pdfbox

Using Apache PDFBox, I am editing an existing document and I would like to take one page from that document and simply clone it, copying whatever elements it contains. As an additional twist, I would like to get a reference to all the PDField s for any form fields in this newly cloned page. Here's the code I tried so far: PDPage newPage = new PDPage(lastPage.getCOSDictionary()); PDFCloneUtility cloner = new PDFCloneUtility(pdfDoc); pdfDoc.addPage(newPage); cloner.cloneMerge(lastPage, newPage); // there doesn't seem to be an API to read the fields from the page, need to filter them out from the

Recently I downloaded pypdfocr , however, in the documentation there are no examples of how to call pypdfocr as a library, could anybody help me to call it just to convert a single file?. I just found a terminal command: $ pypdfocr filename.pdf If you're looking for the source code, it's normally under the directory site-package of your python installation. What's more, if you're using a IDE (i.e. Pycharm), it would help you find the directory and file. This is extremly useful to find class as well and show you how you can instantiate it, for example : https://github.com/virantha/pypdfocr/blob

I created code that adds an image to an existing pdf document and then signs it, all using PDFBox (see code below). The code nicely adds the image and the signature. However, in some documents, Acrobat Reader complains that "The signature byte range is invalid." The problem seems to be the same as the problem described in this question. The answer to that question describes the problem in more detail: the problem is that my code leaves a mix of cross reference types in the document (streams and tables). Indeed, some documents won't even open because of the problems that this creates. My

I'm writing a simple scanning application using jfreesane and Apache PDFBox . Here is the scanning code: InetAddress address = InetAddress.getByName("192.168.0.17"); SaneSession session = SaneSession.withRemoteSane(address); List<SaneDevice> devices = session.listDevices(); SaneDevice device = devices.get(0); device.open(); device.getOption("resolution").setIntegerValue(300); BufferedImage bimg = device.acquireImage(); File file = new File("test_scan.png"); ImageIO.write(bimg, "png", file); device.close(); And making PDF: PDDocument document = new PDDocument(); float width = bimg.getWidth();

How to determine whether a PDF page contains text or is purely picture, using Java? I searched through many forums and websites, but I can not find an answer yet . Is it possible to extract text from PDF, to know if the page is in the format picture or text? PdfReader reader = new PdfReader(INPUTFILE); PrintWriter out = new PrintWriter(new FileOutputStream(OUTPUTFILE)); for (int i = 1; i <= reader.getNumberOfPages(); i++) { // here I want to test the structure of the page !!!! if it's possible out.println(PdfTextExtractor.getTextFromPage(reader, i)); } There is no water-proof way to do what

I would like to draw a vector image on a PDF with Apache PDFBox. This is the code I use to draw regular images PDPage page = (PDPage) document.getDocumentCatalog().getAllPages().get(1); PDPageContentStream contentStream = new PDPageContentStream(document, page, true, true); BufferedImage _prevImage = ImageIO.read(new FileInputStream("path/to/image.png")); PDPixelMap prevImage = new PDPixelMap(document, _prevImage); contentStream.drawXObject(prevImage, prevX, prevY, imageWidth, imageHeight); If I use a svg or wmf image instead of png, the resulting PDF document comes corrupted. The main reason

This question already has an answer here: Reading a particular page from a PDF document using PDFBox 6 answers I know how to read text of an entire pdf file usinf PDFBox using PDFTextStripper.getText(PDDocument) . I also have a sample on how to get an object reference to a particular page using PDDocumentCatalog.getAllPages().get(i) . How do I get the text of just one page using PDFBox as I dont see any such method on PDPage class? You can set parameters on the PDFTextStripper to read particular pages: PDDocument doc; // document int i; // page no. PDFTextStripper reader = new PDFTextStripper(
