The DPS X server module allows PostScript applications to display their output on NCD terminals. Such local servicing of DPS requests speeds application processing and reduces host and network loading.

NCD's DPS extension is based on Adobe's Display PostScript Level 2 software, supports true WYSIWYG two-dimensional graphics, and provides access to all Type 1 Scaled Font Libraries.

The Display PostScript imaging model is device-independent, allowing graphics to look the same on any supported platform. An application that uses Display PostScript works and appears the same on all supported platforms without modification of the application.

Display PostScript performs the following functions:

• Allows applications to scale, rotate, and render text, graphics, and scanned images at any angle
  

• Scales fonts to any point size
  

• Automatically adjusts the colors appearing in color graphics and scanned images on monochrome or grayscale monitors or on monitors with limited color selections
  

• Renders graphics that use Bézier curves
  

• Allows users to import and display Encapsulated PostScript (EPS) files in applications that support this format
  

• Automatically adjusts output to the current screen resolution so that an application looks the same on any screen
  

• Allows easy porting of application programs to other DPS environments
