ReaderOptions

Optional maximum input size in bytes enforced by OfficeDocumentReader when reading from a file or seekable stream. When null, a registered format handler may apply its documented default; otherwise no size limit is enforced.

OpenXML security: maximum characters allowed per part when opening OpenXML packages (best-effort). When null, the OpenXML SDK default is used.

OpenXML security: maximum image asset entries emitted from an Office package. When null, no image asset entry limit is enforced.

Optional password used to open encrypted Office files when the selected reader engine supports decryption.

OpenXML security: maximum placements emitted for one image relationship. When null, no per-relationship placement limit is enforced.

OpenXML security: maximum bytes read from a single image part. When null, no individual image payload limit is enforced.

OpenXML security: maximum unique image payload bytes retained while extracting assets. Repeated placements of the same image part count once toward this limit. When null, no total image payload limit is enforced.

Maximum characters per emitted chunk (best-effort).
