Layering PDFs

I have a base pdf (a.pdf).

I have another pdf (b.pdf) that needs to be LAYERED on top of a.pdf and allow it to show through.

Then I have a watermark.jp that needs to be added to this whole mess.

How would I do this? Code would be nice.

Thanks

Hi Rollie,


Thanks for contacting support.

As per my understanding, you need to add one PDF was watermark on top of another PDF file. After that, you need to add another image as watermark to the resultant file. Please visit the following links for required information on
