Use ImageMagick<sup><a href="http://tarr.uspto.gov/servlet/tarr?regser=serial&entry=78333969">®</a></sup> to create, edit, compose, or convert bitmap images. It can read and write images in a variety of <a href="www/formats.html">formats</a> (over 200) including PNG, JPEG, GIF, HEIC, TIFF, <a href="www/motion-picture.html">DPX</a>, <a href="www/high-dynamic-range.html">EXR</a>, WebP, Postscript, PDF, and SVG. ImageMagick can resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.</p>
|
|
|
|
<p>ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you may use, copy, modify, and distribute in both open and proprietary applications. It is distributed under a derived Apache 2.0 <a href="www/license.html">license</a>.</p>
|
|
|
|
<p>ImageMagick utilizes multiple computational threads to increase performance and can read, process, or write mega-, giga-, or tera-pixel image sizes.</p>
|
|
|
|
<p>The current release is ImageMagick <a href="www/download.html">6.9.11-59</a>. It runs on <a href="www/download.html#unix">Linux</a>, <a href="www/download.html#windows">Windows</a>, <a href="www/download.html#macosx">Mac Os X</a>, <a href="www/download.html#iOS">iOS</a>, <a href="https://github.com/cherryleafroad/Android-ImageMagick7">Android</a> OS, and others.</p>

|
|
|
<p>The design of ImageMagick is an evolutionary process, with the design and implementation efforts serving to influence and guide further progress in the other. With <a href="./">ImageMagick version 7</a>, we aim to improve the design based on lessons learned from the version 6 implementation.</p>

<p><a href="https://legacy.imagemagick.org/Usage/" target="_blank">Examples of ImageMagick Usage</a> shows how to use ImageMagick from the <a href="www/command-line-processing.html">command-line</a> to accomplish any of these tasks and much more. Also, see <a href="http://www.fmwconcepts.com/imagemagick/" target="_blank">Fred's ImageMagick Scripts</a>: a plethora of command-line scripts that perform geometric transforms, blurs, sharpens, edging, noise removal, and color manipulations. With <a href="https://github.com/dlemstra/Magick.NET">Magick.NET</a>, use ImageMagick without having to install ImageMagick on your server or desktop. Finally, see <a href="http://im.snibgo.com/">Snibgo's ImageMagick Cookbook</a> for Windows-based ImageMagick scripting.</p>
