Second try:
I have many different Pdfs, lets say chapters from a book. I want to put
them together into one Pdf. Furthermore I want to create a table of
contents.
The final Pdf exists of a table of contents and all chapters of the book.
The table of contents should have links to the particular chapter.
Now the code (I haven´t considered the links yet):
In the first step I create the table of contents. I saved the names of the
chapters in one array (called "namesOfPages"). Creating the table of
contents works without problems.
In the second step I want to append each Pdf (each chapter of the book) to
the final Pdf. When I open the final Pdf (called "all.pdf") it contains only
the chapter, not the table of contents. When I uncomment the second step the
final Pdf contains the table of content. Because of this I think, that the
table of contents will be overwritten. You understand?
Now I want to know, what I can to, to get this two parts (table of contents
and chapters) into one Pdf. Thanks for help!
//--------------------------FIRST STEP----------------------------------
String outFile = OUTPUT_FILE;
Document document = new Document();
PdfWriter writer2 = null;
writer2.getInstance(document, new FileOutputStream("C:\\Dokumente und
Einstellungen\\jergi\\Desktop\\pdf\all.pdf"));
document.open();
Paragraph tx = new Paragraph("TABLE OF CONTENTS");
document.add(tx);
while(namesOfPages[w] != null)
{
pagenumber = pagenumber + numberOfPages[w];
Paragraph txx = new Paragraph(namesOfPages[w] + "\t" + pagenumber);
document.add(txx);
w++;
}
document.close();
//--------------------------SECOND STEP-----------------------------------
//path to the pdf which will be copied next. The Pdfs are called 1.pdf 2.pdf
3.pdf......
String generatedPDF = OOFFICE_OUTPUT_FOLDER + File.separator +
PdfNameCounter + ".pdf";
reader = new PdfReader( generatedPDF );
PdfCopy writer = null;
writer = new PdfCopy( document, new FileOutputStream( outFile, true ) );
while ( PdfNameCounter < numberPDFs )
{
//pdf which will be copied next
generatedPDF = OOFFICE_OUTPUT_FOLDER + File.separator + PdfNameCounter +
".pdf";
File pdf = new File( generatedPDF );
if( !pdf.exists() )
{
PdfNameCounter++; //if this pdf doesn´t exist, take the next one
continue;
}
reader = new PdfReader( generatedPDF );
document.open();
int n = reader.getNumberOfPages();
numberOfPages[PdfNameCounter - 1] = n;
PdfImportedPage page;
for ( int i = 1; i <= n; i++)
{
page = writer.getImportedPage( reader, i );
writer.addPage( page );
}
//pdf.delete();
PdfNameCounter++;
}
document.close();
