130 <p>For palette images (
<i>PhotometricInterpretation

3),
131 <i>tiffgt
</i> inspects the colormap values and assumes
132 either
16-bit or
8-bit values according to the maximum
133 value. That is, if no colormap entry greater than
255 is
134 found,
<i>tiffgt
</i> assumes the colormap has only
8-bit
135 values; otherwise it assumes
16-bit values. This inspection
136 is done to handle old images written by previous (incorrect)
137 versions of

139 <p><i>tiffgt

143 switches to the first image in the

145 the first file specified on the command line to be
146 displayed. In addition the following keyboard commands are
