About vector graphics
Vector graphics are made up of mathematically defined lines and curves called vectors. This means that you can move, resize, or change the color of a line without losing the quality of the graphic.
Vector graphics are resolution-independent--that is, they can be scaled to any size and printed at any resolution without losing detail or clarity. As a result, vector graphics are the best choice for representing bold graphics that must retain crisp lines when scaled to various sizes (logos, for example).
Example of a vector graphic at different levels of magnification
Note: Because computer monitors can display images only on a grid, both vector graphics and bitmap images are displayed as pixels on-screen (see Monitor resolution).
