Capturing screenshots is a very nifty feature of PhantomJS, and we can make a lot of useful applications with it. There are several services using this to provide the users with the capability to create varieties of screenshots of their page on different sizes; some also provide the facility of viewing and capturing pages in different hues or possible color blindness combinations. We can do a lot more using this feature, and we can actually integrate this feature using location-based services, about which we are going to learn more in the next chapter.
