Java实现图片与二进制的互相转换

本文实例为大家分享了java将图片转二进制再将二进制转成图片，供大家参考，具体内容如下

import java.awt.image.bufferedimage;  
import java.io.bytearrayinputstream;  
import java.io.bytearrayoutputstream;  
import java.io.file;  
import java.io.ioexception;  
 
import javax.imageio.imageio;  
 
import sun.misc.base64decoder;  
import sun.misc.base64encoder;  
 
public class testimagebinary {  
  static base64encoder encoder = new sun.misc.base64encoder();  
  static base64decoder decoder = new sun.misc.base64decoder();  
    
  public static void main(string[] args) {  
    system.out.println(getimagebinary());  
      
    base64stringtoimage(getimagebinary());  
  }  
    
  static string getimagebinary(){  
    file f = new file("c://20090709442.jpg");     
    bufferedimage bi;  
    try {  
      bi = imageio.read(f);  
      bytearrayoutputstream baos = new bytearrayoutputstream();  
      imageio.write(bi, "jpg", baos);  
      byte[] bytes = baos.tobytearray();  
        
      return encoder.encodebuffer(bytes).trim();  
    } catch (ioexception e) {  
      e.printstacktrace();  
    }  
    return null;  
  }  
    
  static void base64stringtoimage(string base64string){  
    try {  
      byte[] bytes1 = decoder.decodebuffer(base64string);  
        
      bytearrayinputstream bais = new bytearrayinputstream(bytes1);  
      bufferedimage bi1 =imageio.read(bais);  
      file w2 = new file("c://qq.bmp");//可以是jpg,png,gif格式  
      imageio.write(bi1, "jpg", w2);//不管输出什么格式图片，此处不需改动  
    } catch (ioexception e) {  
      e.printstacktrace();  
    }  
  }  
 
}
