pdfImportEncryptionSettings

BOOL32 __stdcall pdfImportEncryptionSettings(PPDF IPDF);

function pdfImportEncryptionSettings(const IPDF: PPDF): LongBool; stdcall;

Purpose. Carry the currently-open import source's encryption permission flags forward onto the live document being written — not a full settings clone.

Description. Success is defined as "the import file is open", independent of whether the import source is actually encrypted at all — calling this on an unencrypted import source still returns True (a real permission copy of 0/unrestricted, effectively a no-op in that case). The real work (ImportEncryptionSettings) exits early (Result := False, contradicting the wrapper's own "import open = success" framing at the Pascal-method level, though the wrapper itself doesn't propagate this inner False) if the source isn't encrypted; otherwise it copies the source's permission bits and calls SetEncryption(klAES128, '', '', Perms) — always AES-128 with empty open/owner passwords, never the source's actual algorithm or passwords, because (per an inline comment) "passwords cannot be recovered from the source /Encrypt dict." A caller expecting a faithful clone of the source's encryption (same key length, same passwords) will not get one — only the permission restrictions transfer.

Parameters.

Return value. True if an import file is open (regardless of whether it was actually encrypted or whether permissions were actually copied — the wrapper's success signal is looser than the underlying method's).
