我在将png转换为tiff时遇到问题.转换很顺利,但图像很大.我认为问题是我没有正确进行压缩？任何人都有任何建议？

这是代码示例

public static void test() throws IOException {

    // String fileName = "4958813_1";
    String fileName = "4848970_1";
    String inFileType = ".PNG";
    String outFileType = ".TIFF";

    ImageIO.scanForPlugins();

    File fInputFile = new File("I:/HPF/UU/" + fileName + inFileType);
    InputStream fis = new BufferedInputStream(new FileInputStream(
            fInputFile));
    PNGImageReaderSpi spi = new PNGImageReaderSpi();
    ImageReader reader = spi.createReaderInstance();

    ImageInputStream iis = ImageIO.createImageInputStream(fis);
    reader.setInput(iis, true);
    BufferedImage bi = reader.read(0);

    TIFFImageWriterSpi tiffspi = new TIFFImageWriterSpi();
    ImageWriter writer = tiffspi.createWriterInstance();
    //Iterator<ImageWriter> iter =  ImageIO.getImageWritersByFormatName("TIFF");
    //ImageWriter writer = iter.next();

    ImageWriteParam …
