![]() Hi, thanks very much but I found a Java API that solves my problem, thanks to this web page: It is obviously possible to process the editable text in a line-by-line left to right manner, because the "Read out Loud" tool does it. So, how do I extract editable text in a line-by-line fashion? Do I have to write code to parse the pdf file? God I hope not. The issue seems to be that the copy operation proceeds in a kind of vertical columnar manner from left to right, over the entire page. If I then paste the selected text into a plain text file, I get a completely jumbled result which cannot possibly be parsed into what I want. If I simply try to use the mouse to select the main body of the page (which contains a table of transactions with mm/dd date on the left, a description, and a dollar amount), as I drag the selected area across the page, the selected area expands upward and downward to include editable text at the top and bottom of the page, which I don't want. Now I need to know how to extract the editable text from the resulting file line-by-line like the "Read out Loud" tool does. I am able to successfully use the OCR scanning tool to create a pdf file which contains editable text and images. Test it out ( python flask_server/cli.py) with a few image urls, or play with your own ascii art for a good time.I am trying to convert some photocopied bank statements into a more usable form. Line by line we look at the text output from our engine, and output it to STDOUT. image_to_string ( image ) " \n " ) sys. write ( "The raw output from tesseract with no processing is: \n\n " ) sys. write ( "A simple OCR utility \n " ) url = raw_input ( "What is the url of the image you would like to analyze? \n " ) image = get_image ( url ) sys. content )) if _name_ = '_main_' : """Tool to test the raw output of pytesseract with a given input URL""" sys. Import sys import requests import pytesseract from PIL import Image from StringIO import StringIO def get_image ( url ): return Image. Speaking of images, we need ImageMagick as well if we want to toy with (edit) the images before we throw them in programmatically. Beyond that, we grab Python 2.7, our programming language of choice, along with the python-imaging library for interaction with all these pieces. We then grab a number of libraries that allow us to toy with images - i.e., libtiff, libpng, etc. Put simply, sudo apt-get update is short for “make sure we have the latest package listings”. $ sudo apt-get build-dep python-imaging -fix-missing $ sudo apt-get install tk8.5 tcl8.5 tk8.5-dev tcl8.5-dev $ sudo apt-get install libopencv-dev libtesseract-dev ![]() $ sudo apt-get install autoconf automake libtool If you’re running OSX, you can use VirtualBox, Docker (check out the Dockerfile along with an install guide are included) or a droplet on DigitalOcean (recommended!) to create the appropriate environment. This post has been tested on Ubuntu version 14.04 but it should work for 12.x and 13.x versions as well. As always, configuring your environment is 90% of the fun. This will not be covered by the tutorial, but you will have access to the code.įirst, we have to install some dependencies. We’ll also add a bit of back-end code to generate an HTML form as well as the front-end code to consume the API. All of this is covered in detail by the tutorial. From there you can just hit the endpoint and serve the results to the end user in the manner that suits you. We’ll start by developing the Flask back-end layer to serve the results of the OCR engine. A trivial example is a basic OCR tool used to extract text from screenshots so you don’t have to re-type the text later on. ![]() ![]() With the advent of libraries such as Tesseract and Ocrad, more and more developers are building libraries and bots that use OCR in novel, interesting ways. OCR (Optical Character Recognition) has become a common Python tool. The following is a collaboration piece between Bobby Grayson, a software developer at Ahalogy, and Real Python. ![]()
