function pdfAddSVGAnnotationFromFileA(const IPDF: PPDF; Left, Top, Width, Height: Double; FileName: PAnsiChar; Options: Integer): Integer; stdcall;

Purpose. Embed an SVG file (rendered directly to the page) or a SWF (Flash) file (attached as an embedded file behind a /Screen annotation) at a given rectangle.

Description. Architecturally important: pdfAddSVGAnnotationFromFile does not create a self-rendering annotation — it draws the SVG content directly into the current page's content stream at load time (DrawSVG), and *separately* registers a Square annotation with an invisible border (/BS /W 0) and the literal placeholder text "SVG" as /Contents — the annotation exists as a marker/anchor (e.g. for later hit-testing or metadata), not as the thing that actually displays the SVG; the visible rendering is baked into the page itself and would persist even if the marker annotation were later deleted. pdfAddSWFAnnotationFromFile is a real, standard-conforming multimedia embed: attaches the SWF bytes as a document embedded file (AttachFileBuf) and registers a /Screen-subtype annotation carrying the title — actually playing the SWF at view time is the responsibility of the viewer/reader's own multimedia handler, not this SDK, per the normal PDF /Screen annotation contract. Both wrappers accept Options but neither passes it through to the real creation methods — it has no observable effect.

Parameters.

Return value. The new annotation's handle; 0 if the file doesn't exist/is empty, or no page is currently open.
