java – 使用BufferedImages获取图像的每个像素的颜色

int[] pixels;
BufferedImage image;

image = ImageIO.read(this.getClass.getResources("image.png");
int[] pixels = ((DataBufferInt)image.getRaster().getDataBuffer()).getData();

那正确吗？我甚至无法检查“像素”数组包含什么,因为我得到以下错误：

java.awt.image.DataBufferByte cannot be cast to java.awt.image.DataBufferInt

我只是希望得到阵列中每个像素的颜色,我该如何实现呢？

import java.io.*;
import java.awt.*;
import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;

public class GetPixelColor
{
  public static void main(String args[]) throws IOException{
  File file= new File("your_file.jpg");
  BufferedImage image = ImageIO.read(file);
  // Getting pixel color by position x and y 
  int clr=  image.getRGB(x,y); 
  int  red   = (clr & 0x00ff0000) >> 16;
  int  green = (clr & 0x0000ff00) >> 8;
  int  blue  =  clr & 0x000000ff;
  System.out.println("Red Color value = "+ red);
  System.out.println("Green Color value = "+ green);
  System.out.println("Blue Color value = "+ blue);
  }
}

当然你必须为所有像素添加一个for循环
