Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Display PostScript is an on-screen display system. As the name implies, DPS uses the PostScript imaging model and language to generate on-screen graphics. To the basic PS system, DPS adds a number of features intended to ease working with bitmapped displays and improve performance of some common tasks. Early versions of PostScript display systems were developed at Adobe Systems. In 1986, Sun Microsystems developed a totally independent implementation of Adobe's PostScript page description language called NeWS, which rendered on multiple overlapping arbitrarily shaped windows on the display. Unlike Adobe's Display PostScript, NeWS had extensions for handling input devices, events, light weight threads, locks, networking and object oriented programming. NeXT developed a Display PostScript system in cooperation with Adobe in 1987. It was an official Adobe product with its own standards, documents and licensing requirements.
