 179
 180 <div class="doc-section">
 181 <p>Use the <code>convert</code> 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="command-line-processing.html">Command Line Processing</a> for advice on how to structure your <code>convert</code> command or see below for example usages of the command.</p>

 183
 184 <h2><a id="usage"></a>Example Usage</h2>
 185 <div class="doc-section">
 186
 187 <p>We list a few examples of the <code>convert</code> command here to illustrate its usefulness and ease of use.  To get started, lets convert an image in the JPEG format to PNG:</p>
 188
 189 <p class="crt"><span class="crtprompt"> $ </span><span class="crtin">convert rose.jpg rose.png</span></p>
 190 <p>Next, we reduce the image size before it is written to the PNG format:</p>
 191
 192 <p class="crt"><span class="crtprompt"> $ </span><span class="crtin">convert rose.jpg -resize 50% rose.png</span></p>
 193 <p class="image">
 194   <a href="../images/rose.jpg">
 195   <img src="../images/rose.jpg" width="70" height="46" alt="rose"></img>
 196   </a>
 197   <img style="margin-top:13px; margin-bottom:13px;" src="../images/right.gif" width="20" height="20" alt="==&gt;"></img>
 198   <a href="../images/rose.png">
 199   <img style="margin-top:11px; margin-bottom:12px;" src="../images/rose.png" width="35" height="23" alt="rose"></img>
 200   </a>
 201 </p>
 202
 203 <p>You can combine multiple image-processing operations to produce complex results:</p>
 204
 205 <p class="crt"><span class="crtprompt"> $ </span><span class="crtin">convert -size 320x85 canvas:none -font Bookman-DemiItalic -pointsize 72 \ <br></br>
 206 -draw "text 25,60 'Magick'" -channel RGBA -blur 0x6 -fill darkred -stroke magenta \ <br></br>
 207 -draw "text 20,55 'Magick'" fuzzy-magick.png</span></p>
 208 <p class="image">
 209   <a href="../images/fuzzy-magick.png"><img src="../images/fuzzy-magick.png" width="320" height="85" alt="fuzzy-magick"></img></a>
 210 </p>
 211
 212 <p>or here we resize an image with improved quality:</p>
 213
 214 <p class="crt"><span class="crtprompt"> $ </span><span class="crtin">convert input.png -colorspace RGB +sigmoidal-contrast 11.6933 \ <br></br>
 215   -define filter:filter=Sinc -define filter:window=Jinc -define filter:lobes=3      \ <br></br>
 216   -resize 400% -sigmoidal-contrast 11.6933 -colorspace sRGB output.png</span></p>
 217 <p>You can find additional examples of using <code>convert</code> in <a href="http://www.imagemagick.org/Usage/">Examples of ImageMagick Usage</a>.</p>
