Raster-based graphics applications are becoming widespread. This paper provides a critical review of the support provided within GKS (Graphical Kernal System) for such applications. The use of GKS by applications using image space algorithms and the use of GKS for the control of memory-mapped displays is discussed in depth.
Recent developments in semiconductor technology have made raster scan graphics displays a cost-effective solution to the requirements of most computer graphics systems. Therefore, it is important that the proposed international standard for graphics system software (G KS) 1 can satisfactorily support devices of this type.
Many raster-based devices are used to support vectorstyle operations. GKS will support such systems via functions associated with the fundamental actions of the more traditional calligraphic display devices. However, the point sampling nature of raster representations has led to the development of techniques which exploit this property to gain computational efficiency. The suitability of GKS for applications using these techniques is discussed in this paper.
