400 by 400 pixels is not enough to resolve the image. With normal anti-aliasing, rendering at 1080 by 1080 was not quite enough. 2000 by 2000 was enough.

Even with custom anti-aliasing [ 0.1, 4, 9 (3x3) ], 400 by 400 didn't come out well. Often rendering the image larger and reducing it afterwards works better than trying to improve the anti-aliasing.

I suspect that Kerry Mitchell rendered it at 2000 by 2000 and used another program to reduce it to 400 by 400. I did that and it looked just like his illustration. Good free programs for image reduction and other image manipulation include Irfanview and FastStone.

De nada.

(That nearly exhausts what Spanish I remember from high school many decades ago.)

In this case, you can also try to use the "Non-adaptive" anti-aliasing option. The other options use adaptive anti-aliasing, where a pixel is anti-aliased only if it differs from its neighbors. That usually works well, but not with these black-and-white images, because fine filaments are easily missed.
