.png as a smooth Flash mask

Hi

I’m trying to get the attached silhouette figure (png file) to work in Flash as a mask - so a bitmap.

Tried to convert it in Photoshop to a eps file - and the convert to bitmap within Flash - but is resulting in a jagged version. I need it to be an exact copy that will work in Flash as a mask.

Any suggestion or help much appreciated.

Thanx

Dirk
