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。
1 public static BufferedImage getImages(byte[] data) throwsIOException {2 ByteArrayInputStream input = newByteArrayInputStream(data);3 returnImageIO.read(input);4 }
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：
1、使用awtToolkit
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
1 Image imageTookit =Toolkit.getDefaultToolkit().createImage(bytes);2 BufferedImage cutImage = BufferedImageBuilder.toBufferedImage(imageTookit);
BufferedImageBuilder源码：
public staticBufferedImage toBufferedImage(Image image) {if (image instanceofBufferedImage) {return(BufferedImage) image;
}//This code ensures that all the pixels in the image are loaded
image = newImageIcon(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();returnbimage;
}
如果该方法在Windows平台下使用正常，而在Linux平台上总是报异常，这种解决方式可以参考：/shixing_11/article/details/6897871/
2、使用阿里巴巴的SImpleImage
主要依赖以下jar包：commons-io-2.4.jar、commons-lang.jar、commons-logging-1.1.1.jar、jai_codec-1.1.3.jar、jai_core-1.1.3.jar
SimpleImage github地址：/alibaba/simpleimage
