<p><i>tiffgt</i> displays one or more images stored using

the Tag Image File Format, Revision 6.0. Each image is

placed in a fixed size window that the user must position on

defaults). If the display has fewer than 24 bitplanes, or if

the image does not warrant full color, then

|

<!-- INDENTATION -->

|
<p>For palette images (<i>PhotomatricInterpretation</i>=3),
|
|
<i>tiffgt</i> inspects the colormap values and assumes
|
|
either 16-bit or 8-bit values according to the maximum
|
|
value. That is, if no colormap entry greater than 255 is
|
|
found, <i>tiffgt</i> assumes the colormap has only 8-bit
|
|
values; otherwise it assumes 16-bit values. This inspection
|
|
is done to handle old images written by previous (incorrect)
|
|
versions of <i>libtiff</i>.</p>
|
|
<!-- INDENTATION -->
|
|
<p><i>tiffgt</i> can be used to display multiple images
|
|
one-at-a-time. The left mouse button switches the display to
|
|
the first image in the <i>next</i> file in the list of files
|
|
specified on the command line. The right mouse button
|
|
switches to the first image in the <i>previous</i> file in
|
|
the list. The middle mouse button causes the first image in
|
|
the first file specified on the command line to be
|
|
displayed. In addition the following keyboard commands are

|
recognized:</p>
