52<p><i>thumbnail</i> is a program written to show how one
53might use the SubIFD tag (#330) to store thumbnail images.
54<i>thumbnail</i> copies a <small>TIFF</small> Class F
55facsimile file to the output file and for each image an
568-bit greyscale <i>thumbnail sketch</i>. The output file
57contains the thumbnail image with the associated
58full-resolution page linked below with the SubIFD tag.</p>
59<!-- INDENTATION -->
60<p>By default, thumbnail images are 216 pixels wide by 274
61pixels high. Pixels are calculated by sampling and filtering
62the input image with each pixel value passed through a
63contrast curve.</p>
