All coordinates inside a Form XObject are relative to that XObject – not to the 
primary PDF.

Subject: [Podofo-users] Question about Nested XObjects and Images

Does anybody have experience with rendering nested XObjects (forms), containing 
an Image xobject(s)? My problem is the positioning of the images. This is the 
scenario

Fm28 contains Fm0 which contains Image Im0.
All form matrices are set to 1 0 0 1 0 0

Im0 is renderer in it's original defined position, not within the BBox of the 
form it has been referenced.

What rules need to be implemented to render the image in the correct location? 
I cannot find information regarding the positioning of the nested forms. When I 
render the BBox of each form, it is in the correct position.
