17 <section><title>Purpose (foobar)</title>
19 <para>This page summarizes program operation and command-line usage for ALE
20 versions 0.8.0 through 0.8.4. Features specific to a particular version
21 are annotated (e.g. [ALE 0.8.1 and later]).</para>
23 <para>Manual pages linked from this section describe <a href="defaults/">default
24 settings</a>, <a href="file/">file output</a>, <a
25 href="alignment/">alignment</a>, <a href="rendering/">rendering</a>, <a
26 href="exclusion/">exclusion regions</a>, <a href="cp/">control points</a>, <a href="ui/">user interfaces</a>, <a
27 href="device/">devices</a>, and <a href="3d/">3D scene reconstruction</a>.</para>
29 <para>For more information on ALE, see the <a
30 href="http://auricle.dyndns.org/ALE/">ALE Home Page</a>.</para>
33 <section><title>Parameter Meta-syntax</title>
37 <td><code><foo></code></td>
38 <td>A required parameter called <i>foo</i>.</td>
41 <td><code>[<foo>]</code></td>
42 <td>An optional parameter called <i>foo</i>.</td>
45 <td><code>[<foo>]*</code></td>
46 <td>Zero or more parameters <i>foo</i>.</td>
51 <section><title>Command-line syntax for Image Processing</title>
53 <para>The following command-line invocation can be used to process a series of
54 frames into an output file:</para>
56 <pre>ale [<option>]* <original-frame> [<supplemental-frame>]* <output-file></pre>
58 <h3>Option Arguments</h3>
60 <para>Certain basic modes of operation, emphasizing image quality, speed, or other
61 rendering characteristics, are now established in the form of <a
62 href="defaults/">default settings</a>.</para>
64 <para>Other options are outlined in the manual pages describing <a
65 href="file/">file output</a>, <a href="rendering/">rendering</a>, <a
66 href="alignment/">alignment</a>, <a href="exclusion/">exclusion
67 regions</a>, <a href="device/">devices</a>, <a href="ui/">user interfaces</a>,
68 and <a href="3d/">3D scene reconstruction</a>.</para>
72 <para>ALE can be configured at compile time to use one of two different file
73 handlers. Execute 'ale --version' to determine which file handler is being
74 used. The table below outlines the supported formats for each file handler.</para>
76 <table class="inline">
79 <tr><th>Version Message</th><th>File Types Supported</th></tr>
81 <pre>File handler: ImageMagick</pre>
85 Input and output files can be any of the <a
86 href="http://imagemagick.sourceforge.net/www/formats.html">formats</a> supported by
91 <pre>File handler: PPM</pre>
93 Input files must be PPM, and output files are written as PPM.
99 <para>Note that many external programs, including ImageMagick's <a
100 href="http://www.imagemagick.org/">command line utilities</a>, can be used to
101 convert between PPM and other formats.</para>
103 <para>See the README included in the source distribution of ALE for more information about
104 compile-time configuration of file handlers.</para>
108 <title>Command-line syntax for Version Information</title>
110 <para>The following command-line invocation can be used to print version
111 information and build options:</para>
113 <pre>ale --version</pre>
115 <para>The following is sample output from this invocation:</para>
119 File handler: ImageMagick
121 Coordinate data: SINGLE
124 Optimizations: Enabled
127 <para>The first line of output indicates the version of ALE source code being
128 used; the remaining lines reflect the build options selected at compile
131 <para>For more information about build options, see the README file included in
132 the ALE source distribution.</para>
136 <title>Command-line syntax for Help Output</title>
138 <para>When invoked with no arguments, or an insufficient number of file arguments,
139 ALE outputs a help message specifying command-line usage and available help
140 topics. The following is a sample invocation:</para>
146 <para>More information about specific help topics can be obtained with an invocation
147 of the following form:</para>
149 <pre>ale <help option></pre>
151 <para>Available help options, and their corresponding help topics, are outlined
156 --hq Default settings.
158 --he Exclusion regions.
159 --ha Alignment (not exposure-related).
160 --hr Rendering (not exposure-related).
162 --ht Transformation data files.
163 --hc Control points. [0.8.1 and later]
164 --hl Filtering (PSFs, rendering chains).
166 --hi User Interfaces.
167 --hv Video stream processing (Experimental).
169 --hz Undocumented options.
170 --hA Concatenate all help pages.
