提问by Daniel Patilea
How can I fill the following rectangle using an image? Can anyone help me please?
如何使用图像填充以下矩形？有人可以帮我吗？
public void paintComponent(Graphics g) {
setOpaque(false);
//Paint a filled rectangle at user's chosen point.
if (point != null) {
g.drawRect(0, 0,
rectWidth - 1, rectHeight - 1);
g.setColor(Color.yellow);
g.fillRect(1, 1,
rectWidth - 2, rectHeight - 2);
}}
I tried this code but I couldn't find a way to make it work:
我试过这段代码，但找不到让它工作的方法：
File imageFile = new File("duck.jpg");
BufferedImage img;
Graphics2D graph = img.createGraphics();
graph.setColor(Color.BLACK);
graph.fill(new Rectangle(1, 2, rectWidth, rectHeight));
graph.dispose();
ImageIO.write(img, "jpg", new File("duck.jpg"));

You have to load an image into an Image object (like BufferedImage) and then call
您必须将图像加载到 Image 对象（如 BufferedImage）中，然后调用
graphics.drawImage()
graphics.drawImage()
on that image, giving the coordinates and other info.
在那个图像上，给出坐标和其他信息。
