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[rg] 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. Use ImageMagick to resize, flip, mirror, rotate,
distort, shear and transform images, adjust image colors, apply
various special effects, or draw text, lines, polygons, ellipses and
B['e]zier curves.
The functionality of ImageMagick is typically utilized from the
command-line. It can also be accessed from programs written in your
favorite language using the corresponding interface: G2F (Ada),
MagickCore (C), MagickWand (C), ChMagick (Ch), ImageMagickObject
(COM+), Magick++ (C++), JMagick (Java), JuliaIO (Julia), L-Magick
(Lisp), Lua (LuaJIT), NMagick (Neko/haXe), Magick.NET (.NET),
PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP (PHP),
IMagick (PHP), PythonMagick (Python), magick (R), RMagick (Ruby), or
TclMagick (Tcl/TK). With a language interface, use ImageMagick to
modify or create images dynamically and automagically.
ImageMagick utilizes multiple computational threads to increase
performance. It can read, process, or write mega-, giga-, or tera-
pixel image sizes.
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.
The ImageMagick development process ensures a stable API and ABI.
Before each ImageMagick release, we perform a comprehensive security
assessment 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.imagemagick.org.

ImageMagick is a suite of command-line utilities for manipulating
images. 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 always 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 images, 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
conserning a particular command and its options, consult the
corresponding manpage. If you are just getting aquainted 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 command-line.
magick
Read images into memory, perform operations on those images, and
write them out to either the same or some other image file
format. The "-script" option can be used to switch from
processing command line options, to reading options from a file
or pipeline.
magick-script
This command is simillar to magick(1) but with an implied "-
script" option. It is useful in special "#!/usr/bin/env magick-
script" scripts that search for the magick-script(1) command
anywhere along the users PATH, rather than in a hardcorded
command location.
convert
Available for Backward compatiblity 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 image
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).
