Scripting with ImageMagick

ImageMagick is an awesome package of graphics manipulation tools. You can use these tools to perform many of the same jobs that you’d perform with GUI-type tools such as The GIMP and Adobe Photoshop. But, the ImageMagick tools are command-line tools, which allows you to use them in scripts in order to automate many types of jobs. These scripts can either be normal shell scripts, or scripts that use the ImageMagick scripting environment.

Topics in this chapter include:

Converting non-standard filename extensions
Installing ImageMagick
Displaying images
Viewing image properties
Resizing and customizing images
Batch-processing image files
Using Fred’s ImageMagick scripts

If you’re ready, let’s get started.
