QUESTION
I have an issue with data hiding.When I print the extracted data as text, every data is shown properly. Below code is for printing extracted data and output is also given.

QUESTION
i would like to use ocrmypdf to convert some pdf-file from a picture to a readable pdf -
Tried it with the following simple code: (the invoice.pdf is of course available in the same path as the python-script and the output.pdf should be generated)
...ANSWER
Answered 2022-Jan-15 at 19:26Sometimes the first error message may be misleading without a clear cause
In this case the primary message "The system cannot find the specified file"
Will lead a user to concentrate on why a filename is not correct, as in this case.
What the error should report is that a required file in the dependencies was not found. which can be caused by one or more Tesseract or related Leptonica / Language data files not in the correct location either due to no install or poor install.
It transpired that installing tesseract on windows from https://github.com/UB-Mannheim/tesseract/wiki "the script now works fine"
Note a missing dependency was the cause of a similar message here Import ocrmypdf in Visual Stdio Code in Python
QUESTION
In a python script I am watching a directory for new files coming from a scanner. Currently my code is only reacting on the IN_CLOSE_WRITE event. I am aware that the right way would be to watch out for a IN_CREATE event followed by a IN_CLOSE_WRITE event.
My current code looks like this:
...ANSWER
Answered 2021-Sep-28 at 16:22Add the created files to a set, then check the set when you get the IN_CLOSE_WRITE event.
QUESTION
I'm using OCRmyPDF to extract text form scanned pdf files. I use codes from this Colab notebook for that purpose. The only difference is that instead of downloading the pdf file from an online url, I use the pdf file stored on my local machine (replaced it {file_name} instead of {invoice_pdf}). Everything looks fine up to the point I run:
...ANSWER
Answered 2021-Jan-05 at 08:18If the file name contains spaces, then you need to enclose the name in quotation marks.

I am using ocrmypdf library for the conversion of scanned pdf to searchable pdf but I got this error.
This is the code that I am currently running

QUESTION
I'm making a PDF Tool executable using tkinter. Anyways, the executable was successfully created by pyinstaller, but it won't run. I flagged --onedir and added the necessary dependency files --add-data. I also added the paths to my non standard library packages using --paths flag. When I run the executable from the command prompt, I get this:
The problem appears to come from the ocrmypdf module and says pkg_resources.DistributionNotFound. I tried searching for the fix, but all the problems I saw were a bit different from my issue because the .py script runs just fine for me. Is this a pyinstaller issue, or am I missing a module? I'm using pyinstaller 4.0 as well.
...ANSWER
Answered 2020-Oct-22 at 01:34After researching a little bit more, I've found the solution. The problem lies with pyinstaller, not the ocrmypdf module. The solution is that you have to create hook py scripts within a folder in your project. It's a little bit different depending on which module you use, but for this case, I had to create two hook py scripts within a folder that I called 'hooks'. These are the two scripts I made:
hook-ocrmypdf.py
QUESTION
I'm only able to use this button's callback once due to how I set up the 'command=' argument. I would like to be able to run this callback function again once it is finished, but I'm at a loss for how I can give the 'command=' argument a new thread object. I press it once and go through the process of the function, but once I press the button again after it is finished, I get 'RuntimeError: threads can only be started once.' Here is the code for the button and the callback:

Answered 2020-Oct-18 at 04:32You should probably start the thread from a launch function, instead of from inside the button command.

QUESTION
I'm using ocrmypdf. I'm trying to do ocr on campaign finances pdfs. Example pdfs: https://apps1.lavote.net/camp/comm.cfm?&cid=11
My clients wants to parse these pdfs, as well as others (form 496s, form 497s). The problem is, even with forms of the same type, the ocr results are inconsistent.
For example, one pdf (form 460) will yield these results:
...ANSWER
Answered 2020-Sep-07 at 18:17I imagine the difference between "identical" Form 460's is a
vertical misalignment due to one being scanned
at a slight CW angle and another at a slight CCW angle.
I hope you are invoking with --deskew,
but even with that there may be minor aberrations that prove troublesome.
The vertical separation between the dates seems large and robust, so one date will precede the other in the proper way. Consider focusing more on the mm/dd/yyyy pattern and less on the text anchors.
You can obtain bound box coordinates from Tesseract OCR. Use them to disambiguate dates, based on your knowledge of what appears higher or lower on the form, and by (approximately) how much.
QUESTION
I am new to Python and coding in general. I'm trying to create a program that will OCR a directory of PDFs then extract the text so I can later pick out specific things. However, I am having trouble getting pdfPlumber to extract all the text from all of the pages. You can index from start to an end, but if the end is unknown, it breaks because the index is out of range.
...ANSWER
Answered 2020-Jul-09 at 20:54The pdfplumber git page says pdfplumber.open returns an instance of the pdfplumber.PDF class.
That instance has the pages property which is a list of pdfplumber.Page instances - one per Page loaded from your pdf. Looking at your code, if you do:
QUESTION
I'm trying to build OCRmyPDF under Cygwin and have run into a brick wall. While I've been a developer my entire career, I've worked mostly in Java and have little knowledge of Python internals and C++. The problem might be obvious to an expert in these areas but I'm stumped.
OCRmyPDF on Linux installs as a set of "wheel" packages. I gather a wheel is a pre-built bundle of dependencies. For some reason, under Cygwin the pip installer believes it cannot use the wheel bundles and wants to rebuild from source. The problem occurs when trying to rebuild the pikepdf package.
Here's the error:
