Inside QImage (with a touch of Qt Quick and OpenGL)

In computer graphics, pixels encoding the RGBA color space information must be stored in computer memory (or in files on disk). In most cases four equal-sized pieces of adjacent memory are used, one for each channel, and a 0 in a channel indicates black color or transparent alpha, while all-1 bits indicates white or fully opaque alpha. By far the most common format is to store 8 bits (one byte) for each channel, which is 32 bits for each pixel.
