raster graphic meaning in English

光栅图形

The complex situation of flight requests that the graphics display of cockpit must be dynamic , real - time and legible . but in the raster graphic display system , scale lines and character will be distorted seriously owe to the limited screen resolution in the case of deflection , which affect the display quality . the thesis based on the research of the last graduate student improves the graphics creating arithmetic more and puts forward more effective arithmetic on scale lines and character for high display quality
由于飞行状态复杂，要求座舱内画面显示动态、实时、清晰。而硬件系统采用的是光栅图形显示，字符和刻度线的旋转受屏幕分辨率的限制存在着锯齿走样现象，影响显示效果。本文在上一届研究生研究的基础上，在图形生成算法上加以进一步改进，重点在刻度线、字符的反走样处理上，研究出了更合理的算法，提高了图形显示质量。
