Optical justification of text

摘要

Method and apparatus for justifying text rendered from a digital font at an output pointsize. The invention includes using a kerning value for a character pair including a space character and a nonspace character to place the nonspace character at a margin. The invention can be used in conjunction with a font having first kerning metrics for a small pointsize and for a different large pointsize. The kerning value can be obtained by interpolating the small pointsize metrics and the large pointsize metrics.
