function pdfNewPostScriptXObjectA(const IPDF: PPDF; PS: PAnsiChar): Integer; stdcall;
function pdfNewPostScriptXObjectW(const IPDF: PPDF; PS: PWideChar): Integer; stdcall;
function pdfDrawPostScriptXObject(const IPDF: PPDF; PSRef: Integer): Integer; stdcall;

Purpose. Register a PostScript XObject (/Subtype /PS, a legacy PDF mechanism for embedding a PostScript calculator/language fallback) and draw it onto the current page.

Description. pdfDrawPostScriptXObject is a confirmed no-op beyond bookkeeping validation. pdfNewPostScriptXObjectA/W do genuinely store the PostScript source text (NewPSXObjectH, into an internal array, returning a real 1-based handle) — but pdfDrawPostScriptXObject's entire implementation is a range check only (Result := (PSRef >= 1) and (PSRef <= FPSXCount)): it never writes a /PS XObject reference into the page's content stream or resource dictionary, and the stored PostScript source is never serialized into the output PDF at all. Calling this pair produces no visible or embedded effect on the output document beyond the initial in-memory registration.

Parameters.

Return value. pdfNewPostScriptXObject: the new (inert) handle; 0 if IPDF is invalid. pdfDrawPostScriptXObject: 1 if PSRef is in range; 0 otherwise — does not indicate anything was drawn.
