Vector Images

Vector Images

Vector imaging is the use of lines, polygons, shapes and curves to represent images in computer graphics. Unlike JPEGS and other types of images, Vector images are not made up of a grid of pixels, Instead, vector graphics are made up of paths, which have a definitive start and end point. A path can be a line, a triangle, or a curvy shape. 

Because vector images aren't made up of dots, they can be scaled up to a larger size and not lose image quality, unlike if you scared up a raster image. This makes vector images ideal for logo's, which can be small enough to fit something such as a business card, or large enough to fill a large poster or billboard. Vector images usually consist of the following extensions: .AI .EPS .SVG .DRW
