Spark SVG renderening options in Flex?

I am a bit new to vectors so bear with me. What I am trying to do is make a toolbar in Flex from some vector graphics I have created in Illustrator.

The problem is when I import the vectors into Flex as an SVG some scaling(?) seems to occur, pixelating my once crisp vector.

Initially I thought the problem was because my graphics were small (32 x 32) so I tried hard coding one directly into my Flex mxml file and it looks great. Here's a comparison :

Obviously hardcoding in not a great solution, besides which I had intended to have the vectors within Spark images because I need tooltip functionality.

This is the SVG file I am using :

Would really appreciate any help / pointers as to how to get this working properly.

Using Flex 4.6.0 by the way.

Thanks!

I notice that your SVG file specifies hard-coded height and width in the SVG node itself:

... width="32.469px" height="33.625px" viewBox="0 0 32.469 33.625" ...

but in your "hard-coded" version, that node obviously isn't there. Could that be the difference? If Flex rasterizes the vector drawing to be exactly 33.625px high, and then the <s:Image/> is a slightly different size in the display list, it might try to scale it as a bitmap, which sort of defeats the whole purpose of vector graphics.

Does it get better if you just drop those size attributes?
