function pdfGetLogMetafileSizeA(const IPDF: PPDF; const FileName: PAnsiChar; var R: TRectL): LongBool; stdcall;
function pdfGetLogMetafileSizeW(const IPDF: PPDF; const FileName: PWideChar; var R: TRectL): LongBool; stdcall;
function pdfGetLogMetafileSizeEx(const IPDF: PPDF; Buffer: Pointer; BufSize: Cardinal; var R: TRectL): LongBool; stdcall;

Purpose. Read a metafile's own logical bounds rectangle (its embedded device frame), without inserting it — useful for computing an aspect- correct placement box before calling pdfInsertMetafile.

Description. A/W read the file into memory and delegate to a shared pdfGetLogMetafileSize_File file-reading helper; Ex parses the caller's buffer directly via EMFGetBounds, filling R from the parsed Left/Top/Right/Bottom extents. IPDF is accepted by all three but this is a pure file/buffer-parsing utility, not consulted for any document-specific state — same pattern as pdfGetImageCount's file- scanning variants (Image Objects and Introspection).

Parameters.

Return value. True if the file/buffer parsed as a valid metafile and R was filled; False otherwise.
