Any way to sharpen images using more than just AntiAlias?

I'm working on tweaking the Enigma skin to my liking, namely the launcher. On the Enigma DeviantART picture, the launcher images are incredibly smooth. However, the ones included in the skin are very jagged. I added an AntiAlias=1 to see if this would help, and it did, but not nearly enough. I'm wondering if there's a command that will give me a sharper image than just AntiAlias. Thanks!

If you aren't already using it - Rainmeter 1.3 beta is suppose to improve the quality of scaled images.

Yeah, I'm using Rainmeter 1.3

Here's a pic of mine:

And here's the DeviantART one for Enigma: http://kaelri.deviantart.com/art/Enigma-103823591

See how the DeviantART one is so much smoother than mine? I'm not sure why that is, or how to fix it.
