Now that you have an understanding of the positioning of pixels using an x,y grid, which defines the image resolution as well as the image aspect ratio, it is time to look inside of each pixel, and see how it defines its color space. Whereas a digital image holds its resolution and aspect ratio, from a data perspective, each pixel contains its own characteristics, such as the x,y grid (array) position, color composition, transparency or opacity, blending mode, and the like. We will be looking at all of these areas individually, each in their own chapters within this book.
