Tools Overview</font></h1> | |
<p>This software distribution comes with a small collection of | |
programs for converting non-TIFF format images to TIFF and for | |
manipulating and interrogating the contents of TIFF images. Several | |
of these tools are useful in their own right. Many of them however | |
are more intended to serve as programming examples for using the | |
TIFF library.</p> | |
<h3>Device-dependent Programs</h3> | |
There are two device-dependent programs that serve as simple | |
examples for writing programs to display and save TIFF images. | |
<table border cellpadding="3"> | |
<tr> | |
<td valign="top" width="10%"> | |
<tt><a href="man/tiffgt.1.html">tiffgt</a> </tt></td> | |
<td>Display the contents of one or more TIFF images using OpenGL. | |
The software makes extensive use of the <tt>TIFFRGBAImage</tt> | |
facilities described elsewhere.</td> | |
</tr> | |
<tr> | |
<td valign="top" width="10%"><tt><a href="man/tiffsv.1.html">tiffsv</a></tt></td> | |
<td>A program to save all or part of a screen dump on a Silicon | |
Graphics system. As for <tt>tiffgt</tt> this code, while written to | |
use the IRIS GL, can be easily tailored to other devices.</td> | |
</tr> | |
</table> | |
<h3>Device-independent Programs</h3> | |
The remaining programs should be device-independent: | |

<td>Provides selection of images from within one or more multi-image | |
TIFF files, with orthogonal rotation, mirroring, cropping, and | |
extraction of multiple sections and exporting to one or more files. | |
It extends the functionality of tiffcp to support additional bit | |
depths in strips and tiles and enhances the selection capabilities of | |
tiffsplit. Bilevel images can be inverted and images may be split into | |
segments to fit on multiple /pages/ (standard paper sizes), plus other | |
functions described in the tiffcrop man page</td> | |
