Vector font display optimization method based on vxWorks system

The invention discloses a vector font display optimization method based on a vxWorks system. The method comprises the steps of cutting of a FreeType engine library, initializing of a vector font library, unicode transcoding setting of Chinese characters, type acquiring of a FreeType function library, output displaying of vector fonts, mixed displaying of the vector fonts and backgrounds and display optimizing of the vector fonts. According to the method, a trading-time-for-space optimizing method is adopted to solve the consumption of vector font displaying time and save established charactertypes, character contours and textures, and whether or not the characters are established is searched and determined through inner codes to increase the displaying efficiency. The method can be extensively used in the vxWorks system, the method can be adapted to as long as graphic display fields of the vxWorks system and an OpenGL/ES library are adopted, software upgrading can be conducted on formed hardware to change the
