> I have a PDF with CMYK images inside and i need to extract the images in the RGB format. But the PDJpeg class seems to not work correctly; the colors are bad.  Example:
> - Original image in te PDF : http://ludoda.free.fr/IMAGE_IN_PDF.jpg
> - Extracted image: http://ludoda.free.fr/IMAGE_EXTRACTED.jpg
> You can download the PDF : http://ludoda.free.fr/PORSCHE_CMYK.PDF
> and try my simple Test Case (I'm using PDFbox 1.8.5): 
> {code}
> import java.awt.image.BufferedImage;
> import java.io.File;
> import java.io.IOException;
> import java.util.Iterator;
> import java.util.List;
> import java.util.Map;

> import org.apache.pdfbox.pdmodel.graphics.xobject.PDXObject;

> public class TestCase {
> 	
> 	public static void main(String[] args) 
> 	{
> 		try 
> 		{
> 			System.out.println("START EXTRACTING IMAGES...");
> 			read_pdf();
> 			System.out.println("COMPLETE");
> 		}
> 		catch (IOException ex) 
> 		{
> 		    System.out.println("" + ex);

> 		    Iterator<PDPage> iter = pages.iterator(); 
> 		    int i =1;

> 		        {

> 		            while (imageIter.hasNext())

> 		                	image.write2file("C:\\workspace\\JAVA_PDFTools\\temp\\image" + i);
>
