我有一个对象类,在这个类中我有一个render方法。我想知道如何渲染图像。
我已经搜索了网络,但它是如此模糊,我对编码很新,所以这就是我最终要求的原因。

如果您使用的是JFrame,请将此JPanel添加到您的框架中:
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Image;
import javax.imageio.ImageIO;
import java.io.IOException;
import javax.swing.JPanel;
public class ImageView extends JPanel{
private static final long serialVersionUID = 1L;
private Image img;
private int x = 0;
private int y = 0;
private int width = this.getWidth();
private int height = this.getHeight();
public ImageView(){
super();
try{
img = ImageIO.read(new File("<img_path>.jpg"));
}catch(IOException ex){
// catch exception
}
}
@Override
public void paintComponent(Graphics g){
super.paintComponent(g);
Graphics2D g2d = (Graphics2D) g;
if(img!=null){
g2d.drawImage(img, x, y, width, height, this);
}
}
// your render method
public void render(Image img){
this.img = img;
repaint();
}
}
