This has a fitz module which makes it very easy to extract images from a PDF file. When we have to extract images from PDF, we can use PyMuPDF. So, in this way, we can extract texts out of a PDF file using the PDFMiner. We can extract texts from a PDF file by the help of process_page function.įinally, the print(text) function will print out the extracted text from a PDF. ![]() We are giving "sample.pdf" as a PDF file to be analyzed and processed using PDFMiner. Using these, the TextConverter function converts a PDF document into texts. LAParams loads up the Layout analysis of character, textbox, textlines, images and figures. PDFPage is used to perform page by page analysis of information. According to the PDFMiner documentation, PDFPageInterpreter is used to process page contents while PDFResourceManager is used to store shared resources such as fonts or images. getvalue()įirst, we have to import the necessary functions and classes from the PDFMiner module. ![]() # path to our input file pdf_file = "sample.pdf" # Extract text pdfFile = open( pdf_file, "rb")įor page in PDFPage. Interpreter = PDFPageInterpreter( rsrcmgr, device) layout import LAParams # PDFMiner Analyzers rsrcmgr = PDFResourceManager()ĭevice = TextConverter( rsrcmgr, sio, codec = codec, laparams = laparams) converter import TextConverter from pdfminer. pdfinterp import PDFPageInterpreter, PDFResourceManager from pdfminer. You can install PDFMiner by running the following command.įrom io import StringIO from pdfminer. Thus, in this section we will demonstrate the usage of PDFMiner for Text Extraction.įirst, we have to install PDFMiner. When it comes to extracting texts from PDFs, PDFMiner is considered to be the most robust library used to perform the text extraction operation. ![]() PDFMiner does the work for us by analyzing the layouts and guessing the position of texts and other contents. But, they do not have a logical structure specified for sentences or paragraphs and cannot adapt themselves when the size of display changes. They provide information on the exact position of a display or a paper. PDFs are the graphical representations of information. PDFs are composed of different contents like: Texts, Images, Tables, Forms, etc. Thus, on the basis of easiness and reliability, we will discuss various libraries that are used to manipulate PDF files in this tutorial. There are several cases where one library is better than other in different aspects when it comes to manipulating the PDF files. PDFMiner was specially developed to extract texts from PDF files. However, when it comes to extracting texts, PDFMiner is much more accurate and reliable. It is easy to use and it has a lot of features. PyPDF2 is the most widely preferred Python module while working with PDFs. While there are several libraries that are used to perform various functional operations with PDFs in Python, we will only cover the usage of a few libraries like PDFMiner, PyPDF2, PyMuPDF, reportlab etc in this chapter. Some popular libraries that are used oftenly while working with PDFs are: Python provides a pool of libraries that are used to manipulate a PDF file. Here, we will be performing some serious stuff like: Extracting and Adding Pages, Texts, Images, Tables, Watermark and much more on a PDF file using Python. This file format was developed by Adobe in 1993 to present documents, including formatted texts and images in a manner that is independent of applications, software, hardware and operating systems. PDFs or the Portable Document Format is a file format of a document consisting of texts, images, tables, etc which are generally used when we need to save files that cannot be further modified or be easily shared or printed. ![]() In this tutorial, we will be working on PDFs using Python. Thus, this language is mostly preferred among developers and engineers. Python has a reach in various fields like Machine Learning, Cybersecurity, Web Development, Application Development etc. It is a high level language with simple syntax. Python is a highly versatile language with a huge set of libraries.
