HPDFVisitContentStreamOperators

Visits a decoded content stream and returns validated transformed bytes

Declaration

function HPDFVisitContentStreamOperators(const Bytes: TBytes;
  Sender: TObject; const Visitor: IHPDFContentOperatorVisitor;
  OnOperator: THPDFContentOperatorEvent;
  const Options: THPDFContentOperatorVisitOptions;
  CancellationToken: THPDFCancellationToken; out Output: TBytes;
  out Statistics: THPDFContentOperatorVisitStatistics): boolean;

Parameters

• Bytes contains decoded PDF content-stream bytes
• Sender is forwarded to the Delphi event callback
• Visitor and OnOperator are optional synchronous handlers
• Options supplies all parser and replacement budgets
• CancellationToken enables cooperative cancellation
• Output receives byte-identical input when no edits are requested
• Statistics receives status, counts, state depths, byte totals, and diagnostics

Return value

True for completed or intentionally stopped traversal with valid output, otherwise False

Usage notes

• The interface visitor runs before the event callback
• Replacement output is reparsed before success when ValidateOutput=True
• Rejection and failure clear Output so callers cannot publish partial edits
