How to save and restore annotation state

ArgoKnight · August 22, 2024, 10:16am

I want to save and restore annotation state in cornerstone in a persistent way
Save state into something like a BD and restoring it again whenever I want
I’m currently trying the most primitive option, converting the result of cornerstoneTools.annotation.state.getAnnotationManager().saveAnnotations() into json and storing it, but it isn’t working when I try to restore it
