Annotation layer for pdf.js

@submitty/pdf-annotate.js

Annotation layer for PDF.js.

Combined fork of archived instructure/pdf-annotate.js and deleted DynamicEnvironmentSystems/pdf-annotate.js. Under active development for usage within Submitty.

To report issues for pdf-annotate.js, please file them under the Submitty/Submitty repository.

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.

Installation

npm install @submitty/pdf-annotate.js

Example

import pdfjsLib from 'pdfjs-dist/build/pdf';
import PDFJSAnnotate from 'pdfjs-annotate';

const { UI } = PDFJSAnnotate;
const VIEWER = document.getElementById('viewer');
const RENDER_OPTIONS = {
  documentId: 'MyPDF.pdf',
  pdfDocument: null,
  scale: 1,
  rotate: 0
};

pdfjsLib.GlobalWorkerOptions.workerSrc = 'pdf.worker.js';
PDFJSAnnotate.setStoreAdapter(new PDFJSAnnotate.LocalStoreAdapter());

pdfjsLib.getDocument(RENDER_OPTIONS.documentId).promise.then((pdf) => {
  RENDER_OPTIONS.pdfDocument = pdf;
  VIEWER.appendChild(UI.createPage(1));
  UI.renderPage(1, RENDER_OPTIONS);
});

See /web for an example web client for annotating PDFs.
