Page Description Language

Page Description Language

A page description language (PDL) is a language that describes the appearance of a printed page in a higher level than an actual output bitmap. An overlapping term is printer control language, but it should not be confused as referring solely to Hewlett-Packard's PCL. PostScript, one of the most noted page description languages, is a fully fledged programming language, but many PDLs are not complete enough to be considered a programming language. The markup language adaption of the PDL is the page description markup language.

Page description languages are textual or binary data streams. In principle, the same data stream could be rendered multiple times to generate multiple copies of the same image. They are distinct from graphics APIs such as GDI and OpenGL that can be called by software to generate graphical output.

Famous quotes containing the words language, page and/or description:

    Our goal as a parent is to give life to our children’s learning—to instruct, to teach, to help them develop self-discipline—an ordering of the self from the inside, not imposition from the outside. Any technique that does not give life to a child’s learning and leave a child’s dignity intact cannot be called discipline—it is punishment, no matter what language it is clothed in.
    Barbara Coloroso (20th century)

    Envy has blackened every page of his history.... The future, in its justice, will number him among those men whom passions and an excess of activity have condemned to unhappiness, through the gift of genius.
    Eugène Delacroix (1798–1863)

    He hath achieved a maid
    That paragons description and wild fame;
    One that excels the quirks of blazoning pens.
    William Shakespeare (1564–1616)
