ActionScript 3.0 :: Put In A Background Image And A Table It Automatically Creates 2 Pages Instead Of Just Layering The Object

Has anybody messed with PurePDF. I'm trying to set up a SWC library for it and I've gotten stuck on the layering part. If you just put in a background image and a table it automatically creates 2 pages instead of just layering the object. They have a function for layering object but the only tutorial out there is showing how to layer rectangle graphics. Here's my code.

if(layerContent[i] == PdfContentByte)
{
trace('Is PdfContentByte');

XTC_cb.add( layerContent[i] );
}

if works up untill that point but it doesn't recognize a table or an embedded image as a PdfContentByte and that's all it will let you add to the layering list.
