Optimized Code for Converting Web-Based SVG to PNG & PDF

This script efficiently downloads an SVG file from the web and converts it into PNG and PDF formats using

📌 Key Improvements

1. Dynamic File Path Management using os (instead of hardcoded paths).
2. Added SVG File Download using requests.
3. Improved Error Handling with try-except.
4. Automatic Directory Creation for saving files.
5. Enhanced PNG Conversion with a white background for better OCR recognition.

📌 Optimized Code

python
import os
import requests
import cairosvg

# ============================
# Configuration: Set File Save Path
# ============================
SAVE_DIR = os.path.join(os.getcwd(), "svg2png")
os.makedirs(SAVE_DIR, exist_ok=True)  # Create the directory if it doesn't exist

# Define file paths
pdf_path = os.path.join(SAVE_DIR, "output.pdf")
png_path = os.path.join(SAVE_DIR, "output.png")

# ============================
# Web SVG File URL
# ============================
thumbnail_template_url = "http://XXXXXX/608d3e7fdae14.svg"

try:
    # ============================
    # 1. Download SVG File
    # ============================
    response = requests.get(thumbnail_template_url)
    if response.status_code == 200:
        svg_data = response.content  # Store the SVG data

        # ============================
        # 2. Convert SVG to PDF
        # ============================
        cairosvg.svg2pdf(bytestring=svg_data, write_to=pdf_path, dpi=100)
        print(f"✅ PDF conversion successful: {pdf_path}")

        # ============================
        # 3. Convert SVG to PNG (With Background)
        # ============================
        cairosvg.svg2png(bytestring=svg_data, write_to=png_path, background_color="white", dpi=100)
        print(f"✅ PNG conversion successful: {png_path}")

    else:
        print(f"⚠️ Failed to download SVG file (Status Code: {response.status_code})")

except Exception as e:
    print(f"❌ Error encountered: {e}")

📌 Key Enhancements

1. Automated File Path Handling

   • Uses os.getcwd() to dynamically set the save directory.
   • Ensures all files are stored in the same folder.

2. Directly Downloads SVG from the Web

   • Uses the requests module to fetch the SVG file and store it in memory.

3. Better Error Handling

   • Includes try-except blocks to catch errors and display useful messages.

4. Background Color for PNG

   • Sets a white background to improve OCR recognition accuracy.

🚀 Expected Output (Successful Execution)

pgsql
✅ PDF conversion successful: /path_to/svg2png/output.pdf
✅ PNG conversion successful: /path_to/svg2png/output.png
