java - java中的Tiff文件压缩

Question

如何在 java 中压缩 tiff 文件，当我将 jpeg 文件添加到 tiff 时，文件大小在增加

File f2 = new File("D:/KYCDATA/mani/myimage_compressed.jpeg");

    BufferedImage image3 = ImageIO.read(f2);
    List<BufferedImage> list = new ArrayList<BufferedImage>();
    list.add(image3);

    File tiffFile = new File("D:/KYCDATA/mani/mani.tiff");
    if(tiffFile.exists()) {
        tiffFile.delete();
    }
    ImageOutputStream ios = null;
    ImageWriter writer = null;
    Iterator it = ImageIO.getImageWritersByFormatName("tiff");
    if (it.hasNext()) {
        writer = (ImageWriter) it.next();
    }

    ios = ImageIO.createImageOutputStream(tiffFile);
    writer.setOutput(ios);

    IIOImage iioImage = null;
    for (int i = 0; i < list.size(); i++) {
        iioImage = new IIOImage(list.get(i), null, null);
        if (i == 0) {
            writer.write(iioImage);
        } else {
            writer.writeInsert(i, iioImage, null);
        }
        writer.endWriteSequence();

TIFF 使用无损压缩，因此如果我正确理解您的问题，我希望 TIFF 比原始 JPEG 大。请参阅此处以获得简单说明:
