I have a client who wants some PDFs messed with. To do so, layers need to be split and recompiled. Here are links that will help me
- decide which SDK to use
- how to … well … do it.
- A good discussion of pdf libraries
- layers or content streams
- extract layers
- http://www.soft-xpansion.eu/files/pdflib/PDF%20Xpansion%20SDK%20Guide.pdf
- foxxit, sdk documentation
- PDFtron
- pdf creation
- opensource
- separate into text and other
- a good article steering the way
- pdfkit – a nodejs sdk to MAKE pdfs
- pdffill, pdf.wondershare (pdffill object remover)
