![]() PDPage specPage = (PDPage)pdDoc.getDocumentCatalog().getAllPages().get( 0 ) PDDocument pdDoc = PDDocument.load(pdfPath) public static String getPageContent(String pdfPath, int pageNumber) throws IOException In the code below I try to get the whole page dimension. See code below, and sorry if I got the point measurement wrong. ![]() This can be done by using a rectangular area. It's still a bit tricky but you might be able to figure this out if you already knew the begining text of the column (in a way to estimate the width and height). If you are looking into extracting part of a page, let's say 1 column only, then you need to get the dimensions of the column. Output.append(PdfTextExtractor.getTextFromPage(reader, pageNumber, new SimpleTextExtractionStrategy())) StringWriter output = new StringWriter() PdfReader reader = new PdfReader(pdfPath) Public static String getPageContent(String pdfPath, int pageNumber) throws IOException * Get plain text from a specific page in a pdf file. I didn't have any problem reading columns, no merged text, each column is being printed aside from the other. But I'm using the following code to read certain pages from PDF files. Right now, the iText content parser doesn't have callbacks for these operations, but it would be possible to add them without major difficulty. Once you have column X and Y, you can resort to a region filtered approachĪnother approach that may be equally feasible would be to analyze draw operations and look for long horizontal and vertical lines (assuming the columns are demarcated in a table-like format).This will give you potential location for column start/stop Y positions on the page. While scanning, also look for words that intersect the X position (but do not start on the X position).Scan for all other words that start at the same X position. For each word, draw an imaginary line running the full height of the page.Use an algorithm similar to that used in the default text extraction strategy (LocationAware.) to obtain a list of words and X/Y locations (be sure to account for rotation angle as well).If you need to obtain columns from arbitrary data, you've got some algorithm work ahead of you (if you get something working, I'd love to take a look). ![]() If you know in advanced where the columns are, then you can use a region filter on the text render listener callback (there is code in the iText library for doing this, and the latest version of the iText In Action book gives a detailed example). How you are going to determine where columns start and stop is entirely up to you - this is a difficult problem - PDF doesn't have any concept of columns (heck, it doesn't even have a concept of words - just putting together the text extraction that the default strategy provides is quite tricky). What you need to do is develop your own text extraction strategy (if you look at how PdfTextExtractor.getTextFromPage is implemented, you will see that you can provide a pluggable strategy). I am the author of the iText text extraction sub-system. Public static void main(String args) throws DocumentException, IOException Private static String OUTPUTFILE = "c:/new3.pdf" The problem is: some pdf files contain 2 columns and when I extract text I get a text file where columns are merged as the result (i.e. If (text.I need to extract text from pdf files using iText. Check if the text is between square brackets Loop through each page and extract text between square brackets This is the code it has given me // Open the PDF file I have tried using the ChatGPT bot but that hasnt been very successful. They are enclosed in square brackets, so I just need to extract all text between square brackets to a text or CSV file. What I need is help with what I think should be a simple script to read through a PDF and extract Document IDs. I am not that clued up on scripting, but have managed to adapt a few google searches to perform various tasks for in Adobe.
