AA Question

[samw3]

I always had trouble with AA-ing a gentle curve--especially the part near 45 degrees.



Do any of the pros have time to edit this and show me how you do it?   Every time I try the line seems either flat or fatter than it should be, or I end up using way too many colors...

Thanks!

I've always been puzzled by how to do a proper curve in pixel art - even just the line art. If you can't go from 2-2-2-2 to 1-1-1-1-1, you've got to have some jaggies (2-1-2-2-1) and minimizing them I don't know about.



I need more AA practice - that wound up blurry and over AAd. Harder to AA from white on to black than reversed, too. As is apparent from my edit, errors that might look okay from white to black are blatantly clear when flicking a negative switch. I wonder - do the pros ever invert the colours of pieces they're working on just to check the AA?

Edit: Ha, I made the silly mistake of not touching the initial line art. Lovely edit below me.

I only tackled the first jaggie on both sides of the inside of the curve, as I assume that's what you wanted. I used 25%, 50%, and 75% grays. Note that hue doesn't matter too much so it shouldn't be too hard finding colors that are usable without having to add new ones, in a colored piece.

It's very subtle, but I think it works, the jaggie is no longer noticeable. You don't want to overAA, anyway.



I'm far from a pro, though.

To expand on what DD said... (Stole your colours too )



Perhaps a bit overdone, my aa sure as hell isn't perfect but you can see that the aa needn't only hug the outlines, you can touch the white too

Thanks everyone for giving this a try.  I suppose it just is a tricky thing.  I have to say that Dr D's version is the cleanest and really something I'd like to see in my work.  Thanks for the contributions, I've learned a lot.
