Digital Images: Concepts and Terminology

Abstract

Now that you have an understanding of the primary areas of new media content and the file formats that Android Studio and the Android OS support, it is time to knock these pieces of the multimedia pie down one by one, two chapters at a time. Let’s start with digital imaging, as it is the most prolific, popular, and mainstream type of new media. I’ll cover everything in this chapter, from a pixel building block that makes up these raster images to the array that contains the pixels and the resolution and aspect ratio that defines that array. You will look at pixel characteristics such as location, color channel, alpha channel, color depth, and even advanced topics, like PorterDuff blending modes and NinePatchDrawables, both of which are supported in the Android API, with their own classes, methods, and constants.
