Extending COSName to produce PDF/A with correct OutputIntents
Hello,
First of all, thanks for this tool, found it very useful.
Below some sample code to include (sRGB) ICC profile and corresponding
OutputIntents to the generated PDF/A. The produced PDF successfully
passes validation.
It would be nice to have the COSName' extension included in the next
release so we won't have to use a homemade build.
Regards,
Elyes

* Extension in COSName (org.apache.pdfbox.cos)
public static final COSName OutputIntents = new COSName( "OutputIntents" );
public static final COSName OutputIntent = new COSName( "OutputIntent" );
public static final COSName DestOutputProfile = new COSName(
"DestOutputProfile" );
* Add new classes
public class OutputIntents implements COSObjectable {

dictionary = new COSDictionary();
dictionary.setItem(COSName.TYPE, COSName.OutputIntent);

/* Here you have to download .icc profile */
InputStream is =
OutputIntents.class.getResourceAsStream("/test/color/sRGB.icc");

* Sample code to include output intent

COSArray outputIntents = new COSArray();
outputIntents.add(oi);
root.setItem("OutputIntents", outputIntents);

Hi Elyes,
Thanks for your contribution.
I just have one side question. Did you validate your PDF/A with other
validators than preflight ?
KR,
Guillaume
