Several 15of these tools are useful in their own right. Many of them however 16are more intended to serve as programming examples for using the 17TIFF library.</p> 18<h3>Device-dependent Programs</h3> 19There are two device-dependent programs that serve as simple 20examples for writing programs to display and save TIFF images. 21<table border cellpadding="3"> 22<tr> 23<td valign="top" width="10%"> 24<tt><a href="man/tiffgt.1.html">tiffgt</a> </tt></td> 25<td>Display the contents of one or more TIFF images using OpenGL. 26The software makes extensive use of the <tt>TIFFRGBAImage</tt> 27facilities described elsewhere.</td> 28</tr> 29</table> 30<h3>Device-independent Programs</h3> 31The remaining programs should be device-independent: 32<table border cellpadding="3"> 33<td valign="top" width="10%"><tt><a href="man/fax2ps.1.html">fax2ps</a></tt></td> 34<td>Convert a Group 3- or Group 4- compressed TIFF to PostScript 35that is significantly more compressed than is generated by 36<tt>tiff2ps</tt> (unless <tt>tiff2ps</tt> writes PS Level II)</td> 37</tr> 38<tr> 39<td valign="top" width="10%"><tt><a href="man/fax2tiff.1.html">fax2tiff</a></tt></td> 40<td>Convert raw Group 3 or Group 4 facsimile data to TIFF</td> 41</tr> 42<td valign="top" width="10%"><tt><a href="man/pal2rgb.1.html">pal2rgb</a></tt></td> 43<td>Convert a Palette-style image to a full color RGB image by 44applying the colormap</td> 45</tr> 46<tr> 47<td valign="top" width="10%"><tt><a href="man/ppm2tiff.1.html">ppm2tiff</a></tt></td> 48<td>A quick hack that converts 8-bit PPM format images to TIFF</td> 49</tr> 50<td valign="top" width="10%"><tt><a href="man/raw2tiff.1.html">raw2tiff</a></tt></td> 51<td>Create a TIFF file from raw data</td> 52</tr> 53<tr> 54<td valign="top" width="10%"><tt><a href="man/rgb2ycbcr.1.html">rgb2ycbcr</a></tt></td> 55<td>Convert an RGB, grayscale, or bilevel TIFF image to a YCbCr 56TIFF image; it's mainly provided for testing</td> 57</tr> 58<tr> 59<td valign="top" width="10%"><tt><a href="man/thumbnail.1.html">thumbnail</a></tt></tt></td> 60<td>Copy a bilevel TIFF to one that includes 8-bit greyscale 61"thumbnail images" for each page; it is provided as an example of 62how one might use the <tt>SubIFD</tt> tag (and the library support 63for it)</td> 64</tr> 65<tr> 66<td valign="top" width="10%"><tt><a href="man/tiff2bw.1.html">tiff2bw</a></tt></td> 67<td>A simple program to convert a color image to grayscale</td> 68</tr> 69<tr> 70<td valign="top" width="10%"><tt><a href="man/tiff2pdf.1.html">tiff2pdf</a></tt></td> 71<td>Convert TIFF images to PDF</td> 72</tr> 73<tr> 74<td valign="top" width="10%"><tt><a href="man/tiff2ps.1.html">tiff2ps</a></tt></td> 75<td>Convert TIFF images to PostScript</td> 76</tr> 77<tr> 78<td valign="top" width="10%"><tt><a href="man/tiff2rgba.1.html">tiff2rgba</a></tt></td> 79<td>Convert a TIFF image to RGBA color space</td> 80</tr> 81<tr> 82<td valign="top" width="10%"><tt><a href="man/tiffcmp.1.html">tiffcmp</a></tt></td> 83<td>Compare the contents of two TIFF files (it does not check all 84the directory information, but does check all the data)</td> 85</tr> 86<tr> 87<td valign="top" width="10%"><tt><a href="man/tiffcp.1.html">tiffcp</a></tt></td> 88<td>Copy, concatenate, and convert TIFF images (e.g. switching from 89Compression=5 to Compression=1)</td> 90</tr> 91<tr> 92<td valign="top" width="10%"><tt><a href="man/tiffcrop.1.html">tiffcrop</a></tt></td> 93<td>Provides selection of images from within one or more multi-image 94TIFF files, with orthogonal rotation, mirroring, cropping, and 95extraction of multiple sections and exporting to one or more files. 96It extends the functionality of tiffcp to support additional bit 97depths in strips and tiles and enhances the selection capabilities of 98tiffsplit.
