How to use images as Icons in Sencha 2.2

Hi,

I have some images that I want to use as Icons in my app. I am aware that in Sencha 2.2 and above, Icons are used as fonts. So I tried to covert the images into SVG format and tried to covert it into a font using IcoMoon.

When I converted the images into SVG format, the images got distorted.

Any Ideas... How to achieve this??

Thanks in Advance.
