Hi
I am using PDFBox 2.0.3
I need to return the byte array representation of a PDDocument without saving
it to disk, but I always get a zero length byte array.
My method loads a file and creates a PDDocument from it. It the modifies this
document by adding in extra pages and finally I want to return the byte array
of the modified document.
If I add report.save(new Fille("Some Path")) then the modified document is
correctly saved (but I don't want to do this) - how do I get a valid byte array
returned?
Thanks for your help
Martin
Here is my code
URI origReport =
ClassLoader.getSystemResource("pdf/FullInvestmentReport.pdf").toURI();
byte[] origReportAsBytes = Files.readAllBytes(Paths.get(origReport));
PDDocument report = PDDocument.load(origReportAsBytes);
URI location1 = ClassLoader.getSystemResource("pdf/AddFile1.pdf").toURI();
byte[] data1 = Files.readAllBytes(Paths.get(location1));
PDDocument docToAdd = PDDocument.load(data1);
int currentPage = 3;
if (docToAdd != null) {
for (int i = 0; i < docToAdd.getNumberOfPages(); i++) {
originalReport.getPages().insertAfter(docToAdd.getPage(i),
report.getPage(newCurrentPage++));
}
}
byte[] aggregatedReport = new PDStream(report).toByteArray();
return aggregatedReport;
