ABSTRACT:
A character generating device which is capable of creating a clear thickened or thinned (wider or narrower) character by eliminating an improper portion of an outline of a character. According to a character code input from an input portion, a CPU obtains outline font data for one character from a font data storage and transfers the data into a RAM. On the basis of the character code input from the input portion, the CPU searches a head address of a memory storing data for a required character and transfers the data from the address into the RAM. A character thickness processing portion performs character thickening or thinning operations on each point sequence composing each outline of the outline-font character and a point-sequence transferring portion determines, by use of functions or a table, a correct destination and transfers thereto the improper point-sequence on the thick or thin processed outline of the outline-font character.
