAnnotations()

restoreAnnotations(state, groupKey?, toolName?): void

Restores a section of the annotations. Useful for loading in serialized data.

• If no arguments are given, the entire AnnotationState instance is restored.
• If the FrameOfReferenceUID is given, the corresponding FrameOfReferenceSpecificAnnotations instance is restored.
• If both the FrameOfReferenceUID and the toolName are are given, the corresponding Annotations instance is restored.

Parameters

• state: Annotations | GroupSpecificAnnotations | AnnotationState

• groupKey?: string

A filter string for restoring only the annotations of a specific frame of reference.

• toolName?: string

A filter string for restoring annotation for a specific tool on a specific frame of reference.

Returns

void

Defined in

tools/src/stateManagement/annotation/FrameOfReferenceSpecificAnnotationManager.ts:369

---

saveAnnotations()

saveAnnotations(groupKey?, toolName?): Annotations | GroupSpecificAnnotations | AnnotationState

Returns a section of the annotations. Useful for serialization. If both groupKey (default manager is FrameOfReferenceUID) and toolName are provided, returns the corresponding Annotations instance for that groupKey (FrameOfReferenceUID) and toolName. If only groupKey is provided, returns the corresponding FrameOfReferenceSpecificAnnotations instance for that groupKey. If neither groupKey nor toolName is provided, returns the entire AnnotationState object.

Parameters

• groupKey?: string

Optional. The group key (e.g. FrameOfReferenceUID) to retrieve annotations for.

• toolName?: string

Optional. The name of the tool to retrieve annotations for.

Returns

Annotations | GroupSpecificAnnotations | AnnotationState

A section of the annotations.
