如何将BufferedImage实例嫖狟MP文件

Answer 1

保存为png、jpg之类的倒是很简单的

Java code?

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;

public class Demo {

public static void main(String[] args) {
int w=400;
BufferedImage im=new BufferedImage(w, w, BufferedImage.TYPE_INT_ARGB);
for(int i=0;i<w;i++){
for(int j=0;j<w;j++){
int m=(int)Math.sqrt((i*j+i*i+j*j))%256;
int rgb=(m<<16)+(m<<8)+(m)+(0xff000000);
//System.out.println(Integer.toHexString(rgb));
im.setRGB(i, j, rgb);
}
}
File f=new File("D:/test.png");
try {
ImageIO.write(im, "png",f);
im.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
