Importing Characters

Hello,

I’m just joining the Toon Boom world as well as the animation world! So I’m pretty new to this all so I apologize if this question seems silly. I’m having a very hard time figuring this cut out animation process. Every time I try to import my characters it bring in the entire image including the white background (entire page) how do I stop this or is there other videos out there to better explain the process because the one’s I’ve found haven’t been much help. All tips and tricks are welcomed! LOL
