I am taking a screenshot of a specific region and i want to extract the screenshot image to string but it is empty

Here is the code for grabing and extracting it to text:

import pyscreenshot as ImageGrab
from PIL import Image, ImageEnhance, ImageFilter
import pytesseract

Set the path to Tesseract executable

pytesseract.pytesseract.tesseract_cmd = r’C:/Program Files/Tesseract-OCR/tesseract.exe’

class MyUtils:
ROBOT_LIBRARY_SCOPE = ‘Global’
ROBOT_LIBRARY_VERSION = 1.0

def __init__(self):
    print("Initializing MyUtils")

def image_grabs(self, x1, y1, x2, y2, image_name):
    """
    Capture a screenshot of a specified region and save it to a file.
    """
    im = ImageGrab.grab(bbox=(int(x1), int(y1), int(x2), int(y2)))
    im.save(f"./Temp/{image_name}.png")
    print(f"Saved screenshot as {image_name}.png")

def enhance_and_extract_text(self, image_path):
    """
    Enhance the contrast of the image and extract text using OCR (Tesseract).
    """
    try:
        # Open the image
        img = Image.open(image_path)
        print(f"Original image mode: {img.mode}")

        # Convert to grayscale
        img = img.convert('L')
        print(f"Converted image mode: {img.mode}")

        # Enhance image contrast
        enhancer = ImageEnhance.Contrast(img)
        enhanced_img = enhancer.enhance(2.0)  # Enhance contrast by a factor of 2

        # Apply filter to remove noise
        enhanced_img = enhanced_img.filter(ImageFilter.MedianFilter())
        enhanced_img = enhanced_img.filter(ImageFilter.SHARPEN)

        # Save enhanced image temporarily
        enhanced_img_path = image_path.replace('.png', '_enhanced.png')
        enhanced_img.save(enhanced_img_path)
        print(f"Enhanced image saved to: {enhanced_img_path}")

        # Extract text using Tesseract OCR
        extracted_text = pytesseract.image_to_string(enhanced_img, config='--psm 6 -l eng')  # Use page segmentation mode 6 (Assume a single uniform block of text)
        cleaned_text = extracted_text.strip()
        print(f"Extracted text: {cleaned_text}")

        # Return cleaned text
        return cleaned_text

    except Exception as e:
        print(f"Error occurred: {e}")
        return ""

Any suggestion?

I take a screenshot enhanced the screenshot image and then extracted to text using OCR
