19 <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."/>

159<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</div>
161
162<h2><a name="usage"></a>Example Usage</h2>
163<div class="doc-section">
164
165<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>
166
167<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>convert rose.jpg rose.png</span></p>
168<p>Next, we reduce the image size before it is written to the PNG format:</p>
169
170<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>convert rose.jpg -resize 50% rose.png</span></p>
171<p class="image">
172 <a href="../images/rose.jpg">
173 <img src="../images/rose.jpg" width="70" height="46" alt="rose" />
174 </a>
175 <img style="margin-top:13px; margin-bottom:13px;" src="../images/right.gif" width="20" height="20" alt="==>" />
176 <a href="../images/rose.png">
177 <img style="margin-top:11px; margin-bottom:12px;" src="../images/rose.png" width="35" height="23" alt="rose" />
178 </a>
179</p>
180
181<p>You can combine multiple image-processing operations to produce complex results:</p>
182
183<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>convert -size 320x85 xc:transparent -font Bookman-DemiItalic -pointsize 72 \ <br/>

cristy3ed852e2009-09-05 21:47:34 +0000[diff] [blame]185-draw "text 20,55 'Magick'" fuzzy-magick.png</span></p>
