Design of embedded multi-language lattice font based on QT

The paper analyzes the shortage of QT font interface compared with embedded system. For the open source QT version, the paper designs a self-defining and multi-language lattice font which not only has fast performance of QPF lattice font and multi-language support of TTF vector font, but also has multiple features and supports extracting multinational language font with different styles which are to be stored in the same font. The font realizes seamless integration with QT, and the font is applicable to multi-language application and development of embedded interactive interface based on QT.
