[英]How do I draw an image to a JPanel or JFrame?
How do I draw an Image to a JPanel or JFrame, I have already read oracle's tutorial on this but I can't seem to get it right.如何将图像绘制到 JPanel 或 JFrame,我已经阅读了 oracle 的教程,但我似乎无法正确理解。 I need the image "
BeachRoad.png
" to be displayed on a specific set of coordinates.我需要将图像“
BeachRoad.png
”显示在一组特定的坐标上。 Here is what I have so far.这是我到目前为止所拥有的。
public class Level1 extends JFrame implements ActionListener {
static JLayeredPane EverythingButPlayer;
static Level1 l1;
public Level1() {
EverythingButPlayer = new JLayeredPane();
BufferedImage img = null;
try {
img = ImageIO.read(new File("BeachRoad.png"));
} catch (IOException e) {
}
Graphics g = img.getGraphics();
g.drawImage(img,0, 0, EverythingButPlayer);
this.add(EverythingButPlayer);
}
And in the Main(),在 Main() 中,
l1 = new Level1();
l1.setTitle("poop");
l1.setSize(1920, 1080);
l1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
l1.setVisible(true);
Thanks in advance!提前致谢!
Try this:尝试这个:
package com.sandbox;
import javax.imageio.ImageIO;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.WindowConstants;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
public class SwingSandbox {
public static void main(String[] args) throws IOException {
JFrame frame = buildFrame();
final BufferedImage image = ImageIO.read(new File("C:\\Projects\\MavenSandbox\\src\\main\\resources\\img.jpg"));
JPanel pane = new JPanel() {
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
g.drawImage(image, 0, 0, null);
}
};
frame.add(pane);
}
private static JFrame buildFrame() {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.setSize(200, 200);
frame.setVisible(true);
return frame;
}
}
There are a lot of methods, but I always override the paint(Graphics g)
of a JComponent
and use g.drawImage(...)
有很多方法,但我总是覆盖
JComponent
的paint(Graphics g)
并使用g.drawImage(...)
edit: I was making a sample, but Daniel Kaplan did it perfectly, look at his answer :)编辑:我正在制作一个样本,但丹尼尔卡普兰做得很好,看看他的回答:)
