I am merging tagged pdf with untagged pdf. I am getting exception when I close
Document object:
NullPointerException(PdfCopy.java:890)
Call stack
com.itextpdf.text.pdf.PdfCopy.fixTaggedStructure(PdfCopy.java:890)
com.itextpdf.text.pdf.PdfCopy.flushTaggedObjects(PdfCopy.java:866)
com.itextpdf.text.pdf.PdfDocument.close(PdfDocument.java:855)
com.itextpdf.text.Document.close(Document.java:416)
......
Code:
PdfReader basePDF = new PdfReader( byteArray );
PdfReader legendInformation = new PdfReader( legendsStaticPDFs.get(
language ) );
boolean isBasePDFTagged = basePDF.isTagged();
boolean islegendInformationTagged = legendInformation.isTagged();
// Representation of the resultant, merged, PDF
Document document = new Document( basePDF.getPageSize( 1 ) );
// Wrap the target PDF in something concrete to facilitate adding pages
ByteArrayOutputStream outputStreamNew = new ByteArrayOutputStream();
PdfCopy newPDF = new PdfCopy( document, outputStreamNew );
newPDF.setTagged();
// Set the PDF language (Accessibility standards)
newPDF.getExtraCatalog().put(PdfName.LANG,
new PdfString( language.locale.getLanguage() ) );
// Set the PDF document title (Accessibility standards)
newPDF.getInfo().put(PdfName.TITLE, new PdfString(
messageSourceAccessor.getMessage(
"statement.pdf.title." + language.locale.getLanguage()
) ) );
document.open();
appendPDF( newPDF, basePDF );
//appendPDF( newPDF, legendInformation );
document.close();
I checked this Merging Tagged PDF without ruining the
tags<http://stackoverflow.com/questions/19839445/merging-tagged-pdf-without-ruining-the-tags>,
and have found that it should be fixed, but it still exist at least in iText
5.5.2 I used. Is it any work around? Could PageName.PG be set manually? Thanks
in advance.
