THotPDF.VisitLoadedPageContentOperators

Bezoekt gedecodeerde paginaoperaties en commit optioneel gevalideerde bewerkingen

Declaratie

function VisitLoadedPageContentOperators(PageIndex: Integer;
  ApplyChanges: boolean;
  const Options: THPDFContentOperatorVisitOptions;
  CancellationToken: THPDFCancellationToken;
  out Statistics: THPDFContentOperatorVisitStatistics): boolean;

Parameters

PageIndex selecteert een geladen pagina met nulbasis
ApplyChanges commit geldige verwijder- en vervangacties wanneer True
Options definieert parser- en vervangingsbudgetten
CancellationToken kan nil zijn
Statistics receives traversal and transformation results

Retourwaarde

True when traversal completes or stops intentionally with valid output, otherwise False

Gebruiksopmerkingen

The shorter overload uses THPDFContentOperatorVisitOptions.Default and no cancellation token
ApplyChanges=False supports inspection, measurement, and policy checks without changing the document
No page mutation occurs until callbacks finish and the complete output passes validation
A successful mutation replaces multiple content segments with one decoded indirect stream and invalidates all page render caches
