The PDF Viewer includes magnification controls—ZoomIn, ZoomOut, Zoom, FitPage, and FitWidth—in the default toolbar. The magnification controls can be shown or hidden in the toolbar.

The following examples show how to enable magnification in the PDF Viewer.

  <div id="app">
    <ejs-pdfviewer id="pdfViewer" :documentPath="documentPath" :resourceUrl="resourceUrl" :enableMagnification="true">
    </ejs-pdfviewer>
  </div>
</template>

<script setup>
import {
  PdfViewerComponent as EjsPdfviewer, Toolbar, Magnification, Navigation,
  LinkAnnotation, BookmarkView, Annotation, ThumbnailView,
  Print, TextSelection, TextSearch
} from '@syncfusion/ej2-vue-pdfviewer';
import { provide } from 'vue';

const documentPath = "https://cdn.syncfusion.com/content/pdf/pdf-succinctly.pdf";
const resourceUrl = "https://cdn.syncfusion.com/ej2/31.2.2/dist/ej2-pdfviewer-lib";

provide('PdfViewer', [Toolbar, Magnification, Navigation, LinkAnnotation, BookmarkView,
  Annotation, ThumbnailView, Print, TextSelection, TextSearch])
