Anti-Aliasing...

[Blutters]

Can someone explain to me exactly what 2x- and 4x-Anti-Aliasing do?

 

Do they actually raise the quality or only make it appear so by blending the edges between object and background?

As far I was aware that was how it makes the quality better?

[Sy_Accursed]

When different graphical objects are overlaid in an applet or an image, due to difference in background colours etc; previously smooth edges can appear jagged and pixalated.

 

 

 

This is Aliasing.

 

 

 

Graphics cards are equipped with engines to counter act this aka Anti-Aliasing.

 

 

 

Higher the multipler the smoother the edges are between things such as you're character and the environment.

the "only edges" looks much better but look out... it takes a lot of CPU too, I have mine set on 2x standard

[Blutters]

Thanks, all three of you.

 

 

 

I can't believe it took me this long to realize that taking pictures with 4x-Anti-Aliasing if I'm just going to cut them out anyway is a bad idea...

Runescape like many other games uses a FSAA(full scene anti aliasing) system which works by rendering the game window at you chosen resolution times by a aliasing power. This being two or four in Runescape's case. It then scales this image down to make the final image. This process leads to a smoother gradient between edges.

 

 

 

When cutting out images it should really matter the aliasing setting you have selected as you can always cut slightly inside the images and put a feather on the selection but yeah using the highest anti-aliasing setting will help greatly.

Higher anti-aliasing means smoother images which is actually easier and better to cut out (even without feathering the selections).

I feel the need to re-confirm my understanding;

 

Anti-aliasing takes the edges of the picture and changes their colors to be intermediate between the colors of the picture and the background or other objects that it overlaps in order to make all of the edges appear smooth.

 

If you cut out the main object, then the edges of that object have still been changed to intermediate colors, rather than a basic color that could be re-done to blend with a different background.

 

 

 

All of that said, what I was trying to do was cut some things out and blend them with TIF's background for a signature.

 

So, rather than cutting pictures out of the original RuneScape source with anti-aliasing enabled to where the edges are blending with something brown or tan, wouldn't it be better to use no anti-aliasing to get 'natural edges' to blend them with a background the same color as Tip.It gray?

 

 

 

For the record, you are talking or explaining to someone with a very limited knowledge of picture editing programs. I mostly use Microsoft Paint and a tiny bit of Corel Paint Shop Pro Photo X2 (usually just using the magic wand tool :-# ).

 

I have no idea what feathering is...

[Sy_Accursed]

If you want to cut something out turn anti-aliasing off.

 

 

 

It'll give the character, npc or w/e very defined squared off edges whihc are easier to cut.

 

 

 

Once cut out and either placed into a transparent or otherwise coloured background you can use edge softening tools to smooth things out, where as if you do this with the anti-aliased version the smooth edges means u can cut bits off you shouldn't or end up with random stray colours.

[Blutters]

Thank you very much! I just needed someone to confirm that.

Actually, using no anti-aliasing isn't well and good, because it not only does not take the edges from the background and objects in front of objects (which would be ideal), it also leaves edges on all parts of single objects...
