mask expansion – harsh angles, not round
hey guys,
does anyone know of a quick way to get angular edges on something?
i have some loose masks that i have drawn, intending to expand the mask outwards to form a cartoon border of sorts. toruble is, even if i draw corners on the mask, when it expands everything rounds out and there are no points. if i did the same thing in illustrator i would have the option of rounded corners or mitre joins etc.
can i get a similar effect in ae?
or, is there a plugin that will take a matte input (or rgb) and “angularise” the image or alpha? i only want lines, no curves.roughen edges does not seem to work, neither do any stylise plugins. roughen cannot “straighten” a curve, only introduce un-evenness, even with large scales or multiple iterations.
thanks,
scott. -

yeah, that’s not the issue, i know how to mask. thanks though.
when you expand the mask using “mask expansion”, the sharp points round out. in illustrator, if you stroke a path, the corners stay sharp unless you tell them otherwise.
i’m trying to figure out how i can expand my mask but keep the sharp corners i drew. -
Hi Dave,
Again thanks for the tip but not quite what I am looking for. If you simply enlarge the mask then the arms and legs of the drawn mask don’t match up with the arms and legs of the person you are trying to mask. It needs to be an expansion or a negative choke of some kind, but so far I haven’t found any combination of effects that will negatively choke (grow) a mask/matte and keep sharp edges and corner points. Oh well, guess I may have to use the cutout filter in photoshop in a batch operation.
Why did adobe stop making AE and PS plugins compatible? I remember when I used to be able to use all my PS plugins in AE.
