问题 I am trying to copy annotations from one pdf to another. But copying even 1 annotation DOUBLES the size of outputing pdf file. Please find below simple code sample: PDDocument pdf = PDDocument.load(new File("test1.pdf")); PDDocument pdf2 = PDDocument.load(new File("test/test1.pdf")); List<PDAnnotation> pdfAnnotations1 = pdf.getPage(0).getAnnotations(); List<PDAnnotation> pdfAnnotations2 = pdf2.getPage(0).getAnnotations(); pdfAnnotations1.add(pdfAnnotations2.get(0)); pdf.save("test1.pdf"); If

问题 I have seen how to do this in previous versions like below: How to extract font styles of text contents using pdfbox? But I think the getFonts() method has been removed now. I want to retrieve a map of texts to fonts ( Map<String, PDFont> ) in the new version of PDFBox but I have no idea how. Thanks Kabeer 回答1: Do this: PDDocument doc = PDDocument.load("C:/mydoc3.pdf"); for (int i = 0; i < doc.getNumberOfPages(); ++i) { PDPage page = doc.getPage(i); PDResources res = page.getResources(); for

问题 I am new to PDFBox and am stuck at finding the height of an image in inches. After a couple of searches, this is the piece of code that I am working with: PDResources resources = aPdPage.findResources(); graphicsState = new PDGraphicsState(aPdPage.findCropBox()); pageWidth = aPdPage.findCropBox().getWidth() / 72; pageHeight = aPdPage.findCropBox().getHeight() / 72; @SuppressWarnings("deprecation") Map<String, PDXObjectImage> imageObjects = resources.getImages(); if (null == imageObjects ||

问题 In my previous SO question PDFBox 1.8.10: Fill and Sign PDF produces invalid signatures I explained, how I failed to fill and afterwards sign a PDF-Document, using PDFBox 1.8.10. After this got sorted out with some kind help, I now continue to work on the same topic. Starting with doc_v2.pdf (links to the file are below!), I fill and sign it, resulting in doc_v2_fillsigned.pdf (doing it in one go, saving it incrementally). Again I open the edited document (using again PDFBox) and try to fill

问题 I am using PDFBox and have the following code snippet, which is reading a PDF file and converting it to image (PNG). It is working well, the only problem is that it is completely losing the barcode value that is in the PDF file. Does anyone know how to work around this with PDFBox? Is that even possible? Thanks. PDDocument doc = PDDocument.load(new File("INPUT.pdf")); PDPage page = (PDPage) doc.getDocumentCatalog().getAllPages().get(0); BufferedImage image = page.convertToImage(); File

问题 I am trying to populate repeated forms with PDFbox. I am using a TreeMap and populating the forms with individual records. The format of the pdf form is such that there are six records listed on page one and a static page inserted on page two. (For a TreeMap larger than six records, the process repeats). The error Im getting is specific to the size of the TreeMap. Therein lies my problem. I can't figure out why when I populate the TreeMap with more than 35 entries I get this warning: Apr 23,

问题 File example: file. Problem - when extracting text using PdfTextStripper, there is token "9/1/2017" and "387986" after "ASSETS" in the page start which should be removed, and some others hidden tokens. I have already applied this solution (so I do not copy-paste it here, because actually problem is exactly the same) and still that hidden text is appearing on page. Could it be hidden by something else except clip path? thanks! 回答1: Could it be hidden by something else except clip path? Yes. In

问题 In my program I am downloading misc. PDF documents and at the very end I want to merge those into one combined document using Apache pdfbox (v1.8.8). For some strange reason the PDFMergerUtility fails claiming that the files are encryped - which they are obviously not! I can open them in Adobe Reader and other PDF viewers without any issue and without having to provide any password. The Java exception and stack trace reads: Feb 28, 2015 6:25:54 PM org.apache.pdfbox.pdfparser.PDFParser parse

问题 I'm using PDFBox to show a generated pdf-file in my application. I added the PdfPagePanel to a JScrollPane.

Enviroment: PDFBox 1.7.1, Windows 7, Java 1.6.31 Thanks in advance, Sascha 回答1: I still
