Vector fonts –Fonts represented with object-oriented graphics, also known as scalable fonts or outline fonts. An example of a vector font system is PostScript. Vector images –Images that are defined in terms of mathematical parameters (Bezier curves), which gives the artist or designer control over shape, placement, line width, and pattern. Because the objects are defined geometrically, the visual quality of the shapes does not degrade when enlarged or reduced.
