Thanks for your reply:
here is my requirement:
- Convert PDF Level 1.4 to PDF/A
- all fonts embedded
- stripping out forms
- able to convert Digital Signature
below is the code snipped which i wrote using jar IText 2.1.3 . This code
convert PDF to PDF/A , but I do not know that, it is covering my above
requirement or not.
private static void convert() throws Exception{
//Name of the pdf/A converted
String pdfA = "C:\\ACC\\PDFtoPDFA\\my.pdf";
//Name of the pdf to convert
String pdf = "C:\\ACC\\PDFtoPDFA\\DebitCardOverdraft.pdf";
//Reads a PDF document.
PdfReader reader = new PdfReader(pdf);
//PdfStamper: Applies extra content to the pages of a PDF document.
This extra content can be all the objects allowed in
//PdfContentByte including pages from other Pdfs.
PdfStamper stamper = new PdfStamper(reader, new
FileOutputStream(pdfA));
//A generic Document class.
Document document = new Document();
// we create a writer that listens to the document
PdfWriter writer = stamper.getWriter();
int numberPages = reader.getNumberOfPages();
writer.setPDFXConformance(PdfWriter.PDFA1A);
document.open();
//PdfDictionary:A dictionary is an associative table containing
pairs of objects.
//The first element of each pair is called the key and the
second
element is called the value
//<CODE>PdfName</CODE> is an object that can be used as a name
in a
PDF-file
PdfDictionary outi = new PdfDictionary(PdfName.OUTPUTINTENT);
outi.put(PdfName.OUTPUTCONDITIONIDENTIFIER, new PdfString("sRGB
IEC61966-2.1"));
outi.put(PdfName.INFO, new PdfString("sRGB IEC61966-2.1"));
outi.put(PdfName.S, PdfName.GTS_PDFA1);
writer.getExtraCatalog().put(PdfName.OUTPUTINTENTS, new
PdfArray(outi));
//Add pages
PdfImportedPage p = null;
Image image;
for(int i=0; i< numberPages; i++){
p = writer.getImportedPage(reader, i+1);
image = Image.getInstance(p);
document.add(image);
}
writer.createXmpMetadata();
document.close();
//Add Metadata from source pdf
HashMap info = reader.getInfo();
stamper.setMoreInfo(info);
stamper.close();
// showFileSize(pdfA);
}
