 248 <p>Use the <kbd>magick</kbd> program to convert between image formats as well as resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more.   See <a href="../www/command-line-processing.html">Command Line Processing</a> for advice on how to structure your <kbd>magick</kbd> command or see below for example usages of the command.</p>

 252 <div class="doc-section">
 253
 254 <p>We list a few examples of the <kbd>magick</kbd> command here to illustrate its usefulness and ease of use.  To get started, lets convert an image in the JPEG format to PNG:</p>
 255
 256 <p class='crt'><span class="crtprompt"> $ </span><span class='crtin'>magick rose.jpg rose.png</span></p>
 257 <p>Next, we reduce the image size before it is written to the PNG format:</p>
 258
 259 <p class='crt'><span class="crtprompt"> $ </span><span class='crtin'>magick rose.jpg -resize 50% rose.png</span></p>
 260 <p class="image">

 264   <img style="margin-top:13px; margin-bottom:13px;" src="../images/right.gif" width="20" height="20" alt="==>" />

 267   </a>
 268 </p>
 269
 270 <p>You can combine multiple image-processing operations to produce complex results:</p>
 271
 272 <p class='crt'><span class="crtprompt"> $ </span><span class='crtin'>magick -size 320x85 canvas:none -font Bookman-DemiItalic -pointsize 72 \ <br/>
