问题 I'm using Apache PDFBox to extract pages from PDF files and I can't find a way to extract content that is unselectable (either text or images). With content that is selectable from within the PDF files there is no problem.

On the same PDF file there is

问题 I am doing project in Java using PDFBOX-1.8.6 library (its compulsory to use). My Question is How can I check input pdf file have portrait or landscape orientation ? How to check/scan portrait or landscape orientation in PDF by its dimensions of each page if both are same? For example, both are in standard A4 size. You will be more clear by below picture. my Landscape - Portrait problem I just want to check its content is rotated or not. So How can I cope up with above problem ? 回答1: Assuming

问题 I'm trying to scaling an image with size = 2496 x 3512 into a PDF document. I'm using PDFBox to generate it but the scaled image ends up blurred. Here are some snippets: PDF Page size (A4) returned by page.findMediaBox().createDimension(): java.awt.Dimension[width=612,height=792] Then I calculate the scaled dimension based on the Page size vs. Image size which returns: java.awt.Dimension[width=562,height=792] I use the code below in order to calculate the scaled dimension: public static

问题 When I try to draw png images using pdfBox, the pages remain blank. Is there any way to insert png images using pdfBox? public void createPDFFromImage( String inputFile, String image, String outputFile ) throws IOException, COSVisitorException { // the document PDDocument doc = null; try { doc = PDDocument.load( inputFile ); //we will add the image to the first page.

问题 I am writing a Master's thesis - NLP system. I have one component - extractor. It is extracting a plain text from PDF files. There are a few PDF files that can not be extracted correctly. Extractor (PDFBox library) returns a string like this: "┤xDn║if|d├gDF"Ti&cD╬lh d FÁhis~n ╗xd f«"d┤ffih »h" or "10a61a91a22a25a3a27a17a23a20a8a13a14a61a25a17" I was checking each file that makes this extraction's problem and all these files' text also can not be copy-pasted from PDF Reader (Adobe Reader and

问题 I'm trying to use PDFBox 2.0 for text extraction. I would like to get information on the font size of specific characters and the position rectangle of that character on the page. I've implemented this in PDFBox 1.6 using a PDFTextStripper: PDFParser parser = new PDFParser(is); try{ parser.parse(); }catch(IOException e){ } COSDocument cosDoc = parser.getDocument(); PDDocument pdd = new PDDocument(cosDoc); final StringBuffer extractedText = new StringBuffer(); PDFTextStripper textStripper =
