TextTTR

NodeJS library that creates illusion image that can only be read when you tilt your screen

Installation

Note

• It uses node-gd as dependency, and node-gd require libgd that currently doesn't supports windows systems.

On Debian/Ubuntu

$ sudo apt-get install libgd-dev
$ npm i text-ttr

On RHEL/CentOS

$ sudo yum install gd-devel
$ npm i text-ttr

On Mac OS/X

Using Homebrew

$ brew install pkg-config gd
$ npm i text-ttr

On Mac OS/X

...or using MacPorts

$ sudo port install pkgconfig gd2
$ npm i text-ttr

Windows

• I am not sure, but if there is some method to install libgd on windows then it would work fine on windows too.

Usage

Simple usage

const textTTR = require("text-ttr");

let img = textTTR({
  text1: "TextTTR",
