Convert scanned pdf to text python

Question

I have a scanned pdf file and I try to extract text from it. I tried to use pypdfocr to make ocr on it but I have error:

\"could not found ghostscript in

Answer 1

Take a look at my code it is worked for me.

import os
import io
from PIL import Image
import pytesseract
from wand.image import Image as wi
import gc



pdf=wi(filename=pdf_path,resolution=300)
pdfImg=pdf.convert('jpeg')

imgBlobs=[]
extracted_text=[]

def Get_text_from_image(pdf_path):
    pdf=wi(filename=pdf_path,resolution=300)
    pdfImg=pdf.convert('jpeg')
    imgBlobs=[]
    extracted_text=[]
    for img in pdfImg.sequence:
        page=wi(image=img)
        imgBlobs.append(page.make_blob('jpeg'))

    for imgBlob in imgBlobs:
        im=Image.open(io.BytesIO(imgBlob))
        text=pytesseract.image_to_string(im,lang='eng')
        extracted_text.append(text)

    return (extracted_text)

I fixed it for me by editing the /etc/ImageMagick-6/policy.xml and changed the rights for the pdf line to "read|write":

Open the terminal and change the path

cd /etc/ImageMagick-6
nano policy.xml
 
change to

exit
