Tutorial: Clean Anti-Aliasing

Tutorial: Clean Anti-Aliasing
Requirements: GIMP (http://gimp.org )


This video tutorial shows you how to anti-aliase your sprites without feathering the outer edges, a problem many game makers and animators run into. This also teaches how to add basic transparency to sprites (E.g. for Flash developers).

1. Open GIMP and browse for the sprite you want to anti-aliase. Indexed images can't be used.

2. Select the Magic Wand tool and then click on any empty space that isn't part of your sprite. If you have "space holes" in your sprite, hold Shift while clicking to add up that space, too.

3. Now go to "Layers" -- "Transparency" -- "Add Alpha Channel". If you can't, that means there already is one and you can skip this step. The reason you have to use alpha channels instead of pure white in the background, is simply because the sprite will still blend a little with the background when anti-aliased, and that's clearly not what we want.

4. Now right-click on the empty space and select "Cut" under "Edit".

5. Re-select all the empty space. When done, right-click on it and click on "Invert" under "Select" (Thus, giving us a full selection of the whole sprite).

6. Finally, go to "Filters" -- "Enhance" -- "Anti-Aliase". This will anti-aliase the selection.

Its still horribly jagged and unsmooth. Just learn to do it yourself, thats the solution.

[LassesIndex]

You can always move the outlines into a seperate layer and then do a few blur/sharpening tricks to make the lines smoother.

Or you can do it your way. It's a matter of choice and preference, I guess =P

[LassesIndex]

I use that theme simply for the sake of speed =P
