+# 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:
+   ```bash
+   # On macOS
+   brew install wkhtmltopdf
+   
+   # On Ubuntu/Debian
+   sudo apt-get install wkhtmltopdf
+   ```
+
+2. Convert HTML to PNG:
+   ```bash
+   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:
+   ```bash
+   npm install puppeteer
+   ```
+   
+3. Create a conversion script:
+   ```javascript
+   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:
+   ```bash
+   pip install selenium
+   ```
+   
+2. Make sure you have ChromeDriver installed
+
+3. Run the following script:
+   ```python
+   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:
+   ```bash
+   pip install playwright
+   playwright install chromium
+   ```
+   
+2. Run the following script:
+   ```python
+   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
