LaTeX Formula Skeleton Generator

This repository provides a solution for generating the skeleton of LaTeX formulas using the latex, dvisvgm, cairosvg, and skimage libraries. The process involves converting LaTeX formulas to DVI, SVG, and PNG formats, followed by skeleton extraction using the Lee algorithm.

The latex_symbols.csv has been generated from https://artofproblemsolving.com/wiki/index.php/LaTeX:Symbols

Requirements

To use this code, ensure you have the following dependencies installed:

• latex command-line tool
• dvisvgm command-line tool for converting DVI to SVG
• cairosvg for converting SVG to PNG
• numpy and pandas for data processing
• skimage for skeleton extraction

Usage

1. Set up the output directory by modifying the output_dir variable in the .env file
2. Create a CSV file named latex_symbols.csv with columns: Name and Symbol for each LaTeX symbol(formula) to be processed
3. copy the .env-sample as .env and modify the variables if needed
4. Run main.py
5. Generated files will be available under the paths provided in the .env file

Please ensure that you have the necessary dependencies installed and configured properly before running the code.

Feel free to customize the code and adapt it to your specific requirements.
