I need to crop a picture that I created by code. I think I am supposed to use a mask but I haven’t been able to figure it out. I thought you were supposed to create a picture fill it with black and apply it as a mask to the picture requiring the mask but it’s not working. I’m sure it’s simple but can someone help get me started? 
Have you looked at all the parameters of DrawPicture? That might help you.
Yes but I forgot all about them. Looks like I was making that way harder than it had to be.
