Question: Once you've loaded a document:

```
public static void main(String[] args) throws IOException {
    PDDocument doc = PDDocument.load(new File("blah.pdf"));

```

How do you get the page by page printing color intent from the PDDocument? I read the docs, didn't see coverage.

Answer: 
This gets the output intents (you'll get these with high quality PDF files) and also the icc profiles for colorspaces and images:

```
    PDDocument doc = PDDocument.load(new File("XXXXX.pdf"));
    for (PDOutputIntent oi : doc.getDocumentCatalog().getOutputIntents())
    {
        COSStream destOutputIntent = oi.getDestOutputIntent();
        String info = oi.getOutputCondition();
        if (info == null || info.isEmpty())
        {
            info = oi.getInfo();
        }
        InputStream is = destOutputIntent.createInputStream();
        FileOutputStream fos = new FileOutputStream(info + ".icc");
        IOUtils.copy(is, fos);
        fos.close();
        is.close();
    }
    for (int p = 0; p < doc.getNumberOfPages(); ++p)
    {
        PDPage page = doc.getPage(p);
        for (COSName name : page.getResources().getColorSpaceNames())
        {
            PDColorSpace cs = page.getResources().getColorSpace(name);
            if (cs instanceof PDICCBased)
            {
                PDICCBased iccCS = (PDICCBased) cs;
                InputStream is = iccCS.getPDStream().createInputStream();
                FileOutputStream fos = new FileOutputStream(System.currentTimeMillis() + ".icc");
                IOUtils.copy(is, fos);
                fos.close();
                is.close();
            }
        }
        for (COSName name : page.getResources().getXObjectNames())
        {
            PDXObject x = page.getResources().getXObject(name);
            if (x instanceof PDImageXObject)
            {
                PDImageXObject img = (PDImageXObject) x;
                if (img.getColorSpace() instanceof PDICCBased)
                {
                    InputStream is = ((PDICCBased) img.getColorSpace()).getPDStream().createInputStream();
                    FileOutputStream fos = new FileOutputStream(System.currentTimeMillis() + ".icc");
                    IOUtils.copy(is, fos);
                    fos.close();
                    is.close();
                }
            }
        }
    }
    doc.close();

```

What this doesn't do (but I could add some of it if needed):

* colorspaces of shadings, patterns, xobject forms, appearance stream resources
* recursion in colorspaces like DeviceN and Separation
* recursion in patterns, xobject forms, soft masks
Using `itext pdf` library (fork of an older version 4.2.1) you could do smth. like:

```
PdfReader reader = new com.lowagie.text.pdf.PdfReader(Path pathToPdf);
PRStream stream = (PRStream) reader.getCatalog().getAsDict(PdfName.DESTOUTPUTPROFILE);
if (stream != null)
 {
  byte[] destProfile = PdfReader.getStreamBytes(stream);
 }

```

For extracting the profile from each page you could iterate over each page like

```
for(int i = 1; i <= pdfReader.getNumberOfPages(); i++)
 {
  PRStream prStream = (PRStream) pdfReader.getPageN(i).getDirectObject(PdfName.DESTOUTPUTPROFILE);
 if (stream != null)
  {
   byte[] destProfile = PdfReader.getStreamBytes(stream);
  }
 }

```
