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).

You can use the language to draw from the command line, from an MVG file, from an <a href="http://www.w3.org/TR/SVG/" target="1246037877">SVG -- Scalable Vector Graphics</a> file or from one of the ImageMagick <a href="../www/api.html">program interfaces</a>. Use this command, for example, to render an arc:</p> <pre class="text"> convert -size 100x60 xc:skyblue -fill white -stroke black \ -draw "path 'M 30,40 A 30,20 20 0,0 70,20 A 30,20 20 1,0 30,40 Z '" \ arc.png </pre> <p>and here is the results:</p> <p class="image"> <a href="../images/arc.png"><img src="../images/arc.png" width="100" height="60" align="middle" alt="arc" /></a> </p> <p>When the drawing gets sufficiently complex, we recommend you assemble the graphic primitives into a MVG file.

ImageMagick automatically converts SVG to MVG and renders your image, for example, we render <a href="../www/source/piechart.svg">piechart.svg</a> with this command: <pre class="text"> convert piechart.svg piechart.jpg </pre> <p>to produce the same pie chart we created with the the MVG language.</p> <p>Drawing is available from many of the ImageMagick <a href="../www/api.html">program interfaces</a> as well. ImageMagick converts the drawing API calls to MVG and renders it.
