THPDFContentSemanticStatistics Record

Collects normalized operation counts, state depth, and canonical byte size computed for one content stream

Declaration

THPDFContentSemanticStatistics= record
  TokenCount: Integer;
  OperationCount: Integer;
  StateOperationCount: Integer;
  RedundantStateOperationCount: Integer;
  NormalizedEventCount: Integer;
  MaximumGraphicsStateDepth: Integer;
  CanonicalBytes: Int64;
  ErrorOffset: Integer;
  LimitExceeded: boolean;
  Valid: boolean;
  Diagnostic: AnsiString;
end;

HPDFContentStream

Fields

Field	Purpose
`TokenCount`	Tokens parsed from the stream
`OperationCount`	Operators found in the stream
`StateOperationCount`	Graphics state operators tracked during normalization
`RedundantStateOperationCount`	State operations that did not change the canonical state
`NormalizedEventCount`	Events in the canonical event sequence
`MaximumGraphicsStateDepth`	Deepest graphics state nesting reached while interpreting
`CanonicalBytes`	Size of the canonical byte form produced for comparison
`ErrorOffset`	Byte offset where parsing or evaluation failed
`LimitExceeded`	True when the operation or canonical byte limit stopped the pass
`Valid`	False when parsing or evaluation failed
`Diagnostic`	Failure description when `Valid` is False

Usage notes

Filled by HPDFNormalizeContentStreamGraphicsState alongside the canonical byte output
RedundantStateOperationCount quantifies state noise that normalization removes before comparing streams
Compare two streams through HPDFCompareContentStreamsSemantic rather than comparing these records field by field
