I was wondering if the following problem has an issue :
If you have a PDF file with several layers (OCG in QuickPDF language), and you delete one of them. Then the objects (like images) related to the OCG are still present ! Confused

When you use Illustrator, our any other image program, when you delete a layer, you would like that all the related images to also get deleted.

Thus I was wondering :
- How is it possible to know which OCG are related to which objects ?
- Perhaps the reverse is also possible, but we would have to parse all the objects (images, text, line, ...) to determine to which OCG they are related to...
