![]() ![]() Note that each LTTextBox is a collection of LTChars (characters explicitly drawn by the PDF, with a bbox) and LTAnnos (extra spaces that PDFMiner adds to the string representation of the text box's content based upon the characters being drawn a long way apart these have no bbox). get_text() method, shown above, that returns their text content as a string. In addition to a bbox, LTTextBoxes also have a. mediabox: x0, y0_orig, x1, y1_orig = some_lobj.bbox If it's more convenient for you to work with the y-axis going from top to bottom instead, you can subtract them from the height of the page's. The y-coordinates are given as the distance from the bottom of the page. bbox property that holds a ( x0, y0, x1, y1) tuple containing the coordinates of the left, bottom, right, and top of the object respectively. 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. 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. 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 ( ). X, y, text = lobj.bbox, lobj.bbox, lobj.get_text() Interpreter = PDFPageInterpreter(rsrcmgr, device) 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, LTTextBoxįrom pdfminer.pdfinterp import PDFResourceManagerįrom pdfminer.pdfinterp import PDFPageInterpreterįrom nverter import PDFPageAggregatorĭevice = PDFPageAggregator(rsrcmgr, laparams=laparams) ![]()
