- Apply OCR to the logo image to convert it into text.
- Display this text in HTML.
Install the library in advance
bash
#For step 1
pip install beautifulsoup4
#For step 2
brew install tesseract
pip install pyocr
#For step 3
pip install jinja2
Run
** Step 1: Download logo image **
python
import requests
from bs4 import BeautifulSoup
#Get html
url = 'https://www.google.com'
res = requests.get(url)
soup = BeautifulSoup(res.text, 'html.parser')
#Extract image
img = soup.find('img', {'id': 'hplogo'})
#Create URL for image
img_url = 'https://www.google.com' + img['src']
#Download image
r = requests.get(img_url)
#Save image
with open('hplogo.jpg' ,'wb') as file:
file.write(r.content)
** Step 2: Convert logo image to text with OCR **
python
from PIL import Image
import pyocr
import pyocr.builders
#Preset 1
tools = pyocr.get_available_tools()
tool = tools[0]
#Preset 2
builder = pyocr.builders.TextBuilder()
#Load image
img = Image.open('hplogo.jpg')
#Run OCR
result = tool.image_to_string(img, builder=builder)
** Step 3: Display the text in HTML **
python
from jinja2 import Template
#Generate view
html = '''
<!DOCTYPE html>
<html lang="en">
<head>
<title>The Farther Reaches Of Human Nature</title>
</head>
<body>
<h1>{{ result }}</h1>
</body>
</html>
'''
template = Template(html)
data = { 'result': result }
view = template.render(data)
#Save
with open('hplogo.html', 'w', encoding='utf-8') as f:
f.write(view)
When you open the generated hplogo.html in your browser, you should see the text "Google" as follows: (Image reprinted)
