 8             $ppt = new \COM("powerpoint.application") or die("Unable to instantiate Powerpoint");
 9             $presentation = $ppt->Presentations->Open($srcfilename, false, false, false);
10             $presentation->SaveAs($destfilename,32,1);
11             $presentation->Close();
12             $ppt->Quit();
13         } catch (\Exception $e) {
14             if (method_exists($ppt, "Quit")){
15                 $ppt->Quit();

17             return;

17                 17,                         // wdExportFormatPDF

20                 3,                          // wdExportFromTo
21                 1,                          // begin page

26                 1                           // WdExportCreateBookmarks
27             );
28             $word->ActiveDocument->Close();
29             $word->Quit();
30         } catch (\Exception $e) {
31             if (method_exists($word, "Quit")){
32                 $word->Quit();
33             }
34             return;
