Description Reggie Carey 2008-10-16 04:43:44 UTC
The following code snippet will cause exceptions and errors on many powerpoint documents and will generally result in corrupted file output:

Exception handling, imports removed for clarity.

public class TestPowerPoint

 public static void main(String[] args)
  new TestPowerPoint(args[0]);

 public TestPowerPoint(String fileToTest)
  SlideShow ppt = new SlideShow(new FileInputStream(fileToTest));
  for (Slide slide : ppt.getSlides())
   for (TextRun textRun : slide.getTextRuns())
    for (RichTextRun richTextRun : textRun.getRichTextRuns())
    String text = richTextRun.getText();
  ppt.write(new FileOutputStream("new"+fileToTest));

Please attach the template ppt. Without it, it's hard to tell what is wrong.

We did not get the necessary PPT attachment for a long time, thus resolving this for now.
