188<p>We list a few examples of the <kbd>display</kbd> command here to illustrate its usefulness and ease of use. To get started, lets display an image in the JPEG format:</p>
189
190<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>display rose.jpg</span></p>
191<p>To tile a slate texture onto the root window, use:</p>
192
193<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>display -size 1280x1024 -window root slate.png</span></p>
194<p>To display a visual image directory of all your JPEG images, use:</p>
195
196<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>display 'vid:*.jpg'</span></p>
197<p>You can find additional examples of using <kbd>display</kbd> in <a href="http://www-106.ibm.com/developerworks/library/l-graf/?ca=dnt-428">Graphics from the Command Line</a>.
