Java处理某些图片红色问题

问题现象：

Java上传图片时，对某些图片进行缩放、裁剪或者生成缩略图时会蒙上一层红色，经过检查只要经过ImageIO.read()方法读取后再保存，该图片便已经变成红图。因此，可以推测直接原因在于ImageIO.read()方法加载图片的过程存在问题。

public static BufferedImage getImages(byte[] data) throws IOException {
        ByteArrayInputStream input = new ByteArrayInputStream(data);
        return ImageIO.read(input);
    }

经过查阅得知ImageIO.read()方法读取图片时可能存在不正确处理图片ICC信息的问题，ICC为JPEG图片格式中的一种头部信息，导致渲染图片前景色时蒙上一层红色。

解决方案：

不再使用ImageIO.read()方法加载图片，而使用JDK中提供的Image src=Toolkit.getDefaultToolkit().getImage

Image src=Toolkit.getDefaultToolkit().getImage(file.getPath());
BufferedImage image=BufferedImageBuilder.toBufferedImage(src);//Image to BufferedImage

或者Toolkit.getDefaultToolkit().createImage

Image imageTookit = Toolkit.getDefaultToolkit().createImage(bytes);
BufferedImage cutImage = BufferedImageBuilder.toBufferedImage(imageTookit);

BufferedImageBuilder源码：

public static BufferedImage toBufferedImage(Image image) {
        if (image instanceof BufferedImage) {
            return (BufferedImage) image;
        }
        // This code ensures that all the pixels in the image are loaded
        image = new ImageIcon(image).getImage();
        BufferedImage bimage = null;
        GraphicsEnvironment ge = GraphicsEnvironment
                .getLocalGraphicsEnvironment();
        try {
            int transparency = Transparency.OPAQUE;
            GraphicsDevice gs = ge.getDefaultScreenDevice();
            GraphicsConfiguration gc = gs.getDefaultConfiguration();
            bimage = gc.createCompatibleImage(image.getWidth(null),
                    image.getHeight(null), transparency);
        } catch (HeadlessException e) {
            // The system does not have a screen
        }
        if (bimage == null) {
            // Create a buffered image using the default color model
            int type = BufferedImage.TYPE_INT_RGB;
            bimage = new BufferedImage(image.getWidth(null),
                    image.getHeight(null), type);
        }
        // Copy image to buffered image
        Graphics g = bimage.createGraphics();
        // Paint the image onto the buffered image
        g.drawImage(image, 0, 0, null);
        g.dispose();
        return bimage;
    }
