Package com.pd4ml.pdf.cos.writer

Class COSDocumentWriter

  • public final class COSDocumentWriter
extends java.lang.Object
    Serializes a whole COSDocument built up in memory (e.g. by com.pd4ml.pdf.merge) into a complete, self-contained PDF file: header, every registered indirect object, a classic xref table, and a trailer -- as opposed to COSWriter (one object's syntax only) or IncrementalUpdateWriter (an update appended to one specific original document's original bytes).

    The document's objects are expected to have been allocated with contiguous object numbers starting at 1 (which is what every allocator in COSObjectImporter guarantees); any gap is still handled (written as a free xref entry) but is not something this writer's own callers are expected to produce.
