Free PDF/A validation using PdfBox preflight

Apachie PdfBox preflight can be used to validate PDF/A's.

using the exmple in the last entry:

issue the command:

java -classpath /home/fausser/LatestTrunk/PDFBox-trunk/trunk/preflight/target/preflight-1.8.0-SNAPSHOT-jar-with-dependencies.jar org.apache.pdfbox.preflight.Validator_A1b /home/fausser/Fixflag/AnnontsPDFA.pdf

The file /home/fausser/Fixflag/AnnontsPDFA.pdf is a valid PDF/A-1b file

download the jar file from:
https://builds.apache.org/job/PDFBox-trunk/lastBuild/org.apache.pdfbox$preflight/

freely convert PDFs to PDF/A using ghostscript-9.07

 Here is an updated better way to freely convert PDFs to PDF/A using ghostscript-9.07


Convert annots.pdf to AnnotsPDFA.pdf

> /home/fausser/ghostscript-9.07/bin/gs -sDEVICE=pdfwrite -q -dNOPAUSE -dBATCH -dNOSAFER -dPDFA -dUseCIEColor -sProcessColorModel=DeviceCMYK -sOutputFile=AnnontsPDFA.pdf annots.pdf
GPL Ghostscript 9.07: Annotation set to non-printing,
 not permitted in PDF/A, reverting to normal PDF output

 Need to set the flag with a java program.....here is the code listing:
>cat  FixPrintFlag.java

//package Utilities;

import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;
import org.apache.pdfbox.pdmodel.interactive.annotation.PDAnnotation;
import org.apache.pdfbox.pdmodel.interactive.annotation.PDAnnotationLink;


import java.util.List;

 public class FixPrintFlag
{
        public StringBuffer errMsg = new StringBuffer();


    private FixPrintFlag()
    {
        //utility class, should not be instantiated.
    }


                              public static void main( String[] args ) throws Exception
    {
        PDDocument doc = null;
        try
        {
            if( args.length != 2 )
            {
                usage();
            }
            else
            {
                doc = PDDocument.load( args[0] );
                List allPages = doc.getDocumentCatalog().getAllPages();
                                for ( int i=0; i< allPages.size(); i++ ) {
                                        PDPage page = (PDPage)allPages.get( i );
                                        List annotations = page.getAnnotations();
                                        for ( int j = 0; j < annotations.size(); j++ ) {
                                                PDAnnotation annot = (PDAnnotation)annotations.get( j );
                                                        if ( annot instanceof PDAnnotationLink ) {
                                                                        PDAnnotationLink link = (PDAnnotationLink)annot;
                                                                        link.setPrinted(true);
                                                                        System.out.println("setting print flag...");
                                                                        }
                                        }
                                }
                        }
                        if (args[1] != null)
                                doc.save(args[1]);
        } catch (Exception ex) {
                                System.err.println("Error parsing pdf: " + ex.getMessage());
        }
}
  private static void usage()
    {
        System.err.println( "Usage: java org.pdfbox.examples.pdmodel.FixPrintFlag " );
    }

}

To compile it......using  Apache's pdfbox.jar and commons-logging.jar
javac -cp /home/fausser/Fixflag/pdfbox.jar:/home/fausser/Fixflag/commons-logging.jar FixPrintFlag.java


 
 And Run it......

> java -cp /home/fausser/Fixflag/pdfbox.jar:/home/fausser/Fixflag/commons-logging.jar:. FixPrintFlag annots.pdf annots_out.pdf

not a PDFA  yet, does not verify as one using Adobe Acrobat Pro 11x.....needs OputIntent by using PDFA_def.ps:

cat /home/fausser/ghostscript-9.07/lib/PDFA_def.ps

%!
% This is a sample prefix file for creating a PDF/A document.
% Feel free to modify entries marked with "Customize".

% This assumes an ICC profile to reside in the file (ISO Coated sb.icc),
% unless the user modifies the corresponding line below.

% Define entries in the document Info dictionary :

gs command using PDFA_def.ps
> /home/fausser/ghostscript-9.07/bin/gs -sDEVICE=pdfwrite -q -dNOPAUSE -dBATCH -dNOSAFER -dPDFA -dUseCIEColor -sProcessColorModel=DeviceCMYK -sOutputFile=/home/fausser/Fixflag/AnnontsPDFA.pdf /home/fausser/ghostscript-9.07/lib/PDFA_def.ps  /home/fausser/Fixflag/annots_out.pdf
[fausser@sally Fixflag]$

now it verifies as one
