title: Tesseract multiple output format
body: <p><strong>My context</strong></p>
  
  <p>I'm using tesseract to extract text from an image.</p>
  
  <p>I'm generating a <em>.tsv</em> to retrieve the extracted text and perform some regex on it and a <em>.pdf</em> to have a searchable pdf.</p>
  
  <p>The way I do it is by calling tesseract 2 times:</p>
  
  <ul>
  <li>One asking for the .tsv</li>
  <li>One asking for the .pdf</li>
  </ul>
  
  <p>But I feel like this is not very efficient (the same computations must be made two times)</p>
  
  <p><strong>What I wish</strong></p>
  
  <p>I wish to make my computations go faster. And my idea is to call tesseract only once but specifying two output formats</p>
  
  <p>Is it possible? If so how? </p>
