How to contribute

------------

PRs are welcome :)

This library uses static map of width of every ASCII letter for all supported fonts.

1. Clone the repository

2. Open file ```src/pixelWidthCalculator.html``` in your editor

3. Add your font name into array of fonts (currently var websafe) and save

4. Open up ```src/pixelWidthCalculator.html``` in Google Chrome. It should look like this:

![PHPStan](docs/string-pixel-width-1.png)

5. Map of withs will be generated for you - copy it and replace content of file ```src/widthsMap.js```

**Please everytime make sure you don't broke existing fonts - remove any font or broke his widths.**
