  • java--照片和BYTE这些东西阵列

    使用java,图像被变换成BYTE排列、和该阵列为图象,远程传输的图片进行

    参考:http://blog.csdn.net/huang9012/article/details/18241539


    代码例如以下:

    package com.third.demo;
    
    import java.io.ByteArrayOutputStream;
    import java.io.File;
    
    import javax.imageio.stream.FileImageInputStream;
    import javax.imageio.stream.FileImageOutputStream;
    
    import org.json.JSONObject;
    
    public class CreatUploadJson {
    
    	public static void buildJson() throws Exception {
    		// 图片转换成 BYTE数组
    		byte[] data = null;
    		FileImageInputStream input = new FileImageInputStream(new File("d://7.jpg"));
    		ByteArrayOutputStream output = new ByteArrayOutputStream();
    		byte[] buf = new byte[1024];
    		int numBytesRead = 0;
    		while ((numBytesRead = input.read(buf)) != -1) {
    			output.write(buf, 0, numBytesRead);
    		}
    		data = output.toByteArray();
    		output.close();
    		input.close();
    
    //		JSONObject jo = new JSONObject();
    //		jo.put("agentId", "001");
    //		jo.put("picType", "1");
    //		jo.put("picName", "素材名称");
    //		jo.put("picByte", data);
    //		
    //		System.out.println(jo.toString());
    		
    		// byte数组 转换成 图片
    		FileImageOutputStream imageOutput = new FileImageOutputStream(new File("e://1.jpg"));
    	    imageOutput.write(data, 0, data.length);
    	    imageOutput.close();
    	}
    
    	/**
    	 * @param args
    	 */
    	public static void main(String[] args) {
    		try {
    			buildJson();
    		} catch (Exception e) {
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		}
    
    	}
    
    }
