pdf-parsing

问题 We are using PDFBox to extract text from PDF's. Some PDF's text can't be extract correctly. The following image shows a part from the PDF as image: After text extraction we get the following text: 3, 8 5 EU R 1 Netto 38,50 EUR 4,00 (Spaces are added between ',' and '8') Here is our code: PDDocument pdf = PDDocument.load(reuseableInputStream); PDFTextStripper pdfStripper = new PDFTextStripper(); pdfStripper.setSortByPosition(true); String text = pdfStripper.getText(pdf); We tried to play with

问题 We are developing a Pdf parser to be used along with our system. The requirement is such that, we store all the information on any pdf documents and should be able to reproduce the document as such (with minimal changes from original document). We did some googling and found iTextSharp be the best mate for our purpose. We are developing our project using .net. You might have guessed as i mentioned in my title requiring comparisons for specific versions of iTextSharp (4.1.6 vs 5.x). We know

问题 Background I'm using pdfquery to parse multiple files like this one. Problem I'm trying to write a generalized filer function, building off of the custom selectors mentioned in pdfquery's docs, that can take a specific range as an argument. Because this is referenced I thought I could get around this by supplying a partial function using functools.partial (as seen below) Input import pdfquery import functools def load_file(PDF_FILE): pdf = pdfquery.PDFQuery(PDF_FILE) pdf.load() return pdf

问题 I'd like to parse a pdf for texts containing both, binary and clear text data. When I try to do it with PdfReaderContentParser the GetResultantText method returns the right texts for the binary content but whitespaces for the clear text content. Here is the code I use: byte[] binaryPdf = File.ReadAllBytes(this.fileName); reader = new PdfReader(binaryPdf); PdfReaderContentParser parser = new PdfReaderContentParser(reader); for (int i = 1; i <= reader.NumberOfPages; i++) {

问题 Using c#, I want to see if a specific check box is checkd on a PDF page. The PDF file is not a form one. PDF could be something like: Sample file is here: MDS30ResidentP2.pdf (in this sample file, I want to somehow figure it out that check-box "E" in the question A1000 is checked. Again: the PDF is not in "form" format!). PS: none of the following posts was solved my problem: PDF Parsing extract CheckBox Fields value iTextSharp: reading radio button, check box states from a non-form PDF 回答1:

问题 Using peepdf I am analyzing two simple pdf files. Both files contain a single line of text ("ZYXWVUTSRQQRSTUVWXYZ") and were created on Mac OS X. The first file was created with TextEdit. There are only three streams, and looking at the first one (automatically decoded with peepdf) shows the text clearly.

问题 I would like to do some analysis on some properties listed in an upcoming auction. Unfortunately, the city running the auction does not publish the information in a structured format but instead provides a 700+ page PDF of the properties going up for auction. I'm wondering if the community has any thoughts as to how I can approach parsing said PDF into a structured format for insertion into a db or to create a spreadsheet of the properties. Here's an image of what each page represents: And

问题 I have an Arabic PDF, and I want to parse it into text document using Java. I have tried many times, and the English words parse successfully but the Arabic words don't. Can anyone recommend a solution that will convert the Arabic words properly as well? 回答1: I think you can use iText for pdf manipulation using Java. It supports Arabic too. 回答2: There are several libraries that come to mind. Apache Tika, iText or pdfbox will all more or less solve your problem. Although, I must put in a word

问题 I am trying to convert pdf to csv file. pdf file has data in tabular format with first row as header. I have reached to the level where I can extract text from a cell, compare the baseline of text in table and detect newline but I need to compare table borders to detect start of table. I do not know how to detect and compare lines in PDF. Can anyone help me? Thanks!!! 回答1: As you've seen (hopefully), PDFs have no concept of tables, just text placed at specific locations and lines drawn around
