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> 93 94<h2><a class="anchor" id="usage"></a>Example Usage</h2> 95 96<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> 97 98<pre class="highlight"><code>magick conjure -dimensions 400x400 msl:incantation.msl 99</code></pre> 100 101<p>The MSL script <a href="https://imagemagick.org/source/incantation.msl">incantation.msl</a> used above is here:</p> 102 103<pre class="highlight"><code><?xml version="1.0" encoding="UTF-8"?> 104<image> 105 <read filename="image.gif" /> 106 <get width="base-width" height="base-height" /> 107 <resize geometry="%[dimensions]" /> 108 <get width="resize-width" height="resize-height" /> 109 <print output="Image sized from %[base-width]x%[base-height] to %[resize-width]x%[resize-height].\n" /> 110 <write filename="image.png" /> 111</image> 112</code></pre> 113 114<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> 115 116<pre class="highlight"><code><?xml version="1.0" encoding="UTF-8"?> 117<group> 118 <image id="family"> 119 <read filename="family.gif"/> 120 <resize geometry="300x300"/> 121 </image> 122 <image id="palm-trees"> 123 <read filename="palm-trees.gif"/> 124 <resize geometry="300x100"/> 125 </image> 126 <image> 127 <read filename="beach.jpg"/> 128 <composite image="family" geometry="+30+40"/> 129 <composite image="palm-trees" geometry="+320+90"/> 130 </image> 131 <write filename="family-vacation.png"/> 132</group> 133</code></pre> 134 135<p>Here we display the width in pixels of text for a particular font and pointsize.</p> 136 137<pre class="highlight"><code><?xml version="1.0" encoding="UTF-8"?> 138<image> 139 <query-font-metrics text="ImageMagick" font="helvetica" pointsize="48" /> 140 <print output="Text width is %[msl:font-metrics.width] pixels.\n" /> 141</image> 142</code></pre> 143 144<p>The <code>query-font-metrics</code> tag supports these properties:</p> 145 146<pre class="highlight"><code>msl:font-metrics.pixels_per_em.x 147msl:font-metrics.pixels_per_em.y 148msl:font-metrics.ascent 149msl:font-metrics.descent 150msl:font-metrics.width 151msl:font-metrics.height 152msl:font-metrics.max_advance 153msl:font-metrics.bounds.x1 154msl:font-metrics.bounds.y1 155msl:font-metrics.bounds.x2 156msl:font-metrics.bounds.y2 157msl:font-metrics.origin.x 158msl:font-metrics.origin.y 159</code></pre> 160 161<p>MSL supports most methods and attributes discussed in the <a href="perl-magick.html">Perl API for ImageMagick</a>. 162</p> 163 164<p>In addition, MSL supports the <code>swap</code> element with a single <code>indexes</code> element.</p> 165 166<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>.
