During the development of a personal project, I needed to build a script that converts Farsi (Persian) text into an image. To make the process easier — and a bit more fun — I chose the excellent Gradio framework to build a simple interactive interface.
Gradio is a popular open-source Python library that makes it easy to create interactive, web-based UIs for machine learning models, APIs, or even plain Python functions. It’s a favorite among data scientists and ML engineers who want to quickly share their work — no HTML, CSS, or JavaScript required.
Gradio also has a new serverless option, Gradio-Lite, which is amazing for quick demos, but unfortunately it’s not suitable for this project.
Installing Gradio
I prefer using uv as my package manager since it’s blazing fast (thanks to Rust under the hood):
uv add gradio Installing libraqm
Farsi uses a complex script where the shape of each character depends on its position in the word. To render it correctly, we need libraqm, which handles text shaping.
Here’s how to install it:
macOS
Using Homebrew:
brew install libraqm If you’re using fish shell, you’ll also need to update your PKG_CONFIG_PATH:
set -gx PKG_CONFIG_PATH "(brew --prefix libraqm)/lib/pkgconfig:$PKG_CONFIG_PATH" Windows
Follow this StackOverflow answer for installation instructions.
Installing Pillow
Once libraqm is set up, install Pillow with:
uv pip install Pillow --no-binary=Pillow This ensures Pillow is compiled with libraqm support.
Converting Farsi Text to an Image
Now that everything is installed, we can write a simple script that takes:
- A font file
- Your Farsi text
- Image dimensions
Here’s the script:
Run the script, then open your app at:
http://localhost:8007/
Here’s the result 🎉
