Issue using ImageIO.write jpg file: pink background [closed]

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.
