StampAnnotation

Adding stamp annotations to the PDF document

The stamp annotations can be added to the PDF document using the annotation toolbar.

  • Click the Edit Annotation button in the PDF Viewer toolbar. A toolbar appears below it.
  • Click the Stamp Annotation drop-down button. A drop-down pop-up will appear and shows the stamp annotations to be added.

StampTool

  • Select the annotation type to be added to the page in the pop-up.

StampPopup

  • You can add the annotation over the pages of the PDF document.

NOTE

While you’re in the pan mode, for navigating through the document, and you click on the stamp annotation button to add the stamp annotation , the PDF Viewer control will smoothly transition to text select mode. This seamless transition ensures a fluid experience when switching between different interaction modes within the PDF Viewer interface.

Refer to the following code sample to switch to the stamp annotation mode.

CustomStamp

  • The file explorer dialog will appear, choose the image and then add the image to the PDF page.

The JPG and JPEG image format is only supported in the custom stamp annotations.

Adding a Stamp annotation to the PDF document Programmatically

With the PDF Viewer library, you can add a Stamp 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 Stamp annotation programmatically:

    <button id="dynamicStamp">Add Sign Stamp Programmatically</button>
    <button id="signStamp">Add Sign Stamp Programmatically</button>
    <button id="standardBusinessStamp">Add StandardBusiness Stamp Programmatically</button>
    <button id="customStamp">Add Custom Stamp Programmatically</button>

Setting default properties during control initialization

The properties of the stamp annotation can be set before creating the control using the StampSettings.

After editing the default opacity using the Edit Opacity tool, they will be changed to the selected values.
Refer to the following code sample to set the default sticky note annotation settings.

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

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

let pdfviewer: PdfViewer = new PdfViewer();
pdfviewer.documentPath = "https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf";
pdfviewer.resourceUrl = "https://cdn.syncfusion.com/ej2/25.1.35/dist/ej2-pdfviewer-lib";
pdfviewer.stampSettings = {opacity: 0.3, author: 'Guest User'}

pdfviewer.appendTo('#PdfViewer');
