Why another captcha generator?

I want a simple and framework-independent way to generate captcha. It also should be flexible, at least allow me to pick my favorite font.

install

go get github.com/steambap/captcha

usage

func handle(w http.ResponseWriter, r *http.Request) {
	// create a captcha of 150x50px
	data, _ := captcha.New(150, 50)

	// session come from other library such as gorilla/sessions
	session.Values["captcha"] = data.Text
	session.Save(r, w)
	// send image data to client
	data.WriteImage(w)
}
