摘要 |
A system for uniformally expanding a proportionally spaced character display in order to properly align the smallest characters of the character set without affecting the proportional relationship of the characters in the character set. An extra vertical scan line is added to the displayed characters at an escapement increment determined by the character of the character set requiring the greatest proportion of scan line expansion per character width in order to achieve proper character definition. Those characters requiring an additional unit of escapement to be properly defined utilize the added vertical scan lines and excess added vertical scan lines are distributed in the "white space" between characters. The added display columns have the same affect as increasing the number of scans per unit of character escapement. |
