@Jason_Hostetter: When saving all annotations, i.e. with cornerstoneTools.annotation.state.getAnnotationManager().saveAnnotations(), the ROI tools use cachedStats to store the calculated stats, but they also appear to cache pointsInShape, which is it seems metadata about every pixel included in the ROI, which when serialized can balloon the data to multiple megabytes for just one ROI. Does pointsInShape need to be included in cachedStats?
@Rod_Fitzsimmons_Frey: My application is stripping that data without any bad effects.
@Alireza_Sedghi: I just merged a PR for this
