Questions tagged [vector-graphics]

Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon(s), which are all based on mathematical equations, to represent images in computer graphics. Images are drawn at run-time from the information stored, and so vector images do not get distorted after zoom/resize etc.
