(This Java code should easily be translatable into C#. ( TextExtraction.java method extractSimple) Return "" void renderText(TextRenderInfo renderInfo) In Java this can be done by using an anonymous class like this: return PdfTextExtractor.getTextFromPage(reader, pageNo, new SimpleTextExtractionStrategy() It can easily be extended to also include markers corresponding to the start and end of text objects in its output. In the case at hand the SimpleTextExtractionStrategy is used. The most obvious structure like that in a generic PDF would be the text objects (in which multiple strings may be drawn). The OP indicated interest in a block structure inherent in the content stream. Then PDFBox extracts the text just like iText(Sharp) with the (default) LocationTextExtractionStrategy does PS: If one sets the PDFBox PDFTextStripper property SortByPosition to true like this PDFTextStripper stripper = new PDFTextStripper() As the order of those operations is arbitrary according to the PDF specification, any update of the software generating those PDFs may result in files from which the PDFBox PDFTextStripper and the iText SimpleTextExtractionStrategy extract merely an unintelligible soup of characters. So I think that PDF is really table structured.Īctually this order of extraction means merely that the operations for drawing the string segments in the PDF page content stream occur in this very order. With the exception of one space character per dataset (iText(Sharp) extracts Destination: Pick-up: instead of Destination:Pick-up:) the results are identical.Ĭoncerning your conclusion from PDFBox extracting the text as it does: one has to replace this line page = PdfTextExtractor.GetTextFromPage(reader, i) īy page = PdfTextExtractor.GetTextFromPage(reader, i, new SimpleTextExtractionStrategy()) Getting the same output with iText(Sharp) actually is very easy: One merely has to explicitly use the SimpleTextExtractionStrategy instead of the LocationTextExtractionStrategy which is used by default, i.e. This is not really a neat column-wise extraction but certain blocks of information (like address blocks) remain together. Returns for the section shown above Driver Book for Ĭompany IS MEDICAL AND Date of Service IS BETWEEN AND AND Status IS Assigned AND Vehicles IS MEDICAL: PDFTextStripper stripper = new PDFTextStripper() Using PDFBox (v1.8.10, the current release version) in this method: String extract(PDDocument document) throws IOException The OP's sample file contains multiple sections like this one:Īnother one tool parse my PDF exactly like I want. Maybe someone has appropriate code sample? I'd like to get such strings for upper example: Some Table Headerĭoes anyone have any idea how to tune itextsharp to get such behavior of pdf parser? I'd like to get concatenated strings that will reflect data from blocks. Will be concatenated into strings: Some Table Header With this code PdfReader reader = new PdfReader(pdfName) įor (int i = 1 i (page.Split(separators, StringSplitOptions.RemoveEmptyEntries)) Standard parser reads data from separate columns at the same line. My file is structurized and it contains tables and plain text. $doc.Add(::GetInstance( $image.I am having a problem with reading some data from pdf file. # Set the next page size to those dimensions and add a new page $rect = New-Object ($bmp.Width, $bmp.Height) # Create an iTextSharp rectangle that corresponds to those dimensions Net image so that we can get the image dimensions $writer = ::GetInstance($doc, $filestream) $fileStream = New-Object System.IO.FileStream($pdfFilePath, ::Create) # Create our stream, document and bind a writer $images = Get-ChildItem $imageFolderPath -Filter *.png $iTextSharpFilePath = "D:\DLLs\itextsharp.dll" The comments should hopefully get you the rest of the way. I've moved most of the variable to the top just to make things easier, you'll want to update them to match your needs. We instantiate a with each image to get the dimensions, create an iTextSharp Rectangle with those dimensions and then use that to set the page's size via $doc.SetPageSize(). One common request is to also have each page sized to fit the image so I've added that, too. You'll then want to use ForEach-Object (sometimes shortened to foreach) on the images calling your $doc.Add() but right before also calling $doc.NewPage(). You'll want to use Get-ChildItem to get all of the images in a given folder.
