As the present invention is to improve the existing technique of in processing the outline font characters, by real-time implemented using a bit OR / AND operation the outline of the letter character, the pre-operation the outline of the letter character to increase the source data, the invention, a predetermined pixel shift that after bit operation applied to generate the blurring data and blurring data to the original data back to a copy of a plurality of directions from the source data to obtain the original data of the first syllables sequentially from the memory of the device re-bit operations applied to a technology for real-time implementation of the outline font character is processed. According to the invention, the bit map in processing the outline by using the original data and the copy data of the original data of the font, embedded with a relatively low-end process because it uses only the real-time simple memory copy and bit OR / AND operation in the system it can smoothly perform the outline processing of the character string.
