#Pdf extract text python pdf# we make our dictionary that maps each pdf page to its corresponding file # if pages is not set, default is all pages of the input PDF document # print the arguments, just for logging purposes # parse the arguments from the command-line If not specified, all text is joined and will be written together") Parser.add_argument("-b", "-by-page", action="store_true", Parser.add_argument("-o", "-output-file", default=sys.stdout, Help="The pages to extract, default is all") Parser.add_argument("file", help="Input PDF file") The following function parses the arguments and does some processing: def get_arguments():ĭescription="A Python script to extract text from PDF documents.") Since we're going to make a Python script that extracts text from PDF documents, we have to use the argparse module to parse the passed parameters in the command line. PyMuPDF has the name of fitz when importing in Python, so keep that in mind. Open up a new Python file, and let's import the libraries: import fitz #Pdf extract text python installTo get started, we need to install PyMuPDF: $ pip install PyMuPDF=1.18.9 If you want to extract text from images in PDF documents, this tutorial is for you. This tutorial tackles the problem when the text isn't scanned, i.e., not an image within a PDF. ![]() In this tutorial, you will learn how you can extract text from PDF documents in Python using the PyMuPDF library. Among them are invoices, receipts, documents, reports, and more. This could improve the OCR recognition by PyTesseract significantly for some images.Disclosure: This post may contain affiliate links, meaning when you click the links and make a purchase, we receive a commission.Īt these times, companies of mid and large-scale have large amounts of PDF documents being used daily. ![]() Scale the image to the optimal sizeĭepending on the image you can increase the size of the image: double the width and height. The lighter version is performing much better in comparison to the dark one. It may work for you just fine, it wasn't designed to run on your platform. While the bad example is here and the result is: De ee ec Ec Please keep this in mind if you run into problems. May work for you just fine, it wasn't designed to run on your platform. You are running Workbench on an unsupported operating system. The good version is and the ouput is: Unsupported Operating System #Pdf extract text python how toHow to improve the OCR results Use white color themes (dark text on white background)īelow you can see two examples of a good and a bad image containing one and the same text but giving completely different results: Text = pytesseract.image_to_string(im, lang='eng') Then open image by image and extract the text: from PIL import Imageįor root, dirs, filenames in os.walk(indir): If you have more than one image you can iterate over all and extract the text by os.walk. Only for PDF example you need to install imagemagick binding of python 3: pip install wand Text = pytesseract.image_to_string(image, lang = 'eng') ImageBlobs.append(imgPage.make_blob('jpeg')) PdfFile = wi(filename = ""/home/user/sample.pdf"", resolution = 300) read images one by one and extract the text with pytesseract / tesserct-ocr. ![]()
