Python PNG to SVG

Do you need to convert PNG files to SVG? Fear not! With Python, you can easily automate this process. In this tutorial, we will show you how to convert a PNG file to an SVG file using Python.

Requirements

Before we get started, you will need the following:

• Python 3.x
• Pillow library (pip install pillow)
• Potrace library (sudo apt-get install potrace)

Steps

Step 1: Load the PNG image

The first thing we need to do is load the PNG image into Python. To do this, we will use the Pillow library.

from PIL import Image

image = Image.open("example.png")

Step 2: Convert PNG to BMP

Since Potrace cannot directly process PNG files, we need to convert the PNG file to BMP format. We can do this using the convert function of the Pillow library.

bmp_image = image.convert("RGB")
bmp_image.save("example.bmp")

Step 3: Run the Potrace command

To convert the BMP file to SVG, we need to run the potrace command. We can use the subprocess module in Python to do this.

import subprocess

subprocess.call(["potrace", "example.bmp", "-s", "-o", "example.svg"])

Step 4: Load the SVG file

Finally, we can load the SVG file into Python using the svglib library.

from svglib.svglib import svg2rlg
from reportlab.graphics import renderPDF, renderPM

drawing = svg2rlg("example.svg")
renderPM.drawToFile(drawing, "example.png", fmt="PNG")

Conclusion

We hope you found this tutorial helpful in converting your PNG files to SVG format using Python. With just a few lines of code, you can easily automate this process and save time on your design projects.
