title: Zoom in/Zoom out using React-PDF
body: <p>In my ReactJS application I need to add the functionality of zoom in/zoom out. I am using <a href="https://www.npmjs.com/package/react-pdf" rel="noreferrer">react-pdf</a> to display PDF in my web app. A/C to the <a href="https://github.com/wojtekmaj/react-pdf" rel="noreferrer">documentation</a> there is a <code>scale prop</code> by using which I can <code>scale</code> the pdf page. </p>
  
  <p>But using <code>scale prop</code> doesn't showing me any change in <code>zoom</code> factor. Here is the <code>code</code> which I am using to do so.</p>
  
  <pre><code>&lt;Document
          loading=""
          file={file}
          className="document"
          onLoadSuccess={(transport) =&gt; onLoadSuccess(transport, sectionIndex)}&gt;
          &lt;Page width={900} scale={30} className="page" pageNumber={1} /&gt;
      &lt;/Document&gt;
  </code></pre>
  
  <p>I have tried following values for <code>scale</code> <code>prop</code> but doesn't seem to get anything. 1.5, 0.5 , 10 , 30 ,40.
  Is there any better way of doing the same or I am missing something?</p>
