Scrpit to convert your beautiful draw.io drawings into pdfs.

DrawIO2PDF

Intro

Always wondered how to make beautiful mathematical figures with latex inside them? You can use tikz but it's learning curve is steep and many only ascended people can use it fluently. How about draw.io? It allows you to make beautiful figures. What's better, you can latex-type there. But what is that? Have you tried to export it into PDF? No? I don't recommend that if you have a figure full of maths and you still want to have your eyes unharmed.

This is why I created this tool. You can export your figures from draw.io without worrying that it will break any math font. The output is essentially unrecognizable from a standard tikz figure. It will look beautiful in your PDF document and since it's a vector graphic, everyone can zoom in to take a deeper look into your diagram.

Requirements

• inkscape >= 1.0
• pdflatex (I use sudo apt-get install texlive-full for that)
• python >= 3.6

Installation

From the pip repository:

pip install drawio2pdf

or from git:

pip install git+https://github.com/kacperkan/drawio2pdf/

Usage

1. Create your beautiful diagram, using latex formulas and so on.
2. Disable Extras > Mathematical Typesetting.
3. Export your diagram with SVG.
4. drawio2pdf <path-where-you-saved-your-svg>.

The script will a PDF in the same folder and the same file name.

The result:

FAQ

Q: I get AssertionError: Incorrect PDF latex generation while running you script!

A: I met these issue personally in one of the following cases:

• I didn't have pdflatex or inkscape that was runnable from the console
• I accidentally put a new line in the math formula. When using Mathematical Typesetting, draw.io will render it correctly. However, the SVG file content will be completely broken and it's not that obvious how to parse it with the ETree in python. Solution: Remove any newline in mathematical formulas so they're one liners
• I totally forgot to turn Mathematical Typesetting off.
