Font conversion device |
摘要 |
A font data output method that applies bandwidth limitation to binary font data using a two-dimensional low-pass filter, and applies gain of one or more to a multilevel-value data group obtained by reduction at a predetermined ratio according to the distribution of values in the multilevel-value data group to generate the gradated font data. Using this method, the loss of line and character density in the font data due to a high reduction ratio can be prevented.
