Issue using ImageIO.write jpg file: pink background

I'm using the following code to write a jpg file:

String url="http://img01.taobaocdn.com/imgextra/i1/449400070/T2hbVwXj0XXXXXXXXX_!!449400070.jpg";
String to="D:/temp/result.jpg";
ImageIO.write(ImageIO.read(new URL(url)),"jpg", new File(to));

But I get the result.jpg is a pink background image:

You can work around this by using Toolkit.createImage(url) instead of ImageIO.read(url) which uses a different implementation of the decoding algorithm.

If you are using the JPEG encoder included with the Sun JDK then you must also ensure that you pass it an image with no alpha channel.

Example:

private static final int[] RGB_MASKS = {0xFF0000, 0xFF00, 0xFF};
private static final ColorModel RGB_OPAQUE =
	new DirectColorModel(32, RGB_MASKS[0], RGB_MASKS[1], RGB_MASKS[2]);

    // ...

String sUrl="http://img01.taobaocdn.com/imgextra/i1/449400070/T2hbVwXj0XXXXXXXXX_!!449400070.jpg";
URL url = new URL(sUrl);
Image img = Toolkit.getDefaultToolkit().createImage(url);

PixelGrabber pg = new PixelGrabber(img, 0, 0, -1, -1, true);
pg.grabPixels();
int width = pg.getWidth(), height = pg.getHeight();

DataBuffer buffer = new DataBufferInt((int[]) pg.getPixels(), pg.getWidth() * pg.getHeight());
WritableRaster raster = Raster.createPackedRaster(buffer, width, height, width, RGB_MASKS, null);
BufferedImage bi = new BufferedImage(RGB_OPAQUE, raster, false, null);

String to = "D:/temp/result.jpg";
ImageIO.write(bi, "jpg", new File(to));

Note: My guess is that the color profile is corrupted, and Toolkit.createImage() ignores all color profiles. If so then this will reduce the quality of JPEGs that have a correct color profile.

I had similar problems. But then I solved it by using this one

   BufferedImage image = new BufferedImage(width, height,
			BufferedImage.TYPE_INT_RGB); 

   //do something to populate the image
   //such as
   image.setRGB( x, y, pixelValue); //set your own pixels color



   ImageIO.write(image, "jpg", new File("D:\\test.jpg"));

Note that I'm using Java version 1.6.0_25-b06 and It's just works fine.

Maybe you can check the Java version.

This works for me:

int w = originalImage.getWidth();
int h = originalImage.getHeight();
BufferedImage newImage = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB);
int[] rgb = originalImage.getRGB(0, 0, w, h, null, 0, w);
newImage.setRGB(0, 0, w, h, rgb, 0, w);

• for me the problem was not the reading but the writing
• ImageIO will happily write JPG files from ARGB BufferedImages
• Browsers/other programs then interpret this 4-channel file as CMYK color or something, resulting in the effect described in this question
• solution for me: make sure that that BufferedImage that is passed to ImageIO.write is of type RGB (not ARGB)
• this also explains why the problem only appears when saving to jpeg, but not when saving to png
• this took a long time for me to figure out because my own image tools always convert to ARGB on the fly, so I was always passing an ARGB image to ImageIO.write, without realizing it

BufferedImage originalImage = ImageIO.read(getContent());
BufferedImage newImage = new BufferedImage(originalImage.getWidth(), originalImage.getHeight(), BufferedImage.TYPE_3BYTE_BGR);
    
    for (int x = 0; x < originalImage.getWidth(); x++) {
    	for (int y = 0; y < originalImage.getHeight(); y++) {
    		newImage.setRGB(x, y, originalImage.getRGB(x, y));
    	}
    }

this did the trick for me

I faced the same issue when reading and writing images using ImageIO. After reading answers here I changed my JRE - from openjdk version "1.8.0_91" to HotSpot java version "1.8.0_102". The hint was not obvious in finnw's answer but it worth a try ;-)

And thus the issue resolved! So if you are using OpenJDK JRE and free to change your JRE, changing it HotSpot and you won't need to change your code.
