 155 <p>Use the <kbd>convert</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>convert</kbd> command or see below for example usages of the command.</p>

 160
 161 <p>We list a few examples of the <kbd>convert</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>
 162
 163 <p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>convert rose.jpg rose.png</span></p>
 164 <p>Next, we reduce the image size before it is written to the PNG format:</p>
 165
 166 <p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>convert rose.jpg -resize 50% rose.png</span></p>

 174   </a>
 175 </p>
 176
 177 <p>You can combine multiple image-processing operations to produce complex results:</p>
 178
 179 <p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>convert -size 320x85 xc:transparent -font Bookman-DemiItalic -pointsize 72 \ <br/>
