ImageMagick - is a free software suite for the creation, modification
and display of bitmap images.
convert input-file [options] output-file
Use ImageMagick(R) 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 or you can use the features from programs written in your
favorite language. Choose from these interfaces: 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 and can read, process, or write mega-, giga-, or tera-pixel
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 6.9.10-11. 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. We maintain
a source code mirror at https://gitlab.com/ImageMagick/ImageMagick6.
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.

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 desirable when
