Annotation permissions

13 Feb 20266 minutes to read

Use annotationSettings to control creation-time permissions and default behavior for annotations in the PDF Viewer. These settings establish defaults for annotations created through the UI and programmatic flows.

Common permissions

  • isLock: Lock an annotation so it cannot be moved, resized, edited, or deleted.
  • skipPrint: Exclude annotations from the print output when printing from the viewer.
  • skipDownload: Exclude annotations from the exported/downloaded PDF.

Example: inject modules and create a viewer instance with default annotationSettings.

import { PdfViewer, Toolbar, Magnification, Navigation, LinkAnnotation, ThumbnailView, BookmarkView,
    TextSelection, TextSearch, Print, Annotation, FormFields, FormDesigner, 
    AllowedInteraction} from '@syncfusion/ej2-pdfviewer';

    PdfViewer.Inject(Toolbar,Magnification,Navigation, LinkAnnotation,ThumbnailView,BookmarkView,
    TextSelection, TextSearch, Print, Annotation,FormFields, FormDesigner);

let viewer: PdfViewer = new PdfViewer();
viewer.resourceUrl= 'https://cdn.syncfusion.com/ej2/31.1.23/dist/ej2-pdfviewer-lib';
viewer.documentPath= 'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf';

// Default annotation settings applied to annotations created via the UI
viewer.annotationSettings = {
  author: 'XYZ',
  minHeight: 10,
  minWidth: 10,
  maxWidth: 100,
  maxHeight: 100,
  isLock: false,        // allow moving/resizing/editing by default
  skipPrint: false,      // include annotations when printing the document
  skipDownload: false,   // include annotations when downloading/exporting the document
  allowedInteractions: [AllowedInteraction.Resize],
};

viewer.appendTo("#pdfViewer");

Individual permissions

  • isPrint: Controls whether a specific annotation participates in printing. Set to false to exclude only that annotation from print output.
  • isLock: Lock or unlock a specific annotation instance programmatically.

Example: create a viewer instance with per-annotation defaults for text markup, shapes, and measurements.

import { PdfViewer, Toolbar, Magnification, Navigation, LinkAnnotation, ThumbnailView, BookmarkView, TextSelection, Annotation, FormDesigner, FormFields } from '@syncfusion/ej2-pdfviewer';

PdfViewer.Inject(Toolbar, Magnification, Navigation, LinkAnnotation, ThumbnailView, BookmarkView, TextSelection, Annotation, FormDesigner, FormFields);

const pdfviewer: PdfViewer = new PdfViewer({
  documentPath: 'https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf',
  resourceUrl = "https://cdn.syncfusion.com/ej2/31.1.23/dist/ej2-pdfviewer-lib",
  // Text markup defaults
  highlightSettings: { author: 'QA', subject: 'Review', color: '#ffff00', opacity: 0.6 },
  strikethroughSettings: { author: 'QA', subject: 'Remove', color: '#ff0000', opacity: 0.6 },
  underlineSettings: { author: 'Guest User', subject: 'Points to be remembered', color: '#00ffff', opacity: 0.9 },
  squigglySettings: { author: 'Guest User', subject: 'Corrections', color: '#00ff00', opacity: 0.9 },

  // Shapes
  lineSettings: { strokeColor: '#0066ff', thickness: 2, opacity: 0.8, isLock: false, isPrint: true },
  arrowSettings: { strokeColor: '#0066ff', thickness: 2, opacity: 0.8, isLock: false, isPrint: true },
  rectangleSettings: { fillColor: '#ffffff00', strokeColor: '#222222', thickness: 1, opacity: 1, isLock: false, isPrint: true },
  circleSettings: { fillColor: '#ffffff00', strokeColor: '#222222', thickness: 1, opacity: 1, isLock: false, isPrint: true },
  polygonSettings: { fillColor: '#ffffff00', strokeColor: '#222222', thickness: 1, opacity: 1, isLock: false, isPrint: true },

  // Measurements
  distanceSettings: { strokeColor: '#0066ff', thickness: 2, opacity: 0.8, isLock: false, isPrint: true },
  perimeterSettings: { strokeColor: '#0066ff', thickness: 2, opacity: 0.8, isLock: false, isPrint: true },
  areaSettings: { strokeColor: '#0066ff', thickness: 2, opacity: 0.8, fillColor: '#ffffff00', isLock: false, isPrint: true },
  radiusSettings: { strokeColor: '#0066ff', thickness: 2, opacity: 0.8, fillColor: '#ffffff00', isLock: false, isPrint: true },
  volumeSettings: { strokeColor: '#0066ff', thickness: 2, opacity: 0.8, fillColor: '#ffffff00', isLock: false, isPrint: true },

  // Others
  freeTextSettings: { borderColor: '#222222', opacity: 1, isLock: false, isPrint: true },
  inkAnnotationSettings: { strokeColor: '#0000ff', thickness: 3, opacity: 0.8, isLock: false, isPrint: true },
  stampSettings: { opacity: 0.9, isLock: false, isPrint: true },
  stickyNotesSettings: { author: 'QA', subject: 'Review', opacity: 1, isLock: false, isPrint: true }
});

pdfviewer.appendTo('#PdfViewer');

Behavior notes

  • isLock true: The annotation is locked; users cannot move, resize, or edit it through the UI until it is unlocked.
  • skipPrint true: All annotations are omitted from the print output initiated from the viewer.
  • skipDownload true: All annotations are omitted from the exported/downloaded PDF from the viewer.
  • isPrint on an individual annotation: Use this when you only want to exclude a particular annotation from printing while leaving others printable.
