Vector images / vector graphics / vector clip art that use geometrical primitives such as points, lines, curves, and shapes or polygon(s), are all based on mathematical equations, to represent images in computer graphics. They contain information about the direction of the line or curve, how thick the line is, and what color or pattern fills the shape.
Vector images can, quite easily, be converted to bitmaps in a process called rasterizing. However, in 3D computer graphics, vectorized plane representations are most common (bitmaps can be used for special purposes such as surface texturing, height-field data and bump mapping).
Corporate organizations, portrait studios and public are now exploiting the various advantages of vector images and vector illustration / vector graphics than other conventional formats. Scalability to any size without much loss of quality makes it ideal for portraits, logos or other images that require resizing.
