Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bzier curves."/>

<p class="text-center"><a href="display.html#usage">Example Usage</a>  <a href="display.html#options">Option Summary</a></p>

<p class="lead magick-description">Use the <code>display</code> program to display an image or image sequence on any X server.  See <a href="command-line-processing.html">Command Line Processing</a> for advice on how to structure your <code>display</code> command or see below for example usages of the command.</p>

<h2 class="magick-header"><a id="usage"></a>Example Usage</h2>

<p>We list a few examples of the <code>display</code> command here to illustrate its usefulness and ease of use.  To get started, lets display an image in the JPEG format:</p>

<pre>
display rose.jpg
</pre>

<p>To tile a slate texture onto the root window, use:</p>

<pre>
display -size 1280x1024 -window root slate.png
</pre>

<p>To display a visual image directory of all your JPEG images, use:</p>

<pre>
display 'vid:*.jpg'
</pre>

<p>The display program defaults to the X screen resolution.  To display vecotr formats at their intended size, override the default resolution:</p>

<pre>
display -density 72 drawing.svg
</pre>

<p>You can find additional examples of using <code>display</code> in <a href="http://www.ibm.com/developerworks/library/l-graf/">Graphics from the Command Line</a>.  Further discussion is available in  <a href="https://www.ibm.com/developerworks/library/l-graf2/">More Graphics from the Command Line</a> and <a href="http://www.imagemagick.org/Usage/">Examples of ImageMagick Usage</a>.</p>


<h2 class="magick-header"><a id="options"></a>Option Summary</h2>

<p>The <code>display</code> command recognizes these options.  Click on an option to get more details about how that option works.</p>
