<h1>ALE 0.7.x User Manual</h1>
<h2>Purpose</h2>
<p>This page summarizes program operation and command-line usage for ALE
versions 0.7.0, 0.7.0-patch1, 0.7.1, 0.7.1-patch1, 0.7.1-patch2, and 0.7.2.
Features specific to a particular version are annotated (e.g. [ALE 0.7.1
only]).
<p>Manual pages linked from this section describe <a href="defaults/">default
settings</a>, <a href="file/">file output</a>, <a
href="alignment/">alignment</a>, <a href="rendering/">rendering</a>, <a
href="exclusion/">exclusion regions</a>, <a href="device/">devices</a>, and
<a href="3d/">3D scene reconstruction</a> (Very experimental; ALE 0.7.2 and
later).
<p>For more information on ALE, see the <a
href="http://auricle.dyndns.org/ALE/">ALE Home Page</a>.
<h2>Parameter Meta-syntax</h2>
<table>
<tr>
<td><code>&nbsp;&lt;foo></code></td>
<td>A required parameter called <i>foo</i>.</td>
</tr>
<tr>
<td><code>[&lt;foo>]</code></td>
<td>An optional parameter called <i>foo</i>.
</tr>
<tr>
<td><code>[&lt;foo>]*</code></td>
<td>Zero or more parameters <i>foo</i>.
</tr>
</table>
<h2>Command-line syntax for Image Processing</h2>
<p>The following command-line invocation can be used to process a series of
frames into an output file:
<pre>ale [&lt;option>]* &lt;original-frame> [&lt;supplemental-frame>]* &lt;output-file></pre>
<h3>Option Arguments</h3>
<p>Certain basic modes of operation, emphasizing image quality, speed, or other
rendering characteristics, are now established in the form of <a
href="defaults/">default settings</a>.
<p>Other options are outlined in the manual pages describing <a
href="file/">file output</a>, <a href="rendering/">rendering</a>, <a
href="alignment/">alignment</a>, <a href="exclusion/">exclusion
regions</a>, <a href="device/">devices</a>, and <a href="3d/">3D scene
reconstruction</a> (Very experimental; ALE 0.7.2 and later).
<h3>Image Files</h3>
<p>ALE can be configured at compile time to use one of two different file
handlers. Execute 'ale --version' to determine which file handler is being
used. The table below outlines the supported formats for each file handler.</p>
<table class="inline">
<td>
<table border>
<tr><th>Version Message</th><th>File Types Supported</th></tr>
<tr><td valign=top>
<pre>File handler: ImageMagick</pre>
</td>
<td>
Input and output files can be any of the <a
href="http://imagemagick.sourceforge.net/www/formats.html">formats</a> supported by
ImageMagick.
</td></tr>
<tr><td valign=top>
<pre>File handler: PPM</pre>
<td>
Input files must be PPM, and output files are written as PPM.
</td></tr>
</table>
</table>
<p>Note that many external programs, including ImageMagick's <a
href="http://www.imagemagick.org/">command line utilities</a>, can be used to
convert between PPM and other formats.</p>
<p>See the README included in the source distribution of ALE for more information about
compile-time configuration of file handlers.</p>
<h2>Command-line syntax for Version Information</h2>
<p>The following command-line invocation can be used to print version
information and build options:
<pre>ale --version</pre>
The following is sample output from this invocation:
<pre>
ALE Version: 0.7.2
File handler: ImageMagick
Color data: SINGLE
Coordinate data: SINGLE
DFT: Built-in
Assertions: Disabled
</pre>
<p>The first line of output indicates the version of ALE source code being
used; the remaining lines reflect the build options selected at compile
time.
<p>For more information about build options, see the README file included in
the ALE source distribution.
<h2>Command-line syntax for Help Output</h2>
<p>When invoked with no arguments, or an insufficient number of file arguments,
ALE outputs a help message specifying command-line usage and available help
topics. The following is a sample invocation:
<pre>ale</pre>
<h3>Help Topics</h3>
More information about specific help topics can be obtained with an invocation
of the following form:
<pre>ale &lt;help option&gt;</pre>
Available help options, and their corresponding help topics, are outlined
below:
<pre>
--hu Usage.
--hq Default settings.
--hf Image files.
--he Exclusion regions.
--ha Alignment (not exposure-related).
--hr Rendering (not exposure-related).
--hx Exposure.
--ht Transformation data files.
--hl Filtering (PSFs, rendering chains).
--hd Devices.
--hv Video stream processing (Experimental).
--h3 3D Modeling (Very Experimental). [ALE 0.7.2 and later]
--hz Undocumented options.
--hA Concatenate all help pages. [ALE 0.7.1 and later]
</pre>
