With JPEGs, GIFs, and BMP images, these are made up of a grid of pixels. With a vector graphic these are comprised of paths and are defined by a start and end point. A path can be a line, a square, a triangle, or a curvy shape. These paths can be used to create simple drawings or complex diagrams. Paths are even used to define the characters of specific typefaces.
Because vector-based images are not made up of a specific number of dots, they can be scaled to a larger size and not lose any image quality. If you blow up a raster graphic, it will look blocky, or “pixelated.” When you blow up a vector graphic, the edges of each object within the graphic stay smooth and clean. This makes vector graphics ideal for logos, which can be small enough to appear on a business card, but can also be scaled to fill a billboard.
The advantages of a vector illustration are that, no matter how much you zoom in, the quality will stay 100% sharp.
