Good Evening

I am hoping that someone will be able to help me out here, as I am getting very frustrated..lol..

I have a couple of chinese symbols that my Mums friend drew for me, and I scanned them onto pc, and then made psp x brushes out of them, but the edges are a bit rough, and I wanted to smooth them, and I also wondered if there is any way of converting the brushes I have made out of them into vector shapes after smooting them, or does anyone knw of a company that would do this for me for a fee.

Hoping someone can help me.

Thankings in advance
Nikki
