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> 62 63<h2 class="magick-header"><a id="usage"></a>Example Usage</h2> 64 65<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> 66 67<pre> 68display rose.jpg 69</pre> 70 71<p>To tile a slate texture onto the root window, use:</p> 72 73<pre> 74display -size 1280x1024 -window root slate.png 75</pre> 76 77<p>To display a visual image directory of all your JPEG images, use:</p> 78 79<pre> 80display 'vid:*.jpg' 81</pre> 82 83<p>The display program defaults to the X screen resolution. To display vecotr formats at their intended size, override the default resolution:</p> 84 85<pre> 86display -density 72 drawing.svg 87</pre> 88 89<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> 90 91 92<h2 class="magick-header"><a id="options"></a>Option Summary</h2> 93 94<p>The <code>display</code> command recognizes these options.
