Java 中如何转换 Byte[] 为 BufferedImage

程序语言 Java

需要将 byte[] 转换为 BufferedImage， 我们需要使用 InputStream 和 ImageIO.read， 使用方法如下：InputStream in = new ByteArrayInputStream(imageInByte); BufferedImage bImageFromConvert = ImageIO.read(in);可以参考完整的转换函数：[code]package com.mkyong.image;

import java.awt.image.BufferedImage;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import javax.imageio.ImageIO;

public class ImageTest {

public static void main(String[] args) {

	try {

		byte[] imageInByte;
		BufferedImage originalImage = ImageIO.read(new File(
				"c:/darksouls.jpg"));

		// convert BufferedImage to byte array
		ByteArrayOutputStream baos = new ByteArrayOutputStream();
		ImageIO.write(originalImage, "jpg", baos);
		baos.flush();
		imageInByte = baos.toByteArray();
		baos.close();

		// convert byte array back to BufferedImage
		InputStream in = new ByteArrayInputStream(imageInByte);
		BufferedImage bImageFromConvert = ImageIO.read(in);

		ImageIO.write(bImageFromConvert, "jpg", new File(
				"c:/new-darksouls.jpg"));

	} catch (IOException e) {
		System.out.println(e.getMessage());
	}
}

}[/code]
