Current Chinese font library generation systems bear a major drawback that the user is required to write all characters contained in the font library, which is rather boring and time consuming. This paper proposes a system to automatically generate Chinese font libraries of high quality based on component assembling. An input set of a few characters for users is selected to write according to the instructive information of Chinese characters. Then components of each written characters are extracted. Several selected components are combined to construct each unwritten character. Finally the complete Chinese personal font library is obtained, which contains 6763 Chinese characters according to the GB2312 standard. Experimental results show that the proposed system can generate personal Chinese font libraries with dramatically shorter time and still keep excellent quality.
