A Method of Displaying Transformed Picture Rectangles Using GKS Raster Functions

摘要

AbstractThe GKS raster functions Fill Area and Cell Array allow area primitives in Computer Graphics to be used in a GKS environment.In implementing these functions, the computing time and memory required are important factors in deciding their usability especially for interactive work. The trend in the implementation of algorithms for such primitives is to use specialized hardware.In this paper, algorithms are introduced which are suitable for computers of low and middle efficiency and provide a sufficient image quality and an acceptable response time for dialogues.
