A method of improving edge rendering of objects includes dilation (or
contraction) of an object's tag plane by one or more pixels into the
surrounding region, with the adjacent tag region having a corresponding
contraction (or dilation). The objects of interest (e.g., white text) are
first identified; the corresponding object tag plane is then spread or
choked, in a fashion analogous to trapping. In the case of negative text
on a tint background, by expanding the tag plane for the negative text
object, the text hint would be forced one pixel into the tint object
plane everywhere along the perimeter of the negative text. This could
then enable greatly improved negative text rendering.
