谁会用jacob把多页ppt转换成pdf

[嬲哥有个小明妃]

用的jacob_1.9。看了网上挺多回答都只有直接把ppt转化成pdf的，现在想把几页ppt同时放在一页PDF上不知道怎么弄。

private static boolean ppt2PDF(String inputFile, String pdfFile) {
        try {
            ActiveXComponent app = new ActiveXComponent(
                    "PowerPoint.Application");
            // app.setProperty("Visible", msofalse);
            Dispatch ppts = app.getProperty("Presentations").toDispatch();

            Dispatch ppt = Dispatch.call(ppts, "Open", inputFile, true,// ReadOnly
                    true,false).toDispatch();

            Dispatch.call(ppt, "SaveAs", pdfFile, ppSaveAsPDF);

            Dispatch.call(ppt, "Close");

            app.invoke("Quit");
            return true;
        } catch (Exception e) {
            return false;
        }
    }
