defaultDimension: SetDimensionOption = ...

Default dimensions for CAPTCHA images.

These dimensions provide a good balance between readability and file size, suitable for most web applications and forms. The 3:1 aspect ratio allows for comfortable text spacing.

Example: Using default dimensions

const captcha = new Captcha(); // Uses 300x100 by default

Example: Scaling from defaults

const largeCaptcha = new Captcha(
  defaultDimension.width * 1.5,  // 450px wide
  defaultDimension.height * 1.5  // 150px tall
);
