Frequently Asked Questions

Q) Does PDF/raster support multiple pages in a single file?
A) Yes, but that is not its priority

Q) Can PDF/raster support encryption or authentication?
A) PDF/raster supports password and certificate encryption and multiple digital signatures

Q) What IP restrictions are there in PDF/raster?
A) None – it is a strict subset of the PDF specification, open sourced by Adobe

Q) Can regular PDF libraries be used to read PDF/raster?
A) Yes

Q) How does one identify a PDF/raster file?
A) A PDF/raster file is a well-formed PDF file, but has a comment section in its trailer with an identifying string which indicates to a reader that it conforms to the PDF/raster subset of the full PDF specification. The intention is that if a PDF/raster file is edited using a conventional PDF library which is naive about PDF/raster, the resulting file will not have this comment as the last object in the file.
