CMYK 이미지 처리

File f = new File("/path/imagefile.jpg");

// Find a suitable ImageReader

Iterator readers = ImageIO.getImageReadersByFormatName("JPEG");

ImageReader reader = null;

while(readers.hasNext()){

reader = (ImageReader)readers.next();

if(reader.canReadRaster()){

break;

}

}

// Stream the image file (the original CMYK image)

ImageInputStream input = ImageIO.createImageInputStream(f); 

reader.setInput(input);

//Read the image raster

Raster raster = reader.readRaster(0, null);

//Create a new RGB image

BufferedImage bi = new BufferedImage(raster.getWidth(), raster.getHeight(), 

BufferedImage.TYPE_4BYTE_ABGR);

//Fill the new image with the old raster

bi.getRaster().setRect(raster);
