240 <h1>ImageMagick Conjure Command-line Tool</h1>
241 <p class="navigation-index">[<a href="conjure.html#usage">Example Usage</a> • <a href="conjure.html#options">Option Summary</a>]</p>
243 <div class="doc-section">
244 <p>The <kbd>conjure</kbd> program gives you the ability to perform custom image processing tasks from a script written in the Magick Scripting Language (MSL). 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 <kbd>conjure</kbd> command or see below for example usages of the command.</p>
247 <h2><a id="usage"></a>Example Usage</h2>
248 <div class="doc-section">
250 <p>We list a few examples of the <kbd>conjure</kbd> command here to illustrate its usefulness and ease of use. To get started, here is simple <kbd>conjure</kbd> command:</p>
252 <p class='crt'><span class="crtprompt"> $ </span><span class='crtin'>conjure -dimensions 400x400 incantation.msl</span></p>
253 <p>The MSL script <a href="../www/source/incantation.msl">incantation.msl</a> used above is here:</p>
256 <?xml version="1.0" encoding="UTF-8"?>
257 <image size="400x400">
258 <read filename="image.gif" />
259 <get width="base-width" height="base-height" />
260 <resize geometry="%[dimensions]" />
261 <get width="width" height="height" />
262 <print output="Image sized from %[base-width]x%[base-height] to %[width]x%[height].\n" />
263 <write filename="image.png" />
267 <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>
270 <?xml version="1.0" encoding="UTF-8"?>
272 <image id="family">
273 <read filename="family.gif"/>
274 <resize geometry="300x300"/>
276 <image id="palm-trees">
277 <read filename="palm-trees.gif"/>
278 <resize geometry="300x100"/>
281 <read filename="beach.jpg"/>
282 <composite image="family" geometry="+30+40"/>
283 <composite image="palm-trees" geometry="+320+90"/>
285 <write filename="family-vacation.png"/>
289 <p>Here we display the width in pixels of text for a particular font and pointsize.</p>
292 <?xml version="1.0" encoding="UTF-8"?>
294 <query-font-metrics text="ImageMagick" font="helvetica" pointsize="48" />
295 <print output="Text width is %[msl:font-metrics.width] pixels.\n" />
299 <p>The <kbd>query-font-metrics</kbd> tag supports these properties:</p>
302 msl:font-metrics.pixels_per_em.x
303 msl:font-metrics.pixels_per_em.y
304 msl:font-metrics.ascent
305 msl:font-metrics.descent
306 msl:font-metrics.width
307 msl:font-metrics.height
308 msl:font-metrics.max_advance
309 msl:font-metrics.bounds.x1
310 msl:font-metrics.bounds.y1
311 msl:font-metrics.bounds.x2
312 msl:font-metrics.bounds.y2
313 msl:font-metrics.origin.x
314 msl:font-metrics.origin.y
317 <p>MSL supports most methods and attributes discussed in the <a href="perl-magick.html">Perl API for ImageMagick</a>.
320 <p>In addition, MSL supports the <kbd>swap</kbd> element with a single <kbd>indexes</kbd> element.</p>
322 <p>You can find additional examples of using <kbd>conjure</kbd> in <a href="http://www-106.ibm.com/developerworks/library/l-graf/?ca=dnt-428">Graphics from the Command Line</a>. Further discussion is available in <a href="http://www-106.ibm.com/developerworks/library/l-graf2/?ca=dgr-lnxw15GraphicsLine">More Graphics from the Command Line</a> and <a href="http://www.imagemagick.org/Usage/">Examples of ImageMagick Usage</a>.</p>
