Adding a sticky note annotation to the PDF document Programmatically

With the PDF Viewer library, you can add a sticky note annotation to the PDF Viewer control programmatically using the addAnnotation() method.

Here’s a example of how you can utilize the addAnnotation() method to include a sticky note annotation programmatically:

import { Component, OnInit } from '@angular/core';
import { LinkAnnotationService, BookmarkViewService,
         MagnificationService, ThumbnailViewService, ToolbarService,
         NavigationService, TextSearchService, TextSelectionService,
         PrintService, FormDesignerService, FormFieldsService, 
         AnnotationService, PageOrganizerService, StickyNotesSettings } from '@syncfusion/ej2-angular-pdfviewer';

@Component({
  selector: 'app-root',
  // specifies the template string for the PDF Viewer component
  template: `<div class="content-wrapper">
  <button (click)="addAnnotation()">Add StickyNotes Programmatically</button>
  <ejs-pdfviewer 
    id="pdfViewer" 
    [documentPath]='document' 
    [resourceUrl]='resource' 
    style="height:640px;display:block">
  </ejs-pdfviewer>
</div>`,
  providers: [ LinkAnnotationService, BookmarkViewService, MagnificationService,
               ThumbnailViewService, ToolbarService, NavigationService,
               TextSearchService, TextSelectionService, PrintService,
               AnnotationService, FormDesignerService, FormFieldsService, PageOrganizerService]
})
export class AppComponent implements OnInit {
    public document = 'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf';
    public resource: string = "https://cdn.syncfusion.com/ej2/25.1.35/dist/ej2-pdfviewer-lib";
    ngOnInit(): void {
    }
    addAnnotation() {
      var pdfviewer = (<any>document.getElementById('pdfViewer')).ej2_instances[0];
      pdfviewer.annotation.addAnnotation("StickyNotes", {
        offset: { x: 100, y: 200 },
        pageNumber: 1,
        isLock: false
    } as StickyNotesSettings);
  }
}
import { Component, OnInit } from '@angular/core';
import { LinkAnnotationService, BookmarkViewService,
         MagnificationService, ThumbnailViewService, ToolbarService,
         NavigationService, TextSearchService, TextSelectionService,
         PrintService, FormDesignerService, FormFieldsService, 
         AnnotationService, PageOrganizerService, StickyNotesSettings } from '@syncfusion/ej2-angular-pdfviewer';

@Component({

               TextSearchService, TextSelectionService, PrintService,
               AnnotationService, FormDesignerService, FormFieldsService, PageOrganizerService]

      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]);
        }
