1 Introduction to ImageMagick 2 3 ImageMagick is a software suite to create, edit, compose, or convert 4 bitmap images. It can read and write images in a variety of formats (over 5 200) including PNG, JPEG, JPEG-2000, GIF, TIFF, DPX, EXR, WebP, Postscript, 6 PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, 7 shear and transform images, adjust image colors, apply various special 8 effects, or draw text, lines, polygons, ellipses and Bzier curves. 9 10 The functionality of ImageMagick is typically utilized from the command 11 line or you can use the features from programs written in your favorite 12 language. Choose from these interfaces: G2F (Ada), MagickCore (C), 13 MagickWand (C), ChMagick (Ch), ImageMagickObject (COM+), Magick++ (C++), 14 JMagick (Java), L-Magick (Lisp), Lua, NMagick (Neko/haXe), Magick.NET 15 (.NET), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP 16 (PHP), IMagick (PHP), PythonMagick (Python), RMagick (Ruby), or TclMagick 17 (Tcl/TK). With a language interface, use ImageMagick to modify or create 18 images dynamically and automagically. 19 20 ImageMagick utilizes multiple computational threads to increase performance 21 and can read, process, or write mega-, giga-, or tera-pixel image sizes. 22 23 ImageMagick is free software delivered as a ready-to-run binary distribution 24 or as source code that you may use, copy, modify, and distribute in both open 25 and proprietary applications. It is distributed under the Apache 2.0 license. 26 27 The ImageMagick development process ensures a stable API and ABI. Before 28 each ImageMagick release, we perform a comprehensive security assessment 29 that includes memory error and thread data race detection to prevent 30 security vulnerabilities. 31 32 ImageMagick is available from 33 http://www.imagemagick.org/script/binary-releases.php. It runs on Linux, 34 Windows, Mac Os X, iOS, Android OS, and others. 35 36 The authoritative ImageMagick web site is 37 http://www.imagemagick.org. The authoritative source code repository is 38 http://git.imagemagick.org/repos/ImageMagick/. 39 40 41 Features and Capabilities 42 43 Here are just a few examples of what ImageMagick can do: 44 45 * Format conversion: convert an image from one format to another (e.g. 46 PNG to JPEG). 47 * Transform: resize, rotate, deskew, crop, flip or trim an image. 48 * Transparency: render portions of an image invisible. 49 * Draw: add shapes or text to an image. 50 * Decorate: add a border or frame to an image. 51 * Special effects: blur, sharpen, threshold, or tint an image. 52 * Animation: create a GIF animation sequence from a group of images. 53 * Text & comments: insert descriptive or artistic text in an image. 54 * Image gradients: create a gradual blend of one color whose shape is 55 horizontal, vertical, circular, or ellipical. 56 * Image identification: describe the format and attributes of an image. 57 * Composite: overlap one image over another. 58 * Montage: juxtapose image thumbnails on an image canvas. 59 * Generalized pixel distortion: correct for, or induce image distortions 60 including perspective. 61 * Computer vision: Canny edge detection. 62 * Morphology of shapes: extract features, describe shapes and recognize 63 patterns in images. 64 * Motion picture support: read and write the common image formats used in 65 digital film work. 66 * Image calculator: apply a mathematical expression to an image or image 67 channels. 68 * Connected component labeling: uniquely label connected regions in an 69 image. 70 * Discrete Fourier transform: implements the forward and inverse DFT. 71 * Perceptual hash: maps visually identical images to the same or similar 72 hash-- useful in image retrieval, authentication, indexing, or copy 73 detection as well as digital watermarking. 74 * Complex text layout: bidirectional text support and shaping. 75 * Color management: accurate color management with color profiles or in 76 lieu of-- built-in gamma compression or expansion as demanded by the 77 colorspace. 78 * High dynamic-range images: accurately represent the wide range of 79 intensity levels found in real scenes ranging from the brightest direct 80 sunlight to the deepest darkest shadows. 81 * Encipher or decipher an image: convert ordinary images into 82 unintelligible gibberish and back again. 83 * Virtual pixel support: convenient access to pixels outside the image 84 region. 85 * Large image support: read, process, or write mega-, giga-, or 86 tera-pixel image sizes. 87 * Threads of execution support: ImageMagick is thread safe and most 88 internal algorithms are OpenMP-enabled to take advantage of speed-ups 89 offered by multicore processor chips. 90 * Distributed pixel cache: offload intermediate pixel storage to one or 91 more remote servers. 92 * Heterogeneous distributed processing: certain algorithms are 93 OpenCL-enabled to take advantage of speed-ups offered by executing in 94 concert across heterogeneous platforms consisting of CPUs, GPUs, and 95 other processors. 96 * ImageMagick on the iPhone: convert, edit, or compose images on your 97 iPhone or iPad. 98 99 Examples of ImageMagick Usage shows how to use ImageMagick from the 100 command-line to accomplish any of these tasks and much more. Also, 101 see Fred's ImageMagick Scripts: a plethora of command-line scripts that 102 perform geometric transforms, blurs, sharpens, edging, noise removal, 103 and color manipulations. With Magick.NET, use ImageMagick without having 104 to install ImageMagick on your server or desktop. 105 106
