Annotation Numbering

WebViewer has an option to automatically number annotations as you create them. When enabled, whenever you create an annotation or import one, it will receive the next available number, starting at 1. This associated number will be displayed for each annotation in the notes panel, allowing for easier tracking when working with a large amount of them.

You can enable this functionality by setting the webviewer option enableAnnotationNumbering

JavaScript

WebViewer({
    path: 'lib',
    initialDoc: 'https://pdftron.s3.amazonaws.com/downloads/pl/demo-annotated.pdf',
    enableAnnotationNumbering: true,
}, viewerElement).then((instance) => {
    // call apis here
})
