Here’s a example of how you can utilize the addAnnotation() method to include a sticky note annotation programmatically:
import * as ReactDOM from 'react-dom';
import * as React from 'react';
import './index.css';
import { PdfViewerComponent, Toolbar, Magnification, Navigation, LinkAnnotation, BookmarkView, ThumbnailView,
Print, TextSelection, TextSearch, Annotation, FormFields, FormDesigner, PageOrganizer, Inject } from '@syncfusion/ej2-react-pdfviewer';
let pdfviewer;
function App() {
function addAnnotation() {
var viewer = document.getElementById('container').ej2_instances[0];
viewer.annotation.addAnnotation("StickyNotes", {
offset: { x: 100, y: 200 },
pageNumber: 1,
isLock: false
});
}
return (<div>
<button onClick={addAnnotation}>Add Annotation programatically</button>
<div className='control-section'>
<PdfViewerComponent
ref={(scope) => { pdfviewer = scope; }}
id="container"
documentPath="https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf"
resourceUrl="https://cdn.syncfusion.com/ej2/25.1.35/dist/ej2-pdfviewer-lib"
style={{ 'height': '640px' }}>
<Inject services={[ Toolbar, Annotation, Magnification, Navigation, LinkAnnotation, BookmarkView, ThumbnailView,
Print, TextSelection, TextSearch, FormFields, FormDesigner, PageOrganizer]} />
</PdfViewerComponent>
</div>
</div>);
}
const root = ReactDOM.createRoot(document.getElementById('sample'));
root.render(<App />);
import * as ReactDOM from 'react-dom';

function App() {
function addAnnotation() {
var viewer = document.getElementById('container').ej2_instances[0];
viewer.annotation.addAnnotation("StickyNotes", {
offset: { x: 100, y: 200 },
pageNumber: 1,
isLock: false
});
}

Print, TextSelection, TextSearch, Annotation, FormFields, FormDesigner, PageOrganizer, Inject } from '@syncfusion/ej2-react-pdfviewer';
let pdfviewer;
function App() {
function editAnnotation() {
var viewer = document.getElementById('container').ej2_instances[0];
for (let i = 0; i < viewer.annotationCollection.length; i++)
{
if (viewer.annotationCollection[i].shapeAnnotationType === "sticky") {
var width = viewer.annotationCollection[i].bounds.width;
var height = viewer.annotationCollection[i].bounds.height;
viewer.annotationCollection[i].bounds = {x : 100, y: 100, width: width, height: height };
viewer.annotation.editAnnotation(viewer.annotationCollection[i]);
}
}
}
