CopyIndirect(PrIndirectReference)

Translate a PRIndirectReference to a PdfIndirectReference In addition, translates the object numbers, and copies the referenced object to the output file. NB: PRIndirectReferences (and PRIndirectObjects) really need to know what file they came from, because each file has its own namespace. The translation we do from their namespace to ours is at best heuristic, and guaranteed to fail under some circumstances.

Parameters

inp PrIndirectReference

Returns

PdfIndirectReference

CopyObject(PdfObject)

Translate a PR-object to a Pdf-object

protected PdfObject CopyObject(PdfObject inp)
