摘要
介绍一种通用图形象素读写子程序的设计原理、实现方法及编程。这种图形象素的读写不仅可以增强IBM-PC BASIC中的LINE语句、PSET语句和POINT语句的功能,增加画点及画线色彩的可选择性,而且改变了两线相交简单覆盖的缺点,此设计方法在计算机图形学中将发挥其作用。
This paper introduces design principle,implementation method,and programming of the graphic pixels read /write subroutine. This graphic pixels read /write methods can strengthen the functions of LINE statement,PSET statement,and POINT statement in IBM-PC BASIC. It can strengthen color selectivity of line and dot drawing also. Meanwhile, the defects of poor coverage with two-line is eliminated. This design method will play an important role in computer graphics.
