tools/src/tools/base/AnnotationDisplayTool.ts:134


doneEditMemo()

doneEditMemo(): void

This clears and edit memo storage to allow for further history functions to be called. Calls the complete function if present, and pushes the memo to the history memo stack.

This should be called when a tool has finished making a change which should be separated from future/other changes in terms of the history. Usually that means on endCallback (mouse up), but some tools also make changes on the initial creation of an object or have alternate flows and the doneEditMemo has to be called on mouse down or other initiation events to ensure that new changes are correctly recorded.

If the tool has no end callback, then the doneEditMemo is called from the pre mouse down callback. See ZoomTool for an example of this usage.

Returns

void

Inherited from

AnnotationDisplayTool.doneEditMemo

Defined in

tools/src/tools/base/BaseTool.ts:305


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)

getStyle()

getStyle(property, specifications, annotation?): unknown

getTargetId()

protected getTargetId(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.
