我无法在Python脚本中使用魔杖的图像功能

Question

  

试图通过使用Wand ImageMagic来提高图像质量，并使用Pytesseract OCR获得准确的输出

 My Code TO convert Scanned PDF to Text File 

import sys
import io
from pdf2image import convert_from_path

try:
    from PIL import Image
except ImportError:
    import Image
import pytesseract

import re
import os

directory = r"C:/Users/ahmed.nizamuddin/Desktop/PDF/"


for filename in os.listdir(directory):
    if filename.endswith(".pdf"): 
        print(filename)
        pages = convert_from_path( str(filename), 960)
        content = "" 
        for page in pages:
            page.save("%s-page-%d.jpg" % (filename.split('.pdf')[0],pages.index(page)), "JPEG")
            image_name = "%s-page-%d.jpg" % (filename.split('.pdf')[0],pages.index(page))

            text_name = "%s.txt" % (filename.split('.pdf')[0])            
            image_to_convert = image_name
            
            text_to_save = r"C:/Users/ahmed.nizamuddin/Desktop/PDF/Text/" + text_name
            
            print(image_to_convert)
            #print (image_to_convert)

            content += pytesseract.image_to_string(Image.open(image_to_convert))
            #list.append(content)
                #page.delete("%s-page-%d.jpg" % (filename.split('.pdf')[0],pages.index(page)
                #print(content)
            os.remove(image_to_convert)
            with open(text_to_save,'a') as out:
                out.write(content)
                

  

现在我想使用魔杖包装，以便在Pytesseract OCR之前可以提高图像质量。有人可以告诉我怎么做吗？
