Hi ,  
I want to change default user name ‘Guest’ to other name at runtime. i.e if user draws any annotation then after each drawn annotation i want to change or add user name to it.  
So is it possible to change user name at runtime for each annotation drawn ?

Could you please share relevant documentation for the same (if available).

Hey there!

You can use the [AnnotationManager.setCurrentUser](https://pdfjs.express/api/CoreControls.AnnotationManager.html#setCurrentUser__anchor) API to change the name of the current user. This will apply to any new annotations.

For more fine grained control, you can use the [AnnotationManager.setAnnotationDisplayAuthorMap](https://pdfjs.express/api/CoreControls.AnnotationManager.html#setAnnotationDisplayAuthorMap__anchor) function.

Hope this helps!
