</h1>
  <div class="markdown level0 summary"><p>This class reads the file format wrapper that may or may not exist around a
valid JPEG 2000 codestream. Since no information from the file format is
used in the actual decoding, this class simply goes through the file and
finds the first valid codestream.</p>
