Change the name of an element

I needed to know the name of an element is it possible?
and then retrieve the rect dimensions later or emit events every time that rect dimension changes


      const stampAnnot = new this.annotations.StampAnnotation();
      stampAnnot.PageNumber = 1;
      stampAnnot.X = 100;
      stampAnnot.Y = 250;
      stampAnnot.Width = 275;
      stampAnnot.Height = 275 * 0.359;

      const keepAsSVG = false;
      const svgData = await fetch(this.stamp + '/svg').then(r => r.text());
      stampAnnot.setImageData('data:image/svg+xml,' + encodeURIComponent(svgData), keepAsSVG);

      stampAnnot.Author = this.annotManager.getCurrentUser();
      stampAnnot.Rotation = 0;


Hi there,

Thanks for reaching out to pdf.js express forums,

The name of the annotation is the ID of the annotation. If you need to access specific annotations, we recommend you use the setCustomData method of the annotation:
