Performing Image Magic with ImageMagick

“Whether you know it or not, there’s a good chance you’ve
already used ImageMagick, at least if you’re a Linux user. It’s the
image processor behind many graphics-related applications, and for
good reason. With this one tool, you can perform dozens of common
image manipulations and conversions from the command line or within
a script/application. ImageMagick can convert, transform, draw,
decorate, animate, and composite images. It can be used from the
command line for quick needs or built into a more complex software
suite. This guide will cover some of the most “magical” features of
ImageMagick and provide examples of how to use it to solve everyday
tasks.

“A note about convert: The command name convert will be used
multiple times throughout this guide. It’s one of several commands
to access ImageMagick’s features, not just converting between
types. The fact that we begin a command with the word convert does
not necessarily mean we are converting from one image format to
another.”
