These operations create interesting images. For example, try these out: display -resize 50% -monochrome *.JPG display -resize 50% -colors 8 *.JPG But there are others that aren't available from the menu, including ‑monochrome, which converts the image to black and white (not grayscale), and ‑colors, where you can specify how many colors to use in the image. Many of the operations in the menus above can also be done by adding an option in the command line. For example, if I'm displaying a directory of digital images that are larger than my screen size, rather than resizing them individually after they appear on my screen, I can specify: display -resize 50% *.JPG In my Fedora, Browse Documentation took me nowhere.Īlthough display's GUI interface provides a reasonably competent image editor, ImageMagick also provides 89 command-line options, many of which correspond to the menu items above.
