PURPOSE:To reduce the capacity of a frame memory and the use capacity of a disk for a font file by holding two-dimensional coordinates in the font file in addition to basic elements of width, height, and depth as respective character attributes and controlling character patterns as two-dimensional continuous bit images on the frame memory. CONSTITUTION:A font information part 3 is stored with the width of bit patterns, the height of the bit patterns, the number of registered characters, etc., as character output information. Then the size required to develop a bit pattern on the frame memory 8 from the font information part 3 of the font file 7 is taken out and the bit pattern of a bit pattern part 1 is developed on the frame memory 8. The two-dimensional X and Y coordinates of a character and the width and height of the character pattern are taken out of a character attribute part 2 and outputted by rectangle transfer from the frame memory where the bit pattern is developed. Consequently, the memory use capacity and the use capacity of the disk for font file storage are reduced. |
