无法使用 Java ImageIO 标准库读写 TIFF 图像文件

Question

I don't know what to do with TIFF images, but I can't read or write any of them using straight Java standard ImageIO library. Any thoughts?

Thanks.

Answer 1

If you don't like or can't use JAI for any reason I have written a TIFF ImageReader plugin for ImageIO, available on GitHub . It is pure Java and does not need any native installs, and comes with a very friendly open source license (BSD).

It supports any baseline TIFF option, along with a lot of standard extensions. From version 3.1 the TIFF plugin also has write support.

With the proper JARs in your class path, usage can be as simple as:

BufferedImage image = ImageIO.read(inputTIFF);
// ...modify image (compose, resize, sharpen, etc)...
ImageIO.write(image, "TIFF", outputTIFF);

Answer 2

According to JEP 262: TIFF Image I/O the TIFF plugin that used to be part of JAI will be available as part of the Java SE, starting from Java 9.

That means, using Java 9 or later, the following code will just work, without any extra imports or dependencies:

BufferedImage image = ImageIO.read(inputTIFF);
// ...modify image (compose, resize, sharpen, etc)...
ImageIO.write(image, "TIFF", outputTIFF);

---

I haven't yet been able to verify the support for non-baseline TIFF flavors in this plugin, but I assume at least baseline TIFFs should be fully supported.

I tried JAI, and it didn't work for me.

Where are you stuck? Does the following work for you?

import java.io.File;
import java.io.FileOutputStream;
import java.awt.image.RenderedImage;
import com.sun.image.codec.jpeg.JPEGCodec;
import com.sun.image.codec.jpeg.JPEGImageEncoder;
import javax.media.jai.NullOpImage;
import javax.media.jai.OpImage;
import com.sun.media.jai.codec.SeekableStream;
import com.sun.media.jai.codec.FileSeekableStream;
import com.sun.media.jai.codec.TIFFDecodeParam;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageCodec;

public class Main {
    public static void main(String args[]) {
        File file = new File("input.tif");
        try {
            SeekableStream s = new FileSeekableStream(file);
            TIFFDecodeParam param = null;
            ImageDecoder dec = ImageCodec.createImageDecoder("tiff", s, param);
            RenderedImage op = new NullOpImage(dec.decodeAsRenderedImage(0),
                                               null,
                                               OpImage.OP_IO_BOUND,
                                               null);
            FileOutputStream fos = new FileOutputStream("output.jpg");
            JPEGImageEncoder jpeg = JPEGCodec.createJPEGEncoder(fos);
            jpeg.encode(op.getData());
            fos.close();
        }
        catch (java.io.IOException ioe) {
            System.out.println(ioe);
        } 
    }
}

Java supports TIFF format only from Java 9 release. If you are trying to use ImageIO for TIFF into older Java version it will give you exception.

If you want to use TIFF in earlier version as well, you Twelve Monkey plugin along with Java just by adding dependency of Twelve Monkey.

Maven Dependency for Twelve Monkey:

<dependency>
   <groupId>com.twelvemonkeys.imageio</groupId>
   <artifactId>imageio-tiff</artifactId>
   <version>3.5</version>
</dependency>*

I'm also giving example to merge the multiple images into Single TIFF with pages using Twelve Monkey,

BufferedImage b1 = null;
BufferedImage b2 = null;

TIFFImageReaderSpi SPI = new TIFFImageReaderSpi();

ImageReader imageReader1 = SPI.createReaderInstance();
ImageInputStream iis1 = ImageIO.createImageInputStream(new File("1.tif"));
imageReader1.setInput(iis1);
b1 = imageReader1.read(0); 

ImageReader imageReader2 = SPI.createReaderInstance();
ImageInputStream iis2 = ImageIO.createImageInputStream(new File("2.tif"));
imageReader2.setInput(iis2);
b2 = imageReader2.read(0);

ImageWriter writer = ImageIO.getImageWritersByFormatName("TIFF").next();

writer.setOutput(ImageIO.createImageOutputStream(new File("3.tif")));

ImageWriteParam writeParam = writer.getDefaultWriteParam();
//writeParam.setTilingMode(ImageWriteParam.MODE_EXPLICIT);
//writeParam.setCompressionType("Deflate");

writer.prepareWriteSequence(null);

IIOImage i1 = new IIOImage(b1, null, null);
IIOImage i2 = new IIOImage(b2, null, null);

writer.writeToSequence(i1, writeParam);
writer.writeToSequence(i2, writeParam);

writer.endWriteSequence();
writer.dispose();

The above code will work with Java8 and written to open two TIFF image and merge into single.

Also, you may use compression as needed. Just use comment lines to add compression.

Add Maven dependency :

<dependency>
  <groupId>org.geotoolkit</groupId>
  <artifactId>geotk-coverageio</artifactId>
  <version>3.17</version>
</dependency>

Code example :

import org.geotoolkit.image.io.plugin.RawTiffImageReader;

IIORegistry registry = IIORegistry.getDefaultInstance();   
registry.registerServiceProvider(new RawTiffImageReader.Spi());            

String[] a = ImageIO.getReaderFileSuffixes();    
for (int i=0; i<a.length; i++) {
 System.out.println(a[i]);
}   

BufferedImage image = ImageIO.read(new File("C:\\mypic.tiff"));

ImageIO.write(image, "jpg",new File("C:\\out.jpg"));
ImageIO.write(image, "gif",new File("C:\\out.gif"));
ImageIO.write(image, "png",new File("C:\\out.png"));
ImageIO.write(image, "tif",new File("C:\\out.tiff"));
