Edge compaction in antialiased images |
摘要 |
A method to compact a diffuse gray edge that is two pixels wide to a state where it is one pixel wide so that it may be well rendered with anti-alias rendering. The method identifies an observation window within continuous tone image data. The method then operates on the pixels within the observation window by: compacting horizontal features within the observation window; compacting vertical features within the observation window; and compacting corner features within the observation window.
