ImageIO.read() 无法读取某些图像

Question

我有一个 GIF 图像并尝试将其读入 BufferedImage。

public class ImageReadTest {

    public static void main(String[] args) throws IOException {
        f(new File("/Users/hieugioi/Downloads/Photos/butterfly.gif"));
    }

    public static void f(File file) throws IOException {
        BufferedImage image = ImageIO.read(file);
    }

}

显示错误：

"butterfly" 图片来自 this open source project:

其他常规图像成功，但这张图像失败。是图像问题还是API错误？

Answer 1

这是已知的 JDK 错误请参阅：

这些错误已在 Java 9.

中修复

Answer 2

我刚刚找到了此页面上出现的此问题的解决方案：http://web.archive.org/web/20200805050306/http://www.jguru.com/faq/view.jsp?EID=53328

解法： 通过使用 ImageIcon Class，您可以读取 gif 文件，然后将其绘制到新创建的 BufferedImage 中。

http://web.archive.org/web/20200805050306/http://www.jguru.com/faq/view.jsp?EID=53328解决方案的完整代码：

 import java.awt.*;
 import java.awt.image.*;
 import javax.swing.*;

 public class BuffIt {
 public static void main (String args[]) {
     // Get Image
     ImageIcon icon = new ImageIcon(args[0]);
     Image image = icon.getImage();

     // Create empty BufferedImage, sized to Image
     BufferedImage buffImage = 
       new BufferedImage(
           image.getWidth(null), 
           image.getHeight(null), 
           BufferedImage.TYPE_INT_ARGB);//you can use any type

     // Draw Image into BufferedImage
     Graphics g = buffImage.getGraphics();
     g.drawImage(image, 0, 0, null);

     // Show success
    JFrame frame = new JFrame();
    JLabel label = new JLabel(new ImageIcon(buffImage));
    frame.getContentPane().add(label);
    frame.pack();
    frame.show();
  }
}
