 Just as with a literary work, the preservation and transmission of digital works in different formats depends on the use of a common code, but a binary numeric code rather than a lexical one. If words and their literary uses constitute the medium of literature, then binary code, along with the information it implements, and its artistic uses constitute the medium of digital art. This allows for the possibility that the digital medium contains various sub-media, or “nested” media (Gaut 2010). For instance, within the medium of digital art, the medium of digital visual art comprises artistic uses of computer code specifically to create images. In technical terms, such uses can be referred to as (artistic) “bitmapping”, given that a computer ultimately stores all images (2D and 3D vector) as bitmaps, code sequences that specify the integers assigned to light intensity measurements in a pixel grid. The medium of bitmapping is thus distinguished by a kind of digital technology, but the kind used to produce just those items belonging to the traditional medium of images.
