title: Tesseract and tiff format - spp not in set {1,3}
body: <p>While trying to run this command:</p>
  
  <pre><code>tesseract bond111.tif bond111 batch.nochop makebox
  </code></pre>
  
  <p>I get the next error</p>
  
  <pre><code>Error in pixReadFromTiffStream: spp not in set {1,3}
  Error in pixReadStreamTiff: pix not read
  Error in pixReadTiff: pix not read
  </code></pre>
  
  <p>Assuming that <code>spp not in set</code> is the main error here, what does it mean?
   At first it had trouble because the bpp was higher than 24 so I reduced it using Gimp but that did not resolve the issue.</p>
