More detail of the structure of an LTPage is shown by this image from the docs:Įach of the types above has a. (In particular, your textboxes will probably all be LTTextBoxHorizontals.)
Each of these layout objects can be one of the following types. The layout object above is an LTPage, which is an iterable of "layout objects". The meaning of some of the parameters is given at since they can also be passed as arguments to pdf2text at the command line.
#PDF EXTRACT TEXT BOXES PYTHON CODE#
LAParams's parameters are, like most of PDFMiner, undocumented, but you can see them in the source code or by calling help(LAParams) at your Python shell. Therefore, text extraction needs to splice text chunks.
#PDF EXTRACT TEXT BOXES PYTHON PDF#
In an actual PDF file, text portions might be split into several chunks in the middle of its running, depending on the authoring software. If you're surprised that such grouping is a thing that needs to happen at all, it's justified in the pdf2txt docs: LAParams lets you set some parameters that control how individual characters in the PDF get magically grouped into lines and textboxes by PDFMiner. I don't bother handling LTFigures, since PDFMiner is currently incapable of cleanly handling text inside them anyway.I use PDFPage.get_pages(), which is a shorthand for creating a document, checking it is_extractable, and passing it to PDFPage.create_pages().There are a couple of changes I've made from these previous examples:

The code above is based upon the Performing Layout Analysis example in the PDFMiner docs, plus the examples by pnj () and Matt Swain (). Here's a copy-and-paste-ready example that lists the top-left corners of every block of text in a PDF, and which I think should work for any PDF that doesn't include "Form XObjects" that have text in them: from pdfminer.layout import LAParams, LTTextBox from pdfminer.pdfpage import PDFPage from pdfminer.pdfinterp import PDFResourceManager from pdfminer.pdfinterp import PDFPageInterpreter from nverter import PDFPageAggregator fp = open('yourpdf.pdf', 'rb') rsrcmgr = PDFResourceManager() laparams = LAParams() device = PDFPageAggregator(rsrcmgr, laparams=laparams) interpreter = PDFPageInterpreter(rsrcmgr, device) pages = PDFPage.get_pages(fp) for page in pages: print('Processing next page.') interpreter.process_page(page) layout = device.get_result() for lobj in layout: if isinstance(lobj, LTTextBox): x, y, text = lobj.bbox, lobj.bbox, lobj.get_text() print('At %r is text: %s' % ((x, y), text)) add the TextParagraph with TextBuilder.AppendParagraph.add the TextFragment with TextParagraph.AppendLine.
use “\r\n” or Environment.NewLine in TextFragment instead of single “\n”.However in order to add text with a line feed, please use TextFragment with TextParagraph: When adding TextFragment to the paragraphs collection of PDF documents, it does not support line feed inside the text. $P is replaced with the total number of pages in the document. $p is replaced with the number of the page where the current Paragraph class is in. The $p and $P are used to deal with the page numbering at run time. Replaceable symbols currently support by new Document Object Model of Aspose.PDF namespace are $P, $p, \n, \r. Replaceable symbols are special symbols in a text string that can be replaced with corresponding content at run time. Save ( dataDir ) Rendering Replaceable Symbols during PDF creation TextFragments // Loop through the fragmentsįoreach ( TextFragment textFragment in textFragmentCollection ) dataDir = dataDir + "RearrangeContentsUsingTextReplacement_out.pdf" // Save resultant PDFĭoc. TextFragmentCollection textFragmentCollection = textFragmentAbsorber.
