NAME
ImageMagick - a free software suite for the creation, modification and
display of bitmap images.
SYNOPSIS
magick [options|input-file]... output-file magick-script script-file
[script-arguments]...
OVERVIEW
Use ImageMagick(R) to create, edit, compose, or convert bitmap images.
It can read and write images in a variety of formats (over 200) includ-
ing PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, WebP, Postscript, PDF, and
SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, shear
and transform images, adjust image colors, apply various special ef-
fects, or draw text, lines, polygons, ellipses and Bezier curves.
The functionality of ImageMagick is typically utilized from the com-
mand-line. It can also be accessed from programs written in your fa-
vorite language using the corresponding interface: G2F (Ada), Magick-
Core (C), MagickWand (C), ChMagick (Ch), ImageMagickObject (COM+), Mag-
ick++ (C++), JMagick (Java), JuliaIO (Julia), L-Magick (Lisp), Lua (Lu-
aJIT), NMagick (Neko/haXe), Magick.NET (.NET), PascalMagick (Pascal),
PerlMagick (Perl), MagickWand for PHP (PHP), IMagick (PHP), PythonMag-
ick (Python), magick (R), RMagick (Ruby), or TclMagick (Tcl/TK). With a
language interface, use ImageMagick to modify or create images dynami-
cally and automagically.
ImageMagick utilizes multiple computational threads to increase perfor-
mance. It can read, process, or write mega-, giga-, or tera-pixel im-
age sizes.
ImageMagick is free software delivered as a ready-to-run binary distri-
bution, or as source code that you may use, copy, modify, and distrib-
ute in both open and proprietary applications. It is distributed under
a derived Apache 2.0 license.
The ImageMagick development process ensures a stable API and ABI. Be-
fore each ImageMagick release, we perform a comprehensive security as-
sessment that includes memory error, thread data race detection, and
continuous fuzzing to help prevent security vulnerabilities.
The current release is ImageMagick 7.0.8-11. It runs on Linux, Windows,
Mac Os X, iOS, Android OS, and others. We continue to maintain the
legacy release of ImageMagick, version 6, at https://legacy.image-
magick.org.
The authoritative ImageMagick web site is https://imagemagick.org. The
authoritative source code repository is https://github.com/ImageMagick.
We maintain a source code mirror at https://gitlab.com/ImageMagick.
ImageMagick is a suite of command-line utilities for manipulating im-
ages. You may have edited images at one time or another using programs
such as GIMP or Photoshop, which expose their functionality mainly
through a graphical user interface. However, a GUI program is not al-
ways the right tool. Suppose you want to process an image dynamically
from a web script, or you want to apply the same operations to many im-
ages, or repeat a specific operation at different times to the same or
different image. For these types of operations, a command-line utility
is more suitable.
The remaining of this manpage is a list of the available command-line
utilities and their short descriptions. For further documentation con-
cerning a particular command and its options, consult the corresponding
manpage. If you are just getting acquainted with ImageMagick, start at
the top of that list, the magick(1) program, and work your way down.
Also, make sure to check out Anthony Thyssen's tutorial on how to use
ImageMagick utilities to convert, compose, or edit images from the com-
mand-line.
magick Read images into memory, perform operations on those images, and
write them out to either the same or some other image file for-
mat. The "-script" option can be used to switch from processing
command line options, to reading options from a file or pipe-
line.
magick-script
This command is similar to magick(1) but with an implied
"-script" option. It is useful in special "#!/usr/bin/env mag-
ick-script" scripts that search for the magick-script(1) command
anywhere along the users PATH, rather than in a hardcoded com-
mand location.
convert
Available for Backward compatibility with ImageMagick's version
6 convert(1). Essentially, it is just an alias to a restrictive
form of the magick(1) command, which should be used instead.
mogrify
Resize an image, blur, crop, despeckle, dither, draw on, flip,
join, re-sample, and much more. This command overwrites the
original image file, whereas convert(1) writes to a different
image file.
identify
Describe the format and characteristics of one or more image
files.
composite
Overlap one image over another.
montage
Create a composite image by combining several separate ones. The
images are tiled on the composite image, optionally adorned with
a border, frame, image name, and more.
compare
Mathematically and visually annotate the difference between an
image and its reconstruction.
stream Stream one or more pixel components of the image or portion of
the image to your choice of storage formats. It writes the pixel
components as they are read from the input image, a row at a
time, making stream(1) desirable when working with large images,
or when you require raw pixel components.
display
Display an image or image sequence on any X server.
animate
Animate an image sequence on any X server.
import Save any visible window on any X server and output it as an im-
age file. You can capture a single window, the entire screen, or
any rectangular portion of the it.
conjure
Interpret and execute scripts written in the Magick Scripting
Language (MSL).
