13 <meta name="Description" content="ImageMagick® is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (about 100) including GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and DPX. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you can freely use, copy, modify, and distribute. Its license is compatible with the GPL. It runs on all major operating systems. The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. Choose from these interfaces: MagickCore (C), MagickWand (C), ChMagick (Ch), Magick++ (C++), JMagick (Java), L-Magick (Lisp), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP (PHP), PythonMagick (Python), RMagick (Ruby), or TclMagick (Tcl/TK). With a language interface, use ImageMagick to modify or create images automagically and dynamically."/>

177<p>Use the <kbd>mogrify</kbd> program to resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more. This tool is similiar to <a href="../www/convert.html">convert</a> except that the original image file is overwritten (unless you change the file suffix with the <a href="../www/command-line-options.html#format">-format</a> option) with any changes you request. See <a href="../www/command-line-processing.html">Command Line Processing</a> for advice on how to structure your <kbd>mogrify</kbd> command or see below for sample usages of the command.</p>

179
180<h2><a name="usage"></a>Example Usage</h2>
181<div class="doc-section">
182
183<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
184rose:</p>
185
186<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>mogrify -resize 50% rose.jpg</span></p>
187<p class="image">
188 <a href="../images/rose.jpg">
189 <img src="../images/rose.jpg" width="70" height="46" alt="rose" />
190 </a>
191 <img style="margin-top:13px; margin-bottom:13px;" src="../images/right.gif" width="20" height="20" alt="==>" />
192 <a href="../images/rose.png">
193 <img style="margin-top:12px; margin-bottom: 11px;" src="../images/rose.png" width="35" height="23" alt="rose" />
194 </a>
195</p>
196
197<p>You can resize all your JPEG images in a folder to a maximum dimension of 256x256 with this command:</p>
198
199<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>mogrify -resize 256x256 *.jpg</span></p>
200<p>Finally, we convert all our PNG images to the JPEG format:</p>
201
202<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>mogrify -format jpg *.png</span></p>
203<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>
204
205
206<p>You can find additional examples of using <kbd>mogrify</kbd> in <a href="http://www-106.ibm.com/developerworks/library/l-graf/?ca=dnt-428">Graphics from the Command Line</a>. Further discussion is available in <a href="http://www-106.ibm.com/developerworks/library/l-graf2/?ca=dgr-lnxw15GraphicsLine">More Graphics from the Command Line</a> and <a href="http://www.imagemagick.org/Usage/">Examples of ImageMagick Usage</a>.</p>
