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> 97 98<h2><a class="anchor" id="usage"></a>Example Usage</h2> 99 100<p>We list a few examples of the <code>conjure</code> command here to illustrate its usefulness and ease of use. To get started, here is simple <code>conjure</code> command:</p> 101 102<pre class="highlight"><code>magick conjure -dimensions 400x400 msl:incantation.msl 103</code></pre> 104 105<p>The MSL script <a href="https://imagemagick.org/source/incantation.msl">incantation.msl</a> used above is here:</p> 106 107<pre class="highlight"><code><?xml version="1.0" encoding="UTF-8"?> 108<image> 109 <read filename="image.gif" /> 110 <get width="base-width" height="base-height" /> 111 <resize geometry="%[dimensions]" /> 112 <get width="resize-width" height="resize-height" /> 113 <print output="Image sized from %[base-width]x%[base-height] to %[resize-width]x%[resize-height].\n" /> 114 <write filename="image.png" /> 115</image> 116</code></pre> 117 118<p>In this example, a family stayed home for their vacation but as far as their friends are concerned they went to a beautiful beach in the Caribbean:</p> 119 120<pre class="highlight"><code><?xml version="1.0" encoding="UTF-8"?> 121<group> 122 <image id="family"> 123 <read filename="family.gif"/> 124 <resize geometry="300x300"/> 125 </image> 126 <image id="palm-trees"> 127 <read filename="palm-trees.gif"/> 128 <resize geometry="300x100"/> 129 </image> 130 <image> 131 <read filename="beach.jpg"/> 132 <composite image="family" geometry="+30+40"/> 133 <composite image="palm-trees" geometry="+320+90"/> 134 </image> 135 <write filename="family-vacation.png"/> 136</group> 137</code></pre> 138 139<p>Here we display the width in pixels of text for a particular font and pointsize.</p> 140 141<pre class="highlight"><code><?xml version="1.0" encoding="UTF-8"?> 142<image> 143 <query-font-metrics text="ImageMagick" font="helvetica" pointsize="48" /> 144 <print output="Text width is %[msl:font-metrics.width] pixels.\n" /> 145</image> 146</code></pre> 147 148<p>The <code>query-font-metrics</code> tag supports these properties:</p> 149 150<pre class="highlight"><code>msl:font-metrics.pixels_per_em.x 151msl:font-metrics.pixels_per_em.y 152msl:font-metrics.ascent 153msl:font-metrics.descent 154msl:font-metrics.width 155msl:font-metrics.height 156msl:font-metrics.max_advance 157msl:font-metrics.bounds.x1 158msl:font-metrics.bounds.y1 159msl:font-metrics.bounds.x2 160msl:font-metrics.bounds.y2 161msl:font-metrics.origin.x 162msl:font-metrics.origin.y 163</code></pre> 164 165<p>MSL supports most methods and attributes discussed in the <a href="../www/perl-magick.html">Perl API for ImageMagick</a>. 166</p> 167 168<p>In addition, MSL supports the <code>swap</code> element with a single <code>indexes</code> element.</p> 169 170<p>You can find additional examples of using <code>conjure</code> in <a href="http://www.ibm.com/developerworks/library/l-graf/?ca=dnt-428">Graphics from the Command Line</a>.
