Writing and file structure

FileStructure

The file's header, body, root and trailer additions (7.5).

FileWriter

Stateful serialization belongs to a per-call context, separate from the file model.

IncrementalWriter

Append a delta while preserving every byte and reference identity of previous revisions (7.5.6).

LinearizedWriter

Native Annex F layout and binary hints; no external linearization program is invoked.

PdfFileOutput

Filesystem output policy shared by complete files and frozen revisions.

SerializationContext

An identity map and serialization guard scoped to one PDF file.

SerializesPdf

FileBody

FileHeader

FileRevision

Frozen serialized bytes and document-scoped reference bindings; this is not a PDF parser.

FileTrailer

FreeListDelta

Explicit changed historical free entries; new unused holes remain the section builder's responsibility.

FreeListState

Complete effective type-0 entries, excluding hybrid compatibility shadows of live objects (7.5.4, PDF p49).

GeneratedRevisionTimeline

Explicit immutable ancestry of bytes generated by the native writers; not parsed external history.

HybridCrossReferenceSection

Prior classic fallback and current update table, ISO7.5.8.4; hidden generations cannot be reused.

HybridReferenceObjects

Preserve logical identities while omitting required legacy-visible members from physical object-stream copies.

HybridVisibleGraph

Conservative legacy-visible closure, ISO7.5.8.4, PDF page60; resources and complete font graphs stay visible.

IncrementalUpdate

ISO 32000-1, 7.5.6: explicitly staged objects appended to a generated revision.

IncrementalVersionPolicy

ISO 32000-2:2020 7.5.6, EC3 issue 399 (Completed), physical PDF page 75.

ObjectByteSpan

Location of an indirect object in bytes produced by this writer; not parsed external data.

ObjectLifecycleTransition

One immutable release/reuse plan over a known generated revision (7.3.9/7.5.4/7.5.7).

ObjectStream

A real object stream with byte offsets and generation-zero members (7.5.7).

ObjectStreamEntry

A generation-zero indirect object packed into an ObjStm (7.5.7).

PdfVersion

Supported output declarations (ISO_32000-2_sponsored_EC3.pdf, 7.5.2, PDF pp. 69–70).

ReleaseIndirectObject

Delete exactly one currently live generation (7.5.4/7.5.6), retaining its original physical bytes.

RetiredObjectGeneration

Frozen tombstone: aliases keep this obsolete generation and never become aliases of a reused value.

ReuseObjectNumber

Select a free number for a distinct ordinary value; its generation comes from the effective free entry.

RevisionObject

An effective indirect value and the PHP identities that refer to its frozen revision.

RevisionReference

The identifier actually emitted for this exact construction-reference instance.

RevisionStreamSnapshot

Actual encoded plaintext emitted once, with the exact final dictionary frozen before serialization.

RevisionValueSnapshot

Freeze direct containers while preserving explicit indirect identities across revisions.

SerializedRevisionValue

The effective serialized value, distinct from the construction identity retained by its aliases.

EmbeddedFileHintGroup

Table F.12, physical PDF page 702; shared-only groups explicitly use zero length/count.

EmbeddedFileHintTable

Tables F.11/F.12, physical PDF page 702.

ExtendedGenericHintTable

Table F.10, physical PDF page 701: generic group plus shared-table indices.

FixedWidthOffset

A direct integer whose ten-byte spelling keeps two-pass layout stable.

GenericHintTable

Table F.9, physical PDF page 701: one contiguous document-level object group.

HintBitStream

Document-local binary builder; item vectors are padded to byte boundaries.

HintBitWidth

Exact integer width, including a zero-bit field for the value zero.

HintField

One unsigned field in an Annex F.4 high-order-bit-first hint table.

HintStreamExtent

Whole indirect-object extent of an overflow hint stream, Table F.1 /H (PDF page 688).

HintStreamSplit

Explicit decoded-byte boundary; it may divide a hint header or a packed item vector.

HintTableEntry

An additional standard hint table and its explicit stream dictionary key.

LinearizationCrossReferenceStream

Annex F.3.1/F.3.11, one uncompressed xref stream with fixed W=[1 4 2].

LinearizationCrossReferenceTable

One consecutive Annex F subsection; only the main subsection includes free object zero.

LinearizationHybridMainTable

Single main subsection: physical objects are live; highest compressed IDs stay permanently hidden from old readers.

LinearizationLayout

Physical sections and compressed logical members, explicitly separated as required by F.3.1.

LinearizationLimits

Explicit capacity for the uncompressed Annex F writer and 32-bit hint fields.

LinearizationParameters

Table F.1, physical PDF page 688. Fixed-width offsets allow exact two-pass layout.

LinearizationPlan

One graph's Annex F.3 ordering. No input page, reference or dictionary is mutated.

LinearizationSecurity

Initial-file security boundary; hint streams use normal stream encryption (F.4, PDF page 694).

LinearizedObjectStream

A re-numbered member's container; headers use the current logical identity, never its old number.

ObjectIdentifierRemapping

Explicit permission to renumber a whole, newly serialized object graph.

PrimaryHintStream

Table F.2: page offsets at zero, followed by shared and named hint tables.

SharedObjectGroup

Table F.6, physical PDF pages 698–699. A signature is an optional MD5 resource hint.

SharedObjectHintTable

SharedObjectReference

An index in the shared-object hint table, not an indirect object number.

ThumbnailDictionaryCopy

Output-only dictionary with actual copied reference targets; lazy entries support indirect cycles.

ThumbnailFilterCopy

Encoding is unchanged; decoding parameters use the output thumbnail dependency graph.

ThumbnailGraphCopies

Per-plan lazy copies: indirect cycles retain actual object-valued targets and source identities remain untouched.

Explicit permission for output-only thumbnail value copies required by F.3.10/F.4.3.

ThumbnailHint

One thumbnail image group, associated with its document page index.

ThumbnailHintTable

Tables F.7/F.8, physical PDF pages 699–700. Entries follow logical page order.
