So I used another option: I use the existing LocationTextExtractionStrategy, and merely for the GetResultantText call I manipulate the underlying list of text chunks of the strategy. This would be kind of a long answer here, though. One option for this would be to add it to a copy of the LocationTextExtractionStrategy. This would have allowed you to parse the page once and extract text from text pieces in arbitrary page areas out of the box.īut it is possible to bring back that feature. How could I extract all the rectangles of a page in a single pass?Īs already mentioned in a comment, I was surprised to see that the iText 7 LocationTextExtractionStrategy does not anymore contain something akin to the iText 5 LocationTextExtractionStrategy method GetResultantText(TextChunkFilter). But, as you see, the extraction isn't batched. Each page has the same layout: a table with rows and columns.Ĭurrently, I'm using the method above to extract the text of each rectangle. My goal is to extract data from a PDF with multiple pages. It works, but I don't know if it's the best way to do it.Īlso, I wonder if the GetTextFromPage could be improved by the iText team to increase its performance, since I'm processing hundreds of pages in big PDFs and it usually takes more than 10 minutes to do it using my current configuration.įrom the comments: It seems that iText can extract the text of multiple rectangles on the same page in one pass, something that can improve the performance (batched operations tend to be more efficient), but how? Var str = PdfTextExtractor.GetTextFromPage(page, filteredTextEventListener) Var filteredTextEventListener = new FilteredTextEventListener(new LocationTextExtractionStrategy(), filter) Public static string ExtractText(this PdfPage page, Rectangle rect)įilter = new TextRegionEventFilter(rect) Simply right-click and paste the selection from your clipboard into any other application or document.Currently, I use this code to extract text from a Rectangle (area).
