用于嵌入式系统的汉字点阵提取方法

The Methods of Abstracting Chinese Dot Matrix for Embedded Systems

嵌入式系统人机交互性能的重要指标之一是汉字显示打印功能,利用汉字点阵实现此功能是一种简单实用的方法,因此从现有汉字系统中提取汉字点阵是嵌入式系统开发的第一步工作。提取汉字点阵有两种方法,一是从点阵字库中提取,二是从矢量字库中提取,这两种方法在实际开发工作中都得到了应用。详细分析了这两种方法的原理及编程实现,提出了自动扫描嵌入式应用程序生成汉字点阵的方法,这种方法特别适用于建立小型汉字点阵库。

It＇s a simple and practical method to use the Chinese dot matrix to display and print Chinese characters in embedded systems. Therefore,abstracting dot matrixes from the existing Chinese character OS is the first step of developing embedded system. We can abstract dot matrixes from the dot matrix library or from the vector library. Authors have applied both ways in practical applications. This paper analyses the principles and programming of both ways in detail. In addition, this paper proposes a method of auto- scanning source files,this method is best for creating mini dot matrix library.
