AAit is a morphological anti-aliasing plugin, developed by MiLai(ZzStarSound 中梓星音), used in Ae.
This plugin is free-for-use now.
If you apply AAit to a pixel-art image drawn with pixels bigger than 1x1,
change the "Pixel width/height" to the corresponding size. (e.g. 2x2)
Leave it to default otherwise.
"Area reference" is used to set Object ID info. See the figure below for more details.
Increase the "Edge threshold" to 10 or more if you are processing a colorful picture
Note: Only the edge of the ObjectID is the valid AA area. If you want to AA the whole image, set "Area reference" to NONE and "Edge threshold" to 10
