检查以下代码以读取PPTX文件中的所有图像：

SlideShow ppt = new SlideShow(new HSLFSlideShow("slideshow.ppt"));

  //extract all pictures contained in the presentation
  PictureData[] pdata = ppt.getPictureData();
  for (int i = 0; i < pdata.length; i++){
    PictureData pict = pdata[i];

    // picture data
    byte[] data = pict.getData();

    int type = pict.getType();
    String ext;
    switch (type){
      case Picture.JPEG: ext=".jpg"; break;
      case Picture.PNG: ext=".png"; break;
      case Picture.WMF: ext=".wmf"; break;
      case Picture.EMF: ext=".emf"; break;
      case Picture.PICT: ext=".pict"; break;
      default: continue;
    }
    FileOutputStream out = new FileOutputStream("pict_"+i + ext);
      out.write(data);
      out.close();

  }
