What are bitmaps primarily composed of?

Bitmaps are primarily composed of pixels, which are the smallest units of a digital image. Each pixel represents a specific color and together they form an image, making up the entire visual representation. This grid of pixels allows for the detailed rendering of complex images, as each pixel's color contributes to the overall picture quality and detail.

In digital graphics, understanding pixels is crucial because they are the foundation of how images are displayed on screens. When you zoom in on a bitmap image, you can see the individual pixels that make up the image, which is a key characteristic of bitmap images. This granular structure is what differentiates bitmaps from other types of images, such as vector graphics, which are composed of lines and shapes defined by mathematical equations.
