 228
 229 <p>We list a few examples of the <kbd>mogrify</kbd> command here to illustrate its usefulness and ease of use.  To get started, lets reduce the size of our
 230 rose:</p>

 240   </a>
 241 </p>
 242
 243 <p>You can resize all your JPEG images in a folder to a maximum dimension of 256x256 with this command:</p>
 244
 245 <p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>mogrify -resize 256x256 *.jpg</span></p>
 246 <p>Finally, we convert all our PNG images to the JPEG format:</p>
 247
 248 <p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>mogrify -format jpg *.png</span></p>
 249 <p>Here image files 1.png, 2.png, etc., are left untouched and files 1.jpg, 2.jpg, etc., are created.  They are copies of their respective PNG images except are stored  in the JPEG image format.</p>
