function SaveAs(Stream: TStream; Option: TSaveOption = saNone; PdfVersion: TPdfVersion = pvUnknown): Boolean;
| Stream | TStream value that receives the PDF data |
| Option | TSaveOption. Save option: saNone for a normal save, saIncremental for an incremental update, saNoIncremental to force a full rewrite, or saRemoveSecurity to remove security while saving |
| PdfVersion | TPdfVersion target; use pvUnknown to preserve the current version |
function SaveAs(const FileName: string; Option: TSaveOption = saNone; PdfVersion: TPdfVersion = pvUnknown): Boolean;
| FileName | string. The output file path. A sibling temporary file is completed first, then atomically replaces the destination |
| Option | TSaveOption. Save option: saNone, saIncremental, saNoIncremental, or saRemoveSecurity |
| PdfVersion | TPdfVersion target; use pvUnknown to preserve the current version |
True if the document was saved successfully, or False on failureSaves the current document to a file path or a TStream
The PdfVersion parameter specifies the output PDF version;
pass pvUnknown to keep the document's existing version
The Compressed property controls stream compression. Hybrid-reference, xref-stream and object-stream inputs are preserved when a classic-xref rewrite cannot retain their complete cross-reference semantics
Explicit PDF-version checks follow the active cross-reference revision chain and active object-stream members, so stale or unreferenced object bodies do not affect the requested version gate
The file overload leaves an existing destination unchanged if compression, post-processing or version validation fails
