DFD.html to PNG Conversion Guide

Overview

This document provides instructions for converting the DFD.html file to a PNG image.

File Information

• Input file: /Users/home/YandexDisk/TECHNOLYCEUM/ict/Year/2025/ai/ai7/ai7-m3/Thesis materials/DFD.html
• Expected output: DFD.png in the same directory

Method 1: Using Command Line Tools

Option A: Using wkhtmltopdf

1. Install wkhtmltopdf:

   # On macOS
   brew install wkhtmltopdf
   
   # On Ubuntu/Debian
   sudo apt-get install wkhtmltopdf
   

2. Convert HTML to PNG:

   wkhtmltoimage --width 1200 --height 800 "/Users/home/YandexDisk/TECHNOLYCEUM/ict/Year/2025/ai/ai7/ai7-m3/Thesis materials/DFD.html" "/Users/home/YandexDisk/TECHNOLYCEUM/ict/Year/2025/ai/ai7/ai7-m3/Thesis materials/DFD.png"
   

Option B: Using Puppeteer (Node.js)

1. Install Node.js and npm if not already installed

2. Install Puppeteer:

   npm install puppeteer
   

3. Create a conversion script:

   const puppeteer = require('puppeteer');
   const fs = require('fs');
   
   (async () => {
     const browser = await puppeteer.launch();
     const page = await browser.newPage();
   
     // Read the HTML file
     const htmlContent = fs.readFileSync('/Users/home/YandexDisk/TECHNOLYCEUM/ict/Year/2025/ai/ai7/ai7-m3/Thesis materials/DFD.html', 'utf8');
   
     await page.setContent(htmlContent);
   
     // Take screenshot
     await page.screenshot({ 
       path: '/Users/home/YandexDisk/TECHNOLYCEUM/ict/Year/2025/ai/ai7/ai7-m3/Thesis materials/DFD.png',
       fullPage: true
     });
   
     await browser.close();
     console.log('Conversion completed!');
   })();
   

Method 2: Using Python Libraries

Option A: Using Selenium

1. Install required packages:

   pip install selenium
   

2. Make sure you have ChromeDriver installed

3. Run the following script:

   from selenium import webdriver
   from selenium.webdriver.chrome.options import Options
   import os
   
   # Setup Chrome options
   chrome_options = Options()
   chrome_options.add_argument("--headless")  # Run in background
   chrome_options.add_argument("--no-sandbox")
   chrome_options.add_argument("--disable-dev-shm-usage")
   
   # Initialize the driver
   driver = webdriver.Chrome(options=chrome_options)
   
   # Load the HTML file
   file_url = "file://" + os.path.abspath("/Users/home/YandexDisk/TECHNOLYCEUM/ict/Year/2025/ai/ai7/ai7-m3/Thesis materials/DFD.html")
   driver.get(file_url)
   
   # Set window size and take screenshot
   driver.set_window_size(1200, 800)
   driver.save_screenshot("/Users/home/YandexDisk/TECHNOLYCEUM/ict/Year/2025/ai/ai7/ai7-m3/Thesis materials/DFD.png")
   
   driver.quit()
   print("Conversion completed!")
   

Option B: Using Playwright

1. Install required packages:

   pip install playwright
   playwright install chromium
   

2. Run the following script:

   from playwright.sync_api import sync_playwright
   import os
   
   with sync_playwright() as p:
       browser = p.chromium.launch(headless=True)
       page = browser.new_page()
   
       # Load the HTML file
       file_path = os.path.abspath("/Users/home/YandexDisk/TECHNOLYCEUM/ict/Year/2025/ai/ai7/ai7-m3/Thesis materials/DFD.html")
       page.goto(f"file://{file_path}")
   
       # Set viewport size and take screenshot
       page.set_viewport_size({"width": 1200, "height": 800})
       page.screenshot(path="/Users/home/YandexDisk/TECHNOLYCEUM/ict/Year/2025/ai/ai7/ai7-m3/Thesis materials/DFD.png", full_page=True)
   
       browser.close()
       print("Conversion completed!")
   

Method 3: Manual Conversion

1. Open the DFD.html file in your web browser
2. Take a screenshot of the page (using Cmd+Shift+4 on macOS or PrtScn on Windows)
3. Crop the screenshot to include only the relevant content
4. Save the image as DFD.png in the Thesis materials directory

Verification

After conversion, verify that:

• The PNG file exists in the Thesis materials directory
• The image clearly displays the content from the DFD.html file
• The image quality is sufficient for your needs
