PostScript: Perbezaan antara semakan

'''PostScript''' ('''PS''') is a dynamically typed [[concatenative programming language|concatenative]] [[programming language]] created by [[John Warnock]] and [[Charles Geschke]] in 1982. PostScript is best known for its use as a [[page description language]] in the electronic and [[desktop publishing]] areas.

 

The concepts of the PostScript language were seeded in 1976 when [[John Warnock]] was working at [[Evans & Sutherland]], a famous [[computer graphics]] company. At that time John Warnock was developing an interpreter for a large three-dimensional graphics database of [[New York]] harbor. Warnock conceived the [[Design System]] language to process the graphics.

 

 

Once the ''[[de facto]]'' standard for electronic distribution of final documents meant for publication, PostScript is steadily being supplanted in this area by one of its own descendants, the Portable Document Format or [[Portable Document Format|PDF]]. By 2001 there were fewer printer models which came with support for PostScript, largely due to the growing competition from much cheaper non-PostScript ink jet printers, and new software-based methods to render PostScript images on the computer, making them suitable for any printer (PDF provided one such method). The use of a PostScript laser printer still can, however, significantly reduce the CPU workload involved in printing documents, transferring the work of rendering PostScript images from the computer to the printer. PS is still an option on most "high end" models.
