Below, I show how to access the command line in each of Linux, Windows, and Mac OS. Most Linux users will be familiar with the command line but Windows and Mac OS users may not have had a reason to use the command line until now. One may also create scripts that run ImageMagick commands, but scripting is a more advanced topic not covered in this post. This makes is easy to perform common image editing tasks. One can create a set of commands and save them in a text file, then copy-and-paste commands from that file whenever they are needed. While ImageMagick provides a basic graphical user interface, it is easiest to use from the command line. If ImageMagick is not installed on your computer yet, skip to the end of this post to see how to install ImageMagick on either Linux, Windows, or Mac OS X. To learn more about what ImageMagick can do, see the ImageMagick documentation and also see the ImageMagick examples page. ImageMagick may be used to perform a wide variety of graphics editing tasks and can even be used to create new images from the command line. You may also incorporate ImageMagick into shell scripts, batch files, or other programs to automate the preparation of images for your blog. Using ImageMagick makes it easy to batch process all images in a folder by entering a simple command. It takes too long to edit a large number of images one by one in an image editor like Photoshop or Gimp. We may use ImageMagick commands to resize, rotate, and transform images, adjust image colors, apply various special effects, or draw text, lines, and shapes. It can read and write images in over 200 formats. ImageMagick is a software suite that creates, edits, composes, or converts bitmap images. I will show how this can be done on each of the major operating systems: Linux, Windows, and Mac OS X. In this post, I will show how to install and use ImageMagick to perform the simple image conversions bloggers typically need. However, most bloggers will use only a few simple options. ImageMagick is a powerful image manipulation tool with an intimidatingly large set of options and subcommands. I want to do this quickly and easily so I use ImageMagick, an open-source command line image editor. Usually I want to add a border around each image and I sometimes want to reduce the size of images that are too large. When writing a blog post about a technical topic, I often capture a lot of screen shots that I need to edit before adding them to my blog article.
