Bug Description
I normally use inkscape to create icons in small sizes, and anti-aliasing is a very important part of making them look good. Normally, the "export as bitmap" tool does a poor job, and I have to fix it up in a bitmap program (commonly GIMP or Photoshop).
I will show here an example with both the bug (as I see it) and how I fix it manually.
These are SVGs, they are three sizes of an icon of a small open-source program I'm making in my spare time:

They have 1px black strokes and 1px inner strokes of a light shade: this kind of thing creates even more aliasing, but helps achieve a crisp look if anti-aliasing is very good. It's recommended to use this trick in the Tango icon theme guidelines (http://
Now, this is what happens if we just "export as bitmap":
http://
As you can see, the anti-aliasing is very poor. So what this makes me do to fix it, manually? Simple: I just export in 1440 DPI, open in GIMP or Photoshop, and resize down to the correct size with either bicubic or Lanczos/Bicubic sharper. This is the result:
http://
As you can see, it's much better.
In my very old machine (1 core @1.6GHz, 768 RAM) it takes an insignificant amount of time for a 48px icon, and I wouldn't mind it taking exponentially more for larger images. I took waaay more than a minute to make an icon, why not wait a bit for a better result? At least I'd like a checkbox somewhere that toggles a slower but higher quality algorithm that anti-aliases properly.
Also, it's not just because these are icons that I notice this kind of artifact; my girlfriend uses Inkscape to draw anime (http://
Thank you for your time reading this, I hope you consider this suggestion. Inkscape is a very valuable program for me and others.

By the way, the three first urls are now giving 404, because I lowercased the folders' names. Here they are, fixed: msile.googlecod e.com/svn/ trunk/graphics/ icons/msile/ msile-16px. svg msile.googlecod e.com/svn/ trunk/graphics/ icons/msile/ msile-32px. svg msile.googlecod e.com/svn/ trunk/graphics/ icons/msile/ msile-48px. svg
