pdf-annotate.js

Annotation layer for pdf.js

Objectives

• Provide a low level annotation layer for pdf.js.
• Optional high level UI for managing annotations.
• Agnostic of backend, just supply your own StoreAdapter to fetch/store data.
• Prescribe annotation format.

Example

import __pdfjs from 'pdfjs-dist/build/pdf';
import PDFJSAnnotate from 'pdfjs-annotate';
import MyStoreAdapter from './myStoreAdapter';
 
const { UI } = PDFJSAnnotate;
const VIEWER = document.getElementById('viewer');
const RENDER_OPTIONS = {
  documentId: 'MyPDF.pdf',
  pdfDocument: null,
  scale: 1,
  rotate: 0
};
 
PDFJS.workerSrc = 'pdf.worker.js';
PDFJSAnnotate.setStoreAdapter(MyStoreAdapter);
 
PDFJS.getDocument(RENDER_OPTIONS.documentId).then((pdf) => {
  RENDER_OPTIONS.pdfDocument = pdf;
  VIEWER.appendChild(UI.createPage(1));
  UI.renderPage(1, RENDER_OPTIONS);
});
