Generates Math-Based Captcha Images With Noise, Grid, And Wave Effects To Help Prevent Automated Access.

• Generates Random Math Captcha (e.g., 3+5=?)
• Renders Clean PNG Captcha With Noise And Distortion
• Includes Background Grid And Wave Layers (Depth Effect)
• Easy To Customize Color, Noise, And Wave
• Outputs PNG Images Ready For Use

1️⃣ Install Dependencies

npm install

2️⃣ Run Example Generator

node example.js

Each Run Generates A PNG Captcha With Dynamic Design And Math Challenge

• Modify Colors, Noise Level, And Wave Effect In src/index.js
• Change Output Location And File Naming In example.js
