java Execl 不支持 写入png 解决

log.error("图片写入Execl 开始 {}", " 路径：" + imgPath);
            BufferedImage bufferedImage = ImageIO.read(new File(imgPath));
            // 将BufferedImage转换为JPEG
            ByteArrayOutputStream jpegStream = new ByteArrayOutputStream();
            ImageIO.write(bufferedImage, "jpeg", jpegStream);
            byte[] pictureData = jpegStream.toByteArray();
            log.error("图片写入Execl 正常：{}", " 路径：" + imgPath + "byte:" + pictureData.toString());
            CreationHelper helper = workbook.getCreationHelper();
            Drawing<?> drawing = sheet.createDrawingPatriarch();
            ClientAnchor anchor = helper.createClientAnchor();
            anchor.setCol1(col); // 起始列
            anchor.setRow1(row); // 起始行
            anchor.setCol2(col); // 结束列
            anchor.setRow2(row); // 结束行
            Picture picture = drawing.createPicture(anchor, workbook.addPicture(pictureData, Workbook.PICTURE_TYPE_JPEG));
            picture.resize(1, 1);

把图片转成jpeg 写入Execl    

有其他办法的话   求告知
