If you are just getting acquainted with ImageMagick, start with the magick program. Click on the program name to get details about the program usage and a list of command-line options that alters how the program behaves. Here is a short description for each command-line tool. Expect a descriptive message and an exit status of 1 if any exception occurs such as improper syntax, a problem reading or writing an image, or any other problem that prevents the command from completing successfully. The ImageMagick command-line tools exit with a status of 0 if the command line arguments have a proper syntax and no problems are encountered. For instance, if you need to process an image dynamically from a web script or apply the same operations to multiple images, or if you need to repeat a specific operation on the same or different images at different times, using a command-line utility like ImageMagick may be more efficient. While many people are used to using graphical user interfaces (GUIs) like Gimp or Photoshop to edit images individually, these tools may not always be practical. ImageMagick is a collection of command-line tools that can be used to modify and manipulate images.
