An easy way to support CMYK and YCCK is to convert the raster to
RGB.
The code below does this and has been tested on Adobe YCCK,
Adobe CMYK, and non-Adobe CMYK (there is no non-Adobe YCCK).
Sun is welcome to use this code in any way.
If the conversion were done by IIO, it would be
more convenient obviously,
be faster and use less memory since samples would be directly
accessible,
and be easier to obtain transform field of Adobe APP14 marker
as opposed to inspecting metadata or reparsing the JPEG data
format.
/**
Java's ImageIO can't process 4-component images
and Java2D can't apply AffineTransformOp either,
so convert raster data to RGB.
Technique due to MArk Stephens.
Free for any use.

Recode a sRGB jpeg to a CMYK jpeg with a CMYK color profile:
JPEGImageDecoder decoder = JPEGCodec
.createJPEGDecoder(new ByteArrayInputStream(tmp));
BufferedImage rgbImage = decoder.decodeAsBufferedImage();
// Create a CMYK Color Space from a CMYK- Profile,
// there exists lots of, look at: http://www.eci.org/eci/de/060_downloads.php
// if you don't know take: ISOcoated.icc ...
String cmykProfile = "c:\\temp\\ECI_Offset_2004\\ISOcoated.icc";
ICC_Profile p = ICC_Profile.getInstance(new FileInputStream(cmykProfile));
ColorSpace cmykCS = new ICC_ColorSpace(p);
ByteArrayOutputStream out = new ByteArrayOutputStream();
// OutputStream out = new FileOutputStream(cmykJPEGFile);
// ColorConvert rgbImage to CMYK
ColorSpace rgbCS = rgbImage.getColorModel().getColorSpace();
ColorConvertOp rgbToCmyk = new ColorConvertOp(rgbCS, cmykCS,
null);
// Create a ColorModel for destination CMYK image
int[] bits = null;
ColorModel cmykModel = new ComponentColorModel(cmykCS, bits,
false, false, Transparency.OPAQUE, DataBuffer.TYPE_BYTE);
WritableRaster cmykRaster = cmykModel
.createCompatibleWritableRaster(rgbImage.getWidth(),
rgbImage.getHeight());
// Convert to CMYK now
rgbToCmyk.filter(rgbImage.getRaster(), cmykRaster);
// encode to jpeg
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(
cmykRaster, JPEGDecodeParam.COLOR_ID_CMYK);
param.setQuality(0.75f, false);
encoder.encode(cmykRaster, param);
out.close();
eo.setContent(out.toByteArray());
Read a jpeg that is a CMYK with Color Profile an convert it to Buffered Image:
inputStream = ImageIO.createImageInputStream(instr);
reader = findReader(inputStream);
reader.setInput(inputStream);
try {
// Try reading an image (including color conversion).
jpegBufferedImage = reader.read(0);
} catch (IIOException e) {
// Try reading a Raster (no color conversion)....
Raster raster = reader.readRaster(0, null);
// ...and hope thats a CMYK, take a CMYK-Profile,
//there exists lots of, look at: http://www.eci.org/eci/de/060_downloads.php
// if you don't know take: ISOcoated.icc ...
String cmykProfile = "c:\\temp\\ECI_Offset_2004\\ISOcoated.icc";
ICC_Profile p = ICC_Profile
.getInstance(new FileInputStream(cmykProfile));
//... and convert it to sRGB
jpegBufferedImage = cmykRasterToSRGB(raster, p);
}
Using :
/**
* Java's ImageIO can't process 4-component images and Java2D can't apply
* AffineTransformOp either, so convert raster data to sRGB.
*/
public static BufferedImage cmykRasterToSRGB(Raster raster,
ICC_Profile cmykProfile) {
int w = raster.getWidth();
int h = raster.getHeight();
ColorSpace cmykCS = new ICC_ColorSpace(cmykProfile);
BufferedImage rgbImage = new BufferedImage(w, h,
BufferedImage.TYPE_INT_RGB);
WritableRaster rgbRaster = rgbImage.getRaster();
ColorSpace rgbCS = rgbImage.getColorModel().getColorSpace();
ColorConvertOp cmykToRgb = new ColorConvertOp(cmykCS, rgbCS, null);
cmykToRgb.filter(raster, rgbRaster);
return rgbImage;
}
