I have to merge two pdf Files using PdfBox of Apache. I have taken physical pdf files to do so. Below is the code:
PDFMergerUtility ut = new PDFMergerUtility();
ut.addSource(path1);
ut.addSource(path2);
ut.setDestinationFileName(path3);
ut.mergeDocuments(MemoryUsageSetting.setupMainMemoryOnly());
Files are merged perfectly but then have some constraints as below:
Please anyone help me achieve this requirement.
Call PDFMergerUtility.appendDocument(PDDocument destination, PDDocument source)
instead of merge. To load from a byte array, call PDDocument.load(array)
.
Btw: I'd discourage to merge PDDocument objects that you created yourself, this fails if you have font subsets (see issue PDFBOX-3243). Better save them (e.g. in a ByteArrayOutputStream
) and reload and then merge. To get a byte array from a ByteArrayOutputStream, use ByteArrayOutputStream.tobytearray()
.
