#20 How do Digital Images Work?
Computers would be boring without images.
Digital images can be broadly categorized into two kinds: bitmap and vector. In this episode we provide the listener a general understanding of how both bitmap and vector images work. We start with the basics, by explaining pixels, but then we talk about a standard color model, and some specific file formats that most people are familiar with. We finish our discussion by talking about smartphone cameras, image manipulation software, and how images work together to make videos.
Note: In this episode we used the term "graphics card" generically. We could have more accurately said Graphics Processing Unit (GPU) to include embedded GPUs as exist in most devices.
