2D computer graphics are mainly used in applications that were originally developed upon traditional [[printing]] and [[drawing]] technologies, such as [[typography]], [[cartography]], [[technical drawing]], [[advertising]], etc. In those applications, the two-dimensional [[image]] is not just a representation of a real-world object, but an independent artifact with added semantic value; two-dimensional models are therefore preferred, because they give more direct control of the image than [[3D computer graphics]] (whose approach is more akin to [[photography]] than to
In many domains, such as [[desktop publishing]], [[engineering]], and [[business]], a description of a document based on 2D computer graphics techniques can be much smaller than the corresponding digital image—often by a factor of 1/1000 or more. This representation is also more flexible since it can be [[rendering (computer graphics)|rendered]] at different [[Image resolution|resolution]]s to suit different [[output device]]s. For these reasons, documents and illustrations are often stored or transmitted as [[graphics file format|2D graphic files]].
