OutputFilename

Filename to which the pdf should be written to.

Set

MemoryOutputCallback

Address of a callback function which retrieves the pdf data. The address has to be written as a string, which contains the address as normal number. The callback function needs to have the signature:

int MemoryCallback(const uint8_t* output, size_t length, void* userdata, int error);

• output contains some data of the pdf file to write.
• length defines the length of the data
• userdata is the object, defined inside MemoryOutputUserdata
• error defines, if there was an error during execution, otherwise 0.

The return value needs to be 1, if the callback wan’t to return success, otherwise 0.

Set

MemoryOutputUserdata

Address of a userdata object which is used inside the callback. The address has to be written as a string, which contains the address as normal number.

DontOverwriteProducer

Don’t write the CIB pdfModule default Producer into the Metadata.

Set

WritingMode

• ObjectAndXrefStream: use object and xref streams
• XrefStream: use only xref streams
• Xref: use only standard xref
• Best: use the best algorithm for the used PDF version (default)

Set

IncrementalUpdate

• 0: Deactivated (default)
• 1: Activated always
• Auto: Activated only, when signed Signature fields already exits in the PDF document

An incremental update to a PDF means, that the whole input document is not changed in its content, but at the end of the document all changes, which were made are written combined inside an update entry. This means e.g. that signed signatures in an existing PDF document are not getting broken, but still you can add more content or modify the PDF document. Inside a (good) PDF viewer you can see then, that the PDF consists of different versions and you can switch between them.
