filterInteractableAnnotationsForElement()
filterInteractableAnnotationsForElement(
element,annotations):Annotations
Given the element and annotations which is an array of annotation, it filters the annotations array to only include the annotation based on the viewportType. If the viewport is StackViewport, it filters based on the current imageId of the viewport, if the viewport is volumeViewport, it only returns those that are within the same slice as the current rendered slice in the volume viewport. imageId as the enabledElement.
Parameters
• element: HTMLDivElement
The HTML element
• annotations: Annotations
The annotations to filter (array of annotation)
Returns
The filtered annotations

getStyle()
getStyle(
property,specifications,annotation?):unknown
It takes the property (color, lineDash, etc.) and based on the state of the annotation (selected, highlighted etc.) it returns the appropriate value based on the central toolStyle settings for each level of specification.
Parameters
• property: string
The name of the style property to get.
• specifications: StyleSpecifier
• annotation?: Annotation
The annotation for the tool that is currently active.
Returns
unknown
The value of the property.

getTargetId()
protectedgetTargetId(viewport):string
Get the target Id for the viewport which will be used to store the cached statistics scoped to that target in the annotations. For StackViewport, targetId is the viewportId, but for the volume viewport, the targetId will be grabbed from the volumeId if particularly specified in the tool configuration, or if not, the first actorUID in the viewport.
Parameters
• viewport: Viewport
viewport to get the targetId for
Returns
string

getTargetImageData()
protectedgetTargetImageData(targetId):IImageData|CPUIImageData
Get the image that is displayed for the targetId in the cachedStats which can be
imageId:<imageId>volumeId:<volumeId>videoId:<basePathForVideo>/frames/<frameSpecifier>
Parameters
• targetId: string
annotation targetId stored in the cached stats
Returns
IImageData | CPUIImageData
The image data for the target.

onImageSpacingCalibrated()
onImageSpacingCalibrated(
evt):void
On Image Calibration, take all the annotation from the AnnotationState manager, and invalidate them to force them to be re-rendered and their stats to be recalculated. Then use the old and new imageData (non-calibrated and calibrated) to calculate the new position for the annotations in the space of the new imageData.
Parameters
• evt: ImageSpacingCalibratedEvent
The calibration event
