ImageMagick (Legacy)

Use ImageMagick^® to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 200) including PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, 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.

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 license.

ImageMagick utilizes multiple computational threads to increase performance and can read, process, or write mega-, giga-, or tera-pixel image sizes.

The current release is ImageMagick 6.9.11-59. It runs on Linux, Windows, Mac Os X, iOS, Android OS, and others.

The authoritative ImageMagick version 6 web site is https://legacy.imagemagick.org. The authoritative source code repository is https://github.com/ImageMagick/ImageMagick6. Find the latest release of ImageMagick, version 7, at https://imagemagick.org.

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 ImageMagick version 7, we aim to improve the design based on lessons learned from the version 6 implementation.

Features and Capabilities

Here are just a few examples of what ImageMagick can do for you:

	create a GIF animation sequence from a group of images.
Color management	accurate color management with color profiles or in lieu of-- built-in gamma compression or expansion as demanded by the colorspace.
Command-line processing	utilize ImageMagick from the command-line.
Complex text layout	bidirectional text support and shaping.
Composite	overlap one image over another.
Connected component labeling	uniquely label connected regions in an image.
	add a border or frame to an image.
	, .
	implements the forward and inverse DFT.
Distributed pixel cache	offload intermediate pixel storage to one or more remote servers.
	add shapes or text to an image.
Encipher or decipher an image	convert ordinary images into unintelligible gibberish and back again.
Format conversion	convert an image from one format to another (e.g. PNG to JPEG).
	correct for, or induce image distortions including perspective.
Heterogeneous distributed processing	certain algorithms are OpenCL-enabled to take advantage of speed-ups offered by executing in concert across heterogeneous platforms consisting of CPUs, GPUs, and other processors.
High dynamic-range images	accurately represent the wide range of intensity levels found in real scenes ranging from the brightest direct sunlight to the deepest darkest shadows.
Image calculator	apply a mathematical expression to an image, image sequence, or image channels.
Image gradients	create a gradual blend of two colors whose shape is horizontal, vertical, circular, or elliptical.
Image identification	describe the format and attributes of an image.
ImageMagick on the iPhone	convert, edit, or compose images on your iOS device such as the iPhone or iPad.
Large image support	read, process, or write mega-, giga-, or tera-pixel image sizes.
Montage	juxtapose image thumbnails on an image canvas.
	extract features, describe shapes, and recognize patterns in images.
Motion picture support	read and write the common image formats used in digital film work.
	, .
Perceptual hash	map visually identical images to the same or similar hash-- useful in image retrieval, authentication, indexing, or copy detection as well as digital watermarking.
	blur, sharpen, threshold, or tint an image.
	insert descriptive or artistic text in an image.
Threads of execution support	ImageMagick is thread safe and most internal algorithms execute in parallel to take advantage of speed-ups offered by multicore processor chips.
	resize, rotate, deskew, crop, flip or trim an image.
	render portions of an image invisible.
Virtual pixel support	convenient access to pixels outside the image boundaries.

shows how to use ImageMagick from the command-line to accomplish any of these tasks and much more. Also, see Fred's ImageMagick Scripts: a plethora of command-line scripts that perform geometric transforms, blurs, sharpens, edging, noise removal, and color manipulations. With Magick.NET, use ImageMagick without having to install ImageMagick on your server or desktop. Finally, see Snibgo's ImageMagick Cookbook for Windows-based ImageMagick scripting.
