What defines a vector image?

A vector image is defined by its use of mathematics to create points, lines, curves, and shapes that can be scaled infinitely without losing quality. This means that vector images are composed of paths defined by a start and endpoint, along with other points, curves, and angles. This allows for the creation of intricate designs that maintain their clarity regardless of the size at which they are displayed or printed.

The emphasis on defining shapes through mathematical equations is crucial because it distinguishes vector graphics from raster graphics, which are made up of a fixed grid of pixels or colored dots. The resolution independence of vector images means they can be resized easily for various applications, such as logos or illustrations, without any degradation in quality.
