title: The "value offset" field of an IFD entry with a rational type can only hold an offset?
body: <p>Consider an IFD entry with a rational type (UNSIGNED RATIONAL or SIGNED RATIONAL).</p>
  
  <p>A value that has a rational type is 8 bytes.</p>
  
  <p>The "value offset" field is 4 bytes.</p>
  
  <p>Therefore, the "value offset" field of an IFD entry with a rational type can only hold an offset (the field can never hold a value).</p>
  
  <p>Is that correct?</p>
