Convert JSON to PNG in Python

We are given JSON data and our task is to convert JSON to PNG in Python using different approaches. In this article, we will explore how to convert JSON data into PNG images using Python.

Convert JSON to PNG in Python

Below are some of the ways by which we can convert JSON to PNG in Python:

1. Using pil Library
2. Using Matplotlib Library

Convert JSON to PNG in Python Using PIL (Pillow) Library

The Pillow library, a fork of the original Python Imaging Library (PIL), is a powerful image-processing library in Python. To use this library for converting JSON to PNG, you can follow the code below: This example uses the Pillow library to create an image, draw the JSON text on it, and save the image as a PNG file.

Python3

from PIL import Image, ImageDraw, ImageFont
import json

def json_to_png(json_data, output_file):
    # Convert JSON to string
    json_str = json.dumps(json_data, indent=4)

    # Create an image with white background
    image = Image.new('RGB', (800, 600), 'white')
    draw = ImageDraw.Draw(image)

    # Set the font and size
    font = ImageFont.load_default()

    # Draw the JSON text on the image
    draw.text((10, 10), json_str, font=font, fill='black')

    # Save the image as PNG
    image.save(output_file)

# Example usage
sample_json = {"name": "John Doe", "age": 30, "city": "Example City"}
json_to_png(sample_json, "example1_output.png")
print('successfully converted JSON to PNG')

Output:

successfully converted JSON to PNG

Convert JSON to PNG Using Matplotlib Library

Matplotlib is a popular plotting library in Python. Though primarily designed for creating charts and graphs, it can be repurposed to visualize JSON data as an image. Here’s an example: This example utilizes Matplotlib to create a text plot, remove axis elements, and save the plot as a PNG file.

Python3

import matplotlib.pyplot as plt
import json

def json_to_png(json_data, output_file):
    # Convert JSON to string
    json_str = json.dumps(json_data, indent=4)

    # Create a text plot
    plt.text(0.5, 0.5, json_str, ha='center', va='center', wrap=True)

    # Remove axis ticks and labels
    plt.axis('off')

    # Save the plot as PNG
    plt.savefig(output_file, bbox_inches='tight', pad_inches=0)

# Example usage
sample_json = {"name": "John Doe", "age": 30, "city": "Example City"}
json_to_png(sample_json, "example2_output.png")
print("successfully converted JSON to PNG")

Output:

successfully converted JSON to PNG

Conclusion

In this article, we explored some different approaches to convert JSON data to PNG images using Python. Whether using image manipulation libraries like Pillow, repurposing plotting libraries like Matplotlib, these examples provide flexibility for various use cases. Depending on your specific requirements and preferences, you can choose the approach that best fits your needs when working with JSON data visualization in Python.
