微计算机控制的多画面交互式彩色图形系统

本文阐述一个低成本、应用灵活的交互式彩色图形系统.它包含一个用于画面前后台显 示处理的多画面存贮管理部件,具有彩色图形、字符、伪彩色图象和动画四种显示模式.系统 的交互功能(例如图象/图形的输入,修改与画面编辑等)由系统软件和一个易于扩充的图形命 令语言定义,因此可望该系统能在多方面获得应用.

A Microcomputer Based Multipicture Interactive Colour Graphics System

A low-cost interactive colour graphics system that supports various application environments is described. Hardware assistance for multipicture management is provided, using a method that allows foreground-background display processing of pictures. The system has four display modes: colour graphics and/or colour character modes, pseudocolour image mode and animation mode. Most of the interactive functions, such as image/graphics inputting,, modifying and editing, are defined by the system software and an expandable graphic command language, thus permitting the exploration of different ways of using this kind of system.
