How to create and add a ICCBased color profile into pdf document

[Thach Tran]

Hi!
I'm doing some document conversion and right now I'm trying to find a 
way to create a ICCBased color space in pdf using pdfbox. I have a file 
call cs-0.icc which is a color profile. This is a sequence of bytes in a 
standard format which I believe pdf also use the same thing. Below is my 
attempt.


           RandomAccessBuffer buffer1 = new RandomAccessBuffer();
           FileInputStream fs = null;
           try {
               fs = new FileInputStream("cs-0.icc");
               int c;
              
               while ((c = fs.read()) != -1) {
                   buffer1.write(c);
               }
           }
           finally {
               if (fs != null)
                   fs.close();
           }
           COSArray iccArray = new COSArray();
           COSStream streamObj = new COSStream(buffer1);
           iccArray.add(COSName.getPDFName("ICCBased"));
           iccArray.add(streamObj);
           PDICCBased col1 = new PDICCBased(iccArray);


Here is the stack trace I got back.

Any idea how may I get around this.
Thank you very much.
