<span class="c1"># TIFF file handling</span>
<span class="c1">#</span>
<span class="c1"># TIFF is a flexible, if somewhat aged, image file format originally</span>
<span class="c1"># defined by Aldus. Although TIFF supports a wide variety of pixel</span>
<span class="c1"># layouts and compression methods, the name doesn't really stand for</span>
<span class="c1"># "thousands of incompatible file formats," it just feels that way.</span>
<span class="c1">#</span>
<span class="c1"># To read TIFF data from a stream, the stream must be seekable. For</span>
<span class="c1"># progressive decoding, make sure to use TIFF files where the tag</span>
<span class="c1"># directory is placed first in the file.</span>
<span class="c1">#</span>
