Use PDF document in Flash?

Hi folks, happy new year!

Quick question: Since Adobe makes both PDF and Flash, is it possible to open a PDF document inside a Flash application? I would like to have a PDF document as the background of my Flash drawing package, and then be able to draw on top of it using some flash tools (like pencil, polygons, etc) that I am making.

I cant seem to find any hints on how to do this.
