# hydrogen-captcha
This is a customizable captcha image generator.
## Usage
```java
CaptchaGenerator captchaGenerator = new CaptchaGenerator();
BufferedImage image = captchaGenerator.generate(200, 50, "ABCDEF");
```
Load fonts from a directory and `CaptchaGenerator` will use them:
```java
FontRepository.loadFonts("./sample-fonts/");
```
Setup a background:
```java
captchaGenerator.setBackground(new CirclesBackground());
// or
captchaGenerator.setBackground(new GradientBackground(true));
```
And you can add effects on both background and char images:
```java
captchaGenerator.addBackgroundFilter(new CrossFilter(10, 1, true));
captchaGenerator.addCharImageFilter(new CrossFilter(10, 1, true));
```
And you can also create your own effects!
