Please mention the version you are using and also show the code you used to generate captcha.

[abdlmutii]

const { CaptchaGenerator } = require("captcha-canvas");

const captcha = new CaptchaGenerator()
.setDimension(150, 450) 
.setCaptcha({color: '#1DAEEF'})
.setDecoy({opacity: 0.5})
.setTrace({color: '#1DAEEF'});

I use latest version..lemme do quick check

[abdlmutii]

Yea. I use latest version.

the variable captcha here will not provide you Buffer. To get Buffer you have to use generateSync method.

I used your code in my PC and it works

Code:

const { CaptchaGenerator } = require("captcha-canvas");
const { writeFileSync } = require("fs");

const captcha = new CaptchaGenerator()
.setDimension(150, 450) 
.setCaptcha({color: '#1DAEEF'})
.setDecoy({opacity: 0.5})
.setTrace({color: '#1DAEEF'});

const captchaImageData = captcha.generateSync();

writeFileSync('captcha.png', captchaImageData);

This code creates a file captcha.png which have the image.

• Re-check your code where you send the captcha image.
• Seeing your image only have a trace line but no text written may be some problem with your system font.
• This package use skia-canvas make sure skia-canvas works on your system.

If your system do not support skia-canvas then you can try v2.3.1 of captcha-canvas. As v2 uses node-canvas for image manipulation. The above code will also work on v2 too.

npm i captcha-canvas@2.3.1

BTW skia-canvas is fast compare to node-canvas.
