Hi,
The Adobe Acrobat Standard (7.0 and over) support functionality "Open Table in
Spreadsheet", that let you select test in the PDF, click right button over the
selected text and open selected content in Excel.
We are using iText version 1.3.6 to merge multiple PDF documents in one. Before
merge "Open Table in Spreadsheet" functionality exist, after merge this
functionality does not exist.
Could you give me some suggestions what could be done to fix it? Does the
latest version 1.3.6 support this functionality?
Here is a code we use:
public void mergePdf(OutputStream out, DocumentRequestValue request)
throws PdfGenerationException {
List documents = request.getDocuments();
DocumentValue docVal = null;
PdfReader reader = null;
Document document = null;
PdfWriter writer = null;
try {
// if empty document set don't do anything
if (documents.size() < 1)
throw new PdfGenerationException(
"empty document set for request: "
+ request.getRequestId());
// log document access
DocumentRequestDAO requestDAO = new DocumentRequestDAO
();
request.setAccessSite("AI");
try {
requestDAO.logRequest(request);
} catch (DAOException daoe) {
logger.error(daoe);
throw new PdfGenerationException(daoe);
}
docVal = (DocumentValue) documents.get(0);
// create a pdf reader that reads actual file
reader = new PdfReader(getPdf(docVal));
// create a pdf document that will be used to retrieve
pdf details
document = new Document(reader.getPageSizeWithRotation
(1));
// create a pdf writer to write file
writer = PdfWriter.getInstance(document, out);
// add some meta info
document.addAuthor("Prudential Finantial");
document.addCreator("Prudential Finantial");
document.addSubject(
"iText Library - Copyright (C) 1999-2004 by
Bruno Lowagie and Paulo Soares. All Rights Reserved. ");
document.addTitle("Download Pdf");
// open the document once
document.open();
// don't know what this does
// somekind of page writer
PdfContentByte cb = writer.getDirectContent();
int docIndex = 0;
// loop on documents
while (true) {
// this is copied from itext examples, it is
weird
// don't know if it is all needed
// get number of pages in current doc
int pages = reader.getNumberOfPages();
// loop on each page in document
int i = 0;
PdfImportedPage page;
while (i < pages) {
i++;
document.setPageSize
(reader.getPageSizeWithRotation(i));
document.newPage();
// get page from reader
page = writer.getImportedPage(reader,
i);
int rotation = reader.getPageRotation
(i);
// think this for pages that aren't
landscape
// adds actual page to output
if (rotation == 90 || rotation == 270) {
cb.addTemplate(
page,
0,
-1f,
1f,
0,
0,
reader.getPageSizeWithRotation(i).height());
} else {
cb.addTemplate(page, 1f, 0, 0,
1f, 0, 0);
}
}
// update index, if just processed last doc
then stop
++docIndex;
if (docIndex == documents.size())
break;
// get next document for next pass through loop
//
// creating a new reader automatically updates
document
docVal = (DocumentValue) documents.get
(docIndex);
reader = new PdfReader(getPdf(docVal));
}
// closing document automatically closes reader/writer
//document.close();
} catch (IOException ex) {
logger.error("IOException from iText", ex);
throw new PdfGenerationException(ex, "IOException from
iText");
} catch (DocumentException ex) {
logger.error("DocumentException from iText", ex);
throw new PdfGenerationException(
ex,
"DocumentException from iText");
} finally {
// closing document automatically closes reader/writer
if (document != null) {
document.close();
}
}
}
Thanks
Ivaylo
