Example of Annotations in Blazor PDF Viewer Component
This example illustrates the creation of various types of annotations programmatically in the SfPdfViewer, including Text Markup, Shapes, Measurements, Free text, Stamps, Handwritten signature, ink, and sticky notes. We can customize the added annotations or we can include new annotations through user interaction from the SfPdfViewer.
