  70 <p><big>The value of <i>strip</i> is a &lsquo;&lsquo;raw
  71 strip number.&rsquo;&rsquo; That is, the caller must take
  72 into account whether or not the data are organized in
  73 separate planes (<i>PlanarConfiguration</i>=2). To read a
  74 full strip of data the data buffer should typically be at
  75 least as large as the number returned by
  76 <b>TIFFStripSize</b>(3TIFF). If the -1 passed in <i>size</i>
  77 parameter, the whole strip will be read. You should be sure
  78 you have enough space allocated for the buffer.</big></p>
  79 <!-- INDENTATION -->
  80 <p><big>The library attempts to hide bit- and byte-ordering
  81 differences between the image and the native machine by
  82 converting data to the native machine order. Bit reversal is
  83 done if the <i>FillOrder</i> tag is opposite to the native
  84 machine bit order. 16- and 32-bit samples are automatically
  85 byte-swapped if the file was written with a byte order
  86 opposite to the native machine byte order,</big></p>
