MSL is XML-based and consists of action statements with attributes. Actions include reading an image, processing an image, getting attributes from an image, writing an image, and more. An attribute is a key/value pair that modifies the behavior of an action. See <a href="command-line-processing.html">Command Line Processing</a> for advice on how to structure your <code>conjure</code> command or see below for example usages of the command.</p> 87 88 <h2><a class="anchor" id="usage"></a>Example Usage</h2> 89 90 <p>We list a few examples of the <code>conjure</code> command here to illustrate its usefulness and ease of use.
