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."/> <meta name="Rating" content="GENERAL"/> <meta name="Robots" content="INDEX, FOLLOW"/> <meta name="Generator" content="ImageMagick Studio LLC"/> <meta name="Author" content="ImageMagick Studio LLC"/> <meta name="Revisit-after" content="2 DAYS"/> <meta name="Resource-type" content="document"/> <meta name="Copyright" content="Copyright (c) 1999-2009 ImageMagick Studio LLC"/> <meta name="Distribution" content="Global"/> <link rel="shortcut icon" href="../images/wand.ico" type="images/vnd.microsoft.icon"/> </head> <body id="www-imagemagick-org"> <div class="titlebar"> <a href="../index.html"> <img src="../images/script.png" alt="[ImageMagick]" style="width: 350px; height: 60px; margin: 28px auto; float: left;" /></a> <a href="http://www.networkredux.com"> <img src="../images/networkredux.png" alt="[sponsor]" style="margin: 45px auto; border: 0px; float: left;" /></a> <a href="http://www.imagemagick.org/discourse-server/"> <img src="../images/logo.jpg" alt="" style="width: 114px; height: 118px; border: 0px; float: right;" /></a> <a href="../index.html"> <img src="../images/sprite.jpg" alt="" style="width: 114px; height: 118px; border: 0px; float: right;" /></a> </div> <div class="eastbar"> <div class="menu"> <a href="../index.html">About ImageMagick</a> </div> <div class="sep"></div> <div class="menu"> <a href="../www/command-line-tools.html">Command-line Tools</a> </div> <div class="sub"> <a href="../www/command-line-processing.html">Processing</a> </div> <div class="sub"> <a href="../www/command-line-options.html">Options</a> </div> <div class="sub"> <a href="http://www.imagemagick.org/Usage/">Usage</a> </div> <div class="menu"> <a href="../www/api.html">Program Interfaces</a> </div> <div class="sub"> <a href="../www/magick-wand.html">MagickWand</a> </div> <div class="sub"> <a href="../www/magick-core.html">MagickCore</a> </div> <div class="sub"> <a href="../www/perl-magick.html">PerlMagick</a> </div> <div class="sub"> <a href="../Magick++/">Magick++</a> </div> <div class="menu"> <a href="../www/architecture.html">Architecture</a> </div> <div class="sep"></div> <div class="menu"> <a href="../www/install-source.html">Install from Source</a> </div> <div class="sub"> <a href="../www/install-source.html#unix">Unix</a> </div> <div class="sub"> <a href="../www/install-source.html#windows">Windows</a> </div> <div class="menu"> <a href="../www/binary-releases.html">Binary Releases</a> </div> <div class="sub"> <a href="../www/binary-releases.html#unix">Unix</a> </div> <div class="sub"> <a href="../www/binary-releases.html#macosx">Mac OS X</a> </div> <div class="sub"> <a href="../www/binary-releases.html#windows">Windows</a> </div> <div class="menu"> <a href="../www/resources.html">Resources</a> </div> <div class="sep"></div> <div class="menu"> <a href="../www/download.html">Download</a> </div> <div class="sep"></div> <div class="menu"> <a href="http://www.imagemagick.org/script/search.php">Search</a> </div><div class="sep"></div> <div class="menu"> <a href="../www/sitemap.html">Site Map</a> </div> <div class="sub"> <a href="../www/links.html">Links</a> </div> <div class="sep"></div> <div class="menu"> <a href="../www/sponsors.html">Sponsors:</a> <div class="sponsbox"> <div class="sponsor"> <a href="http://www.f1online.de">Bildagentur<br />F1 ONLINE</a><!-- 200909010480 --> </div> <div class="sponsor"> <a href="http://www.who-sells-it.com/">Free Catalogs</a><!-- 201002010000 --> </div> <div class="sponsor"> <a href="http://www.online-kredit-index.de">Kredit</a><!-- 200905010120 --> </div> <div class="sponsor"> <a href="http://www.posters555.com">Poster</a><!-- 200903010800 --> </div> </div> </div> </div> <div class="main"> <p class="navigation-index">[<a href="#usage">Example Usage</a> • <a href="#options">Option Summary</a>]</p> <p>Use the <kbd>display</kbd> program to display an image or image sequence on any X server.
