※ 部份環境中文字會有亂碼產生，故_html.getBytes() =>  _html.getBytes("UTF-8") 排除

※ 部份環境無法讀取TTC 選TTF字型檔可以排除

// PDF設定縮放

PdfDestination pdfDest = new PdfDestination(PdfDestination.XYZ, 0, document.getPageSize().getHeight(), 0.8f);

PdfAction action = PdfAction.gotoLocalPage(1, pdfDest, pdfWriter);

pdfWriter.setOpenAction(action);
