6 #Introduction to ImageMagick
8 ImageMagick® is a software suite to create, edit, compose, or convert
9 bitmap images. It can read and write images in a variety of formats (over
10 200) including PNG, JPEG, JPEG-2000, GIF, TIFF, DPX, EXR, WebP, Postscript,
11 PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort,
12 shear and transform images, adjust image colors, apply various special
13 effects, or draw text, lines, polygons, ellipses and Bézier curves.
15 The functionality of ImageMagick is typically utilized from the command
16 line or you can use the features from programs written in your favorite
17 programming language. Choose from these interfaces: G2F (Ada), MagickCore
18 (C), MagickWand (C), ChMagick (Ch), ImageMagickObject (COM+), Magick++
19 (C++), JMagick (Java), L-Magick (Lisp), NMagick (Neko/haXe), MagickNet
20 (.NET), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP
21 (PHP), IMagick (PHP), PythonMagick (Python), RMagick (Ruby), or TclMagick
22 (Tcl/TK). With a language interface, use ImageMagick to modify or create
23 images dynamically and automagically.
25 ImageMagick utilizes multiple computational threads to increase performance
26 and can read, process, or write mega-, giga-, or tera-pixel image sizes.
28 ImageMagick is free software delivered as a ready-to-run binary distribution
29 or as source code that you may use, copy, modify, and distribute in both open
30 and proprietary applications. It is distributed under the Apache 2.0 license.
32 The ImageMagick development process ensures a stable API and ABI. Before
33 each ImageMagick release, we perform a comprehensive security assessment
34 that includes memory error and thread data race detection to prevent
35 security vulnerabilities.
37 ImageMagick is available from http://www.imagemagick.org/download to
38 download. It runs on Linux, Windows, Mac Os X, iOS, Android OS, and others.

45 #Features and Capabilities
47 Here are just a few examples of what ImageMagick can do:
49 * Format conversion: convert an image from one format to another (e.g.
51 * Transform: resize, rotate, deskew, crop, flip or trim an image.
52 * Transparency: render portions of an image invisible.
53 * Draw: add shapes or text to an image.
54 * Decorate: add a border or frame to an image.
55 * Special effects: blur, sharpen, threshold, or tint an image.
56 * Animation: create a GIF animation sequence from a group of images.
57 * Text & comments: insert descriptive or artistic text in an image.
58 * Image identification: describe the format and attributes of an image.
59 * Composite: overlap one image over another.
60 * Montage: juxtapose image thumbnails on an image canvas.
61 * Generalized pixel distortion: correct for, or induce image distortions
62 including perspective.
63 * Computer vision: Canny edge detection.
64 * Morphology of shapes: extract features, describe shapes and recognize
66 * Motion picture support: read and write the common image formats used in
68 * Image calculator: apply a mathematical expression to an image or image
70 * Connected component labeling: uniquely label connected regions in an
72 * Discrete Fourier transform: implements the forward and inverse DFT.
73 * Perceptual hash: maps visually identical images to the same or similar
74 hash-- useful in image retrieval, authentication, indexing, or copy
75 detection as well as digital watermarking.
76 * Color management: accurate color management with color profiles or in
77 lieu of-- built-in gamma compression or expansion as demanded by the
79 * High dynamic-range images: accurately represent the wide range of
80 intensity levels found in real scenes ranging from the brightest direct
81 sunlight to the deepest darkest shadows.
82 * Encipher or decipher an image: convert ordinary images into
83 unintelligible gibberish and back again.
84 * Virtual pixel support: convenient access to pixels outside the image
86 * Large image support: read, process, or write mega-, giga-, or
87 tera-pixel image sizes.
88 * Threads of execution support: ImageMagick is thread safe and most
89 internal algorithms are OpenMP-enabled to take advantage of speed-ups
90 offered by multicore processor chips.
91 * Distributed pixel cache: offload intermediate pixel storage to one or
93 * Heterogeneous distributed processing: certain algorithms are
94 OpenCL-enabled to take advantage of speed-ups offered by executing in
95 concert across heterogeneous platforms consisting of CPUs, GPUs, and
97 * ImageMagick on the iPhone: convert, edit, or compose images on your
100 Examples of ImageMagick Usage shows how to use ImageMagick from the
101 command-line to accomplish any of these tasks and much more. Also,
102 see Fred's ImageMagick Scripts: a plethora of command-line scripts that
103 perform geometric transforms, blurs, sharpens, edging, noise removal,
104 and color manipulations. With Magick.NET, use ImageMagick without having
105 to install ImageMagick on your server or desktop.
