README

This is a fork of Gregwar/Tex2png updated to PHP 8.1

Tex2png

This class provides a way to create easily LaTeX formulas.

With it, you can convert raw formulas like:

\sum_{i = 0}^{i = n} \frac{i}{2}

To nice images like:

Requirement

To use this library you'll need :

• latex : to compile formulas (with math support)
• dvipng : to convert dvis to png
• shell_exec : you need to be able to call the php shell_exec() function

You'll also need a temporary folder and, of courses, enough permissions to write to the target directory

Installation

composer require metalinspired/tex2png

Usage

<?php

// This will create a formula and save it to sum.png
(new Tex2png('\sum_{i = 0}^{i = n} \frac{i}{2}'))
    ->saveTo('sum.png')
    ->generate();

Changing the density

The second constructor parameter is the image density :

<?php

(new Tex2png('\sum_{i = 0}^{i = n} \frac{i}{2}', 300))
    ->generate();

Default density is 155, you can choose to generate really big images, this is an example of the formula with a density of 1000 :
