What defines a vector graphic?

Vector graphics are defined by paths that are determined using mathematical expressions rather than pixels. This allows vector images to be scalable without loss of quality, meaning they can be resized to any dimension while maintaining their sharpness and clarity. This characteristic is particularly useful in graphic design applications such as logos, illustrations, and typography, where the image often needs to be presented in various sizes.

In contrast, pixel-based images, like photographs, are made up of individual tiny squares known as pixels, which can become blurred or pixelated if enlarged beyond their original resolution. Image creation techniques that utilize photographic methods rely on these pixel-based formats. Animated images, on the other hand, involve a sequence of frames but do not define the structure of the images themselves as vector graphics do. Therefore, the defining characteristic of vector graphics is the use of paths and mathematical equations, providing versatility and precision in design.
