Abstract

A grid-fitting method for Chinese fonts at a size smaller than 20 grid units to achieve a high-quality display is presented. The basic idea behind the proposed method is to adopt several grid-fitting rules with a gray-scaling strategy. The major procedures include supersampling, adjusting the position and width of strokes, gray-scale filtering, and subsampling. The experimental results show that the jagged edge induced by the coarse resolution can be removed and that the rendition of character details and the contrast are also improved, revealing that the character's clarity and smoothness can be enhanced for a higher legibility with comfortable reading.
