Hi,
I have problems merging some pdf files containing interative forms.
In the first step i created and fill the single pds files.
This are ok stored with the variables.
In the second step I will merge these files in a single one pdf file.
The problem is that the filled fields are present only on the last page
of the new document, in all the previous pages are blank.
Any help ?
Thanks in advance.
The merge method:
/**
* Merge pdf's documents
*
* @param pdfs The files to be merged
*/
public PDFEditor( String[] pdfs ) {
try {
int pageOffset = 0;
ArrayList master = new ArrayList( );
int f = 0;
// Create a temp file
File fileName = new File( pdfs[ 0 ] );
File file = File.createTempFile( Tools.removeFileExtension(
fileName.getName( ) ) + "_", ".pdf" );
resultPdfFileName = file.getAbsolutePath( );
String outFile = resultPdfFileName;
Document document = null;
PdfCopy writer = null;
while ( f < pdfs.length ) {
// Create a reader for a certain document
PdfReader reader = new PdfReader( pdfs[ f ] );
reader.consolidateNamedDestinations( );
// Retrieve the total number of pages
int n = reader.getNumberOfPages( );
pageOffset += n;
if ( f == 0 ) {
// Step 1: creation of a document-object
document = new Document(
reader.getPageSizeWithRotation( 1 ) );
// Step 2: create a writer that listens to the document
writer = new PdfCopy( document, new
FileOutputStream( outFile ) );
// Step 3: open the document
document.open( );
}
// Step 4: add content
PdfImportedPage page;
for ( int i = 0; i < n; ) {
++i;
page = writer.getImportedPage( reader, i );
writer.addPage( page );
}
PRAcroForm form = reader.getAcroForm( );
if ( form != null ) {
writer.copyAcroForm( reader );
}
f++;
}
if ( master.size( ) > 0 ) {
writer.setOutlines( master );
}
// Step 5: close the document
document.close( );
} catch ( Throwable th ) {
Tools.handleException( th );
}
}
