We also support sub-commands for compatibility with ImageMagick version 6:

save any visible window on an X server and outputs it as an image file. You can capture a single window, the entire screen, or any rectangular portion of the screen.
magick mogrify
resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more. Mogrify overwrites the original image file, whereas, magick writes to a different image file.
magick montage
create a composite image by combining several separate images. The images are tiled on the composite image optionally adorned with a border, frame, image name, and more.
magick stream
a lightweight tool to 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 desirable when working with large images or when you require raw pixel components.
Examples
Resize an image
magick test.png -resize 2400x output-big.png
2400x is the width, the height is calculated to keep the aspect ratio.
use 2400x1800 to set the height as well.
or x1800 to set the height and calculate the width.
NOTE: for .svg to .png better use inkscape:
inkscape zurich.svg --export-type=png --export-filename=zurich.png --export-width=2000
Resize canvas
magick test.png -resize 580x281 -background transparent -gravity center -extent 580x281 listpage-logo.png
