Notes

The result is not guaranteed to be 100% accurate. Automatic processing cannot always understand the artist's exact intention, so some pixels may need to be manually corrected after applying AAAA.

Processing time depends on the sprite size and settings. Large canvases can take noticeably longer to process, especially when working with multiple layers or frames.

For best results, review the generated result after applying the effect and make any small corrections that are necessary.

AAAA is intended to speed up repetitive anti-aliasing work, not completely replace manual pixel-art editing.
