This tool is similar to <a href="convert.php">convert</a> except that the original image file is overwritten (unless you change the file suffix with the <a href="command-line-options.php#format">-format</a> option) with any changes you request. See <a href="command-line-processing.php">Command Line Processing</a> for advice on how to structure your <code>mogrify</code> command or see below for sample usages of the command.</p> 58 59<h2 class="magick-header"><a id="usage"></a>Example Usage</h2> 60 61<p>We list a few examples of the <code>mogrify</code> command here to illustrate its usefulness and ease of use. To get started, let's reduce the size of our 62rose:</p> 63 64<pre> 65mogrify -resize 50% rose.jpg 66</pre> 67 68<ul> 69 <a href="../image/rose.jpg"> 70 <img src="../image/rose.jpg" width="70" height="46" alt="rose" /> 71 </a> 72 <img style="margin-top:13px; margin-bottom:13px;" src="../image/right.gif" width="20" height="20" alt="==>" /> 73 <a href="../image/rose.png"> 74 <img style="margin-top:12px; margin-bottom: 11px;" src="../image/rose.png" width="35" height="23" alt="rose" /> 75 </a> 76</ul> 77 78<p>You can resize all your JPEG images in a folder to a maximum dimension of 256x256 with this command:</p> 79 80<pre> 81mogrify -resize 256x256 *.jpg 82</pre> 83 84<p>Finally, we convert all our PNG images in a folder to the JPEG format:</p> 85 86<pre> 87mogrify -format jpg *.png 88</pre> 89 90<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> 91 92 93<p>You can find additional examples of using <code>mogrify</code> in <a href="http://www.ibm.com/developerworks/library/l-graf/?ca=dnt-428">Graphics from the Command Line</a>.
