function pdfSaveImageListItemDataToFileA(const IPDF: PPDF; ImageListID, ImageIndex, Options: Integer; ImageFileName: PAnsiChar): Integer; stdcall;
function pdfSaveImageListItemDataToFileW(const IPDF: PPDF; ImageListID, ImageIndex, Options: Integer; ImageFileName: PWideChar): Integer; stdcall;

Purpose. Write a specific, directly-addressed image (by index) to a file — the one function in this cluster that does not rely on either of the two implicit "current image" conventions above.

Description. Both ImageListID and Options are accepted by the ABI but never read — the implementation resolves the target purely by ImageIndex (passed straight through to the same underlying SaveImageIdxToFile helper pdfSaveImageToFile uses, but here with an explicit index rather than the selection cursor) and writes the same raw encoded bytes as pdfSaveImageToFile. ImageListID's name implies this SDK might expose multiple independent per-context image lists (e.g. one per import session), but in fact there is only ever the single document- wide FImages array — the parameter has nothing to select between. Options similarly implies configurable output behavior (format conversion, quality, etc.) that does not exist — the bytes are always written verbatim, unmodified.

Parameters.

Return value. Non-zero on success; 0 if ImageIndex is out of range or the write failed.
