How to Convert RTF to GIF Using Python

Converting Rich Text Format (RTF) files to GIF images can be useful for embedding formatted text into presentations, websites, or social media. Python makes this process simple with the right libraries. In this guide, we'll use Pillow (a fork of PIL) and pyth to achieve this conversion efficiently.

Prerequisites

Before starting, ensure you have Python installed. You'll also need these libraries:

Pillow (for image processing)
pyth (for RTF parsing)

Install them using pip:

pip install Pillow pyth

Step-by-Step Conversion Process

1. Parse the RTF File

First, we'll use pyth to extract text and formatting from the RTF file:

from pyth.plugins.rtf15.reader import Rtf15Reader

def parse_rtf(file_path):
    with open(file_path, 'rb') as file:
        doc = Rtf15Reader.read(file)
        return doc

2. Convert Text to Image

Next, we'll use Pillow to render the text as an image:

from PIL import Image, ImageDraw, ImageFont

def text_to_image(text, output_path):
    # Create a blank image with white background
    img = Image.new('RGB', (800, 600), color='white')
    draw = ImageDraw.Draw(img)
    
    # Use a default font (adjust path if needed)
    font = ImageFont.load_default()
    
    # Draw text on the image
    draw.text((10, 10), text, fill='black', font=font)
    
    # Save as GIF
    img.save(output_path, 'GIF')

3. Combine Both Steps

Now, let's merge these functions to convert RTF to GIF:

def rtf_to_gif(rtf_path, gif_path):
    doc = parse_rtf(rtf_path)
    text = doc.content  # Extract plain text (adjust for formatting if needed)
    text_to_image(text, gif_path)

Enhancing the Output

For better results, consider:

Using a custom font (ImageFont.truetype())
Adjusting image dimensions based on text length
Adding background colours or borders

Final Thoughts

With Python and libraries like Pillow and pyth, converting RTF to GIF is straightforward. This method works well for simple text, but for complex RTF files with tables or images, additional processing may be needed.
