我正在使用apachefoo将ppt转换为图像。但是，表格图像未保存

public static void main(String[] args) throws Exception{

                        imgFilePathList.add(slideFilePath);

                        File slideFile = new File(slideFilePath);

                            slideFile.getParentFile().mkdirs();
                        }

                        ImageIO.write(img, "jpg", slideFile);
                    }

                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } finally {
                    if (fis != null) {
                        fis.close();
                    }
                }
