Open a document from ArrayBuffer

Opening a document from ArrayBuffer

If your document is already in ArrayBuffer format you can convert the ArrayBuffer object to a Blob and then pass resulting Blob directly to loadDocument function.

1WebViewer(...)
2  .then(instance => {
3
4    // `arrayBuffer` is your buffer data which can come
5    // from sources such as a server or the filesystem
6    const arr = new Uint8Array(arrayBuffer);
7    const blob = new Blob([arr], { type: 'application/pdf' });
8    instance.UI.loadDocument(blob, { filename: 'myfile.pdf' });
9
10    const { documentViewer } = instance.Core;
11    documentViewer.addEventListener('documentLoaded', () => {
12      // perform document operations
13    });
14  });
