java - 将 BufferedImage 转换为 ImageIcon

Question

如何将 BufferedImage 转换为 ImageIcon？

我找不到任何关于此的文档。

Answer 1

使用构造函数：ImageIcon(Image image)，BufferedImage扩展Image。

Answer 2

BufferedImageextends Image，所以很简单：

new ImageIcon(myBufferedImage);

Answer 3

File img = new File("C:\\..\\image.jpg");
BufferedImage bufferedImage = ImageIO.read(img);
ImageIcon imageIcon = new ImageIcon(bufferedImage);

Answer 4

your bufferimage;
JLabel photo = new JLabel("Photo");
photo.setIcon(new ImageIcon(bufferimage));

Answer 5

这是一个简单的转换器：

//Your icon
private ImageIcon icon;
//Your image
private BufferedImage image; 

 public void bufferImageTocon(){
     File file = new File("test.jpg");
     try {
         this.image = ImageIO.read(file);
     } catch (IOException ex) {
         ex.printStackTrace();
     } 

     icon = new ImageIcon(image); 
 }

仅使用构造函数来制作新图标，将缓冲图像设置为参数。
