基于嵌入式Qt的字模提取技术

With the wide application of embedded technology，the requirement to products'performance of human-computer interaction continues to improve , fonts of characters used on embedded systems or devices become more and more rich , the traditional single dot matrix librarys have been unable to meet the needs of printing and display . Based on the analysis of character displaying principle and font library, combined with embedded Qt programming, this paper describes a method of acquiring dot matrix that used in embedded systems, we can directly acquire any font of characters' matrix on embedded devices using this method .
