    • config: any
    • evt: any

    Returns void

publicstaticcreateAndAddAnnotation

  • createAndAddAnnotation(viewport: any, ...annotationBaseData: any[]): void

  • Creates and adds an annotation of the given type, firing the annotation modified event on the new annotation. This implicitly uses the static class when you call it on the correct base class. For example, you can call the KeyImageTool.createAnnotation method on KeyImageTool.toolName by calling KeyImageTool.createAndAddAnnotation

    Parameters

    • viewport: any
    • rest...annotationBaseData: any[]

    Returns void

publicstaticcreateAnnotation

  • createAnnotation(...annotationBaseData: any[]): Annotation

    • rest...annotationBaseData: any[]

    Returns Annotation

publicstaticcreateAnnotationForViewport

  • createAnnotationForViewport(viewport: any, ...annotationBaseData: any[]): Annotation

  • Creates a new annotation for the given viewport. This just adds the viewport reference data to the metadata, and otherwise returns the static class createAnnotation data.
