ABSTRACT:
A method of reducing the size of a character font in a word processor or an office computer. Digitized font data representative of a character font is constructed in a dot matrix consisting of a plurality of rows in an X direction and a plurality of columns in a Y direction perpendicular to the X direction. The first row of dots in the X direction is divided into a plurality of blocks and each block is provided with a ONE or a ZERO depending upon the number of dots included therein. The first row is shifted one dot to the left in the X direction to form a shifted row. The shifted row is divided into a plurality of blocks and each of these blocks is provided with a ONE or a ZERO depending upon the number of dots included therein. ANDs of the respective logical values of the shifted and non-shifted rows in the Y direction are computed to obtain a ONE or ZERO block by block. These consecutive steps are repeated on all the rows in the X direction to thereby provide a ONE or a ZERO for each of the blocks in all the rows. Each of the columns in the Y direction represented by ONEs and ZEROs of the blocks in the X direction is divided into a plurality of blocks. ANDs in the Y direction are computed block by block to decide the blocks whose ANDs are ONEs to be black dots.
